2    
3            Rearrange the renderers a bit, partly in preparation for changes
4            required for the postgis merge, partly to make it more testable.
5            Also make the representation of coordinates in Shapes more
6            consistent.
7    
8            * Thuban/UI/renderer.py (MapRenderer): Most of the code/methods in
9            this class is now in BaseRenderer. This class is now practically
10            only a specialization of BaseRenderer for rendering to an actual
11            wx DC.
12            (ScreenRenderer.draw_shape_layer): Use self.low_level_renderer()
13            to get the shapetype specific rendering functions.
14    
15            * Thuban/UI/baserenderer.py: New file with the basic rendering
16            logic. The code in this file is completely independend of wx.
17            (BaseRenderer): Class with the basic rendering logic
18    
19            * test/test_baserenderer.py: New. Test cases for BaseRenderer
20    
21            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
22            error_on_redraw to guard agains endless loops and stack overflows
23            when there's a bug in the rendering code that raises exceptions.
24            (MapCanvas.OnIdle, MapCanvas._do_redraw): Split the actual
25            rendering into a separate method _do_redraw so that error handling
26            is a bit easier. When an exception occurs, set error_on_redraw to
27            true. When it's true on entry to OnIdle do nothing and return
28            immediately.
29    
30            * Thuban/Model/data.py (ShapefileStore.Shape): For consistency, a
31            Shape object will always have the coordinates as a list of list of
32            coordinate pairs (tuples).
33            (Shape.compute_bbox): Adapt to new representation.
34    
35            * Thuban/UI/viewport.py (ViewPort.find_shape_at)
36            (ViewPort.LabelShapeAt): Adapt to new coordinate representation in
37            Shape objects.
38    
39            * test/test_shapefilestore.py
40            (ShapefileStoreTests.assertFloatTuplesEqual)
41            (ShapefileStoreTests.assertPointListEquals): Rename to
42            assertPointListEquals and change purpose to checking equality of
43            the lists returned by Shape.Points().
44            (TestShapefileStoreArc.test_shape)
45            (TestShapefileStorePolygon.test_shape)
46            (TestShapefileStorePoint.test_shape): Use the new
47            assertPointListEquals instead of assertFloatTuplesEqual
48    
49            * test/test_layer.py (TestLayer.assertFloatTuplesEqual)
50            (TestLayer.assertPointListEquals): Rename to assertPointListEquals
51            and change purpose to checking equality of the lists returned by
52            Shape.Points().
53            (TestLayer.test_arc_layer, TestLayer.test_arc_layer)
54            (TestLayer.test_polygon_layer, TestLayer.test_point_layer)
55            (TestLayer.test_derived_store): Use the new assertPointListEquals
56            instead of assertFloatTuplesEqual
57    
58            * test/test_derivedshapestore.py
59            (TestDerivedShapeStore.assertFloatTuplesEqual)
60            (TestDerivedShapeStore.assertPointListEquals): Rename to
61            assertPointListEquals and change purpose to checking equality of
62            the lists returned by Shape.Points().
63            (TestDerivedShapeStore.test_shape): Use the new
64            assertPointListEquals instead of assertFloatTuplesEqual
65    
66    2003-08-06  Jan-Oliver Wagner <[email protected]>
67    
68            * Thuban/UI/projdialog.py (UTMPanel._OnPropose): Added test for
69            a bounding box. A dialog is raised in case, no bounding box
70            is found. This fixes bug #2043:
71            https://intevation.de/rt/webrt?serial_num=2043
72    
73    2003-08-05  Bernhard Herzog  <[email protected]>
74    
75            * Thuban/Model/color.py (Color.__repr__): Make the repr of a color
76            object look like a Color instantiation. Formerly it looked like a
77            tuple.
78    
79            * test/test_color.py (TestColor.test_repr)
80            (TestColor.test_equality, TestColor.test_inequality): New. test
81            some more apects of the Color class
82            (TestTransparent.test_repr, TestTransparent.test_hex)

84            Transparent object.
85    
86    2003-08-04  Jan-Oliver Wagner <[email protected]>
87    
88            * Doc/manual/thuban-manual.xml: a number of small improvements.
89            The resulting file is the version submitted for GREAT-ER II.
90    
91    2003-08-01  Bernhard Herzog  <[email protected]>
92    
93            * Thuban/UI/resource.py, Thuban/UI/projdialog.py,
94            Thuban/UI/join.py, Thuban/UI/classgen.py, Thuban/UI/about.py,
95            Thuban/Model/resource.py: Insert cvs keywords and doc-strings.

101    2003-08-01  Bernhard Herzog  <[email protected]>
102    
103            First step towards PostGIS integration. More abstraction by movin
104            more code from the layer to the shapestore. More methods of the
105            layer are now simply delegated to the equivalent method of the
106            shapestore. The SHAPETYPE_* constants are now in data not in
107            layer.
108    
109            * Thuban/Model/data.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
110            (SHAPETYPE_POINT, Shape): Move these constants and classes from
111            layer.py to data.py
112            (ShapefileStore.__init__): More Initialization for the new methods
113            and functionality.
114            (ShapefileStore.ShapeType, ShapefileStore.NumShapes)
115            (ShapefileStore.BoundingBox, ShapefileStore.ShapesInRegion)
116            (ShapefileStore.Shape): New methods that were formerly implemented
117            in the layer.
118            (DerivedShapeStore.Shape, DerivedShapeStore.ShapesInRegion)
119            (DerivedShapeStore.ShapeType, DerivedShapeStore.NumShapes)
120            (DerivedShapeStore.BoundingBox): New. DerivedShapeStore
121            equivalents of the new shape methods. These versions are simply
122            delegated to the original shapstore.
123    
124            * Thuban/Model/layer.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
125            (SHAPETYPE_POINT, Shape): Removed. They're now in data.py
126            (Layer.SetShapeStore): Removed the initializatin of instance
127            variables that were needed for the stuff that's now in
128            ShapefileStore
129            (Layer.BoundingBox, Layer.NumShapes, Layer.ShapeType)
130            (Layer.Shape, Layer.ShapesInRegion): Simply delegate to the
131            shapestore.
132    
133            * Thuban/UI/classifier.py, Thuban/UI/renderer.py,
134            Thuban/UI/viewport.py: Import the SHAPETYPE_* constants from data
135            instead of layer.
136    
137            * test/test_shapefilestore.py: New. Tests for ShapefileStore.
138    
139            * test/test_derivedshapestore.py: New. Tests for DerivedShapeStore.
140    
141            * test/test_layer.py: Import the SHAPETYPE_* constants from data
142            instead of layer.
143            (TestLayer.test_derived_store): Remove the test for the exception
144            when instantiating the DerivedShapeStore with an incompatible
145            table which is now in test_derivedshapestore.py. Add some more
146            tests of the layer methods to determine whether they work for a
147            DerivedShapeStore as well.
148    
149    2003-07-31  Jonathan Coles   <[email protected]>
150    
151            * Doc/manual/thuban-manual.xml: Fix the list of required packages
152            by just listing the name and where they can be found.
153    
154    2003-07-31  Frank Koormann   <[email protected]>
155    
156            * Doc/manual/thuban-manual.xml:
157            Changed the screenshot elements to figure.
158            Changed some variablelist elements to itemizedlist.
159            Added section on GDAL formats.
160    
161    2003-07-31  Jonathan Coles   <[email protected]>
162    
163            * Doc/manual/thuban-manual.xml: Added a few sentences about
164            the Fix Border Color option when generating classes.
165    
166    2003-07-30  Jonathan Coles   <[email protected]>
167    
168            * Thuban/Model/classgen.py: Add docstrings. Rename specific
169            Ramp instances to use lower_case_style.
170    
171            * Thuban/UI/classgen.py: Use renamed Ramp instances.
172            
173            * Thuban/UI/classifier.py: Add docstrings.
174    
175            * Thuban/UI/dock.py: Add docstrings.
176    
177            * test/test_classgen.py: Use renamed Ramp instances.
178    
179    2003-07-30  Bernhard Herzog  <[email protected]>
180    
181            * Thuban/Lib/connector.py (QueueingPublisher): Removed. This class
182            was never used in Thuban.
183    
184    2003-07-30  Bernhard Herzog  <[email protected]>
185    
186            * Thuban/UI/join.py (JoinDialog.__init__): Use the table's Title()
187            method directly instead of going through the transient_table
188            method. This faster because transient_table may force the copy of
189            a DBF file into the transient database and setting a table's title
190            doesnm't affect the title of the associated transient table, so
191            this fixes RT #2042
192    
193            * Thuban/UI/main.py (__version__): Don't import the already
194            removed show_exception_dialog.
195    
196    2003-07-29  Jonathan Coles   <[email protected]>
197    
198            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
199            Put back this method and remove the equivalent function since we
200            are setting the exception hook from within this class (OnInit).
201    
202    2003-07-29  Jonathan Coles   <[email protected]>
203    
204            * Doc/manual/images/5_2_custom_ramp.png,

206            Doc/manual/images/5_2_uniform_dist.png,
207            Doc/manual/images/5_2_unique_values.png,
208            Doc/manual/images/8_int_error.png: New screen shots.
209    
210            * Doc/manual/thuban-manual.xml: Fixed typos and wording, clarified

215            * Thuban/Model/data.py: Remove the now unused import of warnings
216    
217    2003-07-29  Bernhard Herzog  <[email protected]>
218    
219            * Thuban/Model/data.py (SimpleStore): Removed. This class has been
220            deprecated since before the 0.8 release and isn't used in Thuban
221            itself anymore.
222    
223            * Thuban/Model/transientdb.py: Remove some unnecessary imports
224    
225    2003-07-29  Jonathan Coles   <[email protected]>
226    
227            * Thuban/UI/application.py (ThubanApplication.OnInit): set the
228            python exception hook here so that we are sure to catch any
229            Thuban exception that happen during initialization.
230    
231            * Thuban/UI/main.py (main): Don't set the exception hook here,
232            it will get set in ThubanApplication.OnInit.
233    
234    2003-07-29  Jonathan Coles   <[email protected]>
235                                                                                
236            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
237            Removed and called it show_exception_dialog() so that the exception
238            handler can be set before the class is created.
239                                                                                
240            * Thuban/UI/main.py (main): Install the exception handler before
241            a ThubanApplication is created.

298    
299            * Thuban/Model/range.py, Thuban/version.py: Remove the #! line as
300            it annoys lintian which warns about these files not being
301            executable. The #1 isn't necessary here since if you absolutely
302            must execute them you can always say "python <filename>".
303    
304            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Remove
305            superfluous code to set brush and pen for point shapes

322            of the manual.
323    
324            * Thuban/UI/renderer.py (MapRenderer.render_map): Wrap method
325            with Begin/EndDrawing() calls to ensure we aren't doing to
326            many updates to the dc during rendering.
327            (ScreenRenderer.draw_shape_layer): self.draw_point_shape takes
328            a pen and brush argument so they need to be passed to the function.
329    
330            * Thuban/UI/viewport.py (ViewPort.calc_min_max_scales): New.
331            Calculates the minimum and maximum scale values. Factored out
332            of set_view_transform so that it could be used to zoom all the
333            way into a single point.
334            (ViewPort.set_view_transform): Call calc_min_max_scales().
335            (ViewPort.FitSelectedToWindow): Zoom to the maximum scale
336            if only a single point is selected.

382            tests. Subscribe to MAP_REPLACED messages too.
383            (ViewPortTest.tearDown): No need to explicitly unsubscribe
384            (ViewPortTest.test_set_map): New test for the SetMap method.
385    
386    2003-07-18  Bernhard Herzog  <[email protected]>
387    
388            * test/test_viewport.py (SimpleViewPortTest.test_default_size):
389            Move this test from ViewPortTest.setUp to this new separate test
390            case. setUp is not the place for the actual tests.
391            (ViewPortTest.test_inital_settings, ViewPortTest.setUp): Move some
392            more of the test from setUp to the new test test_inital_settings.
393            (ViewPortTest.test_win_to_proj, ViewPortTest.test_proj_to_win)
394            (ViewPortTest.test_proj_conv): Split test_proj_conv into
395            test_win_to_proj and test_proj_to_win and make the tests easier to
396            understand
397            (ViewPortTest.testFitRectToWindow, ViewPortTest.testZoomFactor)
398            (ViewPortTest.testZoomOutToRect, ViewPortTest.testTranslate)

406    
407    2003-07-18  Bernhard Herzog  <[email protected]>
408    
409            * test/runtests.py: The test suite can now be run without an X
410            connection. To make sure this remains true, remove the DISPLAY
411            environment variable so that an error occurs if the wxGTK is
412            imported accidentally
413    
414    2003-07-18  Bernhard Herzog  <[email protected]>
415    
416            * Thuban/UI/viewport.py: Remove unused imports
417    
418            * Thuban/UI/view.py: Remove unused imports

420    2003-07-18  Bernhard Herzog  <[email protected]>
421    
422            * test/test_export.py Remove unused imports. The OutputTransform
423            function is now in viewport.py and is called output_transform
424            (TestScalebar.test_output_transform)
425            (TestScalebar.test_OutputTransform): Renamed to
426            test_output_transform and updated to use output_transform instead
427            of OutputTransform
428    
429            * Thuban/UI/view.py (OutputTransform): Moved to viewport.py and
430            renamed.
431            (MapCanvas.Export, MapPrintout.draw_on_dc): OutputTransform was
432            renamed to output_transform

438    
439            * Thuban/Model/layer.py (Layer.__init__): Rename
440            classificationField to classificatin_column and init it here so
441            that it can be used in SetClassificationColumn
442            (Layer.GetClassificationColumn, Layer.GetClassificationField):
443            Rename to GetClassificationColumn.
444            (Layer.SetClassificationColumn, Layer.SetClassificationField):
445            Rename to SetClassificationColumn and issue a LAYER_CHANGED
446            message if the column changes.
447            (Layer._classification_changed, Layer.ClassChanged): Rename to
448            _classification_changed. Update the callers.
449            (Layer.SetShapeStore): Further field->column renames.
450    
451            * Thuban/Model/load.py (SessionLoader.start_classification)
452            (SessionLoader.start_clpoint): Updates because of
453            field->column method name changes in the Layer class
454    
455            * Thuban/Model/save.py (SessionSaver.write_classification): Updates
456            because of field->column method name changes in the Layer class
457    
458            * Thuban/UI/classifier.py (Classifier.__init__)

466            of field->column method name changes in the Layer class
467    
468            * test/test_save.py (SaveSessionTest.testClassifiedLayer)
469            (SaveSessionTest.testClassifiedLayer): Update because of
470            field->column method name changes in the Layer class
471    
472            * test/test_layer.py (SetShapeStoreTests.setUp)
473            (SetShapeStoreTests.test_sanity): Update because of field->column
474            method name changes in the Layer class
475            (TestLayerModification.setUp): Subscribe to LAYER_CHANGED as well

477            (TestLayerModification.test_initial_settings): remove unsued code
478            and rename to test_sanity.
479            (TestLayerModification.test_set_classification): New test for
480            SetClassification and SetClassificationField.
481    
482    2003-07-18  Bernhard Herzog  <[email protected]>
483    
484            * test/test_classgen.py (TestFixedRamp.test): Extend test to check
485            the non-fixed values as well. The old test would have accepted a
486            fixed ramp that only returnes the fixed properties
487    
488    2003-07-17  Jonathan Coles   <[email protected]>
489    
490            * Doc/manual/mainwindow.png, Doc/manual/mainwindow.xcf: Screen
491            shots for the manual. The XCF file is the source image and
492            has additional layers to support changes.
493    
494            * Doc/manual/thuban-manual.xml: Wrote an initial Introduction.
495    
496            * Thuban/UI/classifier.py (Classifier.__BuildClassification):
497            Return both the new class and the field name.
498    
499            * Thuban/UI/mainwindow.py (MainWindow.ToggleLegend): Don't
500            fit the map to the window as this changes any zoom level that
501            the user may have set.
502    
503    2003-07-16  Jonathan Coles   <[email protected]>
504    
505            * Thuban/Model/classgen.py (generate_singletons,
506            generate_uniform_distribution, generate_quantiles): Remove
507            fixes parameter, but maintain the same functionality by having
508            the calling function pass a FixedRamp object for the ramp.
509            (FixedRamp): New. Adapts a ramp to have fixed property values.
510    
511            * Thuban/Model/classification.py: Use new CLASS_CHANGED message.
512            (Classification): Inherit from Publisher.
513            (Classification.__init__): Remove the layer parameter.
514            Classifications no longer need to have a parent layer.
515            (Classification.GetField, Classification.GetFieldType,
516            Classification.SetFieldInfo): Removed. The field name is stored
517            in the layer, and the type can be retreived by calling
518            Layer.GetFieldType().
519            (Classification._set_layer, Classification.GetLayer): Removed.
520            Classifications no longer have a parent layer.
521    
522            * Thuban/Model/layer.py (Layer.Destroy): Unsubscribe from the
523            classification.
524            (Layer.SetShapeStore): Reset the classification first while
525            we still have the old shape store to work with.
526            (Layer.GetClassificationField, Layer.SetClassificationField):
527            New. Method for getting/setting the field to classify on.
528            (Layer.SetClassification): Simplified now that the layer
529            simply has to hold a reference to the classification and not
530            tell the classification who owns it.
531            Fixes RTbug #2023.
532    
533            * Thuban/Model/load.py (SessionLoader.start_classification):
534            Set the field name on the layer, not the classification.
535    
536            * Thuban/Model/messages.py: Add CLASS_CHANGED for when a
537            classification is modified.
538    
539            * Thuban/Model/save.py (SessionSaver.write_classification):
540            Get the field name and type from the layer.
541    
542            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Renamed
543            parameter records to rows and add docstring. Fixes RTbug #1997.
544    
545            * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Use a fixed
546            ramp when we need to fix certain values of a ramp rather than
547            using the old fixes parameter. Fixes RTbug #2024.
548    
549            * Thuban/UI/classifier.py (ClassGrid.CreateTable): Add fieldType
550            parameter.
551            (ClassTable.Reset): Add fieldType parameter and use it, rather
552            than asking the classification.
553            (Classifier.__init__): Remember the original class's field
554            and ask the layer for the field type, rather than the classification.
555            (Classifier.__SetGridTable): Retrieve the field and field type
556            for the table because they are not in the classification.
557            (Classifier._OnTry, Classifier._OnRevert): Set the classification
558            field on the layer in addition to the classification itself.
559    
560            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Get the
561            classification field from layer.
562    
563            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Get the
564            classification field from layer. Split up tests and remove
565            *-imports. Fixes RTbug #1992.

568    
569            * test/test_classification.py
570            (TestClassification.test_classification): Remove tests for methods
571            that no longer exist.
572    
573            * test/test_layer.py (SetShapeStoreTests.setUp): Classification
574            __init__ no longer has a field parameter, use SetClassificationField.
575            (SetShapeStoreTests.test_sanity): Use layer object to get class
576            field info.
577    
578            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Use
579            SetClassificationField on layer to set class field info.
580    
581            * test/test_viewport.py: Renamed from test/test_view.py.
582    
583    2003-07-16  Jan-Oliver Wagner <[email protected]>
584    
585            * Doc/manual/thuban-manual.xml: Added authors and an initial
586            coarse structure.
587    
588    2003-07-15  Bernhard Herzog  <[email protected]>
589    
590            * test/support.py (FloatComparisonMixin): This is a mix-in class
591            and therefore should not be derived from any other class.
592    
593            * test/test_range.py (RangeTest): FloatComparisonMixin is a
594            mix-in, so derive from TestCase as well.
595    
596    2003-07-15  Bernhard Herzog  <[email protected]>
597    
598            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Rework the
599            draw_func handling a bit to remove one layer of indirection. This
600            makes the renderer about 10% faster in the non-classifying case
601            and the code a bit cleaner
602            (MapRenderer.draw_point_shape): Add the pen and brush parameters
603            and set them in the dc. Now the draw_point_shape method and
604            wxproj's draw_polygon_shape function have basically the same
605            signature so that both can be directly used as draw_func
606    
607    2003-07-15  Bernhard Herzog  <[email protected]>
608    
609            * Thuban/Model/save.py (SessionSaver.write_classification): Encode
610            string values (in addition to the labels) as UTF 8
611    
612            * Thuban/Model/load.py (SessionLoader.start_clpoint): Decode the
613            values if the field type is string
614    
615            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Test
616            saving a session with non-ascii string classification values.
617    
618            * test/test_load.py (TestClassification.file_contents)
619            (TestClassification.test): Check for non-ascii values in string
620            classifications
621    
622    2003-07-14  Jonathan Coles   <[email protected]>
623    
624            * test/test_view.py: New. Tests for ViewPort.
625    
626    2003-07-14  Frank Koormann   <[email protected]>
627    
628            * Thuban/Model/load.py (SessionLoader.start_map): Encode map
629            title to latin1.  Fixes https://intevation.de/rt/webrt?serial_num=2013

635    2003-07-10  Jonathan Coles   <[email protected]>
636    
637            * Thuban/UI/viewport.py (Tool.MouseUp): Should have called
638            drag_stop, not drag_move when the mouse is released.
639    
640    2003-07-10  Jonathan Coles   <[email protected]>
641    
642            The most important part of this is the seperation of view.py into
643            two pieces. viewport.py now has a class called ViewPort which
644            contains all the non-wx parts of view.py and can therefore be
645            tested. view.py contains only the wx-specific parts and is fairly
646            simple.
647    
648            * Thuban/UI/view.py: Stripped out all non-wx functionality. Fixes
649            RTTbug #1992.
650            * Thuban/UI/viewport.py: New. Contains non-wx view functionality.
651            RTTbug #1992.

653            * Thuban/Model/classgen.py (generate_singletons,
654            generate_uniform_distribution, generate_quantiles):
655            Added 'fixes' parameter so that property attributes can
656            be held constant over the generated classification groups.
657            (CustomRamp.GetProperties): Remove unused variables.
658    
659            * Thuban/Model/map.py (Map.SetProjection): Send the old
660            projection as an argument to listeners of the MAP_PROJECTION_CHANGED
661            event.
662    
663            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Added 'records'
664            parameter which is a list of records that restricts which
665            records are saved. Fixes RTbug #1997.
666    
667            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
668            Port exception dialog from GREAT-ER. Fixes RTbug #1993.
669    
670            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Add controls
671            to allow the user to fix line color/width on generated groups.
672            (ClassGenDialog.OnOK): Use new 'fixes' parameter of the generate_*
673            functions to optionally fix group properties.
674    
675            * Thuban/UI/main.py (main): Set exception hook to the
676            ShowExceptionDialog. Fixes RTbug #1993.
677    
678            * Thuban/UI/mainwindow.py (MainWindow.ShowTableView): Raise
679            the table window when it is selectd to be shown.
680

682            Export Selection button and move the export buttons underneath
683            the table.
684            (QueryTableFrame.UpdateStatusText): Added event argument so
685            that it can respond to grid selection events. The status text
686            is now updated even when the table is not associated with a
687            layer as was previously assumed.
688            (QueryTableFrame.OnGridSelectRange, OnGridSelectCell): Removed.
689            UpdateStatusText responds to these events.
690            (QueryTableFrame.OnSaveAs): Renamed to doExport.
691            (QueryTableFrame.doExport): Helper function that saves the
692            entire table, or selected rows, to a file.
693            (QueryTableFrame.OnExport, QueryTableFrame.OnExportSel): New.
694            Respond to export button events and call doExport.
695    
696            * extensions/thuban/gdalwarp.cpp (ProjectRasterFile): Make sure
697            the function doesn't return NULL without first setting a Python
698            Error.
699    
700            * test/runtests.py (main): Only print "Unknown option" for
701            unsupported options.
702    
703            * test/support.py (FloatComparisonMixin.assertFloatEqual): Take
704            optional epsilon argument to specify floating point accuracy.
705            (FloatComparisonMixin.assertFloatSeqEqual): Call assertFloatEqual
706            for each item test.
707    
708            * test/test_csv_table.py (TestCSVTable.test_table_to_cvs): Add
709            tests for saving selected records.
710    
711            * test/test_dbf_table.py (TestTableToDBF.test_table_to_dbf): Add
712            tests for saving selected records.
713    
714            * test/test_map.py (TestMapWithContents.test_set_projection):
715            MAP_PROJECTION_CHANGED events send the old projection.
716    
717            * test/test_session.py
718            (TestSessionWithContent.test_forward_map_projection):
719            MAP_PROJECTION_CHANGED events send the old projection.
720    
721            * test/test_table.py (TableTest): Update tests to use non-deprecated
722            functions.
723    
724    2003-07-08  Bernhard Herzog  <[email protected]>
725    
726            * Thuban/Model/transientdb.py (TransientTableBase.Width): The type
727            constants in the column objects are the standard ones defined in
728            the table module.
729    
730            * test/test_transientdb.py
731            (TestTransientTable.test_transienttable_to_dbf): New. Test whether
732            exporting transient tables as DBF works. This should catch the bug
733            just fixed in TransientTableBase.Width.
734    
735    2003-07-08  Bernhard Herzog  <[email protected]>
736    
737            * Thuban/Model/classgen.py (CustomRamp.GetProperties): Compute the
738            interpolated colors correctly.
739    
740            * test/test_classgen.py (TestCustomRamp.test_color_interpolation):
741            New. Test case for the fix in classgen.py
742    
743    2003-07-08  Bernhard Herzog  <[email protected]>
744    
745            * test/runtests.py (main): Make the default output less verbose
746            and add a verbosity option (-v) to get the old output
747    
748    2003-07-08  Bernhard Herzog  <[email protected]>
749    
750            * Resources/XML/thuban-0.9.dtd: New. This will become the DTD for

811    2003-07-03  Bernhard Herzog  <[email protected]>
812    
813            * Thuban/Model/transientdb.py (TransientJoinedTable.__init__):
814            Update doc-string
815            (TransientJoinedTable.create): Do not modify the column objects of
816            the input tables in place and copy all columns of the input tables
817            into the joined table after all.
818    
819            * test/test_transientdb.py
820            (TestTransientTable.test_transient_joined_table_same_column_name):

826    
827    2003-07-02  Jonathan Coles   <[email protected]>
828    
829            * Thuban/Model/classgen.py (generate_singletons,
830            generate_uniform_distribution, generate_quantiles,
831            GenQuantiles0): Make sure maxValue isn't less than
832            one, otherwise we could divide by zero.
833    
834            * test/test_classgen.py (ClassGenTest.doClassRangeTest,
835            ClassGenTest.doClassSingleTest): Call doBoundsTest to
836            check the end classification groups against the
837            proper property values.
838            (ClassGenTest.doBoundsTest): New. Checks the first and
839            last classification groups to make sure their properties
840            are the correct upper and lower bounds for a color ramp.
841    
842    2003-07-02  Jonathan Coles   <[email protected]>
843    
844            * Thuban/Model/classgen.py (generate_singletons,
845            generate_uniform_distribution, generate_quantiles,
846            GenQuantiles0): The denominator was one to high when
847            calculating the index for the ramp causing the index
848            to never to reach one.
849    
850    2003-07-02  Jonathan Coles   <[email protected]>
851    
852            Changed the singature of ClassGroupRange.__init__ and
853            ClassGroupRange.SetRange() so that the min/max values are
854            passed as a tuple. This makes a better calling scheme for
855            when a Range object is passed instead.
856    
857            * Thuban/Model/classgen.py: Fixed parameters to
858            ClassGroupRange constructor.
859    
860            * Thuban/Model/classification.py (ClassGroupRange.__init__):
861            Consolidate the min/max parameters into a single _range which
862            can either be a tuple or a Range object.
863            (ClassGroupRange.SetRange): Consolidate the min/max parameters
864            into a single _range which can either be a tuple or a Range object.
865    
866            * Thuban/Model/load.py (SessionLoader.start_clrange): Fix
867            call to ClassGroupRange constructor to use a tuple.
868    
869            * Thuban/Model/layer.py (Layer.SetClassification): Switch
870            the classification instance variable to the new class
871            before calling _set_layer otherwise subscribers to a
872            LAYER_CHANGED event will not see any difference.
873    
874            * test/test_classification.py: Fix tests of ClassGroupRange
875            so that they use the new signature.
876    
877            * test/test_load.py: Fix use of ClassGroupRange so that it
878            uses the new signature.
879    
880            * test/test_load_0_2.py: Fix use of ClassGroupRange so that it
881            uses the new signature.
882    
883            * test/test_save.py: Fix use of ClassGroupRange so that it
884            uses the new signature.

887    2003-07-01  Jonathan Coles   <[email protected]>
888    
889            * Thuban/Model/classgen.py: Fixes RTbug #1972, 1971.
890            Import used objects/class from color.
891            (generate_singletons): We don't
892            need the numGroups parameter anymore because we are using
893            the new ramps with GetProperties().
894            (generate_uniform_distribution): Use new ramp method
895            GetProperties().
896            (generate_quantiles, GenQuantiles0): Use new ramp method
897            GetProperties().
898            (CustomRamp.SetNumGroups): Removed. The ramps now map
899            a value from 0 to 1 to class properties so the number
900            of groups is not needed ahead of time.
901            (CustomRamp.next): Removed. CustomRamp does not support
902            interation anymore.
903            (CustomRamp.GetProperties): Returns a ClassGroupProperties
904            object based on the index value from 0 to 1 that is
905            passed to it.
906            (GreyRamp, RedRamp, GreenRamp, BlueRamp, GreenToRedRamp):
907            Made into instances of Monochromatic class instread of
908            deriving from it.
909            (HotToCold.SetNumGroups): Removed. See CustomRamp.
910            (HotToCold.next): Removed. See CustomRamp.
911    
912            * Thuban/Model/classification.py: Fixes RTbug #1973, 1971.
913            (Classification.SetField, Classification.SetFieldType):
914            Replaced with SetFieldInfo.
915            (Classification.SetFieldInfo): New. Does a better job of
916            what SetField and SetFieldType used to do by combining
917            their function since they should really always be done
918            at the same time.
919            (Classification.SetLayer): Renamed to _set_layer.
920            (Classification._set_layer): Should only be called from
921            Layer's SetClassification. This does not cause a recursive
922            call as SetLayer did because we know that Layer knows about
923            the classification.
924    
925            * Thuban/Model/color.py: Fixes RTbug #1971.
926            (_Transparent): Renamed from Transparent so it doesn't
927            conflict with the module variable.
928            (Transparent, Black): Renamed from Color.Transparent,
929            Color.Black so they are not class variables.
930    
931            * Thuban/Model/layer.py: Fixes RTbug #1971, 1973.
932            (Layer.Destroy): We don't need to call SetClassification
933            anymore to clear out the back reference in the classifcation
934            to the layer. It's better to set it to None using _set_layer,
935            and we won't be creating another clas object too.
936            (Layer.SetClassification): Classification._set_layer is not
937            recursive so remove all the locking variables. Also clean
938            up the code so that it remains unchanged if something fails.
939    
940            * Thuban/Model/load.py: Fixes RTbug #1971.
941            (SessionLoader.start_classification): Call
942            Classification.SetFieldInfo().
943    
944            * Thuban/Model/save.py: Removed import of Color which wasn't
945            being used.
946    
947            * Thuban/UI/classgen.py: Fixes RTbug #1972.
948            (ClassGenDialog.__init__): Color ramps are now instances
949            already so we don't need to create any new objects.
950            (ClassGenDialog.OnOK): Check for numGroups is no longer
951            necessary because we never use it.
952    
953            * Thuban/UI/classifier.py: Fixes RTbug #1971.
954            (Classifier.__BuildClassification, Classifier.__SetGridTable):
955            Call Classification.SetFieldInfo() instead of SetFieldType.
956    
957            * Thuban/UI/renderer.py: Fixes RTbug #1971.
958    
959            * Thuban/UI/view.py: Fixes RTbug #1974, 1971.
960            (MapCanvas.__init__): Subscribe to the idle time event. Set
961            background color to white.
962            (MapCanvas.OnPaint): Set a flag indicating that we should
963            render the map during idle time. If we already have a bitmap
964            just draw it now.
965            (MapCanvas.OnIdle): New. Render the map only during idle time.
966            This also fixes a problem with the busy cursor under gtk.
967    
968            * test/test_classgen.py (ClassGenTest.test_generate_singletons):
969            Fix calls to generate_singletons because the signature changed.
970    
971            * test/test_classification.py: Fix color references and
972            change calls to Classification.[SetField|SetFieldType] to
973            SetFieldInfo.
974    
975            * test/test_load.py: Fix color references.
976    
977            * test/test_load_0_2.py: Fix color references.
978    
979            * test/test_save.py (SaveSessionTest.testClassifiedLayer):
980            Change calls to Classification.[SetField|SetFieldType] to
981            SetFieldInfo.
982

988            (TestTransientTable.test_transient_joined_table_with_equal_column_names):
989            New. Test join of two tables with partly equal column names.
990    
991            * Thuban/Model/transientdb.py (TransientJoinedTable.create):
992            If duplicates in left and right tables column names are found,
993            append '_' (underscores) to the name until it is unique.
994            Create always new internal names for the resulting table and reference
995            columns in the join statement with <table>.<column>

1002            tables works.
1003            
1004            * Thuban/Model/transientdb.py (TransientJoinedTable.create): Make
1005            sure to use the right internal names even when joining on field
1006            with the same names in both tables. Also, detect duplicate names
1007            in the joined table correctly.
1008

1017            and splits it into a tuple of at most three integers.
1018            Used make_tuple() to make tuple versions of the version
1019            numbers.
1020    
1021            * Thuban/UI/about.py: Add Thuban email addresses.

1051            Reset the status of the buttons as the situation warrants,
1052            but in a better more reliable way by not relying on the
1053            current status to determine what needs to change.
1054    
1055            * Thuban/UI/main.py (wxCHECK_VERSION): Removed. Not needed.
1056            (verify_versions): Remove most of the code since it is

1072    2003-06-25  Jonathan Coles   <[email protected]>
1073    
1074            * Thuban/UI/classifier.py (Classifier.EditSymbol): The parent
1075            of the SelectPropertiesDialog should be self so the window
1076            appears on top.
1077            (ClassGroupPropertiesCtrl.DoEdit): The parent
1078            of the SelectPropertiesDialog should be self so the window
1079            appears on top.

1102    
1103            * setup.py: Don't include Locale resources yet as we don't

1105            for Windows. Update version to 0.8.0.
1106    
1107            * Doc/thuban.dtd: Removed since it is now in Resources/XML.
1108    
1109            * Thuban/UI/mainwindow.py: Add blank line at the end because
1110            file was not being read correctly building the Windows

1126            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxBeginBusyCursor()
1127            directly to avoid the wxSafeYield() call which generates an
1128            OnPaint event causing infinite recursion. Don't try to catch
1129            exception anymore. This was for before there were limits on map
1130            scaling.

1132    2003-06-23  Bernhard Herzog  <[email protected]>
1133

1137            Register DerivedShapestores with the session
1138    
1139            * Thuban/Model/session.py (Session.Tables): Make sure each table
1140            is only listed once.
1141    
1142            * test/test_load.py (TestJoinedTable.test): Add check_format call.
1143            Update file contents to match the one written out.
1144    
1145    2003-06-20  Bernhard Herzog  <[email protected]>
1146    
1147            * test/xmlsupport.py (SaxEventLister.startElementNS)
1148            (SaxEventLister.endElementNS): Do not include the qname. Python
1149            2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
1150            is (presumably incorrectly) None, whereas it's a string with the
1151            element name in the later versions.
1152    
1153            * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
1154            (TestEventList.test_even_list_namespace): Update tests to reflect

1160            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
1161            by deriving classes to determine if that layer supports shapes.
1162            (Layer): Override HasShapes and return true.
1163    
1164            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
1165            instead of a direct call to wx[Begin|End]CusyCursor().
1166            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
1167            table data.
1168    
1169            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
1170            New. Wrappers around the wxWindows functions that allow us to
1171            make additional calls such as wxYield which gives the native
1172            system a chance to update the cursor correctly.
1173    
1174            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
1175            instead of a direct call to wx[Begin|End]CusyCursor().
1176    
1177            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
1178            instead of a direct call to wx[Begin|End]CusyCursor().
1179            (MapCanvas.find_shape_at): Check if the current search layer
1180            support shapes, otherwise go on to the next layer.
1181    
1182            * test/test_layer.py: Add tests in each type of layer for
1183            HasClassification() and HasShapes()
1184    
1185    2003-06-20  Jonathan Coles   <[email protected]>
1186    
1187            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
1188            turning on the busy cursor to allow the system to change the
1189            cursor before we begin painting. This fixes a problem that
1190            was occuring only under GTK. Fixes RTbug #1840.
1191    
1192    2003-06-20  Bernhard Herzog  <[email protected]>
1193    
1194            * Resources/XML/thuban-0.8.dtd: New DTD for the new file format
1195            version.
1196    
1197            * Thuban/Model/save.py (sort_data_stores): New. Make topological
1198            sort of the data sources so they can be written with sources that
1199            data sources that depend on other data sources come after the
1200            sources they depend on.
1201            (SessionSaver.__init__): Add idmap instance variable to map from

1209            containers.
1210            (SessionSaver.write_layer): Layer elements now refer to a

1225            addition to filename.
1226            (SessionLoader.start_table, SessionLoader.end_table): Removed.
1227            They were never used in the old formats and aren't needed for the
1228            new.
1229    
1230            * Thuban/Model/session.py (Session.DataContainers): New method to
1231            return all "data containers", i.e. shapestores and tables

1267            data stores for writing.
1268    
1269            * test/runtests.py: Add CVS keywords
1270    
1271    2003-06-20  Jonathan Coles   <[email protected]>
1272    
1273            * test/test_session.py
1274            (UnreferencedTablesTests.test_unreferenced_tables_with_joins):
1275            Use the cultural_landmark-point.dbf file for the store so that
1276            the table rows and shape count match.
1277    
1278    2003-06-20  Jonathan Coles   <[email protected]>
1279    
1280            * Thuban/Model/data.py (DerivedShapeStore.__init__): Raise
1281            an exception if the number of shapes is different from the
1282            number of rows in the table. Address RTbug #1933.
1283    
1284            * test/test_layer.py (TestLayer.test_derived_store): Add
1285            a test for the new exception in DerivedShapeStore.__init__.
1286    
1287            * test/support.py (FloatTestCase): Removed since there is
1288            already FloatComparisonMixin. Fixes RTbug #1954.
1289            (FloatComparisonMixin.assertFloatEqual): Include test for
1290            infinity that was part of FloatTestCase.
1291    
1292            * test/test_range.py (RangeTest): Inherit from
1293            support.FloatComparisonMixin now that we don't have
1294            support.FloatTestCase.
1295    
1296    2003-06-20  Bernhard Herzog  <[email protected]>
1297    
1298            * test/test_save.py (SaxEventLister, sax_eventlist): Removed. Use
1299            the implementation in xmlsupport instead.
1300            (SaveSessionTest.compare_xml): sax_eventlist is now in xmlsupport
1301    
1302            * test/test_proj.py: Import sax_eventlist from xmlsupport instead
1303            of test_save
1304    
1305    2003-06-20  Bernhard Herzog  <[email protected]>
1306    
1307            * test/test_load.py (LoadSessionTest.check_format): New helper
1308            method to make sure the test files we load might have been written
1309            by the current thuban version.
1310            (ClassificationTest.TestLayers, TestSingleLayer.test)
1311            (TestLayerVisibility.test, TestClassification.test)
1312            (TestLabels.test, TestLayerProjection.test, TestRasterLayer.test):
1313            Add check_format() calls and fix the thuban data to match the data
1314            that would be written by saving the session loaded from it.
1315    
1316            * test/xmlsupport.py (SaxEventLister, sax_eventlist): Copies of
1317            the same class and function in test_save.
1318    
1319            * test/test_xmlsupport.py (TestEventList): New. test cases for
1320            sax_eventlist
1321    
1322    2003-06-20  Bernhard Herzog  <[email protected]>
1323    
1324            * Resources/XML/thuban.dtd: Add comment about which versions of
1325            Thuban are covered by this DTD
1326            (map): Fix content model for layers and raster layers. There can
1327            be any number or layers and raster layers in any order.
1328    
1329    2003-06-20  Jonathan Coles   <[email protected]>
1330    
1331            This is mainly about fixing RTbug #1949.
1332    
1333            * Thuban/Model/classification.py: Remove "from __future__"
1334            import statement since python 2.2 is the earliest supported
1335            version.
1336    
1337            * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
1338            Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES
1339            depending on the units this projection *forwards* into.
1340    
1341            * Thuban/Model/save.py (SessionSaver.write_classification):
1342            Remove unnecessary use of lambdas and nested functions.
1343    
1344            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Do scale
1345            adjustment here if the map projection uses degrees.
1346    
1347            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
1348            scale adjust code since it is now done before calling
1349            this method. Don't do anything if the map projection
1350            is None.
1351    
1352    2003-06-19  Bernhard Herzog  <[email protected]>
1353    
1354            Move version specific load tests to their own file.
1355    
1356            * test/test_load.py: Expand the doc-string to explain a bit how to
1357            handle file format changes.
1358            (TestClassification.test): Update the docstring as this test is
1359            not about Thuban 0.2 anymore.
1360    
1361            * test/test_load_0_2.py: New file with the load tests for thuban
1362            files created with Thuban 0.2 and earlier.
1363    
1364    2003-06-19  Bernhard Herzog  <[email protected]>
1365    
1366            Add XML validation to some of the tests. Validation will only be
1367            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
1368            To make the DTD available to the test cases it's moved into
1369            Resources/XML
1370    
1371            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
1372            for versions up to and including 0.2. Two slight changes: added an
1373            encoding specification and fixed the comment which refered to
1374            GRASS, not Thuban
1375    
1376            * test/xmlsupport.py: New support module for tests involving XML.
1377            Currently there's a mix-in class for XML validation.
1378    
1379            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
1380    
1381            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
1382            so that we can validate the
1383            (SaveSessionTest.testEmptySession)
1384            (SaveSessionTest.testSingleLayer)
1385            (SaveSessionTest.testSingleLayer)
1386            (SaveSessionTest.testLayerProjection)
1387            (SaveSessionTest.testRasterLayer)
1388            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
1389    
1390            * test/runtests.py (main): Call print_additional_summary instead
1391            of print_garbage_information
1392    
1393            * test/support.py (resource_dir): New function to return the
1394            "Resource" subdirectory
1395            (print_additional_summary): New function to combine several
1396            summary functions
1397            (run_tests): Use print_additional_summary instead of calling
1398            print_garbage_information directly
1399    
1400    2003-06-19  Bernhard Herzog  <[email protected]>
1401    
1402            * Doc/thuban.dtd (classification): Correct the content model of
1403            the classification element.
1404            (projection): Add the "name" attribute
1405    
1406    2003-06-19  Frank Koormann   <[email protected]>
1407    
1408            MERGE from the greater-ms3 branch.
1409    
1410            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
1411            scale if projection is latlong to get better estimate.
1412    
1413            Fix problem of hidden properties dialog under windows after double
1414            click on layer tree:
1415            The tree control always gets an Expanded / Collapsed event after
1416            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
1417            raises the already displayed window.
1418    
1419            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
1420            raiseProperties initialized to prevent endless loops
1421            (LegendTree._OnItemActivated): Depending on self.raiseProperties
1422            simply raise the properties or open the dialog and issue a second
1423            event.
1424    
1425    2003-06-18  Jonathan Coles   <[email protected]>
1426    
1427            * setup.py: Fix a few problems that occured under Windows.
1428    
1429    2003-06-18  Jonathan Coles   <[email protected]>
1430    
1431            When Thuban loaded the map was redrawn twice because the
1432            legend was being opened after the mainwindow was created
1433            and not during its creation. This meant the map was drawn
1434            initially and then had to be redrawn when the legend
1435            caused the display to change. Now the legend is opened
1436            in the mainwindow constructor which resolves this issue.
1437    
1438            Also, although we were checking for the existence of
1439            gdal and gdalwarp modules, the gdalwarp extension was
1440            still being compiled (which may fail if the system doesn't
1441            have gdal installed). the build_ext command to setup.py
1442            now accepts the flags --with-gdal and --without-gdal.
1443            If --without-gdal is specified setup.py will try to
1444            use the gdal parameters specified by gdal-config. Under
1445            windows, those parameters have to be set in setup.py
1446            as with proj4 an wxWindows.
1447    
1448            * setup.py: Use a list instead of seperate variables for
1449            extension parameters so we can create a generic function
1450            that runs an appropriate *-config script.
1451            (run_cs_script): Renamed from run_wx_script and modified
1452            to accept a second argument which is a list of lists to
1453            be filled in by the values returned from running the command.
1454            (thuban_build_ext): New. Extends the build_ext command and
1455            provides the options --with-gdal/--without-gdal which then
1456            optionally includes the gdalwarp extension.
1457    
1458            * Thuban/Model/resource.py: First check if we can import
1459            the gdalwarp Thuban extension before checking for gdal.
1460            Also added some comments.
1461            
1462            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
1463            the map is None which may be the case if none has been loaded
1464            yet.
1465    
1466            * Thuban/UI/main.py (main): Remove call to ShowLegend.
1467    
1468            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
1469    
1470            * Thuban/UI/renderer.py: Check for gdal support before importing
1471            gdalwarp.
1472            (MapRenderer.render_map): Only try to optimize if we have gdal
1473            support otherwise nothing will get drawn.
1474    
1475            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
1476            during startup before a map has been created. Check if map is None
1477            before using it and do nothing if it is.
1478    
1479    2003-06-17  Jonathan Coles   <[email protected]>
1480    
1481            Fix the problem with raster layers under Windows that caused
1482            Thuban to crash. The view should respond to layer projection
1483            changed events to update the display. Changes to a projection
1484            should not cause the map to be set to full extent.
1485            
1486            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
1487            current_map_proj to remember the current map projection so that
1488            when the projection changes we know what the previous projection
1489            was.
1490            (MapCanvas.SetMap): Unsubscribe and subscribe to
1491            LAYER_PROJECTION_CHANGED events.
1492            (MapCanvas.projection_changed): Split into two methods that respond
1493            to map and layer projection changes.
1494            (MapCanvas.map_projection_changed): New. Takes the current view and
1495            projects it using the new projection. This does not cause the
1496            map to be redrawn at full extent.
1497            (MapCanvas.layer_projection_changed): New. Cause a redraw which
1498            will draw each layer in its new projection.
1499            
1500            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
1501            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
1502            under Windows.
1503            
1504            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
1505            to twice sizeof(void*) because there are two digits for each
1506            hex byte.
1507    
1508    2003-06-16  Bernhard Herzog  <[email protected]>
1509    
1510            Update to the layer interface: Direct access to the table,
1511            shapetable, shapefile and filename attributes is now actively
1512            deprecated by issuing deprecation warnings for all places where
1513            this happens.
1514    
1515            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
1516            to the instance variables table, shapetable, shapefile and
1517            filename via __getattr__ so that we can issue a deprecation
1518            warning.
1519            (Layer.SetShapeStore): Don't set the deprecated instance variables
1520            any more
1521            (Layer.SetShapeStore): Don't use deprecated layer instance
1522            variables
1523            (Layer.Destroy): No need to explicitly remove the instance
1524            variables any more
1525            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
1526            instance variables
1527    
1528            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
1529            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
1530            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
1531            use deprecated layer instance variables
1532    
1533            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
1534            deprecated layer instance variables
1535    
1536            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
1537            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
1538            instance variables
1539

1541            deprecated layer instance variables
1542

1548    
1549            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)

1551            variables
1552    
1553            * test/runtests.py (main): Turn Thuban's deprecation warnings into
1554            errors so that they're cought by the tests
1555    
1556            * test/test_load.py (TestSingleLayer.test): Don't use deprecated

1558    
1559    2003-06-16  Jonathan Coles   <[email protected]>
1560    
1561            Fix a problem under Windows whereby if the user double-clicks on a
1562            layer in the legend that tree item will expand or collapse as well
1563            as open the layer properties dialog. The state of the tree item
1564            should not be affected.
1565    
1566            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
1567            preventExpandCollapse and subscribe to expanding and collapsing
1568            events.
1569            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
1570            collapsing events and will veto the event if it has been triggered
1571            by the user double clicking on a layer.
1572            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
1573            that an expanding/collapsing event should be vetoed.
1574    
1575    2003-06-13  Bernhard Herzog  <[email protected]>
1576    
1577            * Thuban/UI/classifier.py (Classifier.OnClose)
1578            (Classifier.map_layers_removed)
1579            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
1580            in OnClose and not in map_layers_removed or
1581            layer_shapestore_replaced to make sure it always happens when the
1582            dialog is closed
1583    
1584    2003-06-13  Jonathan Coles   <[email protected]>
1585    
1586            This puts back a fix for Windows where a panel is needed so that
1587            the background of the table view appears correctly.
1588    
1589            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
1590            object that can be used by derived classes to place any
1591            controls (including the grid) onto.
1592            (QueryTableFrame.__init__): Use the panel as the parent window
1593            for all the controls. Reparent the grid so that the panel is
1594            the parent. Call UpdateStatusText() to correctly initialize
1595            the status bar.
1596    
1597    2003-06-13  Jonathan Coles   <[email protected]>
1598    
1599            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
1600            from wxFrame (as opposed to wxDialog like the other classes)
1601            but otherwise behaves like the other classes. This is needed
1602            for the TableView which isn't really a dialog and needs to
1603            have a status bar and control buttons.
1604    
1605            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
1606            instance variable to keep track of how many rows are selected.
1607            Subscribe once to the the events we are interested in.
1608            (ThubanGrid.OnRangeSelect): Only handle event if event handling
1609            hasn't been turned off.
1610            (ThubanGrid.OnSelectCell): Only handle event if event handling
1611            hasn't been turned off.
1612            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
1613            as an event listener (which changes the event handler stack)
1614            simply set an instance variable to False. This is checked in
1615            the event handlers.
1616            (ThubanGrid.GetNumberSelected): Return the number of currently
1617            selected rows.
1618            (TableFrame): Inherit from ThubanFrame so we can have a
1619            status bar and control buttons.
1620            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
1621            Explicitly set which items are selected in the operator choice and
1622            action choice so there is always a valid selection. Fixes RTbug #1941.
1623            Subscribe to grid cell selection events so we can update the
1624            status bar.
1625            (QueryTableFrame.UpdateStatusText): Update the status bar with
1626            how many rows are in the grid, how many columns, and how many
1627            rows are selected.
1628            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
1629            Call UpdateStatusText when cells are (de)selected.
1630            (QueryTableFrame.OnQuery): Use the string value in the value
1631            combo if either the selected item index is 0 or if the string
1632            cannot be found in the predefined list (this happens if the
1633            user changes the text). Fixes RTbug #1940.
1634            Only turn off the grid event listeners if there a query comes
1635            back with a none empty list of ids. in the case that the list
1636            is empty this causes a grid.ClearSelection() call to actually
1637            clear the grid selection which causes the selected items in
1638            the map to be deselected. Fixes RTbug #1939.
1639    
1640            * test/test_save.py (XMLWriterTest.Encode): Check return values.
1641            Fixes RTbug #1851.
1642    
1643    2003-06-13  Bernhard Herzog  <[email protected]>
1644    
1645            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
1646            self.selected_shape with the current selection to make sure the
1647            contents of the dialog are up to date when it's shown for the
1648            first time.
1649            The dialog used to work without this by luck. The recent fix to
1650            the connector module 'broke' a 'feature' the identify view was
1651            relying on, i.e that subscribing to a message in response to
1652            receiving a message of that type would mean that the new
1653            subscriber would also be called for the same message.
1654            
1655    2003-06-12  Jonathan Coles   <[email protected]>
1656    
1657            * extensions/thuban/gdalwarp.cpp: Removed debug printing as
1658            the image is rendered. Fixes RTbug #1937.
1659    
1660    2003-06-12  Jonathan Coles   <[email protected]>
1661    
1662            * Thuban/Lib/fileutil.py: As is done under Windows, create the
1663            user directory if it doesn't exist on a posix system.
1664            Fixes RTbug #1815.
1665    
1666            * Thuban/Model/resource.py (get_user_proj_files): Moved the
1667            called to get_application_dir here, so that the directory
1668            will only be called if this method is invoked.
1669    
1670            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
1671            the projfilepath if no projection is selected.
1672    
1673    2003-06-12  Jonathan Coles   <[email protected]>
1674    
1675            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
1676            the scalebar if the current map has no projection set.
1677    
1678            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
1679            projfilepath label to just the basename of the projection file
1680            rather than include the entire path.
1681    
1682            * Thuban/Model/resource.py: Fix missed proj functions that
1683            needed to be renamed.
1684    
1685    2003-06-12  Jonathan Coles   <[email protected]>
1686    
1687            * Thuban/Model/classification.py: Removed assert statements that
1688            tested if the variable was an instance of Color.
1689    
1690            * Thuban/Model/color.py (Color): Remove commented code that isn't
1691            used.
1692            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
1693            Fixes RTbug #1835.
1694            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
1695            Needed now that the class doesn't inherit from Color.
1696    
1697    2003-06-12  Jonathan Coles   <[email protected]>
1698    
1699            * test/test_save.py (XMLWriterTest.testEncode): Explicitly
1700            check unicode strings.
1701    
1702            * test/test_layer.py: Check for existence of gdal.
1703    
1704    2003-06-12  Jonathan Coles   <[email protected]>

1710            that was in save.py
1711    
1712    2003-06-12  Jonathan Coles   <[email protected]>
1713    
1714            This is largely a collection of bug fixes. We also handle the
1715            case where gdal is not on the system. The XMLReader and XMLWriter
1716            classes were moved into there own files to resolve some circular
1717            import references and because they shouldn't really be in the
1718            file that is dediciated to reading/writing session files since
1719            they are also used elsewhere.
1720    
1721            * Thuban/Model/classgen.py: Renamed functions to follow the
1722            function_names_with_underscores style. Fixes RTbug #1903.

1729            * Thuban/Model/load.py (XMLReader): Moved into seperate file
1730            xmlreader.py.
1731    
1732    2003-06-12  Jonathan Coles   <[email protected]>

1777            Addresses RTbug #1877.
1778    
1779            * test/test_classgen.py: Add tests for generate_singletons,
1780            generate_uniform_distribution, generate_quantiles. Fixes RTbug #1903.
1781            (test_calculate_quantiles): Fix some tests to catch the new
1782            ValueError that is raised.
1783

1825    
1826            * Thuban/Lib/connector.py (Connector.Issue): Iterate over a copy

1830            * test/test_connector.py
1831            (ConnectorTest.test_disconnect_in_receiver): New. Test whether

1842            LAYER_CHANGED will still be sent if the classification changes.
1843    
1844            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
1845            parameter so we can subscribe to some of its messages
1846            (Classifier.__init__): Subscribe to the map's MAP_LAYERS_REMOVED
1847            and the layer's LAYER_SHAPESTORE_REPLACED
1848            (Classifier.unsubscribe_messages): New. Unsubscribe from message
1849            subscribed to in __init__
1850            (Classifier.map_layers_removed)
1851            (Classifier.layer_shapestore_replaced): receivers for the messages

1884    
1885            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
1886            once on initialisation (Former implementation resulted in multiple

1889            if set, select the projection found under the specified name. This
1890            overwrites any other selection estimate.
1891            Removed projchoice filling from this method.
1892            (ProjFrame._OnSave, ProjFrame._OnAddToList):

1911    
1912            Do not cache the values returned by the tree widget's
1913            GetFirstChild and GetNextChild methods because it led to lots of

1915            reliable.
1916    
1917            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
1918            variable layer2id

1955    
1956    2003-06-02  Bernhard Herzog  <[email protected]>
1957    
1958            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource

1969            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
1970            variables to None that have direct or indirect references to

2009            of the ClassGenerator class. Put try/finally blocks around

2047            to be compiled as a standalone app. Now the code can only be
2048            called from Python which simplifies the parameter passing.
2049            (ProjectRasterFile): Handle Python arguments. Remove code that
2050            checks for a destination dataset. Add more clean up code.
2051

2273            anyway.
2274            
2275            * Thuban/Model/transientdb.py (TransientTableBase.Width):Use a

2376    
2377            * Thuban/UI/tableview.py (LayerTableFrame, QueryTableFrame): Split the
2378            class LayerTableFrame into two classes, LayerTableFrame and QueryTableFrame.

2381            to a layer.
2382    
2383            * Thuban/UI/mainwindow.py (MainWindow.TableShow): A very coarse
2384            implementation that still needs work.
2385

2387    
2388    2003-05-22  Frank Koormann  <[email protected]>

2420    
2421            * Thuban/UI/join.py (JoinDialog): Functional implementation of
2422            former framework. Renamed Table1/Table2 to LeftTable/RightTable
2423            in all occurences.
2424    
2425            * Thuban/Model/transientdb.py (TransientJoinedTable.__doc__):
2426            Typo fixed.
2427    
2428    2003-05-22  Bernhard Herzog  <[email protected]>
2429    
2430            Give the tables titles so that the GUI can display more meaningful
2431            names. For now the titles are fixed but depend on e.g. filenames
2432            or the titles of the joined tables.
2433    
2434            * Thuban/Model/transientdb.py (TransientTable.Title)
2435            (TransientJoinedTable.Title, AutoTransientTable.Title): New.

2444            methods
2445    
2446            * test/test_memory_table.py (TestMemoryTable.test_title): New.
2447            Test for the Title method
2448    
2449            * test/test_dbf_table.py (TestDBFTable.test_title): New. Test for
2450            the Title method
