2    
3            * Thuban/Model/layer.py: Remove the unused import of Shape from
4            data. It was only there for interface compatibility but it's not
5            used inside of Thuban and the generic Shape class will go away
6            soon anyway.
7    
8            * test/test_baserenderer.py (SimpleShape): Shape class for the
9            tests.
10            (SimpleShapeStore.Shape): Use SimpleShape instead of
11            Thuban.Model.data.Shape to make the tests independed of the coming
12            changes.
13    
14    2003-08-07  Bernhard Herzog  <[email protected]>
15    
16            * test/support.py (SkipTest, ThubanTestResult, ThubanTestRunner)
17            (ThubanTestProgram): New classes that extend the respective
18            classes from unittest. These new version support skipping tests
19            under certain expected conditions. In the Thuban test suite we
20            uses this for tests that require the optional gdal support.
21            (run_tests): Use ThubanTestProgram instead of the unittest.main()
22    
23            * test/runtests.py (main): Use the new ThubanTestRunner instead of
24            the normal one from unittest
25    
26            * test/test_layer.py (TestLayer.test_raster_layer): If this test
27            is not run because gdal support isn't available report this to the
28            runner.
29    
30            * test/test_baserenderer.py
31            (TestBaseRenderer.test_raster_no_projection): Do not run this test
32            if gdal support isn't available and report this to the runner.
33    
34    2003-08-06  Bernhard Herzog  <[email protected]>
35    
36            Rearrange the renderers a bit, partly in preparation for changes
37            required for the postgis merge, partly to make it more testable.
38            Also make the representation of coordinates in Shapes more
39            consistent.
40    
41            * Thuban/UI/renderer.py (MapRenderer): Most of the code/methods in
42            this class is now in BaseRenderer. This class is now practically
43            only a specialization of BaseRenderer for rendering to an actual
44            wx DC.
45            (ScreenRenderer.draw_shape_layer): Use self.low_level_renderer()
46            to get the shapetype specific rendering functions.
47    
48            * Thuban/UI/baserenderer.py: New file with the basic rendering
49            logic. The code in this file is completely independend of wx.
50            (BaseRenderer): Class with the basic rendering logic
51    
52            * test/test_baserenderer.py: New. Test cases for BaseRenderer
53    
54            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
55            error_on_redraw to guard agains endless loops and stack overflows
56            when there's a bug in the rendering code that raises exceptions.
57            (MapCanvas.OnIdle, MapCanvas._do_redraw): Split the actual
58            rendering into a separate method _do_redraw so that error handling
59            is a bit easier. When an exception occurs, set error_on_redraw to
60            true. When it's true on entry to OnIdle do nothing and return
61            immediately.
62    
63            * Thuban/Model/data.py (ShapefileStore.Shape): For consistency, a
64            Shape object will always have the coordinates as a list of list of
65            coordinate pairs (tuples).
66            (Shape.compute_bbox): Adapt to new representation.
67    
68            * Thuban/UI/viewport.py (ViewPort.find_shape_at)
69            (ViewPort.LabelShapeAt): Adapt to new coordinate representation in
70            Shape objects.
71    
72            * test/test_shapefilestore.py
73            (ShapefileStoreTests.assertFloatTuplesEqual)
74            (ShapefileStoreTests.assertPointListEquals): Rename to
75            assertPointListEquals and change purpose to checking equality of
76            the lists returned by Shape.Points().
77            (TestShapefileStoreArc.test_shape)
78            (TestShapefileStorePolygon.test_shape)
79            (TestShapefileStorePoint.test_shape): Use the new
80            assertPointListEquals instead of assertFloatTuplesEqual
81    
82            * test/test_layer.py (TestLayer.assertFloatTuplesEqual)
83            (TestLayer.assertPointListEquals): Rename to assertPointListEquals
84            and change purpose to checking equality of the lists returned by
85            Shape.Points().
86            (TestLayer.test_arc_layer, TestLayer.test_arc_layer)
87            (TestLayer.test_polygon_layer, TestLayer.test_point_layer)
88            (TestLayer.test_derived_store): Use the new assertPointListEquals
89            instead of assertFloatTuplesEqual
90    
91            * test/test_derivedshapestore.py
92            (TestDerivedShapeStore.assertFloatTuplesEqual)
93            (TestDerivedShapeStore.assertPointListEquals): Rename to
94            assertPointListEquals and change purpose to checking equality of
95            the lists returned by Shape.Points().
96            (TestDerivedShapeStore.test_shape): Use the new
97            assertPointListEquals instead of assertFloatTuplesEqual
98    
99    2003-08-06  Jan-Oliver Wagner <[email protected]>
100    
101            * Thuban/UI/projdialog.py (UTMPanel._OnPropose): Added test for
102            a bounding box. A dialog is raised in case, no bounding box
103            is found. This fixes bug #2043:
104            https://intevation.de/rt/webrt?serial_num=2043
105    
106    2003-08-05  Bernhard Herzog  <[email protected]>
107    
108            * Thuban/Model/color.py (Color.__repr__): Make the repr of a color
109            object look like a Color instantiation. Formerly it looked like a
110            tuple.
111    
112            * test/test_color.py (TestColor.test_repr)
113            (TestColor.test_equality, TestColor.test_inequality): New. test
114            some more apects of the Color class
115            (TestTransparent.test_repr, TestTransparent.test_hex)
116            (TestTransparent.test_equality): New. Test cases for the
117            Transparent object.
118    
119    2003-08-04  Jan-Oliver Wagner <[email protected]>
120    
121            * Doc/manual/thuban-manual.xml: a number of small improvements.
122            The resulting file is the version submitted for GREAT-ER II.
123    
124    2003-08-01  Bernhard Herzog  <[email protected]>
125    
126            * Thuban/UI/resource.py, Thuban/UI/projdialog.py,
127            Thuban/UI/join.py, Thuban/UI/classgen.py, Thuban/UI/about.py,
128            Thuban/Model/resource.py: Insert cvs keywords and doc-strings.
129    
130            * Thuban/UI/common.py: Insert cvs keywords and doc-strings.
131            (Color2wxColour, wxColour2Color, ThubanBeginBusyCursor)
132            (ThubanEndBusyCursor): Add doc-strings
133    
134    2003-08-01  Bernhard Herzog  <[email protected]>
135    
136            First step towards PostGIS integration. More abstraction by movin
137            more code from the layer to the shapestore. More methods of the
138            layer are now simply delegated to the equivalent method of the
139            shapestore. The SHAPETYPE_* constants are now in data not in
140            layer.
141    
142            * Thuban/Model/data.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
143            (SHAPETYPE_POINT, Shape): Move these constants and classes from
144            layer.py to data.py
145            (ShapefileStore.__init__): More Initialization for the new methods
146            and functionality.
147            (ShapefileStore.ShapeType, ShapefileStore.NumShapes)
148            (ShapefileStore.BoundingBox, ShapefileStore.ShapesInRegion)
149            (ShapefileStore.Shape): New methods that were formerly implemented
150            in the layer.
151            (DerivedShapeStore.Shape, DerivedShapeStore.ShapesInRegion)
152            (DerivedShapeStore.ShapeType, DerivedShapeStore.NumShapes)
153            (DerivedShapeStore.BoundingBox): New. DerivedShapeStore
154            equivalents of the new shape methods. These versions are simply
155            delegated to the original shapstore.
156    
157            * Thuban/Model/layer.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
158            (SHAPETYPE_POINT, Shape): Removed. They're now in data.py
159            (Layer.SetShapeStore): Removed the initializatin of instance
160            variables that were needed for the stuff that's now in
161            ShapefileStore
162            (Layer.BoundingBox, Layer.NumShapes, Layer.ShapeType)
163            (Layer.Shape, Layer.ShapesInRegion): Simply delegate to the
164            shapestore.
165    
166            * Thuban/UI/classifier.py, Thuban/UI/renderer.py,
167            Thuban/UI/viewport.py: Import the SHAPETYPE_* constants from data
168            instead of layer.
169    
170            * test/test_shapefilestore.py: New. Tests for ShapefileStore.
171    
172            * test/test_derivedshapestore.py: New. Tests for DerivedShapeStore.
173    
174            * test/test_layer.py: Import the SHAPETYPE_* constants from data
175            instead of layer.
176            (TestLayer.test_derived_store): Remove the test for the exception
177            when instantiating the DerivedShapeStore with an incompatible
178            table which is now in test_derivedshapestore.py. Add some more
179            tests of the layer methods to determine whether they work for a
180            DerivedShapeStore as well.
181    
182    2003-07-31  Jonathan Coles   <[email protected]>
183    
184            * Doc/manual/thuban-manual.xml: Fix the list of required packages
185            by just listing the name and where they can be found.
186    
187    2003-07-31  Frank Koormann   <[email protected]>
188    
189            * Doc/manual/thuban-manual.xml:
190            Changed the screenshot elements to figure.
191            Changed some variablelist elements to itemizedlist.
192            Added section on GDAL formats.
193    
194    2003-07-31  Jonathan Coles   <[email protected]>
195    
196            * Doc/manual/thuban-manual.xml: Added a few sentences about
197            the Fix Border Color option when generating classes.
198    
199    2003-07-30  Jonathan Coles   <[email protected]>
200    
201            * Thuban/Model/classgen.py: Add docstrings. Rename specific
202            Ramp instances to use lower_case_style.
203    
204            * Thuban/UI/classgen.py: Use renamed Ramp instances.
205            
206            * Thuban/UI/classifier.py: Add docstrings.
207    
208            * Thuban/UI/dock.py: Add docstrings.
209    
210            * test/test_classgen.py: Use renamed Ramp instances.
211    
212    2003-07-30  Bernhard Herzog  <[email protected]>
213    
214            * Thuban/Lib/connector.py (QueueingPublisher): Removed. This class
215            was never used in Thuban.
216    
217    2003-07-30  Bernhard Herzog  <[email protected]>
218    
219            * Thuban/UI/join.py (JoinDialog.__init__): Use the table's Title()
220            method directly instead of going through the transient_table
221            method. This faster because transient_table may force the copy of
222            a DBF file into the transient database and setting a table's title
223            doesnm't affect the title of the associated transient table, so
224            this fixes RT #2042
225    
226            * Thuban/UI/main.py (__version__): Don't import the already
227            removed show_exception_dialog.
228    
229    2003-07-29  Jonathan Coles   <[email protected]>
230    
231            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
232            Put back this method and remove the equivalent function since we
233            are setting the exception hook from within this class (OnInit).
234    
235    2003-07-29  Jonathan Coles   <[email protected]>
236    
237            * Doc/manual/images/5_2_custom_ramp.png,
238            Doc/manual/images/5_2_quantiles.png,
239            Doc/manual/images/5_2_uniform_dist.png,
240            Doc/manual/images/5_2_unique_values.png,
241            Doc/manual/images/8_int_error.png: New screen shots.
242    
243            * Doc/manual/thuban-manual.xml: Fixed typos and wording, clarified
244            some points, and added more screen shots.
245    
246    2003-07-29  Bernhard Herzog  <[email protected]>
247    
248            * Thuban/Model/data.py: Remove the now unused import of warnings
249    
250    2003-07-29  Bernhard Herzog  <[email protected]>
251    
252            * Thuban/Model/data.py (SimpleStore): Removed. This class has been
253            deprecated since before the 0.8 release and isn't used in Thuban
254            itself anymore.
255    
256            * Thuban/Model/transientdb.py: Remove some unnecessary imports
257    
258    2003-07-29  Jonathan Coles   <[email protected]>
259    
260            * Thuban/UI/application.py (ThubanApplication.OnInit): set the
261            python exception hook here so that we are sure to catch any
262            Thuban exception that happen during initialization.
263    
264            * Thuban/UI/main.py (main): Don't set the exception hook here,
265            it will get set in ThubanApplication.OnInit.
266    
267    2003-07-29  Jonathan Coles   <[email protected]>
268                                                                                
269            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
270            Removed and called it show_exception_dialog() so that the exception
271            handler can be set before the class is created.
272                                                                                
273            * Thuban/UI/main.py (main): Install the exception handler before
274            a ThubanApplication is created.
275

330    2003-07-24  Bernhard Herzog  <[email protected]>
331    
332            * Thuban/Model/range.py, Thuban/version.py: Remove the #! line as
333            it annoys lintian which warns about these files not being
334            executable. The #1 isn't necessary here since if you absolutely
335            must execute them you can always say "python <filename>".
336    
337            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Remove
338            superfluous code to set brush and pen for point shapes
339    
340            * Thuban/UI/viewport.py: Remove commented out code that wouldn't
341            belong in viewport anyway
342

350            correctly.
351    
352    2003-07-22  Jonathan Coles   <[email protected]>
353    
354            * Doc/manual/thuban-manual.xml: Continue to write first revision
355            of the manual.
356    
357            * Thuban/UI/renderer.py (MapRenderer.render_map): Wrap method
358            with Begin/EndDrawing() calls to ensure we aren't doing to
359            many updates to the dc during rendering.
360            (ScreenRenderer.draw_shape_layer): self.draw_point_shape takes
361            a pen and brush argument so they need to be passed to the function.
362    
363            * Thuban/UI/viewport.py (ViewPort.calc_min_max_scales): New.
364            Calculates the minimum and maximum scale values. Factored out
365            of set_view_transform so that it could be used to zoom all the
366            way into a single point.
367            (ViewPort.set_view_transform): Call calc_min_max_scales().
368            (ViewPort.FitSelectedToWindow): Zoom to the maximum scale
369            if only a single point is selected.
370

400            Delegate MAP_REPLACED to the canvas too
401            (MainWindow.prepare_new_session): Removed. Thanks to the new
402            MAP_REPLACED message it's no longer needed
403            (MainWindow.OpenSession, MainWindow.NewSession):
404            prepare_new_session has been removed.
405    
406            * Thuban/UI/classifier.py (Classifier.__init__): Subscribe to
407            MAP_REPLACED so that we can close the dialog if a new map is set.
408            (Classifier.unsubscribe_messages): Unsubscribe from MAP_REPLACED
409            (Classifier.map_replaced): Handle MAP_REPLACED by closing the
410            dialog

415            tests. Subscribe to MAP_REPLACED messages too.
416            (ViewPortTest.tearDown): No need to explicitly unsubscribe
417            (ViewPortTest.test_set_map): New test for the SetMap method.
418    
419    2003-07-18  Bernhard Herzog  <[email protected]>
420    
421            * test/test_viewport.py (SimpleViewPortTest.test_default_size):
422            Move this test from ViewPortTest.setUp to this new separate test
423            case. setUp is not the place for the actual tests.
424            (ViewPortTest.test_inital_settings, ViewPortTest.setUp): Move some
425            more of the test from setUp to the new test test_inital_settings.
426            (ViewPortTest.test_win_to_proj, ViewPortTest.test_proj_to_win)
427            (ViewPortTest.test_proj_conv): Split test_proj_conv into
428            test_win_to_proj and test_proj_to_win and make the tests easier to
429            understand
430            (ViewPortTest.testFitRectToWindow, ViewPortTest.testZoomFactor)
431            (ViewPortTest.testZoomOutToRect, ViewPortTest.testTranslate)

439    
440    2003-07-18  Bernhard Herzog  <[email protected]>
441    
442            * test/runtests.py: The test suite can now be run without an X
443            connection. To make sure this remains true, remove the DISPLAY
444            environment variable so that an error occurs if the wxGTK is
445            imported accidentally
446    
447    2003-07-18  Bernhard Herzog  <[email protected]>
448    
449            * Thuban/UI/viewport.py: Remove unused imports
450    
451            * Thuban/UI/view.py: Remove unused imports

453    2003-07-18  Bernhard Herzog  <[email protected]>
454    
455            * test/test_export.py Remove unused imports. The OutputTransform
456            function is now in viewport.py and is called output_transform
457            (TestScalebar.test_output_transform)
458            (TestScalebar.test_OutputTransform): Renamed to
459            test_output_transform and updated to use output_transform instead
460            of OutputTransform
461    
462            * Thuban/UI/view.py (OutputTransform): Moved to viewport.py and
463            renamed.
464            (MapCanvas.Export, MapPrintout.draw_on_dc): OutputTransform was
465            renamed to output_transform
466    
467            * Thuban/UI/viewport.py (OutputTransform, output_transform):
468            Rename to output_transform
469

471    
472            * Thuban/Model/layer.py (Layer.__init__): Rename
473            classificationField to classificatin_column and init it here so
474            that it can be used in SetClassificationColumn
475            (Layer.GetClassificationColumn, Layer.GetClassificationField):
476            Rename to GetClassificationColumn.
477            (Layer.SetClassificationColumn, Layer.SetClassificationField):
478            Rename to SetClassificationColumn and issue a LAYER_CHANGED
479            message if the column changes.
480            (Layer._classification_changed, Layer.ClassChanged): Rename to
481            _classification_changed. Update the callers.
482            (Layer.SetShapeStore): Further field->column renames.
483    
484            * Thuban/Model/load.py (SessionLoader.start_classification)
485            (SessionLoader.start_clpoint): Updates because of
486            field->column method name changes in the Layer class
487    
488            * Thuban/Model/save.py (SessionSaver.write_classification): Updates
489            because of field->column method name changes in the Layer class
490    
491            * Thuban/UI/classifier.py (Classifier.__init__)
492            (Classifier._OnTry, Classifier._OnRevert): Updates because of

496            because of field->column method name changes in the Layer class
497    
498            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Updates because
499            of field->column method name changes in the Layer class
500    
501            * test/test_save.py (SaveSessionTest.testClassifiedLayer)
502            (SaveSessionTest.testClassifiedLayer): Update because of
503            field->column method name changes in the Layer class
504    
505            * test/test_layer.py (SetShapeStoreTests.setUp)
506            (SetShapeStoreTests.test_sanity): Update because of field->column
507            method name changes in the Layer class
508            (TestLayerModification.setUp): Subscribe to LAYER_CHANGED as well
509            (TestLayerModification.test_sanity)
510            (TestLayerModification.test_initial_settings): remove unsued code
511            and rename to test_sanity.
512            (TestLayerModification.test_set_classification): New test for
513            SetClassification and SetClassificationField.
514    
515    2003-07-18  Bernhard Herzog  <[email protected]>
516    
517            * test/test_classgen.py (TestFixedRamp.test): Extend test to check
518            the non-fixed values as well. The old test would have accepted a
519            fixed ramp that only returnes the fixed properties
520    
521    2003-07-17  Jonathan Coles   <[email protected]>
522    
523            * Doc/manual/mainwindow.png, Doc/manual/mainwindow.xcf: Screen
524            shots for the manual. The XCF file is the source image and
525            has additional layers to support changes.
526    
527            * Doc/manual/thuban-manual.xml: Wrote an initial Introduction.
528    
529            * Thuban/UI/classifier.py (Classifier.__BuildClassification):
530            Return both the new class and the field name.
531    
532            * Thuban/UI/mainwindow.py (MainWindow.ToggleLegend): Don't
533            fit the map to the window as this changes any zoom level that
534            the user may have set.
535    
536    2003-07-16  Jonathan Coles   <[email protected]>
537    
538            * Thuban/Model/classgen.py (generate_singletons,
539            generate_uniform_distribution, generate_quantiles): Remove
540            fixes parameter, but maintain the same functionality by having
541            the calling function pass a FixedRamp object for the ramp.
542            (FixedRamp): New. Adapts a ramp to have fixed property values.
543    
544            * Thuban/Model/classification.py: Use new CLASS_CHANGED message.
545            (Classification): Inherit from Publisher.
546            (Classification.__init__): Remove the layer parameter.
547            Classifications no longer need to have a parent layer.
548            (Classification.GetField, Classification.GetFieldType,
549            Classification.SetFieldInfo): Removed. The field name is stored
550            in the layer, and the type can be retreived by calling
551            Layer.GetFieldType().
552            (Classification._set_layer, Classification.GetLayer): Removed.
553            Classifications no longer have a parent layer.
554    
555            * Thuban/Model/layer.py (Layer.Destroy): Unsubscribe from the
556            classification.
557            (Layer.SetShapeStore): Reset the classification first while
558            we still have the old shape store to work with.
559            (Layer.GetClassificationField, Layer.SetClassificationField):
560            New. Method for getting/setting the field to classify on.
561            (Layer.SetClassification): Simplified now that the layer
562            simply has to hold a reference to the classification and not
563            tell the classification who owns it.
564            Fixes RTbug #2023.
565    
566            * Thuban/Model/load.py (SessionLoader.start_classification):
567            Set the field name on the layer, not the classification.
568    
569            * Thuban/Model/messages.py: Add CLASS_CHANGED for when a
570            classification is modified.
571    
572            * Thuban/Model/save.py (SessionSaver.write_classification):
573            Get the field name and type from the layer.
574    
575            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Renamed
576            parameter records to rows and add docstring. Fixes RTbug #1997.
577    
578            * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Use a fixed
579            ramp when we need to fix certain values of a ramp rather than
580            using the old fixes parameter. Fixes RTbug #2024.
581    
582            * Thuban/UI/classifier.py (ClassGrid.CreateTable): Add fieldType
583            parameter.
584            (ClassTable.Reset): Add fieldType parameter and use it, rather
585            than asking the classification.
586            (Classifier.__init__): Remember the original class's field
587            and ask the layer for the field type, rather than the classification.
588            (Classifier.__SetGridTable): Retrieve the field and field type
589            for the table because they are not in the classification.
590            (Classifier._OnTry, Classifier._OnRevert): Set the classification
591            field on the layer in addition to the classification itself.
592    
593            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Get the
594            classification field from layer.
595    
596            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Get the
597            classification field from layer. Split up tests and remove
598            *-imports. Fixes RTbug #1992.
599    
600            * test/test_classgen.py (TestFixedRamp): Test for the FixedRamp class.
601    
602            * test/test_classification.py
603            (TestClassification.test_classification): Remove tests for methods
604            that no longer exist.
605    
606            * test/test_layer.py (SetShapeStoreTests.setUp): Classification
607            __init__ no longer has a field parameter, use SetClassificationField.
608            (SetShapeStoreTests.test_sanity): Use layer object to get class
609            field info.
610    
611            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Use
612            SetClassificationField on layer to set class field info.
613    
614            * test/test_viewport.py: Renamed from test/test_view.py.
615    
616    2003-07-16  Jan-Oliver Wagner <[email protected]>
617    
618            * Doc/manual/thuban-manual.xml: Added authors and an initial
619            coarse structure.
620    
621    2003-07-15  Bernhard Herzog  <[email protected]>
622    
623            * test/support.py (FloatComparisonMixin): This is a mix-in class
624            and therefore should not be derived from any other class.
625    
626            * test/test_range.py (RangeTest): FloatComparisonMixin is a
627            mix-in, so derive from TestCase as well.
628    
629    2003-07-15  Bernhard Herzog  <[email protected]>
630    
631            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Rework the
632            draw_func handling a bit to remove one layer of indirection. This
633            makes the renderer about 10% faster in the non-classifying case
634            and the code a bit cleaner
635            (MapRenderer.draw_point_shape): Add the pen and brush parameters
636            and set them in the dc. Now the draw_point_shape method and
637            wxproj's draw_polygon_shape function have basically the same
638            signature so that both can be directly used as draw_func
639    
640    2003-07-15  Bernhard Herzog  <[email protected]>
641    
642            * Thuban/Model/save.py (SessionSaver.write_classification): Encode
643            string values (in addition to the labels) as UTF 8
644    
645            * Thuban/Model/load.py (SessionLoader.start_clpoint): Decode the
646            values if the field type is string
647    
648            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Test
649            saving a session with non-ascii string classification values.
650    
651            * test/test_load.py (TestClassification.file_contents)
652            (TestClassification.test): Check for non-ascii values in string
653            classifications
654    
655    2003-07-14  Jonathan Coles   <[email protected]>
656    
657            * test/test_view.py: New. Tests for ViewPort.
658    
659    2003-07-14  Frank Koormann   <[email protected]>
660    
661            * Thuban/Model/load.py (SessionLoader.start_map): Encode map
662            title to latin1.  Fixes https://intevation.de/rt/webrt?serial_num=2013
663    
664            * test/test_load_0_8.py (TestUnicodeStrings): New, test load of
665            unicode strings from session file: session title, map title and
666            projection name.
667            
668    2003-07-10  Jonathan Coles   <[email protected]>
669    
670            * Thuban/UI/viewport.py (Tool.MouseUp): Should have called
671            drag_stop, not drag_move when the mouse is released.
672    
673    2003-07-10  Jonathan Coles   <[email protected]>
674    
675            The most important part of this is the seperation of view.py into
676            two pieces. viewport.py now has a class called ViewPort which
677            contains all the non-wx parts of view.py and can therefore be
678            tested. view.py contains only the wx-specific parts and is fairly
679            simple.
680    
681            * Thuban/UI/view.py: Stripped out all non-wx functionality. Fixes
682            RTTbug #1992.
683            * Thuban/UI/viewport.py: New. Contains non-wx view functionality.
684            RTTbug #1992.
685    
686            * Thuban/Model/classgen.py (generate_singletons,
687            generate_uniform_distribution, generate_quantiles):
688            Added 'fixes' parameter so that property attributes can
689            be held constant over the generated classification groups.
690            (CustomRamp.GetProperties): Remove unused variables.
691    
692            * Thuban/Model/map.py (Map.SetProjection): Send the old
693            projection as an argument to listeners of the MAP_PROJECTION_CHANGED
694            event.
695    
696            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Added 'records'
697            parameter which is a list of records that restricts which
698            records are saved. Fixes RTbug #1997.
699    
700            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
701            Port exception dialog from GREAT-ER. Fixes RTbug #1993.
702    
703            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Add controls
704            to allow the user to fix line color/width on generated groups.
705            (ClassGenDialog.OnOK): Use new 'fixes' parameter of the generate_*
706            functions to optionally fix group properties.
707    
708            * Thuban/UI/main.py (main): Set exception hook to the
709            ShowExceptionDialog. Fixes RTbug #1993.
710    
711            * Thuban/UI/mainwindow.py (MainWindow.ShowTableView): Raise
712            the table window when it is selectd to be shown.
713    
714            * Thuban/UI/tableview.py (QueryTableFrame.__init__): Add an
715            Export Selection button and move the export buttons underneath
716            the table.
717            (QueryTableFrame.UpdateStatusText): Added event argument so
718            that it can respond to grid selection events. The status text
719            is now updated even when the table is not associated with a
720            layer as was previously assumed.
721            (QueryTableFrame.OnGridSelectRange, OnGridSelectCell): Removed.
722            UpdateStatusText responds to these events.
723            (QueryTableFrame.OnSaveAs): Renamed to doExport.
724            (QueryTableFrame.doExport): Helper function that saves the
725            entire table, or selected rows, to a file.
726            (QueryTableFrame.OnExport, QueryTableFrame.OnExportSel): New.
727            Respond to export button events and call doExport.
728    
729            * extensions/thuban/gdalwarp.cpp (ProjectRasterFile): Make sure
730            the function doesn't return NULL without first setting a Python
731            Error.
732    
733            * test/runtests.py (main): Only print "Unknown option" for
734            unsupported options.
735    
736            * test/support.py (FloatComparisonMixin.assertFloatEqual): Take
737            optional epsilon argument to specify floating point accuracy.
738            (FloatComparisonMixin.assertFloatSeqEqual): Call assertFloatEqual
739            for each item test.
740    
741            * test/test_csv_table.py (TestCSVTable.test_table_to_cvs): Add
742            tests for saving selected records.
743    
744            * test/test_dbf_table.py (TestTableToDBF.test_table_to_dbf): Add
745            tests for saving selected records.
746    
747            * test/test_map.py (TestMapWithContents.test_set_projection):
748            MAP_PROJECTION_CHANGED events send the old projection.
749    
750            * test/test_session.py
751            (TestSessionWithContent.test_forward_map_projection):
752            MAP_PROJECTION_CHANGED events send the old projection.
753    
754            * test/test_table.py (TableTest): Update tests to use non-deprecated
755            functions.
756    
757    2003-07-08  Bernhard Herzog  <[email protected]>
758    
759            * Thuban/Model/transientdb.py (TransientTableBase.Width): The type
760            constants in the column objects are the standard ones defined in
761            the table module.
762    
763            * test/test_transientdb.py
764            (TestTransientTable.test_transienttable_to_dbf): New. Test whether
765            exporting transient tables as DBF works. This should catch the bug

801    
802            * test/test_load.py (LoadSessionTest.dtd)

845    
846            * Thuban/Model/transientdb.py (TransientJoinedTable.__init__):
847            Update doc-string
848            (TransientJoinedTable.create): Do not modify the column objects of
849            the input tables in place and copy all columns of the input tables
850            into the joined table after all.
851    
852            * test/test_transientdb.py
853            (TestTransientTable.test_transient_joined_table_same_column_name):

858            New test case for a bug which modified the column objects in place
859    
860    2003-07-02  Jonathan Coles   <[email protected]>
861    
862            * Thuban/Model/classgen.py (generate_singletons,
863            generate_uniform_distribution, generate_quantiles,
864            GenQuantiles0): Make sure maxValue isn't less than
865            one, otherwise we could divide by zero.
866    
867            * test/test_classgen.py (ClassGenTest.doClassRangeTest,
868            ClassGenTest.doClassSingleTest): Call doBoundsTest to
869            check the end classification groups against the
870            proper property values.
871            (ClassGenTest.doBoundsTest): New. Checks the first and
872            last classification groups to make sure their properties
873            are the correct upper and lower bounds for a color ramp.
874    
875    2003-07-02  Jonathan Coles   <[email protected]>
876    
877            * Thuban/Model/classgen.py (generate_singletons,
878            generate_uniform_distribution, generate_quantiles,
879            GenQuantiles0): The denominator was one to high when
880            calculating the index for the ramp causing the index
881            to never to reach one.
882    
883    2003-07-02  Jonathan Coles   <[email protected]>
884    
885            Changed the singature of ClassGroupRange.__init__ and
886            ClassGroupRange.SetRange() so that the min/max values are
887            passed as a tuple. This makes a better calling scheme for
888            when a Range object is passed instead.
889    
890            * Thuban/Model/classgen.py: Fixed parameters to
891            ClassGroupRange constructor.
892    
893            * Thuban/Model/classification.py (ClassGroupRange.__init__):
894            Consolidate the min/max parameters into a single _range which
895            can either be a tuple or a Range object.
896            (ClassGroupRange.SetRange): Consolidate the min/max parameters
897            into a single _range which can either be a tuple or a Range object.
898    
899            * Thuban/Model/load.py (SessionLoader.start_clrange): Fix
900            call to ClassGroupRange constructor to use a tuple.
901    
902            * Thuban/Model/layer.py (Layer.SetClassification): Switch
903            the classification instance variable to the new class
904            before calling _set_layer otherwise subscribers to a
905            LAYER_CHANGED event will not see any difference.
906    
907            * test/test_classification.py: Fix tests of ClassGroupRange
908            so that they use the new signature.
909    
910            * test/test_load.py: Fix use of ClassGroupRange so that it
911            uses the new signature.
912    
913            * test/test_load_0_2.py: Fix use of ClassGroupRange so that it
914            uses the new signature.
915    
916            * test/test_save.py: Fix use of ClassGroupRange so that it
917            uses the new signature.
918    
919    
920    2003-07-01  Jonathan Coles   <[email protected]>
921    
922            * Thuban/Model/classgen.py: Fixes RTbug #1972, 1971.
923            Import used objects/class from color.
924            (generate_singletons): We don't
925            need the numGroups parameter anymore because we are using
926            the new ramps with GetProperties().
927            (generate_uniform_distribution): Use new ramp method
928            GetProperties().
929            (generate_quantiles, GenQuantiles0): Use new ramp method
930            GetProperties().
931            (CustomRamp.SetNumGroups): Removed. The ramps now map
932            a value from 0 to 1 to class properties so the number
933            of groups is not needed ahead of time.
934            (CustomRamp.next): Removed. CustomRamp does not support
935            interation anymore.
936            (CustomRamp.GetProperties): Returns a ClassGroupProperties
937            object based on the index value from 0 to 1 that is
938            passed to it.
939            (GreyRamp, RedRamp, GreenRamp, BlueRamp, GreenToRedRamp):
940            Made into instances of Monochromatic class instread of
941            deriving from it.
942            (HotToCold.SetNumGroups): Removed. See CustomRamp.
943            (HotToCold.next): Removed. See CustomRamp.
944    
945            * Thuban/Model/classification.py: Fixes RTbug #1973, 1971.
946            (Classification.SetField, Classification.SetFieldType):
947            Replaced with SetFieldInfo.
948            (Classification.SetFieldInfo): New. Does a better job of
949            what SetField and SetFieldType used to do by combining
950            their function since they should really always be done
951            at the same time.
952            (Classification.SetLayer): Renamed to _set_layer.
953            (Classification._set_layer): Should only be called from
954            Layer's SetClassification. This does not cause a recursive
955            call as SetLayer did because we know that Layer knows about
956            the classification.
957    
958            * Thuban/Model/color.py: Fixes RTbug #1971.
959            (_Transparent): Renamed from Transparent so it doesn't
960            conflict with the module variable.
961            (Transparent, Black): Renamed from Color.Transparent,
962            Color.Black so they are not class variables.
963    
964            * Thuban/Model/layer.py: Fixes RTbug #1971, 1973.
965            (Layer.Destroy): We don't need to call SetClassification
966            anymore to clear out the back reference in the classifcation
967            to the layer. It's better to set it to None using _set_layer,
968            and we won't be creating another clas object too.
969            (Layer.SetClassification): Classification._set_layer is not
970            recursive so remove all the locking variables. Also clean
971            up the code so that it remains unchanged if something fails.
972    
973            * Thuban/Model/load.py: Fixes RTbug #1971.
974            (SessionLoader.start_classification): Call
975            Classification.SetFieldInfo().
976    
977            * Thuban/Model/save.py: Removed import of Color which wasn't
978            being used.
979    
980            * Thuban/UI/classgen.py: Fixes RTbug #1972.
981            (ClassGenDialog.__init__): Color ramps are now instances
982            already so we don't need to create any new objects.
983            (ClassGenDialog.OnOK): Check for numGroups is no longer
984            necessary because we never use it.
985    
986            * Thuban/UI/classifier.py: Fixes RTbug #1971.
987            (Classifier.__BuildClassification, Classifier.__SetGridTable):
988            Call Classification.SetFieldInfo() instead of SetFieldType.
989    
990            * Thuban/UI/renderer.py: Fixes RTbug #1971.
991    
992            * Thuban/UI/view.py: Fixes RTbug #1974, 1971.
993            (MapCanvas.__init__): Subscribe to the idle time event. Set
994            background color to white.
995            (MapCanvas.OnPaint): Set a flag indicating that we should
996            render the map during idle time. If we already have a bitmap
997            just draw it now.
998            (MapCanvas.OnIdle): New. Render the map only during idle time.
999            This also fixes a problem with the busy cursor under gtk.
1000    
1001            * test/test_classgen.py (ClassGenTest.test_generate_singletons):
1002            Fix calls to generate_singletons because the signature changed.
1003    
1004            * test/test_classification.py: Fix color references and
1005            change calls to Classification.[SetField|SetFieldType] to
1006            SetFieldInfo.
1007    
1008            * test/test_load.py: Fix color references.
1009    
1010            * test/test_load_0_2.py: Fix color references.
1011    
1012            * test/test_save.py (SaveSessionTest.testClassifiedLayer):
1013            Change calls to Classification.[SetField|SetFieldType] to
1014            SetFieldInfo.

1022            New. Test join of two tables with partly equal column names.
1023    
1024            * Thuban/Model/transientdb.py (TransientJoinedTable.create):
1025            If duplicates in left and right tables column names are found,
1026            append '_' (underscores) to the name until it is unique.
1027            Create always new internal names for the resulting table and reference
1028            columns in the join statement with <table>.<column>

1038            sure to use the right internal names even when joining on field
1039            with the same names in both tables. Also, detect duplicate names
1040            in the joined table correctly.
1041

1087    
1088            * Thuban/UI/main.py (wxCHECK_VERSION): Removed. Not needed.

1160            directly to avoid the wxSafeYield() call which generates an
1161            OnPaint event causing infinite recursion. Don't try to catch
1162            exception anymore. This was for before there were limits on map
1163            scaling.

1165    2003-06-23  Bernhard Herzog  <[email protected]>
1166    
1167            Bug fix for RT #1961:
1168    
1169            * Thuban/Model/load.py (SessionLoader.start_derivedshapesource):
1170            Register DerivedShapestores with the session
1171    
1172            * Thuban/Model/session.py (Session.Tables): Make sure each table
1173            is only listed once.
1174    
1175            * test/test_load.py (TestJoinedTable.test): Add check_format call.
1176            Update file contents to match the one written out.
1177    
1178    2003-06-20  Bernhard Herzog  <[email protected]>
1179    
1180            * test/xmlsupport.py (SaxEventLister.startElementNS)
1181            (SaxEventLister.endElementNS): Do not include the qname. Python
1182            2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
1183            is (presumably incorrectly) None, whereas it's a string with the
1184            element name in the later versions.
1185    
1186            * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
1187            (TestEventList.test_even_list_namespace): Update tests to reflect
1188            the new behaviour
1189            (TestEventList.test_even_list_id_normalization): Fix doc-string
1190    
1191    2003-06-20  Jonathan Coles   <[email protected]>
1192    
1193            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
1194            by deriving classes to determine if that layer supports shapes.
1195            (Layer): Override HasShapes and return true.
1196    
1197            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
1198            instead of a direct call to wx[Begin|End]CusyCursor().
1199            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
1200            table data.
1201    
1202            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
1203            New. Wrappers around the wxWindows functions that allow us to
1204            make additional calls such as wxYield which gives the native
1205            system a chance to update the cursor correctly.
1206    
1207            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
1208            instead of a direct call to wx[Begin|End]CusyCursor().
1209    
1210            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
1211            instead of a direct call to wx[Begin|End]CusyCursor().
1212            (MapCanvas.find_shape_at): Check if the current search layer
1213            support shapes, otherwise go on to the next layer.
1214    
1215            * test/test_layer.py: Add tests in each type of layer for
1216            HasClassification() and HasShapes()
1217    
1218    2003-06-20  Jonathan Coles   <[email protected]>
1219    
1220            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
1221            turning on the busy cursor to allow the system to change the
1222            cursor before we begin painting. This fixes a problem that
1223            was occuring only under GTK. Fixes RTbug #1840.
1224    
1225    2003-06-20  Bernhard Herzog  <[email protected]>
1226    
1227            * Resources/XML/thuban-0.8.dtd: New DTD for the new file format

1229    
1230            * Thuban/Model/save.py (sort_data_stores): New. Make topological
1231            sort of the data sources so they can be written with sources that

1233            sources they depend on.
1234            (SessionSaver.__init__): Add idmap instance variable to map from

1242            containers.
1243            (SessionSaver.write_layer): Layer elements now refer to a

1258            addition to filename.
1259            (SessionLoader.start_table, SessionLoader.end_table): Removed.
1260            They were never used in the old formats and aren't needed for the
1261            new.
1262    
1263            * Thuban/Model/session.py (Session.DataContainers): New method to
1264            return all "data containers", i.e. shapestores and tables
1265    
1266            * test/xmlsupport.py (SaxEventLister.__init__)
1267            (SaxEventLister.startElementNS, sax_eventlist): Add support to
1268            normalize IDs.
1269    
1270            * test/test_xmlsupport.py

1292            (SaveSessionTest.testRasterLayer)
1293            (SaveSessionTest.testClassifiedLayer): Adapt to new file format.
1294            (SaveSessionTest.testLayerProjection): The filename used was the

1298            new data sources structures.
1299            (TestStoreSort, MockDataStore): Classes to test the sorting of the
1300            data stores for writing.
1301    
1302            * test/runtests.py: Add CVS keywords
1303    
1304    2003-06-20  Jonathan Coles   <[email protected]>
1305    
1306            * test/test_session.py
1307            (UnreferencedTablesTests.test_unreferenced_tables_with_joins):
1308            Use the cultural_landmark-point.dbf file for the store so that
1309            the table rows and shape count match.
1310    
1311    2003-06-20  Jonathan Coles   <[email protected]>
1312    
1313            * Thuban/Model/data.py (DerivedShapeStore.__init__): Raise
1314            an exception if the number of shapes is different from the
1315            number of rows in the table. Address RTbug #1933.
1316    
1317            * test/test_layer.py (TestLayer.test_derived_store): Add
1318            a test for the new exception in DerivedShapeStore.__init__.
1319    
1320            * test/support.py (FloatTestCase): Removed since there is
1321            already FloatComparisonMixin. Fixes RTbug #1954.
1322            (FloatComparisonMixin.assertFloatEqual): Include test for
1323            infinity that was part of FloatTestCase.
1324    
1325            * test/test_range.py (RangeTest): Inherit from
1326            support.FloatComparisonMixin now that we don't have
1327            support.FloatTestCase.
1328    
1329    2003-06-20  Bernhard Herzog  <[email protected]>
1330    
1331            * test/test_save.py (SaxEventLister, sax_eventlist): Removed. Use
1332            the implementation in xmlsupport instead.
1333            (SaveSessionTest.compare_xml): sax_eventlist is now in xmlsupport
1334    
1335            * test/test_proj.py: Import sax_eventlist from xmlsupport instead
1336            of test_save
1337    
1338    2003-06-20  Bernhard Herzog  <[email protected]>
1339    
1340            * test/test_load.py (LoadSessionTest.check_format): New helper
1341            method to make sure the test files we load might have been written
1342            by the current thuban version.
1343            (ClassificationTest.TestLayers, TestSingleLayer.test)
1344            (TestLayerVisibility.test, TestClassification.test)
1345            (TestLabels.test, TestLayerProjection.test, TestRasterLayer.test):
1346            Add check_format() calls and fix the thuban data to match the data
1347            that would be written by saving the session loaded from it.
1348    
1349            * test/xmlsupport.py (SaxEventLister, sax_eventlist): Copies of
1350            the same class and function in test_save.
1351    
1352            * test/test_xmlsupport.py (TestEventList): New. test cases for
1353            sax_eventlist
1354    
1355    2003-06-20  Bernhard Herzog  <[email protected]>
1356    
1357            * Resources/XML/thuban.dtd: Add comment about which versions of
1358            Thuban are covered by this DTD
1359            (map): Fix content model for layers and raster layers. There can
1360            be any number or layers and raster layers in any order.
1361    
1362    2003-06-20  Jonathan Coles   <[email protected]>
1363    
1364            This is mainly about fixing RTbug #1949.
1365    
1366            * Thuban/Model/classification.py: Remove "from __future__"
1367            import statement since python 2.2 is the earliest supported
1368            version.
1369    
1370            * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
1371            Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES
1372            depending on the units this projection *forwards* into.
1373    
1374            * Thuban/Model/save.py (SessionSaver.write_classification):
1375            Remove unnecessary use of lambdas and nested functions.
1376    
1377            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Do scale
1378            adjustment here if the map projection uses degrees.
1379    
1380            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
1381            scale adjust code since it is now done before calling
1382            this method. Don't do anything if the map projection
1383            is None.
1384    
1385    2003-06-19  Bernhard Herzog  <[email protected]>
1386    
1387            Move version specific load tests to their own file.
1388    
1389            * test/test_load.py: Expand the doc-string to explain a bit how to
1390            handle file format changes.
1391            (TestClassification.test): Update the docstring as this test is
1392            not about Thuban 0.2 anymore.
1393    
1394            * test/test_load_0_2.py: New file with the load tests for thuban
1395            files created with Thuban 0.2 and earlier.
1396    
1397    2003-06-19  Bernhard Herzog  <[email protected]>
1398    
1399            Add XML validation to some of the tests. Validation will only be
1400            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
1401            To make the DTD available to the test cases it's moved into
1402            Resources/XML
1403    
1404            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
1405            for versions up to and including 0.2. Two slight changes: added an
1406            encoding specification and fixed the comment which refered to
1407            GRASS, not Thuban
1408    
1409            * test/xmlsupport.py: New support module for tests involving XML.
1410            Currently there's a mix-in class for XML validation.
1411    
1412            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
1413    
1414            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
1415            so that we can validate the
1416            (SaveSessionTest.testEmptySession)
1417            (SaveSessionTest.testSingleLayer)
1418            (SaveSessionTest.testSingleLayer)
1419            (SaveSessionTest.testLayerProjection)
1420            (SaveSessionTest.testRasterLayer)
1421            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
1422    
1423            * test/runtests.py (main): Call print_additional_summary instead
1424            of print_garbage_information
1425    
1426            * test/support.py (resource_dir): New function to return the
1427            "Resource" subdirectory
1428            (print_additional_summary): New function to combine several
1429            summary functions
1430            (run_tests): Use print_additional_summary instead of calling
1431            print_garbage_information directly
1432    
1433    2003-06-19  Bernhard Herzog  <[email protected]>
1434    
1435            * Doc/thuban.dtd (classification): Correct the content model of
1436            the classification element.
1437            (projection): Add the "name" attribute
1438    
1439    2003-06-19  Frank Koormann   <[email protected]>
1440    
1441            MERGE from the greater-ms3 branch.
1442    
1443            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
1444            scale if projection is latlong to get better estimate.
1445    
1446            Fix problem of hidden properties dialog under windows after double
1447            click on layer tree:
1448            The tree control always gets an Expanded / Collapsed event after
1449            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
1450            raises the already displayed window.
1451    
1452            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
1453            raiseProperties initialized to prevent endless loops
1454            (LegendTree._OnItemActivated): Depending on self.raiseProperties
1455            simply raise the properties or open the dialog and issue a second
1456            event.
1457    
1458    2003-06-18  Jonathan Coles   <[email protected]>
1459    
1460            * setup.py: Fix a few problems that occured under Windows.
1461    
1462    2003-06-18  Jonathan Coles   <[email protected]>
1463    
1464            When Thuban loaded the map was redrawn twice because the
1465            legend was being opened after the mainwindow was created
1466            and not during its creation. This meant the map was drawn
1467            initially and then had to be redrawn when the legend
1468            caused the display to change. Now the legend is opened
1469            in the mainwindow constructor which resolves this issue.
1470    
1471            Also, although we were checking for the existence of
1472            gdal and gdalwarp modules, the gdalwarp extension was
1473            still being compiled (which may fail if the system doesn't
1474            have gdal installed). the build_ext command to setup.py
1475            now accepts the flags --with-gdal and --without-gdal.
1476            If --without-gdal is specified setup.py will try to
1477            use the gdal parameters specified by gdal-config. Under
1478            windows, those parameters have to be set in setup.py
1479            as with proj4 an wxWindows.
1480    
1481            * setup.py: Use a list instead of seperate variables for
1482            extension parameters so we can create a generic function
1483            that runs an appropriate *-config script.
1484            (run_cs_script): Renamed from run_wx_script and modified
1485            to accept a second argument which is a list of lists to
1486            be filled in by the values returned from running the command.
1487            (thuban_build_ext): New. Extends the build_ext command and
1488            provides the options --with-gdal/--without-gdal which then
1489            optionally includes the gdalwarp extension.
1490    
1491            * Thuban/Model/resource.py: First check if we can import
1492            the gdalwarp Thuban extension before checking for gdal.
1493            Also added some comments.
1494            
1495            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
1496            the map is None which may be the case if none has been loaded
1497            yet.
1498    
1499            * Thuban/UI/main.py (main): Remove call to ShowLegend.
1500    
1501            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
1502    
1503            * Thuban/UI/renderer.py: Check for gdal support before importing
1504            gdalwarp.
1505            (MapRenderer.render_map): Only try to optimize if we have gdal
1506            support otherwise nothing will get drawn.
1507    
1508            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
1509            during startup before a map has been created. Check if map is None
1510            before using it and do nothing if it is.
1511    
1512    2003-06-17  Jonathan Coles   <[email protected]>
1513    
1514            Fix the problem with raster layers under Windows that caused
1515            Thuban to crash. The view should respond to layer projection
1516            changed events to update the display. Changes to a projection
1517            should not cause the map to be set to full extent.
1518            
1519            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
1520            current_map_proj to remember the current map projection so that
1521            when the projection changes we know what the previous projection
1522            was.
1523            (MapCanvas.SetMap): Unsubscribe and subscribe to
1524            LAYER_PROJECTION_CHANGED events.
1525            (MapCanvas.projection_changed): Split into two methods that respond
1526            to map and layer projection changes.
1527            (MapCanvas.map_projection_changed): New. Takes the current view and
1528            projects it using the new projection. This does not cause the
1529            map to be redrawn at full extent.
1530            (MapCanvas.layer_projection_changed): New. Cause a redraw which
1531            will draw each layer in its new projection.
1532            
1533            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
1534            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
1535            under Windows.
1536            
1537            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
1538            to twice sizeof(void*) because there are two digits for each
1539            hex byte.
1540    
1541    2003-06-16  Bernhard Herzog  <[email protected]>
1542    
1543            Update to the layer interface: Direct access to the table,
1544            shapetable, shapefile and filename attributes is now actively
1545            deprecated by issuing deprecation warnings for all places where
1546            this happens.
1547    
1548            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
1549            to the instance variables table, shapetable, shapefile and
1550            filename via __getattr__ so that we can issue a deprecation
1551            warning.
1552            (Layer.SetShapeStore): Don't set the deprecated instance variables
1553            any more
1554            (Layer.SetShapeStore): Don't use deprecated layer instance
1555            variables
1556            (Layer.Destroy): No need to explicitly remove the instance
1557            variables any more
1558            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
1559            instance variables
1560    
1561            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
1562            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
1563            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
1564            use deprecated layer instance variables
1565    
1566            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
1567            deprecated layer instance variables
1568    
1569            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
1570            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
1571            instance variables
1572    
1573            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
1574            deprecated layer instance variables
1575

1578    
1579            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
1580            deprecated layer instance variables
1581    
1582            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
1583            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
1584            variables
1585    
1586            * test/runtests.py (main): Turn Thuban's deprecation warnings into
1587            errors so that they're cought by the tests
1588    
1589            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
1590            layer instance variables
1591    
1592    2003-06-16  Jonathan Coles   <[email protected]>
1593    
1594            Fix a problem under Windows whereby if the user double-clicks on a
1595            layer in the legend that tree item will expand or collapse as well
1596            as open the layer properties dialog. The state of the tree item
1597            should not be affected.
1598    
1599            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
1600            preventExpandCollapse and subscribe to expanding and collapsing
1601            events.
1602            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
1603            collapsing events and will veto the event if it has been triggered
1604            by the user double clicking on a layer.
1605            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
1606            that an expanding/collapsing event should be vetoed.
1607    
1608    2003-06-13  Bernhard Herzog  <[email protected]>
1609    
1610            * Thuban/UI/classifier.py (Classifier.OnClose)
1611            (Classifier.map_layers_removed)
1612            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
1613            in OnClose and not in map_layers_removed or
1614            layer_shapestore_replaced to make sure it always happens when the
1615            dialog is closed
1616    
1617    2003-06-13  Jonathan Coles   <[email protected]>
1618    
1619            This puts back a fix for Windows where a panel is needed so that
1620            the background of the table view appears correctly.
1621    
1622            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
1623            object that can be used by derived classes to place any
1624            controls (including the grid) onto.
1625            (QueryTableFrame.__init__): Use the panel as the parent window
1626            for all the controls. Reparent the grid so that the panel is
1627            the parent. Call UpdateStatusText() to correctly initialize
1628            the status bar.
1629    
1630    2003-06-13  Jonathan Coles   <[email protected]>
1631    
1632            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
1633            from wxFrame (as opposed to wxDialog like the other classes)
1634            but otherwise behaves like the other classes. This is needed
1635            for the TableView which isn't really a dialog and needs to
1636            have a status bar and control buttons.
1637    
1638            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
1639            instance variable to keep track of how many rows are selected.
1640            Subscribe once to the the events we are interested in.
1641            (ThubanGrid.OnRangeSelect): Only handle event if event handling
1642            hasn't been turned off.
1643            (ThubanGrid.OnSelectCell): Only handle event if event handling
1644            hasn't been turned off.
1645            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
1646            as an event listener (which changes the event handler stack)
1647            simply set an instance variable to False. This is checked in
1648            the event handlers.
1649            (ThubanGrid.GetNumberSelected): Return the number of currently
1650            selected rows.
1651            (TableFrame): Inherit from ThubanFrame so we can have a
1652            status bar and control buttons.
1653            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
1654            Explicitly set which items are selected in the operator choice and
1655            action choice so there is always a valid selection. Fixes RTbug #1941.
1656            Subscribe to grid cell selection events so we can update the
1657            status bar.
1658            (QueryTableFrame.UpdateStatusText): Update the status bar with
1659            how many rows are in the grid, how many columns, and how many
1660            rows are selected.
1661            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
1662            Call UpdateStatusText when cells are (de)selected.
1663            (QueryTableFrame.OnQuery): Use the string value in the value
1664            combo if either the selected item index is 0 or if the string
1665            cannot be found in the predefined list (this happens if the
1666            user changes the text). Fixes RTbug #1940.
1667            Only turn off the grid event listeners if there a query comes
1668            back with a none empty list of ids. in the case that the list
1669            is empty this causes a grid.ClearSelection() call to actually
1670            clear the grid selection which causes the selected items in
1671            the map to be deselected. Fixes RTbug #1939.
1672    
1673            * test/test_save.py (XMLWriterTest.Encode): Check return values.
1674            Fixes RTbug #1851.
1675    
1676    2003-06-13  Bernhard Herzog  <[email protected]>
1677    
1678            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
1679            self.selected_shape with the current selection to make sure the
1680            contents of the dialog are up to date when it's shown for the
1681            first time.
1682            The dialog used to work without this by luck. The recent fix to
1683            the connector module 'broke' a 'feature' the identify view was
1684            relying on, i.e that subscribing to a message in response to
1685            receiving a message of that type would mean that the new
1686            subscriber would also be called for the same message.
1687            
1688    2003-06-12  Jonathan Coles   <[email protected]>
1689    
1690            * extensions/thuban/gdalwarp.cpp: Removed debug printing as
1691            the image is rendered. Fixes RTbug #1937.
1692    
1693    2003-06-12  Jonathan Coles   <[email protected]>
1694    
1695            * Thuban/Lib/fileutil.py: As is done under Windows, create the
1696            user directory if it doesn't exist on a posix system.
1697            Fixes RTbug #1815.
1698    
1699            * Thuban/Model/resource.py (get_user_proj_files): Moved the
1700            called to get_application_dir here, so that the directory
1701            will only be called if this method is invoked.
1702    
1703            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
1704            the projfilepath if no projection is selected.
1705    
1706    2003-06-12  Jonathan Coles   <[email protected]>
1707    
1708            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
1709            the scalebar if the current map has no projection set.
1710    
1711            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
1712            projfilepath label to just the basename of the projection file
1713            rather than include the entire path.
1714    
1715            * Thuban/Model/resource.py: Fix missed proj functions that
1716            needed to be renamed.
1717    
1718    2003-06-12  Jonathan Coles   <[email protected]>
1719    
1720            * Thuban/Model/classification.py: Removed assert statements that
1721            tested if the variable was an instance of Color.
1722    
1723            * Thuban/Model/color.py (Color): Remove commented code that isn't
1724            used.
1725            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
1726            Fixes RTbug #1835.
1727            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
1728            Needed now that the class doesn't inherit from Color.
1729    
1730    2003-06-12  Jonathan Coles   <[email protected]>
1731    
1732            * test/test_save.py (XMLWriterTest.testEncode): Explicitly
1733            check unicode strings.
1734    
1735            * test/test_layer.py: Check for existence of gdal.
1736

1743            that was in save.py
1744    
1745    2003-06-12  Jonathan Coles   <[email protected]>
1746    
1747            This is largely a collection of bug fixes. We also handle the
1748            case where gdal is not on the system. The XMLReader and XMLWriter
1749            classes were moved into there own files to resolve some circular
1750            import references and because they shouldn't really be in the
1751            file that is dediciated to reading/writing session files since
1752            they are also used elsewhere.
1753    
1754            * Thuban/Model/classgen.py: Renamed functions to follow the
1755            function_names_with_underscores style. Fixes RTbug #1903.

1811    
1812            * test/test_classgen.py: Add tests for generate_singletons,
1813            generate_uniform_distribution, generate_quantiles. Fixes RTbug #1903.
1814            (test_calculate_quantiles): Fix some tests to catch the new
1815            ValueError that is raised.
1816

1916    2003-06-05  Frank Koormann  <[email protected]>
1917    
1918            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
1919            once on initialisation (Former implementation resulted in multiple
1920            entries for each projection).
1921            (ProjFrame.__FillAvailList): selectProj as second optional parameter,
1922            if set, select the projection found under the specified name. This

1925            (ProjFrame._OnSave, ProjFrame._OnAddToList):
1926            Updated call of ProjFrame.__FillAvailList

1944    
1945            Do not cache the values returned by the tree widget's
1946            GetFirstChild and GetNextChild methods because it led to lots of
1947            segfaults. The new way requires more brute force but is more
1948            reliable.
1949    
1950            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
1951            variable layer2id

1986            instead of Publisher to reflect reality better and to accomodate
1987            the fact that SetTitle now calls changed instead of issue
1988    
1989    2003-06-02  Bernhard Herzog  <[email protected]>
1990    
1991            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource

2002            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
2003            variables to None that have direct or indirect references to

2041            * Thuban/UI/classgen.py: Use classgen functions that were part
2042            of the ClassGenerator class. Put try/finally blocks around

2080            to be compiled as a standalone app. Now the code can only be
2081            called from Python which simplifies the parameter passing.
2082            (ProjectRasterFile): Handle Python arguments. Remove code that
2083            checks for a destination dataset. Add more clean up code.
2084

2368            or table_to_csv depending on file selection.
2369    
2370            * test/test_dbf_table.py:
2371            Test table_to_dbf (extension of former part of test).
2372

2417            implementation that still needs work.
2418    
2419            * Thuban/Model/layer.py (Layer.TreeInfo): Added filename.
2420    
2421    2003-05-22  Frank Koormann  <[email protected]>
2422    
2423            * Thuban/Model/transientdb.py (TransientJoinedTable.__init__):
2424            Added "outer_join = False" as optional parameter.
2425            (TransientJoinedTable.create): If outer join is true, perform a

2428    
2429            * Thuban/UI/join.py (JoinDialog.__init__): Checkbox for outer join.
2430            (JoinDialog.OnJoin): Consider outer join check box.

2611            (ProjFrame.__DoOnProjAvail): Determine position of current projection
2612            using the wxListBox.FindString() method. Still a problem (#1886)

2656    
2657            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
2658            into try block. AddLayer doesn't throw any exceptions anymore.
2659            (MainWindow.AddRasterLayer): Move constructor of RasterLayer into
2660            try block.
2661    
2662            * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as
2663            the first item in choices. Fixes RTBug #1882.
2664    
2665            * Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale
2666            has gone to 0 which is a serious problem. abort.
2667            (MapRenderer.draw_raster_layer): Catch IOError seperately and
2668            print the error from GDAL.
2669    
2670            * Thuban/UI/tableview.py (TableGrid.__init__): Call
2671            ToggleEventListeners to turn on listening.
2672            (TableGrid.ToggleEventListeners): New. Turns event listening on
2673            and off so as to prevent excessive messages.
2674            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
2675            to suppress excessive messages when selecting many rows.
2676            Fixes RTBug #1880.
2677    
2678            * Thuban/UI/view.py: Added checks against if scale == 0. This
2679            is a serious problem that can occur when an image without
2680            geo data is loading and causes the map projection bounds to
2681            go to infinity. Right now, the solution is to simply try
2682            to recover.
2683    
2684            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
2685            to set the MFILEReceiver attributes even if the data is NULL.
2686    
2687            * extensions/thuban/gdalwarp.cpp: Improved the error handling
2688            and passed GDAL messages back up to the Python layer. Also
2689            tried to fix some memory leaks that were present in the original
2690            utility but didn't matter because the program aborted.
2691    
2692            * test/test_range.py: Copied over tests from SciParam. Removed
2693            tests against importing. Fixes RTBug #1867.
2694    
2695    2003-05-21  Bernhard Herzog  <[email protected]>
2696    
2697            * test/test_load.py: Remove unused imports and restructure the
2698            test code
2699            (LoadSessionTest): Split into one class for each test and turn
2700            LoadSessionTest itself into the base class for all such session
2701            tests.
2702            (ClassificationTest): New base class for load tests that test
2703            classifications
2704            (TestSingleLayer, TestLayerVisibility, TestClassification)
2705            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
2706            for the individual tests
2707    
2708            * test/support.py (FileLoadTestCase.filename): New base class for
2709            file loading tests
2710    
2711    2003-05-21  Jan-Oliver Wagner <[email protected]>
2712    
2713            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
2714            Mercator' to 'UTM Zone 32' as a more convenient example.
2715            Added 'Gauss Krueger Zone 6'.
2716    
2717            * Data/iceland_sample_raster.thuban: political polygon now
2718            filled transparent to have the raster image visible at once.
2719    
2720    2003-05-21  Frank Koormann  <[email protected]>
2721    
2722            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
2723            OnClose() to keep in sync with extensions. Internally Thuban
2724            still uses "underscored" names.
2725    
2726    2003-05-20  Jonathan Coles   <[email protected]>
2727    
2728            This puts back Raster layer support. These layers support projections
2729            through the GDAL library. Currently, the CVS version is being used.
2730            There are no Debian packages available although this may change soon.
2731            A GDAL driver was extended to support writing to memory rather to
2732            files.
2733    
2734            There is still some work that needs to be done, such as some error
2735            handling when loading invalid images or when there is a problem
2736            projecting the image. This putback simply checks in the majority
2737            of the work.
2738    
2739            * setup.py: Add gdalwarp library extension.
2740    
2741            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
2742            Defaults to False, but can be overridden by subclasses if they
2743            support classification.
2744            (RasterLayer): New. Defines a new layer that represents an
2745            image.
2746    
2747            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
2748            tag handler.
2749            (SessionLoader.start_layer): Encode the filename.
2750            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
2751            New. Supports reading a rasterlayer tag.
2752    
2753            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
2754    
2755            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
2756            get a string in Latin1. If we get such as string convert it to
2757            unicode first, otherwise leave if alone before encoding.
2758            (SessionSaver.write_layer): Add support for writing both Layers
2759            and RasterLayers.
2760    
2761            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
2762            The right argument may not be a string, it could also be a Column.
2763    
2764            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
2765            Make initial window size 600x400. Fixes RTBug #1872.
2766    
2767            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
2768            the dialog is constructed so that we can support layers that
2769            do not have classifications.
2770            (Classifier._OnTry): Only build a classification if the layer
2771            supports one.
2772    
2773            * Thuban/UI/legend.py: Change all checks that a layer is an
2774            instance of Layer into checks against BaseLayer.
2775            (LegendTree.__FillTreeLayer): Only add children to a branch if
2776            the layer supports classification.
2777    
2778            * Thuban/UI/mainwindow.py (MainWindow.NewSession,
2779            MainWindow.OpenSession): Don't proceed with an action if the
2780            user chooses Cancel when they are asked to save changes.
2781            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
2782            user to select an image file. Create a new RasterLayer and add
2783            it to the map.
2784    
2785            * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
2786            for rendering RasterLayer layers.
2787            (MapRenderer.draw_raster_layer): Actually method that calls
2788            the GDALWarp python wrapper and constructs an image from the
2789            data returned.
2790    
2791            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the
2792            Choices symbols to match those used in the table query method.
2793            Replace deprecated method calls on table with new method names.
2794    
2795            * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
2796            how small the scale can get. This still needs more testing.
2797    
2798            * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
2799            Provides a driver to output in .bmp format.
2800    
2801            * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h:
2802            New. Provides IO routines which write to memory, rather than a file.
2803    
2804            * extensions/thuban/gdalwarp.cpp: New, but basically a direct copy
2805            of the gdalwarp utility provided in GDAL. Added function calls
2806            that can be accessed from python.
2807    
2808            * Data/iceland_sample_raster.thuban: New. Sample file that uses
2809            a raster layer.

2820            (TestTransientTable.test_auto_transient_table_query): Added a test
2821            for using a Column object as the "right" parameter to a query.
2822    
2823    2003-05-19  Frank Koormann  <[email protected]>
2824    
2825            * Thuban/version.py (get_changelog_date):

2841    
2842            * Thuban/Model/save.py: Remove some unused imports including the
2843            __future__ import for nested_scopes as Thuban relies on Python 2.2
2844            now.
2845            (XMLWriter.encode): Remove the special case for a None argument.
2846            In the saver encode is always called with a string argument.
2847    
2848    2003-05-16  Bernhard Herzog  <[email protected]>
2849    
2850            * Thuban/UI/__init__.py: Remove the work-around for the locale bug
2851            in wxPython (at least when usinvg wxGTK) prior to 2.4. The symptom
2852            of the bug was that e.g. float("1.2") would fail. Thuban now
2853            requires 2.4.x.
2854            
2855    2003-05-16  Frank Koormann   <[email protected]>
2856    
2857            Printing enhancement and WMF export (under Win32)

2896    
2897    2003-05-14  Jonathan Coles   <[email protected]>

2904            bounds of the generated classes.
2905    
2906            * Thuban/Model/range.py (Range.number_re): Now accepts floats that
2907            do not have a leading 0 (.5 is now accepted as well as 0.5).
2908

2920    
2921            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Replace call
2922            to table.UniqueValues() with calls that retrieve all the values
2923            from the table. This will need to be replaced by a method on table
2924            which can simply return the list (perhaps more efficiently).
2925    
2926    2003-05-12  Jonathan Coles   <[email protected]>
2927    
2928            The return value of ClassGenerator.CalculateQuantiles has changed.
2929            Refer to the documentation for details.

2932            new return values.
2933    
2934            * Thuban/Model/classgen.py
2935            (ClassGenerator.GenQuantiles): Add comments describing the parameters,

2942    
2943    2003-05-12  Frank Koormann <[email protected]>
2944

2967            (ClassGroupRange): Use the Range class to store the underlying
2968            range information. The interface remains the same, except for
2969            GetRange(), and you can also supply a Range object as the min
2970            parameter to SetRange or __init__.
2971

2973            string appropriately for use in Thuban. Fixes RTbug #1851.
2974            (SessionLoader.end_projection): Handle the context of the
2975            projection tag a bit better by looking at what objects are not
2976            None. There was an assumption that a projection tag for a map
2977            could occur before any layers.
2978            (SessionLoader.start_clrange): Provide backward compatibility for
2979            reading min/max values as well as the new range parameter.
2980    
2981            * Thuban/Model/map.py: Explicit imports.
2982

3008            (MainWindow.choose_color): Removed. No longer needed.
3009    
3010            * Thuban/UI/projdialog.py (ProjFrame.__VerifyButtons): Save button
3011            should be disabled if no projection is selected in the available
3012            list.

3014            * Thuban/UI/renderer.py: Explicit imports.
3015    
3016            * Thuban/UI/tableview.py (TableGrid.OnRangeSelect): Fix some issues
3017            with correctly selecting the rows and issuing the right events.
3018            Be sure to call Skip() to allow the grid to do some of its own
3019            handling which allows the rows to actually be selected.
3020            (LayerTableGrid.select_shapes): Rename from select_shape. Supports
3021            selecting multiple shapes.
3022            (LayerTableFrame): Support for building Queries.

3038            the classifer table and elsewhere.
3039    
3040            * Thuban/UI/join.py: New. Initial Join dialog. No real functionality

3063    
3064            * Thuban/Model/scalebar.py: Rendering moved to Thuban/UI/scalebar.py
3065            (deriveInterval):
3066            Calculate scalebar interval and unit which fits in width for scale.
3067            (roundInterval): Round float.

3132            Resources/Bitmaps/fullselextent.xpm: Replaced the place holders with
3133            new icons.
3134    
3135    2003-05-06  Bernhard Herzog  <[email protected]>
3136

3159    
3160    2003-05-06  Bernhard Herzog  <[email protected]>
3161    
3162            Convert all table users to use the new table interface. This only
3163            covers Thuban itself, not GREAT-ER or other applications built on
3164            Thuban yet, so the compatibility interface stays in place for the
3165            time being but it now issues DeprecationWarnings.
3166    
3167            Finally, the new Table interface has a new method, HasColumn.
3168    
3169            * Thuban/Model/table.py (OldTableInterfaceMixin): All methods
3170            issue deprecation warnings when they're. The warnings refer to the

3174    
3175            * test/test_table.py: Ignore the deprecation warnings for the old
3176            table in the tests in this module. The purpose of the tests is to
3177            test the old interface, after all.

3179            * test/test_transientdb.py
3180            (TestTransientTable.run_iceland_political_tests): Use the
3181            constants for the types. Add a test for HasColumn

3201            to new table interface
3202    
3203            * Thuban/Model/transientdb.py (TransientTableBase.HasColumn)
3204            (AutoTransientTable.HasColumn): Implement the new table interface
3205            method
3206            (AutoTransientTable.ReadRowAsDict, AutoTransientTable.ValueRange)
3207            (AutoTransientTable.UniqueValues): Adapt to new table interface
3208    
3209            * Thuban/Model/layer.py (Layer.SetShapeStore, Layer.GetFieldType):

3227            Addresses the "Selection Extent" wish of RTbug #1787.
3228    
3229            * Resources/Bitmaps/fulllayerextent.xpm,
3230            Resources/Bitmaps/fullselextent.xpm: Bitmaps for layer and selection
3231            extent. These are just place holders for the real bitmaps.
3232    
3233            * Thuban/Model/layer.py (Shape): Since a Shape is immutable only
3234            calculate the bounding box once (the first time compute_bbox() is
3235            called).
3236            (Layer.ShapesBoundingBox): New. Given a list of shape ids, return
3237            the bounding box for the shapes in lat/long coordinates.
3238    
3239            * Thuban/UI/mainwindow.py: Added new "Full selection extent" menu
3240            option.

3249            true if there are any selected shapes.
3250    
3251            * Thuban/UI/view.py (MapCanvas): Added delegated method
3252            HasSelectedShapes.
3253            (MapCanvas.FitSelectedToWindow): New. Centers and scales any selected
3254            shapes on the canvas using the map projection (if any).
3255    
3256            * test/test_layer.py (TestLayer.test_arc_layer): Add some tests
3257            for Layer.ShapesBoundingBox().
3258    
3259    2003-05-06  Bernhard Herzog  <[email protected]>
3260    
3261            * Resources/Projections/defaults.proj: Fix spelling of Mercator
3262    
3263    2003-05-05  Jonathan Coles   <[email protected]>

3265            Addresses the "Full Layer Extent" wish of RTbug #1787.
3266    
3267            * Resources/Projections/defaults.proj: Added UK National Grid.
3268    
3269            * Thuban/UI/mainwindow.py: Added new "Full layer extent" menu option.

3276    2003-05-05  Bernhard Herzog  <[email protected]>
3277    
3278            Convert the table implementations to a new table interface. All
3279            tables use a common mixin class to provide backwards compatibility
3280            until all table users have been updated.
3281    
3282            * Thuban/Model/table.py (OldTableInterfaceMixin): Mixin class to
3283            provide backwards compatibility for table classes implementing the
3284            new interface
3285            (DBFTable, MemoryTable): Implement the new table interface. Use
3286            OldTableInterfaceMixin as base for compatibility
3287            (DBFColumn, MemoryColumn): New. Column description for DBFTable
3288            and MemoryTable resp.
3289    
3290            * test/test_dbf_table.py: New. Test cases for the DBFTable with
3291            the new table interface.
3292    
3293            * test/test_memory_table.py: New. Test cases for the MemoryTable
3294            with the new table interface.
3295    
3296            * test/test_table.py: Document the all tests in this file as only
3297            for backwards compatibility. The equivalent tests for the new
3298            interface are in test_memory_table.py and test_dbf_table.py
3299            (MemoryTableTest.test_read): field_info should be returning tuples
3300            with four items
3301            (MemoryTableTest.test_write): Make doc-string a more precise.
3302    
3303            * Thuban/Model/transientdb.py (TransientTableBase): Convert to new
3304            table interface. Derive from from OldTableInterfaceMixin for
3305            compatibility.
3306            (TransientTableBase.create): New intance variable column_map to
3307            map from names and indices to column objects
3308            (TransientTable.create): Use the new table interface of the input
3309            table
3310            (AutoTransientTable): Convert to new table interface. Derive from
3311            from OldTableInterfaceMixin for compatibility.
3312            (AutoTransientTable.write_record): Removed. It's not implemented
3313            yet and we still have to decide how to handle writing with the new
3314            table and data framework.
3315    
3316            * test/test_transientdb.py
3317            (TestTransientTable.run_iceland_political_tests)
3318            (TestTransientTable.test_transient_joined_table): Use the new
3319            table interface
3320    
3321    2003-05-05  Jonathan Coles   <[email protected]>
3322    
3323            This is namely a collection of UI updates to improve user interactivity.
3324            Tabbing between controls now exists and you can use ESC to close dialog
3325            boxes; ENTER will active the default button.
3326    
3327            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Rearrange the
3328            order that the controls are created so that tabbing works correctly.
3329            (ClassGenDialog.OnOK): Renamed from _OnGenerate() so that the
3330            wxDialog can handle the default button correctly.
3331            (ClassGenDialog.OnCancel): Renamed from _OnCloseBtn() for the
3332            same reasons as for OnOK.
3333            (GenUniformPanel._OnRetrieve): Call wxBeginBusyCursor/wxEndBusyCursor
3334            when we ask the table for the maximum/minimum values of a field
3335            which could take a very long time.
3336    
3337            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange the
3338            order that the controls are created so that tabbing works correctly.
3339            (SelectPropertiesDialog.__init__): Rearrange the order that the
3340            controls are created so that tabbing works correctly.
3341    
3342            * Thuban/UI/dialogs.py: Copied NonModalDialog box and changed it
3343            to derive from a wxDialog but behave like the original implementation
3344            which was derived from a wxFrame. wxDialog provides useful key
3345            handling functionality like ESC calling OnCancel and ENTER calling
3346            OnOK which is lost with wxFrame.
3347    
3348            * Thuban/UI/mainwindow.py: Add "..." to menu items that will open
3349            new dialogs.
3350    
3351            * Thuban/UI/projdialog.py (ProjFrame.__init__): Rearrange the
3352            order that the controls are created so that tabbing works correctly.
3353            (ProjFrame.OnApply): Renamed from _OnTry() to use wxDialog behaviour.
3354            (ProjFrame.OnOK): Renamed from _OnOK() to use wxDialog behaviour.
3355            (ProjFrame.OnCancel): Renamed from _OnClose() to use wxDialog behaviour.
3356            (ProjPanel.__init__): Add "Airy" to the list of ellipsoids so we
3357            can provide the "UK National Grid" as a default projection.
3358            (UTMPanel.__init__): Rearrange the order that the controls are
3359            created so that tabbing works correctly.
3360    
3361    2003-05-05  Bernhard Herzog  <[email protected]>
3362    
3363            * extensions/thuban/wxproj.cpp: Fix some of the comments.
3364            (project_point): If a map projection but no layer projection is
3365            given, convert degrees to radians before applying the map
3366            projection.
3367    
3368            * Thuban/UI/tableview.py (TableGrid.disallow_messages)
3369            (TableGrid.allow_messages): New methods to make it possible to
3370            inhibit message sending.
3371            (TableGrid.issue): Only send the message if not inhibited.
3372            (LayerTableGrid.select_shape): Use the new methods to make sure
3373            that no ROW_SELECTED message is sent while we're updating the
3374            selected rows to match the selected shapes.
3375    
3376    2003-05-02  Jan-Oliver Wagner <[email protected]>
3377    
3378            Implementation of MemoryTable.
3379    
3380            * Thuban/Model/table.py (MemoryTable): New. Quite simple table
3381            implementation that operates on a list of tuples. All of the data
3382            are kept in the memory.
3383    
3384            * test/test_table.py (MemoryTableTest): New.
3385    
3386            * test/test_transientdb.py (SimpleTable): Removed.
3387            (TestTransientTable.test_transient_joined_table,
3388            (TestTransientTable.test_transient_table_read_twice): Replaced
3389            SimpleTable by MemoryTable.
3390    
3391    2003-04-30  Jonathan Coles   <[email protected]>
3392    
3393            * Data/iceland_sample.thuban: Now contains correct projections
3394            for each of the layers.
3395    
3396            * Resources/Projections/defaults.proj: Geographic projection
3397            contains unit conversion parameter.
3398    
3399    2003-04-30  Jonathan Coles   <[email protected]>
3400    
3401            The most important part of this putback is the projection changes.
3402            It should now be possible to specify the projection that a layer
3403            is in and then specify a different projection for the map. The
3404            projection dialog has an extra parameter for a geographic projection
3405            which lets the user select if the input is in degrees or radians.
3406    
3407            * Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring
3408            to say that the parameter is a tuple of unprojected
3409            points (which is what the callers to this method were assuming).
3410            Also, since the points are unprojected we need to projected them.
3411    
3412            * Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp,
3413            LegendTree.MoveCurrentItemDown): If the layer or any of the layer's
3414            groups are selected, move the layer up/down. Fixes RTbug #1833.
3415    
3416            * Thuban/UI/mainwindow.py: Move menu item map_rename up.
3417    
3418            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing
3419            parameter in call to SetClientData.

3421            source data is in (Radians or Degrees).
3422    
3423            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize
3424            the rendering loop by reducing the number of if's, removing the
3425            unnecessary try/except block, and checking if the old group
3426            is the same as the new one (which happens a lot if there is
3427            no classification, or lots of shapes are in the same group).
3428    
3429            * Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block
3430            around the redraw routine to try to catch problems that the user
3431            may create by selecting invalid projections for the data set and
3432            map. Clears the display if there are any problems and prints the
3433            error.
3434            (MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled
3435            rectangle.
3436    
3437            * extensions/thuban/wxproj.cpp (project_point): First invert the
3438            supplied point (which should be in projected coordinates) using
3439            the layer's projection and then project the point using the
3440            map's projection.
3441            (project_points): Use project_point() to project each point.

3444    
3445            * Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug:
3446            don't set the Classification to None if the classfication field
3447            is None (ie only a DEFAULT).

3453            * Thuban/UI/mainwindow.py (MainWindow.identify_view_on_demand): Do
3454            not pop up the dialog if the selection becomes empty (this could
3455            happen if e.g. a new selection is opened while the identify tool
3456            is active and dialog had been closed)
3457

3463            record twice works. The implementation uses the new instance
3464            variable read_record_last_result
3465    
3466            * test/test_transientdb.py
3467            (TestTransientTable.test_transient_table_read_twice): New test
3468            case for the above bug-fix.

3481    
3482            * Thuban/Model/session.py (Session.Destroy): Explicitly close the
3483            transient DB if it exists to make sure it doesn't leave a journal
3484            file in the temp directory.
3485    
3486            * Thuban/Model/transientdb.py (TransientDatabase.close): Set
3487            self.conn to None after closing the connection to make sure it's
