9    
10    2003-08-11  Bernhard Herzog  <[email protected]>
11    
12            * test/support.py (FloatComparisonMixin.assertPointListEquals):
13            New. This method was used in various derived classes, but it's
14            better to have it here.
15    
16            * test/test_shapefilestore.py
17            (ShapefileStoreTests.assertPointListEquals): Removed. It's now in
18            FloatComparisonMixin

37    
38    2003-08-08  Jan-Oliver Wagner <[email protected]>
39    
40            * Thuban/UI/about.py (About.__init__): Reworked the hall of fame. Now
41            the list corresponds to the "About" web page.
42    
43    2003-08-08  Bernhard Herzog  <[email protected]>
44    
45            * Thuban/UI/projdialog.py (UTMProposeZoneDialog.dialogLayout):
46            Make sure translated strings are recognized as one string literal.
47

56    
57    2003-08-07  Bernhard Herzog  <[email protected]>
58    
59            * Thuban/Model/data.py (DerivedShapeStore.RawShapeFormat): New.
60            Simply delegates to the original shapestore.
61    
62            * test/test_derivedshapestore.py
63            (TestDerivedShapeStore.test_raw_format): New. Test case for
64            DerivedShapeStore.RawShapeFormat
65    
66    2003-08-07  Bernhard Herzog  <[email protected]>
67    
68            Add raw data interface to shape objects.
69    
70            * Thuban/Model/data.py (ShapefileShape, Shape): Rname the shape
71            class to ShapefileShape which now holds shapefile specific
72            information.
73            (ShapefileShape.compute_bbox): Simplified to not cache any
74            information. The way this method is used that shouldn't matter
75            performance wise.
76            (ShapefileShape.RawData): New. Return the shapeid which is the raw
77            data format for shapes from shapefiles.
78            (ShapefileStore.RawShapeFormat): New. Return the raw datatype used
79            in the shape objects returned by a shapestore. For a
80            ShapefileStore this is always RAW_SHAPEFILE.
81            (RAW_PYTHON, RAW_SHAPEFILE): Constants for the RawShapeFormat
82            method.
83    
84            * test/test_shapefilestore.py
85            (TestShapefileStore.test_raw_format): New test to test the raw
86            format feature of shapes.
87    
88            * Thuban/Model/layer.py: Remove the unused import of Shape from
89            data. It was only there for interface compatibility but it's not
90            used inside of Thuban and the generic Shape class has gone away.
91    
92            * Thuban/UI/renderer.py (MapRenderer.low_level_renderer): Check
93            the raw data format and only use an optimized version of its a
94            shapefile.
95    
96    2003-08-07  Bernhard Herzog  <[email protected]>
97    
98            * test/test_baserenderer.py (SimpleShape): Shape class for the
99            tests.
100            (SimpleShapeStore.Shape): Use SimpleShape instead of
101            Thuban.Model.data.Shape to make the tests independed of the coming
102            changes.
103    
104    2003-08-07  Bernhard Herzog  <[email protected]>
105    
106            * test/support.py (SkipTest, ThubanTestResult, ThubanTestRunner)
107            (ThubanTestProgram): New classes that extend the respective
108            classes from unittest. These new version support skipping tests
109            under certain expected conditions. In the Thuban test suite we
110            uses this for tests that require the optional gdal support.
111            (run_tests): Use ThubanTestProgram instead of the unittest.main()
112    
113            * test/runtests.py (main): Use the new ThubanTestRunner instead of
114            the normal one from unittest
115    
116            * test/test_layer.py (TestLayer.test_raster_layer): If this test
117            is not run because gdal support isn't available report this to the
118            runner.
119    
120            * test/test_baserenderer.py
121            (TestBaseRenderer.test_raster_no_projection): Do not run this test
122            if gdal support isn't available and report this to the runner.
123    
124    2003-08-06  Bernhard Herzog  <[email protected]>
125    
126            Rearrange the renderers a bit, partly in preparation for changes
127            required for the postgis merge, partly to make it more testable.
128            Also make the representation of coordinates in Shapes more
129            consistent.
130    
131            * Thuban/UI/renderer.py (MapRenderer): Most of the code/methods in
132            this class is now in BaseRenderer. This class is now practically
133            only a specialization of BaseRenderer for rendering to an actual
134            wx DC.
135            (ScreenRenderer.draw_shape_layer): Use self.low_level_renderer()
136            to get the shapetype specific rendering functions.
137    
138            * Thuban/UI/baserenderer.py: New file with the basic rendering
139            logic. The code in this file is completely independend of wx.
140            (BaseRenderer): Class with the basic rendering logic
141    
142            * test/test_baserenderer.py: New. Test cases for BaseRenderer
143    
144            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
145            error_on_redraw to guard agains endless loops and stack overflows
146            when there's a bug in the rendering code that raises exceptions.
147            (MapCanvas.OnIdle, MapCanvas._do_redraw): Split the actual
148            rendering into a separate method _do_redraw so that error handling
149            is a bit easier. When an exception occurs, set error_on_redraw to
150            true. When it's true on entry to OnIdle do nothing and return
151            immediately.
152    
153            * Thuban/Model/data.py (ShapefileStore.Shape): For consistency, a
154            Shape object will always have the coordinates as a list of list of
155            coordinate pairs (tuples).
156            (Shape.compute_bbox): Adapt to new representation.
157    
158            * Thuban/UI/viewport.py (ViewPort.find_shape_at)

162            * test/test_shapefilestore.py
163            (ShapefileStoreTests.assertFloatTuplesEqual)
164            (ShapefileStoreTests.assertPointListEquals): Rename to
165            assertPointListEquals and change purpose to checking equality of
166            the lists returned by Shape.Points().
167            (TestShapefileStoreArc.test_shape)
168            (TestShapefileStorePolygon.test_shape)
169            (TestShapefileStorePoint.test_shape): Use the new
170            assertPointListEquals instead of assertFloatTuplesEqual
171    
172            * test/test_layer.py (TestLayer.assertFloatTuplesEqual)
173            (TestLayer.assertPointListEquals): Rename to assertPointListEquals
174            and change purpose to checking equality of the lists returned by
175            Shape.Points().
176            (TestLayer.test_arc_layer, TestLayer.test_arc_layer)
177            (TestLayer.test_polygon_layer, TestLayer.test_point_layer)
178            (TestLayer.test_derived_store): Use the new assertPointListEquals
179            instead of assertFloatTuplesEqual
180    
181            * test/test_derivedshapestore.py
182            (TestDerivedShapeStore.assertFloatTuplesEqual)
183            (TestDerivedShapeStore.assertPointListEquals): Rename to
184            assertPointListEquals and change purpose to checking equality of
185            the lists returned by Shape.Points().
186            (TestDerivedShapeStore.test_shape): Use the new
187            assertPointListEquals instead of assertFloatTuplesEqual
188    
189    2003-08-06  Jan-Oliver Wagner <[email protected]>
190    
191            * Thuban/UI/projdialog.py (UTMPanel._OnPropose): Added test for
192            a bounding box. A dialog is raised in case, no bounding box
193            is found. This fixes bug #2043:
194            https://intevation.de/rt/webrt?serial_num=2043
195    
196    2003-08-05  Bernhard Herzog  <[email protected]>
197    
198            * Thuban/Model/color.py (Color.__repr__): Make the repr of a color
199            object look like a Color instantiation. Formerly it looked like a
200            tuple.
201    
202            * test/test_color.py (TestColor.test_repr)
203            (TestColor.test_equality, TestColor.test_inequality): New. test
204            some more apects of the Color class
205            (TestTransparent.test_repr, TestTransparent.test_hex)
206            (TestTransparent.test_equality): New. Test cases for the
207            Transparent object.
208    
209    2003-08-04  Jan-Oliver Wagner <[email protected]>
210    
211            * Doc/manual/thuban-manual.xml: a number of small improvements.
212            The resulting file is the version submitted for GREAT-ER II.
213    
214    2003-08-01  Bernhard Herzog  <[email protected]>
215    
216            * Thuban/UI/resource.py, Thuban/UI/projdialog.py,
217            Thuban/UI/join.py, Thuban/UI/classgen.py, Thuban/UI/about.py,
218            Thuban/Model/resource.py: Insert cvs keywords and doc-strings.
219    
220            * Thuban/UI/common.py: Insert cvs keywords and doc-strings.
221            (Color2wxColour, wxColour2Color, ThubanBeginBusyCursor)
222            (ThubanEndBusyCursor): Add doc-strings
223    
224    2003-08-01  Bernhard Herzog  <[email protected]>
225    
226            First step towards PostGIS integration. More abstraction by movin
227            more code from the layer to the shapestore. More methods of the
228            layer are now simply delegated to the equivalent method of the
229            shapestore. The SHAPETYPE_* constants are now in data not in
230            layer.
231    
232            * Thuban/Model/data.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
233            (SHAPETYPE_POINT, Shape): Move these constants and classes from
234            layer.py to data.py
235            (ShapefileStore.__init__): More Initialization for the new methods
236            and functionality.
237            (ShapefileStore.ShapeType, ShapefileStore.NumShapes)

239            (ShapefileStore.Shape): New methods that were formerly implemented
240            in the layer.
241            (DerivedShapeStore.Shape, DerivedShapeStore.ShapesInRegion)
242            (DerivedShapeStore.ShapeType, DerivedShapeStore.NumShapes)
243            (DerivedShapeStore.BoundingBox): New. DerivedShapeStore
244            equivalents of the new shape methods. These versions are simply
245            delegated to the original shapstore.
246    
247            * Thuban/Model/layer.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
248            (SHAPETYPE_POINT, Shape): Removed. They're now in data.py
249            (Layer.SetShapeStore): Removed the initializatin of instance
250            variables that were needed for the stuff that's now in
251            ShapefileStore
252            (Layer.BoundingBox, Layer.NumShapes, Layer.ShapeType)
253            (Layer.Shape, Layer.ShapesInRegion): Simply delegate to the
254            shapestore.
255    
256            * Thuban/UI/classifier.py, Thuban/UI/renderer.py,
257            Thuban/UI/viewport.py: Import the SHAPETYPE_* constants from data
258            instead of layer.
259    
260            * test/test_shapefilestore.py: New. Tests for ShapefileStore.
261    
262            * test/test_derivedshapestore.py: New. Tests for DerivedShapeStore.
263    
264            * test/test_layer.py: Import the SHAPETYPE_* constants from data
265            instead of layer.
266            (TestLayer.test_derived_store): Remove the test for the exception
267            when instantiating the DerivedShapeStore with an incompatible
268            table which is now in test_derivedshapestore.py. Add some more
269            tests of the layer methods to determine whether they work for a
270            DerivedShapeStore as well.
271    
272    2003-07-31  Jonathan Coles   <[email protected]>
273    
274            * Doc/manual/thuban-manual.xml: Fix the list of required packages
275            by just listing the name and where they can be found.
276    
277    2003-07-31  Frank Koormann   <[email protected]>
278    
279            * Doc/manual/thuban-manual.xml:
280            Changed the screenshot elements to figure.
281            Changed some variablelist elements to itemizedlist.
282            Added section on GDAL formats.
283    
284    2003-07-31  Jonathan Coles   <[email protected]>
285    
286            * Doc/manual/thuban-manual.xml: Added a few sentences about
287            the Fix Border Color option when generating classes.
288    
289    2003-07-30  Jonathan Coles   <[email protected]>
290    
291            * Thuban/Model/classgen.py: Add docstrings. Rename specific
292            Ramp instances to use lower_case_style.
293    
294            * Thuban/UI/classgen.py: Use renamed Ramp instances.
295            
296            * Thuban/UI/classifier.py: Add docstrings.
297    
298            * Thuban/UI/dock.py: Add docstrings.
299    
300            * test/test_classgen.py: Use renamed Ramp instances.
301    
302    2003-07-30  Bernhard Herzog  <[email protected]>
303    
304            * Thuban/Lib/connector.py (QueueingPublisher): Removed. This class
305            was never used in Thuban.
306    
307    2003-07-30  Bernhard Herzog  <[email protected]>
308    
309            * Thuban/UI/join.py (JoinDialog.__init__): Use the table's Title()
310            method directly instead of going through the transient_table
311            method. This faster because transient_table may force the copy of
312            a DBF file into the transient database and setting a table's title
313            doesnm't affect the title of the associated transient table, so
314            this fixes RT #2042
315    
316            * Thuban/UI/main.py (__version__): Don't import the already
317            removed show_exception_dialog.
318    
319    2003-07-29  Jonathan Coles   <[email protected]>
320    
321            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
322            Put back this method and remove the equivalent function since we
323            are setting the exception hook from within this class (OnInit).
324    
325    2003-07-29  Jonathan Coles   <[email protected]>
326    
327            * Doc/manual/images/5_2_custom_ramp.png,
328            Doc/manual/images/5_2_quantiles.png,
329            Doc/manual/images/5_2_uniform_dist.png,
330            Doc/manual/images/5_2_unique_values.png,
331            Doc/manual/images/8_int_error.png: New screen shots.
332    
333            * Doc/manual/thuban-manual.xml: Fixed typos and wording, clarified
334            some points, and added more screen shots.
335    
336    2003-07-29  Bernhard Herzog  <[email protected]>
337    
338            * Thuban/Model/data.py: Remove the now unused import of warnings
339    
340    2003-07-29  Bernhard Herzog  <[email protected]>
341    
342            * Thuban/Model/data.py (SimpleStore): Removed. This class has been
343            deprecated since before the 0.8 release and isn't used in Thuban
344            itself anymore.
345    
346            * Thuban/Model/transientdb.py: Remove some unnecessary imports
347    
348    2003-07-29  Jonathan Coles   <[email protected]>
349    
350            * Thuban/UI/application.py (ThubanApplication.OnInit): set the
351            python exception hook here so that we are sure to catch any
352            Thuban exception that happen during initialization.
353    
354            * Thuban/UI/main.py (main): Don't set the exception hook here,
355            it will get set in ThubanApplication.OnInit.
356    
357    2003-07-29  Jonathan Coles   <[email protected]>
358                                                                                
359            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
360            Removed and called it show_exception_dialog() so that the exception
361            handler can be set before the class is created.
362                                                                                
363            * Thuban/UI/main.py (main): Install the exception handler before
364            a ThubanApplication is created.
365

394    2003-07-28  Jonathan Coles   <[email protected]>
395    
396            * Doc/manual/thuban-manual.xml: More screenshots and more chapters.
397    
398            * Doc/manual/images/2_4_session_tree.png,
399            Doc/manual/images/3_5_legend.png, Doc/manual/images/3_rename_map.png,

407    
408    2003-07-24  Jonathan Coles   <[email protected]>
409    
410            * Doc/manual/thuban-manual.xml: Chapter on Projection Management.
411    
412    2003-07-24  Jonathan Coles   <[email protected]>
413    
414            * Doc/manual/thuban-manual.xml: Added EPS images and wrote
415            chapter on Layer Management.
416    
417            * Doc/manual/Makefile: New. Makefile to generate all formats for the
418            manual and images.
419    
420    2003-07-24  Bernhard Herzog  <[email protected]>
421    
422            * Thuban/Model/range.py, Thuban/version.py: Remove the #! line as
423            it annoys lintian which warns about these files not being
424            executable. The #1 isn't necessary here since if you absolutely
425            must execute them you can always say "python <filename>".
426    
427            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Remove
428            superfluous code to set brush and pen for point shapes
429    
430            * Thuban/UI/viewport.py: Remove commented out code that wouldn't
431            belong in viewport anyway
432    
433    2003-07-24  Frank Koormann   <[email protected]>
434    
435            * Doc/manual/thuban-manual.xml: Added section on table management.
436    
437    2003-07-24  Bernhard Herzog  <[email protected]>
438    
439            * test/runtests.py (main): Recognize the long "verbose" option
440            correctly.
441    
442    2003-07-22  Jonathan Coles   <[email protected]>
443    
444            * Doc/manual/thuban-manual.xml: Continue to write first revision
445            of the manual.
446    
447            * Thuban/UI/renderer.py (MapRenderer.render_map): Wrap method
448            with Begin/EndDrawing() calls to ensure we aren't doing to
449            many updates to the dc during rendering.
450            (ScreenRenderer.draw_shape_layer): self.draw_point_shape takes
451            a pen and brush argument so they need to be passed to the function.
452    
453            * Thuban/UI/viewport.py (ViewPort.calc_min_max_scales): New.
454            Calculates the minimum and maximum scale values. Factored out
455            of set_view_transform so that it could be used to zoom all the
456            way into a single point.
457            (ViewPort.set_view_transform): Call calc_min_max_scales().
458            (ViewPort.FitSelectedToWindow): Zoom to the maximum scale
459            if only a single point is selected.

481    
482    2003-07-18  Bernhard Herzog  <[email protected]>
483    
484            * Thuban/UI/messages.py (MAP_REPLACED): New message.
485    
486            * Thuban/UI/viewport.py (ViewPort.SetMap): Issue MAP_REPLACED
487            after the new map has been assigned
488    
489            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages):
490            Delegate MAP_REPLACED to the canvas too
491            (MainWindow.prepare_new_session): Removed. Thanks to the new
492            MAP_REPLACED message it's no longer needed
493            (MainWindow.OpenSession, MainWindow.NewSession):
494            prepare_new_session has been removed.
495    
496            * Thuban/UI/classifier.py (Classifier.__init__): Subscribe to
497            MAP_REPLACED so that we can close the dialog if a new map is set.
498            (Classifier.unsubscribe_messages): Unsubscribe from MAP_REPLACED
499            (Classifier.map_replaced): Handle MAP_REPLACED by closing the
500            dialog
501    
502            * test/test_viewport.py (SimpleViewPortTest)
503            (SimpleViewPortTest.test_default_size): Add doc-strings
504            (ViewPortTest.setUp): Bind map to self.map so we can use it in
505            tests. Subscribe to MAP_REPLACED messages too.
506            (ViewPortTest.tearDown): No need to explicitly unsubscribe
507            (ViewPortTest.test_set_map): New test for the SetMap method.
508    
509    2003-07-18  Bernhard Herzog  <[email protected]>
510    
511            * test/test_viewport.py (SimpleViewPortTest.test_default_size):
512            Move this test from ViewPortTest.setUp to this new separate test
513            case. setUp is not the place for the actual tests.
514            (ViewPortTest.test_inital_settings, ViewPortTest.setUp): Move some
515            more of the test from setUp to the new test test_inital_settings.
516            (ViewPortTest.test_win_to_proj, ViewPortTest.test_proj_to_win)
517            (ViewPortTest.test_proj_conv): Split test_proj_conv into
518            test_win_to_proj and test_proj_to_win and make the tests easier to
519            understand
520            (ViewPortTest.testFitRectToWindow, ViewPortTest.testZoomFactor)
521            (ViewPortTest.testZoomOutToRect, ViewPortTest.testTranslate)
522            (ViewPortTest.test_unprojected_rect_around_point)
523            (ViewPortTest.test_find_shape_at, ViewPortTest.testTools):
524            Reformat to increase readability.
525

527    
528            * Thuban/UI/view.py (MapCanvas.OnLeftDown): Capture the mouse.
529    
530    2003-07-18  Bernhard Herzog  <[email protected]>
531    
532            * test/runtests.py: The test suite can now be run without an X
533            connection. To make sure this remains true, remove the DISPLAY
534            environment variable so that an error occurs if the wxGTK is
535            imported accidentally
536    
537    2003-07-18  Bernhard Herzog  <[email protected]>
538    
539            * Thuban/UI/viewport.py: Remove unused imports
540    
541            * Thuban/UI/view.py: Remove unused imports
542    
543    2003-07-18  Bernhard Herzog  <[email protected]>
544    
545            * test/test_export.py Remove unused imports. The OutputTransform
546            function is now in viewport.py and is called output_transform
547            (TestScalebar.test_output_transform)
548            (TestScalebar.test_OutputTransform): Renamed to
549            test_output_transform and updated to use output_transform instead
550            of OutputTransform
551    
552            * Thuban/UI/view.py (OutputTransform): Moved to viewport.py and
553            renamed.
554            (MapCanvas.Export, MapPrintout.draw_on_dc): OutputTransform was
555            renamed to output_transform
556    
557            * Thuban/UI/viewport.py (OutputTransform, output_transform):
558            Rename to output_transform
559    
560    2003-07-18  Bernhard Herzog  <[email protected]>
561    
562            * Thuban/Model/layer.py (Layer.__init__): Rename
563            classificationField to classificatin_column and init it here so
564            that it can be used in SetClassificationColumn
565            (Layer.GetClassificationColumn, Layer.GetClassificationField):
566            Rename to GetClassificationColumn.
567            (Layer.SetClassificationColumn, Layer.SetClassificationField):
568            Rename to SetClassificationColumn and issue a LAYER_CHANGED
569            message if the column changes.
570            (Layer._classification_changed, Layer.ClassChanged): Rename to
571            _classification_changed. Update the callers.
572            (Layer.SetShapeStore): Further field->column renames.
573    
574            * Thuban/Model/load.py (SessionLoader.start_classification)
575            (SessionLoader.start_clpoint): Updates because of
576            field->column method name changes in the Layer class
577    
578            * Thuban/Model/save.py (SessionSaver.write_classification): Updates
579            because of field->column method name changes in the Layer class
580    
581            * Thuban/UI/classifier.py (Classifier.__init__)
582            (Classifier._OnTry, Classifier._OnRevert): Updates because of
583            field->column method name changes in the Layer class
584    
585            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Updates
586            because of field->column method name changes in the Layer class
587    
588            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Updates because
589            of field->column method name changes in the Layer class
590    
591            * test/test_save.py (SaveSessionTest.testClassifiedLayer)
592            (SaveSessionTest.testClassifiedLayer): Update because of
593            field->column method name changes in the Layer class
594    
595            * test/test_layer.py (SetShapeStoreTests.setUp)
596            (SetShapeStoreTests.test_sanity): Update because of field->column
597            method name changes in the Layer class
598            (TestLayerModification.setUp): Subscribe to LAYER_CHANGED as well
599            (TestLayerModification.test_sanity)
600            (TestLayerModification.test_initial_settings): remove unsued code
601            and rename to test_sanity.
602            (TestLayerModification.test_set_classification): New test for
603            SetClassification and SetClassificationField.
604    
605    2003-07-18  Bernhard Herzog  <[email protected]>
606    
607            * test/test_classgen.py (TestFixedRamp.test): Extend test to check
608            the non-fixed values as well. The old test would have accepted a
609            fixed ramp that only returnes the fixed properties
610    
611    2003-07-17  Jonathan Coles   <[email protected]>
612    
613            * Doc/manual/mainwindow.png, Doc/manual/mainwindow.xcf: Screen
614            shots for the manual. The XCF file is the source image and
615            has additional layers to support changes.
616    
617            * Doc/manual/thuban-manual.xml: Wrote an initial Introduction.
618    
619            * Thuban/UI/classifier.py (Classifier.__BuildClassification):
620            Return both the new class and the field name.
621    
622            * Thuban/UI/mainwindow.py (MainWindow.ToggleLegend): Don't
623            fit the map to the window as this changes any zoom level that
624            the user may have set.
625    
626    2003-07-16  Jonathan Coles   <[email protected]>
627    
628            * Thuban/Model/classgen.py (generate_singletons,
629            generate_uniform_distribution, generate_quantiles): Remove
630            fixes parameter, but maintain the same functionality by having
631            the calling function pass a FixedRamp object for the ramp.
632            (FixedRamp): New. Adapts a ramp to have fixed property values.
633    
634            * Thuban/Model/classification.py: Use new CLASS_CHANGED message.
635            (Classification): Inherit from Publisher.
636            (Classification.__init__): Remove the layer parameter.
637            Classifications no longer need to have a parent layer.
638            (Classification.GetField, Classification.GetFieldType,
639            Classification.SetFieldInfo): Removed. The field name is stored
640            in the layer, and the type can be retreived by calling
641            Layer.GetFieldType().
642            (Classification._set_layer, Classification.GetLayer): Removed.
643            Classifications no longer have a parent layer.
644    
645            * Thuban/Model/layer.py (Layer.Destroy): Unsubscribe from the
646            classification.
647            (Layer.SetShapeStore): Reset the classification first while
648            we still have the old shape store to work with.
649            (Layer.GetClassificationField, Layer.SetClassificationField):
650            New. Method for getting/setting the field to classify on.
651            (Layer.SetClassification): Simplified now that the layer
652            simply has to hold a reference to the classification and not
653            tell the classification who owns it.
654            Fixes RTbug #2023.
655    
656            * Thuban/Model/load.py (SessionLoader.start_classification):
657            Set the field name on the layer, not the classification.
658    
659            * Thuban/Model/messages.py: Add CLASS_CHANGED for when a
660            classification is modified.
661    
662            * Thuban/Model/save.py (SessionSaver.write_classification):
663            Get the field name and type from the layer.
664    
665            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Renamed
666            parameter records to rows and add docstring. Fixes RTbug #1997.
667    
668            * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Use a fixed
669            ramp when we need to fix certain values of a ramp rather than
670            using the old fixes parameter. Fixes RTbug #2024.
671    
672            * Thuban/UI/classifier.py (ClassGrid.CreateTable): Add fieldType
673            parameter.
674            (ClassTable.Reset): Add fieldType parameter and use it, rather
675            than asking the classification.
676            (Classifier.__init__): Remember the original class's field
677            and ask the layer for the field type, rather than the classification.
678            (Classifier.__SetGridTable): Retrieve the field and field type
679            for the table because they are not in the classification.
680            (Classifier._OnTry, Classifier._OnRevert): Set the classification
681            field on the layer in addition to the classification itself.
682    
683            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Get the
684            classification field from layer.
685    
686            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Get the
687            classification field from layer. Split up tests and remove
688            *-imports. Fixes RTbug #1992.
689    
690            * test/test_classgen.py (TestFixedRamp): Test for the FixedRamp class.
691    
692            * test/test_classification.py
693            (TestClassification.test_classification): Remove tests for methods
694            that no longer exist.
695    
696            * test/test_layer.py (SetShapeStoreTests.setUp): Classification
697            __init__ no longer has a field parameter, use SetClassificationField.
698            (SetShapeStoreTests.test_sanity): Use layer object to get class
699            field info.
700    
701            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Use
702            SetClassificationField on layer to set class field info.
703    
704            * test/test_viewport.py: Renamed from test/test_view.py.
705    
706    2003-07-16  Jan-Oliver Wagner <[email protected]>
707    
708            * Doc/manual/thuban-manual.xml: Added authors and an initial
709            coarse structure.
710    
711    2003-07-15  Bernhard Herzog  <[email protected]>
712    
713            * test/support.py (FloatComparisonMixin): This is a mix-in class
714            and therefore should not be derived from any other class.
715    
716            * test/test_range.py (RangeTest): FloatComparisonMixin is a
717            mix-in, so derive from TestCase as well.
718    
719    2003-07-15  Bernhard Herzog  <[email protected]>
720    
721            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Rework the
722            draw_func handling a bit to remove one layer of indirection. This
723            makes the renderer about 10% faster in the non-classifying case
724            and the code a bit cleaner
725            (MapRenderer.draw_point_shape): Add the pen and brush parameters
726            and set them in the dc. Now the draw_point_shape method and
727            wxproj's draw_polygon_shape function have basically the same
728            signature so that both can be directly used as draw_func
729    
730    2003-07-15  Bernhard Herzog  <[email protected]>
731    
732            * Thuban/Model/save.py (SessionSaver.write_classification): Encode
733            string values (in addition to the labels) as UTF 8
734    
735            * Thuban/Model/load.py (SessionLoader.start_clpoint): Decode the
736            values if the field type is string
737    
738            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Test
739            saving a session with non-ascii string classification values.
740    
741            * test/test_load.py (TestClassification.file_contents)
742            (TestClassification.test): Check for non-ascii values in string
743            classifications
744    
745    2003-07-14  Jonathan Coles   <[email protected]>
746    
747            * test/test_view.py: New. Tests for ViewPort.
748    
749    2003-07-14  Frank Koormann   <[email protected]>
750    
751            * Thuban/Model/load.py (SessionLoader.start_map): Encode map
752            title to latin1.  Fixes https://intevation.de/rt/webrt?serial_num=2013
753    
754            * test/test_load_0_8.py (TestUnicodeStrings): New, test load of
755            unicode strings from session file: session title, map title and
756            projection name.
757            
758    2003-07-10  Jonathan Coles   <[email protected]>
759    
760            * Thuban/UI/viewport.py (Tool.MouseUp): Should have called
761            drag_stop, not drag_move when the mouse is released.
762    
763    2003-07-10  Jonathan Coles   <[email protected]>
764    
765            The most important part of this is the seperation of view.py into
766            two pieces. viewport.py now has a class called ViewPort which
767            contains all the non-wx parts of view.py and can therefore be
768            tested. view.py contains only the wx-specific parts and is fairly
769            simple.
770    
771            * Thuban/UI/view.py: Stripped out all non-wx functionality. Fixes
772            RTTbug #1992.

872    
873            * Resources/XML/thuban-0.9.dtd: New. This will become the DTD for

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

949    
950    2003-07-02  Jonathan Coles   <[email protected]>
951    
952            * Thuban/Model/classgen.py (generate_singletons,
953            generate_uniform_distribution, generate_quantiles,
954            GenQuantiles0): Make sure maxValue isn't less than
955            one, otherwise we could divide by zero.
956    
957            * test/test_classgen.py (ClassGenTest.doClassRangeTest,
958            ClassGenTest.doClassSingleTest): Call doBoundsTest to
959            check the end classification groups against the
960            proper property values.
961            (ClassGenTest.doBoundsTest): New. Checks the first and
962            last classification groups to make sure their properties
963            are the correct upper and lower bounds for a color ramp.
964    
965    2003-07-02  Jonathan Coles   <[email protected]>
966    
967            * Thuban/Model/classgen.py (generate_singletons,
968            generate_uniform_distribution, generate_quantiles,
969            GenQuantiles0): The denominator was one to high when
970            calculating the index for the ramp causing the index
971            to never to reach one.
972    
973    2003-07-02  Jonathan Coles   <[email protected]>
974    
975            Changed the singature of ClassGroupRange.__init__ and
976            ClassGroupRange.SetRange() so that the min/max values are
977            passed as a tuple. This makes a better calling scheme for
978            when a Range object is passed instead.
979    
980            * Thuban/Model/classgen.py: Fixed parameters to
981            ClassGroupRange constructor.
982    
983            * Thuban/Model/classification.py (ClassGroupRange.__init__):
984            Consolidate the min/max parameters into a single _range which
985            can either be a tuple or a Range object.
986            (ClassGroupRange.SetRange): Consolidate the min/max parameters
987            into a single _range which can either be a tuple or a Range object.
988    
989            * Thuban/Model/load.py (SessionLoader.start_clrange): Fix
990            call to ClassGroupRange constructor to use a tuple.
991    
992            * Thuban/Model/layer.py (Layer.SetClassification): Switch
993            the classification instance variable to the new class
994            before calling _set_layer otherwise subscribers to a
995            LAYER_CHANGED event will not see any difference.
996    
997            * test/test_classification.py: Fix tests of ClassGroupRange
998            so that they use the new signature.
999    
1000            * test/test_load.py: Fix use of ClassGroupRange so that it
1001            uses the new signature.
1002    
1003            * test/test_load_0_2.py: Fix use of ClassGroupRange so that it
1004            uses the new signature.
1005    
1006            * test/test_save.py: Fix use of ClassGroupRange so that it
1007            uses the new signature.
1008    
1009    
1010    2003-07-01  Jonathan Coles   <[email protected]>
1011    
1012            * Thuban/Model/classgen.py: Fixes RTbug #1972, 1971.
1013            Import used objects/class from color.
1014            (generate_singletons): We don't
1015            need the numGroups parameter anymore because we are using
1016            the new ramps with GetProperties().
1017            (generate_uniform_distribution): Use new ramp method
1018            GetProperties().
1019            (generate_quantiles, GenQuantiles0): Use new ramp method
1020            GetProperties().
1021            (CustomRamp.SetNumGroups): Removed. The ramps now map
1022            a value from 0 to 1 to class properties so the number
1023            of groups is not needed ahead of time.
1024            (CustomRamp.next): Removed. CustomRamp does not support
1025            interation anymore.
1026            (CustomRamp.GetProperties): Returns a ClassGroupProperties
1027            object based on the index value from 0 to 1 that is
1028            passed to it.
1029            (GreyRamp, RedRamp, GreenRamp, BlueRamp, GreenToRedRamp):
1030            Made into instances of Monochromatic class instread of
1031            deriving from it.
1032            (HotToCold.SetNumGroups): Removed. See CustomRamp.
1033            (HotToCold.next): Removed. See CustomRamp.
1034    
1035            * Thuban/Model/classification.py: Fixes RTbug #1973, 1971.
1036            (Classification.SetField, Classification.SetFieldType):
1037            Replaced with SetFieldInfo.
1038            (Classification.SetFieldInfo): New. Does a better job of
1039            what SetField and SetFieldType used to do by combining
1040            their function since they should really always be done
1041            at the same time.
1042            (Classification.SetLayer): Renamed to _set_layer.
1043            (Classification._set_layer): Should only be called from
1044            Layer's SetClassification. This does not cause a recursive
1045            call as SetLayer did because we know that Layer knows about
1046            the classification.
1047    
1048            * Thuban/Model/color.py: Fixes RTbug #1971.
1049            (_Transparent): Renamed from Transparent so it doesn't
1050            conflict with the module variable.
1051            (Transparent, Black): Renamed from Color.Transparent,
1052            Color.Black so they are not class variables.
1053    
1054            * Thuban/Model/layer.py: Fixes RTbug #1971, 1973.
1055            (Layer.Destroy): We don't need to call SetClassification
1056            anymore to clear out the back reference in the classifcation
1057            to the layer. It's better to set it to None using _set_layer,
1058            and we won't be creating another clas object too.
1059            (Layer.SetClassification): Classification._set_layer is not
1060            recursive so remove all the locking variables. Also clean
1061            up the code so that it remains unchanged if something fails.
1062    
1063            * Thuban/Model/load.py: Fixes RTbug #1971.
1064            (SessionLoader.start_classification): Call
1065            Classification.SetFieldInfo().
1066    
1067            * Thuban/Model/save.py: Removed import of Color which wasn't
1068            being used.
1069    
1070            * Thuban/UI/classgen.py: Fixes RTbug #1972.
1071            (ClassGenDialog.__init__): Color ramps are now instances
1072            already so we don't need to create any new objects.
1073            (ClassGenDialog.OnOK): Check for numGroups is no longer
1074            necessary because we never use it.
1075    
1076            * Thuban/UI/classifier.py: Fixes RTbug #1971.
1077            (Classifier.__BuildClassification, Classifier.__SetGridTable):
1078            Call Classification.SetFieldInfo() instead of SetFieldType.
1079    
1080            * Thuban/UI/renderer.py: Fixes RTbug #1971.
1081    
1082            * Thuban/UI/view.py: Fixes RTbug #1974, 1971.
1083            (MapCanvas.__init__): Subscribe to the idle time event. Set
1084            background color to white.
1085            (MapCanvas.OnPaint): Set a flag indicating that we should
1086            render the map during idle time. If we already have a bitmap
1087            just draw it now.
1088            (MapCanvas.OnIdle): New. Render the map only during idle time.
1089            This also fixes a problem with the busy cursor under gtk.
1090    
1091            * test/test_classgen.py (ClassGenTest.test_generate_singletons):
1092            Fix calls to generate_singletons because the signature changed.
1093    
1094            * test/test_classification.py: Fix color references and
1095            change calls to Classification.[SetField|SetFieldType] to
1096            SetFieldInfo.
1097    
1098            * test/test_load.py: Fix color references.
1099    
1100            * test/test_load_0_2.py: Fix color references.
1101    
1102            * test/test_save.py (SaveSessionTest.testClassifiedLayer):
1103            Change calls to Classification.[SetField|SetFieldType] to
1104            SetFieldInfo.

1128            sure to use the right internal names even when joining on field
1129            with the same names in both tables. Also, detect duplicate names
1130            in the joined table correctly.

1165            library version information and credits.
1166    
1167            * Thuban/version.py: Added new 'versions' dictionary which
1168            contains the verions of various libraries which are checked
1169            when the module loads.
1170            (verify_versions): Check all version numbers and returns
1171            a list of errors.
1172    
1173            * Thuban/UI/classifier.py (Classifier.__EnableButtons):
1174            Reset the status of the buttons as the situation warrants,
1175            but in a better more reliable way by not relying on the
1176            current status to determine what needs to change.
1177    
1178            * Thuban/UI/main.py (wxCHECK_VERSION): Removed. Not needed.
1179            (verify_versions): Remove most of the code since it is
1180            now in Thuban.version.verify_versions.o
1181    
1182            * Thuban/UI/mainwindow.py (MainWindow.About): Call new
1183            About box in Thuban.UI.about.
1184    
1185            * extensions/thuban/gdalwarp.cpp (get_gdal_version): New.

1194    
1195    2003-06-25  Jonathan Coles   <[email protected]>
1196    
1197            * Thuban/UI/classifier.py (Classifier.EditSymbol): The parent
1198            of the SelectPropertiesDialog should be self so the window
1199            appears on top.
1200            (ClassGroupPropertiesCtrl.DoEdit): The parent
1201            of the SelectPropertiesDialog should be self so the window
1202            appears on top.
1203    
1204            * Thuban/UI/resource.py: Cleaned up how we determine file
1205            extensions.
1206            (GetImageResource): Return an wxImage from our Resources.
1207    
1208    2003-06-24  Jonathan Coles   <[email protected]>
1209    
1210            * Thuban/UI/renderer.py (ExportRenderer.render_legend):
1211            Check that a layer has a classification before trying
1212            to get it. Raster layers don't have classifications.
1213    
1214    2003-06-23  Jonathan Coles   <[email protected]>
1215            
1216            * setup.py: Add Resources/XML to resource list.
1217        
1218    2003-06-23  Jonathan Coles   <[email protected]>
1219    
1220            * setup.cfg: Fix copyright dates
1221        
1222    2003-06-23  Jonathan Coles   <[email protected]>
1223    
1224            * MANIFEST.in: Update with Resources/XML
1225    
1226            * setup.py: Don't include Locale resources yet as we don't
1227            have any and it causes problems building the distribution
1228            for Windows. Update version to 0.8.0.
1229    
1230            * Doc/thuban.dtd: Removed since it is now in Resources/XML.
1231    
1232            * Thuban/UI/mainwindow.py: Add blank line at the end because
1233            file was not being read correctly building the Windows
1234            distribution.
1235    
1236    2003-06-23  Jonathan Coles   <[email protected]>
1237    
1238            * Thuban/UI/mainwindow.py (MainWindow.About): Fix text.
1239

1242    
1243    2003-06-23  Jonathan Coles   <[email protected]>
1244    
1245            * Thuban/UI/common.py (ThubanBeginBusyCursor): Call wxSafeYield
1246            to make sure that we don't create reentrant possibilities with
1247            wxYield.
1248    
1249            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxBeginBusyCursor()
1250            directly to avoid the wxSafeYield() call which generates an
1251            OnPaint event causing infinite recursion. Don't try to catch
1252            exception anymore. This was for before there were limits on map
1253            scaling.
1254    
1255    2003-06-23  Bernhard Herzog  <[email protected]>
1256    
1257            Bug fix for RT #1961:
1258    
1259            * Thuban/Model/load.py (SessionLoader.start_derivedshapesource):
1260            Register DerivedShapestores with the session
1261    
1262            * Thuban/Model/session.py (Session.Tables): Make sure each table
1263            is only listed once.
1264    
1265            * test/test_load.py (TestJoinedTable.test): Add check_format call.
1266            Update file contents to match the one written out.
1267    
1268    2003-06-20  Bernhard Herzog  <[email protected]>
1269    
1270            * test/xmlsupport.py (SaxEventLister.startElementNS)
1271            (SaxEventLister.endElementNS): Do not include the qname. Python
1272            2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
1273            is (presumably incorrectly) None, whereas it's a string with the
1274            element name in the later versions.
1275    
1276            * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
1277            (TestEventList.test_even_list_namespace): Update tests to reflect
1278            the new behaviour
1279            (TestEventList.test_even_list_id_normalization): Fix doc-string
1280    
1281    2003-06-20  Jonathan Coles   <[email protected]>
1282    
1283            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
1284            by deriving classes to determine if that layer supports shapes.
1285            (Layer): Override HasShapes and return true.
1286    
1287            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
1288            instead of a direct call to wx[Begin|End]CusyCursor().
1289            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
1290            table data.
1291    
1292            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
1293            New. Wrappers around the wxWindows functions that allow us to
1294            make additional calls such as wxYield which gives the native
1295            system a chance to update the cursor correctly.
1296    
1297            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
1298            instead of a direct call to wx[Begin|End]CusyCursor().
1299    
1300            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
1301            instead of a direct call to wx[Begin|End]CusyCursor().
1302            (MapCanvas.find_shape_at): Check if the current search layer
1303            support shapes, otherwise go on to the next layer.
1304    
1305            * test/test_layer.py: Add tests in each type of layer for
1306            HasClassification() and HasShapes()
1307    
1308    2003-06-20  Jonathan Coles   <[email protected]>
1309    
1310            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
1311            turning on the busy cursor to allow the system to change the
1312            cursor before we begin painting. This fixes a problem that
1313            was occuring only under GTK. Fixes RTbug #1840.
1314

1351            new.
1352    
1353            * Thuban/Model/session.py (Session.DataContainers): New method to
1354            return all "data containers", i.e. shapestores and tables

1357            (SaxEventLister.startElementNS, sax_eventlist): Add support to
1358            normalize IDs.

1399            the table rows and shape count match.
1400    
1401    2003-06-20  Jonathan Coles   <[email protected]>
1402    
1403            * Thuban/Model/data.py (DerivedShapeStore.__init__): Raise
1404            an exception if the number of shapes is different from the

1455    
1456            * Thuban/Model/classification.py: Remove "from __future__"

1487    2003-06-19  Bernhard Herzog  <[email protected]>
1488    
1489            Add XML validation to some of the tests. Validation will only be
1490            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
1491            To make the DTD available to the test cases it's moved into
1492            Resources/XML
1493    
1494            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
1495            for versions up to and including 0.2. Two slight changes: added an
1496            encoding specification and fixed the comment which refered to
1497            GRASS, not Thuban
1498    
1499            * test/xmlsupport.py: New support module for tests involving XML.
1500            Currently there's a mix-in class for XML validation.

1502            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
1503    
1504            * test/test_save.py (SaveSessionTest): Derive from ValidationTest

1506            (SaveSessionTest.testEmptySession)
1507            (SaveSessionTest.testSingleLayer)
1508            (SaveSessionTest.testSingleLayer)

1510            (SaveSessionTest.testRasterLayer)
1511            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
1512    
1513            * test/runtests.py (main): Call print_additional_summary instead
1514            of print_garbage_information
1515    
1516            * test/support.py (resource_dir): New function to return the
1517            "Resource" subdirectory
1518            (print_additional_summary): New function to combine several
1519            summary functions
1520            (run_tests): Use print_additional_summary instead of calling
1521            print_garbage_information directly
1522

1530    
1531            MERGE from the greater-ms3 branch.
1532    
1533            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
1534            scale if projection is latlong to get better estimate.
1535    
1536            Fix problem of hidden properties dialog under windows after double
1537            click on layer tree:
1538            The tree control always gets an Expanded / Collapsed event after
1539            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
1540            raises the already displayed window.
1541    
1542            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
1543            raiseProperties initialized to prevent endless loops
1544            (LegendTree._OnItemActivated): Depending on self.raiseProperties
1545            simply raise the properties or open the dialog and issue a second
1546            event.
1547    
1548    2003-06-18  Jonathan Coles   <[email protected]>
1549    
1550            * setup.py: Fix a few problems that occured under Windows.
1551    
1552    2003-06-18  Jonathan Coles   <[email protected]>
1553    
1554            When Thuban loaded the map was redrawn twice because the
1555            legend was being opened after the mainwindow was created
1556            and not during its creation. This meant the map was drawn
1557            initially and then had to be redrawn when the legend
1558            caused the display to change. Now the legend is opened
1559            in the mainwindow constructor which resolves this issue.
1560    
1561            Also, although we were checking for the existence of
1562            gdal and gdalwarp modules, the gdalwarp extension was
1563            still being compiled (which may fail if the system doesn't
1564            have gdal installed). the build_ext command to setup.py
1565            now accepts the flags --with-gdal and --without-gdal.
1566            If --without-gdal is specified setup.py will try to
1567            use the gdal parameters specified by gdal-config. Under
1568            windows, those parameters have to be set in setup.py
1569            as with proj4 an wxWindows.
1570    
1571            * setup.py: Use a list instead of seperate variables for
1572            extension parameters so we can create a generic function
1573            that runs an appropriate *-config script.
1574            (run_cs_script): Renamed from run_wx_script and modified
1575            to accept a second argument which is a list of lists to
1576            be filled in by the values returned from running the command.
1577            (thuban_build_ext): New. Extends the build_ext command and
1578            provides the options --with-gdal/--without-gdal which then
1579            optionally includes the gdalwarp extension.
1580    
1581            * Thuban/Model/resource.py: First check if we can import
1582            the gdalwarp Thuban extension before checking for gdal.
1583            Also added some comments.
1584            
1585            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
1586            the map is None which may be the case if none has been loaded
1587            yet.
1588    
1589            * Thuban/UI/main.py (main): Remove call to ShowLegend.
1590    
1591            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
1592    
1593            * Thuban/UI/renderer.py: Check for gdal support before importing
1594            gdalwarp.
1595            (MapRenderer.render_map): Only try to optimize if we have gdal
1596            support otherwise nothing will get drawn.
1597    
1598            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
1599            during startup before a map has been created. Check if map is None
1600            before using it and do nothing if it is.
1601    
1602    2003-06-17  Jonathan Coles   <[email protected]>
1603    
1604            Fix the problem with raster layers under Windows that caused
1605            Thuban to crash. The view should respond to layer projection
1606            changed events to update the display. Changes to a projection
1607            should not cause the map to be set to full extent.
1608            
1609            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
1610            current_map_proj to remember the current map projection so that
1611            when the projection changes we know what the previous projection
1612            was.
1613            (MapCanvas.SetMap): Unsubscribe and subscribe to
1614            LAYER_PROJECTION_CHANGED events.
1615            (MapCanvas.projection_changed): Split into two methods that respond
1616            to map and layer projection changes.
1617            (MapCanvas.map_projection_changed): New. Takes the current view and
1618            projects it using the new projection. This does not cause the
1619            map to be redrawn at full extent.
1620            (MapCanvas.layer_projection_changed): New. Cause a redraw which
1621            will draw each layer in its new projection.
1622            
1623            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
1624            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
1625            under Windows.
1626            
1627            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
1628            to twice sizeof(void*) because there are two digits for each
1629            hex byte.
1630    
1631    2003-06-16  Bernhard Herzog  <[email protected]>
1632    
1633            Update to the layer interface: Direct access to the table,
1634            shapetable, shapefile and filename attributes is now actively
1635            deprecated by issuing deprecation warnings for all places where
1636            this happens.
1637    
1638            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
1639            to the instance variables table, shapetable, shapefile and
1640            filename via __getattr__ so that we can issue a deprecation
1641            warning.
1642            (Layer.SetShapeStore): Don't set the deprecated instance variables
1643            any more
1644            (Layer.SetShapeStore): Don't use deprecated layer instance
1645            variables
1646            (Layer.Destroy): No need to explicitly remove the instance
1647            variables any more
1648            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
1649            instance variables
1650    
1651            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
1652            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
1653            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
1654            use deprecated layer instance variables
1655    
1656            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
1657            deprecated layer instance variables
1658    
1659            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
1660            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
1661            instance variables
1662    
1663            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
1664            deprecated layer instance variables
1665    
1666            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
1667            deprecated layer instance variables
1668    
1669            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
1670            deprecated layer instance variables
1671    
1672            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
1673            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
1674            variables
1675    
1676            * test/runtests.py (main): Turn Thuban's deprecation warnings into
1677            errors so that they're cought by the tests
1678    
1679            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
1680            layer instance variables
1681    
1682    2003-06-16  Jonathan Coles   <[email protected]>
1683    
1684            Fix a problem under Windows whereby if the user double-clicks on a
1685            layer in the legend that tree item will expand or collapse as well
1686            as open the layer properties dialog. The state of the tree item
1687            should not be affected.
1688    
1689            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
1690            preventExpandCollapse and subscribe to expanding and collapsing
1691            events.
1692            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
1693            collapsing events and will veto the event if it has been triggered
1694            by the user double clicking on a layer.
1695            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
1696            that an expanding/collapsing event should be vetoed.
1697    
1698    2003-06-13  Bernhard Herzog  <[email protected]>
1699    
1700            * Thuban/UI/classifier.py (Classifier.OnClose)
1701            (Classifier.map_layers_removed)
1702            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
1703            in OnClose and not in map_layers_removed or
1704            layer_shapestore_replaced to make sure it always happens when the
1705            dialog is closed
1706    
1707    2003-06-13  Jonathan Coles   <[email protected]>
1708    
1709            This puts back a fix for Windows where a panel is needed so that
1710            the background of the table view appears correctly.
1711    
1712            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
1713            object that can be used by derived classes to place any
1714            controls (including the grid) onto.
1715            (QueryTableFrame.__init__): Use the panel as the parent window
1716            for all the controls. Reparent the grid so that the panel is
1717            the parent. Call UpdateStatusText() to correctly initialize
1718            the status bar.
1719    
1720    2003-06-13  Jonathan Coles   <[email protected]>
1721    
1722            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
1723            from wxFrame (as opposed to wxDialog like the other classes)
1724            but otherwise behaves like the other classes. This is needed
1725            for the TableView which isn't really a dialog and needs to
1726            have a status bar and control buttons.
1727    
1728            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
1729            instance variable to keep track of how many rows are selected.
1730            Subscribe once to the the events we are interested in.
1731            (ThubanGrid.OnRangeSelect): Only handle event if event handling
1732            hasn't been turned off.
1733            (ThubanGrid.OnSelectCell): Only handle event if event handling
1734            hasn't been turned off.
1735            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
1736            as an event listener (which changes the event handler stack)
1737            simply set an instance variable to False. This is checked in
1738            the event handlers.
1739            (ThubanGrid.GetNumberSelected): Return the number of currently
1740            selected rows.
1741            (TableFrame): Inherit from ThubanFrame so we can have a
1742            status bar and control buttons.
1743            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
1744            Explicitly set which items are selected in the operator choice and
1745            action choice so there is always a valid selection. Fixes RTbug #1941.
1746            Subscribe to grid cell selection events so we can update the
1747            status bar.
1748            (QueryTableFrame.UpdateStatusText): Update the status bar with
1749            how many rows are in the grid, how many columns, and how many
1750            rows are selected.
1751            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
1752            Call UpdateStatusText when cells are (de)selected.
1753            (QueryTableFrame.OnQuery): Use the string value in the value
1754            combo if either the selected item index is 0 or if the string
1755            cannot be found in the predefined list (this happens if the
1756            user changes the text). Fixes RTbug #1940.
1757            Only turn off the grid event listeners if there a query comes
1758            back with a none empty list of ids. in the case that the list
1759            is empty this causes a grid.ClearSelection() call to actually
1760            clear the grid selection which causes the selected items in
1761            the map to be deselected. Fixes RTbug #1939.
1762    
1763            * test/test_save.py (XMLWriterTest.Encode): Check return values.
1764            Fixes RTbug #1851.
1765    
1766    2003-06-13  Bernhard Herzog  <[email protected]>
1767    
1768            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
1769            self.selected_shape with the current selection to make sure the
1770            contents of the dialog are up to date when it's shown for the
1771            first time.
1772            The dialog used to work without this by luck. The recent fix to
1773            the connector module 'broke' a 'feature' the identify view was
1774            relying on, i.e that subscribing to a message in response to
1775            receiving a message of that type would mean that the new
1776            subscriber would also be called for the same message.
1777            
1778    2003-06-12  Jonathan Coles   <[email protected]>
1779    
1780            * extensions/thuban/gdalwarp.cpp: Removed debug printing as
1781            the image is rendered. Fixes RTbug #1937.
1782    
1783    2003-06-12  Jonathan Coles   <[email protected]>
1784    
1785            * Thuban/Lib/fileutil.py: As is done under Windows, create the
1786            user directory if it doesn't exist on a posix system.
1787            Fixes RTbug #1815.
1788    
1789            * Thuban/Model/resource.py (get_user_proj_files): Moved the
1790            called to get_application_dir here, so that the directory
1791            will only be called if this method is invoked.
1792    
1793            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
1794            the projfilepath if no projection is selected.
1795    
1796    2003-06-12  Jonathan Coles   <[email protected]>
1797    
1798            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
1799            the scalebar if the current map has no projection set.
1800    
1801            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
1802            projfilepath label to just the basename of the projection file
1803            rather than include the entire path.
1804    
1805            * Thuban/Model/resource.py: Fix missed proj functions that
1806            needed to be renamed.
1807    
1808    2003-06-12  Jonathan Coles   <[email protected]>
1809    
1810            * Thuban/Model/classification.py: Removed assert statements that
1811            tested if the variable was an instance of Color.
1812    
1813            * Thuban/Model/color.py (Color): Remove commented code that isn't
1814            used.
1815            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
1816            Fixes RTbug #1835.
1817            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
1818            Needed now that the class doesn't inherit from Color.
1819    
1820    2003-06-12  Jonathan Coles   <[email protected]>
1821    
1822            * test/test_save.py (XMLWriterTest.testEncode): Explicitly
1823            check unicode strings.
1824    
1825            * test/test_layer.py: Check for existence of gdal.
1826    
1827    2003-06-12  Jonathan Coles   <[email protected]>
1828        
1829            * Thuban/Model/xmlreader.py: New. Contains the XMLReader class
1830            that was in load.py
1831    
1832            * Thuban/Model/xmlwriter.py: New. Contains the XMLWriter class
1833            that was in save.py
1834    
1835    2003-06-12  Jonathan Coles   <[email protected]>
1836    
1837            This is largely a collection of bug fixes. We also handle the
1838            case where gdal is not on the system. The XMLReader and XMLWriter
1839            classes were moved into there own files to resolve some circular
1840            import references and because they shouldn't really be in the
1841            file that is dediciated to reading/writing session files since
1842            they are also used elsewhere.
1843    
1844            * Thuban/Model/classgen.py: Renamed functions to follow the
1845            function_names_with_underscores style. Fixes RTbug #1903.
1846            (calculate_quantiles): Raise ValueError if 'percents' is invalid.
1847    
1848            * Thuban/Model/layer.py: Import gdal only if it available.
1849            (RasterLayer): Handle the case where the gdal library is unavailable.
1850            Addresses RTbug #1877.
1851    
1852            * Thuban/Model/load.py (XMLReader): Moved into seperate file
1853            xmlreader.py.
1854    
1855    2003-06-12  Jonathan Coles   <[email protected]>
1856    
1857            This is largely a collection of bug fixes. We also handle the
1858            case where gdal is not on the system. The XMLReader and XMLWriter
1859            classes were moved into there own files to resolve some circular

1873            xmlreader.py.
1874    
1875            * Thuban/Model/save.py (escape, XMLWriter): Moved into seperate
1876            file xmlwriter.py.
1877    
1878            * Thuban/Model/resource.py: Renamed functions to following the
1879            function_names_with_underscores style.
1880            (has_gdal_support): New function that returns true if the gdal
1881            library is available. Addresses RTbug #1877.
1882    
1883            * Thuban/UI/application.py (ThubanApplication.OpenSession):
1884            Display a message box if the gdal library is not available, but
1885            only if there are any layers that would use it. Addresses RTbug #1877.
1886    
1887            * Thuban/UI/classgen.py: Use renamed projection resource functions.
1888            (GenUniformPanel.__CalcStepping): Fix a slight discrepency
1889            when using integers versus floats.
1890    
1891            * Thuban/UI/mainwindow.py (_has_gdal_support): New. Used to
1892            determine if the "Add Image Layer" menu option should be
1893            greyed out or not. Addresses RTbug #1877.
1894    
1895            * Thuban/UI/projdialog.py: Use renamed projection resource functions.
1896    
1897            * Thuban/UI/renderer.py (MapRenderer.render_map): Only try to
1898            optimize if a raster layer is visible. Fixes RTbug #1931.
1899            Only draw the raster layer if the gdal library is available.
1900            Addresses RTbug #1877.
1901    
1902            * test/test_classgen.py: Add tests for generate_singletons,
1903            generate_uniform_distribution, generate_quantiles. Fixes RTbug #1903.
1904            (test_calculate_quantiles): Fix some tests to catch the new
1905            ValueError that is raised.
1906

1967            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
1968            parameter so we can subscribe to some of its messages

2007    
2008            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
2009            once on initialisation (Former implementation resulted in multiple
2010            entries for each projection).
2011            (ProjFrame.__FillAvailList): selectProj as second optional parameter,
2012            if set, select the projection found under the specified name. This
2013            overwrites any other selection estimate.

2034    
2035            Do not cache the values returned by the tree widget's
2036            GetFirstChild and GetNextChild methods because it led to lots of

2038            reliable.
2039    
2040            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
2041            variable layer2id

2076            instead of Publisher to reflect reality better and to accomodate
2077            the fact that SetTitle now calls changed instead of issue
2078    
2079    2003-06-02  Bernhard Herzog  <[email protected]>
2080    
2081            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource

2091    
2092            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
2093            variables to None that have direct or indirect references to

2103    
2104            * Thuban/UI/legend.py (LegendTree.__init__): New instance variable

2130    
2131            * Thuban/UI/classgen.py: Use classgen functions that were part
2132            of the ClassGenerator class. Put try/finally blocks around

2168    
2169            * extensions/thuban/gdalwarp.cpp: Removed code that allowed gdalwarp
2170            to be compiled as a standalone app. Now the code can only be
2171            called from Python which simplifies the parameter passing.
2172            (ProjectRasterFile): Handle Python arguments. Remove code that
2173            checks for a destination dataset. Add more clean up code.
2174

2510    
2511    2003-05-22  Frank Koormann  <[email protected]>

2639            (TransientJoinedTable.Dependencies)
2640            (AutoTransientTable.SimpleQuery): New. Implement the dependencies
2641            interface

2674            Dependencies method.
2675    
2676            * test/test_session.py (TestSessionSimple.setUp)
2677            (TestSessionSimple.tearDown): New. Implement a better way to
2678            destroy the sessions.
2679            (TestSessionSimple.test_initial_state)
2680            (TestSessionSimple.test_add_table): Bind session to self.session
2681            so that it's destroyed by tearDown
2682            (TestSessionSimple.test_open_shapefile): New. Test for
2683            OpenShapefile and the object it returns
2684    
2685    2003-05-22  Bernhard Herzog  <[email protected]>
2686

2699    
2700            * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
2701            (ProjFrame.__DoOnProjAvail): Determine position of current projection
2702            using the wxListBox.FindString() method. Still a problem (#1886)
2703    
2704            * Thuban/UI/classifier.py
2705            (Classifier.__init__, SelectPropertiesDialog.__init__)
2706    
2707            * Thuban/UI/classgen.py (ClassGenDialog.__init__,
2708            (ClassGenDialog.__DoOnGenTypeSelect): Moved initialization of the

2718    
2719            * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
2720            the text if not visible. The italic font sometimes exceeds the
2721            rendering area.
2722    
2723    2003-05-21  Jonathan Coles   <[email protected]>
2724    
2725            * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
2726            to OnClose so that Thuban closes correctly.
2727    
2728            * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
2729            DockFrame.OnClose, not DockFrame._OnClose.
2730    
2731    2003-05-21  Jonathan Coles   <[email protected]>
2732    
2733            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
2734            references to 'inf' and use new Range __init__ to pass floats
2735            directly rather than converting them to strings first.
2736            Fixes RTBug #1876.
2737    
2738            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
2739            Use new Range ___init__ to pass floats.
2740    
2741            * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
2742            filename is a valid image file. Throw IOError otherwise.
2743

2745            is immutable and has an __init__ which can accept floats.
2746    
2747            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
2748            into try block. AddLayer doesn't throw any exceptions anymore.

2758            print the error from GDAL.
2759    
2760            * Thuban/UI/tableview.py (TableGrid.__init__): Call
2761            ToggleEventListeners to turn on listening.

2764            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
2765            to suppress excessive messages when selecting many rows.
2766            Fixes RTBug #1880.
2767    
2768            * Thuban/UI/view.py: Added checks against if scale == 0. This
2769            is a serious problem that can occur when an image without
2770            geo data is loading and causes the map projection bounds to
2771            go to infinity. Right now, the solution is to simply try
2772            to recover.
2773    
2774            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
2775            to set the MFILEReceiver attributes even if the data is NULL.
2776    
2777            * extensions/thuban/gdalwarp.cpp: Improved the error handling
2778            and passed GDAL messages back up to the Python layer. Also
2779            tried to fix some memory leaks that were present in the original
2780            utility but didn't matter because the program aborted.
2781    
2782            * test/test_range.py: Copied over tests from SciParam. Removed
2783            tests against importing. Fixes RTBug #1867.
2784    
2785    2003-05-21  Bernhard Herzog  <[email protected]>
2786    
2787            * test/test_load.py: Remove unused imports and restructure the
2788            test code
2789            (LoadSessionTest): Split into one class for each test and turn

2795            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
2796            for the individual tests
2797    
2798            * test/support.py (FileLoadTestCase.filename): New base class for
2799            file loading tests
2800    
2801    2003-05-21  Jan-Oliver Wagner <[email protected]>
2802    
2803            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
2804            Mercator' to 'UTM Zone 32' as a more convenient example.
2805            Added 'Gauss Krueger Zone 6'.
2806    
2807            * Data/iceland_sample_raster.thuban: political polygon now
2808            filled transparent to have the raster image visible at once.
2809    
2810    2003-05-21  Frank Koormann  <[email protected]>
2811    
2812            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
2813            OnClose() to keep in sync with extensions. Internally Thuban
2814            still uses "underscored" names.
2815    
2816    2003-05-20  Jonathan Coles   <[email protected]>
2817    
2818            This puts back Raster layer support. These layers support projections
2819            through the GDAL library. Currently, the CVS version is being used.
2820            There are no Debian packages available although this may change soon.
2821            A GDAL driver was extended to support writing to memory rather to
2822            files.
2823    
2824            There is still some work that needs to be done, such as some error
2825            handling when loading invalid images or when there is a problem
2826            projecting the image. This putback simply checks in the majority
2827            of the work.
2828    
2829            * setup.py: Add gdalwarp library extension.
2830    
2831            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
2832            Defaults to False, but can be overridden by subclasses if they
2833            support classification.
2834            (RasterLayer): New. Defines a new layer that represents an
2835            image.
2836    
2837            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
2838            tag handler.
2839            (SessionLoader.start_layer): Encode the filename.
2840            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
2841            New. Supports reading a rasterlayer tag.
2842    
2843            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
2844    
2845            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
2846            get a string in Latin1. If we get such as string convert it to
2847            unicode first, otherwise leave if alone before encoding.
2848            (SessionSaver.write_layer): Add support for writing both Layers
2849            and RasterLayers.
2850    
2851            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
2852            The right argument may not be a string, it could also be a Column.
2853    
2854            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
2855            Make initial window size 600x400. Fixes RTBug #1872.
2856    
2857            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
2858            the dialog is constructed so that we can support layers that
2859            do not have classifications.
2860            (Classifier._OnTry): Only build a classification if the layer
2861            supports one.
2862    
2863            * Thuban/UI/legend.py: Change all checks that a layer is an
2864            instance of Layer into checks against BaseLayer.
2865            (LegendTree.__FillTreeLayer): Only add children to a branch if
2866            the layer supports classification.
2867    
2868            * Thuban/UI/mainwindow.py (MainWindow.NewSession,
2869            MainWindow.OpenSession): Don't proceed with an action if the
2870            user chooses Cancel when they are asked to save changes.
2871            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
2872            user to select an image file. Create a new RasterLayer and add
2873            it to the map.
2874    
2875            * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
2876            for rendering RasterLayer layers.
2877            (MapRenderer.draw_raster_layer): Actually method that calls
2878            the GDALWarp python wrapper and constructs an image from the
2879            data returned.
2880    
2881            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the
2882            Choices symbols to match those used in the table query method.
2883            Replace deprecated method calls on table with new method names.
2884    
2885            * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
2886            how small the scale can get. This still needs more testing.
2887    
2888            * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
2889            Provides a driver to output in .bmp format.
2890    
2891            * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h:
2892            New. Provides IO routines which write to memory, rather than a file.
2893    
2894            * extensions/thuban/gdalwarp.cpp: New, but basically a direct copy
2895            of the gdalwarp utility provided in GDAL. Added function calls
2896            that can be accessed from python.
2897    
2898            * Data/iceland_sample_raster.thuban: New. Sample file that uses
2899            a raster layer.

2902            layer image data.
2903    
2904            * Doc/thuban.dtd: Added rasterlayer attribute definition.
2905    
2906            * test/test_layer.py, test/test_load.py, test/test_save.py: Added
2907            tests associated with the raster layer code.
2908    
2909            * test/test_transientdb.py
2910            (TestTransientTable.test_auto_transient_table_query): Added a test
2911            for using a Column object as the "right" parameter to a query.
2912

2914    
2915            * Thuban/version.py (get_changelog_date):
2916            Catch exceptions if ChangeLog does not exist.
2917    
2918            * Thuban/UI/view.py (MapCanvas.Export): Bugfix
2919    
2920    2003-05-19  Frank Koormann  <[email protected]>

2931    
2932            * Thuban/Model/save.py: Remove some unused imports including the
2933            __future__ import for nested_scopes as Thuban relies on Python 2.2
2934            now.
2935            (XMLWriter.encode): Remove the special case for a None argument.
2936            In the saver encode is always called with a string argument.
2937    
2938    2003-05-16  Bernhard Herzog  <[email protected]>
2939    
2940            * Thuban/UI/__init__.py: Remove the work-around for the locale bug
2941            in wxPython (at least when usinvg wxGTK) prior to 2.4. The symptom
2942            of the bug was that e.g. float("1.2") would fail. Thuban now
2943            requires 2.4.x.
2944            
2945    2003-05-16  Frank Koormann   <[email protected]>
2946    
2947            Printing enhancement and WMF export (under Win32)
2948    
2949            * Thuban/UI/renderer.py (ExportRenderer): New, derived from

2968            * Thuban/Model/scalebar.py (roundInterval): round long instead of int
2969    
2970            * Thuban/UI/legend.py (ScalebarBitmap.__SetScale):
2971            Update to extended scalebar.DrawScalebar header.

2983            doesn't exist anymore.
2984    
2985            * Thuban/UI/classgen.py: Remove some unused imports
2986

2994            bounds of the generated classes.
2995    
2996            * Thuban/Model/range.py (Range.number_re): Now accepts floats that
2997            do not have a leading 0 (.5 is now accepted as well as 0.5).

3011            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Replace call
3012            to table.UniqueValues() with calls that retrieve all the values
3013            from the table. This will need to be replaced by a method on table
3014            which can simply return the list (perhaps more efficiently).
3015    
3016    2003-05-12  Jonathan Coles   <[email protected]>
3017    
3018            The return value of ClassGenerator.CalculateQuantiles has changed.
3019            Refer to the documentation for details.

3032    
3033    2003-05-12  Frank Koormann <[email protected]>
3034            
3035            * Thuban/Model/save.py (XMLWriter.encode()): Explicite call to unicode

3424            when we ask the table for the maximum/minimum values of a field
3425            which could take a very long time.
3426    
3427            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange the
3428            order that the controls are created so that tabbing works correctly.
3429            (SelectPropertiesDialog.__init__): Rearrange the order that the
3430            controls are created so that tabbing works correctly.
3431    
3432            * Thuban/UI/dialogs.py: Copied NonModalDialog box and changed it
3433            to derive from a wxDialog but behave like the original implementation
3434            which was derived from a wxFrame. wxDialog provides useful key
3435            handling functionality like ESC calling OnCancel and ENTER calling
3436            OnOK which is lost with wxFrame.
3437    
3438            * Thuban/UI/mainwindow.py: Add "..." to menu items that will open
3439            new dialogs.
3440    
3441            * Thuban/UI/projdialog.py (ProjFrame.__init__): Rearrange the
3442            order that the controls are created so that tabbing works correctly.
3443            (ProjFrame.OnApply): Renamed from _OnTry() to use wxDialog behaviour.
3444            (ProjFrame.OnOK): Renamed from _OnOK() to use wxDialog behaviour.
3445            (ProjFrame.OnCancel): Renamed from _OnClose() to use wxDialog behaviour.
3446            (ProjPanel.__init__): Add "Airy" to the list of ellipsoids so we
3447            can provide the "UK National Grid" as a default projection.
3448            (UTMPanel.__init__): Rearrange the order that the controls are
3449            created so that tabbing works correctly.

3451    2003-05-05  Bernhard Herzog  <[email protected]>
3452    
3453            * extensions/thuban/wxproj.cpp: Fix some of the comments.
3454            (project_point): If a map projection but no layer projection is
3455            given, convert degrees to radians before applying the map
3456            projection.
3457    
3458            * Thuban/UI/tableview.py (TableGrid.disallow_messages)
3459            (TableGrid.allow_messages): New methods to make it possible to
3460            inhibit message sending.
3461            (TableGrid.issue): Only send the message if not inhibited.
3462            (LayerTableGrid.select_shape): Use the new methods to make sure
3463            that no ROW_SELECTED message is sent while we're updating the
3464            selected rows to match the selected shapes.
3465    
3466    2003-05-02  Jan-Oliver Wagner <[email protected]>
3467    
3468            Implementation of MemoryTable.
3469    
3470            * Thuban/Model/table.py (MemoryTable): New. Quite simple table
3471            implementation that operates on a list of tuples. All of the data
3472            are kept in the memory.
3473    
3474            * test/test_table.py (MemoryTableTest): New.
3475    
3476            * test/test_transientdb.py (SimpleTable): Removed.
3477            (TestTransientTable.test_transient_joined_table,
3478            (TestTransientTable.test_transient_table_read_twice): Replaced
3479            SimpleTable by MemoryTable.
3480    
3481    2003-04-30  Jonathan Coles   <[email protected]>
3482    
3483            * Data/iceland_sample.thuban: Now contains correct projections
3484            for each of the layers.
3485    
3486            * Resources/Projections/defaults.proj: Geographic projection
3487            contains unit conversion parameter.
3488    
3489    2003-04-30  Jonathan Coles   <[email protected]>
3490    
3491            The most important part of this putback is the projection changes.
3492            It should now be possible to specify the projection that a layer
3493            is in and then specify a different projection for the map. The
3494            projection dialog has an extra parameter for a geographic projection
3495            which lets the user select if the input is in degrees or radians.
3496    
3497            * Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring
3498            to say that the parameter is a tuple of unprojected
3499            points (which is what the callers to this method were assuming).
3500            Also, since the points are unprojected we need to projected them.
3501    
3502            * Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp,
3503            LegendTree.MoveCurrentItemDown): If the layer or any of the layer's
3504            groups are selected, move the layer up/down. Fixes RTbug #1833.
3505    
3506            * Thuban/UI/mainwindow.py: Move menu item map_rename up.
3507    
3508            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing
3509            parameter in call to SetClientData.
3510            (GeoPanel): Add support for selecting the units that the
3511            source data is in (Radians or Degrees).
3512    
3513            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize
3514            the rendering loop by reducing the number of if's, removing the
3515            unnecessary try/except block, and checking if the old group
3516            is the same as the new one (which happens a lot if there is
3517            no classification, or lots of shapes are in the same group).
3518    
3519            * Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block
3520            around the redraw routine to try to catch problems that the user
3521            may create by selecting invalid projections for the data set and
3522            map. Clears the display if there are any problems and prints the
3523            error.
3524            (MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled
3525            rectangle.
3526    
3527            * extensions/thuban/wxproj.cpp (project_point): First invert the
3528            supplied point (which should be in projected coordinates) using
3529            the layer's projection and then project the point using the
3530            map's projection.
3531            (project_points): Use project_point() to project each point.
3532    
3533    2003-04-30  Jan-Oliver Wagner <[email protected]>
3534    
3535            * Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug:
3536            don't set the Classification to None if the classfication field
3537            is None (ie only a DEFAULT).
3538    
3539    2003-04-30  Bernhard Herzog  <[email protected]>
3540    
3541            * Thuban/UI/view.py: Fix some typos.
3542    
3543            * Thuban/UI/mainwindow.py (MainWindow.identify_view_on_demand): Do
3544            not pop up the dialog if the selection becomes empty (this could
3545            happen if e.g. a new selection is opened while the identify tool
3546            is active and dialog had been closed)
3547    
3548    2003-04-30  Bernhard Herzog  <[email protected]>
3549    
3550            * Thuban/Model/transientdb.py (TransientTableBase.__init__): New
3551            instance variable read_record_last_result
3552            (TransientTableBase.read_record): Make sure reading the same
3553            record twice works. The implementation uses the new instance
3554            variable read_record_last_result
3555    
3556            * test/test_transientdb.py
3557            (TestTransientTable.test_transient_table_read_twice): New test
3558            case for the above bug-fix.
3559    
3560    2003-04-29  Jonathan Coles   <[email protected]>
3561    
3562            * Thuban/common.py: Removed. No longer needed Str2Num. RTbug #1832.
3563    
3564            * Thuban/UI/classgen.py: Remove all uses of Str2Num.
3565    
3566            * Thuban/UI/classifier.py: Remove all uses of Str2Num.
3567            (ClassTable.SetValueAsCustom): Rename keyword argument in
3568            ClassGroup* constructors to match argument name.
3569    
3570    2003-04-29  Bernhard Herzog  <[email protected]>
3571    
3572            * Thuban/Model/session.py (Session.Destroy): Explicitly close the
3573            transient DB if it exists to make sure it doesn't leave a journal
3574            file in the temp directory.
3575    
3576            * Thuban/Model/transientdb.py (TransientDatabase.close): Set
3577            self.conn to None after closing the connection to make sure it's
3578            not closed twice
3579    
3580  2003-04-29  Jonathan Coles   <[email protected]>  2003-04-29  Jonathan Coles   <[email protected]>
3581    
3582          Add a visible parameter in the layer XML tag. The default value is          Add a visible parameter in the layer XML tag. The default value is
3583          "true". If anything other than "false" is specified we also assume          "true". If anything other than "false" is specified we also assume
3584          "true".          "true". Addresses RTbug #1025.
3585    
3586          * Doc/thuban.dtd: Add visible parameter to a layer.          * Doc/thuban.dtd: Add visible parameter to a layer.
