2    
3            * test/support.py (FloatComparisonMixin.assertPointListEquals):
4            New. This method was used in various derived classes, but it's
5            better to have it here.
6    
7            * test/test_shapefilestore.py
8            (ShapefileStoreTests.assertPointListEquals): Removed. It's now in
9            FloatComparisonMixin
10    
11            * test/test_layer.py (TestLayer.assertPointListEquals): Removed.
12            It's now in FloatComparisonMixin
13    
14            * test/test_derivedshapestore.py
15            (TestDerivedShapeStore.assertPointListEquals): Removed. It's now
16            in FloatComparisonMixin
17    
18    2003-08-11  Bernhard Herzog  <[email protected]>
19    
20            * Thuban/UI/join.py (JoinDialog.OnJoin): Add missing space to
21            error message
22    
23    2003-08-08  Jan-Oliver Wagner <[email protected]>
24

26            with version number.
27            Changed title to reflect version number of Thuban.
28    
29    2003-08-08  Jan-Oliver Wagner <[email protected]>
30    
31            * Thuban/UI/about.py (About.__init__): Reworked the hall of fame. Now
32            the list corresponds to the "About" web page.
33    
34    2003-08-08  Bernhard Herzog  <[email protected]>
35    
36            * Thuban/UI/projdialog.py (UTMProposeZoneDialog.dialogLayout):
37            Make sure translated strings are recognized as one string literal.
38    
39            * Thuban/UI/proj4dialog.py (UTMProposeZoneDialog.dialogLayout):

46            sure translated strings are recognized as one string literal.
47    
48    2003-08-07  Bernhard Herzog  <[email protected]>
49    
50            * Thuban/Model/data.py (DerivedShapeStore.RawShapeFormat): New.
51            Simply delegates to the original shapestore.
52    
53            * test/test_derivedshapestore.py
54            (TestDerivedShapeStore.test_raw_format): New. Test case for
55            DerivedShapeStore.RawShapeFormat
56    
57    2003-08-07  Bernhard Herzog  <[email protected]>
58    
59            Add raw data interface to shape objects.
60    
61            * Thuban/Model/data.py (ShapefileShape, Shape): Rname the shape
62            class to ShapefileShape which now holds shapefile specific
63            information.
64            (ShapefileShape.compute_bbox): Simplified to not cache any
65            information. The way this method is used that shouldn't matter
66            performance wise.
67            (ShapefileShape.RawData): New. Return the shapeid which is the raw
68            data format for shapes from shapefiles.
69            (ShapefileStore.RawShapeFormat): New. Return the raw datatype used
70            in the shape objects returned by a shapestore. For a
71            ShapefileStore this is always RAW_SHAPEFILE.
72            (RAW_PYTHON, RAW_SHAPEFILE): Constants for the RawShapeFormat
73            method.
74    
75            * test/test_shapefilestore.py
76            (TestShapefileStore.test_raw_format): New test to test the raw
77            format feature of shapes.
78    
79            * Thuban/Model/layer.py: Remove the unused import of Shape from
80            data. It was only there for interface compatibility but it's not
81            used inside of Thuban and the generic Shape class has gone away.
82    
83            * Thuban/UI/renderer.py (MapRenderer.low_level_renderer): Check
84            the raw data format and only use an optimized version of its a
85            shapefile.
86    
87    2003-08-07  Bernhard Herzog  <[email protected]>
88    
89            * test/test_baserenderer.py (SimpleShape): Shape class for the
90            tests.
91            (SimpleShapeStore.Shape): Use SimpleShape instead of
92            Thuban.Model.data.Shape to make the tests independed of the coming
93            changes.
94    
95    2003-08-07  Bernhard Herzog  <[email protected]>
96    
97            * test/support.py (SkipTest, ThubanTestResult, ThubanTestRunner)
98            (ThubanTestProgram): New classes that extend the respective
99            classes from unittest. These new version support skipping tests
100            under certain expected conditions. In the Thuban test suite we
101            uses this for tests that require the optional gdal support.
102            (run_tests): Use ThubanTestProgram instead of the unittest.main()
103    
104            * test/runtests.py (main): Use the new ThubanTestRunner instead of
105            the normal one from unittest
106    
107            * test/test_layer.py (TestLayer.test_raster_layer): If this test
108            is not run because gdal support isn't available report this to the
109            runner.
110    
111            * test/test_baserenderer.py
112            (TestBaseRenderer.test_raster_no_projection): Do not run this test
113            if gdal support isn't available and report this to the runner.
114    
115    2003-08-06  Bernhard Herzog  <[email protected]>
116    
117            Rearrange the renderers a bit, partly in preparation for changes
118            required for the postgis merge, partly to make it more testable.
119            Also make the representation of coordinates in Shapes more
120            consistent.
121    
122            * Thuban/UI/renderer.py (MapRenderer): Most of the code/methods in
123            this class is now in BaseRenderer. This class is now practically
124            only a specialization of BaseRenderer for rendering to an actual
125            wx DC.
126            (ScreenRenderer.draw_shape_layer): Use self.low_level_renderer()
127            to get the shapetype specific rendering functions.
128    
129            * Thuban/UI/baserenderer.py: New file with the basic rendering
130            logic. The code in this file is completely independend of wx.
131            (BaseRenderer): Class with the basic rendering logic
132    
133            * test/test_baserenderer.py: New. Test cases for BaseRenderer
134    
135            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
136            error_on_redraw to guard agains endless loops and stack overflows
137            when there's a bug in the rendering code that raises exceptions.
138            (MapCanvas.OnIdle, MapCanvas._do_redraw): Split the actual
139            rendering into a separate method _do_redraw so that error handling
140            is a bit easier. When an exception occurs, set error_on_redraw to
141            true. When it's true on entry to OnIdle do nothing and return
142            immediately.
143    
144            * Thuban/Model/data.py (ShapefileStore.Shape): For consistency, a
145            Shape object will always have the coordinates as a list of list of
146            coordinate pairs (tuples).
147            (Shape.compute_bbox): Adapt to new representation.
148    
149            * Thuban/UI/viewport.py (ViewPort.find_shape_at)

153            * test/test_shapefilestore.py
154            (ShapefileStoreTests.assertFloatTuplesEqual)
155            (ShapefileStoreTests.assertPointListEquals): Rename to
156            assertPointListEquals and change purpose to checking equality of
157            the lists returned by Shape.Points().
158            (TestShapefileStoreArc.test_shape)
159            (TestShapefileStorePolygon.test_shape)
160            (TestShapefileStorePoint.test_shape): Use the new
161            assertPointListEquals instead of assertFloatTuplesEqual
162    
163            * test/test_layer.py (TestLayer.assertFloatTuplesEqual)
164            (TestLayer.assertPointListEquals): Rename to assertPointListEquals
165            and change purpose to checking equality of the lists returned by
166            Shape.Points().
167            (TestLayer.test_arc_layer, TestLayer.test_arc_layer)
168            (TestLayer.test_polygon_layer, TestLayer.test_point_layer)
169            (TestLayer.test_derived_store): Use the new assertPointListEquals
170            instead of assertFloatTuplesEqual
171    
172            * test/test_derivedshapestore.py
173            (TestDerivedShapeStore.assertFloatTuplesEqual)
174            (TestDerivedShapeStore.assertPointListEquals): Rename to
175            assertPointListEquals and change purpose to checking equality of
176            the lists returned by Shape.Points().
177            (TestDerivedShapeStore.test_shape): Use the new
178            assertPointListEquals instead of assertFloatTuplesEqual
179    
180    2003-08-06  Jan-Oliver Wagner <[email protected]>
181    
182            * Thuban/UI/projdialog.py (UTMPanel._OnPropose): Added test for
183            a bounding box. A dialog is raised in case, no bounding box
184            is found. This fixes bug #2043:
185            https://intevation.de/rt/webrt?serial_num=2043
186    
187    2003-08-05  Bernhard Herzog  <[email protected]>
188    
189            * Thuban/Model/color.py (Color.__repr__): Make the repr of a color
190            object look like a Color instantiation. Formerly it looked like a
191            tuple.
192    
193            * test/test_color.py (TestColor.test_repr)
194            (TestColor.test_equality, TestColor.test_inequality): New. test
195            some more apects of the Color class
196            (TestTransparent.test_repr, TestTransparent.test_hex)
197            (TestTransparent.test_equality): New. Test cases for the
198            Transparent object.
199    
200    2003-08-04  Jan-Oliver Wagner <[email protected]>
201    
202            * Doc/manual/thuban-manual.xml: a number of small improvements.
203            The resulting file is the version submitted for GREAT-ER II.
204    
205    2003-08-01  Bernhard Herzog  <[email protected]>
206    
207            * Thuban/UI/resource.py, Thuban/UI/projdialog.py,
208            Thuban/UI/join.py, Thuban/UI/classgen.py, Thuban/UI/about.py,
209            Thuban/Model/resource.py: Insert cvs keywords and doc-strings.
210

213            (ThubanEndBusyCursor): Add doc-strings
214    
215    2003-08-01  Bernhard Herzog  <[email protected]>
216    
217            First step towards PostGIS integration. More abstraction by movin
218            more code from the layer to the shapestore. More methods of the
219            layer are now simply delegated to the equivalent method of the
220            shapestore. The SHAPETYPE_* constants are now in data not in
221            layer.
222    
223            * Thuban/Model/data.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
224            (SHAPETYPE_POINT, Shape): Move these constants and classes from
225            layer.py to data.py
226            (ShapefileStore.__init__): More Initialization for the new methods
227            and functionality.

230            (ShapefileStore.Shape): New methods that were formerly implemented
231            in the layer.
232            (DerivedShapeStore.Shape, DerivedShapeStore.ShapesInRegion)
233            (DerivedShapeStore.ShapeType, DerivedShapeStore.NumShapes)
234            (DerivedShapeStore.BoundingBox): New. DerivedShapeStore
235            equivalents of the new shape methods. These versions are simply
236            delegated to the original shapstore.
237    
238            * Thuban/Model/layer.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
239            (SHAPETYPE_POINT, Shape): Removed. They're now in data.py
240            (Layer.SetShapeStore): Removed the initializatin of instance
241            variables that were needed for the stuff that's now in
242            ShapefileStore
243            (Layer.BoundingBox, Layer.NumShapes, Layer.ShapeType)
244            (Layer.Shape, Layer.ShapesInRegion): Simply delegate to the
245            shapestore.
246    
247            * Thuban/UI/classifier.py, Thuban/UI/renderer.py,
248            Thuban/UI/viewport.py: Import the SHAPETYPE_* constants from data
249            instead of layer.
250    
251            * test/test_shapefilestore.py: New. Tests for ShapefileStore.
252    
253            * test/test_derivedshapestore.py: New. Tests for DerivedShapeStore.
254    
255            * test/test_layer.py: Import the SHAPETYPE_* constants from data
256            instead of layer.
257            (TestLayer.test_derived_store): Remove the test for the exception
258            when instantiating the DerivedShapeStore with an incompatible
259            table which is now in test_derivedshapestore.py. Add some more
260            tests of the layer methods to determine whether they work for a
261            DerivedShapeStore as well.
262    
263    2003-07-31  Jonathan Coles   <[email protected]>
264    
265            * Doc/manual/thuban-manual.xml: Fix the list of required packages
266            by just listing the name and where they can be found.
267    
268    2003-07-31  Frank Koormann   <[email protected]>
269    
270            * Doc/manual/thuban-manual.xml:
271            Changed the screenshot elements to figure.
272            Changed some variablelist elements to itemizedlist.
273            Added section on GDAL formats.
274    
275    2003-07-31  Jonathan Coles   <[email protected]>
276    
277            * Doc/manual/thuban-manual.xml: Added a few sentences about
278            the Fix Border Color option when generating classes.
279    
280    2003-07-30  Jonathan Coles   <[email protected]>
281    
282            * Thuban/Model/classgen.py: Add docstrings. Rename specific
283            Ramp instances to use lower_case_style.
284    
285            * Thuban/UI/classgen.py: Use renamed Ramp instances.
286            
287            * Thuban/UI/classifier.py: Add docstrings.
288    
289            * Thuban/UI/dock.py: Add docstrings.
290    
291            * test/test_classgen.py: Use renamed Ramp instances.
292    
293    2003-07-30  Bernhard Herzog  <[email protected]>
294    
295            * Thuban/Lib/connector.py (QueueingPublisher): Removed. This class
296            was never used in Thuban.
297    
298    2003-07-30  Bernhard Herzog  <[email protected]>
299    
300            * Thuban/UI/join.py (JoinDialog.__init__): Use the table's Title()
301            method directly instead of going through the transient_table
302            method. This faster because transient_table may force the copy of
303            a DBF file into the transient database and setting a table's title
304            doesnm't affect the title of the associated transient table, so
305            this fixes RT #2042
306    
307            * Thuban/UI/main.py (__version__): Don't import the already
308            removed show_exception_dialog.
309    
310    2003-07-29  Jonathan Coles   <[email protected]>
311    
312            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
313            Put back this method and remove the equivalent function since we
314            are setting the exception hook from within this class (OnInit).
315    
316    2003-07-29  Jonathan Coles   <[email protected]>
317    
318            * Doc/manual/images/5_2_custom_ramp.png,
319            Doc/manual/images/5_2_quantiles.png,
320            Doc/manual/images/5_2_uniform_dist.png,
321            Doc/manual/images/5_2_unique_values.png,
322            Doc/manual/images/8_int_error.png: New screen shots.
323    
324            * Doc/manual/thuban-manual.xml: Fixed typos and wording, clarified
325            some points, and added more screen shots.
326    
327    2003-07-29  Bernhard Herzog  <[email protected]>
328    
329            * Thuban/Model/data.py: Remove the now unused import of warnings
330    
331    2003-07-29  Bernhard Herzog  <[email protected]>
332    
333            * Thuban/Model/data.py (SimpleStore): Removed. This class has been
334            deprecated since before the 0.8 release and isn't used in Thuban
335            itself anymore.
336    
337            * Thuban/Model/transientdb.py: Remove some unnecessary imports
338    
339    2003-07-29  Jonathan Coles   <[email protected]>
340    
341            * Thuban/UI/application.py (ThubanApplication.OnInit): set the
342            python exception hook here so that we are sure to catch any
343            Thuban exception that happen during initialization.
344    
345            * Thuban/UI/main.py (main): Don't set the exception hook here,
346            it will get set in ThubanApplication.OnInit.
347    
348    2003-07-29  Jonathan Coles   <[email protected]>
349                                                                                
350            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
351            Removed and called it show_exception_dialog() so that the exception
352            handler can be set before the class is created.
353                                                                                
354            * Thuban/UI/main.py (main): Install the exception handler before
355            a ThubanApplication is created.
356

399    2003-07-24  Jonathan Coles   <[email protected]>
400    
401            * Doc/manual/thuban-manual.xml: Chapter on Projection Management.
402    
403    2003-07-24  Jonathan Coles   <[email protected]>
404    
405            * Doc/manual/thuban-manual.xml: Added EPS images and wrote
406            chapter on Layer Management.
407    
408            * Doc/manual/Makefile: New. Makefile to generate all formats for the
409            manual and images.
410    
411    2003-07-24  Bernhard Herzog  <[email protected]>
412    
413            * Thuban/Model/range.py, Thuban/version.py: Remove the #! line as
414            it annoys lintian which warns about these files not being
415            executable. The #1 isn't necessary here since if you absolutely
416            must execute them you can always say "python <filename>".
417    
418            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Remove
419            superfluous code to set brush and pen for point shapes
420    
421            * Thuban/UI/viewport.py: Remove commented out code that wouldn't
422            belong in viewport anyway
423    
424    2003-07-24  Frank Koormann   <[email protected]>
425    
426            * Doc/manual/thuban-manual.xml: Added section on table management.
427    
428    2003-07-24  Bernhard Herzog  <[email protected]>
429    
430            * test/runtests.py (main): Recognize the long "verbose" option
431            correctly.
432    
433    2003-07-22  Jonathan Coles   <[email protected]>
434    
435            * Doc/manual/thuban-manual.xml: Continue to write first revision
436            of the manual.
437    
438            * Thuban/UI/renderer.py (MapRenderer.render_map): Wrap method
439            with Begin/EndDrawing() calls to ensure we aren't doing to
440            many updates to the dc during rendering.
441            (ScreenRenderer.draw_shape_layer): self.draw_point_shape takes
442            a pen and brush argument so they need to be passed to the function.
443    
444            * Thuban/UI/viewport.py (ViewPort.calc_min_max_scales): New.
445            Calculates the minimum and maximum scale values. Factored out
446            of set_view_transform so that it could be used to zoom all the
447            way into a single point.
448            (ViewPort.set_view_transform): Call calc_min_max_scales().
449            (ViewPort.FitSelectedToWindow): Zoom to the maximum scale
450            if only a single point is selected.

472    
473    2003-07-18  Bernhard Herzog  <[email protected]>
474    
475            * Thuban/UI/messages.py (MAP_REPLACED): New message.
476    
477            * Thuban/UI/viewport.py (ViewPort.SetMap): Issue MAP_REPLACED
478            after the new map has been assigned
479    
480            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages):
481            Delegate MAP_REPLACED to the canvas too
482            (MainWindow.prepare_new_session): Removed. Thanks to the new
483            MAP_REPLACED message it's no longer needed
484            (MainWindow.OpenSession, MainWindow.NewSession):
485            prepare_new_session has been removed.
486    
487            * Thuban/UI/classifier.py (Classifier.__init__): Subscribe to
488            MAP_REPLACED so that we can close the dialog if a new map is set.
489            (Classifier.unsubscribe_messages): Unsubscribe from MAP_REPLACED
490            (Classifier.map_replaced): Handle MAP_REPLACED by closing the
491            dialog

493            * test/test_viewport.py (SimpleViewPortTest)
494            (SimpleViewPortTest.test_default_size): Add doc-strings
495            (ViewPortTest.setUp): Bind map to self.map so we can use it in
496            tests. Subscribe to MAP_REPLACED messages too.
497            (ViewPortTest.tearDown): No need to explicitly unsubscribe
498            (ViewPortTest.test_set_map): New test for the SetMap method.
499    
500    2003-07-18  Bernhard Herzog  <[email protected]>
501    
502            * test/test_viewport.py (SimpleViewPortTest.test_default_size):
503            Move this test from ViewPortTest.setUp to this new separate test
504            case. setUp is not the place for the actual tests.
505            (ViewPortTest.test_inital_settings, ViewPortTest.setUp): Move some
506            more of the test from setUp to the new test test_inital_settings.
507            (ViewPortTest.test_win_to_proj, ViewPortTest.test_proj_to_win)
508            (ViewPortTest.test_proj_conv): Split test_proj_conv into
509            test_win_to_proj and test_proj_to_win and make the tests easier to
510            understand
511            (ViewPortTest.testFitRectToWindow, ViewPortTest.testZoomFactor)
512            (ViewPortTest.testZoomOutToRect, ViewPortTest.testTranslate)
513            (ViewPortTest.test_unprojected_rect_around_point)
514            (ViewPortTest.test_find_shape_at, ViewPortTest.testTools):
515            Reformat to increase readability.
516

518    
519            * Thuban/UI/view.py (MapCanvas.OnLeftDown): Capture the mouse.
520    
521    2003-07-18  Bernhard Herzog  <[email protected]>
522    
523            * test/runtests.py: The test suite can now be run without an X
524            connection. To make sure this remains true, remove the DISPLAY
525            environment variable so that an error occurs if the wxGTK is
526            imported accidentally
527    
528    2003-07-18  Bernhard Herzog  <[email protected]>
529    
530            * Thuban/UI/viewport.py: Remove unused imports
531    
532            * Thuban/UI/view.py: Remove unused imports
533    
534    2003-07-18  Bernhard Herzog  <[email protected]>
535    
536            * test/test_export.py Remove unused imports. The OutputTransform
537            function is now in viewport.py and is called output_transform
538            (TestScalebar.test_output_transform)
539            (TestScalebar.test_OutputTransform): Renamed to
540            test_output_transform and updated to use output_transform instead
541            of OutputTransform
542    
543            * Thuban/UI/view.py (OutputTransform): Moved to viewport.py and
544            renamed.
545            (MapCanvas.Export, MapPrintout.draw_on_dc): OutputTransform was
546            renamed to output_transform
547    
548            * Thuban/UI/viewport.py (OutputTransform, output_transform):
549            Rename to output_transform
550    
551    2003-07-18  Bernhard Herzog  <[email protected]>
552    
553            * Thuban/Model/layer.py (Layer.__init__): Rename
554            classificationField to classificatin_column and init it here so
555            that it can be used in SetClassificationColumn
556            (Layer.GetClassificationColumn, Layer.GetClassificationField):
557            Rename to GetClassificationColumn.
558            (Layer.SetClassificationColumn, Layer.SetClassificationField):
559            Rename to SetClassificationColumn and issue a LAYER_CHANGED
560            message if the column changes.
561            (Layer._classification_changed, Layer.ClassChanged): Rename to
562            _classification_changed. Update the callers.
563            (Layer.SetShapeStore): Further field->column renames.
564    
565            * Thuban/Model/load.py (SessionLoader.start_classification)
566            (SessionLoader.start_clpoint): Updates because of
567            field->column method name changes in the Layer class
568    
569            * Thuban/Model/save.py (SessionSaver.write_classification): Updates
570            because of field->column method name changes in the Layer class
571    
572            * Thuban/UI/classifier.py (Classifier.__init__)
573            (Classifier._OnTry, Classifier._OnRevert): Updates because of
574            field->column method name changes in the Layer class
575    
576            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Updates
577            because of field->column method name changes in the Layer class
578    
579            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Updates because
580            of field->column method name changes in the Layer class
581    
582            * test/test_save.py (SaveSessionTest.testClassifiedLayer)
583            (SaveSessionTest.testClassifiedLayer): Update because of
584            field->column method name changes in the Layer class
585    
586            * test/test_layer.py (SetShapeStoreTests.setUp)
587            (SetShapeStoreTests.test_sanity): Update because of field->column
588            method name changes in the Layer class
589            (TestLayerModification.setUp): Subscribe to LAYER_CHANGED as well
590            (TestLayerModification.test_sanity)
591            (TestLayerModification.test_initial_settings): remove unsued code
592            and rename to test_sanity.
593            (TestLayerModification.test_set_classification): New test for
594            SetClassification and SetClassificationField.
595    
596    2003-07-18  Bernhard Herzog  <[email protected]>
597    
598            * test/test_classgen.py (TestFixedRamp.test): Extend test to check
599            the non-fixed values as well. The old test would have accepted a
600            fixed ramp that only returnes the fixed properties
601    
602    2003-07-17  Jonathan Coles   <[email protected]>
603    
604            * Doc/manual/mainwindow.png, Doc/manual/mainwindow.xcf: Screen
605            shots for the manual. The XCF file is the source image and
606            has additional layers to support changes.
607    
608            * Doc/manual/thuban-manual.xml: Wrote an initial Introduction.
609    
610            * Thuban/UI/classifier.py (Classifier.__BuildClassification):
611            Return both the new class and the field name.
612    
613            * Thuban/UI/mainwindow.py (MainWindow.ToggleLegend): Don't
614            fit the map to the window as this changes any zoom level that
615            the user may have set.
616    
617    2003-07-16  Jonathan Coles   <[email protected]>
618    
619            * Thuban/Model/classgen.py (generate_singletons,
620            generate_uniform_distribution, generate_quantiles): Remove
621            fixes parameter, but maintain the same functionality by having
622            the calling function pass a FixedRamp object for the ramp.
623            (FixedRamp): New. Adapts a ramp to have fixed property values.
624    
625            * Thuban/Model/classification.py: Use new CLASS_CHANGED message.
626            (Classification): Inherit from Publisher.
627            (Classification.__init__): Remove the layer parameter.
628            Classifications no longer need to have a parent layer.
629            (Classification.GetField, Classification.GetFieldType,
630            Classification.SetFieldInfo): Removed. The field name is stored
631            in the layer, and the type can be retreived by calling
632            Layer.GetFieldType().
633            (Classification._set_layer, Classification.GetLayer): Removed.
634            Classifications no longer have a parent layer.
635    
636            * Thuban/Model/layer.py (Layer.Destroy): Unsubscribe from the
637            classification.
638            (Layer.SetShapeStore): Reset the classification first while
639            we still have the old shape store to work with.
640            (Layer.GetClassificationField, Layer.SetClassificationField):
641            New. Method for getting/setting the field to classify on.
642            (Layer.SetClassification): Simplified now that the layer
643            simply has to hold a reference to the classification and not
644            tell the classification who owns it.
645            Fixes RTbug #2023.
646    
647            * Thuban/Model/load.py (SessionLoader.start_classification):
648            Set the field name on the layer, not the classification.
649    
650            * Thuban/Model/messages.py: Add CLASS_CHANGED for when a
651            classification is modified.
652    
653            * Thuban/Model/save.py (SessionSaver.write_classification):
654            Get the field name and type from the layer.
655    
656            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Renamed
657            parameter records to rows and add docstring. Fixes RTbug #1997.
658    
659            * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Use a fixed
660            ramp when we need to fix certain values of a ramp rather than
661            using the old fixes parameter. Fixes RTbug #2024.
662    
663            * Thuban/UI/classifier.py (ClassGrid.CreateTable): Add fieldType
664            parameter.
665            (ClassTable.Reset): Add fieldType parameter and use it, rather
666            than asking the classification.
667            (Classifier.__init__): Remember the original class's field
668            and ask the layer for the field type, rather than the classification.
669            (Classifier.__SetGridTable): Retrieve the field and field type
670            for the table because they are not in the classification.
671            (Classifier._OnTry, Classifier._OnRevert): Set the classification
672            field on the layer in addition to the classification itself.
673    
674            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Get the
675            classification field from layer.
676    
677            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Get the
678            classification field from layer. Split up tests and remove
679            *-imports. Fixes RTbug #1992.
680    
681            * test/test_classgen.py (TestFixedRamp): Test for the FixedRamp class.
682    
683            * test/test_classification.py
684            (TestClassification.test_classification): Remove tests for methods
685            that no longer exist.
686    
687            * test/test_layer.py (SetShapeStoreTests.setUp): Classification
688            __init__ no longer has a field parameter, use SetClassificationField.
689            (SetShapeStoreTests.test_sanity): Use layer object to get class
690            field info.
691    
692            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Use
693            SetClassificationField on layer to set class field info.
694    
695            * test/test_viewport.py: Renamed from test/test_view.py.
696    
697    2003-07-16  Jan-Oliver Wagner <[email protected]>
698    
699            * Doc/manual/thuban-manual.xml: Added authors and an initial
700            coarse structure.
701    
702    2003-07-15  Bernhard Herzog  <[email protected]>
703    
704            * test/support.py (FloatComparisonMixin): This is a mix-in class
705            and therefore should not be derived from any other class.
706    
707            * test/test_range.py (RangeTest): FloatComparisonMixin is a
708            mix-in, so derive from TestCase as well.
709    
710    2003-07-15  Bernhard Herzog  <[email protected]>
711    
712            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Rework the
713            draw_func handling a bit to remove one layer of indirection. This
714            makes the renderer about 10% faster in the non-classifying case
715            and the code a bit cleaner
716            (MapRenderer.draw_point_shape): Add the pen and brush parameters
717            and set them in the dc. Now the draw_point_shape method and
718            wxproj's draw_polygon_shape function have basically the same
719            signature so that both can be directly used as draw_func
720    
721    2003-07-15  Bernhard Herzog  <[email protected]>
722    
723            * Thuban/Model/save.py (SessionSaver.write_classification): Encode
724            string values (in addition to the labels) as UTF 8
725    
726            * Thuban/Model/load.py (SessionLoader.start_clpoint): Decode the
727            values if the field type is string
728    
729            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Test
730            saving a session with non-ascii string classification values.
731    
732            * test/test_load.py (TestClassification.file_contents)
733            (TestClassification.test): Check for non-ascii values in string
734            classifications
735    
736    2003-07-14  Jonathan Coles   <[email protected]>
737    
738            * test/test_view.py: New. Tests for ViewPort.
739    
740    2003-07-14  Frank Koormann   <[email protected]>
741    
742            * Thuban/Model/load.py (SessionLoader.start_map): Encode map
743            title to latin1.  Fixes https://intevation.de/rt/webrt?serial_num=2013
744    
745            * test/test_load_0_8.py (TestUnicodeStrings): New, test load of
746            unicode strings from session file: session title, map title and
747            projection name.
748            
749    2003-07-10  Jonathan Coles   <[email protected]>
750    
751            * Thuban/UI/viewport.py (Tool.MouseUp): Should have called
752            drag_stop, not drag_move when the mouse is released.
753    
754    2003-07-10  Jonathan Coles   <[email protected]>
755    
756            The most important part of this is the seperation of view.py into
757            two pieces. viewport.py now has a class called ViewPort which
758            contains all the non-wx parts of view.py and can therefore be
759            tested. view.py contains only the wx-specific parts and is fairly
760            simple.
761    
762            * Thuban/UI/view.py: Stripped out all non-wx functionality. Fixes
763            RTTbug #1992.
764            * Thuban/UI/viewport.py: New. Contains non-wx view functionality.
765            RTTbug #1992.
766    
767            * Thuban/Model/classgen.py (generate_singletons,
768            generate_uniform_distribution, generate_quantiles):

862    2003-07-08  Bernhard Herzog  <[email protected]>
863    
864            * Resources/XML/thuban-0.9.dtd: New. This will become the DTD for

928            Update doc-string
929            (TransientJoinedTable.create): Do not modify the column objects of

940    
941    2003-07-02  Jonathan Coles   <[email protected]>
942    
943            * Thuban/Model/classgen.py (generate_singletons,
944            generate_uniform_distribution, generate_quantiles,
945            GenQuantiles0): Make sure maxValue isn't less than
946            one, otherwise we could divide by zero.
947    
948            * test/test_classgen.py (ClassGenTest.doClassRangeTest,
949            ClassGenTest.doClassSingleTest): Call doBoundsTest to
950            check the end classification groups against the
951            proper property values.
952            (ClassGenTest.doBoundsTest): New. Checks the first and
953            last classification groups to make sure their properties
954            are the correct upper and lower bounds for a color ramp.
955    
956    2003-07-02  Jonathan Coles   <[email protected]>
957    
958            * Thuban/Model/classgen.py (generate_singletons,
959            generate_uniform_distribution, generate_quantiles,
960            GenQuantiles0): The denominator was one to high when
961            calculating the index for the ramp causing the index
962            to never to reach one.
963    
964    2003-07-02  Jonathan Coles   <[email protected]>
965    
966            Changed the singature of ClassGroupRange.__init__ and
967            ClassGroupRange.SetRange() so that the min/max values are
968            passed as a tuple. This makes a better calling scheme for
969            when a Range object is passed instead.
970    
971            * Thuban/Model/classgen.py: Fixed parameters to
972            ClassGroupRange constructor.
973    
974            * Thuban/Model/classification.py (ClassGroupRange.__init__):
975            Consolidate the min/max parameters into a single _range which
976            can either be a tuple or a Range object.
977            (ClassGroupRange.SetRange): Consolidate the min/max parameters
978            into a single _range which can either be a tuple or a Range object.
979    
980            * Thuban/Model/load.py (SessionLoader.start_clrange): Fix
981            call to ClassGroupRange constructor to use a tuple.
982    
983            * Thuban/Model/layer.py (Layer.SetClassification): Switch
984            the classification instance variable to the new class
985            before calling _set_layer otherwise subscribers to a
986            LAYER_CHANGED event will not see any difference.
987    
988            * test/test_classification.py: Fix tests of ClassGroupRange
989            so that they use the new signature.
990    
991            * test/test_load.py: Fix use of ClassGroupRange so that it
992            uses the new signature.
993    
994            * test/test_load_0_2.py: Fix use of ClassGroupRange so that it
995            uses the new signature.
996    
997            * test/test_save.py: Fix use of ClassGroupRange so that it
998            uses the new signature.

1001    2003-07-01  Jonathan Coles   <[email protected]>
1002    
1003            * Thuban/Model/classgen.py: Fixes RTbug #1972, 1971.
1004            Import used objects/class from color.
1005            (generate_singletons): We don't
1006            need the numGroups parameter anymore because we are using
1007            the new ramps with GetProperties().
1008            (generate_uniform_distribution): Use new ramp method
1009            GetProperties().
1010            (generate_quantiles, GenQuantiles0): Use new ramp method
1011            GetProperties().
1012            (CustomRamp.SetNumGroups): Removed. The ramps now map
1013            a value from 0 to 1 to class properties so the number
1014            of groups is not needed ahead of time.
1015            (CustomRamp.next): Removed. CustomRamp does not support
1016            interation anymore.
1017            (CustomRamp.GetProperties): Returns a ClassGroupProperties
1018            object based on the index value from 0 to 1 that is
1019            passed to it.
1020            (GreyRamp, RedRamp, GreenRamp, BlueRamp, GreenToRedRamp):
1021            Made into instances of Monochromatic class instread of
1022            deriving from it.
1023            (HotToCold.SetNumGroups): Removed. See CustomRamp.
1024            (HotToCold.next): Removed. See CustomRamp.
1025    
1026            * Thuban/Model/classification.py: Fixes RTbug #1973, 1971.
1027            (Classification.SetField, Classification.SetFieldType):
1028            Replaced with SetFieldInfo.
1029            (Classification.SetFieldInfo): New. Does a better job of
1030            what SetField and SetFieldType used to do by combining
1031            their function since they should really always be done
1032            at the same time.
1033            (Classification.SetLayer): Renamed to _set_layer.
1034            (Classification._set_layer): Should only be called from
1035            Layer's SetClassification. This does not cause a recursive
1036            call as SetLayer did because we know that Layer knows about
1037            the classification.
1038    
1039            * Thuban/Model/color.py: Fixes RTbug #1971.
1040            (_Transparent): Renamed from Transparent so it doesn't
1041            conflict with the module variable.
1042            (Transparent, Black): Renamed from Color.Transparent,
1043            Color.Black so they are not class variables.
1044    
1045            * Thuban/Model/layer.py: Fixes RTbug #1971, 1973.
1046            (Layer.Destroy): We don't need to call SetClassification
1047            anymore to clear out the back reference in the classifcation
1048            to the layer. It's better to set it to None using _set_layer,
1049            and we won't be creating another clas object too.
1050            (Layer.SetClassification): Classification._set_layer is not
1051            recursive so remove all the locking variables. Also clean
1052            up the code so that it remains unchanged if something fails.
1053    
1054            * Thuban/Model/load.py: Fixes RTbug #1971.
1055            (SessionLoader.start_classification): Call
1056            Classification.SetFieldInfo().
1057    
1058            * Thuban/Model/save.py: Removed import of Color which wasn't
1059            being used.
1060    
1061            * Thuban/UI/classgen.py: Fixes RTbug #1972.
1062            (ClassGenDialog.__init__): Color ramps are now instances
1063            already so we don't need to create any new objects.
1064            (ClassGenDialog.OnOK): Check for numGroups is no longer
1065            necessary because we never use it.
1066    
1067            * Thuban/UI/classifier.py: Fixes RTbug #1971.
1068            (Classifier.__BuildClassification, Classifier.__SetGridTable):
1069            Call Classification.SetFieldInfo() instead of SetFieldType.
1070    
1071            * Thuban/UI/renderer.py: Fixes RTbug #1971.
1072    
1073            * Thuban/UI/view.py: Fixes RTbug #1974, 1971.
1074            (MapCanvas.__init__): Subscribe to the idle time event. Set
1075            background color to white.
1076            (MapCanvas.OnPaint): Set a flag indicating that we should
1077            render the map during idle time. If we already have a bitmap
1078            just draw it now.
1079            (MapCanvas.OnIdle): New. Render the map only during idle time.
1080            This also fixes a problem with the busy cursor under gtk.
1081    
1082            * test/test_classgen.py (ClassGenTest.test_generate_singletons):
1083            Fix calls to generate_singletons because the signature changed.
1084    
1085            * test/test_classification.py: Fix color references and
1086            change calls to Classification.[SetField|SetFieldType] to
1087            SetFieldInfo.
1088    
1089            * test/test_load.py: Fix color references.
1090    
1091            * test/test_load_0_2.py: Fix color references.
1092    
1093            * test/test_save.py (SaveSessionTest.testClassifiedLayer):
1094            Change calls to Classification.[SetField|SetFieldType] to
1095            SetFieldInfo.

1119            sure to use the right internal names even when joining on field
1120            with the same names in both tables. Also, detect duplicate names
1121            in the joined table correctly.

1158            * Thuban/version.py: Added new 'versions' dictionary which
1159            contains the verions of various libraries which are checked
1160            when the module loads.
1161            (verify_versions): Check all version numbers and returns
1162            a list of errors.
1163    
1164            * Thuban/UI/classifier.py (Classifier.__EnableButtons):
1165            Reset the status of the buttons as the situation warrants,
1166            but in a better more reliable way by not relying on the
1167            current status to determine what needs to change.
1168    
1169            * Thuban/UI/main.py (wxCHECK_VERSION): Removed. Not needed.
1170            (verify_versions): Remove most of the code since it is
1171            now in Thuban.version.verify_versions.o
1172    
1173            * Thuban/UI/mainwindow.py (MainWindow.About): Call new
1174            About box in Thuban.UI.about.
1175    
1176            * extensions/thuban/gdalwarp.cpp (get_gdal_version): New.

1185    
1186    2003-06-25  Jonathan Coles   <[email protected]>
1187    
1188            * Thuban/UI/classifier.py (Classifier.EditSymbol): The parent
1189            of the SelectPropertiesDialog should be self so the window
1190            appears on top.
1191            (ClassGroupPropertiesCtrl.DoEdit): The parent
1192            of the SelectPropertiesDialog should be self so the window
1193            appears on top.
1194    
1195            * Thuban/UI/resource.py: Cleaned up how we determine file
1196            extensions.
1197            (GetImageResource): Return an wxImage from our Resources.
1198    
1199    2003-06-24  Jonathan Coles   <[email protected]>
1200    
1201            * Thuban/UI/renderer.py (ExportRenderer.render_legend):
1202            Check that a layer has a classification before trying
1203            to get it. Raster layers don't have classifications.
1204    
1205    2003-06-23  Jonathan Coles   <[email protected]>
1206            
1207            * setup.py: Add Resources/XML to resource list.

1212        
1213    2003-06-23  Jonathan Coles   <[email protected]>
1214    
1215            * MANIFEST.in: Update with Resources/XML
1216    
1217            * setup.py: Don't include Locale resources yet as we don't
1218            have any and it causes problems building the distribution
1219            for Windows. Update version to 0.8.0.
1220    
1221            * Doc/thuban.dtd: Removed since it is now in Resources/XML.
1222    
1223            * Thuban/UI/mainwindow.py: Add blank line at the end because
1224            file was not being read correctly building the Windows
1225            distribution.
1226    
1227    2003-06-23  Jonathan Coles   <[email protected]>
1228    
1229            * Thuban/UI/mainwindow.py (MainWindow.About): Fix text.
1230

1233    
1234    2003-06-23  Jonathan Coles   <[email protected]>
1235    
1236            * Thuban/UI/common.py (ThubanBeginBusyCursor): Call wxSafeYield
1237            to make sure that we don't create reentrant possibilities with
1238            wxYield.
1239    
1240            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxBeginBusyCursor()
1241            directly to avoid the wxSafeYield() call which generates an
1242            OnPaint event causing infinite recursion. Don't try to catch
1243            exception anymore. This was for before there were limits on map
1244            scaling.
1245    
1246    2003-06-23  Bernhard Herzog  <[email protected]>
1247    
1248            Bug fix for RT #1961:
1249    
1250            * Thuban/Model/load.py (SessionLoader.start_derivedshapesource):
1251            Register DerivedShapestores with the session
1252    
1253            * Thuban/Model/session.py (Session.Tables): Make sure each table
1254            is only listed once.
1255    
1256            * test/test_load.py (TestJoinedTable.test): Add check_format call.
1257            Update file contents to match the one written out.
1258    
1259    2003-06-20  Bernhard Herzog  <[email protected]>
1260    
1261            * test/xmlsupport.py (SaxEventLister.startElementNS)
1262            (SaxEventLister.endElementNS): Do not include the qname. Python
1263            2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
1264            is (presumably incorrectly) None, whereas it's a string with the
1265            element name in the later versions.
1266    
1267            * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
1268            (TestEventList.test_even_list_namespace): Update tests to reflect
1269            the new behaviour
1270            (TestEventList.test_even_list_id_normalization): Fix doc-string
1271    
1272    2003-06-20  Jonathan Coles   <[email protected]>
1273    
1274            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
1275            by deriving classes to determine if that layer supports shapes.
1276            (Layer): Override HasShapes and return true.
1277    
1278            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
1279            instead of a direct call to wx[Begin|End]CusyCursor().
1280            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
1281            table data.
1282    
1283            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
1284            New. Wrappers around the wxWindows functions that allow us to
1285            make additional calls such as wxYield which gives the native
1286            system a chance to update the cursor correctly.
1287    
1288            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
1289            instead of a direct call to wx[Begin|End]CusyCursor().
1290    
1291            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
1292            instead of a direct call to wx[Begin|End]CusyCursor().
1293            (MapCanvas.find_shape_at): Check if the current search layer
1294            support shapes, otherwise go on to the next layer.
1295    
1296            * test/test_layer.py: Add tests in each type of layer for
1297            HasClassification() and HasShapes()
1298    
1299    2003-06-20  Jonathan Coles   <[email protected]>
1300    
1301            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
1302            turning on the busy cursor to allow the system to change the
1303            cursor before we begin painting. This fixes a problem that
1304            was occuring only under GTK. Fixes RTbug #1840.
1305

1340            (SessionLoader.start_table, SessionLoader.end_table): Removed.
1341            They were never used in the old formats and aren't needed for the
1342            new.
1343    
1344            * Thuban/Model/session.py (Session.DataContainers): New method to
1345            return all "data containers", i.e. shapestores and tables

1348            (SaxEventLister.startElementNS, sax_eventlist): Add support to
1349            normalize IDs.

1387            * test/test_session.py
1388            (UnreferencedTablesTests.test_unreferenced_tables_with_joins):
1389            Use the cultural_landmark-point.dbf file for the store so that
1390            the table rows and shape count match.
1391    
1392    2003-06-20  Jonathan Coles   <[email protected]>
1393    
1394            * Thuban/Model/data.py (DerivedShapeStore.__init__): Raise
1395            an exception if the number of shapes is different from the
1396            number of rows in the table. Address RTbug #1933.

1434            sax_eventlist
1435    
1436    2003-06-20  Bernhard Herzog  <[email protected]>
1437

1439            Thuban are covered by this DTD
1440            (map): Fix content model for layers and raster layers. There can
1441            be any number or layers and raster layers in any order.
1442    
1443    2003-06-20  Jonathan Coles   <[email protected]>
1444    
1445            This is mainly about fixing RTbug #1949.
1446    
1447            * Thuban/Model/classification.py: Remove "from __future__"

1460    
1461            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
1462            scale adjust code since it is now done before calling

1465    
1466    2003-06-19  Bernhard Herzog  <[email protected]>
1467    
1468            Move version specific load tests to their own file.

1471            handle file format changes.
1472            (TestClassification.test): Update the docstring as this test is
1473            not about Thuban 0.2 anymore.
1474    
1475            * test/test_load_0_2.py: New file with the load tests for thuban
1476            files created with Thuban 0.2 and earlier.
1477    
1478    2003-06-19  Bernhard Herzog  <[email protected]>
1479    
1480            Add XML validation to some of the tests. Validation will only be
1481            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
1482            To make the DTD available to the test cases it's moved into
1483            Resources/XML
1484    
1485            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
1486            for versions up to and including 0.2. Two slight changes: added an
1487            encoding specification and fixed the comment which refered to
1488            GRASS, not Thuban
1489    
1490            * test/xmlsupport.py: New support module for tests involving XML.
1491            Currently there's a mix-in class for XML validation.
1492    
1493            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
1494    
1495            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
1496            so that we can validate the
1497            (SaveSessionTest.testEmptySession)
1498            (SaveSessionTest.testSingleLayer)
1499            (SaveSessionTest.testSingleLayer)
1500            (SaveSessionTest.testLayerProjection)
1501            (SaveSessionTest.testRasterLayer)
1502            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
1503    
1504            * test/runtests.py (main): Call print_additional_summary instead
1505            of print_garbage_information
1506    
1507            * test/support.py (resource_dir): New function to return the
1508            "Resource" subdirectory
1509            (print_additional_summary): New function to combine several
1510            summary functions
1511            (run_tests): Use print_additional_summary instead of calling
1512            print_garbage_information directly
1513    
1514    2003-06-19  Bernhard Herzog  <[email protected]>
1515

1517            the classification element.
1518            (projection): Add the "name" attribute
1519    
1520    2003-06-19  Frank Koormann   <[email protected]>
1521    
1522            MERGE from the greater-ms3 branch.
1523    
1524            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
1525            scale if projection is latlong to get better estimate.
1526    
1527            Fix problem of hidden properties dialog under windows after double
1528            click on layer tree:
1529            The tree control always gets an Expanded / Collapsed event after
1530            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
1531            raises the already displayed window.
1532    
1533            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
1534            raiseProperties initialized to prevent endless loops
1535            (LegendTree._OnItemActivated): Depending on self.raiseProperties
1536            simply raise the properties or open the dialog and issue a second
1537            event.
1538    
1539    2003-06-18  Jonathan Coles   <[email protected]>
1540    
1541            * setup.py: Fix a few problems that occured under Windows.
1542    
1543    2003-06-18  Jonathan Coles   <[email protected]>
1544    
1545            When Thuban loaded the map was redrawn twice because the
1546            legend was being opened after the mainwindow was created
1547            and not during its creation. This meant the map was drawn
1548            initially and then had to be redrawn when the legend
1549            caused the display to change. Now the legend is opened
1550            in the mainwindow constructor which resolves this issue.
1551    
1552            Also, although we were checking for the existence of
1553            gdal and gdalwarp modules, the gdalwarp extension was
1554            still being compiled (which may fail if the system doesn't
1555            have gdal installed). the build_ext command to setup.py
1556            now accepts the flags --with-gdal and --without-gdal.
1557            If --without-gdal is specified setup.py will try to
1558            use the gdal parameters specified by gdal-config. Under
1559            windows, those parameters have to be set in setup.py
1560            as with proj4 an wxWindows.
1561    
1562            * setup.py: Use a list instead of seperate variables for
1563            extension parameters so we can create a generic function
1564            that runs an appropriate *-config script.
1565            (run_cs_script): Renamed from run_wx_script and modified
1566            to accept a second argument which is a list of lists to
1567            be filled in by the values returned from running the command.
1568            (thuban_build_ext): New. Extends the build_ext command and
1569            provides the options --with-gdal/--without-gdal which then
1570            optionally includes the gdalwarp extension.
1571    
1572            * Thuban/Model/resource.py: First check if we can import
1573            the gdalwarp Thuban extension before checking for gdal.
1574            Also added some comments.
1575            
1576            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
1577            the map is None which may be the case if none has been loaded
1578            yet.
1579    
1580            * Thuban/UI/main.py (main): Remove call to ShowLegend.
1581    
1582            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
1583    
1584            * Thuban/UI/renderer.py: Check for gdal support before importing
1585            gdalwarp.
1586            (MapRenderer.render_map): Only try to optimize if we have gdal
1587            support otherwise nothing will get drawn.
1588    
1589            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
1590            during startup before a map has been created. Check if map is None
1591            before using it and do nothing if it is.
1592    
1593    2003-06-17  Jonathan Coles   <[email protected]>
1594    
1595            Fix the problem with raster layers under Windows that caused
1596            Thuban to crash. The view should respond to layer projection
1597            changed events to update the display. Changes to a projection
1598            should not cause the map to be set to full extent.
1599            
1600            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
1601            current_map_proj to remember the current map projection so that
1602            when the projection changes we know what the previous projection
1603            was.
1604            (MapCanvas.SetMap): Unsubscribe and subscribe to
1605            LAYER_PROJECTION_CHANGED events.
1606            (MapCanvas.projection_changed): Split into two methods that respond
1607            to map and layer projection changes.
1608            (MapCanvas.map_projection_changed): New. Takes the current view and
1609            projects it using the new projection. This does not cause the
1610            map to be redrawn at full extent.
1611            (MapCanvas.layer_projection_changed): New. Cause a redraw which
1612            will draw each layer in its new projection.
1613            
1614            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
1615            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
1616            under Windows.
1617            
1618            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
1619            to twice sizeof(void*) because there are two digits for each
1620            hex byte.
1621    
1622    2003-06-16  Bernhard Herzog  <[email protected]>
1623    
1624            Update to the layer interface: Direct access to the table,
1625            shapetable, shapefile and filename attributes is now actively
1626            deprecated by issuing deprecation warnings for all places where
1627            this happens.
1628    
1629            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
1630            to the instance variables table, shapetable, shapefile and
1631            filename via __getattr__ so that we can issue a deprecation
1632            warning.
1633            (Layer.SetShapeStore): Don't set the deprecated instance variables
1634            any more
1635            (Layer.SetShapeStore): Don't use deprecated layer instance
1636            variables
1637            (Layer.Destroy): No need to explicitly remove the instance
1638            variables any more
1639            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
1640            instance variables
1641    
1642            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
1643            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
1644            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
1645            use deprecated layer instance variables
1646    
1647            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
1648            deprecated layer instance variables
1649    
1650            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
1651            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
1652            instance variables
1653    
1654            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
1655            deprecated layer instance variables
1656    
1657            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
1658            deprecated layer instance variables
1659    
1660            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
1661            deprecated layer instance variables
1662    
1663            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
1664            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
1665            variables
1666    
1667            * test/runtests.py (main): Turn Thuban's deprecation warnings into
1668            errors so that they're cought by the tests
1669    
1670            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
1671            layer instance variables
1672    
1673    2003-06-16  Jonathan Coles   <[email protected]>
1674    
1675            Fix a problem under Windows whereby if the user double-clicks on a
1676            layer in the legend that tree item will expand or collapse as well
1677            as open the layer properties dialog. The state of the tree item
1678            should not be affected.
1679    
1680            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
1681            preventExpandCollapse and subscribe to expanding and collapsing
1682            events.
1683            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
1684            collapsing events and will veto the event if it has been triggered
1685            by the user double clicking on a layer.
1686            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
1687            that an expanding/collapsing event should be vetoed.
1688    
1689    2003-06-13  Bernhard Herzog  <[email protected]>
1690    
1691            * Thuban/UI/classifier.py (Classifier.OnClose)
1692            (Classifier.map_layers_removed)
1693            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
1694            in OnClose and not in map_layers_removed or
1695            layer_shapestore_replaced to make sure it always happens when the
1696            dialog is closed
1697    
1698    2003-06-13  Jonathan Coles   <[email protected]>
1699    
1700            This puts back a fix for Windows where a panel is needed so that
1701            the background of the table view appears correctly.
1702    
1703            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
1704            object that can be used by derived classes to place any
1705            controls (including the grid) onto.
1706            (QueryTableFrame.__init__): Use the panel as the parent window
1707            for all the controls. Reparent the grid so that the panel is
1708            the parent. Call UpdateStatusText() to correctly initialize
1709            the status bar.
1710    
1711    2003-06-13  Jonathan Coles   <[email protected]>
1712    
1713            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
1714            from wxFrame (as opposed to wxDialog like the other classes)
1715            but otherwise behaves like the other classes. This is needed
1716            for the TableView which isn't really a dialog and needs to
1717            have a status bar and control buttons.
1718    
1719            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
1720            instance variable to keep track of how many rows are selected.
1721            Subscribe once to the the events we are interested in.
1722            (ThubanGrid.OnRangeSelect): Only handle event if event handling
1723            hasn't been turned off.
1724            (ThubanGrid.OnSelectCell): Only handle event if event handling
1725            hasn't been turned off.
1726            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
1727            as an event listener (which changes the event handler stack)
1728            simply set an instance variable to False. This is checked in
1729            the event handlers.
1730            (ThubanGrid.GetNumberSelected): Return the number of currently
1731            selected rows.
1732            (TableFrame): Inherit from ThubanFrame so we can have a
1733            status bar and control buttons.
1734            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
1735            Explicitly set which items are selected in the operator choice and
1736            action choice so there is always a valid selection. Fixes RTbug #1941.
1737            Subscribe to grid cell selection events so we can update the
1738            status bar.
1739            (QueryTableFrame.UpdateStatusText): Update the status bar with
1740            how many rows are in the grid, how many columns, and how many
1741            rows are selected.
1742            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
1743            Call UpdateStatusText when cells are (de)selected.
1744            (QueryTableFrame.OnQuery): Use the string value in the value
1745            combo if either the selected item index is 0 or if the string
1746            cannot be found in the predefined list (this happens if the
1747            user changes the text). Fixes RTbug #1940.
1748            Only turn off the grid event listeners if there a query comes
1749            back with a none empty list of ids. in the case that the list
1750            is empty this causes a grid.ClearSelection() call to actually
1751            clear the grid selection which causes the selected items in
1752            the map to be deselected. Fixes RTbug #1939.
1753    
1754            * test/test_save.py (XMLWriterTest.Encode): Check return values.
1755            Fixes RTbug #1851.
1756    
1757    2003-06-13  Bernhard Herzog  <[email protected]>
1758    
1759            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
1760            self.selected_shape with the current selection to make sure the
1761            contents of the dialog are up to date when it's shown for the
1762            first time.
1763            The dialog used to work without this by luck. The recent fix to
1764            the connector module 'broke' a 'feature' the identify view was
1765            relying on, i.e that subscribing to a message in response to
1766            receiving a message of that type would mean that the new
1767            subscriber would also be called for the same message.
1768            
1769    2003-06-12  Jonathan Coles   <[email protected]>
1770    
1771            * extensions/thuban/gdalwarp.cpp: Removed debug printing as
1772            the image is rendered. Fixes RTbug #1937.
1773    
1774    2003-06-12  Jonathan Coles   <[email protected]>
1775    
1776            * Thuban/Lib/fileutil.py: As is done under Windows, create the
1777            user directory if it doesn't exist on a posix system.
1778            Fixes RTbug #1815.
1779    
1780            * Thuban/Model/resource.py (get_user_proj_files): Moved the
1781            called to get_application_dir here, so that the directory
1782            will only be called if this method is invoked.
1783    
1784            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
1785            the projfilepath if no projection is selected.
1786    
1787    2003-06-12  Jonathan Coles   <[email protected]>
1788    
1789            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
1790            the scalebar if the current map has no projection set.
1791    
1792            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
1793            projfilepath label to just the basename of the projection file
1794            rather than include the entire path.
1795    
1796            * Thuban/Model/resource.py: Fix missed proj functions that
1797            needed to be renamed.
1798    
1799    2003-06-12  Jonathan Coles   <[email protected]>
1800    
1801            * Thuban/Model/classification.py: Removed assert statements that
1802            tested if the variable was an instance of Color.
1803    
1804            * Thuban/Model/color.py (Color): Remove commented code that isn't
1805            used.
1806            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
1807            Fixes RTbug #1835.
1808            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
1809            Needed now that the class doesn't inherit from Color.
1810    
1811    2003-06-12  Jonathan Coles   <[email protected]>
1812    
1813            * test/test_save.py (XMLWriterTest.testEncode): Explicitly
1814            check unicode strings.
1815    
1816            * test/test_layer.py: Check for existence of gdal.
1817    
1818    2003-06-12  Jonathan Coles   <[email protected]>
1819        
1820            * Thuban/Model/xmlreader.py: New. Contains the XMLReader class
1821            that was in load.py
1822    
1823            * Thuban/Model/xmlwriter.py: New. Contains the XMLWriter class
1824            that was in save.py
1825    
1826    2003-06-12  Jonathan Coles   <[email protected]>
1827    
1828            This is largely a collection of bug fixes. We also handle the
1829            case where gdal is not on the system. The XMLReader and XMLWriter
1830            classes were moved into there own files to resolve some circular
1831            import references and because they shouldn't really be in the
1832            file that is dediciated to reading/writing session files since
1833            they are also used elsewhere.
1834    
1835            * Thuban/Model/classgen.py: Renamed functions to follow the
1836            function_names_with_underscores style. Fixes RTbug #1903.
1837            (calculate_quantiles): Raise ValueError if 'percents' is invalid.
1838    
1839            * Thuban/Model/layer.py: Import gdal only if it available.
1840            (RasterLayer): Handle the case where the gdal library is unavailable.
1841            Addresses RTbug #1877.
1842    
1843            * Thuban/Model/load.py (XMLReader): Moved into seperate file
1844            xmlreader.py.

1846    2003-06-12  Jonathan Coles   <[email protected]>
1847    
1848            This is largely a collection of bug fixes. We also handle the

1869            * Thuban/Model/resource.py: Renamed functions to following the
1870            function_names_with_underscores style.
1871            (has_gdal_support): New function that returns true if the gdal
1872            library is available. Addresses RTbug #1877.
1873    
1874            * Thuban/UI/application.py (ThubanApplication.OpenSession):
1875            Display a message box if the gdal library is not available, but
1876            only if there are any layers that would use it. Addresses RTbug #1877.
1877    
1878            * Thuban/UI/classgen.py: Use renamed projection resource functions.
1879            (GenUniformPanel.__CalcStepping): Fix a slight discrepency
1880            when using integers versus floats.
1881    
1882            * Thuban/UI/mainwindow.py (_has_gdal_support): New. Used to

1884            greyed out or not. Addresses RTbug #1877.
1885

1891            Addresses RTbug #1877.
1892    
1893            * test/test_classgen.py: Add tests for generate_singletons,
1894            generate_uniform_distribution, generate_quantiles. Fixes RTbug #1903.
1895            (test_calculate_quantiles): Fix some tests to catch the new
1896            ValueError that is raised.
1897    
1898            * test/test_proj.py: Use renamed projection resource functions.
1899

1939    
1940            * Thuban/Lib/connector.py (Connector.Issue): Iterate over a copy

1957    
1958            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
1959            parameter so we can subscribe to some of its messages
1960            (Classifier.__init__): Subscribe to the map's MAP_LAYERS_REMOVED
1961            and the layer's LAYER_SHAPESTORE_REPLACED

1982            (SetShapeStoreTests.test_set_shape_store_same_field_different_type):
1983            Add tests for the messages. This checks both the new

1997    2003-06-05  Frank Koormann  <[email protected]>
1998    
1999            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
2000            once on initialisation (Former implementation resulted in multiple
2001            entries for each projection).
2002            (ProjFrame.__FillAvailList): selectProj as second optional parameter,
2003            if set, select the projection found under the specified name. This
2004            overwrites any other selection estimate.
2005            Removed projchoice filling from this method.
2006            (ProjFrame._OnSave, ProjFrame._OnAddToList):
2007            Updated call of ProjFrame.__FillAvailList

2020    
2021            * Thuban/UI/application.py (ThubanApplication.read_startup_files):
2022            Guess location of .thuban directory from tempdir parent directory.
2023    
2024    2003-06-04  Bernhard Herzog  <[email protected]>
2025    
2026            Do not cache the values returned by the tree widget's
2027            GetFirstChild and GetNextChild methods because it led to lots of
2028            segfaults. The new way requires more brute force but is more
2029            reliable.
2030    
2031            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
2032            variable layer2id

2065    
2066            * test/test_base.py (SomeTitledObject): Derive from Modifiable
2067            instead of Publisher to reflect reality better and to accomodate
2068            the fact that SetTitle now calls changed instead of issue
2069    
2070    2003-06-02  Bernhard Herzog  <[email protected]>
2071    
2072            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource
2073            acquisition has to happen before the try in a try-finally.

2094    
2095            * Thuban/UI/legend.py (LegendTree.__init__): New instance variable
2096            changing_selection to indicate whether the LegendTree code itself
2097            is currently changing the selection
2098            (LegendTree.normalize_selection): New method to normalize the
2099            selection by selecting the layer item even if the user clicked on
2100            the classification.
2101            (LegendTree._OnSelChanged): normalize the selection. This works

2121    
2122            * Thuban/UI/classgen.py: Use classgen functions that were part
2123            of the ClassGenerator class. Put try/finally blocks around

2125            RTBug #1904.
2126    
2127            * Thuban/UI/classifier.py: Remove unused import of ClassGenerator.
2128    
2129            * Thuban/UI/legend.py: The legend was cleared and repopulated any

2139            (LegendTree.DeleteAllItems): Renamed from __DeleteAllItems so
2140            that we override the wxTreeCtrl method. Iterate over children
2141            and call __RemoveLayer.
2142            (LegendTree.__AddLayer): New. Add a new layer to the legend.
2143            (LegendTree.__RemoveLayer): Remove a layer from the legend.
2144            (LegendTree.DeleteChildren): New, overrides wxTreeCtrl method.

2158            simply center it on the display. Fixes RTBug #1849.
2159    
2160            * extensions/thuban/gdalwarp.cpp: Removed code that allowed gdalwarp
2161            to be compiled as a standalone app. Now the code can only be
2162            called from Python which simplifies the parameter passing.
2163            (ProjectRasterFile): Handle Python arguments. Remove code that
2164            checks for a destination dataset. Add more clean up code.
2165

2628    
2629            * Thuban/Model/transientdb.py (TransientTableBase.Dependencies)
2630            (TransientJoinedTable.Dependencies)
2631            (AutoTransientTable.SimpleQuery): New. Implement the dependencies
2632            interface
2633            (TransientJoinedTable.__init__): Keep tack of the original table
2634            objects in addition to the corresponding transient tables.

2665            Dependencies method.
2666    
2667            * test/test_session.py (TestSessionSimple.setUp)
2668            (TestSessionSimple.tearDown): New. Implement a better way to
2669            destroy the sessions.
2670            (TestSessionSimple.test_initial_state)
2671            (TestSessionSimple.test_add_table): Bind session to self.session
2672            so that it's destroyed by tearDown
2673            (TestSessionSimple.test_open_shapefile): New. Test for
2674            OpenShapefile and the object it returns
2675    
2676    2003-05-22  Bernhard Herzog  <[email protected]>
2677

2689            in reasonable order for keyboard navigation.
2690    
2691            * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
2692            (ProjFrame.__DoOnProjAvail): Determine position of current projection
2693            using the wxListBox.FindString() method. Still a problem (#1886)
2694    
2695            * Thuban/UI/classifier.py
2696            (Classifier.__init__, SelectPropertiesDialog.__init__)
2697    
2698            * Thuban/UI/classgen.py (ClassGenDialog.__init__,
2699            (ClassGenDialog.__DoOnGenTypeSelect): Moved initialization of the

2709    
2710            * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
2711            the text if not visible. The italic font sometimes exceeds the
2712            rendering area.
2713    
2714    2003-05-21  Jonathan Coles   <[email protected]>
2715    
2716            * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
2717            to OnClose so that Thuban closes correctly.
2718    
2719            * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
2720            DockFrame.OnClose, not DockFrame._OnClose.
2721    
2722    2003-05-21  Jonathan Coles   <[email protected]>
2723    
2724            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
2725            references to 'inf' and use new Range __init__ to pass floats
2726            directly rather than converting them to strings first.
2727            Fixes RTBug #1876.
2728    
2729            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
2730            Use new Range ___init__ to pass floats.
2731

2736            is immutable and has an __init__ which can accept floats.
2737    
2738            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
2739            into try block. AddLayer doesn't throw any exceptions anymore.

2749            print the error from GDAL.
2750    
2751            * Thuban/UI/tableview.py (TableGrid.__init__): Call
2752            ToggleEventListeners to turn on listening.

2755            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
2756            to suppress excessive messages when selecting many rows.
2757            Fixes RTBug #1880.
2758    
2759            * Thuban/UI/view.py: Added checks against if scale == 0. This
2760            is a serious problem that can occur when an image without
2761            geo data is loading and causes the map projection bounds to
2762            go to infinity. Right now, the solution is to simply try
2763            to recover.
2764    
2765            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
2766            to set the MFILEReceiver attributes even if the data is NULL.
2767    
2768            * extensions/thuban/gdalwarp.cpp: Improved the error handling
2769            and passed GDAL messages back up to the Python layer. Also
2770            tried to fix some memory leaks that were present in the original
2771            utility but didn't matter because the program aborted.
2772    
2773            * test/test_range.py: Copied over tests from SciParam. Removed
2774            tests against importing. Fixes RTBug #1867.
2775    
2776    2003-05-21  Bernhard Herzog  <[email protected]>
2777    
2778            * test/test_load.py: Remove unused imports and restructure the
2779            test code
2780            (LoadSessionTest): Split into one class for each test and turn

2786            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
2787            for the individual tests
2788    
2789            * test/support.py (FileLoadTestCase.filename): New base class for
2790            file loading tests
2791    
2792    2003-05-21  Jan-Oliver Wagner <[email protected]>
2793    
2794            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
2795            Mercator' to 'UTM Zone 32' as a more convenient example.
2796            Added 'Gauss Krueger Zone 6'.
2797    
2798            * Data/iceland_sample_raster.thuban: political polygon now
2799            filled transparent to have the raster image visible at once.
2800    
2801    2003-05-21  Frank Koormann  <[email protected]>
2802    
2803            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
2804            OnClose() to keep in sync with extensions. Internally Thuban
2805            still uses "underscored" names.
2806    
2807    2003-05-20  Jonathan Coles   <[email protected]>
2808    
2809            This puts back Raster layer support. These layers support projections
2810            through the GDAL library. Currently, the CVS version is being used.
2811            There are no Debian packages available although this may change soon.
2812            A GDAL driver was extended to support writing to memory rather to
2813            files.
2814    
2815            There is still some work that needs to be done, such as some error
2816            handling when loading invalid images or when there is a problem
2817            projecting the image. This putback simply checks in the majority
2818            of the work.
2819    
2820            * setup.py: Add gdalwarp library extension.
2821    
2822            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
2823            Defaults to False, but can be overridden by subclasses if they
2824            support classification.
2825            (RasterLayer): New. Defines a new layer that represents an
2826            image.
2827    
2828            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
2829            tag handler.
2830            (SessionLoader.start_layer): Encode the filename.
2831            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
2832            New. Supports reading a rasterlayer tag.
2833    
2834            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
2835    
2836            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
2837            get a string in Latin1. If we get such as string convert it to
2838            unicode first, otherwise leave if alone before encoding.
2839            (SessionSaver.write_layer): Add support for writing both Layers
2840            and RasterLayers.
2841    
2842            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
2843            The right argument may not be a string, it could also be a Column.
2844    
2845            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
2846            Make initial window size 600x400. Fixes RTBug #1872.
2847    
2848            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
2849            the dialog is constructed so that we can support layers that
2850            do not have classifications.
2851            (Classifier._OnTry): Only build a classification if the layer
2852            supports one.
2853    
2854            * Thuban/UI/legend.py: Change all checks that a layer is an
2855            instance of Layer into checks against BaseLayer.
2856            (LegendTree.__FillTreeLayer): Only add children to a branch if
2857            the layer supports classification.
2858    
2859            * Thuban/UI/mainwindow.py (MainWindow.NewSession,
2860            MainWindow.OpenSession): Don't proceed with an action if the
2861            user chooses Cancel when they are asked to save changes.
2862            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
2863            user to select an image file. Create a new RasterLayer and add
2864            it to the map.
2865    
2866            * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
2867            for rendering RasterLayer layers.
2868            (MapRenderer.draw_raster_layer): Actually method that calls
2869            the GDALWarp python wrapper and constructs an image from the
2870            data returned.
2871    
2872            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the
2873            Choices symbols to match those used in the table query method.
2874            Replace deprecated method calls on table with new method names.
2875    
2876            * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
2877            how small the scale can get. This still needs more testing.
2878    
2879            * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
2880            Provides a driver to output in .bmp format.
2881    
2882            * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h:
2883            New. Provides IO routines which write to memory, rather than a file.
2884    
2885            * extensions/thuban/gdalwarp.cpp: New, but basically a direct copy
2886            of the gdalwarp utility provided in GDAL. Added function calls
2887            that can be accessed from python.
2888    
2889            * Data/iceland_sample_raster.thuban: New. Sample file that uses
2890            a raster layer.

2893            layer image data.
2894    
2895            * Doc/thuban.dtd: Added rasterlayer attribute definition.
2896    
2897            * test/test_layer.py, test/test_load.py, test/test_save.py: Added
2898            tests associated with the raster layer code.
2899    
2900            * test/test_transientdb.py
2901            (TestTransientTable.test_auto_transient_table_query): Added a test
2902            for using a Column object as the "right" parameter to a query.
2903

2905    
2906            * Thuban/version.py (get_changelog_date):
2907            Catch exceptions if ChangeLog does not exist.
2908    
2909            * Thuban/UI/view.py (MapCanvas.Export): Bugfix
2910

2922    
2923            * Thuban/Model/save.py: Remove some unused imports including the
2924            __future__ import for nested_scopes as Thuban relies on Python 2.2
2925            now.
2926            (XMLWriter.encode): Remove the special case for a None argument.
2927            In the saver encode is always called with a string argument.
2928    
2929    2003-05-16  Bernhard Herzog  <[email protected]>
2930    
2931            * Thuban/UI/__init__.py: Remove the work-around for the locale bug
2932            in wxPython (at least when usinvg wxGTK) prior to 2.4. The symptom
2933            of the bug was that e.g. float("1.2") would fail. Thuban now
2934            requires 2.4.x.
2935            
2936    2003-05-16  Frank Koormann   <[email protected]>
2937    
2938            Printing enhancement and WMF export (under Win32)

2974            doesn't exist anymore.
2975    
2976            * Thuban/UI/classgen.py: Remove some unused imports
2977

2985            bounds of the generated classes.
2986    
2987            * Thuban/Model/range.py (Range.number_re): Now accepts floats that
2988            do not have a leading 0 (.5 is now accepted as well as 0.5).

3003            to table.UniqueValues() with calls that retrieve all the values
3004            from the table. This will need to be replaced by a method on table
3005            which can simply return the list (perhaps more efficiently).
3006    
3007    2003-05-12  Jonathan Coles   <[email protected]>
3008    
3009            The return value of ClassGenerator.CalculateQuantiles has changed.

3023    
3024    2003-05-12  Frank Koormann <[email protected]>
3025            
3026            * Thuban/Model/save.py (XMLWriter.encode()): Explicite call to unicode

3098            with correctly selecting the rows and issuing the right events.
3099            Be sure to call Skip() to allow the grid to do some of its own
3100            handling which allows the rows to actually be selected.
