2    
3            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
4            turning on the busy cursor to allow the system to change the
5            cursor before we begin painting. This fixes a problem that
6            was occuring only under GTK. Fixes RTbug #1840.

12    
13            * Thuban/Model/save.py (sort_data_stores): New. Make topological
14            sort of the data sources so they can be written with sources that

77            (SaveSessionTest.testLayerProjection): The filename used was the
78            same as for testSingleLayer. Use a different one.
79            (SaveSessionTest.test_dbf_table)

100            * test/test_layer.py (TestLayer.test_derived_store): Add
101            a test for the new exception in DerivedShapeStore.__init__.
102    
103            * test/support.py (FloatTestCase): Removed since there is
104            already FloatComparisonMixin. Fixes RTbug #1954.
105            (FloatComparisonMixin.assertFloatEqual): Include test for
106            infinity that was part of FloatTestCase.
107    
108            * test/test_range.py (RangeTest): Inherit from
109            support.FloatComparisonMixin now that we don't have
110            support.FloatTestCase.
111    
112    2003-06-20  Bernhard Herzog  <[email protected]>
113    
114            * test/test_save.py (SaxEventLister, sax_eventlist): Removed. Use

122    
123            * test/test_load.py (LoadSessionTest.check_format): New helper
124            method to make sure the test files we load might have been written
125            by the current thuban version.
126            (ClassificationTest.TestLayers, TestSingleLayer.test)
127            (TestLayerVisibility.test, TestClassification.test)
128            (TestLabels.test, TestLayerProjection.test, TestRasterLayer.test):
129            Add check_format() calls and fix the thuban data to match the data
130            that would be written by saving the session loaded from it.
131    
132            * test/xmlsupport.py (SaxEventLister, sax_eventlist): Copies of

140            * Resources/XML/thuban.dtd: Add comment about which versions of
141            Thuban are covered by this DTD
142            (map): Fix content model for layers and raster layers. There can
143            be any number or layers and raster layers in any order.
144    
145    2003-06-20  Jonathan Coles   <[email protected]>
146    
147            This is mainly about fixing RTbug #1949.
148    
149            * Thuban/Model/classification.py: Remove "from __future__"
150            import statement since python 2.2 is the earliest supported
151            version.
152    
153            * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
154            Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES
155            depending on the units this projection *forwards* into.
156    
157            * Thuban/Model/save.py (SessionSaver.write_classification):
158            Remove unnecessary use of lambdas and nested functions.
159    
160            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Do scale
161            adjustment here if the map projection uses degrees.
162    
163            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
164            scale adjust code since it is now done before calling
165            this method. Don't do anything if the map projection
166            is None.
167    
168    2003-06-19  Bernhard Herzog  <[email protected]>
169    
170            Move version specific load tests to their own file.
171    
172            * test/test_load.py: Expand the doc-string to explain a bit how to
173            handle file format changes.
174            (TestClassification.test): Update the docstring as this test is
175            not about Thuban 0.2 anymore.
176    
177            * test/test_load_0_2.py: New file with the load tests for thuban
178            files created with Thuban 0.2 and earlier.
179    
180    2003-06-19  Bernhard Herzog  <[email protected]>
181    
182            Add XML validation to some of the tests. Validation will only be
183            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
184            To make the DTD available to the test cases it's moved into
185            Resources/XML
186    
187            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
188            for versions up to and including 0.2. Two slight changes: added an
189            encoding specification and fixed the comment which refered to
190            GRASS, not Thuban
191    
192            * test/xmlsupport.py: New support module for tests involving XML.
193            Currently there's a mix-in class for XML validation.
194    
195            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
196    
197            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
198            so that we can validate the
199            (SaveSessionTest.testEmptySession)
200            (SaveSessionTest.testSingleLayer)
201            (SaveSessionTest.testSingleLayer)
202            (SaveSessionTest.testLayerProjection)
203            (SaveSessionTest.testRasterLayer)
204            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
205    
206            * test/runtests.py (main): Call print_additional_summary instead
207            of print_garbage_information
208    
209            * test/support.py (resource_dir): New function to return the
210            "Resource" subdirectory
211            (print_additional_summary): New function to combine several
212            summary functions
213            (run_tests): Use print_additional_summary instead of calling
214            print_garbage_information directly
215    
216    2003-06-19  Bernhard Herzog  <[email protected]>
217    
218            * Doc/thuban.dtd (classification): Correct the content model of
219            the classification element.
220            (projection): Add the "name" attribute
221    
222    2003-06-19  Frank Koormann   <[email protected]>
223    
224            MERGE from the greater-ms3 branch.
225    
226            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
227            scale if projection is latlong to get better estimate.
228    
229            Fix problem of hidden properties dialog under windows after double
230            click on layer tree:
231            The tree control always gets an Expanded / Collapsed event after
232            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
233            raises the already displayed window.
234    
235            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
236            raiseProperties initialized to prevent endless loops
237            (LegendTree._OnItemActivated): Depending on self.raiseProperties
238            simply raise the properties or open the dialog and issue a second
239            event.
240    
241    2003-06-18  Jonathan Coles   <[email protected]>
242    
243            * setup.py: Fix a few problems that occured under Windows.
244    
245    2003-06-18  Jonathan Coles   <[email protected]>
246    
247            When Thuban loaded the map was redrawn twice because the
248            legend was being opened after the mainwindow was created
249            and not during its creation. This meant the map was drawn
250            initially and then had to be redrawn when the legend
251            caused the display to change. Now the legend is opened
252            in the mainwindow constructor which resolves this issue.
253    
254            Also, although we were checking for the existence of
255            gdal and gdalwarp modules, the gdalwarp extension was
256            still being compiled (which may fail if the system doesn't
257            have gdal installed). the build_ext command to setup.py
258            now accepts the flags --with-gdal and --without-gdal.
259            If --without-gdal is specified setup.py will try to
260            use the gdal parameters specified by gdal-config. Under
261            windows, those parameters have to be set in setup.py
262            as with proj4 an wxWindows.
263    
264            * setup.py: Use a list instead of seperate variables for
265            extension parameters so we can create a generic function
266            that runs an appropriate *-config script.
267            (run_cs_script): Renamed from run_wx_script and modified
268            to accept a second argument which is a list of lists to
269            be filled in by the values returned from running the command.
270            (thuban_build_ext): New. Extends the build_ext command and
271            provides the options --with-gdal/--without-gdal which then
272            optionally includes the gdalwarp extension.
273    
274            * Thuban/Model/resource.py: First check if we can import
275            the gdalwarp Thuban extension before checking for gdal.
276            Also added some comments.
277            
278            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
279            the map is None which may be the case if none has been loaded
280            yet.
281    
282            * Thuban/UI/main.py (main): Remove call to ShowLegend.
283    
284            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
285    
286            * Thuban/UI/renderer.py: Check for gdal support before importing
287            gdalwarp.
288            (MapRenderer.render_map): Only try to optimize if we have gdal
289            support otherwise nothing will get drawn.
290    
291            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
292            during startup before a map has been created. Check if map is None
293            before using it and do nothing if it is.
294    
295    2003-06-17  Jonathan Coles   <[email protected]>
296    
297            Fix the problem with raster layers under Windows that caused
298            Thuban to crash. The view should respond to layer projection
299            changed events to update the display. Changes to a projection
300            should not cause the map to be set to full extent.
301            
302            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
303            current_map_proj to remember the current map projection so that
304            when the projection changes we know what the previous projection
305            was.
306            (MapCanvas.SetMap): Unsubscribe and subscribe to
307            LAYER_PROJECTION_CHANGED events.
308            (MapCanvas.projection_changed): Split into two methods that respond
309            to map and layer projection changes.
310            (MapCanvas.map_projection_changed): New. Takes the current view and
311            projects it using the new projection. This does not cause the
312            map to be redrawn at full extent.
313            (MapCanvas.layer_projection_changed): New. Cause a redraw which
314            will draw each layer in its new projection.
315            
316            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
317            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
318            under Windows.
319            
320            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
321            to twice sizeof(void*) because there are two digits for each
322            hex byte.
323    
324    2003-06-16  Bernhard Herzog  <[email protected]>
325    
326            Update to the layer interface: Direct access to the table,
327            shapetable, shapefile and filename attributes is now actively
328            deprecated by issuing deprecation warnings for all places where
329            this happens.
330    
331            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
332            to the instance variables table, shapetable, shapefile and
333            filename via __getattr__ so that we can issue a deprecation
334            warning.
335            (Layer.SetShapeStore): Don't set the deprecated instance variables
336            any more
337            (Layer.SetShapeStore): Don't use deprecated layer instance
338            variables
339            (Layer.Destroy): No need to explicitly remove the instance
340            variables any more
341            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
342            instance variables
343    
344            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
345            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
346            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
347            use deprecated layer instance variables
348    
349            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
350            deprecated layer instance variables
351    
352            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
353            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
354            instance variables
355    
356            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
357            deprecated layer instance variables
358    
359            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
360            deprecated layer instance variables
361    
362            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
363            deprecated layer instance variables
364    
365            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
366            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
367            variables
368    
369            * test/runtests.py (main): Turn Thuban's deprecation warnings into
370            errors so that they're cought by the tests
371    
372            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
373            layer instance variables
374    
375    2003-06-16  Jonathan Coles   <[email protected]>
376    
377            Fix a problem under Windows whereby if the user double-clicks on a
378            layer in the legend that tree item will expand or collapse as well
379            as open the layer properties dialog. The state of the tree item
380            should not be affected.
381    
382            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
383            preventExpandCollapse and subscribe to expanding and collapsing
384            events.
385            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
386            collapsing events and will veto the event if it has been triggered
387            by the user double clicking on a layer.
388            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
389            that an expanding/collapsing event should be vetoed.
390    
391    2003-06-13  Bernhard Herzog  <[email protected]>
392    
393            * Thuban/UI/classifier.py (Classifier.OnClose)
394            (Classifier.map_layers_removed)
395            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
396            in OnClose and not in map_layers_removed or
397            layer_shapestore_replaced to make sure it always happens when the
398            dialog is closed

401    
402            This puts back a fix for Windows where a panel is needed so that
403            the background of the table view appears correctly.
404    
405            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
406            object that can be used by derived classes to place any
407            controls (including the grid) onto.
408            (QueryTableFrame.__init__): Use the panel as the parent window
409            for all the controls. Reparent the grid so that the panel is
410            the parent. Call UpdateStatusText() to correctly initialize
411            the status bar.
412    
413    2003-06-13  Jonathan Coles   <[email protected]>
414    
415            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
416            from wxFrame (as opposed to wxDialog like the other classes)
417            but otherwise behaves like the other classes. This is needed
418            for the TableView which isn't really a dialog and needs to
419            have a status bar and control buttons.
420    
421            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
422            instance variable to keep track of how many rows are selected.
423            Subscribe once to the the events we are interested in.
424            (ThubanGrid.OnRangeSelect): Only handle event if event handling
425            hasn't been turned off.
426            (ThubanGrid.OnSelectCell): Only handle event if event handling
427            hasn't been turned off.
428            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
429            as an event listener (which changes the event handler stack)
430            simply set an instance variable to False. This is checked in
431            the event handlers.
432            (ThubanGrid.GetNumberSelected): Return the number of currently
433            selected rows.
434            (TableFrame): Inherit from ThubanFrame so we can have a
435            status bar and control buttons.
436            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
437            Explicitly set which items are selected in the operator choice and
438            action choice so there is always a valid selection. Fixes RTbug #1941.
439            Subscribe to grid cell selection events so we can update the
440            status bar.
441            (QueryTableFrame.UpdateStatusText): Update the status bar with
442            how many rows are in the grid, how many columns, and how many
443            rows are selected.
444            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
445            Call UpdateStatusText when cells are (de)selected.
446            (QueryTableFrame.OnQuery): Use the string value in the value
447            combo if either the selected item index is 0 or if the string
448            cannot be found in the predefined list (this happens if the
449            user changes the text). Fixes RTbug #1940.
450            Only turn off the grid event listeners if there a query comes
451            back with a none empty list of ids. in the case that the list
452            is empty this causes a grid.ClearSelection() call to actually
453            clear the grid selection which causes the selected items in
454            the map to be deselected. Fixes RTbug #1939.
455    
456            * test/test_save.py (XMLWriterTest.Encode): Check return values.
457            Fixes RTbug #1851.
458    
459    2003-06-13  Bernhard Herzog  <[email protected]>
460    
461            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
462            self.selected_shape with the current selection to make sure the
463            contents of the dialog are up to date when it's shown for the
464            first time.
465            The dialog used to work without this by luck. The recent fix to
466            the connector module 'broke' a 'feature' the identify view was
467            relying on, i.e that subscribing to a message in response to
468            receiving a message of that type would mean that the new
469            subscriber would also be called for the same message.
470            
471    2003-06-12  Jonathan Coles   <[email protected]>
472    
473            * extensions/thuban/gdalwarp.cpp: Removed debug printing as
474            the image is rendered. Fixes RTbug #1937.
475    
476    2003-06-12  Jonathan Coles   <[email protected]>
477    
478            * Thuban/Lib/fileutil.py: As is done under Windows, create the
479            user directory if it doesn't exist on a posix system.
480            Fixes RTbug #1815.
481    
482            * Thuban/Model/resource.py (get_user_proj_files): Moved the
483            called to get_application_dir here, so that the directory
484            will only be called if this method is invoked.
485    
486            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
487            the projfilepath if no projection is selected.
488    
489    2003-06-12  Jonathan Coles   <[email protected]>
490    
491            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
492            the scalebar if the current map has no projection set.
493    
494            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
495            projfilepath label to just the basename of the projection file
496            rather than include the entire path.
497    
498            * Thuban/Model/resource.py: Fix missed proj functions that
499            needed to be renamed.
500    
501    2003-06-12  Jonathan Coles   <[email protected]>
502    
503            * Thuban/Model/classification.py: Removed assert statements that
504            tested if the variable was an instance of Color.
505    
506            * Thuban/Model/color.py (Color): Remove commented code that isn't
507            used.
508            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
509            Fixes RTbug #1835.
510            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
511            Needed now that the class doesn't inherit from Color.
512    
513    2003-06-12  Jonathan Coles   <[email protected]>
514    
515            * test/test_save.py (XMLWriterTest.testEncode): Explicitly
516            check unicode strings.
517    
518            * test/test_layer.py: Check for existence of gdal.
519    
520    2003-06-12  Jonathan Coles   <[email protected]>
521        
522            * Thuban/Model/xmlreader.py: New. Contains the XMLReader class
523            that was in load.py
524    
525            * Thuban/Model/xmlwriter.py: New. Contains the XMLWriter class
526            that was in save.py
527    
528    2003-06-12  Jonathan Coles   <[email protected]>
529    
530            This is largely a collection of bug fixes. We also handle the
531            case where gdal is not on the system. The XMLReader and XMLWriter
532            classes were moved into there own files to resolve some circular
533            import references and because they shouldn't really be in the
534            file that is dediciated to reading/writing session files since
535            they are also used elsewhere.
536    
537            * Thuban/Model/classgen.py: Renamed functions to follow the
538            function_names_with_underscores style. Fixes RTbug #1903.
539            (calculate_quantiles): Raise ValueError if 'percents' is invalid.
540    
541            * Thuban/Model/layer.py: Import gdal only if it available.

574            library is available. Addresses RTbug #1877.
575    
576            * Thuban/UI/application.py (ThubanApplication.OpenSession):
577            Display a message box if the gdal library is not available, but

580            * Thuban/UI/classgen.py: Use renamed projection resource functions.
581            (GenUniformPanel.__CalcStepping): Fix a slight discrepency
582            when using integers versus floats.
583    
584            * Thuban/UI/mainwindow.py (_has_gdal_support): New. Used to
585            determine if the "Add Image Layer" menu option should be
586            greyed out or not. Addresses RTbug #1877.
587    
588            * Thuban/UI/projdialog.py: Use renamed projection resource functions.
589    
590            * Thuban/UI/renderer.py (MapRenderer.render_map): Only try to

638            dialog is showing is removed.
639    
640    2003-06-10  Bernhard Herzog  <[email protected]>
641    
642            * Thuban/Lib/connector.py (Connector.Issue): Iterate over a copy
643            of the receivers list so that unsubscribing in a receiver doesn't

647            (ConnectorTest.test_disconnect_in_receiver): New. Test whether

655    
656            * Thuban/Model/layer.py (Layer.SetShapeStore): Send

658            LAYER_CHANGED will still be sent if the classification changes.
659    
660            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
661            parameter so we can subscribe to some of its messages
662            (Classifier.__init__): Subscribe to the map's MAP_LAYERS_REMOVED
663            and the layer's LAYER_SHAPESTORE_REPLACED

665            subscribed to in __init__
666            (Classifier.map_layers_removed)

698    
699    2003-06-05  Frank Koormann  <[email protected]>
700    
701            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
702            once on initialisation (Former implementation resulted in multiple
703            entries for each projection).
704            (ProjFrame.__FillAvailList): selectProj as second optional parameter,
705            if set, select the projection found under the specified name. This
706            overwrites any other selection estimate.

708            (ProjFrame._OnSave, ProjFrame._OnAddToList):
709            Updated call of ProjFrame.__FillAvailList
710            (LCCPanel._DoLayout): Moved parameter controls in more common order.
711    
712            * Resources/Projections/defaults.proj: Extended defaults representing

715    2003-06-05  Frank Koormann  <[email protected]>
716    
717            * Thuban/UI/identifyview.py (IdentifyView.__init__):
718            Use ListCtrl instead of GridCtrl
719    
720            * Thuban/Model/resource.py:
721            Guess location of .thuban directory from tempdir parent directory.
722    
723            * Thuban/UI/application.py (ThubanApplication.read_startup_files):
724            Guess location of .thuban directory from tempdir parent directory.
725    
726    2003-06-04  Bernhard Herzog  <[email protected]>
727    
728            Do not cache the values returned by the tree widget's
729            GetFirstChild and GetNextChild methods because it led to lots of
730            segfaults. The new way requires more brute force but is more
731            reliable.
732    
733            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
734            variable layer2id

736            layer2id tried to accomplish
737            (LegendTree._OnMsgLayerChanged)
738            (LegendTree._OnMsgLayerTitleChanged, LegendTree.__ShowHideLayer):
739            Use find_layer instead of layer2id
740            (LegendTree.__RemoveLayer, LegendTree.__AddLayer): No need to
741            update layer2id anymore
742            (LegendTree._OnMsgMapLayersRemoved)
743            (LegendTree._OnMsgMapLayersAdded): Get by without layer2id.

745    2003-06-03  Thomas Koester  <[email protected]>
746    
747            * Thuban/Model/classgen.py (GenQuantiles0): New function.
748    
749    2003-06-02  Bernhard Herzog  <[email protected]>
750    
751            * Thuban/UI/mainwindow.py (layer_rename command, table_rename command):

760            set the modified flag
761

763            whether the modified flag is set properly
764    
765            * Thuban/Model/base.py (TitledObject.SetTitle): Call changed
766            instead of issue so that the modified flags get updated.
767    
768            * test/test_base.py (SomeTitledObject): Derive from Modifiable
769            instead of Publisher to reflect reality better and to accomodate
770            the fact that SetTitle now calls changed instead of issue
771    
772    2003-06-02  Bernhard Herzog  <[email protected]>
773    
774            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource
775            acquisition has to happen before the try in a try-finally.
776    
777    2003-06-02  Bernhard Herzog  <[email protected]>
778    
779            * Thuban/UI/legend.py (LegendTree._OnMsgMapLayersRemoved): It's
780            possible that a layer is removed that is not currently selected in

785            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
786            variables to None that have direct or indirect references to

830    
831            * Thuban/UI/legend.py: The legend was cleared and repopulated any

863            to be compiled as a standalone app. Now the code can only be
864            called from Python which simplifies the parameter passing.
865            (ProjectRasterFile): Handle Python arguments. Remove code that
866            checks for a destination dataset. Add more clean up code.
867    
868            * test/test_map.py (TestMapWithContents.test_raise_layer_top,

1167    2003-05-23  Jan-Oliver Wagner <[email protected]>
1168    
1169            Give all tables a title via mix-in TitledObject.LayerShowTable
1170    
1171            * Thuban/Model/base.py (TitledObject.SetTitle): Call method 'issue'
1172            only if it exists.
1173    
1174            * Thuban/Model/table.py (DBFTable, MemoryTable): mix-in TitledObject
1175            and call its init-method with a default title. Remove Title() method.
1176    
1177            * Thuban/Model/transientdb.py (TransientTable, TransientJoinedTable,
1178            AutoTransientTable): mix-in TitledObject and call its init-method with
1179            a default title. Remove Title() method.
1180    
1181    2003-05-23  Bernhard Herzog  <[email protected]>
1182    
1183            * Thuban/Model/session.py (Session.AddShapeStore): Define
1184            AddShapeStore analogously to AddTable.
1185    
1186            * test/test_session.py (TestSessionSimple.test_add_shapestore):
1187            New. Test for AddShapeStore
1188    
1189    2003-05-23  Jan-Oliver Wagner <[email protected]>
1190    
1191            Introducing QueryTableFrame and a very coarse ShowTable implementation.
1192    
1193            * Thuban/UI/tableview.py (LayerTableFrame, QueryTableFrame): Split the
1194            class LayerTableFrame into two classes, LayerTableFrame and QueryTableFrame.
1195            The latter implements the selection GUI without dependency on a layer.
1196            LayerTableFrame now is derived from QueryTableFrame and connects
1197            to a layer.
1198    
1199            * Thuban/UI/mainwindow.py (MainWindow.TableShow): A very coarse
1200            implementation that still needs work.
1201    
1202            * Thuban/Model/layer.py (Layer.TreeInfo): Added filename.
1203    
1204    2003-05-22  Frank Koormann  <[email protected]>
1205    
1206            * Thuban/Model/transientdb.py (TransientJoinedTable.__init__):
1207            Added "outer_join = False" as optional parameter.
1208            (TransientJoinedTable.create): If outer join is true, perform a
1209            "LEFT OUTER JOIN" instead of "JOIN", which preserves all records of
1210            the left table. Records not matching are filled with 0 / None.
1211    
1212            * Thuban/UI/join.py (JoinDialog.__init__): Checkbox for outer join.
1213            (JoinDialog.OnJoin): Consider outer join check box.
1214    
1215    2003-05-22  Bernhard Herzog  <[email protected]>
1216    
1217            * Thuban/UI/join.py (JoinDialog.OnJoin): Use exc_info in a
1218            somewhat safer way. Storing the traceback in a local variable can
1219            lead to memory leaks
1220    
1221    2003-05-22  Bernhard Herzog  <[email protected]>
1222    
1223            * Thuban/UI/join.py (JoinDialog.OnJoin): Make sure to really call
1224            the wxMessageDialog's Destroy() method.
1225    
1226    2003-05-22  Frank Koormann  <[email protected]>
1227    
1228            * Thuban/UI/join.py (JoinDialog.__init__): Make use of
1229            TransientTable.Title()
1230    
1231    2003-05-22  Frank Koormann  <[email protected]>
1232    
1233            Join Dialog, initial version.
1234    
1235            * Thuban/UI/mainwindow.py (MainWindow.TableJoin): Removed print.
1236    
1237            * Thuban/UI/join.py (JoinDialog): Functional implementation of
1238            former framework. Renamed Table1/Table2 to LeftTable/RightTable
1239            in all occurences.
1240    
1241            * Thuban/Model/transientdb.py (TransientJoinedTable.__doc__):
1242            Typo fixed.
1243    
1244    2003-05-22  Bernhard Herzog  <[email protected]>
1245    
1246            Give the tables titles so that the GUI can display more meaningful
1247            names. For now the titles are fixed but depend on e.g. filenames
1248            or the titles of the joined tables.
1249    
1250            * Thuban/Model/transientdb.py (TransientTable.Title)
1251            (TransientJoinedTable.Title, AutoTransientTable.Title): New.
1252    
1253            * Thuban/Model/table.py (DBFTable.Title, MemoryTable.Title): New.
1254    
1255            * test/test_transientdb.py
1256            (TestTransientTable.test_auto_transient_table_title): New. Test
1257            for the Title method
1258            (TestTransientTable.test_transient_joined_table)
1259            (TestTransientTable.test_transient_table): Add test for the Title
1260            methods
1261    
1262            * test/test_memory_table.py (TestMemoryTable.test_title): New.
1263            Test for the Title method
1264    
1265            * test/test_dbf_table.py (TestDBFTable.test_title): New. Test for
1266            the Title method
1267    
1268    2003-05-22  Bernhard Herzog  <[email protected]>
1269    
1270            * test/test_layer.py (TestLayer.setUp, TestLayer.tearDown):
1271            Provide a better way to destroy the layers
1272            (TestLayer.test_base_layer, TestLayer.test_arc_layer)

1279            * Thuban/Model/layer.py (Layer.SetShapeStore): Only set the
1280            filename if the shape store actually has one.
1281    
1282    2003-05-22  Bernhard Herzog  <[email protected]>
1283    
1284            * Thuban/Model/table.py (DBFTable.FileName): New. Accessor method
1285            for the filename
1286    
1287            * test/test_dbf_table.py (TestDBFTable.test_filename): New. Test
1288            for the FileName method
1289            (TestDBFTableWriting.test_write): Fix spelling of filename
1290    
1291    2003-05-22  Thomas Koester  <[email protected]>
1292    
1293            * Thuban/Model/range.py, test/test_range.py: Brought over new Range
1294            from SciParam that now really is immutable.
1295    
1296    2003-05-22  Frank Koormann  <[email protected]>
1297    
1298            Layer Top/Bottom placement added to legend.
1299    
1300            * Thuban/UI/legend.py
1301            (LegendPanel._OnMoveTop(), LayerPanel._OnMoveBottom): New, methods
1302            bound to tool events.
1303            (LegendTree.MoveCurrentItemTop(), LegendTree.MoveCurrentItemBottom):
1304            New, methods binding the event methods with the map methods.
1305    
1306            * Thuban/Model/map.py (Map.TopLayer(), Map.BottomLayer()): New, place
1307            layer at top/bottom of layer stack.
1308    
1309            * Resources/Bitmaps/top_layer.xpm: New button icon.
1310    
1311            * Resources/Bitmaps/bottom_layer.xpm: New button icon.
1312    
1313    2003-05-22  Bernhard Herzog  <[email protected]>
1314    
1315            * Thuban/Model/session.py (Session.RemoveTable): New method to
1316            remove tables
1317    
1318            * test/test_session.py (TestSessionSimple.test_remove_table): New.
1319            Test for RemoveTable
1320    
1321    2003-05-22  Thomas Koester  <[email protected]>
1322    
1323            * Thuban/Model/classgen.py: Added short module doc string and CVS id.
1324            (ClassGenerator.GenUniformDistribution): Use new Range __init__, too.
1325    
1326    2003-05-22  Bernhard Herzog  <[email protected]>
1327    
1328            Implement a way to discover dependencies between tables and
1329            shapestores.
1330    
1331            * Thuban/Model/transientdb.py (TransientTableBase.Dependencies)
1332            (TransientJoinedTable.Dependencies)
1333            (AutoTransientTable.SimpleQuery): New. Implement the dependencies
1334            interface
1335            (TransientJoinedTable.__init__): Keep tack of the original table
1336            objects in addition to the corresponding transient tables.
1337    
1338            * Thuban/Model/table.py (DBFTable.Dependencies)
1339            (MemoryTable.Dependencies): New. Implement the dependencies
1340            interface
1341    
1342            * Thuban/Model/data.py (ShapeTable): New. Helper class for
1343            ShapefileStore
1344            (ShapefileStore.__init__): Use ShapeTable instead of
1345            AutoTransientTable
1346            (ShapefileStore.Table, ShapefileStore.Shapefile): Add doc-strings
1347            (ShapefileStore.FileName, ShapefileStore.FileType): New. Accessor
1348            methods for filename and type
1349            (ShapefileStore.Dependencies): New. Implement the dependencies
1350            interface
1351            (DerivedShapeStore): New class to replace SimpleStore. The main
1352            difference to SimpleStore is that it depends not on a shapefile
1353            but another shapestore which expresses the dependencies a bit
1354            better
1355            (SimpleStore.__init__): Add deprecation warning.
1356    
1357            * test/test_dbf_table.py (TestDBFTable.test_dependencies): New.

1361            New. Test for the Dependencies method.
1362    
1363            * test/test_transientdb.py
1364            (TestTransientTable.test_auto_transient_table_dependencies): New.
1365            Test for the Dependencies method.
1366            (TestTransientTable.test_transient_joined_table): Add test for the
1367            Dependencies method.
1368    
1369            * test/test_session.py (TestSessionSimple.setUp)
1370            (TestSessionSimple.tearDown): New. Implement a better way to
1371            destroy the sessions.
1372            (TestSessionSimple.test_initial_state)
1373            (TestSessionSimple.test_add_table): Bind session to self.session
1374            so that it's destroyed by tearDown
1375            (TestSessionSimple.test_open_shapefile): New. Test for
1376            OpenShapefile and the object it returns
1377    
1378    2003-05-22  Bernhard Herzog  <[email protected]>
1379    
1380            * Thuban/Model/session.py (Session.AddTable): New method to
1381            register tables with the session.
1382            (Session.Tables): Return the tables registered with AddTable too.
1383    
1384            * test/test_session.py (TestSessionSimple.test_add_table): New.
1385            Test case for the AddTable method
1386    
1387    2003-05-22  Frank Koormann  <[email protected]>
1388    
1389            UI polishing updates: Place main buttons (OK, Cancel, etc) in the
1390            lower right corner, center labels for selections, initialize controls
1391            in reasonable order for keyboard navigation.
1392    
1393            * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
1394            (ProjFrame.__DoOnProjAvail): Determine position of current projection
1395            using the wxListBox.FindString() method. Still a problem (#1886)
1396    
1397            * Thuban/UI/classifier.py
1398            (Classifier.__init__, SelectPropertiesDialog.__init__)
1399    
1400            * Thuban/UI/classgen.py (ClassGenDialog.__init__,
1401            (ClassGenDialog.__DoOnGenTypeSelect): Moved initialization of the
1402            different classification types from here to __init__.
1403            (GenUniquePanel.__init__): Set the column width of the first field
1404            in the Field ListCtrl to the full width.
1405    
1406            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Rename 'Save As'
1407            Button to 'Export'. Center Buttons in Selection Box, set Focus to
1408            Grid.
1409            (LayerTableFrame.OnKeyDown()): New, bound to the grid with EVT_KEY_DOWN,
1410            changes focus to the Selection when pressing "Alt-S".
1411    
1412            * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
1413            the text if not visible. The italic font sometimes exceeds the
1414            rendering area.
1415    
1416    2003-05-21  Jonathan Coles   <[email protected]>
1417    
1418            * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
1419            to OnClose so that Thuban closes correctly.
1420    
1421            * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
1422            DockFrame.OnClose, not DockFrame._OnClose.
1423    
1424    2003-05-21  Jonathan Coles   <[email protected]>
1425    
1426            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
1427            references to 'inf' and use new Range __init__ to pass floats
1428            directly rather than converting them to strings first.
1429            Fixes RTBug #1876.
1430    
1431            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
1432            Use new Range ___init__ to pass floats.
1433    
1434            * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
1435            filename is a valid image file. Throw IOError otherwise.
1436    
1437            * Thuban/Model/range.py: Brought over new Range from SciParam that
1438            is immutable and has an __init__ which can accept floats.
1439    
1440            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
1441            into try block. AddLayer doesn't throw any exceptions anymore.
1442            (MainWindow.AddRasterLayer): Move constructor of RasterLayer into
1443            try block.
1444    
1445            * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as
1446            the first item in choices. Fixes RTBug #1882.
1447    
1448            * Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale
1449            has gone to 0 which is a serious problem. abort.
1450            (MapRenderer.draw_raster_layer): Catch IOError seperately and
1451            print the error from GDAL.
1452    
1453            * Thuban/UI/tableview.py (TableGrid.__init__): Call
1454            ToggleEventListeners to turn on listening.
1455            (TableGrid.ToggleEventListeners): New. Turns event listening on
1456            and off so as to prevent excessive messages.
1457            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
1458            to suppress excessive messages when selecting many rows.
1459            Fixes RTBug #1880.
1460    
1461            * Thuban/UI/view.py: Added checks against if scale == 0. This
1462            is a serious problem that can occur when an image without
1463            geo data is loading and causes the map projection bounds to
1464            go to infinity. Right now, the solution is to simply try
1465            to recover.
1466    
1467            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
1468            to set the MFILEReceiver attributes even if the data is NULL.
1469    
1470            * extensions/thuban/gdalwarp.cpp: Improved the error handling
1471            and passed GDAL messages back up to the Python layer. Also
1472            tried to fix some memory leaks that were present in the original
1473            utility but didn't matter because the program aborted.
1474    
1475            * test/test_range.py: Copied over tests from SciParam. Removed
1476            tests against importing. Fixes RTBug #1867.
1477    
1478    2003-05-21  Bernhard Herzog  <[email protected]>
1479    
1480            * test/test_load.py: Remove unused imports and restructure the
1481            test code
1482            (LoadSessionTest): Split into one class for each test and turn
1483            LoadSessionTest itself into the base class for all such session
1484            tests.
1485            (ClassificationTest): New base class for load tests that test
1486            classifications
1487            (TestSingleLayer, TestLayerVisibility, TestClassification)
1488            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
1489            for the individual tests
1490    
1491            * test/support.py (FileLoadTestCase.filename): New base class for
1492            file loading tests
1493    
1494    2003-05-21  Jan-Oliver Wagner <[email protected]>
1495    
1496            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
1497            Mercator' to 'UTM Zone 32' as a more convenient example.
1498            Added 'Gauss Krueger Zone 6'.
1499    
1500            * Data/iceland_sample_raster.thuban: political polygon now
1501            filled transparent to have the raster image visible at once.
1502    
1503    2003-05-21  Frank Koormann  <[email protected]>
1504    
1505            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
1506            OnClose() to keep in sync with extensions. Internally Thuban
1507            still uses "underscored" names.
1508    
1509    2003-05-20  Jonathan Coles   <[email protected]>
1510    
1511            This puts back Raster layer support. These layers support projections
1512            through the GDAL library. Currently, the CVS version is being used.
1513            There are no Debian packages available although this may change soon.
1514            A GDAL driver was extended to support writing to memory rather to
1515            files.
1516    
1517            There is still some work that needs to be done, such as some error
1518            handling when loading invalid images or when there is a problem
1519            projecting the image. This putback simply checks in the majority
1520            of the work.
1521    
1522            * setup.py: Add gdalwarp library extension.
1523    
1524            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
1525            Defaults to False, but can be overridden by subclasses if they
1526            support classification.
1527            (RasterLayer): New. Defines a new layer that represents an
1528            image.
1529    
1530            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
1531            tag handler.
1532            (SessionLoader.start_layer): Encode the filename.
1533            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
1534            New. Supports reading a rasterlayer tag.
1535    
1536            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
1537    
1538            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
1539            get a string in Latin1. If we get such as string convert it to
1540            unicode first, otherwise leave if alone before encoding.
1541            (SessionSaver.write_layer): Add support for writing both Layers
1542            and RasterLayers.
1543    
1544            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
1545            The right argument may not be a string, it could also be a Column.
1546    
1547            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):

1549    
1550            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
1551            the dialog is constructed so that we can support layers that
1552            do not have classifications.
1553            (Classifier._OnTry): Only build a classification if the layer
1554            supports one.
1555    
1556            * Thuban/UI/legend.py: Change all checks that a layer is an
1557            instance of Layer into checks against BaseLayer.

1559            the layer supports classification.
1560    
1561            * Thuban/UI/mainwindow.py (MainWindow.NewSession,

1563            user chooses Cancel when they are asked to save changes.
1564            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
1565            user to select an image file. Create a new RasterLayer and add
1566            it to the map.

1568            * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
1569            for rendering RasterLayer layers.
1570            (MapRenderer.draw_raster_layer): Actually method that calls
1571            the GDALWarp python wrapper and constructs an image from the
1572            data returned.
1573    
1574            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the

1577    
1578            * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
1579            how small the scale can get. This still needs more testing.
