2005-01-31  Nina Hüffmeyer <[email protected]>

        * Extensions/ogr/ogrdialog.py: Added class ogrdialog.py, which provides
        some dialogs needed to start ogr.
        
        * Extensions/ogr/__init__.py: Changed comments to avoid encoding
        warnings.

        * Extensions/ogr/test/test_OGRShapestore.py: Changed comments to avoid
        encoding warnings.

2005-01-28  Jonathan Coles <[email protected]>

        * libraries/thuban/gdalwarp.cpp (GetImageData): Recode how the
        mask is packed into a bit array. It's now slightly faster.

2005-01-28  Jonathan Coles <[email protected]>

        * Thuban/Model/layer.py (RasterLayer.__init__): Make use_mask
        default to true.

        * Thuban/Model/load.py (SessionLoader.start_rasterlayer): Remove 
        code that loads the state of the layer's use_mask flag. Its 
        usefulness is still being debated.

        * Thuban/Model/save.py (SessionSaver.write_layer): Remove
        code that saves the state of the layer's use_mask flag. Its 
        usefulness is still being debated.

        * Thuban/UI/baserenderer.py (BaseRenderer.draw_raster_layer): Pass
        options to ProjectRasterFile based on the state of layer.UseMask().
        Catch more exceptions from ProjectRasterFile so that Thuban doesn't
        quit is there is a problem projecting.
        (BaseRenderer.draw_raster_data): Change the documentation to 
        describe the new format (XBM) that the mask data will be in.

        * Thuban/UI/renderer.py (MapRenderer.draw_raster_data): The mask
        data is in XBM format when format='RAW' which means it doesn't 
        need to be converted to a wxImage before being used as a mask
        for a wxBitmap. Assume that if format != 'RAW' that the image
        data and mask data are in the same format.

        * libraries/thuban/gdalwarp.cpp (GetImageData): If alpha is enabled
        and a mask is requested, convert the alpha band to a bit array in 
        XBM format. if an alpha channel is requested, simply return the 
        data in the alpha band. Provide better error handling by returning
        python error messages (also fixes RT #2947).
        (ProjectRasterFile): Support multiple mask options, rather than simply
        a flag indicating that a mask should or should not be used. Provide 
        better error handling by returning python error messages.

        * test/test_baserenderer.py (TestBaseRenderer.test_raster_no_projection):
        Add mask data to test.

        * test/test_layer.py (TestLayer.test_raster_layer): Test that a layer
        should use the mask by default.
        (TestLayerModificaton.test_raster_layer): Test that a layer should use 
        the mask by default.

        * test/test_load.py (TestRasterLayer.test): Remove testing for
        use_mask flag in file.

        * test/test_save.py (SaveSessionTest.testRasterLayer): Remove testing
        for use_mask in file.

        * test/test_load_1_0_1.py: Removed. Shouldn't have been checked in.
        
2005-01-26  Jonathan Coles <[email protected]>

        Add a new dialog box for raster layers. The dialog box allows
        the user to toggle a mask that is generated by ProjectRasterFile
        and is used to only draw the real parts of the projected image.

        * Thuban/UI/baserenderer.py (BaseRenderer.draw_raster_layer):
        Instruct the warping code to generate a mask if the raster layer 
        requests one. 
        (BaseRenderer.draw_raster_data): Removed obsolete optional mask argument.

        * Thuban/UI/renderer.py (MapRenderer.draw_raster_data): Removed
        obsolete optional mask argument.

        * Thuban/UI/classifier.py (Classifier): Change the parent class
        to LayerProperties and rework the code to support layout calls
        from the parent.
        (Classifier.dialog_layout): New. Layout the dialog box.
        (Classifier.map_layers_removed): Removed. Moved to parent class.

        dialog boxes.

        * Thuban/UI/rasterlayerproperties.py: New. Class for displaying
        raster layer properties.

        * libraries/thuban/gdalwarp.cpp: Replace the old gdalwarp.cpp code
        with the non-simple version supplied with gdal. This allows added
        features such as creating an alpha band.
        (GetImageData): Generate a mask array from the alpha band that is 
        generated by gdal if the user has selected it. Try to support images 
        that have more than three bands, such as images with RGB plus an 
        alpha band.
        (ProjectRasterFile): Convert python argument for mask and tell
        gdal to enable or disable an alpha band.

        * Thuban/Model/layer.py (BaseLayer.Type): New. Returns a string
        describing what kind of layer the class is. Defaults to "Unknown",
        but should be overridden by subclasses.
        (Layer.Type): New. Override base class method.
        (RasterLayer.__init__): Create a flag for using a mask. Record extra 
        data from gdal for display in the properties dialog.
        (RasterLayer.Type): New. Override base class method.
        (RasterLayer.UseMask): New. Returns True if the mask should be used.

        Classifier classes as dialogs to use with the proper layer types.

        * test/test_baserenderer.py (TestBaseRenderer.test_raster_no_projection):
        Fix test.

        * test/test_layer.py (TestLayer.test_raster_layer): Test new methods.
        (TestLayerModification.build_path): New. Support function.
        (TestLayerModification.test_raster_layer): New. Test new methods.

        * Extensions/ogr/ogrshapes.py: Added two dictionaries to ShapeStore 
        which maps the ids and the ordinals. Fixed RowIdToOrdinal(),
        RowOrdinalToId() and ReadRowAsDict().

2005-01-26  Jan-Oliver Wagner <[email protected]>

        * Doc/manual/thuban-manual-de.xml: More translations.

2005-01-24  Bernhard Herzog  <[email protected]>

        Rework the status bar updates a bit to make sure the message about
        the projections is produced at the right times.

        * Thuban/UI/mainwindow.py (MainWindow.update_status_bar_messages):
        New class variable with messages that may require a status bar
        update.
        (MainWindow.view_position_changed)
        (MainWindow.update_status_bar): Rename from view_position_changed
        to update_status_bar.  It's meaning has changed now that it may
        also generate messages about problems with projection settings.
        (MainWindow.__init__): Use the new update_status_bar_messages
        class variable to subscribe update_status_bar
        (MainWindow.set_position_text): Update doc-string.  This method
        has to be renamed at some point.  See doc-string and comments.
        (MainWindow.OnClose): Unsubscribe update_status_bar from all
        messages in update_status_bar_messages

        * Thuban/UI/viewport.py (ViewPort.forwarded_map_messages): New
        class attribute.  map messages to be forwarded by the viewport.
        (ViewPort._subscribe_map, ViewPort._unsubscribe_map): (un)subscribe
        the messages in forwarded_map_messages

2005-01-21  Bernhard Herzog  <[email protected]>

        * test/postgissupport.py (PostGISDatabase.__init__): Tweak
        doc-string
        (find_postgis_sql): Update for postgis-1.0.0-rc1, which uses a
        different name for the initialization SQL file.

2005-01-21  Jonathan Coles <[email protected]>

        * Thuban/UI/baserenderer.py (proj_params_to_str): New. Takes
        a projection and returns a formatted string representing the 
        parameters to feed to gdalwarp. This function eliminates
        redundancy in draw_raster_layer().
        (BaseRenderer.render_map_incrementally): Removed the optimization which
        drew the top most raster layer first and then only those vector-
        based layers that are above it. With the support for transparency
        this optimization breaks correct behaviour.
        (BaseRenderer.draw_raster_layer): Reorganize code to support possible
        future enhancements to raster layer bounding box. The old behaviour has
        not changed. Also, change calling parameters to draw_raster_data()
        to specify new RAW data format and mask.
        (BaseRenderer.draw_raster_data): Change signature to include an optional
        parameter for mask information. Change documentation to mention
        support for new parameter and added option for RAW data format.
        The data argument is now a list of [width, height, data].

        * Thuban/UI/renderer.py (MapRenderer.draw_raster_data): Add new optional
        mask parameter. Add new condition for RAW format, which 
        significantly reduces rendering time. Add condition for 
        mask parameter.

        * libraries/thuban/gdalwarp.cpp (GetImageData): New. Creates a 
        data array of RGB values from the projected image returned from 
        the gdal warping functions. In the case of palette based images, it
        converts the NO_DATA index to the mask color.
        (ProjectRasterFile): Removed all custom memory driver references
        and replaced it with the standard in-memory dataset provided
        by gdal. The return data is no longer a BMP file, but an array
        of RGB values, one set triple per pixel.

        * libraries/thuban/bmpdataset.cpp: Removed. Unnecessary.
        * libraries/thuban/cpl_mfile.h: Removed. Unnecessary.
        * libraries/thuban/cpl_mfile.cpp: Removed. Unnecessary.

        * setup.py (thuban_build_ext.finalize_options): Removed mention
        of cpl_mfile.cpp and bmpdataset.cpp files in the list of source
        files. These are obsolete with the new version of gdalwarp.cpp

        * test/test_baserenderer.py (SimpleRenderer.draw_raster_data):
        Updated signature.
        (TestBaseRenderer.test_raster_no_projection): Changed the test
        data to be data in the uncompressed RAW format returned from
        ProjectRasterFile.

2005-01-21  Jan-Oliver Wagner <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.view_position_changed): Made
        string available for i18n.

2005-01-20  Russell Nelson  <[email protected]>

        * Resources/Projections/defaults.proj: Ruin the speling of the
        Lambert-93 projection so it doesn't run into the wx UTF-8 bug.
        It's the wrong thing to do in the long run, but it's necessary for
        those users until that bug is fixed.  Otherwise the projection
        dialog segfaults.  Better to annoy some Lambert-93 users with a
        spelling mistake than every Fedora Core 3 user of Thuban-CVS.

2005-01-20  Bernhard Reiter <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.view_position_changed): Added
        docstring and comment that the warning code here is a hack.

2005-01-20  Russell Nelson  <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.view_position_changed): Warn
        user about misprojected layers when their lat/lon bounding
        box exceeds rational lat/lon values.

2005-01-20  Bernhard Reiter <[email protected]>

        * Thuban/UI/about.py (unicodeToLocale): Improved:
        Use 'ascii' and then 'replace' for other characters 
        when getdefaultlocale returns None. Thanks to Bernhard H. .

2005-01-20  Bernhard Reiter <[email protected]>

        * Thuban/UI/classgen.py (GenQuantilesPanel.OnRetrieve): Added a comment
        that OnRangeText might be called twice and using None as argument.

2005-01-20  Bernhard Reiter <[email protected]>

        * Thuban/UI/classgen.py (GenQuantilesPanel.OnRetrieve): Add a
        OnRangeText(0) to work around a different in wx Behaviour noticed
        on MacOSX, thanks to Lorenzo Moretti and Daniel Calvelo for the fix.

2005-01-20  Bernhard Reiter <[email protected]>

        * Thuban/UI/about.py: take iso-8859-15 when getdefaultlocale returns
        None. (Fixes rt#2910.)
        
2005-01-18  Frank Koormann <[email protected]>

        New Extension: mouseposition

        is not part of the layers Classification.

2005-01-03  Frank Koormann <[email protected]>

        * Thuban/UI/renderer.py (ScreenRendererdraw_selection_incrementally):
        BugFix 2883: Former implementation only worked on classified point 
        layers: KeyError was raised, now use the default size if field is None. 

2004-12-27  Bernhard Reiter <[email protected]>

        svgexport 1.0.0cvs: Fixed label export.

        * Extensions/svgexport/test/test_svgmapwriter.py:
        class TestSVGRenderer(): New class; new test test_label_font().

        * Extensions/svgexport/svgmapwriter.py

        Bernhard (coding guidelines etc.). Additionally it is now possible to 
        display shapefiles containing feature collections (e.g.polygons 
        with holes). Works with gdal 1.2.1 now.

        * Extensions/ogr/test/test_OGRShapestore.py: Fixed some issues
        from Bernhard (coding guidelines etc.). If ogr can't be imported,
        tests are skipped now.

        Added Extensions/svgexport/TODO

2004-12-18  Bernhard Reiter <[email protected]>

        Refactored in svgexport:
        DrawPath replaces DrawPolygon; added newline in front of "M" in paths.

        * Extensions/svgexport/svgmapwriter.py
        Added verbosity level 3 to print out polygon points.
        (class Point): added __repr__
        (class Brush, __str__()): Added space after ,.
        (DrawPolygon): Renamed to DrawPath()
        (DrawPath): Takes list of polygons as input now, adds \n before "M"s.
        (DrawLines): Using DrawPath now.

        * Extensions/svgexport/test/test_svgmapwriter.py:
        Replaced DrawPolygon() calls with DrawPath() and put the first argument
        inside another list. Adapted test data with a newline before "M".

2004-12-18  Bernhard Reiter <[email protected]>
        
        Refactored svgexport tests: 9 double tests runs eliminated;

2004-12-17  Bernhard Herzog  <[email protected]>

        Two windows specific fixes ported from thuban-10-branch:

        * Thuban/UI/about.py (unicodeToLocale): Use getdefaultlocale
        instead of getlocale because getlocale doesn't return a usable
        encoding name on a german windows 2000

        * setup.py: windows build: Removed the absolute path names and
        made all prfixes relative to the directory containing setup.py.
        Makes it a little easier to adapt to a different system.

2004-12-16  Bernhard Herzog  <[email protected]>

        Fixes RT#2299

        * Thuban/Model/postgisdb.py (shapetype_map): Add LINESTRING

        * test/postgissupport.py
        (PostgreSQLServer.get_default_static_data_db): Rename the "roads"
        table to "roads-multi" because it now uses MULTILINESTRING
        geometries and introduce a new "roads" table that uses LINESTRING
        (coords_to_multilinestring): Make the doc string more precise
        (coords_to_linestring): New.  Create a LINESTRING WKT
        representatin
        (wkt_converter): Add coords_to_linestring
        (upload_shapefile): Rephrase the doc-string a bit.

        * test/test_postgis_db.py (TestPostGISShapestoreArc)
        (LineStringTests)
        (TestPostGISShapestoreLineString)
        (TestPostGISShapestoreMultiLineString): Split
        TestPostGISShapestoreArc into a base class LineStringTests and two
        derived classes TestPostGISShapestoreLineString for LINESTRING
        geometries and TestPostGISShapestoreMultiLineString for
        MULTILINESTRING geometries.  Most test methods are in the base
        class with the exception of tests that explicitly check the raw
        format.

2004-12-16  Bernhard Herzog  <[email protected]>

        Make the test suite work with PostGIS 0.8.2 and PostgreSQL 7.4

        * test/postgissupport.py (find_postgis_sql): Different postgis
        versions put the postgis.sql file into slightly different places
        so we have to look in both.  The updated doc string describes this
        is more detail.

        * test/test_postgis_db.py
        (TestPostGISSpecialCases.test_column_name_quoting): The return
        value of UniqueValues is unsorted, so it has to be sorted for
        comparison.

2004-12-16  Bernhard Herzog  <[email protected]>

        Fix for RT#2237

        * Thuban/UI/projdialog.py (ProjFrame._show_proj_panel): If the
        panel to be shown is the UnknownProjPanel disable the OK and Try
        buttons.  Otherwise enable them.
        (ProjFrame.__GetProjection): The UnknownProjPanel returns None for
        the parameters.  In that case __GetProjection also returns None
        now.

2004-12-15  Bernhard Herzog  <[email protected]>

        * Thuban/UI/classgen.py (GenQuantilesPanel.__init__): Set the
        minimum number of classes to 2.  The calculate_quantiles needs at
        least two and raises an exception otherwise.  
        Fixes RT#2549

2004-12-15  Bernhard Herzog  <[email protected]>

        * test/postgissupport.py (PostgreSQLServer.execute_sql): Extend to
        so that it returns a result for select statements.
        (PostgreSQLServer.server_version): New.  Return the version of the
        server software.
        (PostgreSQLServer.require_authentication): The format of
        pg_hba.conf has changed between PostgrSQL 7.2 and 7.3.  Check the
        server version and generate the file in the correct format

2004-12-15  Bernhard Herzog  <[email protected]>

        * test/postgissupport.py (PostgreSQLServer.is_running): Fix typo
        in the doc string and rephrase it a little.

2004-12-15  Frank Koormann <[email protected]>

        * test/test_load.py (TestAltPath.checkSession): New, extended checks if
        session has been loaded successfully. The check is called by the relevant
        tests after executing load_session().

2004-12-13  Bernhard Herzog  <[email protected]>

        Make sure the region used to determine which shapes are visible
        actually matches the region on the printed page.  If this isn't
        done properly some shapes might not be printed.  
        Fixes RT #2692

        * Thuban/UI/view.py (MapPrintout.draw_on_dc): The region for the
        renderer has to be at the same position as the mapregion

        * Thuban/UI/renderer.py (ExportRenderer.RenderMap): self.region
        has to be moved by (self.shiftx, self.shifty) too.

2004-12-13  Bernhard Herzog  <[email protected]>

        * libraries/pyprojection/Projection.i: Work around a bug in the
        generated python code which leads to exception in the __del__
        method when the constructor fails.  See the comments in the code
        for more details.

        * libraries/pyprojection/Projection.py: Updated from Projection.i
        with SWIG.

2004-12-13  Bernhard Herzog  <[email protected]>

        * test/test_load.py (TestAltPath.test_01_single_path_error_fix)
        (TestAltPath.test_02_path_error_fix_from_list)
        (TestAltPath.test_05_path_error_fix_from_list_changed)
        (TestAltPath.test_06_path_error_fix_from_list_fails): self.session
        is destroyed in tearDown, so there's no need to do it in a test
        case.

        * Thuban/Model/load.py (SessionLoader.open_shapefile): Remove a
        debug print

2004-12-13  Bernhard Herzog  <[email protected]>

        * Extensions/svgexport/test/test_svgmapwriter.py
        (TestDrawSplines.setUp): Do not use super with the unittest
        classes because in Python 2.2 they're still old-style classes.

2004-12-13  Frank Koormann <[email protected]>

    Alternative Path feature: When loading a (moved) session where 
        shapefiles cannot be found, ask the user. Use the specified path 
        if further shapefiles are missing. However, ask the usr for confirmation 
        in such cases.

        * test/test_load.py (TestAltPath): New, tests for alternative path feature
        in load_session()
        (Shapefile_CallBack): Helper, implements controllable callback.

        * Thuban/UI/application.py (ThubanApplication.OnInit): 
        Added "alt_path" to self.path

        callback similar to db_connection_callback.
        (ThubanApplication.run_alt_path_dialog): New, implementaion of
        shapefile_callback. In addition to raising the dialog the control of
        self.path('alt_path') is implemented here.

        (SessionLoader.open_shapefile): Open shapefile, eventually with 
        alternative path. This wrapps the "theSession.OpenShapefile(filename)" 
        formerly used in start_fileshapesource()/start_layer().
        (SessionLoader.start_fileshapesource): Call open_shapefile().
        (SessionLoader.start_layer): Call open_shapefile().
        (load_session): Added shapefile_callback.

        * Thuban/UI/altpathdialog.py: New, implements dialogs for alternative path
        feature (search / check).
        
        * Doc/manual/thuban-manual.xml: Added documentation of new feature.

2004-12-11  Bernhard Reiter <[email protected]>

         svgexport 0.9.2: Point size supports for maps.

        * Extensions/svgexport/svgmapwriter.py: Added import of SHAPETYPE_POINT
        (def draw_point_shape): new parameter size defaults to 2 as before.
        (draw_shape_layer_incrementally): Moved draw_func log line higher.
        Added draw_func call with size when dealing with a point layer.

        * Extensions/svgexport/__init__.py: bumped version to 0.9.2.
        
2004-12-11  Bernhard Reiter <[email protected]>

        Made sure that newlines are inserted in the svg path d attributes
        to raise the chance that the line length will be below 255 characters,
        as recommended by REC SVG 1.1 in section 8.3.1.

        * Extensions/svgexport/svgmapwriter.py(DrawPolygon):
        Adding \n before L's and changed whitespace handling.

        * Extensions/svgexport/test/test_svgmapwriter.py:
        Adapted tests to new whitespace handling of DrawPolygon.

2004-12-11  Bernhard Reiter <[email protected]>

        * Doc/technotes/coding_guidelines.txt: easy typo fixed. 

        * Extensions/svgexport/test/test_svgmapwriter.py:
        Removed test_drawbezier in favour of new test_drawspline3 and 
        test_drawspline4 within new class TestDrawSplines(TestVirtualDC).
        All only to test DrawSpline.

        * Extensions/svgexport/svgmapwriter.py(DrawSpline):
        New implementation now really using the strange algorithm of
        xfig 3.1's approximated splines and its conversion to postscript
        with one twist: SVG can do quadratic beziers, so skipped translation
        to cubic beziers.
        (TestWithDC): Typo in comment fixed.

2004-12-09  Martin Schulze  <[email protected]>

        * Thuban/Model/classgen.py: Added missing character encoding

        * Extensions/wms/properties.py (OpenWMSProperties): removed

        * Extensions/wms/parser.py (WMSCapabilitiesParser.error): Dropped
        support for get_srs_discrepancies() since there are no
        discrepancies anymore (was a thinko)

        * Extensions/wms/layer.py (WMSLayer.GetMapImg): Improved graphic
        format priority now that more formats are supported globally by
        the render engine. 

2004-12-08  Silke Reimer <[email protected]>
        * Extensions/ogr/ogrshapes.py: Substituted ogr-method CloseRings
        because it is not available in all versions of ogr

2004-12-08  Bernhard Reiter <[email protected]>
        * Extensions/ogr/__init__.py: Added empty __init__.py to heal 
        global tests until a real one is commited.

2004-12-07 Nina Hüffmeyer <[email protected]>

        * /Extensions/ogr/: Adding a new extension to read shapefiles with
        ogr. It is planned to add other vector formats.

        executed.

2004-12-07  Bernhard Reiter <[email protected]>

        * Extensions/svgexport/test/test_svgmapwriter.py:
        Added test_drawbezier() to test DrawSpline().

        * Extensions/svgexport/svgmapwriter.py(DrawSpline):
        Really implemented bezier drawing.

        * Extensions/svgexport/__init__.py: Bumped version of svgexport
        to 0.9.1 because now the legend examples lines styles 
        will be drawing with beziers.

2004-12-05  Martin Schulze  <[email protected]>

        * Thuban/UI/renderer.py (raster_format_map): Added PNG, TIFF and
        GIF as supported bitmap image formats (helpful for the WMS extension)

2004-11-30  Martin Schulze  <[email protected]>

        * Extensions/wms/test/test_ogclib.py (TestOGCLib.test_compareURLs):
        Improved the test for the internal compare method

2004-11-27  Jan-Oliver Wagner <[email protected]>

        * Thuban/UI/about.py (About.__init__): Added
        Norbert Solymosi for hungarian translation and Ole Rahn

        to Experimental menu.

        * Extensions/svgexport/test/test_svgmapwriter.py: Fix to have
        the test run correctly even if the extension is a package.
        Also removed the "import Thuban" which makes no sense.

        * Extensions/svgexport/__init__.py: Fix to have the extensions'
        test module also be executed from the global test routine.
        This is done by looking for the absense of the DISPLAY variable.

        * Extensions/svgexport/maplegend.py: Moved the menu entry from Extensions
        to Experimental menu since this module has yet not reached a stable
        status (ie. 1.0).

2004-11-22  Bernhard Reiter <[email protected]>

        * Extensions/svgexport/svgmapwriter.py:
        Added verbose variable and some logging depending on it.
        (class VirtualDC(XMLWriter)): Minor improvement in the polygon loop, 
        because counting i is not necessary.
        (class Pen, class Brush): Added simple __str__ methods.
        (SVGRenderer.draw_polygone_shape): Fix #2698 (transparent polygons are
        not exported to svg file) Note: holes still unhandled.

        Now the hit test considers the size of point symbols.

        * Thuban/UI/viewport.py (ViewPort._hit_point): Added optional parameter
        'size' defaulting to the previously fixed value 5.
        Extended doc-string.
        (Viewport._find_shape_in_layer): Resolved FIXME regarding flexibility
        for symbols.
        Now the size of the largest point symbol is determined to find out
        about whether the point has been hit.
        This fixes the problem that only clicks inside a fixed distance of
        5 where found.

2004-11-17  Jan-Oliver Wagner <[email protected]>

        Another open issue fixed regarding sizeable symbols: correct rendering of
        selected symbols.

        * Thuban/UI/renderer.py (ScreenRenderer.draw_selection_incrementally):

        the size attribute.

        * Thuban/UI/classifier.py (ClassDataPreviewer.Draw): Added doc-string.
        Also, now there is a return value that indicates whether the drawing
        size exceeded the given rect extent and if so the new extent.
        Finally, point objects are drawn depending on the size. If either
        the width or height is exceeded, the new extent is returned.
        (ClassRenderer.Draw): Now when calling the previewer drawing function,
        evaluate the return value and, if not None, adapt the grid widget size

        both provided layer classes/types.

        * Thuban/UI/mainwindow.py (MainWindow.OpenLayerProperties): The
        map can be retrieved through the parent which is passed to the
        constructor anyway and doesn't require an argument of its own,
        required for the unification of arguments for general use through
        properties-dialog selector.
        (MainWindow.OpenOrRaiseDialog): Move the logic for checking
        whether a dialog is already opened (and raising it to the users

        More fixes to svgexport to make used ids unique and
        conforming to XML's Name production. 

        * Extensions/svgexport/test/test_svgmapwriter.py: Added new tests
        test_xml_id_constraints(), test_make_ide_nosetbaseid() and
        test_make_id_nonintegersetid().  Switched SetID and SetBaseID.
        Added Bernhard R. as author.
        * Extensions/svgexport/svgmapwriter.py (make_id): Using "_" as
        concatenation char now (makes test_make_ide_nosetbaseid() valid).
        Also transform second id part with "%d" and catch the TypeError
        to raise SVGMapWriterError (making test_make_id_nonintegersetid() ok).
        Corrected typo inBernhard's author line.
        (SetBaseID): Return the transformed base id. Transform characters
        which are not alnum() or in ".-_" to binascii.b2a_hex(). Added
        import binascii. If to be set string starts with "xml" or so, add "t".
        (draw_shape_layer_incrementally): use the returned value of SetBaseID
        for used_baseids checks.

2004-07-28  Jan Schüngel  <[email protected]>

        * Extensions/umn_mapserver/mapfile.py(MF_Metadata): Changed all class
        functions. Now all metadata will handle by the function and its not
        needed to initialize it from outside. Therefor the associated mapobj 
        will be stored in the Metadata Object. So we can use the special
        functions from the associated mapobj to get the Metadata.
        Therefor all initialization code for the metadata is removed from the
        other classes.
        (MF_Layer): Added a function to get the metadata object. 
        (MF_Map): Added a function to set the mappath, the path where
        the mapfile ist stored.

        * Extensions/umn_mapserver/mf_export.py(thuban_to_map): Changed the code
        to set the extent in the mapfile. Now the code is set by the displayed
        data in the Thuban-view.
        (export_mapfile): The shapepath is now set empty, until relative
        pathnames are supported.

        * Extension/umn_mapserver/mf_handle.py: Added a dialog to handle
        metadata. Yet only mapfile metadata are supported. Layer and class
        supported are not implemented.
        Added a dialog to handle layer informations. The dialog only shows the
        selected layer at the moment.

        * Extensions/umn_mapserver/mf_import.py(import_mapfile): Changed the
        code for setting the extent in thuban. Now the extent is set to the
        given extent from the mapfile. 
        Fixed a logical mistake. Now the extent is set when realy a layer is
        loaded, and not if one is selected to load.

        * Extensions/umn_mapserver/sample/iceland.html: Added code to zoom and
        move the shown map in the browser.

        * Extensions/umn_mapserver/sample/iceland.map: Added a new metadata
        line to the mapobj and added metadata to the political layer.

        * Extensions/umn_mapserver/test/test_mapserver.py: Changed the test
        for Metadata.

2004-07-26  Martin Schulze  <[email protected]>

        (SimpleViewPortTest.test_init_with_size): Add some VisibleExtent()
        tests.
        (SimpleViewPortTest.test_visible_extent): New. The real test for
        VisibleExtent()

2004-07-22  Bernhard Herzog  <[email protected]>

        * test/test_viewport.py: Use support.run_tests as the main
        function when running asa script.

2004-07-22  Jan Schüngel <[email protected]>

        * Extensions/umn_mapserver/mf_export.py: Added "import os"
        Removed the old "import Thuban.UI.mainwindow" code.
        (tbextent_to_map): Removed the extra function and at the code direct
        to "thuban_to_map" function.
        (write_creatorcomment): Added. Now a short comment is added to the
        beginning of an generated mapfile.
        (export_mapfile): Now the Path and filename are saved in to variables,
        and not together in one variable. This is needed for the new
        write_creatorcomment function.
                
        * Extensions/umn_mapserver/mf_import.py (import_mapfile): Added the
        import module "re". Also added Range and the ClassGroupRange import 
        from Thuban. Both are needed for the new range expression import.
        (create_rangeexpression): Added. Creates a Range Expression in Thuban
        style from a given mapfile expression.
        (added_rasterlayer): Make some small code changes. The shapepath is
        now stored in an extra variable and the clazz_name is set empty if no
        class name set in the mapfile.
        Changed the Error message for Range Expressions, becaus the new
        function create a error string which will be shown in the dialog.

        * Extensions/umn_mapserver/test/test_mapserver.py: Added a test for the
        range expression import.

2004-07-21  Jan-Oliver Wagner <[email protected]>

        * Extensions/umn_mapserver/README: Added hint that
        installation as root can be avoided. Removed all tabs.

        (ViewPortTest.test_changing_map_projection): Check that changing
        the projection of an empty map shown in a viewport doesn't lead to
        exceptions in the viewport's handler for the
        MAP_PROJECTION_CHANGED messages

        * Thuban/UI/viewport.py (ViewPort.map_projection_changed): Only
        try to keep the same region visible when the map actually contains
        something

2004-07-15  Jan Schüngel <[email protected]>

        * Extensions/umn_mapserver/mapfile.py: Added a function to get the
        mappath directly from the mapobj. Is needed because of the changes 
        in mf_import.py.
        (MF_Layer.add_thubanclass): Added a new comment.
        (MF_Map.set_extent): Fixed a bug with exporting empty mapobj. If the
        mapobj is empty there is no extent get from thuban an so no one can
        set to th mapobj.
        
        * Extensions/umn_mapserver/mf_import.py (import_mapfile): Updated
        the discription. 
        Split the funktion in to three smaller ones. The new functions are 
        add_rasterlayer, add_polygonlayer and select_layer2import.
        Removed the mapfilepath and filepath initialisation, because its know
        include in the new functions.
        Now nothing will be imported if cancel is pressed in the
        layer choice dialog.

2004-07-14  Jan Schüngel <[email protected]>

        * Extensions/umn_mapserver/mapfile.py: Added ClassGroupDefault to
        import.
        (MF_Symbolset): Removed the extra variable for numsymbols.
        (MF_Class.__init__): Added a comment to the exception clause.
        Removed the extent init, because it was not needed anymore.
        (MF_Layer.add_thubanclass): Added the code to set the class name to
        the expression value from thuban if no label is defined. 
        Added the code to export Range expressions from thuban to the mapfile.
        (MF_Map.set_extent): Removed the exception and replace it by some if
        code. If the size of a map is not defined the size will be set to 1,1.
        This is necessary because if the extent is set, mapscript checks if
        the size is greater than zero.
        (MF_Web): Added the get and set function for the template.

        * Extensions/umn_mapserver/mf_export.py: Added the function to check
        if a mapobject exists and used it to set the status of the menu items.
        If no mapfile exists the settings could not be edditied. 
        Define after which menuitem the exportitem will include.
        
        * Extensions/umn_mapserver/mf_handle.py: Removed the import 
        Thuban.UI.mainwindow clause, because it is not needed.
        Added the command Refresh() to all "OnChangeColor()" functions,
        because the color preview window was not updated on a color change.
        Added the function to check if a mapobject exists and used it to set the
        status of the menu items. If no mapobject exists the settings could not
        be edditied.
        (Map_Dialog): Moved the imagetype selector from the
        Outputformat_Dialog to Map_Dialog and removed Outputformat_Dialog.
        (Web_Dialog): Removed the name label and added the template textbox.

        * Extensions/umn_mapserver/mf_import.py (import_mapfile): Replace
        the exception handling on loading the layers by an if statement. It
        is not necessary to us the exception there.
        The Filepath creation now use os.path.join to build the path.

        * Extensions/umn_mapserver/test/test_mapserver.py: Moved the testMap
        definition from global to the setUp function. Now the testMap will
        initialize new on each test.

        * Extensions/umn_mapserver/sample/iceland.map: Include three new
        classes in the Line Layer, to test logical Expressions.
        Set the status of the class "Point9" in the Point Layer to off
        
2004-07-13  Bernhard Herzog  <[email protected]>

        * Thuban/UI/baserenderer.py
        (BaseRenderer.render_map_incrementally): Fix a logic bug in the
        optimization that tries not to draw layers under a raster layer.
        The bug was harmless.  All it effectively did was to produce The a
        strange messages about not being able to draw Layer instances for
        all vector layers below a raster layer which would be invisible
        anyway because the raster layer currently always covers the entire
        window

2004-07-08  Jan Schüngel <[email protected]>

        * Extensions/umn_mapserver/mapfile.py: Added code to generade and get
        a list of supported outputformats. This formats are not alle supported
        because there is no possibility to get the outputformat without the
        name known. Make some formal changes to the code.
        (MF_Map.set_name()): Fixed a bug if the name is None.

        * Extensions/umn_mapserver/mf_handle.py: Removed the image_type import
        statement, because its not needed anymore. The Outputformat is now
        given as string from the object. Make some formal changes to the code.

        * Extensions/umn_mapserver/test/test_mapserver.py: Added new test for
        most of the new setting which were added during the last changes.
        Removed the MF_Size Test.
        
        * Extensions/umn_mapserver/test/test.map: Added a new class to the
        cultural Layer to test expressions and the the status of that layer
        from on to default.
        Changed the data path the the correct Thuban Data

        and line Obj and add the scalebar_status_type, scalebar_style_type and
        scalebar_position_type.
        Added the symbol- and symbolsetObject (MF_Symbol,MF_Symbolset). The
        are only used to create a Symbol like the circle in Thuban.

        * Extensions/umn_mapserver/mf_export.py: Added MF_Symbol to import
        from mapfile. Added a function to create a circle object like the one
        from thuban if no one exists.
        
        * Extensions/umn_mapserver/mf_handle.py: All colors are now set when
        press ok in the assosiated dialog and not at the end of the
        colordialog.
        Added the Dialog for the Scalebar.
        (Label_Dialog): Added the offset option

        * Extensions/umn_mapserver/mf_import.py: Added code to import the
        status of the Classes.
        Fixed a bug with the projection. Now the to_meter parameter will be
        added to the Projection only if it doesn't exists. 

2004-07-01  Jan Schüngel <[email protected]>

        Added the functionality to handle the content thuban is not
        able to handle directly.

        * Extensions/umn_mapserver/mf_handle.py: New. This module extents
        Thuban with the possibility to edit the mapfile content.        
        
        * Extensions/umn_mapserver/mf_import.py: Added the possibility
        to import mapfiles without any layer selected. So it is possible 
        to edit the other settings in a mapfile.
        (import_mapfile): Added code to use the editing functions.
        Added the possibility to import the projection to a layer if one
        is defined.
        Status settings (On,Off) will now set in thuban (visible, invisible).
        fixed a bug with with classnames. If no classname is set in mapfile
        the value in Thuban will set to the expression.
        
        * Extensions/umn_mapserver/mf_export.py(export_mapfile): Added the
        possibility to save a new mapfile or use the old one which is 
        imported or new created.
        Added code to use the editing functions.
        Remove some not needed import statements

        * Extensions/umn_mapserver/mapfile.py: Added new types which are
        need for the editing functions.
        Added needed set-functions for the editing functions.
        Added the possibility to export rasterimages.
        Added new classes (MF_Web, MF_Label, MF_Legend, MF_Symbol,
        MF_SymbolSet). MF_Symbol and MF_SymbolSet are not needed at the
        moment.
        (MF_Class.set_thubanstyle): Now point layers will set to a default
        symbol to show a circle in mapserver and not only a 1px dot.
        (MF_Style.__init__): Fixed a bug with the color. Color was not set
        correct before.
        (MF_Size): Removed, because it is not needed.
        
        * Extensions/umn_mapserver/README: Added the hints to use the
        export and editing functions, too.

        * Extensions/umn_mapserver/sample/iceland.map: Added the
        new parameter "UNITS METERS".
        Change the political layer to status OFF.

        * Extensions/umn_mapserver/sample/README: Added some
        more details to setup the sample in the MapServer.
        
2004-06-26  Bernhard Reiter <[email protected]>

        * Extensions/svgexport/test/test_svgmapwriter.py: 
        Removed class VFile and used standard StringIO instead.

2004-06-23  Jan Schüngel  <[email protected]>

        Add the export function to the umn_mapserver extension.

        * Extension/umn_mapserver/mf_export.py: New. This module extents
        Thuban with the possibility to export the Thuban content.

        * Extensions/umn_mapserver/mapfile.py: Expand the classes to use
        with the export module. Especially added the possibility to
        add thuban objects directly to the map objects.

        * Extensions/umn_mapserver/mf_import.py: Removed the wxCHANGE_DIR,
        because of the hint from Bernhard Herzog.
        Corrected the handling of absolute pathnames.
        Changed the Text of the Menu-Item, now the beginning is upper case.

        * Extensions/umn_mapserver/README: Added the --with-tiff statement.

2004-06-16  Jan Schüngel  <[email protected]>

        Add a sample and make some changes.

        * Extension/umn_mapserver/mf_import.py: Changed the wxPython.wx
        import from * to explicit used statements. Changed the 
        Thuban.UI.mainwindow import phrase, too.
        (import_mapfile):Corrected a clerical mistake.
        Added wxCHANGE_DIR in OpenFile Dialog.
        Added a MultipleChoiceDialog, to select the layers to load from
        mapfile into thuban. Thereby the projection is only set if one layer
        is selected.
        Added the possibility to handle relative pathnames which uses 
        up-level references.
        Removed some doubled code.
        Corrected an error with integer values used as label in thuban
        ClassGroup.
        
        * Extensions/umn_mapserver/sample: New.

        * Extensions/umn_mapserver/sample/README: New. Describes the
        usage of the sample files.

        * Extensions/umn_mapserver/sample/iceland.map: New. This is
        a suitable .map-file for the iceland data. 

        * Extensions/umn_mapserver/sample/index.html: New. The template
        for the mapfile.  

        * Extensions/umn_mapserver/sample/iceland.html: New. Initialisation
        file for the Iceland Application on web.

        * Extensions/umn_mapserver/README: Corrected a inaccuracy and added
        some details.

        * Extensions/umn_mapserver/test/test_mapserver
        (mapserver_import_Test_generalClasses.test_MF_Color):
        Corrected the thubancolor test.

2004-06-15  Jan Schüngel  <[email protected]>

        * Extensions/umn_mapserver/README: New. Install instruction.

2004-06-14  Bernhard Reiter <[email protected]>

        * libraries/thuban/cpl_mfile.h: Added copyright header.

        * libraries/thuban/ cpl_mfile.cpp, cpl_mfile.h: Added non-protecting
        Free Software License so that it is most useful with gdalwarp 
        and bmpdataset.

2004-06-14  Bernhard Herzog  <[email protected]>

        * Thuban/UI/multiplechoicedialog.py (__version__): Add missing
        import of wxPython.wx itself (as opposed to the contents of
        wxPython.wx).  For some reason wxPython.wx is available as
        wxPython.wx.wx in at least some 2.4 releases.  Fixes RT#2482
        wrt. wxPython 2.4.

2004-06-10  Jan Schüngel  <[email protected]>

        Initial version of new extension "umn_mapserver".  This extension aims
        to manage configuration for the UMN MapServer application.  This
        inital version just imports the .map-files and displays all, Thuban is
        capable of.

        * Extensions/umn_mapserver, Extensions/umn_mapserver/test: New.

        * Extensions/umn_mapserver/test/README: New. Describes how to run the
        tests.

        * Extensions/umn_mapserver/test/test.map: New. This is a test
        .map-file for automated tests of the umn_mapserver extension of
        Thuban.

        * Extensions/umn_mapserver/test/test_mapserver.py: New. Tests for
        UMN Mapserver classes.

        * Extensions/umn_mapserver/__init__.py: New. Init to make this
        directory a package.

        * Extensions/umn_mapserver/mapfile.py: New. Classes to represent
        '.map'-file objects.

        * Extensions/umn_mapserver/mf_import.py: New. This module extends
        Thuban with the possibility to handle UMN MapServer mapfiles.

2004-06-03  Bernhard Herzog  <[email protected]>

        * Thuban/Model/layer.py (Layer.TreeInfo): Convert the bounding box
        to a tuple before using it as arguments to the % operator.  This
        fixes the formatting issue filed in RT#2239 on 2004-01-13 and
        reported today on thuban-list by Jan Schüngel

        * test/test_layer.py (TestLayerModification.setUp): Save the
        filename as an instance variable so we can refer to it in tests
        (TestLayerModification.test_tree_info): Uncomment this method
        again and make it work.  This tests for the formatting issue
        filed in RT#2239 on 2004-01-13

2004-05-28  Bernhard Herzog  <[email protected]>

        * Thuban/UI/baserenderer.py: Fix some typos.

2004-05-18  Jan-Oliver Wagner <[email protected]>

        * Extensions/gns2shp/gns2shp.py (gns2shp): Fixed a bug
        by increasing a field size.

2004-05-17  Bernhard Herzog  <[email protected]>

        Update to newest shapelib and get rid of Thuban specific
        extensions, i.e. use the new DBFUpdateHeader instead of our
        DBFCommit kludge

        * libraries/shapelib/shpopen.c: Update to version from current
        shapelib CVS.

        * libraries/shapelib/shapefil.h: Update to version from current
        shapelib CVS.

        * libraries/shapelib/dbfopen.c: Update to version from current
        shapelib CVS.
        (DBFCommit): Effectively removed since shapelib itself has
        DBFUpdateHeader now which is better for what DBFCommit wanted to
        achieve.  
        We're now using an unmodified version of dbfopen.

        * setup.py (extensions): Add the HAVE_UPDATE_HEADER macro with
        value '1' to the Lib.dbflibc extension.  This simply reflects the
        shapelib and pyshapelib updates

2004-05-16  Jan-Oliver Wagner <[email protected]>

        Finished introduction of Menu.FindOrInsertMenu.

        * Extensions/drawshape/drawshape.py: Add the command
        to the experimental menu additionally to the toolbar.

        * Extensions/svgexport/svgsaver.py: Use FindOrInsertMenu() instead of
        finding menu on its own.

        * Doc/manual/thuban-manual.xml: updated sample file
        to use FindOrInsertMenu().

        * Examples/simple_extensions/hello_world.py: Use FindOrInsertMenu()
        instead of finding menu on its own.

2004-05-11  Jan-Oliver Wagner <[email protected]>

        * test/test_menu.py (MenuTest.test): Added testing
        of method Menu.FindOrInsertMenu.

2004-05-10  Jan-Oliver Wagner <[email protected]>

        Introduce and use Menu.FindOrInsertMenu.

        * Thuban/UI/menu.py (Menu.FindOrInsertMenu): New. Find a
          given menu or, if not found, insert it.

        * Extensions/bboxdump/bboxdump.py, /Extensions/gns2shp/gns2shp.py,
        /Extensions/importAPR/importAPR.py, Extensions/profiling/profiling.py,
        /Extensions/wms/wms.py: Use FindOrInsertMenu() instead of finding
        menu on its own.

2004-05-06  Jan-Oliver Wagner <[email protected]>

        Introduce a abstract ColorDialog class and remove
        and outdated file.

        * Thuban/UI/proj4dialog.py: Removed. It is has been
        replaced by projdialog for quite a while and is not used
        anymore.

        * Thuban/UI/colordialog.py: New. Abstraction for color selection
        dialog(s).

        * Thuban/UI/classifier.py (SelectPropertiesDialog.__GetColor):
        Now calls the abstract ColorDialog instead of wxColourDialog.
        This also removed the dependency to Color class conversion
        from this function.

2004-05-04  Frank Koormann  <[email protected]>

        * Extensions/bboxdump/__init__.py: Fixed string left over from 
        copying.

        * Extensions/bboxdump/bboxdump.py (bboxdump): 
        Use layer.ShapeStore().AllShapes() to loop over shapes instead of 
        xrange(layer.NumShapes()). Compile the bboxmessage from a list 
        of formatted outputs (string.join) instead of appending to the
        message. Two progress bar dialogs to report progress on the sometimes
        lenghty processing.

2004-04-22  Frank Koormann  <[email protected]>

        New Extension to dump bounding boxes of all shapes of the selected 
        layer. An optional column can be specified to group the objects, 
        in this case the bounding box is a union of the separate boxes.
        Dump can be displayed in a ScrolledMessageDialog or written to file. 
        The Extension is simply a combination of available and well tested
        Thuban functionality.

        * Extensions/bboxdump/__init__.py: New: Init to make this
        directory a package.

        * Extensions/bboxdump/bboxdump.py: New: Dump bounding boxes of 
        all shapes of the selected layer.

2004-04-22  Jan-Oliver Wagner <[email protected]>

        * Thuban/UI/classgen.py (GenUniquePanel.__init__): Fixed two
        strings to be i18n now.

2004-04-18  Jan-Oliver Wagner <[email protected]>

        Changing popup menu of legend from direct building
        to using the Menu construction as used for the mainwindow.

        * Thuban/UI/mainwindow.py: New method commands: layer_to_top,
        layer_to_bottom, layer_visibility
        (MainWindow.LayerToTop): New. Put current layer to the top.
        (MainWindow.LayerToBottom): New. Put current layer to bottom.
        (MainWindow.HideLayer, MainWindow.ShowLayer, _has_visible_map):
        Replace 1,0 by True, False.
        (MainWindow.ToggleLayerVisibility): New. Toggle visibility of
        current layer.
        (MainWindow.LayerShowTable): Removed raising of dialog.
        (_has_selected_layer_visible): New. Support function.

        * Thuban/UI/legend.py: ID_POP_xxx: removed.
        (LegendPanel.__init__): Removed EVT_MENU bindings.
        (LegendTree._OnRightClick): Replace direct creation of
        menu via wx Classes by applying the menu definition
        as of Menu class of menu.py.
        
2004-04-16  Jan-Oliver Wagner <[email protected]>

        * Thuban/UI/exceptiondialog.py (ExceptionDialog.dialog_layout): Improved
    button string to stronger clearify that Thuban will be closed when hitting
        the button.

        * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Added docstring.
        Now for layers without a ShapeStore a corresponding message is given
        to the user, that this layer has no table to show.

2004-04-15  Martin Schulze  <[email protected]>

        * Extensions/wms/layer.py (WMSLayer.setWMSFormat): Need to
        recalculate the format for the internal render engine as well.

        * Extensions/wms/properties.py (wmsProperties): First start for a
        properties dialog.  It's functional for a first selection of
        layers, but still has some weired wxWidgets/GTK problems but
        beautification can be done later.

        * Extensions/wms/layer.py: Added more documentation
        (WMSLayer.getFormats): New: Return list of supported image formats
        by the WMS server
        (WMSLayer.getLayers): New: Return the list of layer names
        supported by the WMS server
        (WMSLayer.getLayerTitle): New: Return the title of the named layer
        (WMSLayer.getWMSFormat): New: Return the image format that is used
        for WMS GetMap requests
        (WMSLayer.setWMSFormat): New: Set the image format that is used
        for WMS GetMap requests
        (WMSLayer.__init__): Move away from using only one layer to using
        a list of layers (unsorted at the moment, though).
        (WMSLayer.getVisibleLayers): New: Return the list of names for all
        visible layers
        (WMSLayer.setVisibleLayers): New: Set the list of names for all
        visible layers

        * Extensions/wms/wms.py: Moved the WMS layer into layer.py in
        order to establish a clean structure.

        * Extensions/wms/layer.py: Moved the WMS layer into a file on its
        own in order to establish a clean structure.

2004-04-13  Martin Schulze  <[email protected]>

        * Extensions/wms/parser.py (WMSCapabilitiesParser.grok): Added
        support for oldstyle (WMS 1.0 apparently) image format
        specification.

        * Extensions/wms/wms.py (WMSLayer.calcFormat): Reduce the list of
        supported graphic formats back to JPEG and BMP, PNG and others are
        too *cough* experimental...  Sorry, I meant to filter this out
        before I committed this part.  This should make the WMS extension
        run from CVS again.
        (wms_dialog): Reset an empty URL to None so that the subsequent
        program can depend on this, since the dialog will indeed return an
        empty URL, causing another declaration of love by Python.

        * Extensions/wms/parser.py (WMSCapabilitiesParser.getLayerBBox):
        Whenever a native BoundingBox request cannot be fulfilled, check
        whether the requested SRS is EPSG:3426, in which case return the
        LatLonBoundingBox values.

        * Extensions/wms/test/test_parser.py
        (TestWMSCapabilitiesParser.test_LayerSRS): Added a test for
        ignoring AUTO:* SRS.
        (TestWMSCapabilitiesParser.test_LatLonBoundingBoxes_as_bboxes):
        Added another test method to test whether the LatLonBoundingBox
        values will be returned if BoundingBox values are requested with
        SRS set to EPSG:3426.

        * Extensions/wms/parser.py (WMSCapabilitiesParser.peekLayers):
        Added rudimentary support for non-EPSG SRS, i.e. ignore them for
        the moment by placing them into a variable which is currently
        unused.  Also test whether the EPSG SRS is numerical as it should
        be and add an error message if it is not.

        * Extensions/wms/test/sample.xml: Added AUTO:* SRS since they
        appear in the real world as well.  Since we cannot handle them yet
        (OGCLib can't either), we will ignore them for the moment.

        * Extensions/wms/parser.py: Use a variable for denoting the sample
        filename
        (WMSCapabilitiesParser.peekLayers): Added support for error
        messages during grok().  They will be aggregated in an array and
        may be displayed later.  We may have to add a classification
        "Warning" and "Error" to this.  That requires more experience,
        though, since not every error may be lethal.

        * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Raise the
        ShowTable() dialog/frame when the user attempts to display it
        while it has been opened before already and not closed again.

2004-04-11  Martin Schulze  <[email protected]>

        * Extensions/wms/infodialog.py: Adjusted the class documentation

        * Extensions/wms/wms.py (WMSLayer.__init__, WMSLayer.GetMapImg):
        Switch to using Thuban{Begin,End}BusyCursor instead of the pure
        wxWidgets variants.
        (WMSLayer.__init__): The epsg_id variable is named top_srs now.

        * Extensions/wms/infodialog.py: Added an information dialog that
        will display various information about the WMS current resource,
        so that additional information such as the title, the abstract,
        fees and access constraints can be displayed for the user if they
        are documented in the WMS XML.

2004-04-10  Martin Schulze  <[email protected]>

        * Extensions/wms/parser.py (WMSCapabilitiesParser.grok): Adjusted
        string handling.  It's "foo".lower() and not lower(foo) without
        lower imported from strings or something.

        * Extensions/wms/wms.py (WMSLayer): Incorporated WMSCapabilities
        from capabilities.py and parser.py.  Implement priority list for
        supported graphics formats, take care of wbmp != bmp.  PNG, TIFF
        and GIF are supported here, but not yet by main Thuban.  Hence,
        support for them may be removed later.  Special contribution to
        usability: get wxWidgets to change the cursor when we're waiting
        for data from the network so the user won't start to worry.  This
        causes a redrawing error/warning, though.

        * Extensions/wms/parser.py (WMSCapabilitiesParser.grok): Unlink
        the DOM object.

2004-04-01  Martin Schulze  <[email protected]>

        * Extensions/wms/capabilities.py: Adjusted documentation
        (WMSCapabilities.__init__): Improved documentation, fixed syntax
        (WMSCapabilities.saveCapabilities): Only catch IOError when
        handling files
        (WMSCapabilities.loadCapabilities): Only catch IOError when
        handling files
        __main__: corrected variable naming
        (WMSCapabilities.fetchCapabilities,loadCapabilities): Make this
        class a specialisation of WMSCapabilitiesParser as well.  Also
        execute grok() after loading or fetching capabilities, if that
        went well, so that subsequent calls can already access the data.
        (WMSCapabilities.getVersion): Export the used version of the
        GetCapabilities request, so we can use it for subsequent calls,
        i.e. for GetMap requests.
        (WMSCapabilities.fetchCapabilities): Added proper error handling
        when the GetCapabilities request failed, so that the surrounding
        program can act accordingly.

2004-03-30  Martin Schulze  <[email protected]>

        * Extensions/wms/parser.py (WMSCapabilitiesParser.getLayerSRS):
        Adjusted the getLayerSRS method to return the list of SRSes
        extracted from <SRS> elements instead of <BoundingBox> elements.
        Added a bit of documentation as well.
        (WMSCapabilitiesParser.checkLayerSRS): Removed integrity test
        since it was only implemented due to a misunderstanding.

        * Extensions/wms/test/test_parser.py
        (TestWMSCapabilitiesParser.test_LayerSRS): Adjust the tests to
        reflect the corrected interpretation of the standard: i.e. a layer
        does not have to define a BoundingBox for all SRSes it supports.
        Hence the <SRS></SRS> specification is authoritative, not the list
        of BoundingBoxes.
        (TestWMSCapabilitiesParser.test_BoundingBoxes): Added a new test
        to ensure None is returned for a non-existing SRS.
        (TestWMSCapabilitiesParser.test_grok): Removed test_grok method
        since it is not applicable anymore.  Listing more SRSes in <SRS>
        elements is valid according to the specs.

2004-03-26  Bernhard Reiter <[email protected]>

        * README: Nicer formatting of text. Improved descriptions.
        Reflected wxWidgets name change.
        
        * Thuban/UI/about.py: Extended copyright to 2004 and added
        information about the thuban-devel mailinglist.

2004-03-24  Martin Schulze  <[email protected]>

        * Extensions/wms/capabilities.py: Renamed the class to contain
        'WMS', also added a linebreak where required

        * Extensions/wms/parser.py: Finally added the XML parser for the
        GetCapabilities response.

        * Extensions/wms/test/sample.xml: Adjusted the sample file so that
        <SRS> elements match the <BoundingBox> elements, except for the
        layer 'beschriftung'.

        * Extensions/wms/test/test_parser.py: Encode non-ascii strings
        since Python uses unicode strings internally, otherwise
        comparisons will fail.  Removed tests for getLayerBBoxSRS() since
        the SRS will be calculated anyway and this method is obsoleted by
        getLayerSRS().  Denote SRS as strings and not as cardinal numbers.
        Move loading the sample file into the setUp method.  Added a test
        for finding the integrity problem in the sample response.
        Improved formatting.

        * Extensions/wms/domutils.py: Added convenience routines for
        handling of Document Object Model (DOM) nodes.

        * Extensions/wms/test/test_domutils.py: Added a test for the
        domutils module

2004-03-19  Martin Schulze  <[email protected]>

        * Extensions/wms/test/test_parser.py (TestWMSCapabilitiesParser):
        Moved path detection and adding into a module of its own,
        adjustpath, which exports thubandir as main Thuban directory.

        * Extensions/wms/test/test_ogclib.py (TestWMSLib): Moved path
        detection and adding into a module of its own, adjustpath, which
        exports thubandir as main Thuban directory.  Reorganised the
        module in order to support the SkipTest feature for Thuban test
        cases.

        * Extensions/wms/test/adjustpath.py: Moved path detection and
        adding into a module of its own.

2004-03-18  Martin Schulze  <[email protected]>

        * Extensions/wms/test/test_parser.py: Added another test for
        checking whether the WMS XML parser (to be implemented) returns
        the information we expect.  This requires a sample WMS WML file
        (sample.xml) which has been extracted from the frida server and
        "improved" manually.

        * Extensions/wms/test/test_ogclib.py: Added legacy code to add the
        main Thuban directory to the path in order to be able to import
        random modules.  Adjusted the PyOGCLib detection to reuse the
        information gathered.  Also added a note about the PYTHONPATH
        environment variable.

        * Extensions/wms/test/test_ogclib.py: The format specification is
        a mime-type, not a graphic format, hence image/jpeg wou ld be the
        proper format and not JPEG.  We'll also have to take care of the
        encoding of / as %2F.

2004-03-16  Martin Schulze  <[email protected]>

        * Extensions/wms/test/test_ogclib.py: Added a (hopefully)
        comprehensive test for the getMapURL method, built compare URLs
        according to the documentation in OGC 01-068r3

        * Extensions/wms/capabilities.py (WMSCapabilities): Added the
        class WMSCapabilities to manage capabilites, will incorporate
        parsing the capabilities response and provide details for other
        classes.

2004-03-12  Bernhard Herzog  <[email protected]>

        Support views in addition to normal tables in the postgis
        shapestore

        * Thuban/Model/postgisdb.py
        (PostGISShapeStore._fetch_table_information): Add a fallback for
        the case where the table name is not in the geometry_columns
        table.  This is usually the case for views.  Also, set
        self.shapestore here.
        (PostGISShapeStore.ShapeType): No need to query the database all
        the time.  The shape type is now determined in
        _fetch_table_information

        * test/postgissupport.py (PostgreSQLServer.new_postgis_db)
        (PostgreSQLServer.get_static_data_db, PostGISDatabase.__init__):
        New parameter to specify views.
        (PostGISDatabase.has_data): Also compare the views.  New views
        parameter

        PostGISShapeStore with a view
        (TestPostGISShapestorePointOIDAsGIDColumn.setUp): Pass the name of
        the geometry_column explicitly to test whether that works

2004-03-12  Bernhard Herzog  <[email protected]>

        Final step for explicit id/geometry columns: Loading and saving

        * Resources/XML/thuban-1.1.dtd: New.  Derived from thuban-1.0.dtd
        with the following changes:
        (dbshapesource): Two new attributes id_column and geometry_column

        paramters

2004-03-11  Bernhard Herzog  <[email protected]>

        Next step for explicit id/geometry columns: User interaction

        * Thuban/UI/dbdialog.py (ChooseDBTableDialog.__init__): Rework how
        the dialog is constructed. Add combo boxes to select id and
        geometry column.  Rename some instance variables.
        (ChooseDBTableDialog.GetTable): Return id and geometry column
        names

        shapestores.  Now supports views as well but is more PostgreSQL
        specific
        (PostGISConnection.table_columns): New. Somewhat experimental
        method to let the db dialogs provide lists of columns to users so
        that they can select id and geometry columns.
        (PostGISTable.__init__): The default value of the id_column
        parameter is now None it still means "gid" effectively, though.
        (PostGISTable.IDColumn): New introspection method to return a
        column object for the id column
        (PostGISShapeStore.GeometryColumn): New introspection method to
        return a column object for the geometry column

        * test/test_postgis_db.py
        (TestPostGISConnection.test_gis_tables_non_empty):
        Removed. Subsumed by the new:

        numbers given to ReadValue are ordinals.

2004-03-11  Bernhard Herzog  <[email protected]>

        Elimiate the requirement for PostGIS tables to have a column
        called "gid".

        * Thuban/Model/postgisdb.py (PostGISTable.__init__): New parameter
        id_column to specify which column to use to identify rows.  Also
        new instance variables id_column and quoted_id_column
        (PostGISTable.RowIdToOrdinal, PostGISTable.RowOrdinalToId)
        (PostGISTable.ReadRowAsDict, PostGISTable.ReadValue)
        (PostGISTable.SimpleQuery): Use the id column name provided to the
        constructor instead of "gid"
        (PostGISShapeStore.__init__): New parameter id_column analogously
        to PostGISTable.__init__.  This parameter is simply passed through
        to the base class constructor
        (PostGISShapeStore._create_col_from_description): Fix typo in
        doc-string
        (PostGISShapeStore.Shape, PostGISShapeStore.AllShapes)
        (PostGISShapeStore.ShapesInRegion): Use the id column name
        provided to the constructor instead of "gid"

        * test/postgissupport.py
        (PostgreSQLServer.get_default_static_data_db): New static table
        landmarks_point_id with an id column != "gid.  Update the comments
        a bit.

        doc-
        (upload_shapefile): New parameter gid_column to use a name other

        * test/test_postgis_db.py (TableTests): New.  Mixin-class
        containing all tests previously in TestPostGISTable.  The actual
        tests are the same but the code is a bit more configurable to
        allow for different id columns etc.
        (TestPostGISTable): Derive from TableTests now for the actual
        tests.
        (TestPostGISTableExplicitGIDColumn): New. Like TestPostGISTable

        (TestPostGISShapestorePointExplicitGIDColumn)
        (TestPostGISShapestorePointOIDAsGIDColumn): New classes derived
        from PointTests to test the explicit id_column parameter.  One
        tests with the name of the column holding the shape ids, the other
        uses PostgreSQL's OID column.  For the latter a number of methods
        have to be overwritten to make them independent of the actual id
        values.

        * libraries/thuban/wxproj.cpp (get_wx_version): New.  Return the
        version of wxWindows the module was compiled with so we can check
        that against the wxPython version.

        * Thuban/version.py (thuban_branch, thuban_release): New variables
        controlling which and how Thuban versions are shown.  See the
        comments for details.
        (verify_versions): Also check that the wx version that wxproj is
        compiled against matches that of the wxPython we use at runtime

2004-02-20  Bernhard Herzog  <[email protected]>

        * Extensions/wms/wms.py (epsg_code_to_projection): Use
        get_system_proj_file to read the epsg projections.  The old way
        depended on the current directory being the top Thuban directory.

2004-02-20  Bernhard Herzog  <[email protected]>

        * Extensions/svgexport/test/test_svgmapwriter.py

        Extensions/svgexport into a package.

        * Extensions/svgexport/svgmapwriter.py: Reorder the imports and
        doc-string a bit.  The doc-string must come first, otherwise it's
        not a doc-string.  The __future__ import must be the first thing
        after the doc-string.  Use only double quotes in doc-strings.
        Single quotes trip up emacs syntax highlighting if the text
        contains apostrophes.

2004-02-20  Bernhard Herzog  <[email protected]>

        * Extensions/svgexport/test/__init__.py,
        Extensions/svgexport/test/test_svgmapwriter.py: New. Initial test
        suite for svgexport

        * test/runtests.py (find_test_modules): New. Function with the
        module finding code from main.

        modules and take modules from Extensions.svgexport.test too.

2004-02-19  Bernhard Herzog  <[email protected]>

        * Thuban/UI/application.py (ThubanApplication.OnInit): Make sure
        the mainwindow has a reference to the map of the initial session.
        This fixes a bug introduced with the fix for RT#2245

2004-02-19  Bernhard Herzog  <[email protected]>

        * Extensions/svgexport/svgsaver.py,
        Extensions/svgexport/svgmapwriter.py,
        Extensions/svgexport/maplegend.py: Added again.  This time in the
        correct place.

        Fix for RT#2245

        * Thuban/UI/application.py (ThubanApplication.OnInit): Initialize
        instance variables before trying to create any windows.  Creating
        windows can start an event loop if e.g. message boxes are popped
        up for some reason, and event handlers, especially EVT_UPDATE_UI
        may want to access things from the application.
        (ThubanApplication.maps_changed): The mainwindow may not have been
        created yet, so check whether it has been created before calling
        its methods

        * Thuban/UI/view.py (MapCanvas.OnIdle): Only try to redraw if we
        have a map

2004-02-17  Bernhard Herzog  <[email protected]>

        extensions/svgexport/svgsaver.py,
        extensions/svgexport/svgmapwriter.py,
        extensions/svgexport/maplegend.py: Removed.  These files were in
        the wrong places or didn't work at all.

2004-02-16  Bernhard Herzog  <[email protected]>

        * Thuban/UI/view.py (MapCanvas.Export): Remove accidentally added
        line

2004-02-16  Bernhard Herzog  <[email protected]>

        * Thuban/UI/view.py (MapCanvas.Export): Avoid UnboundLocalError.

2004-02-15  Markus Rechtien  <[email protected]>

        to write a SVG map of a session.
        * Extensions/svgexport/maplegend: New. Writes a basic maplegend
        in SVG format for the current session.

2004-02-13  Bernhard Herzog  <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.AddDBLayer): When the layer
        can't be created, return immediately after displaying the error
        message.

2004-02-11  Bernhard Herzog  <[email protected]>

        Handle postgis tables with more than one geometry column.

        * Thuban/Model/postgisdb.py
        (PostGISTable._fetch_table_information): Delegate the creation of
        column objects to a different method so that we can extend that in
        derived classes
        (PostGISTable._create_col_from_description): New. Column object
        creation part of _fetch_table_information
        (PostGISShapeStore._create_col_from_description): New. Extend
        inherited method to handle geometry columns
        (PostGISShapeStore.__init__): New parameter geometry_column to
        specify which geometry column to use.  Optional but mandatory for
        tables with more than one geometry column

        the geometry column when looking for the srid
        (PostGISShapeStore.ShapeType): Also use the name of the geometry
        column when looking for the shape type

        * test/test_save.py (SaveSessionTest.test_save_postgis): Adapt
        NonConnectionStore to changes in the PostGISShapeStore

        * test/test_postgis_db.py
        (TestPostGISSpecialCases.test_shapestore_two_geom_cols): Test
        PostGISShapeStore with tables having two geometry columns.

2004-02-10  Bernhard Herzog  <[email protected]>

        Fix some postgis problems.  What remains to be done is real
        handling of SRIDs as they affect how reprojection is done

        * Thuban/Model/postgisdb.py (quote_identifier): Fix typo in
        doc-string
        (PostGISShapeStore._fetch_table_information): New. Extend
        inherited method to retrieve srid

        added (Thuban/UI/application.py:273)

2004-02-03  Frank Koormann  <[email protected]>
        
        First version of Portuguese (Brazilian) translation

        * po/pt_BR.po: New, translation of pot (2004-01-15 16:07+0300) for
        Brazilian Portuguese by Eduardo Patto Kanegae.

        Make Thuban remember path selections (at least for one application run).

        * Thuban/UI/application.py (Application.OnInit): Initialize path as a 
        attribute of application object. Path is a dictionary of
        strings, currently with the items "data" and "projection".

        tests to this

        * test/test_load.py (LoadSessionTest.filenames): With the new
        filename scheme the filenames in the tests should be
        understandable on all currently supported platforms so we turn
        this into an empty list because we don't have to normalize them
        anymore

2003-11-28  Bernhard Herzog  <[email protected]>

        * test/test_layer.py (TestLayer.test_arc_layer_with_projection):
        Add the ellipsoid to the projection since some Proj versions

        InverseBBox

        * Thuban/Model/layer.py (Layer.LatLongBoundingBox)

        InverseBBox to unproject bboxes

        source code.

2003-11-25  Bernhard Herzog  <[email protected]>

        (ShapefileStore.__init__): Factor opening the shapefile into a
        separate method (the new _open_shapefile). This makes the code a
        bit more readable but the real reason is that it makes some evil
        hacks easier. :-)

2003-11-24  Bernhard Herzog  <[email protected]>

        * Thuban/Model/load.py (SessionLoader.check_attrs): If no
        converter is specified for an attribute assume it's a string
        containing only Latin1 characters. Update doc-string accordingly.
        This change should fix many places where unicode objects might
        accidentally enter Thuban.

        * test/test_load.py (TestNonAsciiColumnName): New test to check
        what happens with column names in DBF files that contain non-ascii

        the commmand line
        (main): Add the --enable-attribute-editing flag.

        editing is enabled use the grid ctrl which allows editing of the
        values

        * Thuban/Model/transientdb.py (AutoTransientTable.write_record):
        New. Just delegate this to the underlying table.

2003-11-20  Bernhard Herzog  <[email protected]>

        Skip this test if run under non-posix systems since it only works
        there

2003-11-19  Bernhard Herzog  <[email protected]>

        * Thuban/Model/resource.py: Rework the way gdal support is
        determined so that we can give a reason in the about why gdal is

        reason for no gdal support

        anymore

        * test/test_table.py: Removed since the old interface it tests is
        gone.

        * test/runtests.py (main): The old table interface is gone and
        with it the deprecation warnings so remove the code that turns
        these warnings into errors

2003-11-19  Bernhard Herzog  <[email protected]>

        * test/test_table.py: Revert to revision 1.5 again. Changing the
        tests to use the new table interface is completely wrong since the
        whole purpose of the tests in this module is to test the old
        interface.

        MatchesParameters method

2003-11-18  Bernhard Herzog  <[email protected]>

        * Thuban/Lib/connector.py (Publisher): Introduce a new flag,
        _was_destroyed, to indicate whether an publisher instance has
        already been destroyed.

        been destroyed yet.

        (PostGISTable.UniqueValues, PostGISTable.SimpleQuery)
        (PostGISShapeStore.BoundingBox, PostGISShapeStore.Shape)
        (PostGISShapeStore.AllShapes, PostGISShapeStore.ShapesInRegion):
        Use quoted table and column names

        * test/test_postgis_db.py (TestPostGISSpecialCases)
        (TestPostGISIgnoredColumns): Rename the class to
        TestPostGISSpecialCases because that better describes the new

        test_unsupported_types because we need a more descriptive name now
        that there are more methods
        (TestPostGISSpecialCases.test_table_name_quoting)

        non-ascii characters unless an encoding is specified in the file.
        Therefore use \x escapes in the string literals for non-ascii
        characters.

2003-11-11  Bernhard Herzog  <[email protected]>

        * Thuban/Model/resource.py (get_system_proj_file): Add a filename
        parameter so that this function can be used for all proj files in
        Resource/Projections
        (DEFAULT_PROJ_FILE, EPSG_PROJ_FILE): New. Predefined filenames for
        get_system_proj_file

        * Thuban/UI/projdialog.py (ProjFrame.__init__): Instead of one
        ProjFile self.__sysProjFile use a dictionary of system ProjFile
        objects self._sys_proj_files
        (ProjFrame.build_dialog): Adapt to the new changes in the
        ProjectionList constructor. Add a check button to toggle whether
        EPSG projections are shown
        (ProjFrame._OnShowEPSG): New. Handler for the epsg check button
        events.
        (ProjFrame.load_user_proj, ProjFrame.load_system_proj): Only show
        the busy cursor if the files have not yet been loaded by the
        dialog.
        (ProjFrame.load_system_proj): Add a parameter for the name of the
        proj file. Maintain the dictionary of system projections
        self._sys_proj_files

        * Thuban/UI/projlist.py (ProjectionList): Merge the system_projs,
        user_projs parameters into one parameter proj_files which is a
        list of proj files.
        (ProjectionList._subscribe_proj_files)
        (ProjectionList._unsubscribe_proj_files): New. Move
        subscription/unsubscription of projfile messages to separate
        methods
        (ProjectionList.Destroy): The unsubscribe is now done in
        _unsubscribe_proj_files
        (ProjectionList.update_projections): We now have a list of proj
        file objects
        (ProjectionList.SetProjFiles): New method to set a new list of
        proj file objects

        * test/test_proj.py (ProjFileReadTests.test_get_system_proj_file):
        Specify explicitly which system proj file to load.

2003-11-11  Bernhard Herzog  <[email protected]>

        * Thuban/Model/load.py (SessionLoader.Destroy): New. Clear all
        instance variables to cut cyclic references. The GC would have
        collected the loader eventually but it can happen that it doesn't
        run at all until thuban is closed (2.3 but not 2.2 tries a bit
        harder and forces a collection when the interpreter terminates)
        (load_session): Call the handler's Destroy method to make sure
        that it gets garbage collected early. Otherwise it will be
        collected very late if at all and it holds some references to e.g.
        shapestores and the session which can lead to leaks (of e.g. the
        temporary files)

        * test/test_load.py (TestSingleLayer.test_leak): New. test for the
        resource leak in load_session

2003-11-10  Bernhard Herzog  <[email protected]>

        * Thuban/UI/baserenderer.py: Add a way to specify how layers in
        extensions are to be rendered.
        (_renderer_extensions): New. List with renderer for layers in
        extensions
        (add_renderer_extension): New. Add a renderer extension
        (init_renderer_extensions): New. Init the renderer extensions
        (BaseRenderer.render_map_incrementally): Search
        _renderer_extensions for how to draw unknown layer types
        (BaseRenderer.draw_raster_data): Add format parameter so that
        formats other than BMP can be drawn
        (BaseRenderer.draw_raster_layer): Pass an explicit format to
        draw_raster_data

        * Thuban/UI/renderer.py (raster_format_map): New. Mapping form the
        strings of the format parameter of draw_raster_data method to wx
        constants
        (MapRenderer.draw_raster_data): Add the format parameter and use
        raster_format_map to map it to the right wxwindows constant for
        wxImageFromStream

        * test/test_baserenderer.py (SimpleRenderer.draw_raster_data): Add
        the format parameter and record it
        (TestBaseRenderer.test_raster_no_projection): check the format
        paramter of the draw_raster_data method
        (TestBaseRenderer.test_renderer_extension): New. Test the renderer
        extension facility

2003-11-07  Bernhard Herzog  <[email protected]>

        Tweak the usage of the sqlite database to make common use cases
        more responsive. In most cases copying the data to the sqlite
        database takes so long that using sqlite doesn't have enough
        advantages.

        * Thuban/Model/transientdb.py (TransientTableBase.ValueRange): Add
        comments about performance and query the min and max in separate
        statements because only that way will indexes be used.
        (TransientTableBase.UniqueValues): Add some comments about
        performance.
        (AutoTransientTable.ValueRange, AutoTransientTable.UniqueValues):
        Do not copy the data to the transient DB but use the transient
        copy if it exists. See the new comments for the performance trade
        offs

        * test/test_transientdb.py
        (TestTransientTable.test_auto_transient_table): Make sure that the
        data is copied to the transient database at some point.

2003-11-03  Bernhard Herzog  <[email protected]>

        * Thuban/Model/data.py (ShapefileStore.ShapesInRegion): Bind some
        globals to locals so that it's a bit faster

2003-11-03  Bernhard Herzog  <[email protected]>

        * Thuban/UI/baserenderer.py
        (BaseRenderer.draw_shape_layer_incrementally): Use the ReadValue
        method. ReadValue is faster than ReadRowAsDict since it only reads
        one cell especially now that the dbf file objects actually
        implement it.

        * Thuban/Model/table.py (DBFTable.ReadValue): Use the new
        read_attribute method of the dbf objects

2003-11-03  Bernhard Herzog  <[email protected]>

        * Extensions/profiling/profiling.py (popup_dialog_box): New config
        variable to indicate whether the result should be shown in a
        dialog box
        (profile_screen_renderer, time_screen_renderer): Only show a
        dialog box if popup_dialog_box is true.
        (profile_screen_renderer): Flush stdout after the printing the
        first part of the "profiling..." message

        * Thuban/UI/baserenderer.py
        (BaseRenderer.draw_shape_layer_incrementally): Cache the pens and
        brushes for the groups so that they're not created over and over
        again

        * Thuban/Model/classification.py (Classification.__getattr__)
        (Classification._compile_classification)
        (Classification._clear_compiled_classification): New. Methods to
        manage a 'compiled' representation of the classification groups
        which is created on demand
        (Classification.InsertGroup, Classification.RemoveGroup)
        (Classification.ReplaceGroup): reset the compiled representation
        (Classification.FindGroup): Use the compiled representation to
        find the matching group
        (ClassGroupRange.GetRangeTuple): New. Return the range as a tuple

2003-10-31  Bernhard Herzog  <[email protected]>

        * Thuban/Model/classification.py (Classification.SetDefaultGroup):
        Send a CLASS_CHANGED message
        (Classification.RemoveGroup): Send a CLASS_CHANGED message and do
        not return the removed group since it wasn't used.

        * test/test_classification.py
        (TestClassification.test_set_default_group): New. Test the
        SetDefaultGroup method
        (TestClassification.test_insert_group): New. Test the InsertGroup
        method
        (TestClassification.test_remove_group): New. Test the RemoveGroup
        method
        (TestClassification.test_replace_group): New. Test the
        ReplaceGroup method

2003-10-31  Bernhard Herzog  <[email protected]>

        * test/test_classification.py (TestClassification.setUp):
        Subscribe to the CLASS_CHANGED messages
        (TestClassification.tearDown): New. Destroy the classification
        properly
        (TestClassification.test_defaults): Add tests for the default line
        width and whether no messages were sent yet
        (TestClassification.test_set_default_properties): Add tests for
        messages and setting the default line width
        (TestClassification.test_add_singleton)
        (TestClassification.test_add_range)
        (TestClassification.test_multiple_groups): Add tests for messages

2003-10-31  Bernhard Herzog  <[email protected]>

        Some more refactoring in preparation for new tests:

        * test/test_classification.py (TestClassification.setUp): New.
        Instantiate the classification here. Update the test methods
        accordingly.
        (TestClassification.test_multiple_groups): Make sure that the two
        singletons matching 1 are considered different.

2003-10-31  Bernhard Herzog  <[email protected]>

        * test/test_classification.py (red, green, blue): New. These
        constants were used in several cases. Update the relevant methods.
        (TestClassification.test_defaults)
        (TestClassification.test_set_default_properties)
        (TestClassification.test_add_singleton)
        (TestClassification.test_add_range)
        (TestClassification.test_multiple_groups)
        (TestClassification.test_deepcopy): New. These were formerly all
        part of the single method test.
        (TestClassification.test_deepcopy): Removed.
        (TestClassIterator): Removed. The test case is now a method of
        TestClassification since it tests part of the public interface of
        Classification
        (TestClassification.test_iterator): New. Used to be
        TestClassIterator effectively

2003-10-31  Jan-Oliver Wagner <[email protected]>

        GUIfied the functions of the profiling extension.

        * /Extensions/profiling/__init__.py: New: Init to make this
        directory a package.

        * Extensions/profiling/profiling.py: Moved menu entries to
        the Extensions menu. Applied _() for strings.
        (profile_screen_renderer): Catch the detailed printout and present
        it in a dialog.
        (time_screen_renderer): Raise a dialog to present the result instead
        of printing it to stdout.

2003-10-31  Bernhard Herzog  <[email protected]>

        * test/test_classification.py (TestClassGroupProperties)
        (TestClassGroup, TestClassGroupDefault, TestClassGroupRange)
        (TestClassGroupSingleton, TestClassIterator, TestClassification):
        Split TestClassification into several classes, one for each class
        being tested. TestClassification itself now only tests
        Classification. This split makes changes to the tests a bit easier

2003-10-31  Bernhard Herzog  <[email protected]>

        * Extensions/profiling/profiling.py: New. Extension to measure
        Thuban performance

2003-10-31  Frank Koormann <[email protected]>

        * Thuban/UI/legend.py (LegendPanel._OnRemoveLayer,
        LegendPanel._OnShowTable): New event handlers, call the corresponding 
        mainwindow methods.
        (LegendTree._OnRightClick): Added items to popup menu.

2003-10-30  Bernhard Herzog  <[email protected]>

        * Thuban/UI/dialogs.py (ThubanFrame.__init__): Handle
        EVT_WINDOW_DESTROY
        (ThubanFrame.OnDestroy): New. Handler for EVT_WINDOW_DESTROY. Does
        nothing but is convenient for the derived classes.

        * Thuban/UI/tableview.py
        (TableFrame.OnDestroy, LayerTableFrame.OnDestroy): New.
        Unsubscribe the messages here not in OnClose because that might
        get called multiple times. Fixes RT #2196
        (TableFrame.OnClose, LayerTableFrame.OnClose): Removed. Not needed
        anymore.

        * README: Update the minimum requirement for wxPython. Since we
        now use the EVT_WINDOW_DESTROY event, we need at least 2.4.0.4,
        the version in which that was introduced for all platforms

2003-10-30  Frank Koormann <[email protected]>

        * Thuban/UI/join.py (JoinDialog.OnJoin): Wrapped the major parts of 
        the join process in a ThubanBeginBusyCursor, ThubanEndBusyCursor
        frame.

2003-10-30  Jan-Oliver Wagner <[email protected]>

        Improved APR import extension, added further EPSG definitions
        and some cleanup regarding string class.

        * test/test_proj.py (TestProjection.test_get_projection_units_geo):
        Added test for alias 'longlat'.

        * Resources/Projections/epsg-deprecated.proj: New. Contains
        deprecated EPSG definitions.

        Copied from importAPR and provided with documentation.

        * Extensions/importAPR/importAPR.py (APR_BLnSym, APR_BMkSym, APR_BShSym):
        Moved to apr.py.
        (APR_View): Added object ref 'ITheme'.

        * Thuban/Lib/fileutil.py, Thuban/UI/proj4dialog.py: Replaced string
        split function by corresponding use of the string class method.

        * Thuban/Model/xmlwriter.py: Replaced string replace function by
        corresponding string method.

2003-10-29  Bernhard Herzog  <[email protected]>

        * Thuban/UI/baserenderer.py
        (BaseRenderer.draw_shape_layer_incrementally): Speed up the
        special case of a classification that only has the default group

2003-10-27  Bernhard Herzog  <[email protected]>

        * po/fr.po, po/es.po: Updated translations from Daniel Calvelo

        * po/de.po: Update.

        * Thuban/UI/application.py
        (ThubanApplication.ShowExceptionDialog): Handle translation of the
        dialog message properly

2003-10-27  Bernhard Herzog  <[email protected]>

        Rework how localization works so that we use wx's translation
        functions when running Thuban as a normal application but not when
        we don't need any UI, such as in the test suite. See the comment
        in Thuban/__init__.py for details

        * Thuban/__init__.py (_): Add one level of indirection to make the
        translation handling more flexible and to make it possible to use
        either wx's translation services or not.
        (gettext_identity, translation_function_installed)
        (install_translation_function): New function to help with this

        * Thuban/UI/__init__.py: Install the wx specific translation
        function if it's OK to do that

        * test/support.py (initthuban): Install a dummy translation
        function so that importing Thuban.UI doesn't install a wx specific
        one for which would need to import wxPython

2003-10-27  Bernhard Herzog  <[email protected]>

        * HOWTO-Release: Source archives should be created first and the
        binary packages should be created from the source archives.
        There's an official debian package now so there's no need to test
        the rpm on debian anymore

2003-10-27  Bernhard Herzog  <[email protected]>

        Several rendering changes:

         - Render the selection into a separate bitmap so that only that
           bitmap needs to be redrawn when the selection changes

         - Render incrementally showing previews and allowing interaction
           before rendering is complete

         - Update the renderer interface a bit. Most parameters of

        and the update region as parameters. Update the doc-string
        (BaseRenderer.render_map_incrementally): New. Generator function
        to renders the map incrementally
        (BaseRenderer.render_map): Remove the map argument (it's now in
        the constructor) and simply iterate over the
        render_map_incrementally generator to draw the map.
        (BaseRenderer.draw_shape_layer_incrementally)
        (BaseRenderer.draw_shape_layer): Renamed to
        draw_shape_layer_incrementally and changed into a generator that
        yields True every 500 shapes. Used by render_map_incrementally to
        render shape layers incrementally

        * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Removed the
        map and region parameters which are now in the constructor
        (ScreenRenderer.RenderMapIncrementally): New. Public frontend for
        the inherited render_map_incrementally.
        (BaseRenderer.draw_shape_layer): Removed.
        (ScreenRenderer.draw_selection_incrementally): New. The selection
        drawing part of the removed draw_shape_layer as a generator
        (ScreenRenderer.layer_shapes): Update because of the region
        parameter change

        exists
        (MapCanvas.OnIdle): Update the logic to deal with incremental
        rendering and the selection bitmap
        (MapCanvas._do_redraw): Handle the instantiation of the render
        iterator and the redraws during rendering
        (MapCanvas._render_iterator): New. Generator to incrementally
        redraw both bitmaps
        (MapCanvas.Export): Adapt to new renderer interface.
        (MapCanvas.full_redraw): Reset the selection bitmap and the
        renderer iterator too
        (MapCanvas.redraw_selection): New. Force a redraw of the selection
        bitmap
        (MapCanvas.shape_selected): Only redraw the selection bitmap

        * test/test_baserenderer.py
        (TestBaseRenderer.test_polygon_no_projection)
        (TestBaseRenderer.test_raster_no_projection)
        (TestBaseRenderer.test_point_map_projection)

        (TestBaseRenderer.test_point_with_classification): Adapt to new
        renderer interface

2003-10-24  Bernhard Herzog  <[email protected]>

        * libraries/thuban/wxproj.cpp (draw_polygon_shape)
        (point_in_polygon_shape, shape_centroid): Raise an exception if
        the shape can't be read. Previously invalid shape ids would lead
        to a segfault.

        * test/test_wxproj.py (TestShapeCentroid.test_invalid_shape_id):
        New. test whether an exception is raised for invalid shape ids

2003-10-24  Jan-Oliver Wagner <[email protected]>

        * Thuban/Model/proj.py (Projection.GetProjectedUnits): Added 'longlat'
        as alias for 'latlong'.

        * Thuban/UI/projdialog.py (ProjFrame.__init__): Added 'longlat'
        as alias for 'latlong'.

2003-10-24  Jan-Oliver Wagner <[email protected]>

        * Thuban/UI/projdialog.py (ProjFrame.proj_selection_changed): Set
        the projection even for the UnknownPanel.
        (UnknownProjPanel.__init__): Define the text and create the textctrl
        widget.
        (UnknownProjPanel._DoLayout): Replaced static text widget by the
        textctrl created in __init__.
        (UnknownProjPanel.SetProjection): Set the text for the text ctrl
        including the parameters of the projection.
        
2003-10-24  Jan-Oliver Wagner <[email protected]>

        * Resources/Projections/epsg.proj: New. This is a list of
        EPSG codes with parameters for proj. The list has been
        generated using devtools/create_epsg.py based on the
        file nad/epsg of the proj 4.4.7 package. Four projection
        definitions have been deleted as they are not accepted by proj:
        "CH1903+ / LV95", "Bern 1898 (Bern) / LV03C", "CH1903 / LV03"
        and "HD72 / EOV".

2003-10-22  Bernhard Herzog  <[email protected]>

        Some more tweaks to the projection dialog which should fix RT
        #1886.

        * Thuban/UI/projlist.py (ProjectionList.Destroy): Unsubscribe from
        the ProjFile's messages and call the base class methods correctly
        (ProjectionList.SelectProjection): Set the wxLIST_STATE_FOCUSED
        flag on the newly selected item too. Otherwise some other item is
        focused and the first time the focus is moved with the keyboard
        the selection moves in unexpected ways.

        * Thuban/UI/projdialog.py (ProjFrame.__init__): Do not set the
        focus on the OK button, only on the projection list. That way the
        list really has the focus initially
        (ProjFrame.OnClose): Call the projection list's Destroy method to
        make it unsubscribe all messages

2003-10-21  Bernhard Herzog  <[email protected]>

        Rework the projection dialog to fix a few bugs, including RT 2166
        and most of 2168

        * Thuban/UI/projlist.py: New. The class ProjectionList is a
        special wxListCtrl to show a list of projections in a more MVC
        fashion

        * Thuban/UI/projdialog.py (ProjFrame): Substantial changes
        throughout the class. The main change is to use the ProjectionList
        class instead of a normal wxListBox. Also, add an explicit
        "Unknown" projection to the projection choice control.
        (ProjPanel.__init__): Add an "unknown" ellipsoid
        (TMPanel.__init__, LCCPanel.__init__): Tweak the order of
        instantiation of the panel's controls to make the tab-order more
        natural

2003-10-21  Bernhard Herzog  <[email protected]>

        * test/test_load.py (TestSingleLayer.file_contents)
        (TestSingleLayer.test): Add non-ascii characters to the titles of
        session, map and layer. This is effectively a port of the

        Popup menu for legend. Scheduled for the 1.2 release this was too
        simple to implement: The popup menu is bound to the legend tree, while
        the events are hanlded by its anchestor, the legend panel. This

        * Thuban/Model/proj.py (ProjFile.Add): Do not check whether the
        projection is already in the list. This is *a lot* faster when
        loading files with hundreds of projections since it saves a linear
        search. OTOH this will allow adding the same projection to the
        user.proj file multiple times in the projection dialog but we'll
        deal with that later

        get_system_proj_file and return the ProjFile object and not a list
        of ProjFile objects. Update the callers.
        (get_user_proj_files, get_user_proj_file): Rename to
        get_user_proj_file return the ProjFile object and not a list of

        the test cases
        (ViewPortTest.setUp): Use MockView instead of ViewPort

        * Thuban/UI/viewport.py (ViewPort.GetTextExtent): Turn this method
        into what would be a "pure virtual function" in C++: always raise
        NotImplementedError. Mock implementations for test cases don't
        belong into the real code

2003-10-02  Bernhard Herzog  <[email protected]>

        * test/test_layer.py (TestLayer.test_empty_layer): Explicitly

2003-10-01  Jan-Oliver Wagner <[email protected]>

        * Thuban/UI/tree.py, Thuban/UI/main.py: Remove the #! line as
        it annoys lintian which warns about these files not being
        executable. The #! isn't necessary here since if you absolutely
        must execute them you can always say "python <filename>".

2003-09-26  Bernhard Herzog  <[email protected]>

        * Thuban/Model/classgen.py (GenQuantiles0): Removed since it's
        only used in GREAT-ER but not used in Thuban itself. When GREAT-ER
        is ported to a newer the import will fail, so it should be noticed
        immediately that this function is gone.
        Fixes RT#1919

2003-09-26  Bernhard Herzog  <[email protected]>

        test support modules which do not use anything from thuban itself
        (ThubanTestProgram.runTests): Remove unnecessary debug print

2003-08-28  Bernhard Herzog  <[email protected]>

        more postgis specific but much faster method to get the bounding
        box

2003-08-26  Bernhard Herzog  <[email protected]>

        * Thuban/Model/postgisdb.py (PostGISTable.Title)
        (PostGISShapeStore.AllShapes): Add these missing methods.
        (PostGISShapeStore.ShapesInRegion): No need to raise

2003-08-25  Bernhard Herzog  <[email protected]>

        * Thuban/Model/postgisdb.py (shapetype_map): Add MUTLIPOLYGON.

        * test/test_postgis_db.py (PolygonTests): New class containing

        * Thuban/UI/application.py
        (ThubanApplication.run_db_param_dialog): New. Suitable as a
        db_connection_callback. Main difference is that the dialog run
        from this method doesn't have a parent so it can be used even when
        there is no main window
        (ThubanApplication.OpenSession): Use self.run_db_param_dialog if
        no db_connection_callback was given. This way the dialog pops up

        * Thuban/UI/view.py (MapCanvas.OnLeftUp): Release the the mouse
        before calling MouseLeftUp. MouseLeftUp may pop up modal dialogs
        which leads to an effectively frozen X session because the user
        can only interact with the dialog but the mouse is still grabbed
        by the canvas.
        Also, call the tool's Hide method before MouseLeftUp because
        MouseLeftUp may change the tool's coordinates.

2003-08-25  Bernhard Herzog  <[email protected]>

        * Thuban/UI/application.py (ThubanApplication.OpenSession): Catch
        LoadCancelled exceptions and handle them by returning immediately.

2003-08-25  Bernhard Herzog  <[email protected]>

        GUI part of loading sessions with postgis connections which may
        require user interaction to get passwords or updated parameters

        * Thuban/UI/dbdialog.py (DBDialog): Reimplement to make it look a
        bit nucer and be more generic.
        (DBFrame.OnAdd): Adapt to new DBDialog interface

        * Thuban/UI/application.py (ThubanApplication.OpenSession): New
        optional parameter db_connection_callback which is passed to
        load_session.

        * Thuban/UI/mainwindow.py (MainWindow.run_db_param_dialog): New.
        Suitable as a db_connection_callback
        (MainWindow.OpenSession): Use self.run_db_param_dialog as the
        db_connection_callback of the application's OpenSession method


2003-08-25  Bernhard Herzog  <[email protected]>

        dispatchers dictionary
        (SessionLoader.check_attrs): Two new conversions, ascii to convert
        to a byte-string object and idref as a generic id reference

        * Thuban/Model/data.py (DerivedShapeStore.RawShapeFormat): New.
        Simply delegates to the original shapestore.

        * test/test_derivedshapestore.py
        (TestDerivedShapeStore.test_raw_format): New. Test case for
        DerivedShapeStore.RawShapeFormat

2003-08-07  Bernhard Herzog  <[email protected]>

        Add raw data interface to shape objects.

        * Thuban/Model/data.py (ShapefileShape, Shape): Rname the shape
        class to ShapefileShape which now holds shapefile specific
        information.
        (ShapefileShape.compute_bbox): Simplified to not cache any
        information. The way this method is used that shouldn't matter
        performance wise.
        (ShapefileShape.RawData): New. Return the shapeid which is the raw
        data format for shapes from shapefiles.
        (ShapefileStore.RawShapeFormat): New. Return the raw datatype used
        in the shape objects returned by a shapestore. For a
        ShapefileStore this is always RAW_SHAPEFILE.
        (RAW_PYTHON, RAW_SHAPEFILE): Constants for the RawShapeFormat
        method.

        * test/test_shapefilestore.py
        (TestShapefileStore.test_raw_format): New test to test the raw
        format feature of shapes.

        * Thuban/Model/layer.py: Remove the unused import of Shape from
        data. It was only there for interface compatibility but it's not
        used inside of Thuban and the generic Shape class has gone away.

        * Thuban/UI/renderer.py (MapRenderer.low_level_renderer): Check
        the raw data format and only use an optimized version of its a
        shapefile.

2003-08-07  Bernhard Herzog  <[email protected]>

        * test/test_baserenderer.py (SimpleShape): Shape class for the
        tests.
        (SimpleShapeStore.Shape): Use SimpleShape instead of
        Thuban.Model.data.Shape to make the tests independed of the coming
        changes.

2003-08-07  Bernhard Herzog  <[email protected]>

        * test/support.py (SkipTest, ThubanTestResult, ThubanTestRunner)
        (ThubanTestProgram): New classes that extend the respective
        classes from unittest. These new version support skipping tests
        under certain expected conditions. In the Thuban test suite we
        uses this for tests that require the optional gdal support.
        (run_tests): Use ThubanTestProgram instead of the unittest.main()

        * test/runtests.py (main): Use the new ThubanTestRunner instead of
        the normal one from unittest

        * test/test_layer.py (TestLayer.test_raster_layer): If this test
        is not run because gdal support isn't available report this to the
        runner.

        * test/test_baserenderer.py
        (TestBaseRenderer.test_raster_no_projection): Do not run this test
        if gdal support isn't available and report this to the runner.

2003-08-06  Bernhard Herzog  <[email protected]>

        Rearrange the renderers a bit, partly in preparation for changes
        required for the postgis merge, partly to make it more testable.
        Also make the representation of coordinates in Shapes more
        consistent.

        * Thuban/UI/renderer.py (MapRenderer): Most of the code/methods in
        this class is now in BaseRenderer. This class is now practically
        only a specialization of BaseRenderer for rendering to an actual
        wx DC.
        (ScreenRenderer.draw_shape_layer): Use self.low_level_renderer()
        to get the shapetype specific rendering functions.

        * Thuban/UI/baserenderer.py: New file with the basic rendering
        logic. The code in this file is completely independend of wx.
        (BaseRenderer): Class with the basic rendering logic

        * test/test_baserenderer.py: New. Test cases for BaseRenderer

        * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
        error_on_redraw to guard agains endless loops and stack overflows
        when there's a bug in the rendering code that raises exceptions.
        (MapCanvas.OnIdle, MapCanvas._do_redraw): Split the actual
        rendering into a separate method _do_redraw so that error handling
        is a bit easier. When an exception occurs, set error_on_redraw to
        true. When it's true on entry to OnIdle do nothing and return
        immediately.

        * Thuban/Model/data.py (ShapefileStore.Shape): For consistency, a
        Shape object will always have the coordinates as a list of list of
        coordinate pairs (tuples).
        (Shape.compute_bbox): Adapt to new representation.

        * Thuban/UI/viewport.py (ViewPort.find_shape_at)
        (ViewPort.LabelShapeAt): Adapt to new coordinate representation in
        Shape objects.

        * test/test_shapefilestore.py
        (ShapefileStoreTests.assertFloatTuplesEqual)
        (ShapefileStoreTests.assertPointListEquals): Rename to
        assertPointListEquals and change purpose to checking equality of
        the lists returned by Shape.Points().
        (TestShapefileStoreArc.test_shape)
        (TestShapefileStorePolygon.test_shape)
        (TestShapefileStorePoint.test_shape): Use the new
        assertPointListEquals instead of assertFloatTuplesEqual

        * test/test_layer.py (TestLayer.assertFloatTuplesEqual)
        (TestLayer.assertPointListEquals): Rename to assertPointListEquals
        and change purpose to checking equality of the lists returned by
        Shape.Points().
        (TestLayer.test_arc_layer, TestLayer.test_arc_layer)
        (TestLayer.test_polygon_layer, TestLayer.test_point_layer)
        (TestLayer.test_derived_store): Use the new assertPointListEquals
        instead of assertFloatTuplesEqual

        * test/test_derivedshapestore.py
        (TestDerivedShapeStore.assertFloatTuplesEqual)
        (TestDerivedShapeStore.assertPointListEquals): Rename to
        assertPointListEquals and change purpose to checking equality of
        the lists returned by Shape.Points().
        (TestDerivedShapeStore.test_shape): Use the new
        assertPointListEquals instead of assertFloatTuplesEqual

2003-08-06  Jan-Oliver Wagner <[email protected]>

        * Thuban/UI/projdialog.py (UTMPanel._OnPropose): Added test for
        a bounding box. A dialog is raised in case, no bounding box
        is found. This fixes bug #2043:
        https://intevation.de/rt/webrt?serial_num=2043

2003-08-05  Bernhard Herzog  <[email protected]>

        * Thuban/Model/color.py (Color.__repr__): Make the repr of a color
        object look like a Color instantiation. Formerly it looked like a
        tuple.

        * test/test_color.py (TestColor.test_repr)
        (TestColor.test_equality, TestColor.test_inequality): New. test
        some more apects of the Color class
        (TestTransparent.test_repr, TestTransparent.test_hex)
        (TestTransparent.test_equality): New. Test cases for the
        Transparent object.

2003-08-04  Jan-Oliver Wagner <[email protected]>

        * Doc/manual/thuban-manual.xml: a number of small improvements.
        The resulting file is the version submitted for GREAT-ER II.

        Thuban/Model/resource.py: Insert cvs keywords and doc-strings.

        * Thuban/UI/common.py: Insert cvs keywords and doc-strings.
        (Color2wxColour, wxColour2Color, ThubanBeginBusyCursor)
        (ThubanEndBusyCursor): Add doc-strings

2003-08-01  Bernhard Herzog  <[email protected]>

        First step towards PostGIS integration. More abstraction by movin
        more code from the layer to the shapestore. More methods of the
        layer are now simply delegated to the equivalent method of the
        shapestore. The SHAPETYPE_* constants are now in data not in
        layer.

        * Thuban/Model/data.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
        (SHAPETYPE_POINT, Shape): Move these constants and classes from
        layer.py to data.py
        (ShapefileStore.__init__): More Initialization for the new methods
        and functionality.
        (ShapefileStore.ShapeType, ShapefileStore.NumShapes)
        (ShapefileStore.BoundingBox, ShapefileStore.ShapesInRegion)
        (ShapefileStore.Shape): New methods that were formerly implemented
        in the layer.
        (DerivedShapeStore.Shape, DerivedShapeStore.ShapesInRegion)
        (DerivedShapeStore.ShapeType, DerivedShapeStore.NumShapes)
        (DerivedShapeStore.BoundingBox): New. DerivedShapeStore
        equivalents of the new shape methods. These versions are simply
        delegated to the original shapstore.

        * Thuban/Model/layer.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
        (SHAPETYPE_POINT, Shape): Removed. They're now in data.py
        (Layer.SetShapeStore): Removed the initializatin of instance
        variables that were needed for the stuff that's now in
        ShapefileStore
        (Layer.BoundingBox, Layer.NumShapes, Layer.ShapeType)
        (Layer.Shape, Layer.ShapesInRegion): Simply delegate to the
        shapestore.

        * Thuban/UI/classifier.py, Thuban/UI/renderer.py,
        Thuban/UI/viewport.py: Import the SHAPETYPE_* constants from data
        instead of layer.

        * test/test_shapefilestore.py: New. Tests for ShapefileStore.

        * test/test_derivedshapestore.py: New. Tests for DerivedShapeStore.

        * test/test_layer.py: Import the SHAPETYPE_* constants from data
        instead of layer.
        (TestLayer.test_derived_store): Remove the test for the exception
        when instantiating the DerivedShapeStore with an incompatible
        table which is now in test_derivedshapestore.py. Add some more
        tests of the layer methods to determine whether they work for a
        DerivedShapeStore as well.

2003-07-31  Jonathan Coles   <[email protected]>

        * Doc/manual/thuban-manual.xml: Fix the list of required packages
        by just listing the name and where they can be found.

2003-07-31  Frank Koormann   <[email protected]>

        * Doc/manual/thuban-manual.xml: 
        Changed the screenshot elements to figure.
        Changed some variablelist elements to itemizedlist.
        Added section on GDAL formats.

2003-07-31  Jonathan Coles   <[email protected]>

        * Doc/manual/thuban-manual.xml: Added a few sentences about
        the Fix Border Color option when generating classes.

2003-07-30  Jonathan Coles   <[email protected]>

        * Thuban/Model/classgen.py: Add docstrings. Rename specific
        Ramp instances to use lower_case_style.

        * Thuban/UI/classgen.py: Use renamed Ramp instances.
        
        * Thuban/UI/classifier.py: Add docstrings.

        * Thuban/UI/dock.py: Add docstrings.

        * test/test_classgen.py: Use renamed Ramp instances.

2003-07-30  Bernhard Herzog  <[email protected]>

        * Thuban/Lib/connector.py (QueueingPublisher): Removed. This class
        was never used in Thuban.

2003-07-30  Bernhard Herzog  <[email protected]>

        * Thuban/UI/join.py (JoinDialog.__init__): Use the table's Title()
        method directly instead of going through the transient_table
        method. This faster because transient_table may force the copy of
        a DBF file into the transient database and setting a table's title
        doesnm't affect the title of the associated transient table, so
        this fixes RT #2042

        * Thuban/UI/main.py (__version__): Don't import the already
        removed show_exception_dialog.

2003-07-29  Jonathan Coles   <[email protected]>

        * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
        Put back this method and remove the equivalent function since we
        are setting the exception hook from within this class (OnInit).

        * Doc/manual/thuban-manual.xml: Fixed typos and wording, clarified
        some points, and added more screen shots.

2003-07-29  Bernhard Herzog  <[email protected]>

        * Thuban/Model/data.py: Remove the now unused import of warnings

2003-07-29  Bernhard Herzog  <[email protected]>

        * Thuban/Model/data.py (SimpleStore): Removed. This class has been
        deprecated since before the 0.8 release and isn't used in Thuban
        itself anymore.

        * Thuban/Model/transientdb.py: Remove some unnecessary imports

2003-07-29  Jonathan Coles   <[email protected]>

        * Thuban/UI/application.py (ThubanApplication.OnInit): set the 
        python exception hook here so that we are sure to catch any
        Thuban exception that happen during initialization.

        * Thuban/UI/main.py (main): Don't set the exception hook here,
        it will get set in ThubanApplication.OnInit.

2003-07-29  Jonathan Coles   <[email protected]>
                                                                            
        * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
        Removed and called it show_exception_dialog() so that the exception
        handler can be set before the class is created.
                                                                            
        * Thuban/UI/main.py (main): Install the exception handler before
        a ThubanApplication is created.

        cursor from dialog box.

2003-07-28  Jonathan Coles   <[email protected]>

        * Doc/manual/thuban-manual.xml: More screenshots and more chapters.

        * Thuban/Model/range.py, Thuban/version.py: Remove the #! line as
        it annoys lintian which warns about these files not being
        executable. The #! isn't necessary here since if you absolutely
        must execute them you can always say "python <filename>".

        * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Remove
        superfluous code to set brush and pen for point shapes

        * Thuban/UI/viewport.py: Remove commented out code that wouldn't

        with Begin/EndDrawing() calls to ensure we aren't doing to
        many updates to the dc during rendering.
        (ScreenRenderer.draw_shape_layer): self.draw_point_shape takes
        a pen and brush argument so they need to be passed to the function.

        * Thuban/UI/viewport.py (ViewPort.calc_min_max_scales): New.
        Calculates the minimum and maximum scale values. Factored out
        of set_view_transform so that it could be used to zoom all the
        way into a single point.
        (ViewPort.set_view_transform): Call calc_min_max_scales().
        (ViewPort.FitSelectedToWindow): Zoom to the maximum scale
        if only a single point is selected.

2003-07-18  Bernhard Herzog  <[email protected]>

        * test/runtests.py: The test suite can now be run without an X
        connection. To make sure this remains true, remove the DISPLAY
        environment variable so that an error occurs if the wxGTK is
        imported accidentally

2003-07-18  Bernhard Herzog  <[email protected]>

        * Thuban/UI/viewport.py: Remove unused imports

        * Thuban/UI/view.py: Remove unused imports

2003-07-18  Bernhard Herzog  <[email protected]>

        * test/test_export.py Remove unused imports. The OutputTransform
        function is now in viewport.py and is called output_transform
        (TestScalebar.test_output_transform)
        (TestScalebar.test_OutputTransform): Renamed to
        test_output_transform and updated to use output_transform instead
        of OutputTransform

        * Thuban/UI/view.py (OutputTransform): Moved to viewport.py and
        renamed.
        (MapCanvas.Export, MapPrintout.draw_on_dc): OutputTransform was

        Rename to GetClassificationColumn.
        (Layer.SetClassificationColumn, Layer.SetClassificationField):

        (Layer._classification_changed, Layer.ClassChanged): Rename to
        _classification_changed. Update the callers.
        (Layer.SetShapeStore): Further field->column renames.

        * Thuban/Model/load.py (SessionLoader.start_classification) 
        (SessionLoader.start_clpoint): Updates because of

        (Classifier._OnTry, Classifier._OnRevert): Updates because of
        field->column method name changes in the Layer class

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Updates
        because of field->column method name changes in the Layer class

        * Thuban/UI/viewport.py (ViewPort.find_shape_at): Updates because

        method name changes in the Layer class
        (TestLayerModification.setUp): Subscribe to LAYER_CHANGED as well
        (TestLayerModification.test_sanity)
        (TestLayerModification.test_initial_settings): remove unsued code
        and rename to test_sanity.
        (TestLayerModification.test_set_classification): New test for
        SetClassification and SetClassificationField.

2003-07-18  Bernhard Herzog  <[email protected]>

        * test/test_classgen.py (TestFixedRamp.test): Extend test to check
        the non-fixed values as well. The old test would have accepted a
        fixed ramp that only returnes the fixed properties

2003-07-17  Jonathan Coles   <[email protected]>

        * Doc/manual/mainwindow.png, Doc/manual/mainwindow.xcf: Screen
        shots for the manual. The XCF file is the source image and
        has additional layers to support changes.

        * Doc/manual/thuban-manual.xml: Wrote an initial Introduction.

        * Thuban/UI/classifier.py (Classifier.__BuildClassification):
        Return both the new class and the field name.

        * Thuban/UI/mainwindow.py (MainWindow.ToggleLegend): Don't 
        fit the map to the window as this changes any zoom level that
        the user may have set.

2003-07-16  Jonathan Coles   <[email protected]>

        * Thuban/Model/classgen.py (generate_singletons,
        generate_uniform_distribution, generate_quantiles): Remove
        fixes parameter, but maintain the same functionality by having
        the calling function pass a FixedRamp object for the ramp.
        (FixedRamp): New. Adapts a ramp to have fixed property values.

        * Thuban/Model/classification.py: Use new CLASS_CHANGED message.
        (Classification): Inherit from Publisher.
        (Classification.__init__): Remove the layer parameter. 
        Classifications no longer need to have a parent layer.
        (Classification.GetField, Classification.GetFieldType, 
        Classification.SetFieldInfo): Removed. The field name is stored
        in the layer, and the type can be retreived by calling
        Layer.GetFieldType().
        (Classification._set_layer, Classification.GetLayer): Removed.
        Classifications no longer have a parent layer.

        * Thuban/Model/layer.py (Layer.Destroy): Unsubscribe from the
        classification. 
        (Layer.SetShapeStore): Reset the classification first while

        (Layer.GetClassificationField, Layer.SetClassificationField):
        New. Method for getting/setting the field to classify on.
        (Layer.SetClassification): Simplified now that the layer 
        simply has to hold a reference to the classification and not
        tell the classification who owns it.
        Fixes RTbug #2023.

        * Thuban/Model/load.py (SessionLoader.start_classification):
        Set the field name on the layer, not the classification.

        classification is modified.

        * Thuban/Model/save.py (SessionSaver.write_classification):
        Get the field name and type from the layer.

        * Thuban/Model/table.py (table_to_dbf, table_to_csv): Renamed
        parameter records to rows and add docstring. Fixes RTbug #1997.

        * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Use a fixed
        ramp when we need to fix certain values of a ramp rather than
        using the old fixes parameter. Fixes RTbug #2024.

        * Thuban/UI/classifier.py (ClassGrid.CreateTable): Add fieldType
        parameter.
        (ClassTable.Reset): Add fieldType parameter and use it, rather
        than asking the classification.
        (Classifier.__init__): Remember the original class's field
        and ask the layer for the field type, rather than the classification.
        (Classifier.__SetGridTable): Retrieve the field and field type
        for the table because they are not in the classification.
        (Classifier._OnTry, Classifier._OnRevert): Set the classification
        field on the layer in addition to the classification itself.

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Get the
        classification field from layer.

        * Thuban/UI/viewport.py (ViewPort.find_shape_at): Get the
        classification field from layer. Split up tests and remove
        *-imports. Fixes RTbug #1992.

        * test/test_classgen.py (TestFixedRamp): Test for the FixedRamp class.

        * test/test_classification.py
        (TestClassification.test_classification): Remove tests for methods
        that no longer exist.

        * test/test_layer.py (SetShapeStoreTests.setUp): Classification
        __init__ no longer has a field parameter, use SetClassificationField.
        (SetShapeStoreTests.test_sanity): Use layer object to get class
        field info.

        * test/test_save.py (SaveSessionTest.testClassifiedLayer): Use
        SetClassificationField on layer to set class field info.

        * test/test_viewport.py: Renamed from test/test_view.py.

2003-07-16  Jan-Oliver Wagner <[email protected]>

        * Doc/manual/thuban-manual.xml: Added authors and an initial
        coarse structure.

2003-07-15  Bernhard Herzog  <[email protected]>

        * test/support.py (FloatComparisonMixin): This is a mix-in class
        and therefore should not be derived from any other class.

        * test/test_range.py (RangeTest): FloatComparisonMixin is a
        mix-in, so derive from TestCase as well.

2003-07-15  Bernhard Herzog  <[email protected]>

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Rework the
        draw_func handling a bit to remove one layer of indirection. This
        makes the renderer about 10% faster in the non-classifying case
        and the code a bit cleaner
        (MapRenderer.draw_point_shape): Add the pen and brush parameters
        and set them in the dc. Now the draw_point_shape method and
        wxproj's draw_polygon_shape function have basically the same
        signature so that both can be directly used as draw_func

2003-07-15  Bernhard Herzog  <[email protected]>

        * Thuban/Model/save.py (SessionSaver.write_classification): Encode
        string values (in addition to the labels) as UTF 8

        title to latin1.  Fixes https://intevation.de/rt/webrt?serial_num=2013

        * test/test_load_0_8.py (TestUnicodeStrings): New, test load of 
        unicode strings from session file: session title, map title and 
        projection name.
        
2003-07-10  Jonathan Coles   <[email protected]>

        * Thuban/UI/viewport.py (Tool.MouseUp): Should have called
        drag_stop, not drag_move when the mouse is released.

2003-07-10  Jonathan Coles   <[email protected]>

        The most important part of this is the seperation of view.py into
        two pieces. viewport.py now has a class called ViewPort which
        contains all the non-wx parts of view.py and can therefore be
        tested. view.py contains only the wx-specific parts and is fairly
        simple.

        * Thuban/UI/view.py: Stripped out all non-wx functionality. Fixes
        RTTbug #1992.
        * Thuban/UI/viewport.py: New. Contains non-wx view functionality.

        be held constant over the generated classification groups.
        (CustomRamp.GetProperties): Remove unused variables.

        * Thuban/Model/map.py (Map.SetProjection): Send the old
        projection as an argument to listeners of the MAP_PROJECTION_CHANGED
        event.

        * Thuban/Model/table.py (table_to_dbf, table_to_csv): Added 'records' 
        parameter which is a list of records that restricts which
        records are saved. Fixes RTbug #1997.

        * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
        Port exception dialog from GREAT-ER. Fixes RTbug #1993.

        * Thuban/UI/classgen.py (ClassGenDialog.__init__): Add controls
        to allow the user to fix line color/width on generated groups.
        (ClassGenDialog.OnOK): Use new 'fixes' parameter of the generate_*
        functions to optionally fix group properties.

        * Thuban/UI/main.py (main): Set exception hook to the 
        ShowExceptionDialog. Fixes RTbug #1993.

        the table window when it is selectd to be shown.

        * Thuban/UI/tableview.py (QueryTableFrame.__init__): Add an
        Export Selection button and move the export buttons underneath
        the table.
        (QueryTableFrame.UpdateStatusText): Added event argument so
        that it can respond to grid selection events. The status text
        is now updated even when the table is not associated with a
        layer as was previously assumed.
        (QueryTableFrame.OnGridSelectRange, OnGridSelectCell): Removed.
        UpdateStatusText responds to these events.
        (QueryTableFrame.OnSaveAs): Renamed to doExport.
        (QueryTableFrame.doExport): Helper function that saves the
        entire table, or selected rows, to a file.
        (QueryTableFrame.OnExport, QueryTableFrame.OnExportSel): New.
        Respond to export button events and call doExport.

        * extensions/thuban/gdalwarp.cpp (ProjectRasterFile): Make sure
        the function doesn't return NULL without first setting a Python
        Error.

        * test/runtests.py (main): Only print "Unknown option" for
        unsupported options.

        MAP_PROJECTION_CHANGED events send the old projection.

        * test/test_session.py 
        (TestSessionWithContent.test_forward_map_projection): 
        MAP_PROJECTION_CHANGED events send the old projection.

        * test/test_table.py (TableTest): Update tests to use non-deprecated
        functions.

2003-07-08  Bernhard Herzog  <[email protected]>

        * Thuban/Model/transientdb.py (TransientTableBase.Width): The type
        constants in the column objects are the standard ones defined in
        the table module.

        * test/test_transientdb.py
        (TestTransientTable.test_transienttable_to_dbf): New. Test whether
        exporting transient tables as DBF works. This should catch the bug
        just fixed in TransientTableBase.Width.

2003-07-08  Bernhard Herzog  <[email protected]>

        * Thuban/Model/classgen.py (CustomRamp.GetProperties): Compute the
        interpolated colors correctly.

        New. Test case for the fix in classgen.py

2003-07-08  Bernhard Herzog  <[email protected]>

        * test/runtests.py (main): Make the default output less verbose
        and add a verbosity option (-v) to get the old output

2003-07-08  Bernhard Herzog  <[email protected]>

        * test/test_load_0_8.py: New. Effectively a copy of test_load.py
        as of Thuban 0.8. These are now tests to determine whether Thuban
        can still read files generated by Thuban 0.8

        * test/test_load.py (LoadSessionTest.dtd)
        (TestSingleLayer.file_contents)

        * Thuban/Model/classgen.py (generate_singletons, 
        generate_uniform_distribution, generate_quantiles,
        GenQuantiles0): The denominator was one to high when

        to never to reach one.

2003-07-02  Jonathan Coles   <[email protected]>

        Changed the singature of ClassGroupRange.__init__ and
        ClassGroupRange.SetRange() so that the min/max values are
        passed as a tuple. This makes a better calling scheme for
        when a Range object is passed instead.

        * Thuban/Model/classgen.py: Fixed parameters to 
        ClassGroupRange constructor.

        * Thuban/Model/classification.py (ClassGroupRange.__init__):
        Consolidate the min/max parameters into a single _range which
        can either be a tuple or a Range object.
        (ClassGroupRange.SetRange): Consolidate the min/max parameters 
        into a single _range which can either be a tuple or a Range object.

        * Thuban/Model/load.py (SessionLoader.start_clrange): Fix
        call to ClassGroupRange constructor to use a tuple.

        * Thuban/Model/layer.py (Layer.SetClassification): Switch
        the classification instance variable to the new class 
        before calling _set_layer otherwise subscribers to a 
        LAYER_CHANGED event will not see any difference.

        * test/test_classification.py: Fix tests of ClassGroupRange
        so that they use the new signature.

        * test/test_load.py: Fix use of ClassGroupRange so that it 
        uses the new signature.

        * test/test_load_0_2.py: Fix use of ClassGroupRange so that it 
        uses the new signature.

        Import used objects/class from color.
        (generate_singletons): We don't
        need the numGroups parameter anymore because we are using
        the new ramps with GetProperties().
        (generate_uniform_distribution): Use new ramp method
        GetProperties().
        (generate_quantiles, GenQuantiles0): Use new ramp method 
        GetProperties().
        (CustomRamp.SetNumGroups): Removed. The ramps now map
        a value from 0 to 1 to class properties so the number
        of groups is not needed ahead of time.
        (CustomRamp.next): Removed. CustomRamp does not support
        interation anymore.
        (CustomRamp.GetProperties): Returns a ClassGroupProperties
        object based on the index value from 0 to 1 that is
        passed to it.
        (GreyRamp, RedRamp, GreenRamp, BlueRamp, GreenToRedRamp):
        Made into instances of Monochromatic class instread of
        deriving from it.
        (HotToCold.SetNumGroups): Removed. See CustomRamp.
        (HotToCold.next): Removed. See CustomRamp.

        * Thuban/Model/classification.py: Fixes RTbug #1973, 1971.
        (Classification.SetField, Classification.SetFieldType): 
        Replaced with SetFieldInfo.
        (Classification.SetFieldInfo): New. Does a better job of
        what SetField and SetFieldType used to do by combining
        their function since they should really always be done
        at the same time.
        (Classification.SetLayer): Renamed to _set_layer.
        (Classification._set_layer): Should only be called from
        Layer's SetClassification. This does not cause a recursive 
        call as SetLayer did because we know that Layer knows about
        the classification.

        * Thuban/Model/color.py: Fixes RTbug #1971.
        (_Transparent): Renamed from Transparent so it doesn't
        conflict with the module variable.
        (Transparent, Black): Renamed from Color.Transparent, 
        Color.Black so they are not class variables.

        * Thuban/Model/layer.py: Fixes RTbug #1971, 1973.
        (Layer.Destroy): We don't need to call SetClassification
        anymore to clear out the back reference in the classifcation
        to the layer. It's better to set it to None using _set_layer,
        and we won't be creating another clas object too.
        (Layer.SetClassification): Classification._set_layer is not
        recursive so remove all the locking variables. Also clean
        up the code so that it remains unchanged if something fails.

        * Thuban/Model/load.py: Fixes RTbug #1971.
        (SessionLoader.start_classification): Call 
        Classification.SetFieldInfo().

        * Thuban/Model/save.py: Removed import of Color which wasn't
        being used.

        * Thuban/UI/classgen.py: Fixes RTbug #1972.
        (ClassGenDialog.__init__): Color ramps are now instances 
        already so we don't need to create any new objects.
        (ClassGenDialog.OnOK): Check for numGroups is no longer 
        necessary because we never use it.

        * Thuban/UI/classifier.py: Fixes RTbug #1971.
        (Classifier.__BuildClassification, Classifier.__SetGridTable):
        Call Classification.SetFieldInfo() instead of SetFieldType.

        * Thuban/UI/renderer.py: Fixes RTbug #1971.

        * Thuban/UI/view.py: Fixes RTbug #1974, 1971.
        (MapCanvas.__init__): Subscribe to the idle time event. Set
        background color to white.
        (MapCanvas.OnPaint): Set a flag indicating that we should
        render the map during idle time. If we already have a bitmap
        just draw it now.
        (MapCanvas.OnIdle): New. Render the map only during idle time.
        This also fixes a problem with the busy cursor under gtk.

        * test/test_classgen.py (ClassGenTest.test_generate_singletons):
        Fix calls to generate_singletons because the signature changed.

        * test/test_classification.py: Fix color references and
        change calls to Classification.[SetField|SetFieldType] to
        SetFieldInfo.

        * test/test_load.py: Fix color references.

        * test/test_load_0_2.py: Fix color references.

        * test/test_save.py (SaveSessionTest.testClassifiedLayer):
        Change calls to Classification.[SetField|SetFieldType] to
        SetFieldInfo.

2003-07-01  Frank Koormann   <[email protected]>

        MERGE from the greater-ms3 branch.

        * test/test_transientdb.py
        (TestTransientTable.test_transient_joined_table_with_equal_column_names):
        New. Test join of two tables with partly equal column names.

        * Thuban/Model/transientdb.py (TransientJoinedTable.create):
        If duplicates in left and right tables column names are found, 
        append '_' (underscores) to the name until it is unique.
        Create always new internal names for the resulting table and reference
        columns in the join statement with <table>.<column>

2003-07-01  Bernhard Herzog  <[email protected]>

        * test/test_transientdb.py
        (TestTransientTable.test_transient_joined_table_same_column_name):
        New. Test whether joining on columns with the same names in both
        tables works.
        
        * Thuban/Model/transientdb.py (TransientJoinedTable.create): Make
        sure to use the right internal names even when joining on field
        with the same names in both tables. Also, detect duplicate names
        in the joined table correctly.

2003-07-01  Frank Koormann   <[email protected]>

        * Thuban/UI/renderer.py (ExportRenderer.render_legend):
        Reverse List of layers to render in same order as in desktop legend.
 
2003-06-30  Jonathan Coles   <[email protected]>

        * Thuban/version.py (make_tuple): Takes a version string
        and splits it into a tuple of at most three integers.
        Used make_tuple() to make tuple versions of the version
        numbers.

        * Thuban/UI/about.py: Add Thuban email addresses.

2003-06-30  Jonathan Coles   <[email protected]>

        * Thuban/version.py: SQLite/PySQLite version dependencies
        were too high.

2003-06-30  Jonathan Coles   <[email protected]>

        * Thuban/version.py: Update version to 0.8.1
        
        * MANIFEST.in: Added Projections so that default.proj is
        included.

2003-06-26  Jonathan Coles   <[email protected]>

        New About box with lots more information including library
        versions and credits. More/better version checking before
        Thuban starts.

        * Thuban/UI/about.py: New. New About box that displays
        library version information and credits.

        * Thuban/version.py: Added new 'versions' dictionary which
        contains the verions of various libraries which are checked
        when the module loads.
        (verify_versions): Check all version numbers and returns
        a list of errors.

        * Thuban/UI/classifier.py (Classifier.__EnableButtons):
        Reset the status of the buttons as the situation warrants,
        but in a better more reliable way by not relying on the
        current status to determine what needs to change.

        * Thuban/UI/main.py (wxCHECK_VERSION): Removed. Not needed.
        (verify_versions): Remove most of the code since it is
        now in Thuban.version.verify_versions.o

        * Thuban/UI/mainwindow.py (MainWindow.About): Call new
        About box in Thuban.UI.about.

        * extensions/thuban/gdalwarp.cpp (get_gdal_version): New.
        Returns the version of gdal library being used as a string.

        * extensions/thuban/wxproj.cpp (check_version, check_version_gtk):
        Removed.
        (get_proj_version): Return the version of PROJ that the file
        was compiled with.

2003-06-25  Jonathan Coles   <[email protected]>
 
        * Thuban/UI/classifier.py (Classifier.EditSymbol): The parent
        of the SelectPropertiesDialog should be self so the window
        appears on top.
        (ClassGroupPropertiesCtrl.DoEdit): The parent
        of the SelectPropertiesDialog should be self so the window
        appears on top.

        * Thuban/UI/resource.py: Cleaned up how we determine file
        extensions.
        (GetImageResource): Return an wxImage from our Resources.

        * Thuban/UI/renderer.py (ExportRenderer.render_legend):
        Check that a layer has a classification before trying
        to get it. Raster layers don't have classifications.

2003-06-23  Jonathan Coles   <[email protected]>
        
        * setup.py: Add Resources/XML to resource list.
    
2003-06-23  Jonathan Coles   <[email protected]>

        * setup.cfg: Fix copyright dates
    
2003-06-23  Jonathan Coles   <[email protected]>

        * MANIFEST.in: Update with Resources/XML

        * setup.py: Don't include Locale resources yet as we don't
        have any and it causes problems building the distribution
        for Windows. Update version to 0.8.0.

        * Doc/thuban.dtd: Removed since it is now in Resources/XML.

        * Thuban/UI/mainwindow.py: Add blank line at the end because
        file was not being read correctly building the Windows
        distribution.

2003-06-23  Jonathan Coles   <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.About): Fix text.

        * Thuban/version.py: Temporarily update longversion for
        the 0.8 release so that it doesn't have the cvs revision.

2003-06-23  Jonathan Coles   <[email protected]>

        * Thuban/UI/common.py (ThubanBeginBusyCursor): Call wxSafeYield
        to make sure that we don't create reentrant possibilities with
        wxYield.

        * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxBeginBusyCursor()
        directly to avoid the wxSafeYield() call which generates an 
        OnPaint event causing infinite recursion. Don't try to catch
        exception anymore. This was for before there were limits on map
        scaling.

2003-06-23  Bernhard Herzog  <[email protected]>

        Bug fix for RT #1961:

        * Thuban/Model/load.py (SessionLoader.start_derivedshapesource):
        Register DerivedShapestores with the session

        * Thuban/Model/session.py (Session.Tables): Make sure each table

2003-06-20  Bernhard Herzog  <[email protected]>

        * test/xmlsupport.py (SaxEventLister.startElementNS)
        (SaxEventLister.endElementNS): Do not include the qname. Python
        2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
        is (presumably incorrectly) None, whereas it's a string with the
        element name in the later versions.

        * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
        (TestEventList.test_even_list_namespace): Update tests to reflect

        by deriving classes to determine if that layer supports shapes.
        (Layer): Override HasShapes and return true.

        * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
        instead of a direct call to wx[Begin|End]CusyCursor().
        (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
        table data.

        * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
        New. Wrappers around the wxWindows functions that allow us to 
        make additional calls such as wxYield which gives the native 
        system a chance to update the cursor correctly.

        * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
        instead of a direct call to wx[Begin|End]CusyCursor().

        * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
        instead of a direct call to wx[Begin|End]CusyCursor().
        (MapCanvas.find_shape_at): Check if the current search layer
        support shapes, otherwise go on to the next layer.

        * test/test_layer.py: Add tests in each type of layer for
        HasClassification() and HasShapes()

2003-06-20  Jonathan Coles   <[email protected]>

        * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
        turning on the busy cursor to allow the system to change the
        cursor before we begin painting. This fixes a problem that
        was occuring only under GTK. Fixes RTbug #1840.

2003-06-20  Bernhard Herzog  <[email protected]>

        * Resources/XML/thuban-0.8.dtd: New DTD for the new file format
        version.

        * Thuban/Model/save.py (sort_data_stores): New. Make topological
        sort of the data sources so they can be written with sources that
        data sources that depend on other data sources come after the
        sources they depend on.
        (SessionSaver.__init__): Add idmap instance variable to map from
        objects to the ids used in the file.

        (SessionLoader.start_layer): Handle the shapestore attribute in
        addition to filename.

        They were never used in the old formats and aren't needed for the
        new.

        * Thuban/Model/session.py (Session.DataContainers): New method to
        return all "data containers", i.e. shapestores and tables

        * test/test_session.py
        (UnreferencedTablesTests.test_unreferenced_tables_with_joins):

2003-06-20  Jonathan Coles   <[email protected]>

        * Thuban/Model/data.py (DerivedShapeStore.__init__): Raise
        an exception if the number of shapes is different from the
        number of rows in the table. Address RTbug #1933.

        * test/test_layer.py (TestLayer.test_derived_store): Add
        a test for the new exception in DerivedShapeStore.__init__.

        * test/support.py (FloatTestCase): Removed since there is

        of test_save

2003-06-20  Bernhard Herzog  <[email protected]>

        * test/test_load.py (LoadSessionTest.check_format): New helper
        method to make sure the test files we load might have been written

        This is mainly about fixing RTbug #1949.

        * Thuban/Model/classification.py: Remove "from __future__"
        import statement since python 2.2 is the earliest supported
        version.

        * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
        Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES
        depending on the units this projection *forwards* into.

        * Thuban/Model/save.py (SessionSaver.write_classification):
        Remove unnecessary use of lambdas and nested functions.

        * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Do scale
        adjustment here if the map projection uses degrees.

        * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
        scale adjust code since it is now done before calling
        this method. Don't do anything if the map projection

2003-06-19  Bernhard Herzog  <[email protected]>

        Move version specific load tests to their own file.

        * test/test_load.py: Expand the doc-string to explain a bit how to
        handle file format changes.
        (TestClassification.test): Update the docstring as this test is
        not about Thuban 0.2 anymore.

        files created with Thuban 0.2 and earlier.

2003-06-19  Bernhard Herzog  <[email protected]>

        Add XML validation to some of the tests. Validation will only be
        done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
        To make the DTD available to the test cases it's moved into
        Resources/XML

        * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
        for versions up to and including 0.2. Two slight changes: added an
        encoding specification and fixed the comment which refered to
        GRASS, not Thuban

        * test/xmlsupport.py: New support module for tests involving XML.
        Currently there's a mix-in class for XML validation.

        * test/runtests.py (main): Call print_additional_summary instead
        of print_garbage_information

        * test/support.py (resource_dir): New function to return the
        "Resource" subdirectory
        (print_additional_summary): New function to combine several
        summary functions
        (run_tests): Use print_additional_summary instead of calling
        print_garbage_information directly

2003-06-19  Bernhard Herzog  <[email protected]>

        * Doc/thuban.dtd (classification): Correct the content model of
        the classification element.
        (projection): Add the "name" attribute

2003-06-19  Frank Koormann   <[email protected]>

        MERGE from the greater-ms3 branch.

        * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
        scale if projection is latlong to get better estimate.

        Fix problem of hidden properties dialog under windows after double
        click on layer tree:
        The tree control always gets an Expanded / Collapsed event after 
        the ItemActivated  on double click, which raises the main window again.
        We add a second ItemActivated event to the queue, which simply 
        raises the already displayed window.

        * Thuban/UI/legend.py (LegendTree.__init__): Instance variable 
        raiseProperties initialized to prevent endless loops
        (LegendTree._OnItemActivated): Depending on self.raiseProperties
        simply raise the properties or open the dialog and issue a second
        event.

2003-06-18  Jonathan Coles   <[email protected]>

        * setup.py: Fix a few problems that occured under Windows.

2003-06-18  Jonathan Coles   <[email protected]>

        When Thuban loaded the map was redrawn twice because the
        legend was being opened after the mainwindow was created
        and not during its creation. This meant the map was drawn
        initially and then had to be redrawn when the legend 
        caused the display to change. Now the legend is opened
        in the mainwindow constructor which resolves this issue.

        Also, although we were checking for the existence of 
        gdal and gdalwarp modules, the gdalwarp extension was
        still being compiled (which may fail if the system doesn't
        have gdal installed). the build_ext command to setup.py
        now accepts the flags --with-gdal and --without-gdal.
        If --without-gdal is specified setup.py will try to 
        use the gdal parameters specified by gdal-config. Under
        windows, those parameters have to be set in setup.py
        as with proj4 an wxWindows.

        * setup.py: Use a list instead of seperate variables for
        extension parameters so we can create a generic function
        that runs an appropriate *-config script.
        (run_cs_script): Renamed from run_wx_script and modified
        to accept a second argument which is a list of lists to
        be filled in by the values returned from running the command.
        (thuban_build_ext): New. Extends the build_ext command and
        provides the options --with-gdal/--without-gdal which then
        optionally includes the gdalwarp extension.

        * Thuban/Model/resource.py: First check if we can import
        the gdalwarp Thuban extension before checking for gdal.
        Also added some comments.
        
        * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
        the map is None which may be the case if none has been loaded
        yet.

        * Thuban/UI/main.py (main): Remove call to ShowLegend.

        * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().

        * Thuban/UI/renderer.py: Check for gdal support before importing
        gdalwarp.
        (MapRenderer.render_map): Only try to optimize if we have gdal
        support otherwise nothing will get drawn.

        * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called 
        during startup before a map has been created. Check if map is None 
        before using it and do nothing if it is.

2003-06-17  Jonathan Coles   <[email protected]>

        Fix the problem with raster layers under Windows that caused
        Thuban to crash. The view should respond to layer projection
        changed events to update the display. Changes to a projection
        should not cause the map to be set to full extent.
        
        * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
        current_map_proj to remember the current map projection so that
        when the projection changes we know what the previous projection
        was. 
        (MapCanvas.SetMap): Unsubscribe and subscribe to 
        LAYER_PROJECTION_CHANGED events.
        (MapCanvas.projection_changed): Split into two methods that respond
        to map and layer projection changes.
        (MapCanvas.map_projection_changed): New. Takes the current view and
        projects it using the new projection. This does not cause the
        map to be redrawn at full extent.
        (MapCanvas.layer_projection_changed): New. Cause a redraw which
        will draw each layer in its new projection.
        
        * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
        VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
        under Windows.
        
        * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
        to twice sizeof(void*) because there are two digits for each
        hex byte.

2003-06-16  Bernhard Herzog  <[email protected]>

        Update to the layer interface: Direct access to the table,
        shapetable, shapefile and filename attributes is now actively
        deprecated by issuing deprecation warnings for all places where
        this happens.

        * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
        to the instance variables table, shapetable, shapefile and
        filename via __getattr__ so that we can issue a deprecation
        warning.
        (Layer.SetShapeStore): Don't set the deprecated instance variables
        any more
        (Layer.SetShapeStore): Don't use deprecated layer instance
        variables
        (Layer.Destroy): No need to explicitly remove the instance
        variables any more
        (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
        instance variables

        * Thuban/UI/classgen.py (ClassGenDialog.__init__)
        (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
        (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
        use deprecated layer instance variables

        * Thuban/UI/classifier.py (Classifier.__init__): Don't use
        deprecated layer instance variables

        * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
        (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
        instance variables

        * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
        deprecated layer instance variables

        * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
        deprecated layer instance variables

        * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
        deprecated layer instance variables

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
        (MapRenderer.polygon_render_param): Don't use deprecated layer instance
        variables

        * test/runtests.py (main): Turn Thuban's deprecation warnings into
        errors so that they're cought by the tests

        * test/test_load.py (TestSingleLayer.test): Don't use deprecated
        layer instance variables

2003-06-16  Jonathan Coles   <[email protected]>

        Fix a problem under Windows whereby if the user double-clicks on a
        layer in the legend that tree item will expand or collapse as well
        as open the layer properties dialog. The state of the tree item
        should not be affected.

        * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
        preventExpandCollapse and subscribe to expanding and collapsing 
        events.
        (LegendTree.OnItemExpandCollapse): New. Responds to expanding and 
        collapsing events and will veto the event if it has been triggered 
        by the user double clicking on a layer.
        (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
        that an expanding/collapsing event should be vetoed.

2003-06-13  Bernhard Herzog  <[email protected]>

        * Thuban/UI/classifier.py (Classifier.OnClose)
        (Classifier.map_layers_removed)
        (Classifier.layer_shapestore_replaced): Unsubscribe the messages
        in OnClose and not in map_layers_removed or
        layer_shapestore_replaced to make sure it always happens when the
        dialog is closed

2003-06-13  Jonathan Coles   <[email protected]>

        This puts back a fix for Windows where a panel is needed so that
        the background of the table view appears correctly.

        * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
        object that can be used by derived classes to place any 
        controls (including the grid) onto.
        (QueryTableFrame.__init__): Use the panel as the parent window
        for all the controls. Reparent the grid so that the panel is
        the parent. Call UpdateStatusText() to correctly initialize
        the status bar.

2003-06-13  Jonathan Coles   <[email protected]>

        * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
        from wxFrame (as opposed to wxDialog like the other classes)
        but otherwise behaves like the other classes. This is needed
        for the TableView which isn't really a dialog and needs to
        have a status bar and control buttons.

        * Thuban/UI/tableview.py (TableGrid.__init__): Create an 
        instance variable to keep track of how many rows are selected.
        Subscribe once to the the events we are interested in.
        (ThubanGrid.OnRangeSelect): Only handle event if event handling
        hasn't been turned off.
        (ThubanGrid.OnSelectCell): Only handle event if event handling
        hasn't been turned off.
        (ThubanGrid.ToggleEventListeners): Rather than subscribe None
        as an event listener (which changes the event handler stack)
        simply set an instance variable to False. This is checked in
        the event handlers.
        (ThubanGrid.GetNumberSelected): Return the number of currently
        selected rows.
        (TableFrame): Inherit from ThubanFrame so we can have a 
        status bar and control buttons.
        (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
        Explicitly set which items are selected in the operator choice and
        action choice so there is always a valid selection. Fixes RTbug #1941.
        Subscribe to grid cell selection events so we can update the
        status bar.
        (QueryTableFrame.UpdateStatusText): Update the status bar with
        how many rows are in the grid, how many columns, and how many
        rows are selected.
        (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
        Call UpdateStatusText when cells are (de)selected.
        (QueryTableFrame.OnQuery): Use the string value in the value
        combo if either the selected item index is 0 or if the string
        cannot be found in the predefined list (this happens if the
        user changes the text). Fixes RTbug #1940.
        Only turn off the grid event listeners if there a query comes
        back with a none empty list of ids. in the case that the list
        is empty this causes a grid.ClearSelection() call to actually
        clear the grid selection which causes the selected items in
        the map to be deselected. Fixes RTbug #1939.

        * test/test_save.py (XMLWriterTest.Encode): Check return values.
        Fixes RTbug #1851.

2003-06-13  Bernhard Herzog  <[email protected]>

        * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
        self.selected_shape with the current selection to make sure the
        contents of the dialog are up to date when it's shown for the
        first time.
        The dialog used to work without this by luck. The recent fix to
        the connector module 'broke' a 'feature' the identify view was
        relying on, i.e that subscribing to a message in response to
        receiving a message of that type would mean that the new
        subscriber would also be called for the same message.
        
2003-06-12  Jonathan Coles   <[email protected]>

        * extensions/thuban/gdalwarp.cpp: Removed debug printing as
        the image is rendered. Fixes RTbug #1937.

2003-06-12  Jonathan Coles   <[email protected]>

        * Thuban/Lib/fileutil.py: As is done under Windows, create the
        user directory if it doesn't exist on a posix system. 
        Fixes RTbug #1815.

        * Thuban/Model/resource.py (get_user_proj_files): Moved the
        called to get_application_dir here, so that the directory
        will only be called if this method is invoked.

        * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
        the projfilepath if no projection is selected.

2003-06-12  Jonathan Coles   <[email protected]>

        * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
        the scalebar if the current map has no projection set.

        * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
        projfilepath label to just the basename of the projection file
        rather than include the entire path.

        * Thuban/Model/resource.py: Fix missed proj functions that 
        needed to be renamed.

2003-06-12  Jonathan Coles   <[email protected]>

        * Thuban/Model/classification.py: Removed assert statements that
        tested if the variable was an instance of Color. 

        * Thuban/Model/color.py (Color): Remove commented code that isn't
        used.
        (Transparent): Renamed from NoColor. Doesn't inherit from Color.
        Fixes RTbug #1835.
        (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
        Needed now that the class doesn't inherit from Color.

2003-06-12  Jonathan Coles   <[email protected]>

        * test/test_save.py (XMLWriterTest.testEncode): Explicitly
        check unicode strings.

        * test/test_layer.py: Check for existence of gdal.

2003-06-12  Jonathan Coles   <[email protected]>
    
        * Thuban/Model/xmlreader.py: New. Contains the XMLReader class
        that was in load.py

        * Thuban/Model/xmlwriter.py: New. Contains the XMLWriter class
        that was in save.py

2003-06-12  Jonathan Coles   <[email protected]>

        This is largely a collection of bug fixes. We also handle the
        case where gdal is not on the system. The XMLReader and XMLWriter
        classes were moved into there own files to resolve some circular
        import references and because they shouldn't really be in the
        file that is dediciated to reading/writing session files since
        they are also used elsewhere.

        * Thuban/Model/classgen.py: Renamed functions to follow the
        function_names_with_underscores style. Fixes RTbug #1903.
        (calculate_quantiles): Raise ValueError if 'percents' is invalid.

        * Thuban/Model/layer.py: Import gdal only if it available.
        (RasterLayer): Handle the case where the gdal library is unavailable.
        Addresses RTbug #1877.

        * Thuban/Model/load.py (XMLReader): Moved into seperate file
        xmlreader.py.

        when using integers versus floats.

        * Thuban/UI/mainwindow.py (_has_gdal_support): New. Used to
        determine if the "Add Image Layer" menu option should be 
        greyed out or not. Addresses RTbug #1877.

        * Thuban/UI/projdialog.py: Use renamed projection resource functions.

        * Thuban/UI/renderer.py (MapRenderer.render_map): Only try to

        * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
        once on initialisation (Former implementation resulted in multiple
        entries for each projection).
        (ProjFrame.__FillAvailList): selectProj as second optional parameter, 
        if set, select the projection found under the specified name. This 
        overwrites any other selection estimate.
        Removed projchoice filling from this method.
        (ProjFrame._OnSave, ProjFrame._OnAddToList): 
        Updated call of ProjFrame.__FillAvailList

        Do not cache the values returned by the tree widget's
        GetFirstChild and GetNextChild methods because it led to lots of
        segfaults. The new way requires more brute force but is more
        reliable.

        * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource
        acquisition has to happen before the try in a try-finally.

        RTBug #1904.

        * Thuban/UI/classifier.py: Remove unused import of ClassGenerator.

        * Thuban/UI/legend.py: The legend was cleared and repopulated any

        as which children were expanded or collapsed. Fixes RTBug #1901.
        (LegendTree._OnMsgMapLayersAdded): Add only new layers.

        with try/finally. Fixes RTBug #1904.
        (MapCanvas.FitSelectedToWindow): If a single point is selected
        simply center it on the display. Fixes RTBug #1849.

        * extensions/thuban/gdalwarp.cpp: Removed code that allowed gdalwarp
        to be compiled as a standalone app. Now the code can only be
        called from Python which simplifies the parameter passing.

        LayerTableFrame now is derived from QueryTableFrame and connects
        to a layer.

        * Thuban/UI/mainwindow.py (MainWindow.TableShow): A very coarse

        Added "outer_join = False" as optional parameter.
        (TransientJoinedTable.create): If outer join is true, perform a
        "LEFT OUTER JOIN" instead of "JOIN", which preserves all records of
        the left table. Records not matching are filled with 0 / None.

        * Thuban/UI/join.py (JoinDialog.__init__): Checkbox for outer join.
        (JoinDialog.OnJoin): Consider outer join check box.

2003-05-22  Bernhard Herzog  <[email protected]>

        somewhat safer way. Storing the traceback in a local variable can
        lead to memory leaks

2003-05-22  Bernhard Herzog  <[email protected]>

        * Thuban/UI/join.py (JoinDialog.OnJoin): Make sure to really call
        the wxMessageDialog's Destroy() method.

        * Thuban/UI/mainwindow.py (MainWindow.TableJoin): Removed print.

        * Thuban/UI/join.py (JoinDialog): Functional implementation of 
        former framework. Renamed Table1/Table2 to LeftTable/RightTable
        in all occurences.

        * Thuban/Model/transientdb.py (TransientJoinedTable.__doc__): 
        Typo fixed.

2003-05-22  Bernhard Herzog  <[email protected]>

        Give the tables titles so that the GUI can display more meaningful
        names. For now the titles are fixed but depend on e.g. filenames
        or the titles of the joined tables.

        bound to tool events.
        (LegendTree.MoveCurrentItemTop(), LegendTree.MoveCurrentItemBottom):
        New, methods binding the event methods with the map methods.

        * Thuban/Model/map.py (Map.TopLayer(), Map.BottomLayer()): New, place 
        layer at top/bottom of layer stack.

        * Resources/Bitmaps/top_layer.xpm: New button icon.

        * Resources/Bitmaps/bottom_layer.xpm: New button icon.

        (ShapefileStore.FileName, ShapefileStore.FileType): New. Accessor
        methods for filename and type
        (ShapefileStore.Dependencies): New. Implement the dependencies
        interface
        (DerivedShapeStore): New class to replace SimpleStore. The main
        difference to SimpleStore is that it depends not on a shapefile
        but another shapestore which expresses the dependencies a bit
        better
        (SimpleStore.__init__): Add deprecation warning.

        * test/test_dbf_table.py (TestDBFTable.test_dependencies): New.

        UI polishing updates: Place main buttons (OK, Cancel, etc) in the 
        lower right corner, center labels for selections, initialize controls
        in reasonable order for keyboard navigation. 

        * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
        (ProjFrame.__DoOnProjAvail): Determine position of current projection
        using the wxListBox.FindString() method. Still a problem (#1886)

        in the Field ListCtrl to the full width.
 
        * Thuban/UI/tableview.py (LayerTableFrame.__init__): Rename 'Save As'
        Button to 'Export'. Center Buttons in Selection Box, set Focus to
        Grid. 
        (LayerTableFrame.OnKeyDown()): New, bound to the grid with EVT_KEY_DOWN,
        changes focus to the Selection when pressing "Alt-S".

        * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
        the text if not visible. The italic font sometimes exceeds the
        rendering area.

2003-05-21  Jonathan Coles   <[email protected]>

        * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
        to OnClose so that Thuban closes correctly.

        * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
        DockFrame.OnClose, not DockFrame._OnClose.

2003-05-21  Jonathan Coles   <[email protected]>

        * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
        references to 'inf' and use new Range __init__ to pass floats
        directly rather than converting them to strings first. 
        Fixes RTBug #1876.

        * Thuban/Model/classification.py (ClassGroupRange.SetRange):
        Use new Range ___init__ to pass floats.

        * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
        filename is a valid image file. Throw IOError otherwise.

        * Thuban/Model/range.py: Brought over new Range from SciParam that
        is immutable and has an __init__ which can accept floats.

        * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
        into try block. AddLayer doesn't throw any exceptions anymore. 
        (MainWindow.AddRasterLayer): Move constructor of RasterLayer into 
        try block.

        * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as
        the first item in choices. Fixes RTBug #1882.

        * Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale
        has gone to 0 which is a serious problem. abort.
        (MapRenderer.draw_raster_layer): Catch IOError seperately and
        print the error from GDAL.

        to suppress excessive messages when selecting many rows. 
        Fixes RTBug #1880.

        * Thuban/UI/view.py: Added checks against if scale == 0. This
        is a serious problem that can occur when an image without 
        geo data is loading and causes the map projection bounds to
        go to infinity. Right now, the solution is to simply try
        to recover.

        * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
        to set the MFILEReceiver attributes even if the data is NULL.

        * extensions/thuban/gdalwarp.cpp: Improved the error handling
        and passed GDAL messages back up to the Python layer. Also
        tried to fix some memory leaks that were present in the original
        utility but didn't matter because the program aborted.

        * test/test_range.py: Copied over tests from SciParam. Removed
        tests against importing. Fixes RTBug #1867.

2003-05-21  Bernhard Herzog  <[email protected]>

        filled transparent to have the raster image visible at once.

2003-05-21  Frank Koormann  <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to 
        OnClose() to keep in sync with extensions. Internally Thuban
        still uses "underscored" names.

2003-05-20  Jonathan Coles   <[email protected]>

        This puts back Raster layer support. These layers support projections
        through the GDAL library. Currently, the CVS version is being used.
        There are no Debian packages available although this may change soon. 
        A GDAL driver was extended to support writing to memory rather to
        files.

        There is still some work that needs to be done, such as some error
        handling when loading invalid images or when there is a problem
        projecting the image. This putback simply checks in the majority
        of the work.

        * setup.py: Add gdalwarp library extension.

        * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
        Defaults to False, but can be overridden by subclasses if they

        (RasterLayer): New. Defines a new layer that represents an
        image.

        * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
        tag handler.
        (SessionLoader.start_layer): Encode the filename.
        (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
        New. Supports reading a rasterlayer tag.

        * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.

        * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
        get a string in Latin1. If we get such as string convert it to
        unicode first, otherwise leave if alone before encoding.
        (SessionSaver.write_layer): Add support for writing both Layers
        and RasterLayers.

        * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery): 
        The right argument may not be a string, it could also be a Column.

        * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
        Make initial window size 600x400. Fixes RTBug #1872.

        * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
        the dialog is constructed so that we can support layers that
        do not have classifications.
        (Classifier._OnTry): Only build a classification if the layer
        supports one.

        * Thuban/UI/legend.py: Change all checks that a layer is an
        instance of Layer into checks against BaseLayer.
        (LegendTree.__FillTreeLayer): Only add children to a branch if
        the layer supports classification.

        * Thuban/UI/mainwindow.py (MainWindow.NewSession,
        MainWindow.OpenSession): Don't proceed with an action if the 
        user chooses Cancel when they are asked to save changes.
        (MainWindow.AddRasterLayer): New. Open a dialog to allow the
        user to select an image file. Create a new RasterLayer and add
        it to the map.

        * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
        for rendering RasterLayer layers.
        (MapRenderer.draw_raster_layer): Actually method that calls
        the GDALWarp python wrapper and constructs an image from the
        data returned.

        * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the
        Choices symbols to match those used in the table query method.
        Replace deprecated method calls on table with new method names.

        * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
        how small the scale can get. This still needs more testing.

        * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
        Provides a driver to output in .bmp format.

        * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h: 
        New. Provides IO routines which write to memory, rather than a file.

        * extensions/thuban/gdalwarp.cpp: New, but basically a direct copy
        of the gdalwarp utility provided in GDAL. Added function calls
        that can be accessed from python.

        * Data/iceland_sample_raster.thuban: New. Sample file that uses
        a raster layer.

        * Data/iceland/island.tfw, Data/iceland/island.tif: New. Raster
        layer image data.

        * Doc/thuban.dtd: Added rasterlayer attribute definition.

        * test/test_layer.py, test/test_load.py, test/test_save.py: Added
        tests associated with the raster layer code.

        * test/test_transientdb.py
        (TestTransientTable.test_auto_transient_table_query): Added a test 
        for using a Column object as the "right" parameter to a query.

2003-05-19  Frank Koormann  <[email protected]>

        * Thuban/version.py (get_changelog_date): 
        Catch exceptions if ChangeLog does not exist.

        information: Display Thuban, wxPython and Python version.

2003-05-16  Bernhard Herzog  <[email protected]>

        * Thuban/Model/save.py: Remove some unused imports including the
        __future__ import for nested_scopes as Thuban relies on Python 2.2
        now.
        (XMLWriter.encode): Remove the special case for a None argument.
        In the saver encode is always called with a string argument.

2003-05-16  Bernhard Herzog  <[email protected]>

        * Thuban/UI/__init__.py: Remove the work-around for the locale bug
        in wxPython (at least when usinvg wxGTK) prior to 2.4. The symptom
        of the bug was that e.g. float("1.2") would fail. Thuban now
        requires 2.4.x.
        
2003-05-16  Frank Koormann   <[email protected]>

        Printing enhancement and WMF export (under Win32)

2003-05-14  Jonathan Coles   <[email protected]>

        * Thuban/Model/classgen.py (ClassGenerator.GenSingletonsFromList):
        Fix docstring.
        (ClassGenerator.GenUniformDistribution): Fix spelling of method name.
        (ClassGenerator.GenQuantiles): Use the left/right brackets and min/max

        bounds of the generated classes.

        * Thuban/Model/range.py (Range.number_re): Now accepts floats that
        do not have a leading 0 (.5 is now accepted as well as 0.5).

        * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Replace call
        to table.UniqueValues() with calls that retrieve all the values

        which can simply return the list (perhaps more efficiently).

2003-05-12  Jonathan Coles   <[email protected]>

        The return value of ClassGenerator.CalculateQuantiles has changed.
        Refer to the documentation for details.

        * test/test_classgen.py: Modified Quantile tests to use the
        new return values.

        * Thuban/Model/classgen.py 
        (ClassGenerator.GenQuantiles): Add comments describing the parameters,
        use new return values from CalculateQuantiles to produce the correct 
        range bounds in the Classification.
        (ClassGenerator.CalculateQuantiles): Add more comments describing
        the return values and parameters. Make minor adjustments to improve
        the legibility of the code. Fix problem with adjusted not being set

        Introduces Range class from SciParam into the ClassGroupRange class,
        and such ranges can now be saved and loaded from disk.

        Quantiles are now available in the Classification Generator.

        Initial support for building Queries on a table. Doesn't do anything
        but run some tests.

        * Thuban/Model/classification.py: Explicit imports.
        (ClassGroupRange): Use the Range class to store the underlying
        range information. The interface remains the same, except for
        GetRange(), and you can also supply a Range object as the min 
        parameter to SetRange or __init__.

        * Thuban/Model/load.py (XMLReader.encode): New. Encodes the given
        string appropriately for use in Thuban. Fixes RTbug #1851.

        projection tag a bit better by looking at what objects are not
        None. There was an assumption that a projection tag for a map
        could occur before any layers.
        (SessionLoader.start_clrange): Provide backward compatibility for
        reading min/max values as well as the new range parameter.

        selecting multiple shapes.
        (LayerTableFrame): Support for building Queries.

        table view can call it.

        * test/test_classification.py: Explicit imports.
        (TestClassification.test_ClassGroupRange): Fix test for new
        Range class.

        * Doc/thuban.dtd: Add range parameter for clrange.

        * Thuban/Model/range.py: Taken from SciParam. Used as the underlying
        object in ClassGroupRange, and also uesd for inputting ranges in

        SimpleQuery method

2003-05-06  Bernhard Herzog  <[email protected]>

        Convert all table users to use the new table interface. This only
        covers Thuban itself, not GREAT-ER or other applications built on
        Thuban yet, so the compatibility interface stays in place for the
        time being but it now issues DeprecationWarnings.

        Finally, the new Table interface has a new method, HasColumn.

        * Thuban/Model/table.py (OldTableInterfaceMixin): All methods
        issue deprecation warnings when they're. The warnings refer to the
        caller of the method.
        (OldTableInterfaceMixin.__deprecation_warning): New. Helper method
        for the deprecation warnings

        * test/test_table.py: Ignore the deprecation warnings for the old
        table in the tests in this module. The purpose of the tests is to
        test the old interface, after all.

        * test/test_transientdb.py
        (TestTransientTable.run_iceland_political_tests): Use the
        constants for the types. Add a test for HasColumn

        * test/test_layer.py (TestLayer.open_shapefile): Helper method to
        simplify opening shapefiles a bit easier.
        (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
        (TestLayer.test_point_layer): Use the new helper method
        (TestLayer.test_get_field_type): New. Test for the GetFieldType

        Addresses the "Selection Extent" wish of RTbug #1787.

        * Resources/Bitmaps/fulllayerextent.xpm,
        Resources/Bitmaps/fullselextent.xpm: Bitmaps for layer and selection
        extent. These are just place holders for the real bitmaps.

        * Thuban/Model/layer.py (Shape): Since a Shape is immutable only
        calculate the bounding box once (the first time compute_bbox() is 
        called).
        (Layer.ShapesBoundingBox): New. Given a list of shape ids, return
        the bounding box for the shapes in lat/long coordinates. 

        * Thuban/UI/mainwindow.py: Added new "Full selection extent" menu
        option.
        (MainWindow.has_selected_shapes): New. Returns true if there are

        (MainWindow.FullSelectionExtent): New. Calls 
        MapCanvas.FitSelectedToWindow() when the user selects the menu option.
        (_has_selected_shapes): New. Returns true if there are any 
        selected shapes.

        true if there are any selected shapes.

        * Thuban/UI/view.py (MapCanvas): Added delegated method
        HasSelectedShapes.
        (MapCanvas.FitSelectedToWindow): New. Centers and scales any selected
        shapes on the canvas using the map projection (if any).

        Convert the table implementations to a new table interface. All
        tables use a common mixin class to provide backwards compatibility
        until all table users have been updated.

        * Thuban/Model/table.py (OldTableInterfaceMixin): Mixin class to
        provide backwards compatibility for table classes implementing the
        new interface
        (DBFTable, MemoryTable): Implement the new table interface. Use
        OldTableInterfaceMixin as base for compatibility
        (DBFColumn, MemoryColumn): New. Column description for DBFTable
        and MemoryTable resp.

        * test/test_dbf_table.py: New. Test cases for the DBFTable with
        the new table interface.

        * test/test_memory_table.py: New. Test cases for the MemoryTable
        with the new table interface.

        * test/test_table.py: Document the all tests in this file as only
        for backwards compatibility. The equivalent tests for the new
        interface are in test_memory_table.py and test_dbf_table.py
        (MemoryTableTest.test_read): field_info should be returning tuples
        with four items
        (MemoryTableTest.test_write): Make doc-string a more precise.

        * Thuban/Model/transientdb.py (TransientTableBase): Convert to new
        table interface. Derive from from OldTableInterfaceMixin for
        compatibility.
        (TransientTableBase.create): New intance variable column_map to
        map from names and indices to column objects
        (TransientTable.create): Use the new table interface of the input
        table
        (AutoTransientTable): Convert to new table interface. Derive from

        (AutoTransientTable.write_record): Removed. It's not implemented
        yet and we still have to decide how to handle writing with the new
        table and data framework.

        * test/test_transientdb.py
        (TestTransientTable.run_iceland_political_tests)
        (TestTransientTable.test_transient_joined_table): Use the new
        table interface

2003-05-05  Jonathan Coles   <[email protected]>

        This is namely a collection of UI updates to improve user interactivity.
        Tabbing between controls now exists and you can use ESC to close dialog
        boxes; ENTER will active the default button.

        * Thuban/UI/classgen.py (ClassGenDialog.__init__): Rearrange the
        order that the controls are created so that tabbing works correctly. 
        (ClassGenDialog.OnOK): Renamed from _OnGenerate() so that the 
        wxDialog can handle the default button correctly.
        (ClassGenDialog.OnCancel): Renamed from _OnCloseBtn() for the
        same reasons as for OnOK.
        (GenUniformPanel._OnRetrieve): Call wxBeginBusyCursor/wxEndBusyCursor
        when we ask the table for the maximum/minimum values of a field
        which could take a very long time.

        * Thuban/UI/classifier.py (Classifier.__init__): Rearrange the
        order that the controls are created so that tabbing works correctly.
        (SelectPropertiesDialog.__init__): Rearrange the order that the 
        controls are created so that tabbing works correctly.

        * Thuban/UI/dialogs.py: Copied NonModalDialog box and changed it
        to derive from a wxDialog but behave like the original implementation
        which was derived from a wxFrame. wxDialog provides useful key
        handling functionality like ESC calling OnCancel and ENTER calling
        OnOK which is lost with wxFrame.

        * Thuban/UI/mainwindow.py: Add "..." to menu items that will open
        new dialogs.

        * Thuban/UI/projdialog.py (ProjFrame.__init__): Rearrange the
        order that the controls are created so that tabbing works correctly.
        (ProjFrame.OnApply): Renamed from _OnTry() to use wxDialog behaviour.
        (ProjFrame.OnOK): Renamed from _OnOK() to use wxDialog behaviour.
        (ProjFrame.OnCancel): Renamed from _OnClose() to use wxDialog behaviour.
        (ProjPanel.__init__): Add "Airy" to the list of ellipsoids so we
        can provide the "UK National Grid" as a default projection.
        (UTMPanel.__init__): Rearrange the order that the controls are 
        created so that tabbing works correctly.

2003-05-05  Bernhard Herzog  <[email protected]>

        * extensions/thuban/wxproj.cpp: Fix some of the comments.
        (project_point): If a map projection but no layer projection is
        given, convert degrees to radians before applying the map
        projection.

        * Thuban/UI/tableview.py (TableGrid.disallow_messages)
        (TableGrid.allow_messages): New methods to make it possible to
        inhibit message sending.
        (TableGrid.issue): Only send the message if not inhibited.
        (LayerTableGrid.select_shape): Use the new methods to make sure
        that no ROW_SELECTED message is sent while we're updating the
        selected rows to match the selected shapes.

2003-05-02  Jan-Oliver Wagner <[email protected]>

        Implementation of MemoryTable.

        * Thuban/Model/table.py (MemoryTable): New. Quite simple table
        implementation that operates on a list of tuples. All of the data
        are kept in the memory.

        * test/test_table.py (MemoryTableTest): New.

        * test/test_transientdb.py (SimpleTable): Removed.
        (TestTransientTable.test_transient_joined_table,
        (TestTransientTable.test_transient_table_read_twice): Replaced
        SimpleTable by MemoryTable.

2003-04-30  Jonathan Coles   <[email protected]>

        * Data/iceland_sample.thuban: Now contains correct projections
        for each of the layers.

        * Resources/Projections/defaults.proj: Geographic projection
        contains unit conversion parameter.

2003-04-30  Jonathan Coles   <[email protected]>

        The most important part of this putback is the projection changes.
        It should now be possible to specify the projection that a layer
        is in and then specify a different projection for the map. The
        projection dialog has an extra parameter for a geographic projection
        which lets the user select if the input is in degrees or radians.

        * Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring
        to say that the parameter is a tuple of unprojected 
        points (which is what the callers to this method were assuming).
        Also, since the points are unprojected we need to projected them.

        * Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp, 
        LegendTree.MoveCurrentItemDown): If the layer or any of the layer's
        groups are selected, move the layer up/down. Fixes RTbug #1833.

        * Thuban/UI/mainwindow.py: Move menu item map_rename up.

        * Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing 
        parameter in call to SetClientData.
        (GeoPanel): Add support for selecting the units that the
        source data is in (Radians or Degrees).

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize
        the rendering loop by reducing the number of if's, removing the
        unnecessary try/except block, and checking if the old group
        is the same as the new one (which happens a lot if there is 
        no classification, or lots of shapes are in the same group).

        * Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block
        around the redraw routine to try to catch problems that the user
        may create by selecting invalid projections for the data set and
        map. Clears the display if there are any problems and prints the
        error.
        (MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled
        rectangle.

        * extensions/thuban/wxproj.cpp (project_point): First invert the
        supplied point (which should be in projected coordinates) using
        the layer's projection and then project the point using the
        map's projection.
        (project_points): Use project_point() to project each point.

2003-04-30  Jan-Oliver Wagner <[email protected]>

        * Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug:
        don't set the Classification to None if the classfication field
        is None (ie only a DEFAULT).

2003-04-30  Bernhard Herzog  <[email protected]>

        * Thuban/UI/view.py: Fix some typos.

        * Thuban/UI/mainwindow.py (MainWindow.identify_view_on_demand): Do
        not pop up the dialog if the selection becomes empty (this could
        happen if e.g. a new selection is opened while the identify tool
        is active and dialog had been closed)

2003-04-30  Bernhard Herzog  <[email protected]>

        * Thuban/Model/transientdb.py (TransientTableBase.__init__): New
        instance variable read_record_last_result
        (TransientTableBase.read_record): Make sure reading the same
        record twice works. The implementation uses the new instance
        variable read_record_last_result

        * test/test_transientdb.py
        (TestTransientTable.test_transient_table_read_twice): New test
        case for the above bug-fix.

2003-04-29  Jonathan Coles   <[email protected]>

        * Thuban/common.py: Removed. No longer needed Str2Num. RTbug #1832.

        * Thuban/UI/classgen.py: Remove all uses of Str2Num.

        * Thuban/UI/classifier.py: Remove all uses of Str2Num.
        (ClassTable.SetValueAsCustom): Rename keyword argument in 
        ClassGroup* constructors to match argument name.

2003-04-29  Bernhard Herzog  <[email protected]>

        * Thuban/Model/session.py (Session.Destroy): Explicitly close the
        transient DB if it exists to make sure it doesn't leave a journal
        file in the temp directory.

        * Thuban/Model/transientdb.py (TransientDatabase.close): Set
        self.conn to None after closing the connection to make sure it's
        not closed twice

2003-04-29  Jonathan Coles   <[email protected]>

        Add a visible parameter in the layer XML tag. The default value is
        "true". If anything other than "false" is specified we also assume
        "true". Addresses RTbug #1025.

        * Doc/thuban.dtd: Add visible parameter to a layer.

        * Thuban/Model/layer.py (BaseLayer.__init__): Change default value
        of visible from 1 to True.
        (Layer.__init__): Change default value of visible from 1 to True.

        * Thuban/Model/load.py (SessionLoader.start_layer): Read visible
        parameter.

        * Thuban/Model/save.py (SessionSaver.write_layer): Save visible
        parameter.

        is loaded correctly.

        * test/test_save.py (SaveSessionTest.testSingleLayer): Add test
        for saving an invisible layer.

2003-04-29  Jonathan Coles   <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.SetMap): Look up the
        legend dialog box and tell it to change its map to the one
        supplied to SetMap(). Fixes RTbug #1770.

2003-04-29  Bernhard Herzog  <[email protected]>

        Next step of table implementation. Introduce a transient database
        using SQLite that some of the data is copied to on demand. This
        allows us to do joins and other operations that require an index
        for good performance with reasonable efficiency. Thuban now needs
        SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I
        haven't tested that.
        
        * Thuban/Model/transientdb.py: New. Transient database
        implementation.

        * test/test_transientdb.py: New. Tests for the transient DB
        classes.

        * Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New
        classes to help automatically remove temporary files and
        directories.
        (Session.__init__): New instance variables temp_dir for the
        temporary directory and transient_db for the SQLite database
        (Session.temp_directory): New. Create a temporary directory if not
        yet done and return its name. Use AutoRemoveDir to have it
        automatically deleted
        (Session.TransientDB): Instantiate the transient database if not
        done yet and return it.

        * Thuban/Model/data.py (ShapefileStore.__init__): Use an
        AutoTransientTable so that data is copied to the transient DB on
        demand.
        (SimpleStore): New class that simply combines a table and a
        shapefile

        * Thuban/Model/table.py (Table, DBFTable): Rename Table into
        DBFTable and update its doc-string to reflect the fact that this
        is only the table interface to a DBF file. Table is now an alias
        for DBFTable for temporary backwards compatibility.

        * Thuban/UI/application.py (ThubanApplication.OnExit): Make sure
        the last reference to the session goes away so that the temporary
        files are removed properly.

        * test/test_load.py (LoadSessionTest.tearDown): Remove the
        reference to the session to make sure the temporary files are
        removed.

2003-04-29  Bernhard Herzog  <[email protected]>

        * Thuban/Model/load.py (XMLReader.__init__, XMLReader.read): Turn
        the __parser instance variable into a normal local variable in
        read. It's only used there and read will never be called more than
        once. Plus it introduces a reference cycle that keeps can keep the
        session object alive for a long time.

2003-04-29  Jonathan Coles   <[email protected]>

        * Thuban/Model/proj.py (Projection): Removed Set*() methods to make 
        Projection an immutable item. Fixes RTbug #1825. 
        (Projection.__init__): Initialize instance variables here.
        (ProjFile.Replace): New. Replace the given projection object with
        the new projection object. This solves the problem of needing the 
        mutator Projection.SetProjection() in the ProjFrame class and
        allows a projection to change parameters without changing its 
        location in the file.

        * Thuban/UI/mainwindow.py (MainWindow.SaveSessionAs): Dialog should
        be of type wxSAVE and should verify overwriting a file.

        * Thuban/UI/projdialog.py (ProjFrame._OnSave): Use the new 
        ProjFile.Replace() method instead of the mutator 
        Projection.SetProjection(). Also requires that we reassign the
        client data to the new projection.

        * test/test_proj.py (TestProjection.test): Test GetName() and
        GetAllParameters()
        (TestProjFile.test): Remove tests for Set*() methods. Add tests
        for Replace().

2003-04-25  Jonathan Coles   <[email protected]>

        * Thuban/Model/save.py (SessionSaver.write_projection): Make sure
        to save the name of the projection.

        * test/test_save.py (SaveSessionTest.testLayerProjection): New
        test to verify layer projections are saved correctly.

2003-04-25  Jonathan Coles   <[email protected]>

        * Thuban/Model/proj.py (Projection.SetName): Set the name
        to "Unknown" if name is None.
        (Projection.SetAllParameters): New. Set the projection's
        parameter list to the one supplied.
        (Projection.SetProjection): New. Set the projection's 
        properties to those of the supplied Projection.

        * Thuban/UI/mainwindow.py (MainWindow.MapProjection): Set
        the dialog title to include the map's title.
        (MainWindow.LayerProjection): Set the dialog title to include
        the layer's title.

        * Thuban/UI/projdialog.py (ProjFrame.__ShowError): Consolidate
        error dialogs into a single method call.
        (ProjFrame.__VerifyButtons): Add more states to check.
        (ProjFrame.__GetProjection): Return the current state of an
        edited projection or None.
        (ProjFrame.__FillAvailList): Remove checks for states that
        shouldn't exist.
        (ProjFrame._OnNew): Clear all selected items and supply
        a projection panel if necessary.

        * test/test_proj.py (TestProjFile.test): Add tests for
        ProjFile.SetAllParameters, ProjFile.SetProjection,
        ProjFile.SetName.

2003-04-25  Jonathan Coles   <[email protected]>

        * Thuban/UI/projdialog.py (ProjFrame.__FillAvailList): Now 
        takes an optional argument to select the current projection.
        This does not guarantee that the item is visible due to
        limited wxWindows functionality. Fixes RTBug #1821.

2003-04-25  Jonathan Coles   <[email protected]>

        * Thuban/Model/load.py (SessionLoader.start_projection): Remember
        the projection name and use it when constructing the Projection
        object.

        * Thuban/Model/proj.py (Projection.__init__): Change the default
        value for 'name' to None and then test if name is equal to None
        in the body of the constructor. This way the caller doesn't have to
        know what the default value should be. Namely, useful in load.py 
        where we have to pick a default value if the 'name' parameter
        doesn't exist in the XML file.

        * test/test_load.py (LoadSessionTest.testLayerProjection): New.
        Tests a file where a layer has a projection.

2003-04-25  Jonathan Coles   <[email protected]>

        * Thuban/Model/layer.py (Layer.TreeInfo): Add an item to the
        tree for projection information.

        * Thuban/Model/load.py (XMLReader.GetFilename): Renamed from 
        XMLReader.GetFileName.
        (SessionLoader): Added support for loading projection tags that
        appear inside a layer.

        * Thuban/Model/proj.py (ProjFile): Document the class. Move 
        back to using a list because the order of the projections in 
        the file is important to maintain. Fixes RTbug #1817.

        * Thuban/Model/resource.py: Rename calls to ProjFile.GetFileName
        to ProjFile.GetFilename.

        * Thuban/Model/save.py (SessionSaver.write_layer): Save projection
        information.

        * Thuban/UI/projdialog.py (ProjFrame._OnAddToList): Renamed from
        ProjFrame._OnSaveAs. Removed old dead code from previous
        implementation.
        (ProjFrame._OnExport): Add support for exporting more than one
        projection to a single file.
        (ProjFrame.__FillAvailList): use string formatting (% operator) 
        to build strings that are (partly) translated. Fixes RTbug #1818.

        * test/test_proj.py (TestProjFile.test): New. Tests the base ProjFile
        class.

2003-04-24  Bernhard Herzog  <[email protected]>

        * po/es.po: Updated Spanish translation by Daniel Calvelo Aros

        * po/fr.po: New. French translation by Daniel Calvelo Aros

        * Thuban/UI/projdialog.py (ProjFrame._OnSaveAs): Don't translate
        empty strings.

2003-04-24  Jonathan Coles   <[email protected]>

        * Thuban/Model/layer.py (Layer.GetProjection): New. Needed to
        implement the interface that the ProjFrame dialog expects.

        * Thuban/Model/proj.py (Projection.SetName): New. Allows the
        name of the projection to be changed.
        (ProjFile): Use a dictionary instead of a list so that removing
        projections is easier and we are sure about uniqueness.
        (ProjFile.Remove): Remove the given projection object.

        * Thuban/Model/resource.py (GetSystemProjFiles, GetUserProjFiles): 
        Return a list with only one projection file instead of searching for 
        any projection file. This simplifies many things if the user can
        only have one system file and one user file.

        * Thuban/UI/classgen.py: Change all references to 
        genCombo to genChoice.

        * Thuban/UI/mainwindow.py: Add a Projection option under the
        layer menu.
        (MainWindow.LayerProjection): New. Open up a projection window
        for a layer.

        * Thuban/UI/projdialog.py: Large changes to how the dialog is
        laid out. Use three panels instead of one. One for the list of
        projections, one for the edit controls, and one for the buttons.
        Fixed resizing problems so that the dialog resizes correctly
        when the projection panel changes. Added import/export, save, and
        new buttons/functionality.

2003-04-24  Bernhard Herzog  <[email protected]>

        First step towards table management. Introduce a simple data
        abstraction so that we replace the data a layer uses more easily
        in the next step.

        * Thuban/Model/data.py: New file with a simple data abstraction
        that bundles shapefile and dbffile into one object.

        * Thuban/Model/session.py (Session.OpenShapefile): New method to
        open shapefiles and return a shape store object

        * Thuban/Model/layer.py (Layer.__init__): Pass the data as a store
        object instead of a shapefile filename. This introduces a new

        backwards compatibility keep the old instance variables.
        (open_shapefile): Removed. No longer needed with the shape store.
        (Layer.SetShapeStore, Layer.ShapeStore): New methods to set and
        get the shape store used by a layer.

        OpenShapefile method to open shapefiles and build the filename in
        a more platform independed way

        * test/test_layer.py (TestLayer.setUp, TestLayer.tearDown):
        Implement to have a session to use in the tests
        (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
        (TestLayer.test_point_layer, TestLayer.test_empty_layer): Use the
        session's OpenShapefile method to open shapefiles
        (TestLayerLegend.setUp): Instantiate a session so that we can use
        it to open shapefiles.
        (TestLayerLegend.tearDown): Make sure that all references to
        layers and session are removed otherwise we may get a resource
        leak

        * test/test_map.py (TestMapAddLayer.test_add_layer)
        (TestMapWithContents.setUp): Instantiate a session so that we can
        use it to open shapefiles.

        resource leak
        ("__main__"): use support.run_tests() so that more info about
        uncollected garbage is printed

        * test/test_save.py (SaveSessionTest.testSingleLayer): Use the
        session's OpenShapefile method to open shapefiles
        ("__main__"): use support.run_tests() so that more info about
        uncollected garbage is printed

        * test/test_selection.py (TestSelection.tearDown): Make sure that
        all references to the session and the selection are removed
        otherwise we may get a resource leak
        (TestSelection.get_layer): Instantiate a session so that we can
        use it to open shapefiles.
        ("__main__"): use support.run_tests() so that more info about
        uncollected garbage is printed

        * test/test_session.py (TestSessionBase.tearDown)
        (TestSessionWithContent.tearDown): Make sure that all references
        to the session and layers are removed otherwise we may get a
        resource leak
        (TestSessionWithContent.setUp): Use the session's OpenShapefile
        method to open shapefiles

2003-04-24  Jonathan Coles   <[email protected]>

        * Thuban/Model/load.py (XMLReader.read): Should have been checking
        if the file_or_filename object had the 'read' attribute.

2003-04-23  Jonathan Coles   <[email protected]>

        * Thuban/Model/resource.py: Fixes RTbug #1813.
        (ReadProjFile): Add documentation about which exceptions are raised. 
        Always pass the exceptions up to the caller.
        (GetProjFiles): If the directory can't be read return an empty list.
        If any of the proj files can't be read skip that file and go
        on to the next one.

        * test/test_proj.py: Added test cases to handle nonexistent files,
        unreadable files, and files that don't parse correctly.

2003-04-23  Jonathan Coles   <[email protected]>

        Projection dialog. Allows the user to select from a list
        of projection templates and optionally edit them and save new ones.

        * Thuban/UI/projdialog.py (ProjFrame): New. Main dialog.
        (ProjPanel): Base class for projection specific panels.
        (TMPanel): Projection panel for Transverse Mercartor.
        (UTMPanel): Projection panel for Universal Transverse Mercartor.
        (LCCPanel): Projection panel for Lambert Conic Conformal.
        (GeoPanel): Projetion panel for Geographic Projection.

2003-04-23  Jonathan Coles   <[email protected]>

        * Thuban/Model/load.py (XMLReader): Renamed from XMLProcessor to
        promote symmetry. There now exists XMLReader and XMLWriter.
        (XMLReader.read): New. Call to read the given file descriptor or
        filename.
        (XMLReader.close): New. Make sure the file is closed.
        (XMLReader.GetFileName): New. Return just the file name that is being
        read from.
        (XMLReader.GetDirectory): New. Return just the directory of the file
        that is being read.
        (XMLReader.AddDispatchers): New. Take a dictionary which contains
        the names of functions to call as the XML tree is parsed.
        (XMLReader.startElementNS): Updated to use new dispatcher dictionary.
        (XMLReader.endElementNS): Updated to use new dispatcher dictionary.
        (SessionLoader): Removed class variables start_dispatcher and
        end_dispatcher since this functionality is now part of a class
        instance. Fixes RTbug #1808.
        (SessionLoader.__init__): Add dispatcher functions.
        (load_xmlfile): Code was moved into the XMLReader.read().
        (load_session): Use modified SessionLoader.

        * Thuban/Model/map.py (Map.GetProjection): New. Returns the 
        map's projection.

        * Thuban/Model/proj.py (Projection.GetParameters): Renamed to 
        GetAllParameters. 
        (Projection.GetParameter): Returns the value for the given parameter.

        promote symmetry.

        * Thuban/UI/classgen.py (ClassGenDialog.__init__): Use a wxChoice
        control instead of a wxComboBox. wxChoice controls do not generate
        events as the uses highlights possible choices which fixes problems
        with resizing the dialog when the use selects an option.

        * Thuban/UI/classifier.py (Classifier.__init__): Use a wxChoice
        control instead of a wxComboBox.

        anymore.
        (Layer.BoundingBox, Layer.GetFieldType, Layer.NumShapes)
        (Layer.ShapeType, Layer.Shape): No need to call
        self.open_shapefile since it's always called in __init__

        * Thuban/UI/application.py (ThubanApplication.MainLoop): Removed.
        In wxPython 2.4 there's no need to extend MainLoop anymore since
        wxPython itself makes sure OnExit is called.

2003-04-16  Jonathan Coles   <[email protected]>

        Initial putback of projection management code. Includes new
        classes to read and write projection files. The current load
        and save classes were abstracted a bit so they could be reused.
        The Projection class was extended to provide new methods and
        have a name.

        * Thuban/Model/load.py (XMLProcessor): New. Contains all the
        general XML reading methods that were part of ProcessSession.

        * Thuban/Model/proj.py (Projection.__init__): Accepts an optional
        name.
        (ProjFile): New. Represents a file that contains projection
        information.

        * extensions/thuban/wxproj.cpp (extract_projection)
        (extract_pointer): Rename extract_projection to extract_pointer
        and redefine its purpose to return the pointer stored in a CObject
        returned by the object's cobject method. Update all callers.
        (s_draw_info, free_draw_info, draw_polygon_init): Implement the
        handling of these low-level parameters so that each s_draw_info
        instance is handled as a CObject at python level that also
        contains real references to the actual python objects which
        contain the values in the struct. Add free_draw_info as the
        destructor.
        (draw_polygon_shape): Add the py_draw_info parameter which must a
        cobject containing an s_draw_info pointer.

        * extensions/thuban/wxproj.cpp (draw_polygon_init): New. Used
        to improve rendering performance by initializing the variables
        that are not change each time draw_polygon_shape() is called.
        The values are stored in a global struct draw_info.

        now in draw_polygon_init().

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Make

        weirdness by setting the range to (1, maxint).

        * Thuban/Model/classification.py (ClassGroupProperties): Make
        instance variables private and optimize comparison operator
        by first checking if the color references are the same.
        (ClassGroupSingleton): Make instance variables private.

        same place as it was when it was closed.
        (DockableWindow.Destroy): Call renamed method OnDockDestroy().
        (DockableWindow._OnButtonClose): Hide the window instead of

2003-04-07  Jonathan Coles   <[email protected]>

        Since we now say that the order of the groups in a classification
        matters, it makes sense to be able to manipulate that order. Most
        of the changes to Thuban/Model/classification.py are to that end.

        * Thuban/Model/classification.py (Classification.AppendGroup,
        Classification.InsertGroup, Classification.ReplaceGroup,
        Classification.RemoveGroup, Classification.GetGroup): Do as the
        names imply.
        (Classification.FindGroup): This was called GetGroup, but GetGroup
        takes an index, while FindGroup takes a value.
        (Classification.__deepcopy__): Copy all the groups, BUT NOT THE LAYER
        REFERENCE. Currently there is a cyclic reference between the layer
        and its classification. If the classification doesn't need to know
        its owning layer we can change this, since it may make sense to be
        able to use the same classification with different layers.

        * Thuban/Model/load.py: Use Classification.AppendGroup(), not AddGroup()

        * Thuban/UI/classgen.py: Use Classification.AppendGroup(), 
        not AddGroup()

        * Thuban/UI/classifier.py: Now that we can depend on the order in 
        a Classification and have methods to manipulate that order we don't
        need to use our own data structures in the grid. We can simply make
        the grid/table access the information they need from a copy of 
        the classification object.
        (Classifier._OnCloseBtn): Event handler for when the user clicks
        'Close'. This is needed so if the user applies changes and then
        continues to change the table the user has the option of discarding
        the most recent changes and keeping what they applied.

        * Thuban/UI/mainwindow.py: Put "Show Legend" and "Show Session Tree"
        into the same group.

        * extensions/thuban/wxproj.cpp (check_version): If Thuban is compiled
        with a really old version of proj, PJ_VERSION won't even be defined.
        If it isn't defined then just compile so that the function always
        returns Py_False.

        * test/test_classification.py: Fix tests to use the renamed methods.
        Still need to write tests for the new methods.

2003-04-04  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py (Classifier.__SelectField): Move the
        call to SetSelection out of the method and before the call
        to __SelectField in __init__. This prevents a recursion of events
        when _OnFieldSelect is triggered by the user.

2003-04-04  Jonathan Coles   <[email protected]>

        * Thuban/Model/classification.py: Rename Color.None to 
        Color.Transparent.
        (ClassGroupProperties.SetLineColori, ClassGroupProperties.SetFill): 
        Don't bother copying the color, since Colors are immutable.

        * Thuban/Model/color.py, Thuban/Model/layer.py, Thuban/Model/load.py,
        Thuban/UI/classifier.py, Thuban/UI/mainwindow.py,
        Thuban/UI/renderer.py, Thuban/UI/view.py:
        Rename Color.None to Color.Transparent.
    
        * test/test_classification.py, test/test_load.py: Rename Color.None 
        to Color.Transparent.

2003-04-04  Jonathan Coles   <[email protected]>
 
        * Thuban/Model/classification.py: Fix assert calls.
        (ClassGroupProperties.SetLineColor, ClassGroupProperties.SetFill):
        Copy the color parameter rather than hold onto a reference.

        * Thuban/Model/color.py (Color.__copy__, Color.__deepcopy): Copy
        the color object.
        (NoColor.__copy__, NoColor.__deepcopy): Return 'self' so that we
        are sure there exists only one refernce to Color.None in the system.
        This allows us to use 'is' rather than the comparision functions.
        
        * Thuban/Model/save.py: Fix assert calls.
        
        * Thuban/UI/classifier.py: Fix assert calls.
        (ClassGrid._OnCellDClick): Call up to the classifier to open the 
        dialog to edit the groups properties.
        (ClassGrid._OnCellResize): Make sure that the scollbars are drawn
        correctly if a cell is resized.
        (ClassTable.SetClassification): New. Changes the classification
        that is in the table.
        (ClassTable.__SetRow): Allow groups to be prepended.
        (Classifier): New code for opening the EditProperties and 
        GenerateRanges dialogs.
        (SelectPropertiesDialog.__GetColor): Only set the color in the
        color dialog if the current color is not None.
        
        * Thuban/UI/dock.py: Fix assert calls.
        
        * Thuban/UI/legend.py: Fix assert calls.
        
        * Thuban/UI/renderer.py: Fix assert calls.
        
        * Thuban/UI/classgen.py (ClassGenDialog): Dialog for generating
        classifications.
        (GenRangePanel): Panel specific to range generation.
        (GenSingletonPanel): Panel specific to singleton generation.
        (ClassGenerator): Class responsible for actually generating
        the classification from the data gathered in the dialog box.
        (PropertyRamp): Generates properties whose values range from
        a starting property to an ending property.

2003-04-03  Bernhard Herzog  <[email protected]>

        * test/support.py (print_garbage_information): New function that
        prints information about still connected messages and memory
        leaks.
        (run_suite): Removed.
        (run_tests): New function for use as a replacement of
        unittest.main in the test_* files. This one calls
        print_garbage_information at the end.

        * test/runtests.py (main): Use support.print_garbage_information

        * test/test_layer.py: Use support.run_tests instead of
        unittest.main so we get memory leak information
        (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
        (TestLayer.test_point_layer, TestLayer.test_empty_layer)
        (TestLayerLegend.test_visibility): Call the layer's Destroy method
        to fix a memory leak.

        * test/test_classification.py: Use support.run_tests instead of
        unittest.main so we get memory leak information
        (TestClassification.test_classification): Call the layer's Destroy
        method to fix a memory leak.

2003-04-02  Bernhard Herzog  <[email protected]>

        * extensions/thuban/wxproj.cpp (check_version, check_version_gtk):
        Handle the reference counts of the return value and errors in
        PyArg_ParseTuple correctly.

        * Thuban/UI/application.py (ThubanApplication.OpenSession): Make
        sure the filename is absolute to avoid problems when saving the
        session again

        * Thuban/Model/table.py: Remove unnecessary import. Fix a typo.

2003-04-01  Jonathan Coles   <[email protected]>

        *  Thuban/UI/renderer.py (MapRenderer.draw_point_shape): Check
        that there actually are points in the returned list of points
        before trying to index into the list. The list may be empty if
        the shape is a Null Shape.

2003-04-01  Bernhard Herzog  <[email protected]>

        * test/test_map.py: Don't use from <module> import *

        (ClassDataPreviewer.Draw): Draw rectangles for polygon layers per
        RTbug #1769.

        * Thuban/UI/dock.py (DockableWindow.UnDock): Restore size and 
        position (although position doesn't work yet under GTK).
        (DockableWindow.Destroy): New. Called when the window must be
        closed. Namely needed when the DockFrame closes and must close
        its children.
        (DockFrame): Listen for EVT_CLOSE and destroy all children.

        * Thuban/UI/legend.py (LegendPanel.Destroy): New. Cleans up
        when then window is told to close.
        (LegendTree._OnMsgLayerChanged): Fixes a seg fault bug. See
        comment in source for more info.

        * Thuban/UI/main.py: Show the legend by default when Thuban starts.

        * Thuban/UI/mainwindow.py: Renamed OnClose to _OnClose for
        symmetry with other such methods.
        (MainWindow.ShowLegend): Show the legend docked by default.

2003-03-28  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py: Support for highlighting a specific
        group within the grid when the classification dialog is opened. 
        Also contains a lot of debugging printouts which will later
        be removed.

        * Thuban/UI/dock.py: Complete rework on the dock code so that
        that it is fairly removed from the rest of the Thuban application.
        It is easy to add new docks which the rest of the program having
        to be aware of them.

        * Thuban/UI/legend.py: Modifications to support selecting a 
        specific group in the classification dialog. Changed how layers
        are drawn when the layer is visible/invisible.

        * Thuban/UI/mainwindow.py: Removed legend specific code and
        replaced it with calls to the new dock code.

        * Thuban/UI/renderer.py (MapRenderer.__init__): Added assert
        to check if scale > 0. Trying to track down a divide by zero.

        This putback contains the code for dockable windows. There is
        no support in wxWindows as of this date for windows that can
        attach themselves to other windows. 

        The current model contains a DockableWindow which has a parent 
        window for when it is detached and a dock window that it puts 
        its contents in when it is docked. The contents of a DockableWindow 
        must be a DockPanel. DockPanel itself derives from wxPanel.

        * Thuban/Model/layer.py (Layer.ClassChanged): Send a LAYER_CHANGED
        message, not a LAYER_LEGEND_CHANGED message.

        * Thuban/Model/map.py (Map): Forward LAYER_CHANGED messages.

        * Thuban/UI/classifier.py (Classifier.__init__): Use wxADJUST_MINSIZE
        as one of the style properties for the fieldTypeText item to
        be sure that its size is correct when the text changes.

        * Thuban/UI/dock.py: New. Classes for the DockPanel and
        DockableWindow.

        * Thuban/UI/legend.py: Added some more buttons and made the
        LegendPanel a DockPanel.

        * Thuban/UI/mainwindow.py: Added sash windows to the main window
        and supporting functions for manipulating the sashes.
        (MainWindow.ShowLegend): Create a DockableWindow with the 
        LegendPanel as the contents.

        * Thuban/UI/messages.py: Added DOCKABLE_* messages

        * Thuban/UI/view.py (MapCanves.SetMap): Listen for LAYER_CHANGED,
        not LAYER_LEGEND_CHANGED, messages.

2003-03-25  Jonathan Coles   <[email protected]>

        * setup.py: Added custom script bdist_rpm_build_script so that
        when the rpm is built the path to wx-config is correct.

        * setup.cfg: Added line saying to use the custom build script

2003-03-20  Jonathan Coles   <[email protected]>

        Initial implementation of the Legend. 

        * Thuban/UI/legend.py: New. Creates a window that shows the map's
        Legend information and allows the user to add/modify classifications
        and how the layers are drawn on the map.

        * setup.py: New command 'build_docs' which currently uses
        happydoc to generate html documentation for Thuban.

        * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
        Returns a string which is appropriately describes the group.

        * Thuban/Model/layer.py (Layer.SetClassification): Generate a
        LAYER_CHANGED event instead of a LAYER_LEGEND_CHANGED event.

        * Thuban/Model/map.py (Map): Rename messages and use new, more
        specific, messages.

        * Thuban/Model/messages.py: New message to indicate that a layer's
        data has changed (LAYER_CHANGED). New map messages to indicate
        when layers have been added/removed/changed or if the stacking order
        of the layers has changed.

        * Thuban/Model/session.py: Rename and use new messages.

        * Thuban/UI/classifier.py: Remember if any changes have actually
        been applied so that if the dialog is cancelled without an application
        of changes we don't have to set a new classification.
        (ClassDataPreviewer): Pulled out the window specific code and put it
        ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
        symbols on any DC.
        
        * Thuban/UI/mainwindow.py: New code to open the legend.

        * Thuban/UI/view.py: Use new message names.

2003-03-19  Jonathan Coles   <[email protected]>

        * Thuban/UI/main.py (verify_versions): New. Checks the versions
        of Python, wxPython, and some other libraries.

        * extensions/thuban/wxproj.cpp (check_version): Checks the given
        version against what wxproj was compiled with.
        (check_version_gtk): If wxproj was compiled with gtk then check
        the given version against the version of the gtk library 
        currently being used.

2003-03-14  Bernhard Herzog  <[email protected]>

        * test/test_command.py: Run the tests when the module is run as a
        script

2003-03-14  Bernhard Herzog  <[email protected]>

        Implement selection of multiple selected shapes in the same layer:

        - Introduce a new class to hold the selection. This basically
          replaces the interactor which was nothing more than the
          selection anyway. A major difference is of course that the new
          selection class supports multiple selected shapes in one layer
        
        - Move the object that represents the selection from the
          application to the canvas. The canvas is a better place than the
          application because the selection represents which shapes and
          layer of the map displayed by the canvas are selected and
          affects how the map is drawn.

        - Make the selection and its messages publicly available through
          the mainwindow.

        - The non-modal dialogs do not get a reference to the interactor
          anymore as they can simply refer to their parent, the
          mainwindow, for the what the interactor had to offer.

        * Thuban/UI/selection.py: New module with a class to represent the
        selection.

        * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
        these unused messages

        * Thuban/UI/application.py (ThubanApplication.OnInit)
        (ThubanApplication.OnExit, ThubanApplication.SetSession): The
        interactor is gone now.
        (ThubanApplication.CreateMainWindow): There is no interactor
        anymore so we pass None as the interactor argument for now for
        compatibility.

        * Thuban/UI/view.py (MapCanvas.delegated_messages)
        (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
        Unsubscribe, delegate messages according to the delegated_messages
        class variable.
        (MapCanvas.__getattr__, MapCanvas.delegated_methods): Get some
        attributes from instance variables as described with the
        delegated_methods class variable.
        (MapCanvas.__init__): New instance variable selection holding the
        current selection
        (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
        pass them on to the renderer
        (MapCanvas.SetMap): Clear the selection when a different map is
        selected.
        (MapCanvas.shape_selected): Simple force a complete redraw. The
        selection class now takes care of only issueing SHAPES_SELECTED
        messages when the set of selected shapes actually does change.
        (MapCanvas.SelectShapeAt): The selection is now managed in
        self.selection

        * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
        (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
        Unsubscribe, delegate messages according to the delegated_messages
        class variable.
        (MainWindow.delegated_methods, MainWindow.__getattr__): Get some
        attributes from instance variables as described with the
        delegated_methods class variable.
        (MainWindow.__init__): The interactor as ivar is gone. The
        parameter is still there for compatibility. The selection messages
        now come from the canvas.
        (MainWindow.current_layer, MainWindow.has_selected_layer):
        Delegate to the the canvas.
        (MainWindow.LayerShowTable, MainWindow.Classify)
        (MainWindow.identify_view_on_demand): The dialogs don't need the
        interactor parameter anymore.

        * Thuban/UI/tableview.py (TableFrame.__init__)
        (LayerTableFrame.__init__, LayerTableFrame.OnClose)
        (LayerTableFrame.row_selected): The interactor is gone. It's job
        from the dialog's point of view is now done by the mainwindow,
        i.e. the parent. Subscribe to SHAPES_SELECTED instead
        of SELECTED_SHAPE
        
        * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
        is gone. It's job from the dialog's point of view is now done by
        the mainwindow, i.e. the parent.
        
        * Thuban/UI/classifier.py (Classifier.__init__): The interactor is
        gone. It's job from the dialog's point of view is now done by the
        mainwindow, i.e. the parent.

        * Thuban/UI/tree.py (SessionTreeView.__init__): The interactor is
        gone. It's job from the dialog's point of view is now done by the
        mainwindow, i.e. the parent.
        (SessionTreeCtrl.__init__): New parameter mainwindow which is
        stored as self.mainwindow. The mainwindow is need so that the tree
        can still subscribe to the selection messages.
        (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
        (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
        selection is now accessible through the mainwindow. Subscribe to
        SHAPES_SELECTED instead of SELECTED_SHAPE

        * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
        SHAPES_SELECTED message now.
        (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
        so deal with multiple shapes
        (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
        gone. It's job from the dialog's point of view is now done by the
        mainwindow, i.e. the parent.

        * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
        parameter is now a list of shape ids.
        (RecordTable.SetTable): The second parameter is now a list of
        indices.

        * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the
        selected_shape parameter and ivar to selected_shapes. It's now a
        list of shape ids.
        (MapRenderer.draw_label_layer): Deal with multiple selected
        shapes. Rearrange the code a bit so that the setup and shape type
        distinctions are only executed once.

        * test/test_selection.py: Test cases for the selection class

2003-03-11  Jonathan Coles   <[email protected]>

        * Thuban/Model/load.py: Temporary fix so that the xml reader
        doesn't cause Thuban to crash.

        * Thuban/Model/layer.py: Handle the cyclic references between
        a layer and its classification better, and be sure to disconnect
        the classification from the layer when the layer is destroyed
        so that we don't maintain a cyclic reference that may not be
        garbage collected.

        * Thuban/Model/classification.py: See comment for layer.py.

2003-03-12  Jan-Oliver Wagner <[email protected]>

        * HOWTO-Release: New. Information on the steps for releasing
        a new version of Thuban.

2003-03-11  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py: Add normal border to SelectPropertiesDialog.
        Use True instead of true.
        (Classifier): Should have a single panel in which all the controls lie.

        * Thuban/UI/proj4dialog.py: Add normal border.

        * Thuban/UI/tree.py: Fixed problem with bad item images under Windows.

        * Thuban/UI/mainwindow.py: Use True instead of true.

        * setup.py: Update some definitions to use wxWindows2.4 files

        * Data/iceland_sample_class.thuban: Fixed file so that the
        field_type information is present.

2003-03-10  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py (Classifier.__init__): Make the
        field type label grow so that when the text changes the
        size is updated correctly. This may be a wxWindows bug.

2003-03-10  Jonathan Coles   <[email protected]>

        * Thuban/UI/application.py: Changed SESSION_CHANGED to
        SESSION_REPLACED.

        * Thuban/UI/classifier.py: Wrap text with _(). 
        (ClassGrid.CreateTable): Set dimensions and size hints here,
        instead of in Reset, so we only set the size once.

        * Thuban/UI/dialogs.py: Don't need Shutdown(); just use Close()!

        * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
        Call Close() instead of Shutdown().

        * Thuban/UI/messages.py: Changed SESSION_CHANGED to SESSION_REPLACED.

        * Thuban/UI/tree.py: Changed SESSION_CHANGED to SESSION_REPLACED.
        Go back to using OnClose() instead of Shutdown().

2003-03-10  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py (Classifier): SelectField() needed
        to know the old field index as well as the new one.

2003-03-10  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py (Classifier): Use __SelectField()
        to correctly set the table information and call this from
        __init__ and from _OnFieldSelect so that all the information
        is up to date when the dialog opens and when a field is changed.

2003-03-10  Jonathan Coles   <[email protected]>

        * Thuban/Model/classification.py (Classification): Don't use
        layer's message function directly, use the ClassChanged() method
        when then classification changes. SetField/SetFieldType/SetLayer
        must keep the information about field name and field type in
        sync when an owning layer is set or removed.

        * Thuban/Model/layer.py: Added ClassChanged() so that the 
        classification can tell the layer when its data has changed.
        (Layer.SetClassification): Accepts None as an arguement to 
        remove the current classification and correctly handles
        adding a new classification.

        * Thuban/Model/load.py: Comment out print statement

        * test/test_classification.py, test/test_save.py: New and
        improved tests.

2003-03-07  Jonathan Coles   <[email protected]>

        * Thuban/Model/classification.py: Implemented __copy__ and
        __deepcopy__ for ClassGroup* and ClassGroupProperites so
        they can easily be copied by the classifier dialog.
        (ClassGroupProperites.__init__): The default line color should
        have been Color.Black.

        * Thuban/UI/classifier.py: Setting and Getting table values now
        uses a consistent set of functions.
        (Classifier): Now non-modal. Has field type label which changes
        as the field changes. Keep track of buttons in a list so that
        we can enable/disable the buttons when the None field is selected.
        (SelectPropertiesDialog): Add buttons to make the colors transparent.

        * Thuban/UI/dialogs.py (NonModalDialog.Shutdown): New method which
        does what OnClose did, but can be called by the application to
        close a window. Needed when a session changes, and we have to
        close the classifier windows.

        * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
        Shuts down open dialogs. Used when a new session is created
        or a session is opened.
        (MainWindow.SaveSession): Should only call application.SaveSession()
        if we don't call SaveSessionAs first.
        (MainWindow.Classify): Allow different classifier dialogs for
        different layers.

        * Thuban/UI/tree.py (SessionTreeView): Remove OnClose and let
        the parent class handle it. Add Shutdown() to unsubscibe from
        event notification and call the parent Shutdown(). This was
        necessary so the application can close the tree window.

2003-03-06  Jonathan Coles   <[email protected]>

        * Thuban/Model/classification.py: Minor documentation changes,
        Addition of __eq__ and __ne__ methods.
        (Classification.SetLayer): prevent recursion between this method
        and Layer.SetClassification().

        * Thuban/Model/color.py: Addition of __eq__ and __ne__ methods.

        * Thuban/Model/layer.py (SetClassification): prevent recursion 
        between this method and Classification.SetLayer().

        * test/test_classification.py, test/test_load.py,
        test/test_session.py: Fixed and added tests for the classification
        classes.

2003-03-06  Bernhard Herzog  <[email protected]>

        * Thuban/UI/classifier.py (ClassGrid.__init__)
        (ClassGrid.CreateTable): Move the SetSelectionMode call to
        CreateTable because otherwise it triggers an assertion in
        wxPython/wxGTK 2.4.

2003-03-05  Jonathan Coles   <[email protected]>

        * Thuban/common.py: Move FIELDTYPE constants back to table.py.

        * Thuban/UI/classifier.py: import FIELDTYPE constants from table.

        * Thuban/Model/table.py: Put FIELDTYPE constants back.

2003-03-05  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py: Added class documentation.
        Fixed RTbug #1713, #1714. Added Move[Up|Down] buttons.
        Store just the groups in the table and generate the other
        column information when it is requested. Add "None" field
        to pull-down to select no classification.

        * Thuban/common.py: Moved FIELDTYPE constants from table.py 
        (Str2Num): Only catch ValueError exceptions.

        * Thuban/Model/classification.py: Class documentation. Renaming
        of methods with Stroke to Line. Groups are stored in a single
        list with the default as the first element. Groups are searched
        in the order they appear in the list.

        * Thuban/Model/color.py: Documentation.

        * Thuban/Model/layer.py (Layer): Add GetFieldType to retreive
        the kind of data represented by a field.

        * Thuban/Model/load.py (ProcessSession): Use proper string
        conversion function; fixes RTbug #1713.

        * Thuban/Model/save.py (Saver): Store field type information.

        * Thuban/Model/table.py: Put FIELDTYPE constants in common.py.
        (Table): Add field_info_by_name() to retrieve field information
        by specifying the field name, not the number.

        * Thuban/UI/mainwindow.py: Function name changes.

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
        get the layer classification once. Don't try to classify 
        values when the field is None: just use the default properties.

        * Thuban/UI/view.py: Function name changes.

        * Doc/thuban.dtd: Add field_type attribute to a classification.

2003-03-04  Bernhard Herzog  <[email protected]>

        * Doc/thuban.dtd: Use correct syntax for optional attributes. Make
        the fill and stroke layer attributes optional with suitable
        default values. Add the stroke_width layer attribute. Use correct
        syntax for empty elements. Make the attribute list for labels
        refer to the label element.

2003-03-04  Bernhard Herzog  <[email protected]>

        * setup.py (thuban_build_py.build): Add a comment about distutils in
        Python 2.3 containing some of the functionality we implement in
        setup.py ourselves.

        * Thuban/UI/classifier.py (ClassGrid.__init__): Set the table
        before the selection mode. Doing it the other way round triggers
        an assertion in wxWindows.

        * Thuban/Model/save.py (escape): Fix typo in doc-string

        * Thuban/Model/classification.py: Remove unnecessary wxPython
        import

2003-03-04  Jonathan Coles   <[email protected]>

        * Thuban/Model/classification.py (ClassGroupRange.GetProperties):
        Parameter 'value' should default to None.

        * Thuban/UI/mainwindow.py: Use Layer.GetClassification() since
        the class attribute __classification is now private.

        * Thuban/UI/classifier.py (ClassGrid): Moved OnCellDClick() from
        Classifier to ClassGrid. Added support for removing selected rows,
        which including code for keeping track of when cells are selected,
        and deselected.
        (ClassTable): Support for added/removing rows. Fixed a problem
        with __ParseInput whereby it would not allow strings (only numbers)
        to be entered.
        (Classifier): Added button and supporting code for removing
        selected rows.

2003-02-27  Jonathan Coles   <[email protected]>

        * Thuban/common.py: Moved color conversion functions into
        Thuban/UI/common.py.
        (Str2Num): Now converts the float (not the string) to a long/int
        so that an exception isn't thrown.

        * Thuban/UI/common.py: Common functions used in several UI modules

        * Thuban/Model/classification.py: Changed the class hierarchy
        so that a Classification consists of Groups which return

        functions from Thuban color objects to wxWindow colour objects.

        * Thuban/Model/classification.py (Classification): Renamed
        GetProperties() to GetClassData(). Used the new iterator
        in TreeInfo().

        Colors in the tree view.

        * Thuban/Model/layer.py (Layer.TreeInfo): Added a call to build
        the tree info for classifications. Commented out unnecessary lines.

        * Thuban/Model/classification.py (Classification.TreeInfo): New
        function to add information about the classification into the
        tree view.

        (FloatComparisonMixin.assertFloatSeqEqual): give a more useful
        message if the assertion fails and don't return the return value
        of self.assert_. In assertFloatSeqEqual the return meant that not
        all items of the sequence were compared.

2002-09-20  Bernhard Herzog  <[email protected]>

        * test/test_fileutil.py: New. Test cases for Thuban.Lib.fileutil

        differences in the way %g is handled.

        * test/test_layer.py (TestLayer.test_empty_layer): Create an empty
        DBFfile too because Thuban layers can't yet cope missing DBF
        files.

2002-09-20  Bernhard Herzog  <[email protected]>

        * test/test_menu.py: Use initthuban instead of

        (MainWindow.set_position_text): Put the code that puts the text
        with the mouse position into the status bar into the new method
        set_position_text so that it can overwritten in derived classes.

        entries.
        (MainWindow.build_menu): remove an incorrect comment.

2002-09-10  Bernhard Herzog  <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.Map): New.
        (_tool_command): Add sensitive parameter

        brief instructions on how to run them

2002-08-29  Bernhard Herzog  <[email protected]>

        * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Handle
        arcs with multiple parts.

        * Thuban/UI/view.py (ZoomInTool.MouseUp, ZoomOutTool.MouseUp):
        Handle degenrate rectangles.

        * Thuban/Model/table.py: Make writing records work correctly:
        (Table.__init__): Keep track of whether the DBF is open for
        writing
        (Table.write_record): Open the DBF file for writing when necessary

2002-08-27  Bernhard Herzog  <[email protected]>

        * Thuban/Model/table.py (Table.write_record, Table.__init__): Open
        dbf files only for reading by default. Use a new writable dbf
        object for writing.

2002-08-26  Bernhard Herzog  <[email protected]>

        * Thuban/UI/mainwindow.py: Refactor the context creation:
        (MainWindow.Context): New method to return a context
        (MainWindow.invoke_command, MainWindow.update_command_ui): Use the
        new method

        * Thuban/UI/tableview.py (TableGrid, LayerTableGrid): Split the
        layer table specific code from TableGrid into LayerTableGrid
        (TableFrame, LayerTableFrame): Split the layer table specific code
        from TableFrame into LayerTableFrame
        (LayerTableGrid.select_shape): Remove a debug print

        * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Use the
        LayerTableFrame

2002-08-23  Bernhard Herzog  <[email protected]>

        * Thuban/Model/layer.py (Layer.__init__): Make sure we have an
        absolute filename.

2002-08-22  Bernhard Herzog  <[email protected]>

        * Thuban/Model/table.py (Table.write_record): New method to write
        records.
        (Table.__init__): Open the DBF file for writing too.

        * Thuban/UI/controls.py (RecordTable.SetValue): Write the value
        into the underlying table.

        extensions/shapelib/dbfopen.c (DBFCommit): New API function to
        commit any changes made to the DBF file.

        * Thuban/UI/mainwindow.py (make_check_current_tool)
        (_tool_command): Put the code that generates the "checked"
        callback into a separate function so that we can reuse it
        elsewhere

        * Thuban/Model/save.py (Saver): New class to handle serializing a
        session into an XML file. The main reason to introduce a class is
        that applications built on Thuban can derive from it so that they
        can save additional information in a session file.
        (save_session): Delegate almost all the work to the Saver class.
        Rename the filename argument to file because it may be a file like
        object now.

        * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
        code. Remove the little test code which would be executed when the
        module is run as a script which didn't work anymore since it can't
        import the other Thuban modules.
        (ProcessSession, load_session): Refactor the ProcessSession to
        have one method for each element start and end tag so that derived
        classes can easily override the processing of individual tags.
        Also, always parse with namespaces enabled because applications
        built on top of Thuban will likely use namespaces if they extend
        the session file format.

        extensions/shapelib/dbfopen.c: Update to the versions of shapelib
        1.2.9

        * setup.py (Lib.wxproj extension): Don't link shpopen.c and put
        the pyshapelib directoy into the list of include dirs, so that
        pyshapelib_api.h can be found.

        * extensions/thuban/wxproj.cpp (pyshapelib_api): New variable that
        holds the pyshapelib C-API
        (draw_polygon_shape, point_in_polygon_shape, shape_centroid): Use

        menu

2002-02-15  Bernhard Herzog  <[email protected]>

        * Thuban/Model/layer.py (Layer.Shape): list append only takes one
        argument (python <= 1.5.2 erroneously accepted multiuple
        arguments)

2002-02-04  Bernhard Herzog  <[email protected]>

        * Thuban/UI/identifyview.py (IdentifyGridCtrl): New class to use a
        RecordGrid in the identifyview.
        (IdentifyView.__init__): Use IdentifyGridCtrl instead of

        * Thuban/UI/controls.py (RecordTable, RecordGridCtrl): New classes
        implementing a grid for a single row of a thuban table.

        * Thuban/UI/view.py (MapCanvas.SelectShapeAt): Search through all
        layers by default. Easier to use than the previous default of only
        searching through the select layer which meant that if no layer
        was selected, you couldn't select a shape.

        * Thuban/UI/tableview.py (TableGrid.__init__): Fix typo

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Honour the

        * extensions/thuban/wxproj.cpp (project_points): Fix two
        off-by-one errors in the last loop that joins the various parts
        together.

2002-01-14  Bernhard Herzog  <[email protected]>

        * setup.py (data_dist.make_distribution): Fix some typos

2001-09-18  Bernhard Herzog  <[email protected]>

        (data_dist): New command class for data distribution

2001-09-14  Bernhard Herzog  <[email protected]>

        * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape):
        Handle the case of no layer (i.e. layer is None) properly.

        * Thuban/UI/proj4dialog.py (UTMDialog.__init__, Proj4Dialog.__init__):
        Set the initial selection of the combo boxes to reflect the
        projection we're starting with in a way that works on windows,
        too.

        * Thuban/Lib/connector.py (Connector.print_connections): Print the
        puiblisher's ids in hex to make it easier to compare them to the
        standard repr of python methods

        * Thuban/Model/map.py (Map.Destroy): Unsubscribe the label_layer
        messages

2001-09-13  Bernhard Herzog  <[email protected]>

        * Thuban/UI/tree.py (SessionTreeCtrl.OnSelChanged): Make sure to
        deselect the layer if no layer is selected

        * Thuban/UI/view.py (MapCanvas.OnPaint): Only delay drawing to
        idle time when there actually is something to draw. If there's
        nothing to draw simply clear the window
        (MapCanvas.do_redraw): Call dc.EndDrawing and add some comments.
        (MapCanvas.SetMap): force a redraw in all cases because
        FitMapToWindow doesn't always do it.
        (MapCanvas.ZoomFactor): Add an optional parameter, center, to
        specify the point to move into the center of the window
        (ZoomOutTool.MouseUp, ZoomInTool.MouseUp): If the mouse wasn't
        dragged, zoon in/out by a factor of 2
        (MapCanvas.find_shape_at): Iterate backwards (i.e. with decreasing
        index, i.e. reversed drawing order) so that objects appearing to
        be in from of others are selected first. This is probably mostly
        relevant for point shapes where the symbols used may overlap

        * Thuban/Model/session.py (create_empty_session): Unset the
        modified bit before returning it

        * Thuban/UI/mainwindow.py (MainWindow.NewSession): Use

        * Thuban/UI/mainwindow.py (MainWindow.__init__): Set the size of
        the tool bitmaps.
        (MainWindow.OnClose, MainWindow.save_modified_session): Separate
        the code that asks whether the session should be saved into the
        new method save_modified_session.
        (MainWindow.OpenSession, MainWindow.NewSession): Use the new
        method to save modified session here too.

2001-09-11  Bernhard Herzog  <[email protected]>

        * setup.py (InnoIconItem): fix typo

        (thuban_bdist_inno.run):
        (bdist_inno.run): Move the decision not to create symlinks on
        non-nt platforms to thuban_bdist_inno and do it unconditinally
        since we never want to create the symlinks here

2001-09-10  Bernhard Herzog  <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.IdentifyTool): Popup the
        identify view immediately

        * Thuban/UI/controls.py: New file with two classes RecordListCtrl
        and SelectableRecordListCtrl that implement the code shared by the
        identify view and the label dialog

        * Thuban/UI/identifyview.py (IdentifyListCtrl): Derive from the
        new class RecordListCtrl

        * Thuban/UI/labeldialog.py (LabelDialog.OnOK): Check whether the
        return value of GetValue is None instead of using it as a boolean
        directly so that Zero numbers are handled properly.
        (LabelListCtrl): Derive from the new class
        SelectableRecordListCtrl

        * Thuban/UI/proj4dialog.py (Proj4Dialog.__init__):
        (Proj4Dialog.dialogLayout): Make the window resizable and set the
        size of the text control explicitly to make the sizers work on
        both Windows and X.

2001-09-07  Bernhard Herzog  <[email protected]>

        * Thuban/UI/view.py (MapCanvas.find_shape_at):Add a new parameter
        that can limit the search to the currently selected layer.
        (MapCanvas.SelectShapeAt): Make sure that the currently selected
        layer stays selected even when no shape is found
        (MapCanvas.FitRectToWindow): If the rect has zero with or zero
        height do nothing (avoids zero division errors)

2001-09-06  Bernhard Herzog  <[email protected]>

        * Thuban/UI/tree.py (SessionTreeCtrl, SessionTreeView.__init__):
        Correct the spelling of SessionTreeCtrl. dabbrev is too damn
        convenient :-)
        (SessionTreeCtrl.__init__, SessionTreeCtrl.update_tree): Introduce
        a new instvar layer_to_item to map layers to tree items
        (SessionTreeCtrl.layer_selected): Select the appropriate tree item
        to match the current selection in the interactor

        * Thuban/UI/interactor.py (Interactor.SelectedLayer):
        (Interactor.HasSelectedLayer): New methods to query the current
        selection

        * Thuban/UI/mainwindow.py (MainWindow.current_layer):
        (MainWindow.has_selected_layer): Simply call the appropriate
        interactor method

        * Thuban/UI/mainwindow.py (MainWindow.__init__):
        (MainWindow.LayerShowTable):
        (MainWindow.identify_view_on_demand): Store the interactor in an
        instvar and use that reference instead of going through main.app

        * Thuban/UI/mainwindow.py (MainWindow.ShowSessionTree):
        * Thuban/UI/application.py (ThubanApplication.OnInit):
        * Thuban/UI/main.py (main): Create the session tree view in main
        with the new mainwindow method ShowSessionTree and not directly
        the application's OnInit method

        * Thuban/UI/tree.py (myTreeCtrlPanel):
        (SessioinTreeCtrl): Rename to SessioinTreeCtrl and turn it into a
        TreeCtrl isntead of a panel. This affects most method since we now
        refer to self instead of self.tree
        (SessionTreeView): New class implementing a non-modal dialog
        showing the session tree.

        * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Pass the

        (TableGrid.OnRangeSelect):
        (TableGrid.OnSelectCell):
        (TableFrame.__init__):
        (TableFrame.row_selected):
        Selecting rows in the grid view now updates the selected shapes
        through the TableFrame. To achieve this we derive TableGrid from
        Publisher and introduce the message type ROW_SELECTED which the
        TableFrame subscribes to and which is issued by OnRangeSelect and
        OnSelectCell

        (DataTable.SelectRow): Removed because it's no longer needed in
        the row/shape selection scheme

        * Thuban/UI/dialogs.py: New file implementing common classes for
        dialogs

        * Thuban/UI/tableview.py (TableGrid.__init__): Don't subscribe to

        parent.
        (TableGrid.select_shape): Only update the selection if the shape
        is not None.
        (TableFrame): Inherit from the new NonModalDialog class.
        (TableFrame.__init__, TableFrame.select_shape): Handle the
        SELECT_SHAPE message.

        of opened non-modal dialogs.

        (MainWindow.__init__): Initialize the new non-modal dictionary
        management code
        (MainWindow.LayerShowTable): maintain separate dialogs for each
        table using the non-modal dialog management code to only open a
        view once for each table.

        (MainWindow.IdentifyTool):
        (MainWindow.__init__):
        (MainWindow.identify_view_on_demand): Don't open the identify view
        in IdentifyTool anymore. This will be done automatically by the
        new method identify_view_on_demand which handles the
        SELECTED_SHAPE message so that the identify view will be opened on
        demand

        * Thuban/UI/identifyview.py (IdentifyListCtrl.__init__): Remove
        the interactor argument. The SELECTED_SHAPE message is now handled
        by the parent.
        (IdentifyView.__init__): Add the interactor argument so that we
        can handle the SELECTED_SHAPE message here
        (IdentifyView.selected_shape): New method to handle the
        SELECTED_SHAPE messages

        * Thuban/UI/identifyview.py (IdentifyView): Derive from the new
        NonModalDialog class
        (IdentifyView.OnClose): Extend the inherited version to
        unsubscribe SELECT_SHAPE

        * Thuban/Model/session.py (Session.UnsetModified): Remove debug prints

2001-09-05  Bernhard Herzog  <[email protected]>

        * Thuban/UI/view.py (MapCanvas.__init__): New argument, interactor.

        * Thuban/UI/mainwindow.py (MainWindow.__init__): New argument
        interactor to pass through to the MapCanvas

        * Thuban/UI/application.py (ThubanApplication.OnInit): Use the new
        argument to the MainWindow constructor to get rid of the ugly hack
        that made main.app available early just so that the mapcanvas
        could access the interactor object.

2001-09-04  Bernhard Herzog  <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.RunMessageBox): New method
        that runs a modal message box
        (MainWindow.OnClose): Use the new method
        (MainWindow.RemoveLayer): Just do nothing in case no layer is
        selected. The command should be grayed out anyway, so there's no
        need to pop up a message box.
        (MainWindow.AddLayer): Pop up a message box with an error message
        if the shape file can't be opened

        * Thuban/Model/layer.py (Layer.__init__): Open the shapefile
        immediately. This will cause an exception in case the file can't
        be opened and we can display an appropriate message.

        * MANIFEST.in: Add extensions/pyprojection/LICENSE

        * setup.py (thuban_bdist_rpm): New class implementing a Thuban
        specific bdist_rpm command.

        * Thuban/UI/main.py: Catch ImportError exceptions when importing
        the locale module because it may not be available on some
        installations.

        * extensions/pyprojection/LICENSE: Copy of the license text in
        Projection.i. Having it in a separate file makes it easier to
        refer to license text in e.g. RPMs

2001-09-03  Bernhard Herzog  <[email protected]>

        * setup.py: use wx-config instead of wxgtk-config because it's
        more generic

        * setup.py (ThubanInstall.get_outputs): Add the symlink in
        <prefix>/bin to the outputs
        (ThubanInstall.link_file): New method to link files. We need this
        because the standard copy_files refuses to link non-existing
        files.
        (ThubanInstall.run): Remove the leading install root from the
        script filename if an install root was specified and use the new
        link_file method

        when linking thuban.py to <prefix>/bin

2001-08-31  Bernhard Herzog  <[email protected]>

        * setup.py: In the setup call, the install parameters shouldn't
        have trailing slashes because distutils on non-posix platforms
        doesn't like that. The same applies to other directories like
        "Resources/Bitmaps"

        In the configuration section for nt, move the wxWindows directory
        optins into the part clearly marked as editable.

        (InstallLocal.initialize_options):
        (InstallLocal.user_options): remove the currently unused debug
        flag
        (thuban_build_py.find_all_modules): Add this method so that it
        works for our case of having packages and modules in one
        distribution as well.
        (ThubanInstall.initialize_options):
        (ThubanInstall.finalize_options):
        (ThubanInstall.user_options):
        (ThubanInstall.boolean_options): Add new options, do-symlink and
        extra files. Since these are the first ThubanInstall specific
        options, override user_options and boolean_options
        (ThubanInstall.run): Honor the new do-symlink and extra-files
        options.
        (ThubanInstall.get_outputs): Add to override the base-class's
        version and add the extra-files to the outputs
        (bdist_inno): New class for windows distributions with Inno Setup
        (InnoIconItem): Helper class for bdist_inno
        (thuban_bdist_inno): Thuban specific version of bdist_inno. Added
        this together with the appropriate parameters, to the setup call.

        * setup.cfg (bdist_inno): added new section for the inno setup
        installer

        * Thuban/UI/tree.py (myTreeCtrlPanel.__init__): New inst var
        changing_selection to avoid recursive selection events when
        modifying the selection in response to a selection event.
        (myTreeCtrlPanel.normalize_selection): Set the new inst var when
        changing the tree's selection.
        (myTreeCtrlPanel.OnSelChanged): Only normalize the selection when
        we're not being called indirectly from normalize_selection.

        * Thuban/UI/mainwindow.py (MainWindow.update_command_ui): Call
        event.Check only if the command is actuall checkable.
        (MainWindow.__init__): Call the toolbar's Realize method to make
        sure that the items are actually shown

2001-08-28  Bernhard Herzog  <[email protected]>
