3            Make the renderers deal correctly with raw vs. python level
4            representation of shape geometries
5    
6            * Thuban/UI/baserenderer.py (BaseRenderer.low_level_renderer):
7            Return a flag useraw in addition to the callable and the parameter
8            to indicate whether the callable can deal with the raw shape data
9            or uses the higher level python lists of coordinates. The callable
10            now should accept either the raw data or the return value of the
11            shape's Points() method.
12            (BaseRenderer.draw_shape_layer): Adapt to the low_level_renderer
13            change
14            (BaseRenderer.projected_points): Instead of the shape id use the
15            points list as parameter.
16            (BaseRenderer.draw_polygon_shape, BaseRenderer.draw_arc_shape)
17            (BaseRenderer.draw_point_shape): Adapt to projected_points()
18            change and accept the points list as parameter instead of the
19            shape id.
20    
21            * Thuban/UI/renderer.py (MapRenderer.low_level_renderer): Return
22            the useraw flag as required by the BaseRenderer
23            (ScreenRenderer.draw_shape_layer): Adapt to low-level renderer
24            changes.
25    
26            * test/test_baserenderer.py
27            (TestBaseRenderer.test_point_with_classification): New test for
28            rendering a map with classifications.
29    
30    2003-08-15  Bernhard Herzog  <[email protected]>
31    
32            * Thuban/UI/viewport.py (ViewPort.find_shape_at)
33            (ViewPort._find_shape_in_layer, ViewPort._find_shape_in_layer)
34            (ViewPort._get_hit_tester, ViewPort.projected_points)
35            (ViewPort._hit_point, ViewPort._hit_arc, ViewPort._hit_polygon)
36            (ViewPort._find_label_at): Split the find_shape_at method into
37            several new methods and use the functions in the hit-test module.
38    
39            * Thuban/UI/hittest.py: New module with Python-level hit-testing
40            functions
41    
42            * test/test_hittest.py: New. Test for the new hittest module
43    
44    2003-08-15  Bernhard Herzog  <[email protected]>
45    
46            * Thuban/Model/layer.py (Layer.ShapesInRegion): Apply the layer
47            projection to all corners of the bounding box to get a better
48            approximation of the projected bounding box
49    
50            * test/test_layer.py (TestLayer.test_point_layer_with_projection):
51            New. Test coordinate handling of a layer with a projection.
52            Catches the bug fixed in Layer.ShapesInRegion
53    
54    2003-08-15  Bernhard Herzog  <[email protected]>
55    
56            Move some of the mock objects in test_baserenderer into their own
57            module so they can easily be used from other tests
58    
59            * test/mockgeo.py: New test helper module with some mock objects
60            for geometry related things like shapes, shapestores and
61            projections.

82    
83            * test/support.py (FloatComparisonMixin.assertPointListEquals):
84            New. This method was used in various derived classes, but it's
85            better to have it here.
86    
87            * test/test_shapefilestore.py
88            (ShapefileStoreTests.assertPointListEquals): Removed. It's now in

112            the list corresponds to the "About" web page.
113    
114    2003-08-08  Bernhard Herzog  <[email protected]>
115    
116            * Thuban/UI/projdialog.py (UTMProposeZoneDialog.dialogLayout):
117            Make sure translated strings are recognized as one string literal.

127    
128    2003-08-07  Bernhard Herzog  <[email protected]>
129    
130            * Thuban/Model/data.py (DerivedShapeStore.RawShapeFormat): New.
131            Simply delegates to the original shapestore.
132    
133            * test/test_derivedshapestore.py
134            (TestDerivedShapeStore.test_raw_format): New. Test case for
135            DerivedShapeStore.RawShapeFormat
136    
137    2003-08-07  Bernhard Herzog  <[email protected]>
138    
139            Add raw data interface to shape objects.
140    
141            * Thuban/Model/data.py (ShapefileShape, Shape): Rname the shape
142            class to ShapefileShape which now holds shapefile specific
143            information.
144            (ShapefileShape.compute_bbox): Simplified to not cache any
145            information. The way this method is used that shouldn't matter
146            performance wise.
147            (ShapefileShape.RawData): New. Return the shapeid which is the raw
148            data format for shapes from shapefiles.
149            (ShapefileStore.RawShapeFormat): New. Return the raw datatype used
150            in the shape objects returned by a shapestore. For a
151            ShapefileStore this is always RAW_SHAPEFILE.
152            (RAW_PYTHON, RAW_SHAPEFILE): Constants for the RawShapeFormat
153            method.
154    
155            * test/test_shapefilestore.py
156            (TestShapefileStore.test_raw_format): New test to test the raw
157            format feature of shapes.
158    
159            * Thuban/Model/layer.py: Remove the unused import of Shape from
160            data. It was only there for interface compatibility but it's not
161            used inside of Thuban and the generic Shape class has gone away.
162    
163            * Thuban/UI/renderer.py (MapRenderer.low_level_renderer): Check
164            the raw data format and only use an optimized version of its a
165            shapefile.
166    
167    2003-08-07  Bernhard Herzog  <[email protected]>
168    
169            * test/test_baserenderer.py (SimpleShape): Shape class for the
170            tests.
171            (SimpleShapeStore.Shape): Use SimpleShape instead of
172            Thuban.Model.data.Shape to make the tests independed of the coming
173            changes.
174    
175    2003-08-07  Bernhard Herzog  <[email protected]>
176    
177            * test/support.py (SkipTest, ThubanTestResult, ThubanTestRunner)
178            (ThubanTestProgram): New classes that extend the respective
179            classes from unittest. These new version support skipping tests
180            under certain expected conditions. In the Thuban test suite we
181            uses this for tests that require the optional gdal support.
182            (run_tests): Use ThubanTestProgram instead of the unittest.main()
183    
184            * test/runtests.py (main): Use the new ThubanTestRunner instead of
185            the normal one from unittest
186    
187            * test/test_layer.py (TestLayer.test_raster_layer): If this test
188            is not run because gdal support isn't available report this to the
189            runner.
190    
191            * test/test_baserenderer.py
192            (TestBaseRenderer.test_raster_no_projection): Do not run this test
193            if gdal support isn't available and report this to the runner.
194    
195    2003-08-06  Bernhard Herzog  <[email protected]>
196    
197            Rearrange the renderers a bit, partly in preparation for changes
198            required for the postgis merge, partly to make it more testable.
199            Also make the representation of coordinates in Shapes more
200            consistent.
201    
202            * Thuban/UI/renderer.py (MapRenderer): Most of the code/methods in
203            this class is now in BaseRenderer. This class is now practically
204            only a specialization of BaseRenderer for rendering to an actual
205            wx DC.
206            (ScreenRenderer.draw_shape_layer): Use self.low_level_renderer()
207            to get the shapetype specific rendering functions.
208    
209            * Thuban/UI/baserenderer.py: New file with the basic rendering
210            logic. The code in this file is completely independend of wx.

212    
213            * test/test_baserenderer.py: New. Test cases for BaseRenderer
214    
215            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
216            error_on_redraw to guard agains endless loops and stack overflows
217            when there's a bug in the rendering code that raises exceptions.
218            (MapCanvas.OnIdle, MapCanvas._do_redraw): Split the actual
219            rendering into a separate method _do_redraw so that error handling
220            is a bit easier. When an exception occurs, set error_on_redraw to
221            true. When it's true on entry to OnIdle do nothing and return
222            immediately.
223    
224            * Thuban/Model/data.py (ShapefileStore.Shape): For consistency, a
225            Shape object will always have the coordinates as a list of list of
226            coordinate pairs (tuples).
227            (Shape.compute_bbox): Adapt to new representation.
228    
229            * Thuban/UI/viewport.py (ViewPort.find_shape_at)

233            * test/test_shapefilestore.py
234            (ShapefileStoreTests.assertFloatTuplesEqual)
235            (ShapefileStoreTests.assertPointListEquals): Rename to
236            assertPointListEquals and change purpose to checking equality of
237            the lists returned by Shape.Points().
238            (TestShapefileStoreArc.test_shape)
239            (TestShapefileStorePolygon.test_shape)
240            (TestShapefileStorePoint.test_shape): Use the new
241            assertPointListEquals instead of assertFloatTuplesEqual
242    
243            * test/test_layer.py (TestLayer.assertFloatTuplesEqual)
244            (TestLayer.assertPointListEquals): Rename to assertPointListEquals
245            and change purpose to checking equality of the lists returned by
246            Shape.Points().
247            (TestLayer.test_arc_layer, TestLayer.test_arc_layer)
248            (TestLayer.test_polygon_layer, TestLayer.test_point_layer)
249            (TestLayer.test_derived_store): Use the new assertPointListEquals
250            instead of assertFloatTuplesEqual
251    
252            * test/test_derivedshapestore.py
253            (TestDerivedShapeStore.assertFloatTuplesEqual)
254            (TestDerivedShapeStore.assertPointListEquals): Rename to
255            assertPointListEquals and change purpose to checking equality of
256            the lists returned by Shape.Points().
257            (TestDerivedShapeStore.test_shape): Use the new
258            assertPointListEquals instead of assertFloatTuplesEqual
259    
260    2003-08-06  Jan-Oliver Wagner <[email protected]>
261    
262            * Thuban/UI/projdialog.py (UTMPanel._OnPropose): Added test for
263            a bounding box. A dialog is raised in case, no bounding box
264            is found. This fixes bug #2043:
265            https://intevation.de/rt/webrt?serial_num=2043
266    
267    2003-08-05  Bernhard Herzog  <[email protected]>
268    
269            * Thuban/Model/color.py (Color.__repr__): Make the repr of a color
270            object look like a Color instantiation. Formerly it looked like a
271            tuple.
272    
273            * test/test_color.py (TestColor.test_repr)
274            (TestColor.test_equality, TestColor.test_inequality): New. test
275            some more apects of the Color class
276            (TestTransparent.test_repr, TestTransparent.test_hex)
277            (TestTransparent.test_equality): New. Test cases for the
278            Transparent object.
279    
280    2003-08-04  Jan-Oliver Wagner <[email protected]>
281    
282            * Doc/manual/thuban-manual.xml: a number of small improvements.
283            The resulting file is the version submitted for GREAT-ER II.
284    
285    2003-08-01  Bernhard Herzog  <[email protected]>
286    
287            * Thuban/UI/resource.py, Thuban/UI/projdialog.py,
288            Thuban/UI/join.py, Thuban/UI/classgen.py, Thuban/UI/about.py,
289            Thuban/Model/resource.py: Insert cvs keywords and doc-strings.
290    
291            * Thuban/UI/common.py: Insert cvs keywords and doc-strings.
292            (Color2wxColour, wxColour2Color, ThubanBeginBusyCursor)
293            (ThubanEndBusyCursor): Add doc-strings
294    
295    2003-08-01  Bernhard Herzog  <[email protected]>
296    
297            First step towards PostGIS integration. More abstraction by movin
298            more code from the layer to the shapestore. More methods of the
299            layer are now simply delegated to the equivalent method of the
300            shapestore. The SHAPETYPE_* constants are now in data not in
301            layer.
302    
303            * Thuban/Model/data.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
304            (SHAPETYPE_POINT, Shape): Move these constants and classes from
305            layer.py to data.py
306            (ShapefileStore.__init__): More Initialization for the new methods
307            and functionality.

310            (ShapefileStore.Shape): New methods that were formerly implemented
311            in the layer.
312            (DerivedShapeStore.Shape, DerivedShapeStore.ShapesInRegion)
313            (DerivedShapeStore.ShapeType, DerivedShapeStore.NumShapes)
314            (DerivedShapeStore.BoundingBox): New. DerivedShapeStore
315            equivalents of the new shape methods. These versions are simply
316            delegated to the original shapstore.
317    
318            * Thuban/Model/layer.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
319            (SHAPETYPE_POINT, Shape): Removed. They're now in data.py
320            (Layer.SetShapeStore): Removed the initializatin of instance
321            variables that were needed for the stuff that's now in
322            ShapefileStore
323            (Layer.BoundingBox, Layer.NumShapes, Layer.ShapeType)
324            (Layer.Shape, Layer.ShapesInRegion): Simply delegate to the
325            shapestore.
326    
327            * Thuban/UI/classifier.py, Thuban/UI/renderer.py,
328            Thuban/UI/viewport.py: Import the SHAPETYPE_* constants from data
329            instead of layer.
330    
331            * test/test_shapefilestore.py: New. Tests for ShapefileStore.
332    
333            * test/test_derivedshapestore.py: New. Tests for DerivedShapeStore.
334    
335            * test/test_layer.py: Import the SHAPETYPE_* constants from data
336            instead of layer.
337            (TestLayer.test_derived_store): Remove the test for the exception
338            when instantiating the DerivedShapeStore with an incompatible
339            table which is now in test_derivedshapestore.py. Add some more
340            tests of the layer methods to determine whether they work for a
341            DerivedShapeStore as well.
342    
343    2003-07-31  Jonathan Coles   <[email protected]>
344    
345            * Doc/manual/thuban-manual.xml: Fix the list of required packages
346            by just listing the name and where they can be found.
347    
348    2003-07-31  Frank Koormann   <[email protected]>
349    
350            * Doc/manual/thuban-manual.xml:
351            Changed the screenshot elements to figure.
352            Changed some variablelist elements to itemizedlist.
353            Added section on GDAL formats.
354    
355    2003-07-31  Jonathan Coles   <[email protected]>
356    
357            * Doc/manual/thuban-manual.xml: Added a few sentences about
358            the Fix Border Color option when generating classes.
359    
360    2003-07-30  Jonathan Coles   <[email protected]>
361    
362            * Thuban/Model/classgen.py: Add docstrings. Rename specific
363            Ramp instances to use lower_case_style.
364    
365            * Thuban/UI/classgen.py: Use renamed Ramp instances.
366            
367            * Thuban/UI/classifier.py: Add docstrings.
368    
369            * Thuban/UI/dock.py: Add docstrings.
370    
371            * test/test_classgen.py: Use renamed Ramp instances.
372    
373    2003-07-30  Bernhard Herzog  <[email protected]>
374    
375            * Thuban/Lib/connector.py (QueueingPublisher): Removed. This class
376            was never used in Thuban.
377    
378    2003-07-30  Bernhard Herzog  <[email protected]>
379    
380            * Thuban/UI/join.py (JoinDialog.__init__): Use the table's Title()
381            method directly instead of going through the transient_table
382            method. This faster because transient_table may force the copy of
383            a DBF file into the transient database and setting a table's title
384            doesnm't affect the title of the associated transient table, so
385            this fixes RT #2042
386    
387            * Thuban/UI/main.py (__version__): Don't import the already
388            removed show_exception_dialog.
389    
390    2003-07-29  Jonathan Coles   <[email protected]>
391    
392            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
393            Put back this method and remove the equivalent function since we
394            are setting the exception hook from within this class (OnInit).

411    2003-07-29  Bernhard Herzog  <[email protected]>
412    
413            * Thuban/Model/data.py (SimpleStore): Removed. This class has been
414            deprecated since before the 0.8 release and isn't used in Thuban
415            itself anymore.
416    
417            * Thuban/Model/transientdb.py: Remove some unnecessary imports
418    
419    2003-07-29  Jonathan Coles   <[email protected]>
420    
421            * Thuban/UI/application.py (ThubanApplication.OnInit): set the
422            python exception hook here so that we are sure to catch any
423            Thuban exception that happen during initialization.
424    
425            * Thuban/UI/main.py (main): Don't set the exception hook here,
426            it will get set in ThubanApplication.OnInit.
427    
428    2003-07-29  Jonathan Coles   <[email protected]>
429                                                                                
430            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
431            Removed and called it show_exception_dialog() so that the exception
432            handler can be set before the class is created.
433

490    
491    2003-07-24  Bernhard Herzog  <[email protected]>
492    
493            * Thuban/Model/range.py, Thuban/version.py: Remove the #! line as
494            it annoys lintian which warns about these files not being
495            executable. The #1 isn't necessary here since if you absolutely
496            must execute them you can always say "python <filename>".
497    
498            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Remove
499            superfluous code to set brush and pen for point shapes

516            of the manual.
517    
518            * Thuban/UI/renderer.py (MapRenderer.render_map): Wrap method
519            with Begin/EndDrawing() calls to ensure we aren't doing to
520            many updates to the dc during rendering.
521            (ScreenRenderer.draw_shape_layer): self.draw_point_shape takes
522            a pen and brush argument so they need to be passed to the function.
523    
524            * Thuban/UI/viewport.py (ViewPort.calc_min_max_scales): New.
525            Calculates the minimum and maximum scale values. Factored out
526            of set_view_transform so that it could be used to zoom all the
527            way into a single point.
528            (ViewPort.set_view_transform): Call calc_min_max_scales().
529            (ViewPort.FitSelectedToWindow): Zoom to the maximum scale
530            if only a single point is selected.

563            MAP_REPLACED message it's no longer needed
564            (MainWindow.OpenSession, MainWindow.NewSession):
565            prepare_new_session has been removed.
566    
567            * Thuban/UI/classifier.py (Classifier.__init__): Subscribe to

581    
582            * test/test_viewport.py (SimpleViewPortTest.test_default_size):
583            Move this test from ViewPortTest.setUp to this new separate test
584            case. setUp is not the place for the actual tests.
585            (ViewPortTest.test_inital_settings, ViewPortTest.setUp): Move some
586            more of the test from setUp to the new test test_inital_settings.

600    
601    2003-07-18  Bernhard Herzog  <[email protected]>
602    
603            * test/runtests.py: The test suite can now be run without an X
604            connection. To make sure this remains true, remove the DISPLAY
605            environment variable so that an error occurs if the wxGTK is
606            imported accidentally
607    
608    2003-07-18  Bernhard Herzog  <[email protected]>
609

637            Rename to GetClassificationColumn.
638            (Layer.SetClassificationColumn, Layer.SetClassificationField):

677    
678            * test/test_classgen.py (TestFixedRamp.test): Extend test to check
679            the non-fixed values as well. The old test would have accepted a
680            fixed ramp that only returnes the fixed properties
681

683    
684            * Doc/manual/mainwindow.png, Doc/manual/mainwindow.xcf: Screen

692    
693            * Thuban/UI/mainwindow.py (MainWindow.ToggleLegend): Don't
694            fit the map to the window as this changes any zoom level that
695            the user may have set.
696    
697    2003-07-16  Jonathan Coles   <[email protected]>
698    
699            * Thuban/Model/classgen.py (generate_singletons,
700            generate_uniform_distribution, generate_quantiles): Remove
701            fixes parameter, but maintain the same functionality by having
702            the calling function pass a FixedRamp object for the ramp.
703            (FixedRamp): New. Adapts a ramp to have fixed property values.
704    
705            * Thuban/Model/classification.py: Use new CLASS_CHANGED message.

707            (Classification.__init__): Remove the layer parameter.
708            Classifications no longer need to have a parent layer.
709            (Classification.GetField, Classification.GetFieldType,
710            Classification.SetFieldInfo): Removed. The field name is stored
711            in the layer, and the type can be retreived by calling
712            Layer.GetFieldType().
713            (Classification._set_layer, Classification.GetLayer): Removed.
714            Classifications no longer have a parent layer.

719            we still have the old shape store to work with.
720            (Layer.GetClassificationField, Layer.SetClassificationField):
721            New. Method for getting/setting the field to classify on.
722            (Layer.SetClassification): Simplified now that the layer
723            simply has to hold a reference to the classification and not
724            tell the classification who owns it.
725            Fixes RTbug #2023.
726    
727            * Thuban/Model/load.py (SessionLoader.start_classification):
728            Set the field name on the layer, not the classification.
729

738    
739            * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Use a fixed
740            ramp when we need to fix certain values of a ramp rather than
741            using the old fixes parameter. Fixes RTbug #2024.
742    
743            * Thuban/UI/classifier.py (ClassGrid.CreateTable): Add fieldType
744            parameter.
745            (ClassTable.Reset): Add fieldType parameter and use it, rather
746            than asking the classification.
747            (Classifier.__init__): Remember the original class's field
748            and ask the layer for the field type, rather than the classification.
749            (Classifier.__SetGridTable): Retrieve the field and field type
750            for the table because they are not in the classification.
751            (Classifier._OnTry, Classifier._OnRevert): Set the classification
752            field on the layer in addition to the classification itself.
753    
754            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Get the
755            classification field from layer.

762    
763            * test/test_classification.py
764            (TestClassification.test_classification): Remove tests for methods
765            that no longer exist.
766    
767            * test/test_layer.py (SetShapeStoreTests.setUp): Classification
768            __init__ no longer has a field parameter, use SetClassificationField.
769            (SetShapeStoreTests.test_sanity): Use layer object to get class
770            field info.
771    
772            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Use
773            SetClassificationField on layer to set class field info.
774    
775            * test/test_viewport.py: Renamed from test/test_view.py.
776    
777    2003-07-16  Jan-Oliver Wagner <[email protected]>
778    
779            * Doc/manual/thuban-manual.xml: Added authors and an initial
780            coarse structure.
781    
782    2003-07-15  Bernhard Herzog  <[email protected]>
783    
784            * test/support.py (FloatComparisonMixin): This is a mix-in class
785            and therefore should not be derived from any other class.
786    
787            * test/test_range.py (RangeTest): FloatComparisonMixin is a
788            mix-in, so derive from TestCase as well.
789    
790    2003-07-15  Bernhard Herzog  <[email protected]>
791    
792            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Rework the
793            draw_func handling a bit to remove one layer of indirection. This
794            makes the renderer about 10% faster in the non-classifying case
795            and the code a bit cleaner
796            (MapRenderer.draw_point_shape): Add the pen and brush parameters
797            and set them in the dc. Now the draw_point_shape method and
798            wxproj's draw_polygon_shape function have basically the same
799            signature so that both can be directly used as draw_func
800    
801    2003-07-15  Bernhard Herzog  <[email protected]>
802    
803            * Thuban/Model/save.py (SessionSaver.write_classification): Encode
804            string values (in addition to the labels) as UTF 8
805    
806            * Thuban/Model/load.py (SessionLoader.start_clpoint): Decode the
807            values if the field type is string
808    
809            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Test
810            saving a session with non-ascii string classification values.
811    
812            * test/test_load.py (TestClassification.file_contents)
813            (TestClassification.test): Check for non-ascii values in string
814            classifications
815    
816    2003-07-14  Jonathan Coles   <[email protected]>
817    
818            * test/test_view.py: New. Tests for ViewPort.
819    
820    2003-07-14  Frank Koormann   <[email protected]>
821    
822            * Thuban/Model/load.py (SessionLoader.start_map): Encode map
823            title to latin1.  Fixes https://intevation.de/rt/webrt?serial_num=2013
824    
825            * test/test_load_0_8.py (TestUnicodeStrings): New, test load of

827            projection name.
828            
829    2003-07-10  Jonathan Coles   <[email protected]>
830    
831            * Thuban/UI/viewport.py (Tool.MouseUp): Should have called
832            drag_stop, not drag_move when the mouse is released.
833    
834    2003-07-10  Jonathan Coles   <[email protected]>
835    
836            The most important part of this is the seperation of view.py into
837            two pieces. viewport.py now has a class called ViewPort which
838            contains all the non-wx parts of view.py and can therefore be
839            tested. view.py contains only the wx-specific parts and is fairly
840            simple.
841    
842            * Thuban/UI/view.py: Stripped out all non-wx functionality. Fixes
843            RTTbug #1992.
844            * Thuban/UI/viewport.py: New. Contains non-wx view functionality.
845            RTTbug #1992.
846    
847            * Thuban/Model/classgen.py (generate_singletons,
848            generate_uniform_distribution, generate_quantiles):
849            Added 'fixes' parameter so that property attributes can
850            be held constant over the generated classification groups.
851            (CustomRamp.GetProperties): Remove unused variables.
852    
853            * Thuban/Model/map.py (Map.SetProjection): Send the old
854            projection as an argument to listeners of the MAP_PROJECTION_CHANGED
855            event.
856    
857            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Added 'records'
858            parameter which is a list of records that restricts which
859            records are saved. Fixes RTbug #1997.
860    
861            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
862            Port exception dialog from GREAT-ER. Fixes RTbug #1993.
863    
864            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Add controls
865            to allow the user to fix line color/width on generated groups.
866            (ClassGenDialog.OnOK): Use new 'fixes' parameter of the generate_*
867            functions to optionally fix group properties.
868    
869            * Thuban/UI/main.py (main): Set exception hook to the
870            ShowExceptionDialog. Fixes RTbug #1993.
871

876            Export Selection button and move the export buttons underneath
877            the table.
878            (QueryTableFrame.UpdateStatusText): Added event argument so
879            that it can respond to grid selection events. The status text
880            is now updated even when the table is not associated with a
881            layer as was previously assumed.
882            (QueryTableFrame.OnGridSelectRange, OnGridSelectCell): Removed.
883            UpdateStatusText responds to these events.
884            (QueryTableFrame.OnSaveAs): Renamed to doExport.
885            (QueryTableFrame.doExport): Helper function that saves the
886            entire table, or selected rows, to a file.
887            (QueryTableFrame.OnExport, QueryTableFrame.OnExportSel): New.
888            Respond to export button events and call doExport.
889    
890            * extensions/thuban/gdalwarp.cpp (ProjectRasterFile): Make sure
891            the function doesn't return NULL without first setting a Python
892            Error.
893    
894            * test/runtests.py (main): Only print "Unknown option" for
895            unsupported options.
896    
897            * test/support.py (FloatComparisonMixin.assertFloatEqual): Take
898            optional epsilon argument to specify floating point accuracy.
899            (FloatComparisonMixin.assertFloatSeqEqual): Call assertFloatEqual
900            for each item test.
901    
902            * test/test_csv_table.py (TestCSVTable.test_table_to_cvs): Add
903            tests for saving selected records.
904    
905            * test/test_dbf_table.py (TestTableToDBF.test_table_to_dbf): Add
906            tests for saving selected records.
907    
908            * test/test_map.py (TestMapWithContents.test_set_projection):
909            MAP_PROJECTION_CHANGED events send the old projection.
910    
911            * test/test_session.py
912            (TestSessionWithContent.test_forward_map_projection):
913            MAP_PROJECTION_CHANGED events send the old projection.
914    
915            * test/test_table.py (TableTest): Update tests to use non-deprecated
916            functions.
917    
918    2003-07-08  Bernhard Herzog  <[email protected]>
919    
920            * Thuban/Model/transientdb.py (TransientTableBase.Width): The type
921            constants in the column objects are the standard ones defined in
922            the table module.
923    
924            * test/test_transientdb.py
925            (TestTransientTable.test_transienttable_to_dbf): New. Test whether
926            exporting transient tables as DBF works. This should catch the bug
927            just fixed in TransientTableBase.Width.
928    
929    2003-07-08  Bernhard Herzog  <[email protected]>
930    
931            * Thuban/Model/classgen.py (CustomRamp.GetProperties): Compute the
932            interpolated colors correctly.
933    
934            * test/test_classgen.py (TestCustomRamp.test_color_interpolation):
935            New. Test case for the fix in classgen.py
936    
937    2003-07-08  Bernhard Herzog  <[email protected]>
938    
939            * test/runtests.py (main): Make the default output less verbose
940            and add a verbosity option (-v) to get the old output
941    
942    2003-07-08  Bernhard Herzog  <[email protected]>
943    
944            * Resources/XML/thuban-0.9.dtd: New. This will become the DTD for
945            0.9.
946    
947            * Thuban/Model/transientdb.py (TransientJoinedTable.JoinType):
948            New. Return the join type
949    
950            * Thuban/Model/save.py (SessionSaver.write_session): Use new 0.9
951            DTD
952            (SessionSaver.write_data_containers): Save the join type for
953            joined tables
954    
955            * Thuban/Model/load.py (SessionLoader.__init__): Add the new 0.9
956            namespace
957            (SessionLoader.start_jointable): Handle the jointype attribute
958    
959            * test/test_load_0_8.py: New. Effectively a copy of test_load.py
960            as of Thuban 0.8. These are now tests to determine whether Thuban
961            can still read files generated by Thuban 0.8
962    
963            * test/test_load.py (LoadSessionTest.dtd)
964            (TestSingleLayer.file_contents)

968            (TestJoinedTable.file_contents)
969            (TestLoadError.file_contents): Update for new DTD
970            (TestJoinedTable.file_contents, TestJoinedTable.setUp): Add test
971            for new join type attribute
972    
973            * test/test_save.py (SaveSessionTest.dtd)
974            (SaveSessionTest.testEmptySession)

987            function for table_to_dbf
988            (table_to_dbf): Deal with names longer than the 10 character limit
989    
990            * test/test_dbf_table.py (TestTableToDBF.test_table_to_dbf): Add
991            doc-string
992            (TestTableToDBF.test_table_to_dbf_long_col_names): New test for
993            long column names
994    
995    2003-07-03  Bernhard Herzog  <[email protected]>
996    
997            * Doc/manual/thuban-manual.xml: Fix the CVS Revision Tag syntax
998    
999    2003-07-03  Bernhard Herzog  <[email protected]>
1000    
1001            * Doc/manual/thuban-manual.xml, Doc/manual/README: New. Skeleton
1002            for the Thuban manual and README with some basic information about
1003            the manual
1004    
1005    2003-07-03  Bernhard Herzog  <[email protected]>
1006    
1007            * Thuban/Model/transientdb.py (TransientJoinedTable.__init__):
1008            Update doc-string
1009            (TransientJoinedTable.create): Do not modify the column objects of
1010            the input tables in place and copy all columns of the input tables
1011            into the joined table after all.
1012    
1013            * test/test_transientdb.py
1014            (TestTransientTable.test_transient_joined_table_same_column_name):
1015            Update to reflect the new behavior
1016            (TestTransientTable.test_transient_joined_table_with_equal_column_names):
1017            Update to reflect the new behavior
1018            (TestTransientTable.test_transient_joined_table_name_collisions_dont_modify_in_place):
1019            New test case for a bug which modified the column objects in place
1020    
1021    2003-07-02  Jonathan Coles   <[email protected]>
1022    
1023            * Thuban/Model/classgen.py (generate_singletons,
1024            generate_uniform_distribution, generate_quantiles,
1025            GenQuantiles0): Make sure maxValue isn't less than
1026            one, otherwise we could divide by zero.
1027    
1028            * test/test_classgen.py (ClassGenTest.doClassRangeTest,
1029            ClassGenTest.doClassSingleTest): Call doBoundsTest to
1030            check the end classification groups against the
1031            proper property values.
1032            (ClassGenTest.doBoundsTest): New. Checks the first and
1033            last classification groups to make sure their properties
1034            are the correct upper and lower bounds for a color ramp.
1035    
1036    2003-07-02  Jonathan Coles   <[email protected]>
1037    
1038            * Thuban/Model/classgen.py (generate_singletons,
1039            generate_uniform_distribution, generate_quantiles,
1040            GenQuantiles0): The denominator was one to high when
1041            calculating the index for the ramp causing the index
1042            to never to reach one.
1043    
1044    2003-07-02  Jonathan Coles   <[email protected]>
1045    
1046            Changed the singature of ClassGroupRange.__init__ and
1047            ClassGroupRange.SetRange() so that the min/max values are
1048            passed as a tuple. This makes a better calling scheme for
1049            when a Range object is passed instead.
1050    
1051            * Thuban/Model/classgen.py: Fixed parameters to
1052            ClassGroupRange constructor.
1053    
1054            * Thuban/Model/classification.py (ClassGroupRange.__init__):
1055            Consolidate the min/max parameters into a single _range which
1056            can either be a tuple or a Range object.
1057            (ClassGroupRange.SetRange): Consolidate the min/max parameters
1058            into a single _range which can either be a tuple or a Range object.
1059    
1060            * Thuban/Model/load.py (SessionLoader.start_clrange): Fix
1061            call to ClassGroupRange constructor to use a tuple.
1062    
1063            * Thuban/Model/layer.py (Layer.SetClassification): Switch
1064            the classification instance variable to the new class
1065            before calling _set_layer otherwise subscribers to a
1066            LAYER_CHANGED event will not see any difference.
1067    
1068            * test/test_classification.py: Fix tests of ClassGroupRange
1069            so that they use the new signature.
1070    
1071            * test/test_load.py: Fix use of ClassGroupRange so that it
1072            uses the new signature.
1073    
1074            * test/test_load_0_2.py: Fix use of ClassGroupRange so that it
1075            uses the new signature.
1076    
1077            * test/test_save.py: Fix use of ClassGroupRange so that it
1078            uses the new signature.
1079    
1080    
1081    2003-07-01  Jonathan Coles   <[email protected]>
1082    
1083            * Thuban/Model/classgen.py: Fixes RTbug #1972, 1971.
1084            Import used objects/class from color.
1085            (generate_singletons): We don't
1086            need the numGroups parameter anymore because we are using
1087            the new ramps with GetProperties().
1088            (generate_uniform_distribution): Use new ramp method
1089            GetProperties().
1090            (generate_quantiles, GenQuantiles0): Use new ramp method
1091            GetProperties().
1092            (CustomRamp.SetNumGroups): Removed. The ramps now map
1093            a value from 0 to 1 to class properties so the number
1094            of groups is not needed ahead of time.
1095            (CustomRamp.next): Removed. CustomRamp does not support
1096            interation anymore.
1097            (CustomRamp.GetProperties): Returns a ClassGroupProperties
1098            object based on the index value from 0 to 1 that is
1099            passed to it.
1100            (GreyRamp, RedRamp, GreenRamp, BlueRamp, GreenToRedRamp):
1101            Made into instances of Monochromatic class instread of
1102            deriving from it.
1103            (HotToCold.SetNumGroups): Removed. See CustomRamp.
1104            (HotToCold.next): Removed. See CustomRamp.
1105    
1106            * Thuban/Model/classification.py: Fixes RTbug #1973, 1971.
1107            (Classification.SetField, Classification.SetFieldType):
1108            Replaced with SetFieldInfo.
1109            (Classification.SetFieldInfo): New. Does a better job of
1110            what SetField and SetFieldType used to do by combining
1111            their function since they should really always be done
1112            at the same time.
1113            (Classification.SetLayer): Renamed to _set_layer.
1114            (Classification._set_layer): Should only be called from
1115            Layer's SetClassification. This does not cause a recursive
1116            call as SetLayer did because we know that Layer knows about
1117            the classification.
1118    
1119            * Thuban/Model/color.py: Fixes RTbug #1971.
1120            (_Transparent): Renamed from Transparent so it doesn't
1121            conflict with the module variable.
1122            (Transparent, Black): Renamed from Color.Transparent,
1123            Color.Black so they are not class variables.
1124    
1125            * Thuban/Model/layer.py: Fixes RTbug #1971, 1973.
1126            (Layer.Destroy): We don't need to call SetClassification
1127            anymore to clear out the back reference in the classifcation
1128            to the layer. It's better to set it to None using _set_layer,
1129            and we won't be creating another clas object too.
1130            (Layer.SetClassification): Classification._set_layer is not
1131            recursive so remove all the locking variables. Also clean
1132            up the code so that it remains unchanged if something fails.
1133    
1134            * Thuban/Model/load.py: Fixes RTbug #1971.
1135            (SessionLoader.start_classification): Call
1136            Classification.SetFieldInfo().
1137    
1138            * Thuban/Model/save.py: Removed import of Color which wasn't
1139            being used.
1140    
1141            * Thuban/UI/classgen.py: Fixes RTbug #1972.
1142            (ClassGenDialog.__init__): Color ramps are now instances
1143            already so we don't need to create any new objects.
1144            (ClassGenDialog.OnOK): Check for numGroups is no longer
1145            necessary because we never use it.
1146    
1147            * Thuban/UI/classifier.py: Fixes RTbug #1971.
1148            (Classifier.__BuildClassification, Classifier.__SetGridTable):
1149            Call Classification.SetFieldInfo() instead of SetFieldType.
1150    
1151            * Thuban/UI/renderer.py: Fixes RTbug #1971.
1152    
1153            * Thuban/UI/view.py: Fixes RTbug #1974, 1971.

1183            New. Test join of two tables with partly equal column names.
1184    
1185            * Thuban/Model/transientdb.py (TransientJoinedTable.create):
1186            If duplicates in left and right tables column names are found,
1187            append '_' (underscores) to the name until it is unique.
1188            Create always new internal names for the resulting table and reference
1189            columns in the join statement with <table>.<column>

1191    2003-07-01  Bernhard Herzog  <[email protected]>
1192    
1193            * test/test_transientdb.py
1194            (TestTransientTable.test_transient_joined_table_same_column_name):
1195            New. Test whether joining on columns with the same names in both
1196            tables works.
1197            
1198            * Thuban/Model/transientdb.py (TransientJoinedTable.create): Make
1199            sure to use the right internal names even when joining on field
1200            with the same names in both tables. Also, detect duplicate names
1201            in the joined table correctly.

1211            and splits it into a tuple of at most three integers.
1212            Used make_tuple() to make tuple versions of the version
1213            numbers.
1214    
1215            * Thuban/UI/about.py: Add Thuban email addresses.
1216    
1217    2003-06-30  Jonathan Coles   <[email protected]>
1218    
1219            * Thuban/version.py: SQLite/PySQLite version dependencies
1220            were too high.
1221    
1222    2003-06-30  Jonathan Coles   <[email protected]>
1223

1244            * Thuban/UI/classifier.py (Classifier.__EnableButtons):
1245            Reset the status of the buttons as the situation warrants,
1246            but in a better more reliable way by not relying on the
1247            current status to determine what needs to change.
1248    
1249            * Thuban/UI/main.py (wxCHECK_VERSION): Removed. Not needed.
1250            (verify_versions): Remove most of the code since it is

1266    2003-06-25  Jonathan Coles   <[email protected]>
1267    
1268            * Thuban/UI/classifier.py (Classifier.EditSymbol): The parent
1269            of the SelectPropertiesDialog should be self so the window
1270            appears on top.
1271            (ClassGroupPropertiesCtrl.DoEdit): The parent
1272            of the SelectPropertiesDialog should be self so the window

1295            * MANIFEST.in: Update with Resources/XML
1296    
1297            * setup.py: Don't include Locale resources yet as we don't
1298            have any and it causes problems building the distribution
1299            for Windows. Update version to 0.8.0.
1300    
1301            * Doc/thuban.dtd: Removed since it is now in Resources/XML.
1302    
1303            * Thuban/UI/mainwindow.py: Add blank line at the end because
1304            file was not being read correctly building the Windows
1305            distribution.
1306    
1307    2003-06-23  Jonathan Coles   <[email protected]>
1308    
1309            * Thuban/UI/mainwindow.py (MainWindow.About): Fix text.
1310    
1311            * Thuban/version.py: Temporarily update longversion for

1313    
1314    2003-06-23  Jonathan Coles   <[email protected]>
1315    
1316            * Thuban/UI/common.py (ThubanBeginBusyCursor): Call wxSafeYield
1317            to make sure that we don't create reentrant possibilities with
1318            wxYield.
1319    
1320            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxBeginBusyCursor()
1321            directly to avoid the wxSafeYield() call which generates an
1322            OnPaint event causing infinite recursion. Don't try to catch
1323            exception anymore. This was for before there were limits on map
1324            scaling.
1325    
1326    2003-06-23  Bernhard Herzog  <[email protected]>
1327    
1328            Bug fix for RT #1961:
1329    
1330            * Thuban/Model/load.py (SessionLoader.start_derivedshapesource):
1331            Register DerivedShapestores with the session
1332    
1333            * Thuban/Model/session.py (Session.Tables): Make sure each table
1334            is only listed once.
1335    
1336            * test/test_load.py (TestJoinedTable.test): Add check_format call.
1337            Update file contents to match the one written out.
1338    
1339    2003-06-20  Bernhard Herzog  <[email protected]>
1340    
1341            * test/xmlsupport.py (SaxEventLister.startElementNS)
1342            (SaxEventLister.endElementNS): Do not include the qname. Python
1343            2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
1344            is (presumably incorrectly) None, whereas it's a string with the
1345            element name in the later versions.
1346    
1347            * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
1348            (TestEventList.test_even_list_namespace): Update tests to reflect
1349            the new behaviour
1350            (TestEventList.test_even_list_id_normalization): Fix doc-string
1351    
1352    2003-06-20  Jonathan Coles   <[email protected]>
1353    
1354            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
1355            by deriving classes to determine if that layer supports shapes.
1356            (Layer): Override HasShapes and return true.
1357    
1358            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
1359            instead of a direct call to wx[Begin|End]CusyCursor().
1360            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
1361            table data.
1362    
1363            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
1364            New. Wrappers around the wxWindows functions that allow us to
1365            make additional calls such as wxYield which gives the native
1366            system a chance to update the cursor correctly.
1367    
1368            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
1369            instead of a direct call to wx[Begin|End]CusyCursor().
1370    
1371            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
1372            instead of a direct call to wx[Begin|End]CusyCursor().
1373            (MapCanvas.find_shape_at): Check if the current search layer
1374            support shapes, otherwise go on to the next layer.
1375    
1376            * test/test_layer.py: Add tests in each type of layer for
1377            HasClassification() and HasShapes()
1378

1380    
1381          * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after          * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
