12    
13            First step towards PostGIS integration. More abstraction by movin
14            more code from the layer to the shapestore. More methods of the
15            layer are now simply delegated to the equivalent method of the
16            shapestore. The SHAPETYPE_* constants are now in data not in
17            layer.
18    
19            * Thuban/Model/data.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
20            (SHAPETYPE_POINT, Shape): Move these constants and classes from
21            layer.py to data.py
22            (ShapefileStore.__init__): More Initialization for the new methods
23            and functionality.
24            (ShapefileStore.ShapeType, ShapefileStore.NumShapes)
25            (ShapefileStore.BoundingBox, ShapefileStore.ShapesInRegion)
26            (ShapefileStore.Shape): New methods that were formerly implemented
27            in the layer.
28            (DerivedShapeStore.Shape, DerivedShapeStore.ShapesInRegion)
29            (DerivedShapeStore.ShapeType, DerivedShapeStore.NumShapes)
30            (DerivedShapeStore.BoundingBox): New. DerivedShapeStore
31            equivalents of the new shape methods. These versions are simply
32            delegated to the original shapstore.
33    
34            * Thuban/Model/layer.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
35            (SHAPETYPE_POINT, Shape): Removed. They're now in data.py
36            (Layer.SetShapeStore): Removed the initializatin of instance
37            variables that were needed for the stuff that's now in
38            ShapefileStore
39            (Layer.BoundingBox, Layer.NumShapes, Layer.ShapeType)
40            (Layer.Shape, Layer.ShapesInRegion): Simply delegate to the
41            shapestore.
42    
43            * Thuban/UI/classifier.py, Thuban/UI/renderer.py,
44            Thuban/UI/viewport.py: Import the SHAPETYPE_* constants from data
45            instead of layer.
46    
47            * test/test_shapefilestore.py: New. Tests for ShapefileStore.
48    
49            * test/test_derivedshapestore.py: New. Tests for DerivedShapeStore.
50    
51            * test/test_layer.py: Import the SHAPETYPE_* constants from data
52            instead of layer.
53            (TestLayer.test_derived_store): Remove the test for the exception
54            when instantiating the DerivedShapeStore with an incompatible
55            table which is now in test_derivedshapestore.py. Add some more
56            tests of the layer methods to determine whether they work for a
57            DerivedShapeStore as well.
58    
59    2003-07-31  Jonathan Coles   <[email protected]>
60    
61            * Doc/manual/thuban-manual.xml: Fix the list of required packages
62            by just listing the name and where they can be found.
63    
64    2003-07-31  Frank Koormann   <[email protected]>
65    
66            * Doc/manual/thuban-manual.xml:
67            Changed the screenshot elements to figure.
68            Changed some variablelist elements to itemizedlist.
69            Added section on GDAL formats.
70    
71    2003-07-31  Jonathan Coles   <[email protected]>
72    
73            * Doc/manual/thuban-manual.xml: Added a few sentences about
74            the Fix Border Color option when generating classes.
75    
76    2003-07-30  Jonathan Coles   <[email protected]>
77    
78            * Thuban/Model/classgen.py: Add docstrings. Rename specific
79            Ramp instances to use lower_case_style.
80    
81            * Thuban/UI/classgen.py: Use renamed Ramp instances.
82            
83            * Thuban/UI/classifier.py: Add docstrings.
84    
85            * Thuban/UI/dock.py: Add docstrings.
86    
87            * test/test_classgen.py: Use renamed Ramp instances.
88    
89    2003-07-30  Bernhard Herzog  <[email protected]>
90    
91            * Thuban/Lib/connector.py (QueueingPublisher): Removed. This class
92            was never used in Thuban.
93    
94    2003-07-30  Bernhard Herzog  <[email protected]>
95    
96            * Thuban/UI/join.py (JoinDialog.__init__): Use the table's Title()
97            method directly instead of going through the transient_table
98            method. This faster because transient_table may force the copy of
99            a DBF file into the transient database and setting a table's title
100            doesnm't affect the title of the associated transient table, so
101            this fixes RT #2042
102    
103            * Thuban/UI/main.py (__version__): Don't import the already
104            removed show_exception_dialog.
105    
106    2003-07-29  Jonathan Coles   <[email protected]>
107    
108            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
109            Put back this method and remove the equivalent function since we
110            are setting the exception hook from within this class (OnInit).
111    
112    2003-07-29  Jonathan Coles   <[email protected]>
113    
114            * Doc/manual/images/5_2_custom_ramp.png,
115            Doc/manual/images/5_2_quantiles.png,
116            Doc/manual/images/5_2_uniform_dist.png,
117            Doc/manual/images/5_2_unique_values.png,
118            Doc/manual/images/8_int_error.png: New screen shots.
119    
120            * Doc/manual/thuban-manual.xml: Fixed typos and wording, clarified
121            some points, and added more screen shots.

125            * Thuban/Model/data.py: Remove the now unused import of warnings
126    
127    2003-07-29  Bernhard Herzog  <[email protected]>
128    
129            * Thuban/Model/data.py (SimpleStore): Removed. This class has been
130            deprecated since before the 0.8 release and isn't used in Thuban
131            itself anymore.
132    
133            * Thuban/Model/transientdb.py: Remove some unnecessary imports
134    
135    2003-07-29  Jonathan Coles   <[email protected]>
136    
137            * Thuban/UI/application.py (ThubanApplication.OnInit): set the
138            python exception hook here so that we are sure to catch any
139            Thuban exception that happen during initialization.
140    
141            * Thuban/UI/main.py (main): Don't set the exception hook here,
142            it will get set in ThubanApplication.OnInit.
143    
144    2003-07-29  Jonathan Coles   <[email protected]>
145                                                                                
146            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
147            Removed and called it show_exception_dialog() so that the exception
148            handler can be set before the class is created.
149                                                                                
150            * Thuban/UI/main.py (main): Install the exception handler before

207    2003-07-24  Bernhard Herzog  <[email protected]>
208    
209            * Thuban/Model/range.py, Thuban/version.py: Remove the #! line as
210            it annoys lintian which warns about these files not being
211            executable. The #1 isn't necessary here since if you absolutely
212            must execute them you can always say "python <filename>".
213    
214            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Remove
215            superfluous code to set brush and pen for point shapes

227            correctly.
228    
229    2003-07-22  Jonathan Coles   <[email protected]>
230    
231            * Doc/manual/thuban-manual.xml: Continue to write first revision
232            of the manual.
233    
234            * Thuban/UI/renderer.py (MapRenderer.render_map): Wrap method
235            with Begin/EndDrawing() calls to ensure we aren't doing to
236            many updates to the dc during rendering.
237            (ScreenRenderer.draw_shape_layer): self.draw_point_shape takes
238            a pen and brush argument so they need to be passed to the function.
239    
240            * Thuban/UI/viewport.py (ViewPort.calc_min_max_scales): New.
241            Calculates the minimum and maximum scale values. Factored out

243            way into a single point.
244            (ViewPort.set_view_transform): Call calc_min_max_scales().
245            (ViewPort.FitSelectedToWindow): Zoom to the maximum scale

276            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages):
277            Delegate MAP_REPLACED to the canvas too
278            (MainWindow.prepare_new_session): Removed. Thanks to the new
279            MAP_REPLACED message it's no longer needed
280            (MainWindow.OpenSession, MainWindow.NewSession):
281            prepare_new_session has been removed.
282    
283            * Thuban/UI/classifier.py (Classifier.__init__): Subscribe to
284            MAP_REPLACED so that we can close the dialog if a new map is set.

295    
296    2003-07-18  Bernhard Herzog  <[email protected]>
297    
298            * test/test_viewport.py (SimpleViewPortTest.test_default_size):
299            Move this test from ViewPortTest.setUp to this new separate test
300            case. setUp is not the place for the actual tests.
301            (ViewPortTest.test_inital_settings, ViewPortTest.setUp): Move some
302            more of the test from setUp to the new test test_inital_settings.

316    
317    2003-07-18  Bernhard Herzog  <[email protected]>
318    
319            * test/runtests.py: The test suite can now be run without an X
320            connection. To make sure this remains true, remove the DISPLAY
321            environment variable so that an error occurs if the wxGTK is
322            imported accidentally
323

342            renamed to output_transform
343    
344            * Thuban/UI/viewport.py (OutputTransform, output_transform):
345            Rename to output_transform
346    
347    2003-07-18  Bernhard Herzog  <[email protected]>
348    
349            * Thuban/Model/layer.py (Layer.__init__): Rename
350            classificationField to classificatin_column and init it here so

382            * test/test_layer.py (SetShapeStoreTests.setUp)
383            (SetShapeStoreTests.test_sanity): Update because of field->column
384            method name changes in the Layer class
385            (TestLayerModification.setUp): Subscribe to LAYER_CHANGED as well
386            (TestLayerModification.test_sanity)
387            (TestLayerModification.test_initial_settings): remove unsued code
388            and rename to test_sanity.
389            (TestLayerModification.test_set_classification): New test for
390            SetClassification and SetClassificationField.
391    
392    2003-07-18  Bernhard Herzog  <[email protected]>
393    
394            * test/test_classgen.py (TestFixedRamp.test): Extend test to check
395            the non-fixed values as well. The old test would have accepted a
396            fixed ramp that only returnes the fixed properties
397    
398    2003-07-17  Jonathan Coles   <[email protected]>
399    
400            * Doc/manual/mainwindow.png, Doc/manual/mainwindow.xcf: Screen
401            shots for the manual. The XCF file is the source image and
402            has additional layers to support changes.
403    
404            * Doc/manual/thuban-manual.xml: Wrote an initial Introduction.
405    
406            * Thuban/UI/classifier.py (Classifier.__BuildClassification):
407            Return both the new class and the field name.
408    
409            * Thuban/UI/mainwindow.py (MainWindow.ToggleLegend): Don't
410            fit the map to the window as this changes any zoom level that
411            the user may have set.
412    
413    2003-07-16  Jonathan Coles   <[email protected]>
414    
415            * Thuban/Model/classgen.py (generate_singletons,
416            generate_uniform_distribution, generate_quantiles): Remove
417            fixes parameter, but maintain the same functionality by having
418            the calling function pass a FixedRamp object for the ramp.
419            (FixedRamp): New. Adapts a ramp to have fixed property values.
420    
421            * Thuban/Model/classification.py: Use new CLASS_CHANGED message.
422            (Classification): Inherit from Publisher.

424            Classifications no longer need to have a parent layer.
425            (Classification.GetField, Classification.GetFieldType,
426            Classification.SetFieldInfo): Removed. The field name is stored
427            in the layer, and the type can be retreived by calling
428            Layer.GetFieldType().
429            (Classification._set_layer, Classification.GetLayer): Removed.
430            Classifications no longer have a parent layer.
431    
432            * Thuban/Model/layer.py (Layer.Destroy): Unsubscribe from the
433            classification.
434            (Layer.SetShapeStore): Reset the classification first while
435            we still have the old shape store to work with.
436            (Layer.GetClassificationField, Layer.SetClassificationField):
437            New. Method for getting/setting the field to classify on.
438            (Layer.SetClassification): Simplified now that the layer
439            simply has to hold a reference to the classification and not
440            tell the classification who owns it.
441            Fixes RTbug #2023.
442    
443            * Thuban/Model/load.py (SessionLoader.start_classification):
444            Set the field name on the layer, not the classification.
445    
446            * Thuban/Model/messages.py: Add CLASS_CHANGED for when a
447            classification is modified.
448    
449            * Thuban/Model/save.py (SessionSaver.write_classification):
450            Get the field name and type from the layer.
451    
452            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Renamed
453            parameter records to rows and add docstring. Fixes RTbug #1997.
454    
455            * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Use a fixed
456            ramp when we need to fix certain values of a ramp rather than
457            using the old fixes parameter. Fixes RTbug #2024.
458    
459            * Thuban/UI/classifier.py (ClassGrid.CreateTable): Add fieldType
460            parameter.
461            (ClassTable.Reset): Add fieldType parameter and use it, rather
462            than asking the classification.
463            (Classifier.__init__): Remember the original class's field
464            and ask the layer for the field type, rather than the classification.
465            (Classifier.__SetGridTable): Retrieve the field and field type
466            for the table because they are not in the classification.
467            (Classifier._OnTry, Classifier._OnRevert): Set the classification
468            field on the layer in addition to the classification itself.
469    
470            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Get the
471            classification field from layer.
472    
473            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Get the
474            classification field from layer. Split up tests and remove
475            *-imports. Fixes RTbug #1992.

477            * test/test_classgen.py (TestFixedRamp): Test for the FixedRamp class.
478    
479            * test/test_classification.py
480            (TestClassification.test_classification): Remove tests for methods
481            that no longer exist.
482    
483            * test/test_layer.py (SetShapeStoreTests.setUp): Classification
484            __init__ no longer has a field parameter, use SetClassificationField.
485            (SetShapeStoreTests.test_sanity): Use layer object to get class
486            field info.
487    
488            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Use
489            SetClassificationField on layer to set class field info.
490    
491            * test/test_viewport.py: Renamed from test/test_view.py.
492    
493    2003-07-16  Jan-Oliver Wagner <[email protected]>
494    
495            * Doc/manual/thuban-manual.xml: Added authors and an initial
496            coarse structure.
497    
498    2003-07-15  Bernhard Herzog  <[email protected]>
499    
500            * test/support.py (FloatComparisonMixin): This is a mix-in class
501            and therefore should not be derived from any other class.
502    
503            * test/test_range.py (RangeTest): FloatComparisonMixin is a
504            mix-in, so derive from TestCase as well.
505    
506    2003-07-15  Bernhard Herzog  <[email protected]>
507    
508            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Rework the
509            draw_func handling a bit to remove one layer of indirection. This
510            makes the renderer about 10% faster in the non-classifying case
511            and the code a bit cleaner
512            (MapRenderer.draw_point_shape): Add the pen and brush parameters
513            and set them in the dc. Now the draw_point_shape method and
514            wxproj's draw_polygon_shape function have basically the same
515            signature so that both can be directly used as draw_func
516    
517    2003-07-15  Bernhard Herzog  <[email protected]>
518    
519            * Thuban/Model/save.py (SessionSaver.write_classification): Encode
520            string values (in addition to the labels) as UTF 8
521    
522            * Thuban/Model/load.py (SessionLoader.start_clpoint): Decode the
523            values if the field type is string
524    
525            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Test
526            saving a session with non-ascii string classification values.
527    
528            * test/test_load.py (TestClassification.file_contents)
529            (TestClassification.test): Check for non-ascii values in string
530            classifications
531    
532    2003-07-14  Jonathan Coles   <[email protected]>
533    
534            * test/test_view.py: New. Tests for ViewPort.
535    
536    2003-07-14  Frank Koormann   <[email protected]>
537    
538            * Thuban/Model/load.py (SessionLoader.start_map): Encode map
539            title to latin1.  Fixes https://intevation.de/rt/webrt?serial_num=2013

545    2003-07-10  Jonathan Coles   <[email protected]>
546    
547            * Thuban/UI/viewport.py (Tool.MouseUp): Should have called
548            drag_stop, not drag_move when the mouse is released.
549    
550    2003-07-10  Jonathan Coles   <[email protected]>
551    
552            The most important part of this is the seperation of view.py into
553            two pieces. viewport.py now has a class called ViewPort which
554            contains all the non-wx parts of view.py and can therefore be
555            tested. view.py contains only the wx-specific parts and is fairly
556            simple.
557    
558            * Thuban/UI/view.py: Stripped out all non-wx functionality. Fixes
559            RTTbug #1992.
560            * Thuban/UI/viewport.py: New. Contains non-wx view functionality.
561            RTTbug #1992.

563            * Thuban/Model/classgen.py (generate_singletons,
564            generate_uniform_distribution, generate_quantiles):
565            Added 'fixes' parameter so that property attributes can
566            be held constant over the generated classification groups.
567            (CustomRamp.GetProperties): Remove unused variables.
568    
569            * Thuban/Model/map.py (Map.SetProjection): Send the old
570            projection as an argument to listeners of the MAP_PROJECTION_CHANGED
571            event.
572    
573            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Added 'records'
574            parameter which is a list of records that restricts which
575            records are saved. Fixes RTbug #1997.
576    
577            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
578            Port exception dialog from GREAT-ER. Fixes RTbug #1993.
579    
580            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Add controls
581            to allow the user to fix line color/width on generated groups.
582            (ClassGenDialog.OnOK): Use new 'fixes' parameter of the generate_*
583            functions to optionally fix group properties.
584    
585            * Thuban/UI/main.py (main): Set exception hook to the
586            ShowExceptionDialog. Fixes RTbug #1993.

592            Export Selection button and move the export buttons underneath
593            the table.
594            (QueryTableFrame.UpdateStatusText): Added event argument so
595            that it can respond to grid selection events. The status text
596            is now updated even when the table is not associated with a
597            layer as was previously assumed.
598            (QueryTableFrame.OnGridSelectRange, OnGridSelectCell): Removed.
599            UpdateStatusText responds to these events.
600            (QueryTableFrame.OnSaveAs): Renamed to doExport.
601            (QueryTableFrame.doExport): Helper function that saves the
602            entire table, or selected rows, to a file.
603            (QueryTableFrame.OnExport, QueryTableFrame.OnExportSel): New.
604            Respond to export button events and call doExport.
605    
606            * extensions/thuban/gdalwarp.cpp (ProjectRasterFile): Make sure
607            the function doesn't return NULL without first setting a Python
608            Error.

610            * test/runtests.py (main): Only print "Unknown option" for
611            unsupported options.
612    
613            * test/support.py (FloatComparisonMixin.assertFloatEqual): Take
614            optional epsilon argument to specify floating point accuracy.
615            (FloatComparisonMixin.assertFloatSeqEqual): Call assertFloatEqual
616            for each item test.
617    
618            * test/test_csv_table.py (TestCSVTable.test_table_to_cvs): Add
619            tests for saving selected records.
620    
621            * test/test_dbf_table.py (TestTableToDBF.test_table_to_dbf): Add
622            tests for saving selected records.
623    
624            * test/test_map.py (TestMapWithContents.test_set_projection):
625            MAP_PROJECTION_CHANGED events send the old projection.
626    
627            * test/test_session.py
628            (TestSessionWithContent.test_forward_map_projection):
629            MAP_PROJECTION_CHANGED events send the old projection.
630    
631            * test/test_table.py (TableTest): Update tests to use non-deprecated
632            functions.
633    
634    2003-07-08  Bernhard Herzog  <[email protected]>
635    
636            * Thuban/Model/transientdb.py (TransientTableBase.Width): The type
637            constants in the column objects are the standard ones defined in
638            the table module.
639    
640            * test/test_transientdb.py
641            (TestTransientTable.test_transienttable_to_dbf): New. Test whether
642            exporting transient tables as DBF works. This should catch the bug
643            just fixed in TransientTableBase.Width.
644    
645    2003-07-08  Bernhard Herzog  <[email protected]>
646    
647            * Thuban/Model/classgen.py (CustomRamp.GetProperties): Compute the
648            interpolated colors correctly.
649    
650            * test/test_classgen.py (TestCustomRamp.test_color_interpolation):
651            New. Test case for the fix in classgen.py
652    
653    2003-07-08  Bernhard Herzog  <[email protected]>
654    
655            * test/runtests.py (main): Make the default output less verbose
656            and add a verbosity option (-v) to get the old output
657

659    
660            * Resources/XML/thuban-0.9.dtd: New. This will become the DTD for

721    2003-07-03  Bernhard Herzog  <[email protected]>
722    
723            * Thuban/Model/transientdb.py (TransientJoinedTable.__init__):
724            Update doc-string
725            (TransientJoinedTable.create): Do not modify the column objects of
726            the input tables in place and copy all columns of the input tables

758            to never to reach one.
759    
760    2003-07-02  Jonathan Coles   <[email protected]>
761    
762            Changed the singature of ClassGroupRange.__init__ and
763            ClassGroupRange.SetRange() so that the min/max values are
764            passed as a tuple. This makes a better calling scheme for
765            when a Range object is passed instead.
766    
767            * Thuban/Model/classgen.py: Fixed parameters to
768            ClassGroupRange constructor.

773            (ClassGroupRange.SetRange): Consolidate the min/max parameters
774            into a single _range which can either be a tuple or a Range object.
775    
776            * Thuban/Model/load.py (SessionLoader.start_clrange): Fix
777            call to ClassGroupRange constructor to use a tuple.
778    
779            * Thuban/Model/layer.py (Layer.SetClassification): Switch
780            the classification instance variable to the new class
781            before calling _set_layer otherwise subscribers to a
782            LAYER_CHANGED event will not see any difference.
783    
784            * test/test_classification.py: Fix tests of ClassGroupRange
785            so that they use the new signature.
786    
787            * test/test_load.py: Fix use of ClassGroupRange so that it
788            uses the new signature.
789    
790            * test/test_load_0_2.py: Fix use of ClassGroupRange so that it
791            uses the new signature.
792    
793            * test/test_save.py: Fix use of ClassGroupRange so that it
794            uses the new signature.

797    2003-07-01  Jonathan Coles   <[email protected]>
798    
799            * Thuban/Model/classgen.py: Fixes RTbug #1972, 1971.
800            Import used objects/class from color.
801            (generate_singletons): We don't
802            need the numGroups parameter anymore because we are using
803            the new ramps with GetProperties().
804            (generate_uniform_distribution): Use new ramp method
805            GetProperties().
806            (generate_quantiles, GenQuantiles0): Use new ramp method
807            GetProperties().
808            (CustomRamp.SetNumGroups): Removed. The ramps now map
809            a value from 0 to 1 to class properties so the number
810            of groups is not needed ahead of time.
811            (CustomRamp.next): Removed. CustomRamp does not support
812            interation anymore.
813            (CustomRamp.GetProperties): Returns a ClassGroupProperties
814            object based on the index value from 0 to 1 that is
815            passed to it.
816            (GreyRamp, RedRamp, GreenRamp, BlueRamp, GreenToRedRamp):
817            Made into instances of Monochromatic class instread of
818            deriving from it.
819            (HotToCold.SetNumGroups): Removed. See CustomRamp.
820            (HotToCold.next): Removed. See CustomRamp.
821    
822            * Thuban/Model/classification.py: Fixes RTbug #1973, 1971.
823            (Classification.SetField, Classification.SetFieldType):
824            Replaced with SetFieldInfo.
825            (Classification.SetFieldInfo): New. Does a better job of
826            what SetField and SetFieldType used to do by combining
827            their function since they should really always be done
828            at the same time.
829            (Classification.SetLayer): Renamed to _set_layer.
830            (Classification._set_layer): Should only be called from
831            Layer's SetClassification. This does not cause a recursive
832            call as SetLayer did because we know that Layer knows about
833            the classification.
834    
835            * Thuban/Model/color.py: Fixes RTbug #1971.
836            (_Transparent): Renamed from Transparent so it doesn't
837            conflict with the module variable.
838            (Transparent, Black): Renamed from Color.Transparent,
839            Color.Black so they are not class variables.
840    
841            * Thuban/Model/layer.py: Fixes RTbug #1971, 1973.
842            (Layer.Destroy): We don't need to call SetClassification
843            anymore to clear out the back reference in the classifcation
844            to the layer. It's better to set it to None using _set_layer,
845            and we won't be creating another clas object too.
846            (Layer.SetClassification): Classification._set_layer is not
847            recursive so remove all the locking variables. Also clean
848            up the code so that it remains unchanged if something fails.
849    
850            * Thuban/Model/load.py: Fixes RTbug #1971.
851            (SessionLoader.start_classification): Call
852            Classification.SetFieldInfo().
853    
854            * Thuban/Model/save.py: Removed import of Color which wasn't
855            being used.
856    
857            * Thuban/UI/classgen.py: Fixes RTbug #1972.
858            (ClassGenDialog.__init__): Color ramps are now instances
859            already so we don't need to create any new objects.
860            (ClassGenDialog.OnOK): Check for numGroups is no longer
861            necessary because we never use it.
862    
863            * Thuban/UI/classifier.py: Fixes RTbug #1971.
864            (Classifier.__BuildClassification, Classifier.__SetGridTable):
865            Call Classification.SetFieldInfo() instead of SetFieldType.
866    
867            * Thuban/UI/renderer.py: Fixes RTbug #1971.
868    
869            * Thuban/UI/view.py: Fixes RTbug #1974, 1971.
870            (MapCanvas.__init__): Subscribe to the idle time event. Set
871            background color to white.
872            (MapCanvas.OnPaint): Set a flag indicating that we should
873            render the map during idle time. If we already have a bitmap
874            just draw it now.
875            (MapCanvas.OnIdle): New. Render the map only during idle time.
876            This also fixes a problem with the busy cursor under gtk.
877    
878            * test/test_classgen.py (ClassGenTest.test_generate_singletons):
879            Fix calls to generate_singletons because the signature changed.
880    
881            * test/test_classification.py: Fix color references and
882            change calls to Classification.[SetField|SetFieldType] to
883            SetFieldInfo.
884    
885            * test/test_load.py: Fix color references.
886    
887            * test/test_load_0_2.py: Fix color references.
888    
889            * test/test_save.py (SaveSessionTest.testClassifiedLayer):
890            Change calls to Classification.[SetField|SetFieldType] to
891            SetFieldInfo.
892    
893    2003-07-01  Frank Koormann   <[email protected]>
894    
895            MERGE from the greater-ms3 branch.
896    
897            * test/test_transientdb.py
898            (TestTransientTable.test_transient_joined_table_with_equal_column_names):
899            New. Test join of two tables with partly equal column names.
900    
901            * Thuban/Model/transientdb.py (TransientJoinedTable.create):
902            If duplicates in left and right tables column names are found,
903            append '_' (underscores) to the name until it is unique.
904            Create always new internal names for the resulting table and reference
905            columns in the join statement with <table>.<column>
906    
907    2003-07-01  Bernhard Herzog  <[email protected]>
908    
909            * test/test_transientdb.py
910            (TestTransientTable.test_transient_joined_table_same_column_name):
911            New. Test whether joining on columns with the same names in both
912            tables works.
913            
914            * Thuban/Model/transientdb.py (TransientJoinedTable.create): Make
915            sure to use the right internal names even when joining on field
916            with the same names in both tables. Also, detect duplicate names
917            in the joined table correctly.
918    
919    2003-07-01  Frank Koormann   <[email protected]>
920    
921            * Thuban/UI/renderer.py (ExportRenderer.render_legend):
922            Reverse List of layers to render in same order as in desktop legend.
923    
924    2003-06-30  Jonathan Coles   <[email protected]>
925    
926            * Thuban/version.py (make_tuple): Takes a version string
927            and splits it into a tuple of at most three integers.
928            Used make_tuple() to make tuple versions of the version
929            numbers.
930    
931            * Thuban/UI/about.py: Add Thuban email addresses.
932    
933    2003-06-30  Jonathan Coles   <[email protected]>
934    
935            * Thuban/version.py: SQLite/PySQLite version dependencies
936            were too high.
937    
938    2003-06-30  Jonathan Coles   <[email protected]>
939    
940            * Thuban/version.py: Update version to 0.8.1
941            
942            * MANIFEST.in: Added Projections so that default.proj is
943            included.
944    
945    2003-06-26  Jonathan Coles   <[email protected]>
946    
947            New About box with lots more information including library
948            versions and credits. More/better version checking before
949            Thuban starts.
950    
951            * Thuban/UI/about.py: New. New About box that displays
952            library version information and credits.
953    
954            * Thuban/version.py: Added new 'versions' dictionary which
955            contains the verions of various libraries which are checked
956            when the module loads.
957            (verify_versions): Check all version numbers and returns
958            a list of errors.
959    
960            * Thuban/UI/classifier.py (Classifier.__EnableButtons):
961            Reset the status of the buttons as the situation warrants,
962            but in a better more reliable way by not relying on the
963            current status to determine what needs to change.
964    
965            * Thuban/UI/main.py (wxCHECK_VERSION): Removed. Not needed.
966            (verify_versions): Remove most of the code since it is
967            now in Thuban.version.verify_versions.o
968    
969            * Thuban/UI/mainwindow.py (MainWindow.About): Call new
970            About box in Thuban.UI.about.
971

978            was compiled with.
979            (get_gtk_version): Return th version of GTK that the file
980            was compiled with.
981    
982    2003-06-25  Jonathan Coles   <[email protected]>
983    
984            * Thuban/UI/classifier.py (Classifier.EditSymbol): The parent
985            of the SelectPropertiesDialog should be self so the window
986            appears on top.
987            (ClassGroupPropertiesCtrl.DoEdit): The parent
988            of the SelectPropertiesDialog should be self so the window
989            appears on top.
990    
991            * Thuban/UI/resource.py: Cleaned up how we determine file
992            extensions.
993            (GetImageResource): Return an wxImage from our Resources.
994    
995    2003-06-24  Jonathan Coles   <[email protected]>
996    
997            * Thuban/UI/renderer.py (ExportRenderer.render_legend):
998            Check that a layer has a classification before trying
999            to get it. Raster layers don't have classifications.
1000    
1001    2003-06-23  Jonathan Coles   <[email protected]>
1002            
1003            * setup.py: Add Resources/XML to resource list.
1004        
1005    2003-06-23  Jonathan Coles   <[email protected]>

1007            * setup.cfg: Fix copyright dates
1008        
1009    2003-06-23  Jonathan Coles   <[email protected]>
1010    
1011            * MANIFEST.in: Update with Resources/XML
1012    
1013            * setup.py: Don't include Locale resources yet as we don't
1014            have any and it causes problems building the distribution
1015            for Windows. Update version to 0.8.0.
1016    
1017            * Doc/thuban.dtd: Removed since it is now in Resources/XML.
1018    
1019            * Thuban/UI/mainwindow.py: Add blank line at the end because
1020            file was not being read correctly building the Windows
1021            distribution.
1022    
1023    2003-06-23  Jonathan Coles   <[email protected]>
1024    
1025            * Thuban/UI/mainwindow.py (MainWindow.About): Fix text.
1026    
1027            * Thuban/version.py: Temporarily update longversion for
1028            the 0.8 release so that it doesn't have the cvs revision.
1029    
1030    2003-06-23  Jonathan Coles   <[email protected]>
1031    
1032            * Thuban/UI/common.py (ThubanBeginBusyCursor): Call wxSafeYield
1033            to make sure that we don't create reentrant possibilities with
1034            wxYield.
1035    
1036            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxBeginBusyCursor()
1037            directly to avoid the wxSafeYield() call which generates an
1038            OnPaint event causing infinite recursion. Don't try to catch
1039            exception anymore. This was for before there were limits on map
1040            scaling.
1041    
1042    2003-06-23  Bernhard Herzog  <[email protected]>
1043    
1044            Bug fix for RT #1961:
1045    
1046            * Thuban/Model/load.py (SessionLoader.start_derivedshapesource):
1047            Register DerivedShapestores with the session
1048    
1049            * Thuban/Model/session.py (Session.Tables): Make sure each table
1050            is only listed once.
1051    
1052            * test/test_load.py (TestJoinedTable.test): Add check_format call.
1053            Update file contents to match the one written out.
1054    
1055    2003-06-20  Bernhard Herzog  <[email protected]>
1056    
1057            * test/xmlsupport.py (SaxEventLister.startElementNS)
1058            (SaxEventLister.endElementNS): Do not include the qname. Python
1059            2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
1060            is (presumably incorrectly) None, whereas it's a string with the
1061            element name in the later versions.
1062    
1063            * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
1064            (TestEventList.test_even_list_namespace): Update tests to reflect
1065            the new behaviour
1066            (TestEventList.test_even_list_id_normalization): Fix doc-string
1067    
1068    2003-06-20  Jonathan Coles   <[email protected]>
1069    
1070            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
1071            by deriving classes to determine if that layer supports shapes.
1072            (Layer): Override HasShapes and return true.
1073    
1074            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
1075            instead of a direct call to wx[Begin|End]CusyCursor().
1076            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
1077            table data.
1078    
1079            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
1080            New. Wrappers around the wxWindows functions that allow us to
1081            make additional calls such as wxYield which gives the native
1082            system a chance to update the cursor correctly.
1083    
1084            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
1085            instead of a direct call to wx[Begin|End]CusyCursor().
1086    
1087            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
1088            instead of a direct call to wx[Begin|End]CusyCursor().
1089            (MapCanvas.find_shape_at): Check if the current search layer
1090            support shapes, otherwise go on to the next layer.
1091    
1092            * test/test_layer.py: Add tests in each type of layer for
1093            HasClassification() and HasShapes()
1094    
1095    2003-06-20  Jonathan Coles   <[email protected]>
1096    
1097            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
1098            turning on the busy cursor to allow the system to change the
1099            cursor before we begin painting. This fixes a problem that
1100            was occuring only under GTK. Fixes RTbug #1840.
1101    
1102    2003-06-20  Bernhard Herzog  <[email protected]>
1103    
1104            * Resources/XML/thuban-0.8.dtd: New DTD for the new file format
1105            version.
1106    
1107            * Thuban/Model/save.py (sort_data_stores): New. Make topological
1108            sort of the data sources so they can be written with sources that
1109            data sources that depend on other data sources come after the
1110            sources they depend on.
1111            (SessionSaver.__init__): Add idmap instance variable to map from
1112            objects to the ids used in the file.
1113            (SessionSaver.get_id, SessionSaver.define_id)
1114            (SessionSaver.has_id): New. Methods to manage the idmap
1115            (SessionSaver.write): Use thuban-0.8.dtd
1116            (SessionSaver.write_session): Add a namespace on the session and
1117            write out the data sources before the maps.
1118            (SessionSaver.write_data_containers): New. Write the data
1119            containers.
1120            (SessionSaver.write_layer): Layer elements now refer to a
1121            shapestore and don't contain filenames anymore.
1122    
1123            * Thuban/Model/load.py (LoadError): Exception class to raise when
1124            errors in the files are discovered
1125            (SessionLoader.__init__): Define dispatchers for elements with a
1126            thuban-0.8 namespace too.
1127            (SessionLoader.check_attrs): New helper method to check and
1128            convert attributes
1129            (AttrDesc): New. Helper class for SessionLoader.check_attrs
1130            (SessionLoader.start_fileshapesource)
1131            (SessionLoader.start_derivedshapesource)
1132            (SessionLoader.start_filetable, SessionLoader.start_jointable):
1133            Handlers for the new elements in the new fileformat
1134            (SessionLoader.start_layer): Handle the shapestore attribute in
1135            addition to filename.
1136            (SessionLoader.start_table, SessionLoader.end_table): Removed.
1137            They were never used in the old formats and aren't needed for the
1138            new.
1139    
1140            * Thuban/Model/session.py (Session.DataContainers): New method to
1141            return all "data containers", i.e. shapestores and tables
1142    
1143            * test/xmlsupport.py (SaxEventLister.__init__)
1144            (SaxEventLister.startElementNS, sax_eventlist): Add support to
1145            normalize IDs.
1146    
1147            * test/test_xmlsupport.py
1148            (TestEventList.test_even_list_id_normalization): New test case for
1149            id normalization
1150    
1151            * test/test_load.py (LoadSessionTest.check_format): Use ID
1152            normalization
1153            (LoadSessionTest.thubanids, LoadSessionTest.thubanidrefs): New
1154            class atrributes used for ID normalization

1157            file format
1158            (TestJoinedTable): New test for loading sessions with joined
1159            tables.
1160            (TestLoadError): New. Test whether missing required attributes
1161            cause a LoadError.
1162    
1163            * test/test_save.py (SaveSessionTest.thubanids)
1164            (SaveSessionTest.thubanidrefs): New class attributes for ID
1165            normalization in .thuban files.

1169            (SaveSessionTest.testRasterLayer)
1170            (SaveSessionTest.testClassifiedLayer): Adapt to new file format.
1171            (SaveSessionTest.testLayerProjection): The filename used was the
1172            same as for testSingleLayer. Use a different one.
1173            (SaveSessionTest.test_dbf_table)
1174            (SaveSessionTest.test_joined_table): New test cases for saving the
1175            new data sources structures.
1176            (TestStoreSort, MockDataStore): Classes to test the sorting of the
1177            data stores for writing.
1178    
1179            * test/runtests.py: Add CVS keywords
1180    
1181    2003-06-20  Jonathan Coles   <[email protected]>
1182    
1183            * test/test_session.py
1184            (UnreferencedTablesTests.test_unreferenced_tables_with_joins):
1185            Use the cultural_landmark-point.dbf file for the store so that
1186            the table rows and shape count match.
1187    
1188    2003-06-20  Jonathan Coles   <[email protected]>
1189    
1190            * Thuban/Model/data.py (DerivedShapeStore.__init__): Raise
1191            an exception if the number of shapes is different from the
1192            number of rows in the table. Address RTbug #1933.
1193    
1194            * test/test_layer.py (TestLayer.test_derived_store): Add
1195            a test for the new exception in DerivedShapeStore.__init__.
1196    
1197            * test/support.py (FloatTestCase): Removed since there is
1198            already FloatComparisonMixin. Fixes RTbug #1954.
1199            (FloatComparisonMixin.assertFloatEqual): Include test for
1200            infinity that was part of FloatTestCase.
1201    
1202            * test/test_range.py (RangeTest): Inherit from
1203            support.FloatComparisonMixin now that we don't have
1204            support.FloatTestCase.
1205    
1206    2003-06-20  Bernhard Herzog  <[email protected]>
1207    
1208            * test/test_save.py (SaxEventLister, sax_eventlist): Removed. Use
1209            the implementation in xmlsupport instead.
1210            (SaveSessionTest.compare_xml): sax_eventlist is now in xmlsupport
1211    
1212            * test/test_proj.py: Import sax_eventlist from xmlsupport instead
1213            of test_save
1214    
1215    2003-06-20  Bernhard Herzog  <[email protected]>
1216    
1217            * test/test_load.py (LoadSessionTest.check_format): New helper
1218            method to make sure the test files we load might have been written
1219            by the current thuban version.
1220            (ClassificationTest.TestLayers, TestSingleLayer.test)
1221            (TestLayerVisibility.test, TestClassification.test)
1222            (TestLabels.test, TestLayerProjection.test, TestRasterLayer.test):
1223            Add check_format() calls and fix the thuban data to match the data
1224            that would be written by saving the session loaded from it.
1225    
1226            * test/xmlsupport.py (SaxEventLister, sax_eventlist): Copies of
1227            the same class and function in test_save.
1228    
1229            * test/test_xmlsupport.py (TestEventList): New. test cases for
1230            sax_eventlist
1231    
1232    2003-06-20  Bernhard Herzog  <[email protected]>
1233    
1234            * Resources/XML/thuban.dtd: Add comment about which versions of
1235            Thuban are covered by this DTD
1236            (map): Fix content model for layers and raster layers. There can
1237            be any number or layers and raster layers in any order.
1238    
1239    2003-06-20  Jonathan Coles   <[email protected]>
1240    
1241            This is mainly about fixing RTbug #1949.
1242    
1243            * Thuban/Model/classification.py: Remove "from __future__"
1244            import statement since python 2.2 is the earliest supported
1245            version.
1246    
1247            * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
1248            Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES
1249            depending on the units this projection *forwards* into.
1250    
1251            * Thuban/Model/save.py (SessionSaver.write_classification):
1252            Remove unnecessary use of lambdas and nested functions.
1253    
1254            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Do scale
1255            adjustment here if the map projection uses degrees.
1256    
1257            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
1258            scale adjust code since it is now done before calling
1259            this method. Don't do anything if the map projection
1260            is None.
1261    
1262    2003-06-19  Bernhard Herzog  <[email protected]>
1263    
1264            Move version specific load tests to their own file.
1265    
1266            * test/test_load.py: Expand the doc-string to explain a bit how to
1267            handle file format changes.
1268            (TestClassification.test): Update the docstring as this test is
1269            not about Thuban 0.2 anymore.
1270    
1271            * test/test_load_0_2.py: New file with the load tests for thuban
1272            files created with Thuban 0.2 and earlier.
1273    
1274    2003-06-19  Bernhard Herzog  <[email protected]>
1275    
1276            Add XML validation to some of the tests. Validation will only be
1277            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
1278            To make the DTD available to the test cases it's moved into
1279            Resources/XML
1280    
1281            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
1282            for versions up to and including 0.2. Two slight changes: added an
1283            encoding specification and fixed the comment which refered to
1284            GRASS, not Thuban
1285    
1286            * test/xmlsupport.py: New support module for tests involving XML.
1287            Currently there's a mix-in class for XML validation.
1288    
1289            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
1290    
1291            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
1292            so that we can validate the
1293            (SaveSessionTest.testEmptySession)
1294            (SaveSessionTest.testSingleLayer)
1295            (SaveSessionTest.testSingleLayer)
1296            (SaveSessionTest.testLayerProjection)
1297            (SaveSessionTest.testRasterLayer)
1298            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
1299    
1300            * test/runtests.py (main): Call print_additional_summary instead
1301            of print_garbage_information
1302    
1303            * test/support.py (resource_dir): New function to return the
1304            "Resource" subdirectory
1305            (print_additional_summary): New function to combine several
1306            summary functions
1307            (run_tests): Use print_additional_summary instead of calling
1308            print_garbage_information directly
1309    
1310    2003-06-19  Bernhard Herzog  <[email protected]>
1311    
1312            * Doc/thuban.dtd (classification): Correct the content model of
1313            the classification element.
1314            (projection): Add the "name" attribute
1315    
1316    2003-06-19  Frank Koormann   <[email protected]>
1317    
1318            MERGE from the greater-ms3 branch.
1319    
1320            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
1321            scale if projection is latlong to get better estimate.
1322    
1323            Fix problem of hidden properties dialog under windows after double
1324            click on layer tree:
1325            The tree control always gets an Expanded / Collapsed event after
1326            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
1327            raises the already displayed window.
1328    
1329            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
1330            raiseProperties initialized to prevent endless loops
1331            (LegendTree._OnItemActivated): Depending on self.raiseProperties
1332            simply raise the properties or open the dialog and issue a second
1333            event.
1334    
1335    2003-06-18  Jonathan Coles   <[email protected]>
1336    
1337            * setup.py: Fix a few problems that occured under Windows.
1338    
1339    2003-06-18  Jonathan Coles   <[email protected]>
1340    
1341            When Thuban loaded the map was redrawn twice because the
1342            legend was being opened after the mainwindow was created
1343            and not during its creation. This meant the map was drawn
1344            initially and then had to be redrawn when the legend
1345            caused the display to change. Now the legend is opened
1346            in the mainwindow constructor which resolves this issue.
1347    
1348            Also, although we were checking for the existence of
1349            gdal and gdalwarp modules, the gdalwarp extension was
1350            still being compiled (which may fail if the system doesn't
1351            have gdal installed). the build_ext command to setup.py
1352            now accepts the flags --with-gdal and --without-gdal.
1353            If --without-gdal is specified setup.py will try to
1354            use the gdal parameters specified by gdal-config. Under
1355            windows, those parameters have to be set in setup.py
1356            as with proj4 an wxWindows.
1357    
1358            * setup.py: Use a list instead of seperate variables for
1359            extension parameters so we can create a generic function
1360            that runs an appropriate *-config script.
1361            (run_cs_script): Renamed from run_wx_script and modified
1362            to accept a second argument which is a list of lists to
1363            be filled in by the values returned from running the command.
1364            (thuban_build_ext): New. Extends the build_ext command and
1365            provides the options --with-gdal/--without-gdal which then
1366            optionally includes the gdalwarp extension.
1367    
1368            * Thuban/Model/resource.py: First check if we can import
1369            the gdalwarp Thuban extension before checking for gdal.
1370            Also added some comments.
1371            
1372            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
1373            the map is None which may be the case if none has been loaded
1374            yet.
1375    
1376            * Thuban/UI/main.py (main): Remove call to ShowLegend.
1377    
1378            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
1379    
1380            * Thuban/UI/renderer.py: Check for gdal support before importing
1381            gdalwarp.
1382            (MapRenderer.render_map): Only try to optimize if we have gdal
1383            support otherwise nothing will get drawn.
1384    
1385            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
1386            during startup before a map has been created. Check if map is None
1387            before using it and do nothing if it is.
1388    
1389    2003-06-17  Jonathan Coles   <[email protected]>
1390    
1391            Fix the problem with raster layers under Windows that caused
1392            Thuban to crash. The view should respond to layer projection
1393            changed events to update the display. Changes to a projection
1394            should not cause the map to be set to full extent.
1395            
1396            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
1397            current_map_proj to remember the current map projection so that
1398            when the projection changes we know what the previous projection
1399            was.
1400            (MapCanvas.SetMap): Unsubscribe and subscribe to
1401            LAYER_PROJECTION_CHANGED events.
1402            (MapCanvas.projection_changed): Split into two methods that respond
1403            to map and layer projection changes.
1404            (MapCanvas.map_projection_changed): New. Takes the current view and
1405            projects it using the new projection. This does not cause the
1406            map to be redrawn at full extent.
1407            (MapCanvas.layer_projection_changed): New. Cause a redraw which
1408            will draw each layer in its new projection.
1409            
1410            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
1411            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
1412            under Windows.
1413            
1414            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
1415            to twice sizeof(void*) because there are two digits for each
1416            hex byte.
1417    
1418    2003-06-16  Bernhard Herzog  <[email protected]>
1419    
1420            Update to the layer interface: Direct access to the table,
1421            shapetable, shapefile and filename attributes is now actively
1422            deprecated by issuing deprecation warnings for all places where
1423            this happens.
1424    
1425            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
1426            to the instance variables table, shapetable, shapefile and
1427            filename via __getattr__ so that we can issue a deprecation
1428            warning.
1429            (Layer.SetShapeStore): Don't set the deprecated instance variables
1430            any more
1431            (Layer.SetShapeStore): Don't use deprecated layer instance
1432            variables
1433            (Layer.Destroy): No need to explicitly remove the instance
1434            variables any more
1435            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
1436            instance variables
1437    
1438            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
1439            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
1440            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
1441            use deprecated layer instance variables
1442    
1443            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
1444            deprecated layer instance variables
1445    
1446            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
1447            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
1448            instance variables
1449    
1450            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
1451            deprecated layer instance variables
1452    
1453            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
1454            deprecated layer instance variables
1455    
1456            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
1457            deprecated layer instance variables
1458    
1459            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
1460            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
1461            variables
1462    
1463            * test/runtests.py (main): Turn Thuban's deprecation warnings into
1464            errors so that they're cought by the tests
1465    
1466            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
1467            layer instance variables
1468    
1469    2003-06-16  Jonathan Coles   <[email protected]>
1470    
1471            Fix a problem under Windows whereby if the user double-clicks on a
1472            layer in the legend that tree item will expand or collapse as well
1473            as open the layer properties dialog. The state of the tree item
1474            should not be affected.
1475    
1476            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
1477            preventExpandCollapse and subscribe to expanding and collapsing
1478            events.
1479            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
1480            collapsing events and will veto the event if it has been triggered
1481            by the user double clicking on a layer.
1482            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
1483            that an expanding/collapsing event should be vetoed.
1484    
1485    2003-06-13  Bernhard Herzog  <[email protected]>
1486    
1487            * Thuban/UI/classifier.py (Classifier.OnClose)
1488            (Classifier.map_layers_removed)
1489            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
1490            in OnClose and not in map_layers_removed or
1491            layer_shapestore_replaced to make sure it always happens when the
1492            dialog is closed
1493    
1494    2003-06-13  Jonathan Coles   <[email protected]>
1495    
1496            This puts back a fix for Windows where a panel is needed so that
1497            the background of the table view appears correctly.
1498    
1499            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
1500            object that can be used by derived classes to place any
1501            controls (including the grid) onto.
1502            (QueryTableFrame.__init__): Use the panel as the parent window
1503            for all the controls. Reparent the grid so that the panel is
1504            the parent. Call UpdateStatusText() to correctly initialize
1505            the status bar.
1506    
1507    2003-06-13  Jonathan Coles   <[email protected]>
1508    
1509            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
1510            from wxFrame (as opposed to wxDialog like the other classes)
1511            but otherwise behaves like the other classes. This is needed
1512            for the TableView which isn't really a dialog and needs to
1513            have a status bar and control buttons.
1514    
1515            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
1516            instance variable to keep track of how many rows are selected.
1517            Subscribe once to the the events we are interested in.
1518            (ThubanGrid.OnRangeSelect): Only handle event if event handling
1519            hasn't been turned off.
1520            (ThubanGrid.OnSelectCell): Only handle event if event handling
1521            hasn't been turned off.
1522            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
1523            as an event listener (which changes the event handler stack)
1524            simply set an instance variable to False. This is checked in
1525            the event handlers.
1526            (ThubanGrid.GetNumberSelected): Return the number of currently
1527            selected rows.
1528            (TableFrame): Inherit from ThubanFrame so we can have a
1529            status bar and control buttons.
1530            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
1531            Explicitly set which items are selected in the operator choice and
1532            action choice so there is always a valid selection. Fixes RTbug #1941.
1533            Subscribe to grid cell selection events so we can update the
1534            status bar.
1535            (QueryTableFrame.UpdateStatusText): Update the status bar with
1536            how many rows are in the grid, how many columns, and how many
1537            rows are selected.
1538            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
1539            Call UpdateStatusText when cells are (de)selected.
1540            (QueryTableFrame.OnQuery): Use the string value in the value
1541            combo if either the selected item index is 0 or if the string
1542            cannot be found in the predefined list (this happens if the
1543            user changes the text). Fixes RTbug #1940.
1544            Only turn off the grid event listeners if there a query comes
1545            back with a none empty list of ids. in the case that the list
1546            is empty this causes a grid.ClearSelection() call to actually
1547            clear the grid selection which causes the selected items in
1548            the map to be deselected. Fixes RTbug #1939.
1549    
1550            * test/test_save.py (XMLWriterTest.Encode): Check return values.
1551            Fixes RTbug #1851.

1554    
1555            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
1556            self.selected_shape with the current selection to make sure the
1557            contents of the dialog are up to date when it's shown for the
1558            first time.
1559            The dialog used to work without this by luck. The recent fix to
1560            the connector module 'broke' a 'feature' the identify view was
1561            relying on, i.e that subscribing to a message in response to
1562            receiving a message of that type would mean that the new
1563            subscriber would also be called for the same message.

1566    
1567            * extensions/thuban/gdalwarp.cpp: Removed debug printing as
1568            the image is rendered. Fixes RTbug #1937.
1569    
1570    2003-06-12  Jonathan Coles   <[email protected]>
1571    
1572            * Thuban/Lib/fileutil.py: As is done under Windows, create the
1573            user directory if it doesn't exist on a posix system.
1574            Fixes RTbug #1815.
1575    
1576            * Thuban/Model/resource.py (get_user_proj_files): Moved the
1577            called to get_application_dir here, so that the directory
1578            will only be called if this method is invoked.
1579    
1580            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
1581            the projfilepath if no projection is selected.
1582    
1583    2003-06-12  Jonathan Coles   <[email protected]>
1584    
1585            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
1586            the scalebar if the current map has no projection set.
1587    
1588            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
1589            projfilepath label to just the basename of the projection file
1590            rather than include the entire path.
1591    
1592            * Thuban/Model/resource.py: Fix missed proj functions that
1593            needed to be renamed.
1594    
1595    2003-06-12  Jonathan Coles   <[email protected]>
1596    
1597            * Thuban/Model/classification.py: Removed assert statements that
1598            tested if the variable was an instance of Color.
1599    
1600            * Thuban/Model/color.py (Color): Remove commented code that isn't
1601            used.
1602            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
1603            Fixes RTbug #1835.
1604            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
1605            Needed now that the class doesn't inherit from Color.

1607    2003-06-12  Jonathan Coles   <[email protected]>
1608    
1609            * test/test_save.py (XMLWriterTest.testEncode): Explicitly
1610            check unicode strings.
1611    
1612            * test/test_layer.py: Check for existence of gdal.

1614    2003-06-12  Jonathan Coles   <[email protected]>
1615        
1616            * Thuban/Model/xmlreader.py: New. Contains the XMLReader class
1617            that was in load.py
1618    
1619            * Thuban/Model/xmlwriter.py: New. Contains the XMLWriter class
1620            that was in save.py
1621    
1622    2003-06-12  Jonathan Coles   <[email protected]>
1623    
1624            This is largely a collection of bug fixes. We also handle the
1625            case where gdal is not on the system. The XMLReader and XMLWriter
1626            classes were moved into there own files to resolve some circular
1627            import references and because they shouldn't really be in the
1628            file that is dediciated to reading/writing session files since
1629            they are also used elsewhere.
1630    
1631            * Thuban/Model/classgen.py: Renamed functions to follow the
1632            function_names_with_underscores style. Fixes RTbug #1903.
1633            (calculate_quantiles): Raise ValueError if 'percents' is invalid.
1634    
1635            * Thuban/Model/layer.py: Import gdal only if it available.
1636            (RasterLayer): Handle the case where the gdal library is unavailable.
1637            Addresses RTbug #1877.
1638    
1639            * Thuban/Model/load.py (XMLReader): Moved into seperate file
1640            xmlreader.py.
