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

        * test/test_save.py (SaxEventLister, sax_eventlist): Removed. Use
        the implementation in xmlsupport instead.
        (SaveSessionTest.compare_xml): sax_eventlist is now in xmlsupport

        * test/test_proj.py: Import sax_eventlist from xmlsupport instead
        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
        by the current thuban version.
        (ClassificationTest.TestLayers, TestSingleLayer.test)
        (TestLayerVisibility.test, TestClassification.test)
        (TestLabels.test, TestLayerProjection.test, TestRasterLayer.test):
        Add check_format() calls and fix the thuban data to match the data
        that would be written by saving the session loaded from it.

        * test/xmlsupport.py (SaxEventLister, sax_eventlist): Copies of
        the same class and function in test_save.

        * test/test_xmlsupport.py (TestEventList): New. test cases for
        sax_eventlist

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

        * Resources/XML/thuban.dtd: Add comment about which versions of
        Thuban are covered by this DTD
        (map): Fix content model for layers and raster layers. There can
        be any number or layers and raster layers in any order.

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

        * 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
        is None.

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.

        * test/test_load_0_2.py: New file with the load tests for thuban
        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/test_xmlsupport.py: New. Tests for the xmlsupport module

        * test/test_save.py (SaveSessionTest): Derive from ValidationTest
        so that we can validate the
        (SaveSessionTest.testEmptySession)
        (SaveSessionTest.testSingleLayer)
        (SaveSessionTest.testSingleLayer)
        (SaveSessionTest.testLayerProjection)
        (SaveSessionTest.testRasterLayer)
        (SaveSessionTest.testClassifiedLayer): Validate the generated XML

        * 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.

        * Thuban/Model/resource.py: Renamed functions to following the
        function_names_with_underscores style.
        (has_gdal_support): New function that returns true if the gdal 
        library is available. Addresses RTbug #1877.

        * Thuban/UI/application.py (ThubanApplication.OpenSession):
        Display a message box if the gdal library is not available, but
        only if there are any layers that would use it. Addresses RTbug #1877.

        * Thuban/UI/classgen.py: Use renamed projection resource functions.
        (GenUniformPanel.__CalcStepping): Fix a slight discrepency 
        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 
        optimize if a raster layer is visible. Fixes RTbug #1931.
        Only draw the raster layer if the gdal library is available.
        Addresses RTbug #1877.

        * test/test_classgen.py: Add tests for generate_singletons,
        generate_uniform_distribution, generate_quantiles. Fixes RTbug #1903.
        (test_calculate_quantiles): Fix some tests to catch the new
        ValueError that is raised.

        * test/test_proj.py: Use renamed projection resource functions.

        Do not cache the values returned by the tree widget's

        * Thuban/UI/classifier.py: Remove unused import of ClassGenerator.

        * 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.

        checks for a destination dataset. Add more clean up code.

        Typo fixed.

2003-05-22  Bernhard Herzog  <[email protected]>

        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.

        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.

        * 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

        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.

        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: New, version information for Thuban: Last
        modification date and last ChangeLog entry date.

        * Thuban/UI/mainwindow.py (MainWindow.About()): Extended version
        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.

        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.

        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

        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.

        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.

        * test/test_load.py: Add new test data contents_test_visible.
        (LoadSessionTest.setUp): save test data.
        (LoadSessionTest.testLayerVisibility): Test if the visible flag
        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
        instance variable store holding the datastore. For intermediate
        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.
        (Layer.Destroy): No need to explicitly destroy the shapefile or
        table anymore.

        session's OpenShapefile method to open shapefiles

        * test/test_classification.py
        (TestClassification.test_classification): Use the session's
        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.
        (TestMapWithContents.tearDown): Make sure that all references to
        layers, maps and sessions are removed otherwise we may get a
        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.

        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

        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.

2003-04-17  Bernhard Herzog  <[email protected]>

        * Thuban/Model/layer.py: Don't import LAYER_LEGEND_CHANGED.
        (Layer): Update doc-string since LAYER_LEGEND_CHANGED is not used
        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.

        general XML writing methods that were part of SessionSaver.
        (SessionSaver): Renamed from Saver.

        * test/test_proj.py: New test cases for the projection
        file read and write functions.

2003-04-16  Jonathan Coles   <[email protected]>

        * Thuban/Model/classification.py: Use repr() around values 
        in the ClassGroup*.__repr__() methods so it is clearer when
        a value is a string and when it is a number.

        * test/test_load.py: Rework the classification test to test
        that we can load old files. 
        (testLabels): Test a file where the groups have labels.

2003-04-16  Bernhard Herzog  <[email protected]>

        Safer implementation of the performance enhancements of the
        low-level renderer:
        
        * 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.

        * Thuban/UI/renderer.py (MapRenderer.polygon_render_param): New
        method to instantiat the low-level render parameter
        (MapRenderer.draw_shape_layer): Use the new method. Remove some
        commented out code.
        (MapRenderer.draw_polygon_shape): Make the first parameter not the
        layer but the low-level render parameter
        (ScreenRenderer.draw_shape_layer): Use the low-level render
        parameter.

        correctly.

2003-04-15  Jonathan Coles   <[email protected]>

        * 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.
        (draw_polygon_shape): Removed initialization code that is
        now in draw_polygon_init().

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Make
        drawing initialization call to draw_polygon_init()
        (MapRenderer.draw_polygon_shape): Use new signature of
        draw_polygon_shape.

        * Thuban/UI/classgen.py (GenUniformPanel): Fix spin control
        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.

        Refactored the code to change variable names.
        (LegendTree.__FillTreeLayer): Only list a group if it is visible.

        * Thuban/UI/mainwindow.py: MainWindow.OpenClassifier renamed to

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.

        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.

        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.

        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

        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

        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.

2002-08-21  Bernhard Herzog  <[email protected]>

        * setup.py (ThubanInstall.run): Don't repr install_lib_orig

        message if the stacking order actually has changed. Add

        * Thuban/UI/view.py: Keep the temporary bitmap used during drawing
        around to speed up most redraws:
        (MapCanvas.__init__): New instance variable bitmap which holds the
        bitmap
        (MapCanvas.do_redraw): Redraw self.bitmap if necessary. Use
        self.bitmap to draw.

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

        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

        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

        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

        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

        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

        the window when the first layer is added to the map.

        * setup.py (ThubanInstall.run): Honor the build root (self.root)
        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):
