1    2003-07-24  Bernhard Herzog  <[email protected]>
2    
3            * test/runtests.py (main): Recognize the long "verbose" option
4            correctly.
5    
6    2003-07-22  Jonathan Coles   <[email protected]>
7    
8            * Doc/manual/thuban-manual.xml: Continue to write first revision
9            of the manual.
10    
11            * Thuban/UI/renderer.py (MapRenderer.render_map): Wrap method
12            with Begin/EndDrawing() calls to ensure we aren't doing to
13            many updates to the dc during rendering.
14            (ScreenRenderer.draw_shape_layer): self.draw_point_shape takes
15            a pen and brush argument so they need to be passed to the function.
16    
17            * Thuban/UI/viewport.py (ViewPort.calc_min_max_scales): New.
18            Calculates the minimum and maximum scale values. Factored out
19            of set_view_transform so that it could be used to zoom all the
20            way into a single point.
21            (ViewPort.set_view_transform): Call calc_min_max_scales().
22            (ViewPort.FitSelectedToWindow): Zoom to the maximum scale
23            if only a single point is selected.
24    
25            * Doc/manual/images/1_2_legend_close.png,
26            Doc/manual/images/1_2_legend_dock.png,
27            Doc/manual/images/1_2_mainwindow.png,

43            Doc/manual/images/3_5_totop.png,
44            Doc/manual/images/3_5_visible.png: New. Images for the documentation.
45    
46    2003-07-18  Bernhard Herzog  <[email protected]>
47    
48            * Thuban/UI/messages.py (MAP_REPLACED): New message.
49    
50            * Thuban/UI/viewport.py (ViewPort.SetMap): Issue MAP_REPLACED
51            after the new map has been assigned
52    
53            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages):
54            Delegate MAP_REPLACED to the canvas too
55            (MainWindow.prepare_new_session): Removed. Thanks to the new
56            MAP_REPLACED message it's no longer needed
57            (MainWindow.OpenSession, MainWindow.NewSession):
58            prepare_new_session has been removed.
59    
60            * Thuban/UI/classifier.py (Classifier.__init__): Subscribe to
61            MAP_REPLACED so that we can close the dialog if a new map is set.
62            (Classifier.unsubscribe_messages): Unsubscribe from MAP_REPLACED
63            (Classifier.map_replaced): Handle MAP_REPLACED by closing the
64            dialog
65    
66            * test/test_viewport.py (SimpleViewPortTest)
67            (SimpleViewPortTest.test_default_size): Add doc-strings
68            (ViewPortTest.setUp): Bind map to self.map so we can use it in
69            tests. Subscribe to MAP_REPLACED messages too.
70            (ViewPortTest.tearDown): No need to explicitly unsubscribe
71            (ViewPortTest.test_set_map): New test for the SetMap method.
72    
73    2003-07-18  Bernhard Herzog  <[email protected]>
74    
75            * test/test_viewport.py (SimpleViewPortTest.test_default_size):
76            Move this test from ViewPortTest.setUp to this new separate test
77            case. setUp is not the place for the actual tests.
78            (ViewPortTest.test_inital_settings, ViewPortTest.setUp): Move some
79            more of the test from setUp to the new test test_inital_settings.
80            (ViewPortTest.test_win_to_proj, ViewPortTest.test_proj_to_win)
81            (ViewPortTest.test_proj_conv): Split test_proj_conv into
82            test_win_to_proj and test_proj_to_win and make the tests easier to
83            understand
84            (ViewPortTest.testFitRectToWindow, ViewPortTest.testZoomFactor)
85            (ViewPortTest.testZoomOutToRect, ViewPortTest.testTranslate)

93    
94    2003-07-18  Bernhard Herzog  <[email protected]>
95    
96            * test/runtests.py: The test suite can now be run without an X
97            connection. To make sure this remains true, remove the DISPLAY
98            environment variable so that an error occurs if the wxGTK is
99            imported accidentally
100    
101    2003-07-18  Bernhard Herzog  <[email protected]>
102    
103            * Thuban/UI/viewport.py: Remove unused imports

107    2003-07-18  Bernhard Herzog  <[email protected]>
108    
109            * test/test_export.py Remove unused imports. The OutputTransform
110            function is now in viewport.py and is called output_transform
111            (TestScalebar.test_output_transform)
112            (TestScalebar.test_OutputTransform): Renamed to
113            test_output_transform and updated to use output_transform instead
114            of OutputTransform
115    
116            * Thuban/UI/view.py (OutputTransform): Moved to viewport.py and
117            renamed.
118            (MapCanvas.Export, MapPrintout.draw_on_dc): OutputTransform was
119            renamed to output_transform
120    
121            * Thuban/UI/viewport.py (OutputTransform, output_transform):
122            Rename to output_transform
123    
124    2003-07-18  Bernhard Herzog  <[email protected]>
125    
126            * Thuban/Model/layer.py (Layer.__init__): Rename
127            classificationField to classificatin_column and init it here so
128            that it can be used in SetClassificationColumn
129            (Layer.GetClassificationColumn, Layer.GetClassificationField):
130            Rename to GetClassificationColumn.
131            (Layer.SetClassificationColumn, Layer.SetClassificationField):
132            Rename to SetClassificationColumn and issue a LAYER_CHANGED
133            message if the column changes.
134            (Layer._classification_changed, Layer.ClassChanged): Rename to
135            _classification_changed. Update the callers.
136            (Layer.SetShapeStore): Further field->column renames.
137    
138            * Thuban/Model/load.py (SessionLoader.start_classification)
139            (SessionLoader.start_clpoint): Updates because of
140            field->column method name changes in the Layer class
141    
142            * Thuban/Model/save.py (SessionSaver.write_classification): Updates
143            because of field->column method name changes in the Layer class
144    
145            * Thuban/UI/classifier.py (Classifier.__init__)
146            (Classifier._OnTry, Classifier._OnRevert): Updates because of
147            field->column method name changes in the Layer class
148    
149            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Updates
150            because of field->column method name changes in the Layer class
151    
152            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Updates because
153            of field->column method name changes in the Layer class
154    
155            * test/test_save.py (SaveSessionTest.testClassifiedLayer)
156            (SaveSessionTest.testClassifiedLayer): Update because of
157            field->column method name changes in the Layer class
158    
159            * test/test_layer.py (SetShapeStoreTests.setUp)
160            (SetShapeStoreTests.test_sanity): Update because of field->column
161            method name changes in the Layer class
162            (TestLayerModification.setUp): Subscribe to LAYER_CHANGED as well
163            (TestLayerModification.test_sanity)
164            (TestLayerModification.test_initial_settings): remove unsued code
165            and rename to test_sanity.
166            (TestLayerModification.test_set_classification): New test for
167            SetClassification and SetClassificationField.
168    
169    2003-07-18  Bernhard Herzog  <[email protected]>
170    
171            * test/test_classgen.py (TestFixedRamp.test): Extend test to check
172            the non-fixed values as well. The old test would have accepted a
173            fixed ramp that only returnes the fixed properties
174    
175    2003-07-17  Jonathan Coles   <[email protected]>
176    
177            * Doc/manual/mainwindow.png, Doc/manual/mainwindow.xcf: Screen
178            shots for the manual. The XCF file is the source image and
179            has additional layers to support changes.
180    
181            * Doc/manual/thuban-manual.xml: Wrote an initial Introduction.
182    
183            * Thuban/UI/classifier.py (Classifier.__BuildClassification):
184            Return both the new class and the field name.
185    
186            * Thuban/UI/mainwindow.py (MainWindow.ToggleLegend): Don't
187            fit the map to the window as this changes any zoom level that
188            the user may have set.
189    
190    2003-07-16  Jonathan Coles   <[email protected]>
191    
192            * Thuban/Model/classgen.py (generate_singletons,
193            generate_uniform_distribution, generate_quantiles): Remove
194            fixes parameter, but maintain the same functionality by having
195            the calling function pass a FixedRamp object for the ramp.
196            (FixedRamp): New. Adapts a ramp to have fixed property values.
197    
198            * Thuban/Model/classification.py: Use new CLASS_CHANGED message.
199            (Classification): Inherit from Publisher.
200            (Classification.__init__): Remove the layer parameter.
201            Classifications no longer need to have a parent layer.
202            (Classification.GetField, Classification.GetFieldType,
203            Classification.SetFieldInfo): Removed. The field name is stored
204            in the layer, and the type can be retreived by calling
205            Layer.GetFieldType().
206            (Classification._set_layer, Classification.GetLayer): Removed.
207            Classifications no longer have a parent layer.
208    
209            * Thuban/Model/layer.py (Layer.Destroy): Unsubscribe from the
210            classification.
211            (Layer.SetShapeStore): Reset the classification first while
212            we still have the old shape store to work with.
213            (Layer.GetClassificationField, Layer.SetClassificationField):
214            New. Method for getting/setting the field to classify on.
215            (Layer.SetClassification): Simplified now that the layer
216            simply has to hold a reference to the classification and not
217            tell the classification who owns it.
218            Fixes RTbug #2023.
219    
220            * Thuban/Model/load.py (SessionLoader.start_classification):
221            Set the field name on the layer, not the classification.
222    
223            * Thuban/Model/messages.py: Add CLASS_CHANGED for when a
224            classification is modified.
225    
226            * Thuban/Model/save.py (SessionSaver.write_classification):
227            Get the field name and type from the layer.
228    
229            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Renamed
230            parameter records to rows and add docstring. Fixes RTbug #1997.
231    
232            * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Use a fixed
233            ramp when we need to fix certain values of a ramp rather than
234            using the old fixes parameter. Fixes RTbug #2024.
235    
236            * Thuban/UI/classifier.py (ClassGrid.CreateTable): Add fieldType
237            parameter.
238            (ClassTable.Reset): Add fieldType parameter and use it, rather
239            than asking the classification.
240            (Classifier.__init__): Remember the original class's field
241            and ask the layer for the field type, rather than the classification.
242            (Classifier.__SetGridTable): Retrieve the field and field type
243            for the table because they are not in the classification.
244            (Classifier._OnTry, Classifier._OnRevert): Set the classification
245            field on the layer in addition to the classification itself.
246    
247            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Get the
248            classification field from layer.
249    
250            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Get the
251            classification field from layer. Split up tests and remove
252            *-imports. Fixes RTbug #1992.
253    
254            * test/test_classgen.py (TestFixedRamp): Test for the FixedRamp class.
255    
256            * test/test_classification.py
257            (TestClassification.test_classification): Remove tests for methods
258            that no longer exist.
259    
260            * test/test_layer.py (SetShapeStoreTests.setUp): Classification
261            __init__ no longer has a field parameter, use SetClassificationField.
262            (SetShapeStoreTests.test_sanity): Use layer object to get class
263            field info.
264    
265            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Use
266            SetClassificationField on layer to set class field info.
267    
268            * test/test_viewport.py: Renamed from test/test_view.py.
269    
270    2003-07-16  Jan-Oliver Wagner <[email protected]>
271    
272            * Doc/manual/thuban-manual.xml: Added authors and an initial
273            coarse structure.
274    
275    2003-07-15  Bernhard Herzog  <[email protected]>
276    
277            * test/support.py (FloatComparisonMixin): This is a mix-in class
278            and therefore should not be derived from any other class.
279    
280            * test/test_range.py (RangeTest): FloatComparisonMixin is a
281            mix-in, so derive from TestCase as well.
282    
283    2003-07-15  Bernhard Herzog  <[email protected]>
284    
285            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Rework the
286            draw_func handling a bit to remove one layer of indirection. This
287            makes the renderer about 10% faster in the non-classifying case
288            and the code a bit cleaner
289            (MapRenderer.draw_point_shape): Add the pen and brush parameters
290            and set them in the dc. Now the draw_point_shape method and
291            wxproj's draw_polygon_shape function have basically the same
292            signature so that both can be directly used as draw_func
293    
294    2003-07-15  Bernhard Herzog  <[email protected]>
295    
296            * Thuban/Model/save.py (SessionSaver.write_classification): Encode
297            string values (in addition to the labels) as UTF 8
298    
299            * Thuban/Model/load.py (SessionLoader.start_clpoint): Decode the
300            values if the field type is string
301    
302            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Test
303            saving a session with non-ascii string classification values.
304    
305            * test/test_load.py (TestClassification.file_contents)
306            (TestClassification.test): Check for non-ascii values in string
307            classifications
308    
309    2003-07-14  Jonathan Coles   <[email protected]>
310    
311            * test/test_view.py: New. Tests for ViewPort.
312    
313    2003-07-14  Frank Koormann   <[email protected]>
314    
315            * Thuban/Model/load.py (SessionLoader.start_map): Encode map
316            title to latin1.  Fixes https://intevation.de/rt/webrt?serial_num=2013
317    
318            * test/test_load_0_8.py (TestUnicodeStrings): New, test load of
319            unicode strings from session file: session title, map title and
320            projection name.
321            
322    2003-07-10  Jonathan Coles   <[email protected]>
323    
324            * Thuban/UI/viewport.py (Tool.MouseUp): Should have called
325            drag_stop, not drag_move when the mouse is released.
326    
327    2003-07-10  Jonathan Coles   <[email protected]>
328    
329            The most important part of this is the seperation of view.py into
330            two pieces. viewport.py now has a class called ViewPort which
331            contains all the non-wx parts of view.py and can therefore be
332            tested. view.py contains only the wx-specific parts and is fairly
333            simple.
334    
335            * Thuban/UI/view.py: Stripped out all non-wx functionality. Fixes
336            RTTbug #1992.
337            * Thuban/UI/viewport.py: New. Contains non-wx view functionality.
338            RTTbug #1992.
339    
340            * Thuban/Model/classgen.py (generate_singletons,
341            generate_uniform_distribution, generate_quantiles):
342            Added 'fixes' parameter so that property attributes can
343            be held constant over the generated classification groups.
344            (CustomRamp.GetProperties): Remove unused variables.
345    
346            * Thuban/Model/map.py (Map.SetProjection): Send the old
347            projection as an argument to listeners of the MAP_PROJECTION_CHANGED
348            event.
349    
350            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Added 'records'
351            parameter which is a list of records that restricts which
352            records are saved. Fixes RTbug #1997.
353    
354            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
355            Port exception dialog from GREAT-ER. Fixes RTbug #1993.
356    
357            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Add controls
358            to allow the user to fix line color/width on generated groups.
359            (ClassGenDialog.OnOK): Use new 'fixes' parameter of the generate_*
360            functions to optionally fix group properties.
361    
362            * Thuban/UI/main.py (main): Set exception hook to the
363            ShowExceptionDialog. Fixes RTbug #1993.
364    
365            * Thuban/UI/mainwindow.py (MainWindow.ShowTableView): Raise
366            the table window when it is selectd to be shown.
367    
368            * Thuban/UI/tableview.py (QueryTableFrame.__init__): Add an
369            Export Selection button and move the export buttons underneath
370            the table.
371            (QueryTableFrame.UpdateStatusText): Added event argument so
372            that it can respond to grid selection events. The status text
373            is now updated even when the table is not associated with a
374            layer as was previously assumed.
375            (QueryTableFrame.OnGridSelectRange, OnGridSelectCell): Removed.
376            UpdateStatusText responds to these events.
377            (QueryTableFrame.OnSaveAs): Renamed to doExport.

435    2003-07-08  Bernhard Herzog  <[email protected]>
436    
437            * Resources/XML/thuban-0.9.dtd: New. This will become the DTD for

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

513    
514    2003-07-02  Jonathan Coles   <[email protected]>
515    
516            * Thuban/Model/classgen.py (generate_singletons,
517            generate_uniform_distribution, generate_quantiles,
518            GenQuantiles0): Make sure maxValue isn't less than
519            one, otherwise we could divide by zero.
520    
521            * test/test_classgen.py (ClassGenTest.doClassRangeTest,
522            ClassGenTest.doClassSingleTest): Call doBoundsTest to
523            check the end classification groups against the
524            proper property values.
525            (ClassGenTest.doBoundsTest): New. Checks the first and
526            last classification groups to make sure their properties
527            are the correct upper and lower bounds for a color ramp.
528    
529    2003-07-02  Jonathan Coles   <[email protected]>
530    
531            * Thuban/Model/classgen.py (generate_singletons,
532            generate_uniform_distribution, generate_quantiles,
533            GenQuantiles0): The denominator was one to high when
534            calculating the index for the ramp causing the index
535            to never to reach one.
536    
537    2003-07-02  Jonathan Coles   <[email protected]>
538    
539            Changed the singature of ClassGroupRange.__init__ and
540            ClassGroupRange.SetRange() so that the min/max values are
541            passed as a tuple. This makes a better calling scheme for
542            when a Range object is passed instead.
543    
544            * Thuban/Model/classgen.py: Fixed parameters to
545            ClassGroupRange constructor.
546    
547            * Thuban/Model/classification.py (ClassGroupRange.__init__):
548            Consolidate the min/max parameters into a single _range which
549            can either be a tuple or a Range object.
550            (ClassGroupRange.SetRange): Consolidate the min/max parameters
551            into a single _range which can either be a tuple or a Range object.
552    
553            * Thuban/Model/load.py (SessionLoader.start_clrange): Fix
554            call to ClassGroupRange constructor to use a tuple.
555    
556            * Thuban/Model/layer.py (Layer.SetClassification): Switch
557            the classification instance variable to the new class
558            before calling _set_layer otherwise subscribers to a
559            LAYER_CHANGED event will not see any difference.
560    
561            * test/test_classification.py: Fix tests of ClassGroupRange
562            so that they use the new signature.
563    
564            * test/test_load.py: Fix use of ClassGroupRange so that it
565            uses the new signature.
566    
567            * test/test_load_0_2.py: Fix use of ClassGroupRange so that it
568            uses the new signature.
569    
570            * test/test_save.py: Fix use of ClassGroupRange so that it
571            uses the new signature.
572    
573    
574    2003-07-01  Jonathan Coles   <[email protected]>
575    
576            * Thuban/Model/classgen.py: Fixes RTbug #1972, 1971.
577            Import used objects/class from color.
578            (generate_singletons): We don't
579            need the numGroups parameter anymore because we are using
580            the new ramps with GetProperties().
581            (generate_uniform_distribution): Use new ramp method
582            GetProperties().
583            (generate_quantiles, GenQuantiles0): Use new ramp method
584            GetProperties().
585            (CustomRamp.SetNumGroups): Removed. The ramps now map
586            a value from 0 to 1 to class properties so the number
587            of groups is not needed ahead of time.
588            (CustomRamp.next): Removed. CustomRamp does not support
589            interation anymore.
590            (CustomRamp.GetProperties): Returns a ClassGroupProperties
591            object based on the index value from 0 to 1 that is
592            passed to it.
593            (GreyRamp, RedRamp, GreenRamp, BlueRamp, GreenToRedRamp):
594            Made into instances of Monochromatic class instread of
595            deriving from it.
596            (HotToCold.SetNumGroups): Removed. See CustomRamp.
597            (HotToCold.next): Removed. See CustomRamp.
598    
599            * Thuban/Model/classification.py: Fixes RTbug #1973, 1971.
600            (Classification.SetField, Classification.SetFieldType):
601            Replaced with SetFieldInfo.
602            (Classification.SetFieldInfo): New. Does a better job of
603            what SetField and SetFieldType used to do by combining
604            their function since they should really always be done
605            at the same time.
606            (Classification.SetLayer): Renamed to _set_layer.
607            (Classification._set_layer): Should only be called from
608            Layer's SetClassification. This does not cause a recursive
609            call as SetLayer did because we know that Layer knows about
610            the classification.
611    
612            * Thuban/Model/color.py: Fixes RTbug #1971.
613            (_Transparent): Renamed from Transparent so it doesn't
614            conflict with the module variable.
615            (Transparent, Black): Renamed from Color.Transparent,
616            Color.Black so they are not class variables.
617    
618            * Thuban/Model/layer.py: Fixes RTbug #1971, 1973.
619            (Layer.Destroy): We don't need to call SetClassification
620            anymore to clear out the back reference in the classifcation
621            to the layer. It's better to set it to None using _set_layer,
622            and we won't be creating another clas object too.
623            (Layer.SetClassification): Classification._set_layer is not
624            recursive so remove all the locking variables. Also clean
625            up the code so that it remains unchanged if something fails.
626    
627            * Thuban/Model/load.py: Fixes RTbug #1971.
628            (SessionLoader.start_classification): Call
629            Classification.SetFieldInfo().
630    
631            * Thuban/Model/save.py: Removed import of Color which wasn't
632            being used.
633    
634            * Thuban/UI/classgen.py: Fixes RTbug #1972.
635            (ClassGenDialog.__init__): Color ramps are now instances
636            already so we don't need to create any new objects.
637            (ClassGenDialog.OnOK): Check for numGroups is no longer
638            necessary because we never use it.
639    
640            * Thuban/UI/classifier.py: Fixes RTbug #1971.
641            (Classifier.__BuildClassification, Classifier.__SetGridTable):
642            Call Classification.SetFieldInfo() instead of SetFieldType.
643    
644            * Thuban/UI/renderer.py: Fixes RTbug #1971.
645    
646            * Thuban/UI/view.py: Fixes RTbug #1974, 1971.
647            (MapCanvas.__init__): Subscribe to the idle time event. Set
648            background color to white.
649            (MapCanvas.OnPaint): Set a flag indicating that we should
650            render the map during idle time. If we already have a bitmap
651            just draw it now.
652            (MapCanvas.OnIdle): New. Render the map only during idle time.
653            This also fixes a problem with the busy cursor under gtk.
654    
655            * test/test_classgen.py (ClassGenTest.test_generate_singletons):
656            Fix calls to generate_singletons because the signature changed.
657    
658            * test/test_classification.py: Fix color references and
659            change calls to Classification.[SetField|SetFieldType] to
660            SetFieldInfo.
661    
662            * test/test_load.py: Fix color references.
663    
664            * test/test_load_0_2.py: Fix color references.
665    
666            * test/test_save.py (SaveSessionTest.testClassifiedLayer):
667            Change calls to Classification.[SetField|SetFieldType] to
668            SetFieldInfo.
669

677    
678            * Thuban/Model/transientdb.py (TransientJoinedTable.create):
679            If duplicates in left and right tables column names are found,
680            append '_' (underscores) to the name until it is unique.
681            Create always new internal names for the resulting table and reference
682            columns in the join statement with <table>.<column>

703            * Thuban/version.py (make_tuple): Takes a version string
704            and splits it into a tuple of at most three integers.

778    2003-06-23  Jonathan Coles   <[email protected]>
779            
780            * setup.py: Add Resources/XML to resource list.
781        
782    2003-06-23  Jonathan Coles   <[email protected]>
783    
784            * setup.cfg: Fix copyright dates
785        
786    2003-06-23  Jonathan Coles   <[email protected]>
787    
788            * MANIFEST.in: Update with Resources/XML
789    
790            * setup.py: Don't include Locale resources yet as we don't
791            have any and it causes problems building the distribution
792            for Windows. Update version to 0.8.0.
793    
794            * Doc/thuban.dtd: Removed since it is now in Resources/XML.
795    
796            * Thuban/UI/mainwindow.py: Add blank line at the end because
797            file was not being read correctly building the Windows
798            distribution.
799    
800    2003-06-23  Jonathan Coles   <[email protected]>
801    
802            * Thuban/UI/mainwindow.py (MainWindow.About): Fix text.
803    
804            * Thuban/version.py: Temporarily update longversion for
805            the 0.8 release so that it doesn't have the cvs revision.
806    
807    2003-06-23  Jonathan Coles   <[email protected]>
808    
809            * Thuban/UI/common.py (ThubanBeginBusyCursor): Call wxSafeYield
810            to make sure that we don't create reentrant possibilities with
811            wxYield.
812    
813            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxBeginBusyCursor()
814            directly to avoid the wxSafeYield() call which generates an
815            OnPaint event causing infinite recursion. Don't try to catch
816            exception anymore. This was for before there were limits on map
817            scaling.
818    
819    2003-06-23  Bernhard Herzog  <[email protected]>
820    
821            Bug fix for RT #1961:
822    
823            * Thuban/Model/load.py (SessionLoader.start_derivedshapesource):
824            Register DerivedShapestores with the session
825    
826            * Thuban/Model/session.py (Session.Tables): Make sure each table
827            is only listed once.
828    
829            * test/test_load.py (TestJoinedTable.test): Add check_format call.
830            Update file contents to match the one written out.
831    
832    2003-06-20  Bernhard Herzog  <[email protected]>
833    
834            * test/xmlsupport.py (SaxEventLister.startElementNS)
835            (SaxEventLister.endElementNS): Do not include the qname. Python
836            2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
837            is (presumably incorrectly) None, whereas it's a string with the
838            element name in the later versions.
839    
840            * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
841            (TestEventList.test_even_list_namespace): Update tests to reflect
842            the new behaviour
843            (TestEventList.test_even_list_id_normalization): Fix doc-string
844    
845    2003-06-20  Jonathan Coles   <[email protected]>
846    
847            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
848            by deriving classes to determine if that layer supports shapes.
849            (Layer): Override HasShapes and return true.
850    
851            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
852            instead of a direct call to wx[Begin|End]CusyCursor().
853            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
854            table data.
855    
856            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
857            New. Wrappers around the wxWindows functions that allow us to
858            make additional calls such as wxYield which gives the native
859            system a chance to update the cursor correctly.
860    
861            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
862            instead of a direct call to wx[Begin|End]CusyCursor().
863    
864            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
865            instead of a direct call to wx[Begin|End]CusyCursor().
866            (MapCanvas.find_shape_at): Check if the current search layer
867            support shapes, otherwise go on to the next layer.
868    
869            * test/test_layer.py: Add tests in each type of layer for
870            HasClassification() and HasShapes()
871    
872    2003-06-20  Jonathan Coles   <[email protected]>
873    
874            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
875            turning on the busy cursor to allow the system to change the
876            cursor before we begin painting. This fixes a problem that
877            was occuring only under GTK. Fixes RTbug #1840.
878    
879    2003-06-20  Bernhard Herzog  <[email protected]>

901            errors in the files are discovered
902            (SessionLoader.__init__): Define dispatchers for elements with a
903            thuban-0.8 namespace too.

912            addition to filename.
913            (SessionLoader.start_table, SessionLoader.end_table): Removed.
914            They were never used in the old formats and aren't needed for the
915            new.
916    
917            * Thuban/Model/session.py (Session.DataContainers): New method to
918            return all "data containers", i.e. shapestores and tables
919    
920            * test/xmlsupport.py (SaxEventLister.__init__)
921            (SaxEventLister.startElementNS, sax_eventlist): Add support to
922            normalize IDs.
923    
924            * test/test_xmlsupport.py
925            (TestEventList.test_even_list_id_normalization): New test case for
926            id normalization
927    
928            * test/test_load.py (LoadSessionTest.check_format): Use ID
929            normalization
930            (LoadSessionTest.thubanids, LoadSessionTest.thubanidrefs): New
931            class atrributes used for ID normalization

951            (SaveSessionTest.test_joined_table): New test cases for saving the
952            new data sources structures.
953            (TestStoreSort, MockDataStore): Classes to test the sorting of the
954            data stores for writing.
955    
956            * test/runtests.py: Add CVS keywords
957    
958    2003-06-20  Jonathan Coles   <[email protected]>
959    
960            * test/test_session.py
961            (UnreferencedTablesTests.test_unreferenced_tables_with_joins):
962            Use the cultural_landmark-point.dbf file for the store so that
963            the table rows and shape count match.
964    
965    2003-06-20  Jonathan Coles   <[email protected]>
966    
967            * Thuban/Model/data.py (DerivedShapeStore.__init__): Raise
968            an exception if the number of shapes is different from the
969            number of rows in the table. Address RTbug #1933.
970    
971            * test/test_layer.py (TestLayer.test_derived_store): Add
972            a test for the new exception in DerivedShapeStore.__init__.
973    
974            * test/support.py (FloatTestCase): Removed since there is
975            already FloatComparisonMixin. Fixes RTbug #1954.
976            (FloatComparisonMixin.assertFloatEqual): Include test for
977            infinity that was part of FloatTestCase.
978    
979            * test/test_range.py (RangeTest): Inherit from
980            support.FloatComparisonMixin now that we don't have
981            support.FloatTestCase.
982    
983    2003-06-20  Bernhard Herzog  <[email protected]>
984    
985            * test/test_save.py (SaxEventLister, sax_eventlist): Removed. Use
986            the implementation in xmlsupport instead.
987            (SaveSessionTest.compare_xml): sax_eventlist is now in xmlsupport
988    
989            * test/test_proj.py: Import sax_eventlist from xmlsupport instead
990            of test_save
991    
992    2003-06-20  Bernhard Herzog  <[email protected]>
993    
994            * test/test_load.py (LoadSessionTest.check_format): New helper
995            method to make sure the test files we load might have been written
996            by the current thuban version.
997            (ClassificationTest.TestLayers, TestSingleLayer.test)
998            (TestLayerVisibility.test, TestClassification.test)
999            (TestLabels.test, TestLayerProjection.test, TestRasterLayer.test):
1000            Add check_format() calls and fix the thuban data to match the data
1001            that would be written by saving the session loaded from it.
1002    
1003            * test/xmlsupport.py (SaxEventLister, sax_eventlist): Copies of
1004            the same class and function in test_save.
1005    
1006            * test/test_xmlsupport.py (TestEventList): New. test cases for
1007            sax_eventlist
1008    
1009    2003-06-20  Bernhard Herzog  <[email protected]>
1010    
1011            * Resources/XML/thuban.dtd: Add comment about which versions of
1012            Thuban are covered by this DTD
1013            (map): Fix content model for layers and raster layers. There can
1014            be any number or layers and raster layers in any order.
1015    
1016    2003-06-20  Jonathan Coles   <[email protected]>
1017    
1018            This is mainly about fixing RTbug #1949.
1019    
1020            * Thuban/Model/classification.py: Remove "from __future__"
1021            import statement since python 2.2 is the earliest supported
1022            version.
1023    
1024            * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
1025            Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES
1026            depending on the units this projection *forwards* into.
1027    
1028            * Thuban/Model/save.py (SessionSaver.write_classification):
1029            Remove unnecessary use of lambdas and nested functions.
1030    
1031            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Do scale
1032            adjustment here if the map projection uses degrees.
1033    
1034            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
1035            scale adjust code since it is now done before calling
1036            this method. Don't do anything if the map projection
1037            is None.
1038    
1039    2003-06-19  Bernhard Herzog  <[email protected]>
1040    
1041            Move version specific load tests to their own file.
1042    
1043            * test/test_load.py: Expand the doc-string to explain a bit how to
1044            handle file format changes.
1045            (TestClassification.test): Update the docstring as this test is
1046            not about Thuban 0.2 anymore.
1047    
1048            * test/test_load_0_2.py: New file with the load tests for thuban
1049            files created with Thuban 0.2 and earlier.
1050    
1051    2003-06-19  Bernhard Herzog  <[email protected]>
1052    
1053            Add XML validation to some of the tests. Validation will only be
1054            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
1055            To make the DTD available to the test cases it's moved into
1056            Resources/XML
1057    
1058            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
1059            for versions up to and including 0.2. Two slight changes: added an
1060            encoding specification and fixed the comment which refered to
1061            GRASS, not Thuban
1062    
1063            * test/xmlsupport.py: New support module for tests involving XML.
1064            Currently there's a mix-in class for XML validation.
1065    
1066            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
1067    
1068            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
1069            so that we can validate the
1070            (SaveSessionTest.testEmptySession)
1071            (SaveSessionTest.testSingleLayer)
1072            (SaveSessionTest.testSingleLayer)
1073            (SaveSessionTest.testLayerProjection)
1074            (SaveSessionTest.testRasterLayer)
1075            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
1076    
1077            * test/runtests.py (main): Call print_additional_summary instead
1078            of print_garbage_information
1079    
1080            * test/support.py (resource_dir): New function to return the
1081            "Resource" subdirectory
1082            (print_additional_summary): New function to combine several
1083            summary functions
1084            (run_tests): Use print_additional_summary instead of calling
1085            print_garbage_information directly
1086    
1087    2003-06-19  Bernhard Herzog  <[email protected]>
1088    
1089            * Doc/thuban.dtd (classification): Correct the content model of
1090            the classification element.
1091            (projection): Add the "name" attribute
1092    
1093    2003-06-19  Frank Koormann   <[email protected]>
1094    
1095            MERGE from the greater-ms3 branch.
1096    
1097            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
1098            scale if projection is latlong to get better estimate.
1099    
1100            Fix problem of hidden properties dialog under windows after double
1101            click on layer tree:
1102            The tree control always gets an Expanded / Collapsed event after
1103            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
1104            raises the already displayed window.
1105    
1106            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
1107            raiseProperties initialized to prevent endless loops
1108            (LegendTree._OnItemActivated): Depending on self.raiseProperties
1109            simply raise the properties or open the dialog and issue a second
1110            event.
1111    
1112    2003-06-18  Jonathan Coles   <[email protected]>
1113    
1114            * setup.py: Fix a few problems that occured under Windows.
1115    
1116    2003-06-18  Jonathan Coles   <[email protected]>
1117    
1118            When Thuban loaded the map was redrawn twice because the
1119            legend was being opened after the mainwindow was created
1120            and not during its creation. This meant the map was drawn
1121            initially and then had to be redrawn when the legend
1122            caused the display to change. Now the legend is opened
1123            in the mainwindow constructor which resolves this issue.
1124    
1125            Also, although we were checking for the existence of
1126            gdal and gdalwarp modules, the gdalwarp extension was
1127            still being compiled (which may fail if the system doesn't
1128            have gdal installed). the build_ext command to setup.py
1129            now accepts the flags --with-gdal and --without-gdal.
1130            If --without-gdal is specified setup.py will try to
1131            use the gdal parameters specified by gdal-config. Under
1132            windows, those parameters have to be set in setup.py
1133            as with proj4 an wxWindows.
1134    
1135            * setup.py: Use a list instead of seperate variables for
1136            extension parameters so we can create a generic function
1137            that runs an appropriate *-config script.
1138            (run_cs_script): Renamed from run_wx_script and modified
1139            to accept a second argument which is a list of lists to
1140            be filled in by the values returned from running the command.
1141            (thuban_build_ext): New. Extends the build_ext command and
1142            provides the options --with-gdal/--without-gdal which then
1143            optionally includes the gdalwarp extension.
1144    
1145            * Thuban/Model/resource.py: First check if we can import
1146            the gdalwarp Thuban extension before checking for gdal.
1147            Also added some comments.
1148            
1149            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
1150            the map is None which may be the case if none has been loaded
1151            yet.
1152    
1153            * Thuban/UI/main.py (main): Remove call to ShowLegend.
1154    
1155            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
1156    
1157            * Thuban/UI/renderer.py: Check for gdal support before importing
1158            gdalwarp.
1159            (MapRenderer.render_map): Only try to optimize if we have gdal
1160            support otherwise nothing will get drawn.
1161    
1162            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
1163            during startup before a map has been created. Check if map is None
1164            before using it and do nothing if it is.
1165

1167    
1168            Fix the problem with raster layers under Windows that caused
1169            Thuban to crash. The view should respond to layer projection
1170            changed events to update the display. Changes to a projection
1171            should not cause the map to be set to full extent.
1172            
1173            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
1174            current_map_proj to remember the current map projection so that
1175            when the projection changes we know what the previous projection
1176            was.
1177            (MapCanvas.SetMap): Unsubscribe and subscribe to
1178            LAYER_PROJECTION_CHANGED events.
1179            (MapCanvas.projection_changed): Split into two methods that respond
1180            to map and layer projection changes.
1181            (MapCanvas.map_projection_changed): New. Takes the current view and
1182            projects it using the new projection. This does not cause the
1183            map to be redrawn at full extent.
1184            (MapCanvas.layer_projection_changed): New. Cause a redraw which
1185            will draw each layer in its new projection.
1186            
1187            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
1188            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
1189            under Windows.
1190            
1191            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
1192            to twice sizeof(void*) because there are two digits for each
1193            hex byte.
1194    
1195    2003-06-16  Bernhard Herzog  <[email protected]>
1196    
1197            Update to the layer interface: Direct access to the table,
1198            shapetable, shapefile and filename attributes is now actively
1199            deprecated by issuing deprecation warnings for all places where
1200            this happens.
1201    
1202            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
1203            to the instance variables table, shapetable, shapefile and
1204            filename via __getattr__ so that we can issue a deprecation
1205            warning.
1206            (Layer.SetShapeStore): Don't set the deprecated instance variables
1207            any more
1208            (Layer.SetShapeStore): Don't use deprecated layer instance
1209            variables
1210            (Layer.Destroy): No need to explicitly remove the instance
1211            variables any more
1212            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
1213            instance variables
1214    
1215            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
1216            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
1217            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
1218            use deprecated layer instance variables
1219    
1220            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
1221            deprecated layer instance variables
1222    
1223            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
1224            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
1225            instance variables
1226    
1227            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
1228            deprecated layer instance variables
1229    
1230            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
1231            deprecated layer instance variables
1232    
1233            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
1234            deprecated layer instance variables
1235    
1236            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
1237            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
1238            variables
1239    
1240            * test/runtests.py (main): Turn Thuban's deprecation warnings into
1241            errors so that they're cought by the tests
1242    
1243            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
1244            layer instance variables
1245    
1246    2003-06-16  Jonathan Coles   <[email protected]>
1247    
1248            Fix a problem under Windows whereby if the user double-clicks on a
1249            layer in the legend that tree item will expand or collapse as well
1250            as open the layer properties dialog. The state of the tree item
1251            should not be affected.
1252    
1253            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
1254            preventExpandCollapse and subscribe to expanding and collapsing
1255            events.
1256            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
1257            collapsing events and will veto the event if it has been triggered
1258            by the user double clicking on a layer.
1259            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
1260            that an expanding/collapsing event should be vetoed.
