2    
3            * Thuban/UI/application.py
4            (ThubanApplication.run_db_param_dialog): New. Suitable as a
5            db_connection_callback. Main difference is that the dialog run
6            from this method doesn't have a parent so it can be used even when
7            there is no main window
8            (ThubanApplication.OpenSession): Use self.run_db_param_dialog if
9            no db_connection_callback was given. This way the dialog pops up
10            even when the .thuban file was given as a command line parameter.
11    
12    2003-08-25  Bernhard Herzog  <[email protected]>
13    
14            * Thuban/UI/view.py (MapCanvas.OnLeftUp): Release the the mouse
15            before calling MouseLeftUp. MouseLeftUp may pop up modal dialogs
16            which leads to an effectively frozen X session because the user
17            can only interact with the dialog but the mouse is still grabbed
18            by the canvas.
19            Also, call the tool's Hide method before MouseLeftUp because
20            MouseLeftUp may change the tool's coordinates.
21    
22    2003-08-25  Bernhard Herzog  <[email protected]>
23    
24            * Thuban/UI/application.py (ThubanApplication.OpenSession): Catch
25            LoadCancelled exceptions and handle them by returning immediately.
26    
27    2003-08-25  Bernhard Herzog  <[email protected]>
28    
29            GUI part of loading sessions with postgis connections which may
30            require user interaction to get passwords or updated parameters
31    
32            * Thuban/UI/dbdialog.py (DBDialog): Reimplement to make it look a
33            bit nucer and be more generic.
34            (DBFrame.OnAdd): Adapt to new DBDialog interface
35    
36            * Thuban/UI/application.py (ThubanApplication.OpenSession): New
37            optional parameter db_connection_callback which is passed to
38            load_session.
39    
40            * Thuban/UI/mainwindow.py (MainWindow.run_db_param_dialog): New.
41            Suitable as a db_connection_callback
42            (MainWindow.OpenSession): Use self.run_db_param_dialog as the
43            db_connection_callback of the application's OpenSession method
44    
45    
46    2003-08-25  Bernhard Herzog  <[email protected]>

54            password for a database connection
55            (SessionLoader.__init__): Add the new XML elements to the
56            dispatchers dictionary
57            (SessionLoader.check_attrs): Two new conversions, ascii to convert
58            to a byte-string object and idref as a generic id reference
59            (SessionLoader.start_dbconnection)
60            (SessionLoader.start_dbshapesource): New. Handlers for the new XML
61            elements
62            (load_session): Add the db_connection_callback to pass through the
63            SessionLoader
64

76    
77            * Thuban/Model/load.py (SessionLoader.check_attrs): Raise a
78            LoadError when a required attribute is missing. The code used to
79            be commented out for some reason, but probably should have been
80            active.
81    
82            * test/test_load.py (TestLoadError.test): Test the message in the
83            LoadError too to make sure it really is about the missing

370            Fix some bugs in Thuban and the test suite that were uncovered by
371            changes introduced in Python 2.3:
372    
373            * Thuban/Model/table.py (DBFTable.__init__): Make sure the
374            filename is an absolute name
375    
376            * Thuban/Model/layer.py (RasterLayer.__init__): Make sure the
377            filename is an absolute name
378

391    
392    2003-08-15  Bernhard Herzog  <[email protected]>
393    
394            Change the way shapes are returned by a shape store. The

396            objects instead of a list of shape ids.
397

456            Return a flag useraw in addition to the callable and the parameter
457            to indicate whether the callable can deal with the raw shape data
458            or uses the higher level python lists of coordinates. The callable
459            now should accept either the raw data or the return value of the
460            shape's Points() method.

592            information.
593            (ShapefileShape.compute_bbox): Simplified to not cache any

602            method.
603    
604            * test/test_shapefilestore.py

606            format feature of shapes.
607    
608            * Thuban/Model/layer.py: Remove the unused import of Shape from
609            data. It was only there for interface compatibility but it's not
610            used inside of Thuban and the generic Shape class has gone away.
611    
612            * Thuban/UI/renderer.py (MapRenderer.low_level_renderer): Check
613            the raw data format and only use an optimized version of its a

627            (ThubanTestProgram): New classes that extend the respective
628            classes from unittest. These new version support skipping tests
629            under certain expected conditions. In the Thuban test suite we
630            uses this for tests that require the optional gdal support.
631            (run_tests): Use ThubanTestProgram instead of the unittest.main()
632

653            only a specialization of BaseRenderer for rendering to an actual
654            wx DC.
655            (ScreenRenderer.draw_shape_layer): Use self.low_level_renderer()
656            to get the shapetype specific rendering functions.

668            rendering into a separate method _do_redraw so that error handling
669            is a bit easier. When an exception occurs, set error_on_redraw to
670            true. When it's true on entry to OnIdle do nothing and return
671            immediately.
672    
673            * Thuban/Model/data.py (ShapefileStore.Shape): For consistency, a
674            Shape object will always have the coordinates as a list of list of

710    
711            * Thuban/UI/projdialog.py (UTMPanel._OnPropose): Added test for
712            a bounding box. A dialog is raised in case, no bounding box

715    
716    2003-08-05  Bernhard Herzog  <[email protected]>
717    
718            * Thuban/Model/color.py (Color.__repr__): Make the repr of a color
719            object look like a Color instantiation. Formerly it looked like a
720            tuple.

743    
744    2003-08-01  Bernhard Herzog  <[email protected]>
745    
746            First step towards PostGIS integration. More abstraction by movin
747            more code from the layer to the shapestore. More methods of the
748            layer are now simply delegated to the equivalent method of the
749            shapestore. The SHAPETYPE_* constants are now in data not in
750            layer.

786            (TestLayer.test_derived_store): Remove the test for the exception
787            when instantiating the DerivedShapeStore with an incompatible
788            table which is now in test_derivedshapestore.py. Add some more
789            tests of the layer methods to determine whether they work for a
790            DerivedShapeStore as well.
791    
792    2003-07-31  Jonathan Coles   <[email protected]>
793    
794            * Doc/manual/thuban-manual.xml: Fix the list of required packages
795            by just listing the name and where they can be found.
796    
797    2003-07-31  Frank Koormann   <[email protected]>
798    
799            * Doc/manual/thuban-manual.xml:
800            Changed the screenshot elements to figure.
801            Changed some variablelist elements to itemizedlist.
802            Added section on GDAL formats.
803    
804    2003-07-31  Jonathan Coles   <[email protected]>
805    
806            * Doc/manual/thuban-manual.xml: Added a few sentences about
807            the Fix Border Color option when generating classes.
808    
809    2003-07-30  Jonathan Coles   <[email protected]>
810    
811            * Thuban/Model/classgen.py: Add docstrings. Rename specific
812            Ramp instances to use lower_case_style.
813    
814            * Thuban/UI/classgen.py: Use renamed Ramp instances.
815            
816            * Thuban/UI/classifier.py: Add docstrings.
817    
818            * Thuban/UI/dock.py: Add docstrings.
819    
820            * test/test_classgen.py: Use renamed Ramp instances.
821    
822    2003-07-30  Bernhard Herzog  <[email protected]>
823    
824            * Thuban/Lib/connector.py (QueueingPublisher): Removed. This class
825            was never used in Thuban.
826    
827    2003-07-30  Bernhard Herzog  <[email protected]>
828    
829            * Thuban/UI/join.py (JoinDialog.__init__): Use the table's Title()
830            method directly instead of going through the transient_table
831            method. This faster because transient_table may force the copy of
832            a DBF file into the transient database and setting a table's title
833            doesnm't affect the title of the associated transient table, so
834            this fixes RT #2042
835    
836            * Thuban/UI/main.py (__version__): Don't import the already
837            removed show_exception_dialog.
838    
839    2003-07-29  Jonathan Coles   <[email protected]>
840    
841            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
842            Put back this method and remove the equivalent function since we
843            are setting the exception hook from within this class (OnInit).
844    
845    2003-07-29  Jonathan Coles   <[email protected]>

851            Doc/manual/images/8_int_error.png: New screen shots.
852    
853            * Doc/manual/thuban-manual.xml: Fixed typos and wording, clarified
854            some points, and added more screen shots.
855    
856    2003-07-29  Bernhard Herzog  <[email protected]>
857    
858            * Thuban/Model/data.py: Remove the now unused import of warnings
859    
860    2003-07-29  Bernhard Herzog  <[email protected]>
861    
862            * Thuban/Model/data.py (SimpleStore): Removed. This class has been
863            deprecated since before the 0.8 release and isn't used in Thuban
864            itself anymore.
865    
866            * Thuban/Model/transientdb.py: Remove some unnecessary imports
867    
868    2003-07-29  Jonathan Coles   <[email protected]>
869    
870            * Thuban/UI/application.py (ThubanApplication.OnInit): set the
871            python exception hook here so that we are sure to catch any
872            Thuban exception that happen during initialization.
873    
874            * Thuban/UI/main.py (main): Don't set the exception hook here,
875            it will get set in ThubanApplication.OnInit.
876    
877    2003-07-29  Jonathan Coles   <[email protected]>
878                                                                                
879            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
880            Removed and called it show_exception_dialog() so that the exception
881            handler can be set before the class is created.
882                                                                                
883            * Thuban/UI/main.py (main): Install the exception handler before
884            a ThubanApplication is created.
885

938            manual and images.
939    
940    2003-07-24  Bernhard Herzog  <[email protected]>
941    
942            * Thuban/Model/range.py, Thuban/version.py: Remove the #! line as
943            it annoys lintian which warns about these files not being
944            executable. The #1 isn't necessary here since if you absolutely
945            must execute them you can always say "python <filename>".
946    
947            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Remove
948            superfluous code to set brush and pen for point shapes
949    
950            * Thuban/UI/viewport.py: Remove commented out code that wouldn't
951            belong in viewport anyway
952    
953    2003-07-24  Frank Koormann   <[email protected]>
954

962    2003-07-22  Jonathan Coles   <[email protected]>
963    
964            * Doc/manual/thuban-manual.xml: Continue to write first revision
965            of the manual.
966    
967            * Thuban/UI/renderer.py (MapRenderer.render_map): Wrap method
968            with Begin/EndDrawing() calls to ensure we aren't doing to
969            many updates to the dc during rendering.
970            (ScreenRenderer.draw_shape_layer): self.draw_point_shape takes
971            a pen and brush argument so they need to be passed to the function.
972    
973            * Thuban/UI/viewport.py (ViewPort.calc_min_max_scales): New.
974            Calculates the minimum and maximum scale values. Factored out
975            of set_view_transform so that it could be used to zoom all the
976            way into a single point.
977            (ViewPort.set_view_transform): Call calc_min_max_scales().
978            (ViewPort.FitSelectedToWindow): Zoom to the maximum scale
979            if only a single point is selected.

1012            MAP_REPLACED message it's no longer needed
1013            (MainWindow.OpenSession, MainWindow.NewSession):
1014            prepare_new_session has been removed.
1015    
1016            * Thuban/UI/classifier.py (Classifier.__init__): Subscribe to
1017            MAP_REPLACED so that we can close the dialog if a new map is set.
1018            (Classifier.unsubscribe_messages): Unsubscribe from MAP_REPLACED
1019            (Classifier.map_replaced): Handle MAP_REPLACED by closing the
1020            dialog

1023            (SimpleViewPortTest.test_default_size): Add doc-strings
1024            (ViewPortTest.setUp): Bind map to self.map so we can use it in
1025            tests. Subscribe to MAP_REPLACED messages too.
1026            (ViewPortTest.tearDown): No need to explicitly unsubscribe

1028    
1029    2003-07-18  Bernhard Herzog  <[email protected]>
1030    
1031            * test/test_viewport.py (SimpleViewPortTest.test_default_size):
1032            Move this test from ViewPortTest.setUp to this new separate test
1033            case. setUp is not the place for the actual tests.
1034            (ViewPortTest.test_inital_settings, ViewPortTest.setUp): Move some
1035            more of the test from setUp to the new test test_inital_settings.
1036            (ViewPortTest.test_win_to_proj, ViewPortTest.test_proj_to_win)
1037            (ViewPortTest.test_proj_conv): Split test_proj_conv into
1038            test_win_to_proj and test_proj_to_win and make the tests easier to
1039            understand
1040            (ViewPortTest.testFitRectToWindow, ViewPortTest.testZoomFactor)

1050    2003-07-18  Bernhard Herzog  <[email protected]>
1051    
1052            * test/runtests.py: The test suite can now be run without an X
1053            connection. To make sure this remains true, remove the DISPLAY
1054            environment variable so that an error occurs if the wxGTK is
1055            imported accidentally
1056    
1057    2003-07-18  Bernhard Herzog  <[email protected]>
1058

1063    2003-07-18  Bernhard Herzog  <[email protected]>
1064    
1065            * test/test_export.py Remove unused imports. The OutputTransform
1066            function is now in viewport.py and is called output_transform
1067            (TestScalebar.test_output_transform)
1068            (TestScalebar.test_OutputTransform): Renamed to
1069            test_output_transform and updated to use output_transform instead
1070            of OutputTransform
1071    
1072            * Thuban/UI/view.py (OutputTransform): Moved to viewport.py and
1073            renamed.
1074            (MapCanvas.Export, MapPrintout.draw_on_dc): OutputTransform was
1075            renamed to output_transform
1076    
1077            * Thuban/UI/viewport.py (OutputTransform, output_transform):
1078            Rename to output_transform
1079

1082            * Thuban/Model/layer.py (Layer.__init__): Rename
1083            classificationField to classificatin_column and init it here so
1084            that it can be used in SetClassificationColumn

1091            _classification_changed. Update the callers.
1092            (Layer.SetShapeStore): Further field->column renames.
1093    
1094            * Thuban/Model/load.py (SessionLoader.start_classification)
1095            (SessionLoader.start_clpoint): Updates because of
1096            field->column method name changes in the Layer class
1097    
1098            * Thuban/Model/save.py (SessionSaver.write_classification): Updates

1122            (TestLayerModification.test_set_classification): New test for
1123            SetClassification and SetClassificationField.
1124    
1125    2003-07-18  Bernhard Herzog  <[email protected]>
1126    
1127            * test/test_classgen.py (TestFixedRamp.test): Extend test to check
1128            the non-fixed values as well. The old test would have accepted a
1129            fixed ramp that only returnes the fixed properties
1130    
1131    2003-07-17  Jonathan Coles   <[email protected]>
1132    
1133            * Doc/manual/mainwindow.png, Doc/manual/mainwindow.xcf: Screen
1134            shots for the manual. The XCF file is the source image and
1135            has additional layers to support changes.
1136    
1137            * Doc/manual/thuban-manual.xml: Wrote an initial Introduction.
1138    
1139            * Thuban/UI/classifier.py (Classifier.__BuildClassification):
1140            Return both the new class and the field name.
1141    
1142            * Thuban/UI/mainwindow.py (MainWindow.ToggleLegend): Don't
1143            fit the map to the window as this changes any zoom level that
1144            the user may have set.
1145    
1146    2003-07-16  Jonathan Coles   <[email protected]>
1147    
1148            * Thuban/Model/classgen.py (generate_singletons,
1149            generate_uniform_distribution, generate_quantiles): Remove
1150            fixes parameter, but maintain the same functionality by having
1151            the calling function pass a FixedRamp object for the ramp.
1152            (FixedRamp): New. Adapts a ramp to have fixed property values.
1153    
1154            * Thuban/Model/classification.py: Use new CLASS_CHANGED message.
1155            (Classification): Inherit from Publisher.
1156            (Classification.__init__): Remove the layer parameter.
1157            Classifications no longer need to have a parent layer.
1158            (Classification.GetField, Classification.GetFieldType,
1159            Classification.SetFieldInfo): Removed. The field name is stored
1160            in the layer, and the type can be retreived by calling
1161            Layer.GetFieldType().
1162            (Classification._set_layer, Classification.GetLayer): Removed.
1163            Classifications no longer have a parent layer.
1164    
1165            * Thuban/Model/layer.py (Layer.Destroy): Unsubscribe from the
1166            classification.
1167            (Layer.SetShapeStore): Reset the classification first while
1168            we still have the old shape store to work with.
1169            (Layer.GetClassificationField, Layer.SetClassificationField):
1170            New. Method for getting/setting the field to classify on.
1171            (Layer.SetClassification): Simplified now that the layer
1172            simply has to hold a reference to the classification and not
1173            tell the classification who owns it.
1174            Fixes RTbug #2023.
1175    
1176            * Thuban/Model/load.py (SessionLoader.start_classification):
1177            Set the field name on the layer, not the classification.
1178    
1179            * Thuban/Model/messages.py: Add CLASS_CHANGED for when a
1180            classification is modified.
1181    
1182            * Thuban/Model/save.py (SessionSaver.write_classification):
1183            Get the field name and type from the layer.
1184    
1185            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Renamed
1186            parameter records to rows and add docstring. Fixes RTbug #1997.
1187    
1188            * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Use a fixed
1189            ramp when we need to fix certain values of a ramp rather than
1190            using the old fixes parameter. Fixes RTbug #2024.
1191    
1192            * Thuban/UI/classifier.py (ClassGrid.CreateTable): Add fieldType
1193            parameter.
1194            (ClassTable.Reset): Add fieldType parameter and use it, rather
1195            than asking the classification.
1196            (Classifier.__init__): Remember the original class's field
1197            and ask the layer for the field type, rather than the classification.
1198            (Classifier.__SetGridTable): Retrieve the field and field type
1199            for the table because they are not in the classification.
1200            (Classifier._OnTry, Classifier._OnRevert): Set the classification
1201            field on the layer in addition to the classification itself.
1202    
1203            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Get the
1204            classification field from layer.
1205    
1206            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Get the
1207            classification field from layer. Split up tests and remove
1208            *-imports. Fixes RTbug #1992.
1209    
1210            * test/test_classgen.py (TestFixedRamp): Test for the FixedRamp class.
1211    
1212            * test/test_classification.py
1213            (TestClassification.test_classification): Remove tests for methods
1214            that no longer exist.
1215    
1216            * test/test_layer.py (SetShapeStoreTests.setUp): Classification
1217            __init__ no longer has a field parameter, use SetClassificationField.
1218            (SetShapeStoreTests.test_sanity): Use layer object to get class
1219            field info.
1220    
1221            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Use
1222            SetClassificationField on layer to set class field info.

1229            coarse structure.
1230    
1231    2003-07-15  Bernhard Herzog  <[email protected]>
1232    
1233            * test/support.py (FloatComparisonMixin): This is a mix-in class
1234            and therefore should not be derived from any other class.
1235    
1236            * test/test_range.py (RangeTest): FloatComparisonMixin is a
1237            mix-in, so derive from TestCase as well.
1238    
1239    2003-07-15  Bernhard Herzog  <[email protected]>
1240    
1241            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Rework the
1242            draw_func handling a bit to remove one layer of indirection. This
1243            makes the renderer about 10% faster in the non-classifying case
1244            and the code a bit cleaner
1245            (MapRenderer.draw_point_shape): Add the pen and brush parameters
1246            and set them in the dc. Now the draw_point_shape method and
1247            wxproj's draw_polygon_shape function have basically the same
1248            signature so that both can be directly used as draw_func
1249    
1250    2003-07-15  Bernhard Herzog  <[email protected]>
1251    
1252            * Thuban/Model/save.py (SessionSaver.write_classification): Encode
1253            string values (in addition to the labels) as UTF 8
1254    
1255            * Thuban/Model/load.py (SessionLoader.start_clpoint): Decode the
1256            values if the field type is string
1257    
1258            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Test
1259            saving a session with non-ascii string classification values.
1260    
1261            * test/test_load.py (TestClassification.file_contents)
1262            (TestClassification.test): Check for non-ascii values in string
1263            classifications
1264    
1265    2003-07-14  Jonathan Coles   <[email protected]>
1266    
1267            * test/test_view.py: New. Tests for ViewPort.
1268    
1269    2003-07-14  Frank Koormann   <[email protected]>
1270    
1271            * Thuban/Model/load.py (SessionLoader.start_map): Encode map
1272            title to latin1.  Fixes https://intevation.de/rt/webrt?serial_num=2013
1273    
1274            * test/test_load_0_8.py (TestUnicodeStrings): New, test load of

1278    2003-07-10  Jonathan Coles   <[email protected]>
1279    
1280            * Thuban/UI/viewport.py (Tool.MouseUp): Should have called
1281            drag_stop, not drag_move when the mouse is released.
1282    
1283    2003-07-10  Jonathan Coles   <[email protected]>
1284    
1285            The most important part of this is the seperation of view.py into
1286            two pieces. viewport.py now has a class called ViewPort which
1287            contains all the non-wx parts of view.py and can therefore be
1288            tested. view.py contains only the wx-specific parts and is fairly
1289            simple.
1290    
1291            * Thuban/UI/view.py: Stripped out all non-wx functionality. Fixes
1292            RTTbug #1992.

1294            RTTbug #1992.
1295

1297            generate_uniform_distribution, generate_quantiles):
1298            Added 'fixes' parameter so that property attributes can
1299            be held constant over the generated classification groups.
1300            (CustomRamp.GetProperties): Remove unused variables.
1301    
1302            * Thuban/Model/map.py (Map.SetProjection): Send the old
1303            projection as an argument to listeners of the MAP_PROJECTION_CHANGED
1304            event.
1305    
1306            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Added 'records'
1307            parameter which is a list of records that restricts which
1308            records are saved. Fixes RTbug #1997.
1309    
1310            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
1311            Port exception dialog from GREAT-ER. Fixes RTbug #1993.
1312    
1313            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Add controls
1314            to allow the user to fix line color/width on generated groups.

1322            the table window when it is selectd to be shown.
1323    
1324            * Thuban/UI/tableview.py (QueryTableFrame.__init__): Add an
1325            Export Selection button and move the export buttons underneath
1326            the table.
1327            (QueryTableFrame.UpdateStatusText): Added event argument so
1328            that it can respond to grid selection events. The status text
1329            is now updated even when the table is not associated with a
1330            layer as was previously assumed.
1331            (QueryTableFrame.OnGridSelectRange, OnGridSelectCell): Removed.
1332            UpdateStatusText responds to these events.
1333            (QueryTableFrame.OnSaveAs): Renamed to doExport.
1334            (QueryTableFrame.doExport): Helper function that saves the
1335            entire table, or selected rows, to a file.
1336            (QueryTableFrame.OnExport, QueryTableFrame.OnExportSel): New.

1338    
1339            * extensions/thuban/gdalwarp.cpp (ProjectRasterFile): Make sure
1340            the function doesn't return NULL without first setting a Python
1341            Error.

1347            optional epsilon argument to specify floating point accuracy.
1348            (FloatComparisonMixin.assertFloatSeqEqual): Call assertFloatEqual
1349            for each item test.
1350    
1351            * test/test_csv_table.py (TestCSVTable.test_table_to_cvs): Add
1352            tests for saving selected records.
1353    
1354            * test/test_dbf_table.py (TestTableToDBF.test_table_to_dbf): Add
1355            tests for saving selected records.
1356    
1357            * test/test_map.py (TestMapWithContents.test_set_projection):
1358            MAP_PROJECTION_CHANGED events send the old projection.
1359

1364            * test/test_table.py (TableTest): Update tests to use non-deprecated
1365            functions.
1366    
1367    2003-07-08  Bernhard Herzog  <[email protected]>
1368    
1369            * Thuban/Model/transientdb.py (TransientTableBase.Width): The type
1370            constants in the column objects are the standard ones defined in
1371            the table module.
1372    
1373            * test/test_transientdb.py
1374            (TestTransientTable.test_transienttable_to_dbf): New. Test whether
1375            exporting transient tables as DBF works. This should catch the bug
1376            just fixed in TransientTableBase.Width.
1377    
1378    2003-07-08  Bernhard Herzog  <[email protected]>
1379    
1380            * Thuban/Model/classgen.py (CustomRamp.GetProperties): Compute the
1381            interpolated colors correctly.
1382    
1383            * test/test_classgen.py (TestCustomRamp.test_color_interpolation):

1484    
1485    2003-07-02  Jonathan Coles   <[email protected]>
1486    
1487            * Thuban/Model/classgen.py (generate_singletons,
1488            generate_uniform_distribution, generate_quantiles,
1489            GenQuantiles0): The denominator was one to high when
1490            calculating the index for the ramp causing the index
1491            to never to reach one.
1492    
1493    2003-07-02  Jonathan Coles   <[email protected]>
1494    
1495            Changed the singature of ClassGroupRange.__init__ and
1496            ClassGroupRange.SetRange() so that the min/max values are
1497            passed as a tuple. This makes a better calling scheme for
1498            when a Range object is passed instead.
1499    
1500            * Thuban/Model/classgen.py: Fixed parameters to

1502    
1503            * Thuban/Model/classification.py (ClassGroupRange.__init__):

1513            the classification instance variable to the new class
1514            before calling _set_layer otherwise subscribers to a
1515            LAYER_CHANGED event will not see any difference.
1516    
1517            * test/test_classification.py: Fix tests of ClassGroupRange
1518            so that they use the new signature.

1531    
1532            * Thuban/Model/classgen.py: Fixes RTbug #1972, 1971.
1533            Import used objects/class from color.
1534            (generate_singletons): We don't
1535            need the numGroups parameter anymore because we are using
1536            the new ramps with GetProperties().
1537            (generate_uniform_distribution): Use new ramp method
1538            GetProperties().
1539            (generate_quantiles, GenQuantiles0): Use new ramp method
1540            GetProperties().
1541            (CustomRamp.SetNumGroups): Removed. The ramps now map
1542            a value from 0 to 1 to class properties so the number
1543            of groups is not needed ahead of time.
1544            (CustomRamp.next): Removed. CustomRamp does not support
1545            interation anymore.
1546            (CustomRamp.GetProperties): Returns a ClassGroupProperties
1547            object based on the index value from 0 to 1 that is
1548            passed to it.
1549            (GreyRamp, RedRamp, GreenRamp, BlueRamp, GreenToRedRamp):
1550            Made into instances of Monochromatic class instread of
1551            deriving from it.
1552            (HotToCold.SetNumGroups): Removed. See CustomRamp.
1553            (HotToCold.next): Removed. See CustomRamp.
1554    
1555            * Thuban/Model/classification.py: Fixes RTbug #1973, 1971.
1556            (Classification.SetField, Classification.SetFieldType):
1557            Replaced with SetFieldInfo.
1558            (Classification.SetFieldInfo): New. Does a better job of
1559            what SetField and SetFieldType used to do by combining
1560            their function since they should really always be done
1561            at the same time.
1562            (Classification.SetLayer): Renamed to _set_layer.
1563            (Classification._set_layer): Should only be called from
1564            Layer's SetClassification. This does not cause a recursive
1565            call as SetLayer did because we know that Layer knows about
1566            the classification.
1567    
1568            * Thuban/Model/color.py: Fixes RTbug #1971.
1569            (_Transparent): Renamed from Transparent so it doesn't
1570            conflict with the module variable.
1571            (Transparent, Black): Renamed from Color.Transparent,
1572            Color.Black so they are not class variables.
1573    
1574            * Thuban/Model/layer.py: Fixes RTbug #1971, 1973.
1575            (Layer.Destroy): We don't need to call SetClassification
1576            anymore to clear out the back reference in the classifcation
1577            to the layer. It's better to set it to None using _set_layer,
1578            and we won't be creating another clas object too.
1579            (Layer.SetClassification): Classification._set_layer is not
1580            recursive so remove all the locking variables. Also clean
1581            up the code so that it remains unchanged if something fails.
1582    
1583            * Thuban/Model/load.py: Fixes RTbug #1971.
1584            (SessionLoader.start_classification): Call
1585            Classification.SetFieldInfo().
1586    
1587            * Thuban/Model/save.py: Removed import of Color which wasn't
1588            being used.
1589    
1590            * Thuban/UI/classgen.py: Fixes RTbug #1972.
1591            (ClassGenDialog.__init__): Color ramps are now instances
1592            already so we don't need to create any new objects.
1593            (ClassGenDialog.OnOK): Check for numGroups is no longer
1594            necessary because we never use it.
1595    
1596            * Thuban/UI/classifier.py: Fixes RTbug #1971.
1597            (Classifier.__BuildClassification, Classifier.__SetGridTable):
1598            Call Classification.SetFieldInfo() instead of SetFieldType.
1599    
1600            * Thuban/UI/renderer.py: Fixes RTbug #1971.
1601    
1602            * Thuban/UI/view.py: Fixes RTbug #1974, 1971.
1603            (MapCanvas.__init__): Subscribe to the idle time event. Set
1604            background color to white.
1605            (MapCanvas.OnPaint): Set a flag indicating that we should
1606            render the map during idle time. If we already have a bitmap
1607            just draw it now.
1608            (MapCanvas.OnIdle): New. Render the map only during idle time.
1609            This also fixes a problem with the busy cursor under gtk.
1610    
1611            * test/test_classgen.py (ClassGenTest.test_generate_singletons):
1612            Fix calls to generate_singletons because the signature changed.
1613    
1614            * test/test_classification.py: Fix color references and
1615            change calls to Classification.[SetField|SetFieldType] to
1616            SetFieldInfo.
1617    
1618            * test/test_load.py: Fix color references.
1619    
1620            * test/test_load_0_2.py: Fix color references.
1621    
1622            * test/test_save.py (SaveSessionTest.testClassifiedLayer):
1623            Change calls to Classification.[SetField|SetFieldType] to
1624            SetFieldInfo.
1625

1628            MERGE from the greater-ms3 branch.
1629    
1630            * test/test_transientdb.py
1631            (TestTransientTable.test_transient_joined_table_with_equal_column_names):
1632            New. Test join of two tables with partly equal column names.
1633    
1634            * Thuban/Model/transientdb.py (TransientJoinedTable.create):
1635            If duplicates in left and right tables column names are found,
1636            append '_' (underscores) to the name until it is unique.
1637            Create always new internal names for the resulting table and reference
1638            columns in the join statement with <table>.<column>
1639    
1640    2003-07-01  Bernhard Herzog  <[email protected]>
1641

1643            (TestTransientTable.test_transient_joined_table_same_column_name):
1644            New. Test whether joining on columns with the same names in both
1645            tables works.
1646            
1647            * Thuban/Model/transientdb.py (TransientJoinedTable.create): Make
1648            sure to use the right internal names even when joining on field
1649            with the same names in both tables. Also, detect duplicate names
1650            in the joined table correctly.
1651    
1652    2003-07-01  Frank Koormann   <[email protected]>
1653    
1654            * Thuban/UI/renderer.py (ExportRenderer.render_legend):

1657    2003-06-30  Jonathan Coles   <[email protected]>
1658    
1659            * Thuban/version.py (make_tuple): Takes a version string
1660            and splits it into a tuple of at most three integers.
1661            Used make_tuple() to make tuple versions of the version
1662            numbers.
1663    
1664            * Thuban/UI/about.py: Add Thuban email addresses.
1665    
1666    2003-06-30  Jonathan Coles   <[email protected]>
1667    
1668            * Thuban/version.py: SQLite/PySQLite version dependencies
1669            were too high.
1670    
1671    2003-06-30  Jonathan Coles   <[email protected]>
1672    
1673            * Thuban/version.py: Update version to 0.8.1
1674            
1675            * MANIFEST.in: Added Projections so that default.proj is
1676            included.

1679    
1680            New About box with lots more information including library
1681            versions and credits. More/better version checking before
1682            Thuban starts.
1683    
1684            * Thuban/UI/about.py: New. New About box that displays
1685            library version information and credits.
1686    
1687            * Thuban/version.py: Added new 'versions' dictionary which
1688            contains the verions of various libraries which are checked
1689            when the module loads.
1690            (verify_versions): Check all version numbers and returns
1691            a list of errors.
1692    
1693            * Thuban/UI/classifier.py (Classifier.__EnableButtons):
1694            Reset the status of the buttons as the situation warrants,
1695            but in a better more reliable way by not relying on the
1696            current status to determine what needs to change.
1697    
1698            * Thuban/UI/main.py (wxCHECK_VERSION): Removed. Not needed.
1699            (verify_versions): Remove most of the code since it is
1700            now in Thuban.version.verify_versions.o
1701    
1702            * Thuban/UI/mainwindow.py (MainWindow.About): Call new
1703            About box in Thuban.UI.about.

1714    
1715    2003-06-25  Jonathan Coles   <[email protected]>
1716    
1717            * Thuban/UI/classifier.py (Classifier.EditSymbol): The parent
1718            of the SelectPropertiesDialog should be self so the window
1719            appears on top.
1720            (ClassGroupPropertiesCtrl.DoEdit): The parent
1721            of the SelectPropertiesDialog should be self so the window
1722            appears on top.
1723    
1724            * Thuban/UI/resource.py: Cleaned up how we determine file
1725            extensions.
1726            (GetImageResource): Return an wxImage from our Resources.
1727    
1728    2003-06-24  Jonathan Coles   <[email protected]>
1729    
1730            * Thuban/UI/renderer.py (ExportRenderer.render_legend):
1731            Check that a layer has a classification before trying
1732            to get it. Raster layers don't have classifications.
1733    
1734    2003-06-23  Jonathan Coles   <[email protected]>
1735            
1736            * setup.py: Add Resources/XML to resource list.

1742    2003-06-23  Jonathan Coles   <[email protected]>
1743    
1744            * MANIFEST.in: Update with Resources/XML
1745    
1746            * setup.py: Don't include Locale resources yet as we don't
1747            have any and it causes problems building the distribution
1748            for Windows. Update version to 0.8.0.
1749    
1750            * Doc/thuban.dtd: Removed since it is now in Resources/XML.
1751    
1752            * Thuban/UI/mainwindow.py: Add blank line at the end because
1753            file was not being read correctly building the Windows
1754            distribution.
1755    
1756    2003-06-23  Jonathan Coles   <[email protected]>
1757    
1758            * Thuban/UI/mainwindow.py (MainWindow.About): Fix text.
1759

1762    
1763    2003-06-23  Jonathan Coles   <[email protected]>
1764    
1765            * Thuban/UI/common.py (ThubanBeginBusyCursor): Call wxSafeYield
1766            to make sure that we don't create reentrant possibilities with
1767            wxYield.
1768    
1769            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxBeginBusyCursor()
1770            directly to avoid the wxSafeYield() call which generates an
1771            OnPaint event causing infinite recursion. Don't try to catch
1772            exception anymore. This was for before there were limits on map
1773            scaling.
1774    
1775    2003-06-23  Bernhard Herzog  <[email protected]>
1776    
1777            Bug fix for RT #1961:
1778    
1779            * Thuban/Model/load.py (SessionLoader.start_derivedshapesource):
1780            Register DerivedShapestores with the session
1781    
1782            * Thuban/Model/session.py (Session.Tables): Make sure each table
1783            is only listed once.
1784    
1785            * test/test_load.py (TestJoinedTable.test): Add check_format call.
1786            Update file contents to match the one written out.
1787    
1788    2003-06-20  Bernhard Herzog  <[email protected]>
1789    
1790            * test/xmlsupport.py (SaxEventLister.startElementNS)
1791            (SaxEventLister.endElementNS): Do not include the qname. Python
1792            2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
1793            is (presumably incorrectly) None, whereas it's a string with the
1794            element name in the later versions.
1795    
1796            * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
1797            (TestEventList.test_even_list_namespace): Update tests to reflect
1798            the new behaviour
1799            (TestEventList.test_even_list_id_normalization): Fix doc-string
1800    
1801    2003-06-20  Jonathan Coles   <[email protected]>
1802    
1803            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
1804            by deriving classes to determine if that layer supports shapes.
1805            (Layer): Override HasShapes and return true.
1806    
1807            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
1808            instead of a direct call to wx[Begin|End]CusyCursor().
1809            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
1810            table data.
1811    
1812            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
1813            New. Wrappers around the wxWindows functions that allow us to
1814            make additional calls such as wxYield which gives the native
1815            system a chance to update the cursor correctly.
1816    
1817            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
1818            instead of a direct call to wx[Begin|End]CusyCursor().
1819    
1820            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
1821            instead of a direct call to wx[Begin|End]CusyCursor().
1822            (MapCanvas.find_shape_at): Check if the current search layer
1823            support shapes, otherwise go on to the next layer.
1824    
1825            * test/test_layer.py: Add tests in each type of layer for
1826            HasClassification() and HasShapes()
1827    
1828    2003-06-20  Jonathan Coles   <[email protected]>
1829    
1830            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
1831            turning on the busy cursor to allow the system to change the
1832            cursor before we begin painting. This fixes a problem that
1833            was occuring only under GTK. Fixes RTbug #1840.
1834    
1835    2003-06-20  Bernhard Herzog  <[email protected]>
1836    
1837            * Resources/XML/thuban-0.8.dtd: New DTD for the new file format

1843            sources they depend on.
1844            (SessionSaver.__init__): Add idmap instance variable to map from
1845            objects to the ids used in the file.

1851            (SessionSaver.write_data_containers): New. Write the data
1852            containers.
1853            (SessionSaver.write_layer): Layer elements now refer to a
1854            shapestore and don't contain filenames anymore.
1855    
1856            * Thuban/Model/load.py (LoadError): Exception class to raise when
1857            errors in the files are discovered
1858            (SessionLoader.__init__): Define dispatchers for elements with a
1859            thuban-0.8 namespace too.
1860            (SessionLoader.check_attrs): New helper method to check and
1861            convert attributes
1862            (AttrDesc): New. Helper class for SessionLoader.check_attrs
1863            (SessionLoader.start_fileshapesource)
1864            (SessionLoader.start_derivedshapesource)
1865            (SessionLoader.start_filetable, SessionLoader.start_jointable):

1868            addition to filename.
1869            (SessionLoader.start_table, SessionLoader.end_table): Removed.
1870            They were never used in the old formats and aren't needed for the
1871            new.
1872    
1873            * Thuban/Model/session.py (Session.DataContainers): New method to
1874            return all "data containers", i.e. shapestores and tables
1875    
1876            * test/xmlsupport.py (SaxEventLister.__init__)
1877            (SaxEventLister.startElementNS, sax_eventlist): Add support to
1878            normalize IDs.
1879    
1880            * test/test_xmlsupport.py
1881            (TestEventList.test_even_list_id_normalization): New test case for
1882            id normalization
1883

1902            (SaveSessionTest.testRasterLayer)
1903            (SaveSessionTest.testClassifiedLayer): Adapt to new file format.
1904            (SaveSessionTest.testLayerProjection): The filename used was the

1912            * test/runtests.py: Add CVS keywords
1913    
1914    2003-06-20  Jonathan Coles   <[email protected]>
1915    
1916            * test/test_session.py
1917            (UnreferencedTablesTests.test_unreferenced_tables_with_joins):
1918            Use the cultural_landmark-point.dbf file for the store so that
1919            the table rows and shape count match.
1920    
1921    2003-06-20  Jonathan Coles   <[email protected]>
1922    
1923            * Thuban/Model/data.py (DerivedShapeStore.__init__): Raise
1924            an exception if the number of shapes is different from the
1925            number of rows in the table. Address RTbug #1933.
1926    
1927            * test/test_layer.py (TestLayer.test_derived_store): Add
1928            a test for the new exception in DerivedShapeStore.__init__.
1929    
1930            * test/support.py (FloatTestCase): Removed since there is
1931            already FloatComparisonMixin. Fixes RTbug #1954.
1932            (FloatComparisonMixin.assertFloatEqual): Include test for
1933            infinity that was part of FloatTestCase.
1934    
1935            * test/test_range.py (RangeTest): Inherit from
1936            support.FloatComparisonMixin now that we don't have
1937            support.FloatTestCase.
1938    
1939    2003-06-20  Bernhard Herzog  <[email protected]>
1940    
1941            * test/test_save.py (SaxEventLister, sax_eventlist): Removed. Use
1942            the implementation in xmlsupport instead.
1943            (SaveSessionTest.compare_xml): sax_eventlist is now in xmlsupport
1944    
1945            * test/test_proj.py: Import sax_eventlist from xmlsupport instead
1946            of test_save
1947    
1948    2003-06-20  Bernhard Herzog  <[email protected]>
1949    
1950            * test/test_load.py (LoadSessionTest.check_format): New helper
1951            method to make sure the test files we load might have been written
1952            by the current thuban version.
1953            (ClassificationTest.TestLayers, TestSingleLayer.test)
1954            (TestLayerVisibility.test, TestClassification.test)
1955            (TestLabels.test, TestLayerProjection.test, TestRasterLayer.test):
1956            Add check_format() calls and fix the thuban data to match the data
1957            that would be written by saving the session loaded from it.
1958    
1959            * test/xmlsupport.py (SaxEventLister, sax_eventlist): Copies of
1960            the same class and function in test_save.
1961    
1962            * test/test_xmlsupport.py (TestEventList): New. test cases for
1963            sax_eventlist
1964    
1965    2003-06-20  Bernhard Herzog  <[email protected]>
1966    
1967            * Resources/XML/thuban.dtd: Add comment about which versions of
1968            Thuban are covered by this DTD
1969            (map): Fix content model for layers and raster layers. There can
1970            be any number or layers and raster layers in any order.
1971    
1972    2003-06-20  Jonathan Coles   <[email protected]>
1973    
1974            This is mainly about fixing RTbug #1949.
1975    
1976            * Thuban/Model/classification.py: Remove "from __future__"
1977            import statement since python 2.2 is the earliest supported
1978            version.
1979    
1980            * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
1981            Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES
1982            depending on the units this projection *forwards* into.
1983    
1984            * Thuban/Model/save.py (SessionSaver.write_classification):
1985            Remove unnecessary use of lambdas and nested functions.
1986    
1987            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Do scale
1988            adjustment here if the map projection uses degrees.
1989    
1990            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
1991            scale adjust code since it is now done before calling
1992            this method. Don't do anything if the map projection
1993            is None.
1994    
1995    2003-06-19  Bernhard Herzog  <[email protected]>
1996    
1997            Move version specific load tests to their own file.
1998    
1999            * test/test_load.py: Expand the doc-string to explain a bit how to
2000            handle file format changes.
2001            (TestClassification.test): Update the docstring as this test is
2002            not about Thuban 0.2 anymore.
2003    
2004            * test/test_load_0_2.py: New file with the load tests for thuban
2005            files created with Thuban 0.2 and earlier.
2006    
2007    2003-06-19  Bernhard Herzog  <[email protected]>
2008    
2009            Add XML validation to some of the tests. Validation will only be
2010            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
2011            To make the DTD available to the test cases it's moved into
2012            Resources/XML
2013    
2014            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
2015            for versions up to and including 0.2. Two slight changes: added an
2016            encoding specification and fixed the comment which refered to
2017            GRASS, not Thuban
2018    
2019            * test/xmlsupport.py: New support module for tests involving XML.
2020            Currently there's a mix-in class for XML validation.
2021    
2022            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
2023    
2024            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
2025            so that we can validate the
2026            (SaveSessionTest.testEmptySession)
2027            (SaveSessionTest.testSingleLayer)
2028            (SaveSessionTest.testSingleLayer)
2029            (SaveSessionTest.testLayerProjection)
2030            (SaveSessionTest.testRasterLayer)
2031            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
2032    
2033            * test/runtests.py (main): Call print_additional_summary instead
2034            of print_garbage_information
2035    
2036            * test/support.py (resource_dir): New function to return the
2037            "Resource" subdirectory
2038            (print_additional_summary): New function to combine several
2039            summary functions
2040            (run_tests): Use print_additional_summary instead of calling
2041            print_garbage_information directly
2042    
2043    2003-06-19  Bernhard Herzog  <[email protected]>
2044    
2045            * Doc/thuban.dtd (classification): Correct the content model of
2046            the classification element.
2047            (projection): Add the "name" attribute
2048    
2049    2003-06-19  Frank Koormann   <[email protected]>
2050    
2051            MERGE from the greater-ms3 branch.
2052    
2053            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
2054            scale if projection is latlong to get better estimate.
2055    
2056            Fix problem of hidden properties dialog under windows after double
2057            click on layer tree:
2058            The tree control always gets an Expanded / Collapsed event after
2059            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
2060            raises the already displayed window.
2061    
2062            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
2063            raiseProperties initialized to prevent endless loops
2064            (LegendTree._OnItemActivated): Depending on self.raiseProperties
2065            simply raise the properties or open the dialog and issue a second
2066            event.
2067    
2068    2003-06-18  Jonathan Coles   <[email protected]>
2069    
2070            * setup.py: Fix a few problems that occured under Windows.
2071    
2072    2003-06-18  Jonathan Coles   <[email protected]>
2073    
2074            When Thuban loaded the map was redrawn twice because the
2075            legend was being opened after the mainwindow was created
2076            and not during its creation. This meant the map was drawn
2077            initially and then had to be redrawn when the legend
2078            caused the display to change. Now the legend is opened
2079            in the mainwindow constructor which resolves this issue.
2080    
2081            Also, although we were checking for the existence of
2082            gdal and gdalwarp modules, the gdalwarp extension was
2083            still being compiled (which may fail if the system doesn't
2084            have gdal installed). the build_ext command to setup.py
2085            now accepts the flags --with-gdal and --without-gdal.
2086            If --without-gdal is specified setup.py will try to
2087            use the gdal parameters specified by gdal-config. Under
2088            windows, those parameters have to be set in setup.py
2089            as with proj4 an wxWindows.
2090    
2091            * setup.py: Use a list instead of seperate variables for
2092            extension parameters so we can create a generic function
2093            that runs an appropriate *-config script.
2094            (run_cs_script): Renamed from run_wx_script and modified
2095            to accept a second argument which is a list of lists to
2096            be filled in by the values returned from running the command.
2097            (thuban_build_ext): New. Extends the build_ext command and
2098            provides the options --with-gdal/--without-gdal which then
2099            optionally includes the gdalwarp extension.
2100    
2101            * Thuban/Model/resource.py: First check if we can import
2102            the gdalwarp Thuban extension before checking for gdal.
2103            Also added some comments.
2104            
2105            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
2106            the map is None which may be the case if none has been loaded
2107            yet.
2108    
2109            * Thuban/UI/main.py (main): Remove call to ShowLegend.
2110    
2111            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
2112    
2113            * Thuban/UI/renderer.py: Check for gdal support before importing
2114            gdalwarp.
2115            (MapRenderer.render_map): Only try to optimize if we have gdal
2116            support otherwise nothing will get drawn.
2117    
2118            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
2119            during startup before a map has been created. Check if map is None
2120            before using it and do nothing if it is.
2121    
2122    2003-06-17  Jonathan Coles   <[email protected]>
2123    
2124            Fix the problem with raster layers under Windows that caused
2125            Thuban to crash. The view should respond to layer projection
2126            changed events to update the display. Changes to a projection
2127            should not cause the map to be set to full extent.
2128            
2129            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
2130            current_map_proj to remember the current map projection so that
2131            when the projection changes we know what the previous projection
2132            was.
2133            (MapCanvas.SetMap): Unsubscribe and subscribe to
2134            LAYER_PROJECTION_CHANGED events.
2135            (MapCanvas.projection_changed): Split into two methods that respond
2136            to map and layer projection changes.
2137            (MapCanvas.map_projection_changed): New. Takes the current view and
2138            projects it using the new projection. This does not cause the
2139            map to be redrawn at full extent.
2140            (MapCanvas.layer_projection_changed): New. Cause a redraw which
2141            will draw each layer in its new projection.
2142            
2143            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
2144            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
2145            under Windows.
2146            
2147            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
2148            to twice sizeof(void*) because there are two digits for each
2149            hex byte.
2150    
2151    2003-06-16  Bernhard Herzog  <[email protected]>
2152    
2153            Update to the layer interface: Direct access to the table,
2154            shapetable, shapefile and filename attributes is now actively
2155            deprecated by issuing deprecation warnings for all places where
2156            this happens.
2157    
2158            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
2159            to the instance variables table, shapetable, shapefile and
2160            filename via __getattr__ so that we can issue a deprecation
2161            warning.
2162            (Layer.SetShapeStore): Don't set the deprecated instance variables
2163            any more
2164            (Layer.SetShapeStore): Don't use deprecated layer instance
2165            variables
2166            (Layer.Destroy): No need to explicitly remove the instance
2167            variables any more
2168            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
2169            instance variables
2170    
2171            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
2172            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
2173            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
2174            use deprecated layer instance variables
2175    
2176            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
2177            deprecated layer instance variables
2178    
2179            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
2180            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
2181            instance variables
2182    
2183            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
2184            deprecated layer instance variables
2185    
2186            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
2187            deprecated layer instance variables
2188    
2189            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
2190            deprecated layer instance variables
2191    
2192            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
2193            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
2194            variables
2195    
2196            * test/runtests.py (main): Turn Thuban's deprecation warnings into
2197            errors so that they're cought by the tests
2198    
2199            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
2200            layer instance variables
2201    
2202    2003-06-16  Jonathan Coles   <[email protected]>
2203    
2204            Fix a problem under Windows whereby if the user double-clicks on a
2205            layer in the legend that tree item will expand or collapse as well
2206            as open the layer properties dialog. The state of the tree item
2207            should not be affected.
2208    
2209            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
2210            preventExpandCollapse and subscribe to expanding and collapsing
2211            events.
2212            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
2213            collapsing events and will veto the event if it has been triggered
2214            by the user double clicking on a layer.
2215            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
2216            that an expanding/collapsing event should be vetoed.
2217    
2218    2003-06-13  Bernhard Herzog  <[email protected]>
2219    
2220            * Thuban/UI/classifier.py (Classifier.OnClose)
2221            (Classifier.map_layers_removed)
2222            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
2223            in OnClose and not in map_layers_removed or
2224            layer_shapestore_replaced to make sure it always happens when the
2225            dialog is closed
2226    
2227    2003-06-13  Jonathan Coles   <[email protected]>
2228    
2229            This puts back a fix for Windows where a panel is needed so that
2230            the background of the table view appears correctly.
2231    
2232            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
2233            object that can be used by derived classes to place any
2234            controls (including the grid) onto.
2235            (QueryTableFrame.__init__): Use the panel as the parent window
2236            for all the controls. Reparent the grid so that the panel is
2237            the parent. Call UpdateStatusText() to correctly initialize
2238            the status bar.
2239    
2240    2003-06-13  Jonathan Coles   <[email protected]>
2241    
2242            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
2243            from wxFrame (as opposed to wxDialog like the other classes)
2244            but otherwise behaves like the other classes. This is needed
2245            for the TableView which isn't really a dialog and needs to
2246            have a status bar and control buttons.
2247    
2248            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
2249            instance variable to keep track of how many rows are selected.
2250            Subscribe once to the the events we are interested in.
2251            (ThubanGrid.OnRangeSelect): Only handle event if event handling
2252            hasn't been turned off.
2253            (ThubanGrid.OnSelectCell): Only handle event if event handling
2254            hasn't been turned off.
2255            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
2256            as an event listener (which changes the event handler stack)
2257            simply set an instance variable to False. This is checked in
2258            the event handlers.
2259            (ThubanGrid.GetNumberSelected): Return the number of currently
2260            selected rows.
2261            (TableFrame): Inherit from ThubanFrame so we can have a
2262            status bar and control buttons.
2263            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
2264            Explicitly set which items are selected in the operator choice and
2265            action choice so there is always a valid selection. Fixes RTbug #1941.
2266            Subscribe to grid cell selection events so we can update the
2267            status bar.
2268            (QueryTableFrame.UpdateStatusText): Update the status bar with
2269            how many rows are in the grid, how many columns, and how many
2270            rows are selected.
2271            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
2272            Call UpdateStatusText when cells are (de)selected.
2273            (QueryTableFrame.OnQuery): Use the string value in the value
2274            combo if either the selected item index is 0 or if the string
2275            cannot be found in the predefined list (this happens if the
2276            user changes the text). Fixes RTbug #1940.
2277            Only turn off the grid event listeners if there a query comes
2278            back with a none empty list of ids. in the case that the list
2279            is empty this causes a grid.ClearSelection() call to actually
2280            clear the grid selection which causes the selected items in
2281            the map to be deselected. Fixes RTbug #1939.
2282    
2283            * test/test_save.py (XMLWriterTest.Encode): Check return values.
2284            Fixes RTbug #1851.

2287    
2288            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
2289            self.selected_shape with the current selection to make sure the
2290            contents of the dialog are up to date when it's shown for the
2291            first time.
2292            The dialog used to work without this by luck. The recent fix to
2293            the connector module 'broke' a 'feature' the identify view was
2294            relying on, i.e that subscribing to a message in response to
2295            receiving a message of that type would mean that the new
2296            subscriber would also be called for the same message.
2297            
2298    2003-06-12  Jonathan Coles   <[email protected]>
2299    
2300            * extensions/thuban/gdalwarp.cpp: Removed debug printing as

2305            * Thuban/Lib/fileutil.py: As is done under Windows, create the
2306            user directory if it doesn't exist on a posix system.
2307            Fixes RTbug #1815.
2308    
2309            * Thuban/Model/resource.py (get_user_proj_files): Moved the
2310            called to get_application_dir here, so that the directory
2311            will only be called if this method is invoked.
2312    
2313            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
2314            the projfilepath if no projection is selected.
2315    
2316    2003-06-12  Jonathan Coles   <[email protected]>

2318            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
2319            the scalebar if the current map has no projection set.

2322            projfilepath label to just the basename of the projection file
2323            rather than include the entire path.
2324    
2325            * Thuban/Model/resource.py: Fix missed proj functions that
2326            needed to be renamed.
2327

2329    
2330            * Thuban/Model/classification.py: Removed assert statements that
2331            tested if the variable was an instance of Color.
2332    
2333            * Thuban/Model/color.py (Color): Remove commented code that isn't
2334            used.
2335            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
2336            Fixes RTbug #1835.
2337            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
2338            Needed now that the class doesn't inherit from Color.
2339    
2340    2003-06-12  Jonathan Coles   <[email protected]>
2341

2355    2003-06-12  Jonathan Coles   <[email protected]>
2356    
2357            This is largely a collection of bug fixes. We also handle the
2358            case where gdal is not on the system. The XMLReader and XMLWriter
2359            classes were moved into there own files to resolve some circular
2360            import references and because they shouldn't really be in the
2361            file that is dediciated to reading/writing session files since
2362            they are also used elsewhere.
2363    
2364            * Thuban/Model/classgen.py: Renamed functions to follow the
2365            function_names_with_underscores style. Fixes RTbug #1903.

2415            * Thuban/UI/projdialog.py: Use renamed projection resource functions.
2416    
2417            * Thuban/UI/renderer.py (MapRenderer.render_map): Only try to
2418            optimize if a raster layer is visible. Fixes RTbug #1931.
2419            Only draw the raster layer if the gdal library is available.
2420            Addresses RTbug #1877.
2421    
2422            * test/test_classgen.py: Add tests for generate_singletons,
2423            generate_uniform_distribution, generate_quantiles. Fixes RTbug #1903.
2424            (test_calculate_quantiles): Fix some tests to catch the new

2438    
2439            * Thuban/UI/mainwindow.py: import wxMultipleChoiceDialog from

2465            dialog is showing is removed.
2466    
2467    2003-06-10  Bernhard Herzog  <[email protected]>
2468    
2469            * Thuban/Lib/connector.py (Connector.Issue): Iterate over a copy

2485            LAYER_CHANGED will still be sent if the classification changes.
2486    
2487            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
2488            parameter so we can subscribe to some of its messages
2489            (Classifier.__init__): Subscribe to the map's MAP_LAYERS_REMOVED
2490            and the layer's LAYER_SHAPESTORE_REPLACED
2491            (Classifier.unsubscribe_messages): New. Unsubscribe from message
2492            subscribed to in __init__
2493            (Classifier.map_layers_removed)
2494            (Classifier.layer_shapestore_replaced): receivers for the messages

2511            (SetShapeStoreTests.test_set_shape_store_same_field_different_type):
2512            Add tests for the messages. This checks both the new
2513            LAYER_SHAPESTORE_REPLACED and the older LAYER_CHANGED
2514    
2515    2003-06-06  Jan-Oliver Wagner <[email protected]>

2521    
2522            * Thuban/UI/identifyview.py (IdentifyView.__init__):

2524            in the dialog.
2525    
2526    2003-06-05  Frank Koormann  <[email protected]>
2527    
2528            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
2529            once on initialisation (Former implementation resulted in multiple
2530            entries for each projection).
2531            (ProjFrame.__FillAvailList): selectProj as second optional parameter,
2532            if set, select the projection found under the specified name. This
2533            overwrites any other selection estimate.
2534            Removed projchoice filling from this method.
2535            (ProjFrame._OnSave, ProjFrame._OnAddToList):
2536            Updated call of ProjFrame.__FillAvailList

2554    
2555            Do not cache the values returned by the tree widget's
2556            GetFirstChild and GetNextChild methods because it led to lots of
2557            segfaults. The new way requires more brute force but is more
2558            reliable.
2559    
2560            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
2561            variable layer2id
2562            (LegendTree.find_layer): New method to do with brute force what
2563            layer2id tried to accomplish
2564            (LegendTree._OnMsgLayerChanged)
2565            (LegendTree._OnMsgLayerTitleChanged, LegendTree.__ShowHideLayer):
2566            Use find_layer instead of layer2id
2567            (LegendTree.__RemoveLayer, LegendTree.__AddLayer): No need to
2568            update layer2id anymore
2569            (LegendTree._OnMsgMapLayersRemoved)
2570            (LegendTree._OnMsgMapLayersAdded): Get by without layer2id.

2590            whether the modified flag is set properly
2591    
2592            * Thuban/Model/base.py (TitledObject.SetTitle): Call changed
2593            instead of issue so that the modified flags get updated.
2594    
2595            * test/test_base.py (SomeTitledObject): Derive from Modifiable
2596            instead of Publisher to reflect reality better and to accomodate
2597            the fact that SetTitle now calls changed instead of issue
2598    
2599    2003-06-02  Bernhard Herzog  <[email protected]>
2600    
2601            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource
2602            acquisition has to happen before the try in a try-finally.
2603    
2604    2003-06-02  Bernhard Herzog  <[email protected]>
2605    
2606            * Thuban/UI/legend.py (LegendTree._OnMsgMapLayersRemoved): It's
2607            possible that a layer is removed that is not currently selected in
2608            the legend so don't check for this.
2609    
2610    2003-05-30  Bernhard Herzog  <[email protected]>
2611    
2612            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
2613            variables to None that have direct or indirect references to
2614            shapefiles or dbf files to make sure that they do go away and the
2615            files are closed.
2616    
2617    2003-05-30  Bernhard Herzog  <[email protected]>
2618    
2619            * Thuban/UI/legend.py (LegendTree.GetRootItem): Reset

2623    
2624            * Thuban/UI/legend.py (LegendTree.__init__): New instance variable
2625            changing_selection to indicate whether the LegendTree code itself
2626            is currently changing the selection
2627            (LegendTree.normalize_selection): New method to normalize the
2628            selection by selecting the layer item even if the user clicked on
2629            the classification.
2630            (LegendTree._OnSelChanged): normalize the selection. This works
2631            around a bug in wx which doesn't keep track of the selection
2632            properly when subtrees are deleted.
2633    
2634    2003-05-30  Bernhard Herzog  <[email protected]>

2647            * Thuban/Model/map.py (Map.TopLayer, Map.BottomLayer): Renamed
2648            to MoveLayerToTop and MoveLayerToBottom respectively. Fixes
2649            RTBug #1907.
2650    
2651            * Thuban/UI/classgen.py: Use classgen functions that were part
2652            of the ClassGenerator class. Put try/finally blocks around
2653            code that uses wxBeginBusyCursor()/wxEndBusyCursor(). Fixes
2654            RTBug #1904.
2655    
2656            * Thuban/UI/classifier.py: Remove unused import of ClassGenerator.
2657    
2658            * Thuban/UI/legend.py: The legend was cleared and repopulated any
2659            time something changed which caused some state to be lost such

3036            "LEFT OUTER JOIN" instead of "JOIN", which preserves all records of
3037            the left table. Records not matching are filled with 0 / None.
3038    
3039            * Thuban/UI/join.py (JoinDialog.__init__): Checkbox for outer join.
3040            (JoinDialog.OnJoin): Consider outer join check box.
3041    
3042    2003-05-22  Bernhard Herzog  <[email protected]>
3043    
3044            * Thuban/UI/join.py (JoinDialog.OnJoin): Use exc_info in a
3045            somewhat safer way. Storing the traceback in a local variable can
3046            lead to memory leaks
3047    
3048    2003-05-22  Bernhard Herzog  <[email protected]>
3049    
3050            * Thuban/UI/join.py (JoinDialog.OnJoin): Make sure to really call

3052    
3053    2003-05-22  Frank Koormann  <[email protected]>
3054    
3055            * Thuban/UI/join.py (JoinDialog.__init__): Make use of
3056            TransientTable.Title()

3059    
3060            Join Dialog, initial version.
3061    
3062            * Thuban/UI/mainwindow.py (MainWindow.TableJoin): Removed print.
3063    
3064            * Thuban/UI/join.py (JoinDialog): Functional implementation of
3065            former framework. Renamed Table1/Table2 to LeftTable/RightTable
3066            in all occurences.
3067    
3068            * Thuban/Model/transientdb.py (TransientJoinedTable.__doc__):

3070    
3071    2003-05-22  Bernhard Herzog  <[email protected]>
3072    
3073            Give the tables titles so that the GUI can display more meaningful
3074            names. For now the titles are fixed but depend on e.g. filenames
3075            or the titles of the joined tables.
3076    
3077            * Thuban/Model/transientdb.py (TransientTable.Title)
3078            (TransientJoinedTable.Title, AutoTransientTable.Title): New.
3079    
3080            * Thuban/Model/table.py (DBFTable.Title, MemoryTable.Title): New.
3081    
3082            * test/test_transientdb.py
3083            (TestTransientTable.test_auto_transient_table_title): New. Test
3084            for the Title method

3096    
3097            * test/test_layer.py (TestLayer.setUp, TestLayer.tearDown):
3098            Provide a better way to destroy the layers

3143            remove tables
3144    
3145            * test/test_session.py (TestSessionSimple.test_remove_table): New.
3146            Test for RemoveTable
3147    
3148    2003-05-22  Thomas Koester  <[email protected]>
3149    
3150            * Thuban/Model/classgen.py: Added short module doc string and CVS id.
3151            (ClassGenerator.GenUniformDistribution): Use new Range __init__, too.
3152    
3153    2003-05-22  Bernhard Herzog  <[email protected]>
3154    
3155            Implement a way to discover dependencies between tables and
3156            shapestores.
3157    
3158            * Thuban/Model/transientdb.py (TransientTableBase.Dependencies)
3159            (TransientJoinedTable.Dependencies)

3174            (ShapefileStore.FileName, ShapefileStore.FileType): New. Accessor
3175            methods for filename and type
3176            (ShapefileStore.Dependencies): New. Implement the dependencies
3177            interface
3178            (DerivedShapeStore): New class to replace SimpleStore. The main
3179            difference to SimpleStore is that it depends not on a shapefile
3180            but another shapestore which expresses the dependencies a bit
3181            better
3182            (SimpleStore.__init__): Add deprecation warning.

3192            Test for the Dependencies method.
3193            (TestTransientTable.test_transient_joined_table): Add test for the
3194            Dependencies method.
3195    
3196            * test/test_session.py (TestSessionSimple.setUp)
3197            (TestSessionSimple.tearDown): New. Implement a better way to
3198            destroy the sessions.
3199            (TestSessionSimple.test_initial_state)
3200            (TestSessionSimple.test_add_table): Bind session to self.session
3201            so that it's destroyed by tearDown
3202            (TestSessionSimple.test_open_shapefile): New. Test for
3203            OpenShapefile and the object it returns
3204    
3205    2003-05-22  Bernhard Herzog  <[email protected]>
3206    
3207            * Thuban/Model/session.py (Session.AddTable): New method to
3208            register tables with the session.
3209            (Session.Tables): Return the tables registered with AddTable too.
3210    
3211            * test/test_session.py (TestSessionSimple.test_add_table): New.
3212            Test case for the AddTable method
3213    
3214    2003-05-22  Frank Koormann  <[email protected]>
3215    
3216            UI polishing updates: Place main buttons (OK, Cancel, etc) in the
3217            lower right corner, center labels for selections, initialize controls
3218            in reasonable order for keyboard navigation.
3219    
3220            * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
3221            (ProjFrame.__DoOnProjAvail): Determine position of current projection
3222            using the wxListBox.FindString() method. Still a problem (#1886)
3223    
3224            * Thuban/UI/classifier.py
3225            (Classifier.__init__, SelectPropertiesDialog.__init__)
3226    
3227            * Thuban/UI/classgen.py (ClassGenDialog.__init__,
3228            (ClassGenDialog.__DoOnGenTypeSelect): Moved initialization of the
3229            different classification types from here to __init__.
3230            (GenUniquePanel.__init__): Set the column width of the first field
3231            in the Field ListCtrl to the full width.
3232    
3233            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Rename 'Save As'
3234            Button to 'Export'. Center Buttons in Selection Box, set Focus to
3235            Grid.
3236            (LayerTableFrame.OnKeyDown()): New, bound to the grid with EVT_KEY_DOWN,
3237            changes focus to the Selection when pressing "Alt-S".
3238    
3239            * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
3240            the text if not visible. The italic font sometimes exceeds the
3241            rendering area.
3242    
3243    2003-05-21  Jonathan Coles   <[email protected]>
3244    
3245            * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
3246            to OnClose so that Thuban closes correctly.
3247    
3248            * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
3249            DockFrame.OnClose, not DockFrame._OnClose.
3250    
3251    2003-05-21  Jonathan Coles   <[email protected]>
3252    
3253            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
3254            references to 'inf' and use new Range __init__ to pass floats
3255            directly rather than converting them to strings first.
3256            Fixes RTBug #1876.
3257    
3258            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
3259            Use new Range ___init__ to pass floats.
3260    
3261            * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
3262            filename is a valid image file. Throw IOError otherwise.
3263

3265            is immutable and has an __init__ which can accept floats.
3266    
3267            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
3268            into try block. AddLayer doesn't throw any exceptions anymore.
3269            (MainWindow.AddRasterLayer): Move constructor of RasterLayer into
3270            try block.
3271    
3272            * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as
3273            the first item in choices. Fixes RTBug #1882.
3274    
3275            * Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale
3276            has gone to 0 which is a serious problem. abort.
3277            (MapRenderer.draw_raster_layer): Catch IOError seperately and
3278            print the error from GDAL.
3279    
3280            * Thuban/UI/tableview.py (TableGrid.__init__): Call
3281            ToggleEventListeners to turn on listening.
3282            (TableGrid.ToggleEventListeners): New. Turns event listening on
3283            and off so as to prevent excessive messages.
3284            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
3285            to suppress excessive messages when selecting many rows.
3286            Fixes RTBug #1880.
3287    
3288            * Thuban/UI/view.py: Added checks against if scale == 0. This
3289            is a serious problem that can occur when an image without
3290            geo data is loading and causes the map projection bounds to
3291            go to infinity. Right now, the solution is to simply try
3292            to recover.
3293    
3294            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
3295            to set the MFILEReceiver attributes even if the data is NULL.
3296    
3297            * extensions/thuban/gdalwarp.cpp: Improved the error handling
3298            and passed GDAL messages back up to the Python layer. Also
3299            tried to fix some memory leaks that were present in the original
3300            utility but didn't matter because the program aborted.
3301    
3302            * test/test_range.py: Copied over tests from SciParam. Removed
3303            tests against importing. Fixes RTBug #1867.
3304    
3305    2003-05-21  Bernhard Herzog  <[email protected]>
3306    
3307            * test/test_load.py: Remove unused imports and restructure the
3308            test code
3309            (LoadSessionTest): Split into one class for each test and turn
3310            LoadSessionTest itself into the base class for all such session
3311            tests.
3312            (ClassificationTest): New base class for load tests that test
3313            classifications
3314            (TestSingleLayer, TestLayerVisibility, TestClassification)
3315            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
3316            for the individual tests
3317    
3318            * test/support.py (FileLoadTestCase.filename): New base class for
3319            file loading tests
3320    
3321    2003-05-21  Jan-Oliver Wagner <[email protected]>
3322    
3323            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
3324            Mercator' to 'UTM Zone 32' as a more convenient example.
3325            Added 'Gauss Krueger Zone 6'.
3326    
3327            * Data/iceland_sample_raster.thuban: political polygon now
3328            filled transparent to have the raster image visible at once.
3329    
3330    2003-05-21  Frank Koormann  <[email protected]>
3331    
3332            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
3333            OnClose() to keep in sync with extensions. Internally Thuban
3334            still uses "underscored" names.
3335    
3336    2003-05-20  Jonathan Coles   <[email protected]>
3337    
3338            This puts back Raster layer support. These layers support projections
3339            through the GDAL library. Currently, the CVS version is being used.
3340            There are no Debian packages available although this may change soon.
3341            A GDAL driver was extended to support writing to memory rather to
3342            files.
3343    
3344            There is still some work that needs to be done, such as some error
3345            handling when loading invalid images or when there is a problem
3346            projecting the image. This putback simply checks in the majority
3347            of the work.
3348    
3349            * setup.py: Add gdalwarp library extension.
3350    
3351            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
3352            Defaults to False, but can be overridden by subclasses if they
3353            support classification.
3354            (RasterLayer): New. Defines a new layer that represents an
3355            image.
3356    
3357            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
3358            tag handler.
3359            (SessionLoader.start_layer): Encode the filename.
3360            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
3361            New. Supports reading a rasterlayer tag.

3364    
3365            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
3366            get a string in Latin1. If we get such as string convert it to
3367            unicode first, otherwise leave if alone before encoding.
3368            (SessionSaver.write_layer): Add support for writing both Layers
3369            and RasterLayers.
3370    
3371            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
3372            The right argument may not be a string, it could also be a Column.
3373    
3374            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
3375            Make initial window size 600x400. Fixes RTBug #1872.
3376    
3377            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
3378            the dialog is constructed so that we can support layers that
3379            do not have classifications.
3380            (Classifier._OnTry): Only build a classification if the layer
3381            supports one.
3382    
3383            * Thuban/UI/legend.py: Change all checks that a layer is an
3384            instance of Layer into checks against BaseLayer.
3385            (LegendTree.__FillTreeLayer): Only add children to a branch if
3386            the layer supports classification.
3387    
3388            * Thuban/UI/mainwindow.py (MainWindow.NewSession,
3389            MainWindow.OpenSession): Don't proceed with an action if the
3390            user chooses Cancel when they are asked to save changes.
3391            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
3392            user to select an image file. Create a new RasterLayer and add
3393            it to the map.
3394    
3395            * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
3396            for rendering RasterLayer layers.
3397            (MapRenderer.draw_raster_layer): Actually method that calls
3398            the GDALWarp python wrapper and constructs an image from the
3399            data returned.
3400    
3401            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the
3402            Choices symbols to match those used in the table query method.
3403            Replace deprecated method calls on table with new method names.
3404    
3405            * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
3406            how small the scale can get. This still needs more testing.
3407    
3408            * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
3409            Provides a driver to output in .bmp format.
3410    
3411            * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h:
3412            New. Provides IO routines which write to memory, rather than a file.

3577            (ClassGroupRange): Use the Range class to store the underlying
3578            range information. The interface remains the same, except for
3579            GetRange(), and you can also supply a Range object as the min

3626            * Thuban/UI/tableview.py (TableGrid.OnRangeSelect): Fix some issues
3627            with correctly selecting the rows and issuing the right events.
3628            Be sure to call Skip() to allow the grid to do some of its own
3629            handling which allows the rows to actually be selected.
3630            (LayerTableGrid.select_shapes): Rename from select_shape. Supports
3631            selecting multiple shapes.
3632            (LayerTableFrame): Support for building Queries.

3772            Convert all table users to use the new table interface. This only
3773            covers Thuban itself, not GREAT-ER or other applications built on

3789            * test/test_transientdb.py
3790            (TestTransientTable.run_iceland_political_tests): Use the
3791            constants for the types. Add a test for HasColumn

3837            Addresses the "Selection Extent" wish of RTbug #1787.
3838    
3839            * Resources/Bitmaps/fulllayerextent.xpm,
3840            Resources/Bitmaps/fullselextent.xpm: Bitmaps for layer and selection
3841            extent. These are just place holders for the real bitmaps.
3842    
3843            * Thuban/Model/layer.py (Shape): Since a Shape is immutable only
3844            calculate the bounding box once (the first time compute_bbox() is
3845            called).
3846            (Layer.ShapesBoundingBox): New. Given a list of shape ids, return
3847            the bounding box for the shapes in lat/long coordinates.
3848    
3849            * Thuban/UI/mainwindow.py: Added new "Full selection extent" menu
3850            option.

3864            shapes on the canvas using the map projection (if any).
3865    
3866            * test/test_layer.py (TestLayer.test_arc_layer): Add some tests
3867            for Layer.ShapesBoundingBox().

3875            Addresses the "Full Layer Extent" wish of RTbug #1787.
3876    
3877            * Resources/Projections/defaults.proj: Added UK National Grid.
3878    
3879            * Thuban/UI/mainwindow.py: Added new "Full layer extent" menu option.

3888            Convert the table implementations to a new table interface. All
3889            tables use a common mixin class to provide backwards compatibility
3890            until all table users have been updated.
3891    
3892            * Thuban/Model/table.py (OldTableInterfaceMixin): Mixin class to
3893            provide backwards compatibility for table classes implementing the
3894            new interface
3895            (DBFTable, MemoryTable): Implement the new table interface. Use
3896            OldTableInterfaceMixin as base for compatibility
3897            (DBFColumn, MemoryColumn): New. Column description for DBFTable
3898            and MemoryTable resp.
3899    
3900            * test/test_dbf_table.py: New. Test cases for the DBFTable with
3901            the new table interface.
3902    
3903            * test/test_memory_table.py: New. Test cases for the MemoryTable
3904            with the new table interface.
3905    
3906            * test/test_table.py: Document the all tests in this file as only
3907            for backwards compatibility. The equivalent tests for the new
3908            interface are in test_memory_table.py and test_dbf_table.py
3909            (MemoryTableTest.test_read): field_info should be returning tuples
3910            with four items
3911            (MemoryTableTest.test_write): Make doc-string a more precise.
3912    
3913            * Thuban/Model/transientdb.py (TransientTableBase): Convert to new
3914            table interface. Derive from from OldTableInterfaceMixin for
3915            compatibility.
3916            (TransientTableBase.create): New intance variable column_map to
3917            map from names and indices to column objects
3918            (TransientTable.create): Use the new table interface of the input
3919            table
3920            (AutoTransientTable): Convert to new table interface. Derive from
3921            from OldTableInterfaceMixin for compatibility.
3922            (AutoTransientTable.write_record): Removed. It's not implemented
3923            yet and we still have to decide how to handle writing with the new
3924            table and data framework.
3925    
3926            * test/test_transientdb.py
3927            (TestTransientTable.run_iceland_political_tests)
3928            (TestTransientTable.test_transient_joined_table): Use the new
3929            table interface

3932    
3933            This is namely a collection of UI updates to improve user interactivity.
3934            Tabbing between controls now exists and you can use ESC to close dialog
3935            boxes; ENTER will active the default button.
3936    
3937            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Rearrange the
3938            order that the controls are created so that tabbing works correctly.
3939            (ClassGenDialog.OnOK): Renamed from _OnGenerate() so that the
3940            wxDialog can handle the default button correctly.
3941            (ClassGenDialog.OnCancel): Renamed from _OnCloseBtn() for the
3942            same reasons as for OnOK.
3943            (GenUniformPanel._OnRetrieve): Call wxBeginBusyCursor/wxEndBusyCursor
3944            when we ask the table for the maximum/minimum values of a field
3945            which could take a very long time.
3946    
3947            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange the
3948            order that the controls are created so that tabbing works correctly.
3949            (SelectPropertiesDialog.__init__): Rearrange the order that the
3950            controls are created so that tabbing works correctly.
3951    
3952            * Thuban/UI/dialogs.py: Copied NonModalDialog box and changed it
3953            to derive from a wxDialog but behave like the original implementation
3954            which was derived from a wxFrame. wxDialog provides useful key
3955            handling functionality like ESC calling OnCancel and ENTER calling
3956            OnOK which is lost with wxFrame.
3957    
3958            * Thuban/UI/mainwindow.py: Add "..." to menu items that will open
3959            new dialogs.
3960    
3961            * Thuban/UI/projdialog.py (ProjFrame.__init__): Rearrange the
3962            order that the controls are created so that tabbing works correctly.
3963            (ProjFrame.OnApply): Renamed from _OnTry() to use wxDialog behaviour.
3964            (ProjFrame.OnOK): Renamed from _OnOK() to use wxDialog behaviour.
3965            (ProjFrame.OnCancel): Renamed from _OnClose() to use wxDialog behaviour.
3966            (ProjPanel.__init__): Add "Airy" to the list of ellipsoids so we
3967            can provide the "UK National Grid" as a default projection.
3968            (UTMPanel.__init__): Rearrange the order that the controls are
3969            created so that tabbing works correctly.
3970    
3971    2003-05-05  Bernhard Herzog  <[email protected]>
3972    
3973            * extensions/thuban/wxproj.cpp: Fix some of the comments.
3974            (project_point): If a map projection but no layer projection is
3975            given, convert degrees to radians before applying the map
3976            projection.
3977    
3978            * Thuban/UI/tableview.py (TableGrid.disallow_messages)
3979            (TableGrid.allow_messages): New methods to make it possible to
3980            inhibit message sending.
3981            (TableGrid.issue): Only send the message if not inhibited.
3982            (LayerTableGrid.select_shape): Use the new methods to make sure
3983            that no ROW_SELECTED message is sent while we're updating the
3984            selected rows to match the selected shapes.
3985

3987    
3988            Implementation of MemoryTable.
3989    
3990            * Thuban/Model/table.py (MemoryTable): New. Quite simple table
3991            implementation that operates on a list of tuples. All of the data
3992            are kept in the memory.
3993    
3994            * test/test_table.py (MemoryTableTest): New.
3995    
3996            * test/test_transientdb.py (SimpleTable): Removed.
3997            (TestTransientTable.test_transient_joined_table,
3998            (TestTransientTable.test_transient_table_read_twice): Replaced
3999            SimpleTable by MemoryTable.
4000    
4001    2003-04-30  Jonathan Coles   <[email protected]>
4002    
4003            * Data/iceland_sample.thuban: Now contains correct projections
4004            for each of the layers.
4005    
4006            * Resources/Projections/defaults.proj: Geographic projection
4007            contains unit conversion parameter.
4008    
4009    2003-04-30  Jonathan Coles   <[email protected]>
4010    
4011            The most important part of this putback is the projection changes.
4012            It should now be possible to specify the projection that a layer
4013            is in and then specify a different projection for the map. The
4014            projection dialog has an extra parameter for a geographic projection
4015            which lets the user select if the input is in degrees or radians.
4016    
4017            * Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring
4018            to say that the parameter is a tuple of unprojected
4019            points (which is what the callers to this method were assuming).
4020            Also, since the points are unprojected we need to projected them.
4021    
4022            * Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp,
4023            LegendTree.MoveCurrentItemDown): If the layer or any of the layer's
4024            groups are selected, move the layer up/down. Fixes RTbug #1833.
4025    
4026            * Thuban/UI/mainwindow.py: Move menu item map_rename up.
4027    
4028            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing
4029            parameter in call to SetClientData.
4030            (GeoPanel): Add support for selecting the units that the
4031            source data is in (Radians or Degrees).
4032    
4033            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize
4034            the rendering loop by reducing the number of if's, removing the
4035            unnecessary try/except block, and checking if the old group
4036            is the same as the new one (which happens a lot if there is
4037            no classification, or lots of shapes are in the same group).
4038    
4039            * Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block
4040            around the redraw routine to try to catch problems that the user
4041            may create by selecting invalid projections for the data set and
4042            map. Clears the display if there are any problems and prints the
4043            error.
4044            (MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled
4045            rectangle.
4046    
4047            * extensions/thuban/wxproj.cpp (project_point): First invert the
4048            supplied point (which should be in projected coordinates) using
4049            the layer's projection and then project the point using the
4050            map's projection.
4051            (project_points): Use project_point() to project each point.
4052    
4053    2003-04-30  Jan-Oliver Wagner <[email protected]>
4054    
4055            * Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug:
4056            don't set the Classification to None if the classfication field
4057            is None (ie only a DEFAULT).
4058    
4059    2003-04-30  Bernhard Herzog  <[email protected]>
4060    
4061            * Thuban/UI/view.py: Fix some typos.
4062    
4063            * Thuban/UI/mainwindow.py (MainWindow.identify_view_on_demand): Do
4064            not pop up the dialog if the selection becomes empty (this could
4065            happen if e.g. a new selection is opened while the identify tool
4066            is active and dialog had been closed)
4067    
4068    2003-04-30  Bernhard Herzog  <[email protected]>
4069    
4070            * Thuban/Model/transientdb.py (TransientTableBase.__init__): New
4071            instance variable read_record_last_result
4072            (TransientTableBase.read_record): Make sure reading the same
4073            record twice works. The implementation uses the new instance
4074            variable read_record_last_result
4075    
4076            * test/test_transientdb.py
4077            (TestTransientTable.test_transient_table_read_twice): New test
4078            case for the above bug-fix.
4079    
4080    2003-04-29  Jonathan Coles   <[email protected]>
4081    
4082            * Thuban/common.py: Removed. No longer needed Str2Num. RTbug #1832.
4083    
4084            * Thuban/UI/classgen.py: Remove all uses of Str2Num.
4085    
4086            * Thuban/UI/classifier.py: Remove all uses of Str2Num.
4087            (ClassTable.SetValueAsCustom): Rename keyword argument in
4088            ClassGroup* constructors to match argument name.
4089    
4090    2003-04-29  Bernhard Herzog  <[email protected]>
4091    
4092            * Thuban/Model/session.py (Session.Destroy): Explicitly close the
4093            transient DB if it exists to make sure it doesn't leave a journal
4094            file in the temp directory.
4095    
4096            * Thuban/Model/transientdb.py (TransientDatabase.close): Set
4097            self.conn to None after closing the connection to make sure it's
4098            not closed twice
4099    
4100    2003-04-29  Jonathan Coles   <[email protected]>
4101    
4102            Add a visible parameter in the layer XML tag. The default value is
4103            "true". If anything other than "false" is specified we also assume
4104            "true". Addresses RTbug #1025.
4105    
4106            * Doc/thuban.dtd: Add visible parameter to a layer.
4107    
4108            * Thuban/Model/layer.py (BaseLayer.__init__): Change default value
4109            of visible from 1 to True.
4110            (Layer.__init__): Change default value of visible from 1 to True.
4111    
4112            * Thuban/Model/load.py (SessionLoader.start_layer): Read visible
4113            parameter.

4120            (LoadSessionTest.testLayerVisibility): Test if the visible flag
4121            is loaded correctly.
4122    
4123            * test/test_save.py (SaveSessionTest.testSingleLayer): Add test
4124            for saving an invisible layer.
4125    
4126    2003-04-29  Jonathan Coles   <[email protected]>
4127    
4128            * Thuban/UI/mainwindow.py (MainWindow.SetMap): Look up the
4129            legend dialog box and tell it to change its map to the one
4130            supplied to SetMap(). Fixes RTbug #1770.
4131    
4132    2003-04-29  Bernhard Herzog  <[email protected]>
4133    
4134            Next step of table implementation. Introduce a transient database
4135            using SQLite that some of the data is copied to on demand. This
4136            allows us to do joins and other operations that require an index
4137            for good performance with reasonable efficiency. Thuban now needs
4138            SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I
4139            haven't tested that.
4140            
4141            * Thuban/Model/transientdb.py: New. Transient database
4142            implementation.
4143    
4144            * test/test_transientdb.py: New. Tests for the transient DB
4145            classes.
4146    
4147            * Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New
4148            classes to help automatically remove temporary files and
4149            directories.
4150            (Session.__init__): New instance variables temp_dir for the
4151            temporary directory and transient_db for the SQLite database
4152            (Session.temp_directory): New. Create a temporary directory if not
4153            yet done and return its name. Use AutoRemoveDir to have it
4154            automatically deleted
4155            (Session.TransientDB): Instantiate the transient database if not
4156            done yet and return it.
4157    
4158            * Thuban/Model/data.py (ShapefileStore.__init__): Use an
4159            AutoTransientTable so that data is copied to the transient DB on
4160            demand.
4161            (SimpleStore): New class that simply combines a table and a
4162            shapefile
4163    
4164            * Thuban/Model/table.py (Table, DBFTable): Rename Table into
4165            DBFTable and update its doc-string to reflect the fact that this
4166            is only the table interface to a DBF file. Table is now an alias
4167            for DBFTable for temporary backwards compatibility.
4168    
4169            * Thuban/UI/application.py (ThubanApplication.OnExit): Make sure
4170            the last reference to the session goes away so that the temporary
4171            files are removed properly.
4172    
4173            * test/test_load.py (LoadSessionTest.tearDown): Remove the
4174            reference to the session to make sure the temporary files are
4175            removed.
4176    
4177    2003-04-29  Bernhard Herzog  <[email protected]>
4178    
4179            * Thuban/Model/load.py (XMLReader.__init__, XMLReader.read): Turn
4180            the __parser instance variable into a normal local variable in
4181            read. It's only used there and read will never be called more than
4182            once. Plus it introduces a reference cycle that keeps can keep the
4183            session object alive for a long time.
4184    
4185    2003-04-29  Jonathan Coles   <[email protected]>
4186    
4187            * Thuban/Model/proj.py (Projection): Removed Set*() methods to make
4188            Projection an immutable item. Fixes RTbug #1825.
4189            (Projection.__init__): Initialize instance variables here.
4190            (ProjFile.Replace): New. Replace the given projection object with
4191            the new projection object. This solves the problem of needing the
4192            mutator Projection.SetProjection() in the ProjFrame class and
4193            allows a projection to change parameters without changing its
4194            location in the file.
4195    
4196            * Thuban/UI/mainwindow.py (MainWindow.SaveSessionAs): Dialog should
4197            be of type wxSAVE and should verify overwriting a file.
4198    
4199            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Use the new
4200            ProjFile.Replace() method instead of the mutator
4201            Projection.SetProjection(). Also requires that we reassign the
4202            client data to the new projection.
4203    
4204            * test/test_proj.py (TestProjection.test): Test GetName() and
4205            GetAllParameters()
4206            (TestProjFile.test): Remove tests for Set*() methods. Add tests
4207            for Replace().
4208    
4209    2003-04-25  Jonathan Coles   <[email protected]>
4210    
4211            * Thuban/Model/save.py (SessionSaver.write_projection): Make sure
4212            to save the name of the projection.
4213    
4214            * test/test_save.py (SaveSessionTest.testLayerProjection): New
4215            test to verify layer projections are saved correctly.
4216    
4217    2003-04-25  Jonathan Coles   <[email protected]>
4218    
4219            * Thuban/Model/proj.py (Projection.SetName): Set the name
4220            to "Unknown" if name is None.
4221            (Projection.SetAllParameters): New. Set the projection's
4222            parameter list to the one supplied.
4223            (Projection.SetProjection): New. Set the projection's
4224            properties to those of the supplied Projection.
4225    
4226            * Thuban/UI/mainwindow.py (MainWindow.MapProjection): Set
4227            the dialog title to include the map's title.
4228            (MainWindow.LayerProjection): Set the dialog title to include
4229            the layer's title.
4230    
4231            * Thuban/UI/projdialog.py (ProjFrame.__ShowError): Consolidate
4232            error dialogs into a single method call.
4233            (ProjFrame.__VerifyButtons): Add more states to check.
4234            (ProjFrame.__GetProjection): Return the current state of an
4235            edited projection or None.
4236            (ProjFrame.__FillAvailList): Remove checks for states that
4237            shouldn't exist.
4238            (ProjFrame._OnNew): Clear all selected items and supply
4239            a projection panel if necessary.
4240    
4241            * test/test_proj.py (TestProjFile.test): Add tests for
4242            ProjFile.SetAllParameters, ProjFile.SetProjection,
4243            ProjFile.SetName.
4244    
4245    2003-04-25  Jonathan Coles   <[email protected]>
4246    
4247            * Thuban/UI/projdialog.py (ProjFrame.__FillAvailList): Now
4248            takes an optional argument to select the current projection.
4249            This does not guarantee that the item is visible due to
4250            limited wxWindows functionality. Fixes RTBug #1821.
4251    
4252    2003-04-25  Jonathan Coles   <[email protected]>
4253    
4254            * Thuban/Model/load.py (SessionLoader.start_projection): Remember
4255            the projection name and use it when constructing the Projection
4256            object.
4257    
4258            * Thuban/Model/proj.py (Projection.__init__): Change the default
4259            value for 'name' to None and then test if name is equal to None
4260            in the body of the constructor. This way the caller doesn't have to
4261            know what the default value should be. Namely, useful in load.py
4262            where we have to pick a default value if the 'name' parameter
4263            doesn't exist in the XML file.
4264    
4265            * test/test_load.py (LoadSessionTest.testLayerProjection): New.
4266            Tests a file where a layer has a projection.
4267    
4268    2003-04-25  Jonathan Coles   <[email protected]>
4269    
4270            * Thuban/Model/layer.py (Layer.TreeInfo): Add an item to the
4271            tree for projection information.
4272    
4273            * Thuban/Model/load.py (XMLReader.GetFilename): Renamed from
4274            XMLReader.GetFileName.
4275            (SessionLoader): Added support for loading projection tags that
4276            appear inside a layer.
4277    
4278            * Thuban/Model/proj.py (ProjFile): Document the class. Move
4279            back to using a list because the order of the projections in
4280            the file is important to maintain. Fixes RTbug #1817.
4281    
4282            * Thuban/Model/resource.py: Rename calls to ProjFile.GetFileName
4283            to ProjFile.GetFilename.
4284    
4285            * Thuban/Model/save.py (SessionSaver.write_layer): Save projection
4286            information.
4287    
4288            * Thuban/UI/projdialog.py (ProjFrame._OnAddToList): Renamed from
4289            ProjFrame._OnSaveAs. Removed old dead code from previous
4290            implementation.
4291            (ProjFrame._OnExport): Add support for exporting more than one
4292            projection to a single file.
4293            (ProjFrame.__FillAvailList): use string formatting (% operator)
4294            to build strings that are (partly) translated. Fixes RTbug #1818.
4295    
4296            * test/test_proj.py (TestProjFile.test): New. Tests the base ProjFile
4297            class.
4298    
4299    2003-04-24  Bernhard Herzog  <[email protected]>
4300    
4301            * po/es.po: Updated Spanish translation by Daniel Calvelo Aros
4302    
4303            * po/fr.po: New. French translation by Daniel Calvelo Aros
4304    
4305            * Thuban/UI/projdialog.py (ProjFrame._OnSaveAs): Don't translate
4306            empty strings.
4307    
4308    2003-04-24  Jonathan Coles   <[email protected]>
4309    
4310            * Thuban/Model/layer.py (Layer.GetProjection): New. Needed to
4311            implement the interface that the ProjFrame dialog expects.
4312    
4313            * Thuban/Model/proj.py (Projection.SetName): New. Allows the
4314            name of the projection to be changed.
4315            (ProjFile): Use a dictionary instead of a list so that removing
4316            projections is easier and we are sure about uniqueness.
4317            (ProjFile.Remove): Remove the given projection object.
4318    
4319            * Thuban/Model/resource.py (GetSystemProjFiles, GetUserProjFiles):
4320            Return a list with only one projection file instead of searching for
4321            any projection file. This simplifies many things if the user can
4322            only have one system file and one user file.
4323    
4324            * Thuban/UI/classgen.py: Change all references to
4325            genCombo to genChoice.
4326    
4327            * Thuban/UI/mainwindow.py: Add a Projection option under the
4328            layer menu.
4329            (MainWindow.LayerProjection): New. Open up a projection window
4330            for a layer.
4331    
4332            * Thuban/UI/projdialog.py: Large changes to how the dialog is
4333            laid out. Use three panels instead of one. One for the list of
4334            projections, one for the edit controls, and one for the buttons.
4335            Fixed resizing problems so that the dialog resizes correctly
4336            when the projection panel changes. Added import/export, save, and
4337            new buttons/functionality.
4338    
4339    2003-04-24  Bernhard Herzog  <[email protected]>
4340    
4341            First step towards table management. Introduce a simple data
4342            abstraction so that we replace the data a layer uses more easily
4343            in the next step.
4344    
4345            * Thuban/Model/data.py: New file with a simple data abstraction
4346            that bundles shapefile and dbffile into one object.
4347    
4348            * Thuban/Model/session.py (Session.OpenShapefile): New method to
4349            open shapefiles and return a shape store object
4350    
4351            * Thuban/Model/layer.py (Layer.__init__): Pass the data as a store
4352            object instead of a shapefile filename. This introduces a new
4353            instance variable store holding the datastore. For intermediate
4354            backwards compatibility keep the old instance variables.
4355            (open_shapefile): Removed. No longer needed with the shape store.
4356            (Layer.SetShapeStore, Layer.ShapeStore): New methods to set and
4357            get the shape store used by a layer.
4358            (Layer.Destroy): No need to explicitly destroy the shapefile or
4359            table anymore.
4360    
4361            * Thuban/UI/mainwindow.py (MainWindow.AddLayer)
4362            (MainWindow.AddLayer): Use the session's OpenShapefile method to
4363            open shapefiles
4364

4366            session's OpenShapefile method to open shapefiles
4367    
4368            * test/test_classification.py
4369            (TestClassification.test_classification): Use the session's
4370            OpenShapefile method to open shapefiles and build the filename in
4371            a more platform independed way
4372    
4373            * test/test_layer.py (TestLayer.setUp, TestLayer.tearDown):
4374            Implement to have a session to use in the tests
4375            (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
4376            (TestLayer.test_point_layer, TestLayer.test_empty_layer): Use the
4377            session's OpenShapefile method to open shapefiles
4378            (TestLayerLegend.setUp): Instantiate a session so that we can use
4379            it to open shapefiles.
4380            (TestLayerLegend.tearDown): Make sure that all references to
4381            layers and session are removed otherwise we may get a resource
4382            leak
4383    
4384            * test/test_map.py (TestMapAddLayer.test_add_layer)
4385            (TestMapWithContents.setUp): Instantiate a session so that we can
4386            use it to open shapefiles.
4387            (TestMapWithContents.tearDown): Make sure that all references to
4388            layers, maps and sessions are removed otherwise we may get a
4389            resource leak
4390            ("__main__"): use support.run_tests() so that more info about
4391            uncollected garbage is printed
4392    
4393            * test/test_save.py (SaveSessionTest.testSingleLayer): Use the
4394            session's OpenShapefile method to open shapefiles
4395            ("__main__"): use support.run_tests() so that more info about
4396            uncollected garbage is printed
4397    
4398            * test/test_selection.py (TestSelection.tearDown): Make sure that
4399            all references to the session and the selection are removed
4400            otherwise we may get a resource leak
4401            (TestSelection.get_layer): Instantiate a session so that we can
4402            use it to open shapefiles.
4403            ("__main__"): use support.run_tests() so that more info about

4407            (TestSessionWithContent.tearDown): Make sure that all references
4408            to the session and layers are removed otherwise we may get a
4409            resource leak
4410            (TestSessionWithContent.setUp): Use the session's OpenShapefile
4411            method to open shapefiles
4412    
4413    2003-04-24  Jonathan Coles   <[email protected]>
4414    
4415            * Thuban/Model/load.py (XMLReader.read): Should have been checking
4416            if the file_or_filename object had the 'read' attribute.
4417    
4418    2003-04-23  Jonathan Coles   <[email protected]>
4419    
4420            * Thuban/Model/resource.py: Fixes RTbug #1813.
4421            (ReadProjFile): Add documentation about which exceptions are raised.
4422            Always pass the exceptions up to the caller.
4423            (GetProjFiles): If the directory can't be read return an empty list.
4424            If any of the proj files can't be read skip that file and go
4425            on to the next one.
4426    
4427            * test/test_proj.py: Added test cases to handle nonexistent files,
4428            unreadable files, and files that don't parse correctly.
4429    
4430    2003-04-23  Jonathan Coles   <[email protected]>
4431    
4432            Projection dialog. Allows the user to select from a list
4433            of projection templates and optionally edit them and save new ones.
4434    
4435            * Thuban/UI/projdialog.py (ProjFrame): New. Main dialog.
4436            (ProjPanel): Base class for projection specific panels.

4438            (UTMPanel): Projection panel for Universal Transverse Mercartor.
4439            (LCCPanel): Projection panel for Lambert Conic Conformal.
4440            (GeoPanel): Projetion panel for Geographic Projection.
4441    
4442    2003-04-23  Jonathan Coles   <[email protected]>
4443    
4444            * Thuban/Model/load.py (XMLReader): Renamed from XMLProcessor to
4445            promote symmetry. There now exists XMLReader and XMLWriter.
4446            (XMLReader.read): New. Call to read the given file descriptor or
4447            filename.
4448            (XMLReader.close): New. Make sure the file is closed.
4449            (XMLReader.GetFileName): New. Return just the file name that is being
4450            read from.
4451            (XMLReader.GetDirectory): New. Return just the directory of the file
4452            that is being read.
4453            (XMLReader.AddDispatchers): New. Take a dictionary which contains
4454            the names of functions to call as the XML tree is parsed.
4455            (XMLReader.startElementNS): Updated to use new dispatcher dictionary.
4456            (XMLReader.endElementNS): Updated to use new dispatcher dictionary.
4457            (SessionLoader): Removed class variables start_dispatcher and
4458            end_dispatcher since this functionality is now part of a class
4459            instance. Fixes RTbug #1808.
4460            (SessionLoader.__init__): Add dispatcher functions.
4461            (load_xmlfile): Code was moved into the XMLReader.read().
4462            (load_session): Use modified SessionLoader.
4463    
4464            * Thuban/Model/map.py (Map.GetProjection): New. Returns the
4465            map's projection.
4466    
4467            * Thuban/Model/proj.py (Projection.GetParameters): Renamed to
4468            GetAllParameters.
4469            (Projection.GetParameter): Returns the value for the given parameter.
4470    
4471            * Thuban/Model/resource.py: Use XMLReader and XMLWriter.

4478            (ProjFileReader): Extend new XMLReader.
4479    
4480            * Thuban/Model/save.py (XMLWriter): Renamed from XMLSaver to
4481            promote symmetry.
4482    
4483            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Use a wxChoice
4484            control instead of a wxComboBox. wxChoice controls do not generate
4485            events as the uses highlights possible choices which fixes problems
4486            with resizing the dialog when the use selects an option.
4487    
4488            * Thuban/UI/classifier.py (Classifier.__init__): Use a wxChoice

4498    
4499            * Thuban/UI/mainwindow.py: Remove some unused imports and global
4500            constants
4501    
4502            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
4503            (IdentifyGridCtrl.selected_shape): Use table, not shapetable.
4504    
4505    2003-04-17  Bernhard Herzog  <[email protected]>
4506    
4507            * Thuban/Model/layer.py: Don't import LAYER_LEGEND_CHANGED.
4508            (Layer): Update doc-string since LAYER_LEGEND_CHANGED is not used
4509            anymore.
4510            (Layer.BoundingBox, Layer.GetFieldType, Layer.NumShapes)
4511            (Layer.ShapeType, Layer.Shape): No need to call
4512            self.open_shapefile since it's always called in __init__
4513    
4514            * Thuban/UI/application.py (ThubanApplication.MainLoop): Removed.
4515            In wxPython 2.4 there's no need to extend MainLoop anymore since
4516            wxPython itself makes sure OnExit is called.
4517    
4518    2003-04-16  Jonathan Coles   <[email protected]>
4519    
4520            Initial putback of projection management code. Includes new
4521            classes to read and write projection files. The current load
4522            and save classes were abstracted a bit so they could be reused.
4523            The Projection class was extended to provide new methods and
4524            have a name.
4525    
4526            * Thuban/Model/load.py (XMLProcessor): New. Contains all the
4527            general XML reading methods that were part of ProcessSession.
4528    
4529            * Thuban/Model/proj.py (Projection.__init__): Accepts an optional
4530            name.
4531            (ProjFile): New. Represents a file that contains projection
4532            information.
4533    
4534            * Thuban/Model/resource.py: New. Contains general utilities
4535            for read and writing projection files.
4536    
4537            * Thuban/Model/save.py (XMLSaver): New. Contains all the
4538            general XML writing methods that were part of SessionSaver.
4539            (SessionSaver): Renamed from Saver.
4540    
4541            * test/test_proj.py: New test cases for the projection
4542            file read and write functions.
4543    
4544    2003-04-16  Jonathan Coles   <[email protected]>
4545    
4546            * Thuban/Model/classification.py: Use repr() around values
4547            in the ClassGroup*.__repr__() methods so it is clearer when
4548            a value is a string and when it is a number.

4555    
4556            Safer implementation of the performance enhancements of the
4557            low-level renderer:
4558            
4559            * extensions/thuban/wxproj.cpp (extract_projection)
4560            (extract_pointer): Rename extract_projection to extract_pointer
4561            and redefine its purpose to return the pointer stored in a CObject
4562            returned by the object's cobject method. Update all callers.
4563            (s_draw_info, free_draw_info, draw_polygon_init): Implement the
4564            handling of these low-level parameters so that each s_draw_info
4565            instance is handled as a CObject at python level that also
4566            contains real references to the actual python objects which
4567            contain the values in the struct. Add free_draw_info as the
4568            destructor.
4569            (draw_polygon_shape): Add the py_draw_info parameter which must a
4570            cobject containing an s_draw_info pointer.
4571

4573            method to instantiat the low-level render parameter
4574            (MapRenderer.draw_shape_layer): Use the new method. Remove some
4575            commented out code.
4576            (MapRenderer.draw_polygon_shape): Make the first parameter not the
4577            layer but the low-level render parameter
4578            (ScreenRenderer.draw_shape_layer): Use the low-level render
4579            parameter.
4580    
4581    2003-04-15  Jonathan Coles   <[email protected]>
4582    
4583            * Thuban/Model/classification.py: Implemented __repr__ for

4585            (ClassGroup.SetLabel): Check that the string is an instance
4586            of StringTypes not StringType. Accounts for Unicode strings.
4587    
4588            * Thuban/Model/color.py: Implemented __repr__ to make
4589            debugging a bit easier.

4592            save the group label.
4593

4599    
4600            * extensions/thuban/wxproj.cpp (draw_polygon_init): New. Used
4601            to improve rendering performance by initializing the variables
4602            that are not change each time draw_polygon_shape() is called.
4603            The values are stored in a global struct draw_info.
4604            (draw_polygon_shape): Removed initialization code that is
4605            now in draw_polygon_init().
4606    
4607            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Make
4608            drawing initialization call to draw_polygon_init()

4663    2003-04-14  Frank Koormann   <[email protected]>
4664    
4665            * Resources/Bitmaps/dock_12.xpm, Resources/Bitmaps/undock_12.xpm:
4666            Updated design to try to make the button functionality more
4667            transparent.

4677    
4678            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Actively
4679            set the current selections in the combo boxes. This is needed
4680            under Windows.
4681    
4682            * Thuban/UI/classifier.py (Classifier.__init__): Add a top
4683            level panel to the dialog so that the background colors are

4695            classifications.
4696

4735    
4736    2003-04-10  Jonathan Coles   <[email protected]>
4737    
4738            * Thuban/Model/classification.py: (ClassGroupRange.__init__):
4739            Should pass group to ClassGroup constructor.
4740    
4741    2003-04-10  Jonathan Coles   <[email protected]>
4742    
4743            * Thuban/Model/classification.py: (ClassGroup): Move all the common
4744            methods of the derived classes ([Set|Get]Properties(), __eq__, __ne__)
4745            here. Implement SetVisible(), IsVisible().
4746            (ClassGroup.__init__): Add group parameter which acts as a copy
4747            constructor.
4748    
4749            * Thuban/UI/classifier.py (ClassTable): Add a new column for the
4750            "Visible" check boxes.

4760            renamed to MainWindow.LayerEditProperties.
4761            (MainWindow.ToggleLegend): Don't include map name in legend title.
4762            (MainWindow.SetMap): Added the map name to the window title.
4763            (MainWindow.LayerFillColor, MainWindow.LayerTransparentFill,
4764            MainWindow.LayerOutlineColor, MainWindow.LayerNoOutline): Removed.
4765            Functionality is found in the layer properties dialog.
4766    
4767            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
4768            draw visible groups.
4769    
4770    2003-04-09  Jonathan Coles   <[email protected]>

4773            addition and selection of new color schemes.
4774            (MonochromaticRamp): New. Generates a ramp between two colors.

4776            (GreenRamp): New. Generates a ramp of all green.
4777            (BlueRamp): New. Generates a ramp of all blue.
4778    
4779    2003-04-09  Jonathan Coles   <[email protected]>
4780    
4781            * Thuban/Model/classification.py (Classification.__deepcopy__):
4782            Need to copy over field and fieldType attributes.
4783    
4784            * Thuban/Model/table.py (Table.field_range): New. Retrive the
4785            maximum and minimum values over the entire table for a given
4786            field.
4787            (Table.GetUniqueValues): New. Retrieve all the unique values
4788            in the table for a given field.
4789    
4790            * Thuban/UI/classgen.py: Renamed GenRangePanel to GenUniformPanel.
4791            (GenUniquePanel): New. Controls to allow the user to select
4792            which unique field values they would like in the classification.
4793            (CustomRampPanel): Code that was in ClassGenDialog that allows
4794            the user to select the properties for a custom ramp.
4795            (ClassGenerator.GenUniformDistribution): Was called GenerateRanges.
4796    
4797            * Thuban/UI/classifier.py: Removed a lot of debugging code.

4799            class generator can set the classification in the grid.
4800            (ClassGroupPropertiesCtrl): New. Encapsulates the drawing and
4801            editing of a group properties class into a wxWindows control.
4802    
4803            * Thuban/UI/dock.py: It was decided that if the user closes
4804            a dockable window the window should simply hide itself. That
4805            way if the user wants to show the dock again it appears in the
4806            same place as it was when it was closed.
4807            (DockableWindow.Destroy): Call renamed method OnDockDestroy().
4808            (DockableWindow._OnButtonClose): Hide the window instead of

4811            destroying it.
4812

4819    
4820            * Thuban/UI/mainwindow.py (main_menu): Move the toggle_legend item
4821            to the map module
4822    
4823    2003-04-07  Bernhard Herzog  <[email protected]>

4831            (MainWindow.ToggleLegend): New method to toggle visibility of the
4832            legend
4833            (MainWindow.ShowLegend): Implement in terms of ToggleLegend and
4834            LegendShown
4835            (MainWindow.LegendShown): New method to return whether the legend
4836            is currently shown.
4837            (_method_command): Add checked parameter so we can define check
4838            menu items
4839            (_has_tree_window_shown, _has_legend_shown): Use the appropriate
4840            mainwindow methods.
4841            (show_session_tree, show_legend commands): Removed.
4842            (toggle_session_tree, toggle_legend commands): New commands to
4843            toggle the visibility of the dialogs
4844    
4845    2003-04-07  Jonathan Coles   <[email protected]>
4846    
4847            * Thuban/UI/classgen.py: Fix Windows problem.
4848    
4849            * Thuban/UI/dock.py: Fix Windows problem.
4850    
4851            * Thuban/UI/mainwindow.py: Use False instead of false.
4852            (MainWindow.ShowLegend): Remove unnecessary switch parameter.
4853    
4854    2003-04-07  Jonathan Coles   <[email protected]>
4855    
4856            Since we now say that the order of the groups in a classification
4857            matters, it makes sense to be able to manipulate that order. Most
4858            of the changes to Thuban/Model/classification.py are to that end.
4859    
4860            * Thuban/Model/classification.py (Classification.AppendGroup,
4861            Classification.InsertGroup, Classification.ReplaceGroup,
4862            Classification.RemoveGroup, Classification.GetGroup): Do as the
4863            names imply.
4864            (Classification.FindGroup): This was called GetGroup, but GetGroup
4865            takes an index, while FindGroup takes a value.
4866            (Classification.__deepcopy__): Copy all the groups, BUT NOT THE LAYER
4867            REFERENCE. Currently there is a cyclic reference between the layer
4868            and its classification. If the classification doesn't need to know
4869            its owning layer we can change this, since it may make sense to be
4870            able to use the same classification with different layers.
4871    
4872            * Thuban/Model/load.py: Use Classification.AppendGroup(), not AddGroup()
4873    
4874            * Thuban/UI/classgen.py: Use Classification.AppendGroup(),
4875            not AddGroup()
4876    
4877            * Thuban/UI/classifier.py: Now that we can depend on the order in
4878            a Classification and have methods to manipulate that order we don't
4879            need to use our own data structures in the grid. We can simply make
4880            the grid/table access the information they need from a copy of
4881            the classification object.
4882            (Classifier._OnCloseBtn): Event handler for when the user clicks
4883            'Close'. This is needed so if the user applies changes and then
4884            continues to change the table the user has the option of discarding
4885            the most recent changes and keeping what they applied.
4886    
4887            * Thuban/UI/mainwindow.py: Put "Show Legend" and "Show Session Tree"
4888            into the same group.
4889    
4890            * extensions/thuban/wxproj.cpp (check_version): If Thuban is compiled
4891            with a really old version of proj, PJ_VERSION won't even be defined.
4892            If it isn't defined then just compile so that the function always
4893            returns Py_False.
4894    
4895            * test/test_classification.py: Fix tests to use the renamed methods.
4896            Still need to write tests for the new methods.
4897    
4898    2003-04-04  Jonathan Coles   <[email protected]>
4899    
4900            * Thuban/UI/classifier.py (Classifier.__SelectField): Move the
4901            call to SetSelection out of the method and before the call
4902            to __SelectField in __init__. This prevents a recursion of events
4903            when _OnFieldSelect is triggered by the user.
4904    
4905    2003-04-04  Jonathan Coles   <[email protected]>
4906    
4907            * Thuban/Model/classification.py: Rename Color.None to
4908            Color.Transparent.
4909            (ClassGroupProperties.SetLineColori, ClassGroupProperties.SetFill):
4910            Don't bother copying the color, since Colors are immutable.
4911    
4912            * Thuban/Model/color.py, Thuban/Model/layer.py, Thuban/Model/load.py,
4913            Thuban/UI/classifier.py, Thuban/UI/mainwindow.py,
4914            Thuban/UI/renderer.py, Thuban/UI/view.py:
4915            Rename Color.None to Color.Transparent.
4916        
4917            * test/test_classification.py, test/test_load.py: Rename Color.None
4918            to Color.Transparent.
4919    
4920    2003-04-04  Jonathan Coles   <[email protected]>

5050    
5051            * Thuban/UI/dock.py: Complete rework on the dock code so that
5052            that it is fairly removed from the rest of the Thuban application.
5053            It is easy to add new docks which the rest of the program having
5054            to be aware of them.
5055    
5056            * Thuban/UI/legend.py: Modifications to support selecting a

5075    
5076    2003-03-26  Jonathan Coles   <[email protected]>
5077    
5078            This putback contains the code for dockable windows. There is
5079            no support in wxWindows as of this date for windows that can
5080            attach themselves to other windows.
5081    
5082            The current model contains a DockableWindow which has a parent
5083            window for when it is detached and a dock window that it puts
5084            its contents in when it is docked. The contents of a DockableWindow
5085            must be a DockPanel. DockPanel itself derives from wxPanel.
5086    
5087            * Thuban/Model/layer.py (Layer.ClassChanged): Send a LAYER_CHANGED
5088            message, not a LAYER_LEGEND_CHANGED message.

5095    
5096            * Thuban/UI/dock.py: New. Classes for the DockPanel and
5097            DockableWindow.
5098    
5099            * Thuban/UI/legend.py: Added some more buttons and made the
5100            LegendPanel a DockPanel.
5101    
5102            * Thuban/UI/mainwindow.py: Added sash windows to the main window
5103            and supporting functions for manipulating the sashes.
5104            (MainWindow.ShowLegend): Create a DockableWindow with the
5105            LegendPanel as the contents.
5106    
5107            * Thuban/UI/messages.py: Added DOCKABLE_* messages
5108    
5109            * Thuban/UI/view.py (MapCanves.SetMap): Listen for LAYER_CHANGED,
5110            not LAYER_LEGEND_CHANGED, messages.
5111    
5112    2003-03-25  Jonathan Coles   <[email protected]>
5113    
5114            * setup.py: Added custom script bdist_rpm_build_script so that
5115            when the rpm is built the path to wx-config is correct.
5116    
5117            * setup.cfg: Added line saying to use the custom build script
5118    
5119    2003-03-20  Jonathan Coles   <[email protected]>
5120    
5121            Initial implementation of the Legend.
5122    
5123            * Thuban/UI/legend.py: New. Creates a window that shows the map's
5124            Legend information and allows the user to add/modify classifications
5125            and how the layers are drawn on the map.
5126    
5127            * setup.py: New command 'build_docs' which currently uses
5128            happydoc to generate html documentation for Thuban.
5129    
5130            * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
5131            Returns a string which is appropriately describes the group.

5137            specific, messages.
5138    
5139            * Thuban/Model/messages.py: New message to indicate that a layer's
5140            data has changed (LAYER_CHANGED). New map messages to indicate
5141            when layers have been added/removed/changed or if the stacking order
5142            of the layers has changed.
5143    
5144            * Thuban/Model/session.py: Rename and use new messages.
5145    
5146            * Thuban/UI/classifier.py: Remember if any changes have actually
5147            been applied so that if the dialog is cancelled without an application
5148            of changes we don't have to set a new classification.
5149            (ClassDataPreviewer): Pulled out the window specific code and put it
5150            ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
5151            symbols on any DC.
5152            
5153            * Thuban/UI/mainwindow.py: New code to open the legend.
5154    
5155            * Thuban/UI/view.py: Use new message names.

5165            the given version against the version of the gtk library
5166            currently being used.
5167    
5168    2003-03-14  Bernhard Herzog  <[email protected]>
5169    
5170            * test/test_command.py: Run the tests when the module is run as a
5171            script
5172    
5173    2003-03-14  Bernhard Herzog  <[email protected]>
5174    
5175            Implement selection of multiple selected shapes in the same layer:
5176    
5177            - Introduce a new class to hold the selection. This basically
5178              replaces the interactor which was nothing more than the
5179              selection anyway. A major difference is of course that the new
5180              selection class supports multiple selected shapes in one layer
5181            
5182            - Move the object that represents the selection from the
5183              application to the canvas. The canvas is a better place than the
5184              application because the selection represents which shapes and
5185              layer of the map displayed by the canvas are selected and
5186              affects how the map is drawn.
5187    
5188            - Make the selection and its messages publicly available through
5189              the mainwindow.
5190    
5191            - The non-modal dialogs do not get a reference to the interactor
5192              anymore as they can simply refer to their parent, the
5193              mainwindow, for the what the interactor had to offer.
5194    
5195            * Thuban/UI/selection.py: New module with a class to represent the
5196            selection.
5197    
5198            * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
5199            these unused messages
5200    
5201            * Thuban/UI/application.py (ThubanApplication.OnInit)
5202            (ThubanApplication.OnExit, ThubanApplication.SetSession): The
5203            interactor is gone now.
5204            (ThubanApplication.CreateMainWindow): There is no interactor
5205            anymore so we pass None as the interactor argument for now for
5206            compatibility.
5207    
5208            * Thuban/UI/view.py (MapCanvas.delegated_messages)
5209            (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
5210            Unsubscribe, delegate messages according to the delegated_messages
5211            class variable.
5212            (MapCanvas.__getattr__, MapCanvas.delegated_methods): Get some
5213            attributes from instance variables as described with the
5214            delegated_methods class variable.
5215            (MapCanvas.__init__): New instance variable selection holding the
5216            current selection
5217            (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
5218            pass them on to the renderer
5219            (MapCanvas.SetMap): Clear the selection when a different map is
5220            selected.
5221            (MapCanvas.shape_selected): Simple force a complete redraw. The
5222            selection class now takes care of only issueing SHAPES_SELECTED
5223            messages when the set of selected shapes actually does change.
5224            (MapCanvas.SelectShapeAt): The selection is now managed in
5225            self.selection
5226    
5227            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
5228            (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
5229            Unsubscribe, delegate messages according to the delegated_messages

5232            attributes from instance variables as described with the
5233            delegated_methods class variable.

5235            parameter is still there for compatibility. The selection messages
5236            now come from the canvas.
5237            (MainWindow.current_layer, MainWindow.has_selected_layer):
5238            Delegate to the the canvas.
5239            (MainWindow.LayerShowTable, MainWindow.Classify)
5240            (MainWindow.identify_view_on_demand): The dialogs don't need the
5241            interactor parameter anymore.

5244            (LayerTableFrame.__init__, LayerTableFrame.OnClose)
5245            (LayerTableFrame.row_selected): The interactor is gone. It's job
5246            from the dialog's point of view is now done by the mainwindow,
5247            i.e. the parent. Subscribe to SHAPES_SELECTED instead
5248            of SELECTED_SHAPE
5249            
5250            * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
5251            is gone. It's job from the dialog's point of view is now done by

5253            
5254            * Thuban/UI/classifier.py (Classifier.__init__): The interactor is
5255            gone. It's job from the dialog's point of view is now done by the
5256            mainwindow, i.e. the parent.
5257    
5258            * Thuban/UI/tree.py (SessionTreeView.__init__): The interactor is
5259            gone. It's job from the dialog's point of view is now done by the
5260            mainwindow, i.e. the parent.
5261            (SessionTreeCtrl.__init__): New parameter mainwindow which is
5262            stored as self.mainwindow. The mainwindow is need so that the tree
5263            can still subscribe to the selection messages.
5264            (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
5265            (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
5266            selection is now accessible through the mainwindow. Subscribe to
5267            SHAPES_SELECTED instead of SELECTED_SHAPE
5268    
5269            * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
5270            SHAPES_SELECTED message now.
5271            (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
5272            so deal with multiple shapes
5273            (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
5274            gone. It's job from the dialog's point of view is now done by the
5275            mainwindow, i.e. the parent.
5276    
5277            * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
5278            parameter is now a list of shape ids.
5279            (RecordTable.SetTable): The second parameter is now a list of
5280            indices.
5281    
5282            * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the
5283            selected_shape parameter and ivar to selected_shapes. It's now a
5284            list of shape ids.
5285            (MapRenderer.draw_label_layer): Deal with multiple selected
5286            shapes. Rearrange the code a bit so that the setup and shape type
5287            distinctions are only executed once.
5288    
5289            * test/test_selection.py: Test cases for the selection class
5290

5294            doesn't cause Thuban to crash.
5295    
5296            * Thuban/Model/layer.py: Handle the cyclic references between
5297            a layer and its classification better, and be sure to disconnect
5298            the classification from the layer when the layer is destroyed
5299            so that we don't maintain a cyclic reference that may not be
5300            garbage collected.
5301    
5302            * Thuban/Model/classification.py: See comment for layer.py.
5303    
5304    2003-03-12  Jan-Oliver Wagner <[email protected]>
5305    
5306            * HOWTO-Release: New. Information on the steps for releasing
5307            a new version of Thuban.
5308    
5309    2003-03-11  Jonathan Coles   <[email protected]>
5310    
5311            * Thuban/UI/classifier.py: Add normal border to SelectPropertiesDialog.
5312            Use True instead of true.
5313            (Classifier): Should have a single panel in which all the controls lie.
5314    
5315            * Thuban/UI/proj4dialog.py: Add normal border.
5316    
5317            * Thuban/UI/tree.py: Fixed problem with bad item images under Windows.
5318    
5319            * Thuban/UI/mainwindow.py: Use True instead of true.
5320    
5321            * setup.py: Update some definitions to use wxWindows2.4 files
5322    
5323            * Data/iceland_sample_class.thuban: Fixed file so that the
5324            field_type information is present.
5325    
5326    2003-03-10  Jonathan Coles   <[email protected]>
5327    
5328            * Thuban/UI/classifier.py (Classifier.__init__): Make the
5329            field type label grow so that when the text changes the
5330            size is updated correctly. This may be a wxWindows bug.
5331    
5332    2003-03-10  Jonathan Coles   <[email protected]>
5333    
5334            * Thuban/UI/application.py: Changed SESSION_CHANGED to
5335            SESSION_REPLACED.
5336    
5337            * Thuban/UI/classifier.py: Wrap text with _().
5338            (ClassGrid.CreateTable): Set dimensions and size hints here,
5339            instead of in Reset, so we only set the size once.
5340    
5341            * Thuban/UI/dialogs.py: Don't need Shutdown(); just use Close()!
5342    
5343            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
5344            Call Close() instead of Shutdown().
5345    
5346            * Thuban/UI/messages.py: Changed SESSION_CHANGED to SESSION_REPLACED.
5347    
5348            * Thuban/UI/tree.py: Changed SESSION_CHANGED to SESSION_REPLACED.
5349            Go back to using OnClose() instead of Shutdown().
5350    
5351    2003-03-10  Jonathan Coles   <[email protected]>
5352    
5353            * Thuban/UI/classifier.py (Classifier): SelectField() needed
5354            to know the old field index as well as the new one.
5355    
5356    2003-03-10  Jonathan Coles   <[email protected]>
5357    
5358            * Thuban/UI/classifier.py (Classifier): Use __SelectField()
5359            to correctly set the table information and call this from
5360            __init__ and from _OnFieldSelect so that all the information
5361            is up to date when the dialog opens and when a field is changed.
5362    
5363    2003-03-10  Jonathan Coles   <[email protected]>
5364    
5365            * Thuban/Model/classification.py (Classification): Don't use
5366            layer's message function directly, use the ClassChanged() method
5367            when then classification changes. SetField/SetFieldType/SetLayer
5368            must keep the information about field name and field type in
5369            sync when an owning layer is set or removed.
5370    
5371            * Thuban/Model/layer.py: Added ClassChanged() so that the
5372            classification can tell the layer when its data has changed.
5373            (Layer.SetClassification): Accepts None as an arguement to
5374            remove the current classification and correctly handles
5375            adding a new classification.
5376    
5377            * Thuban/Model/load.py: Comment out print statement
5378    
5379            * test/test_classification.py, test/test_save.py: New and
5380            improved tests.
5381    
5382    2003-03-07  Jonathan Coles   <[email protected]>
5383    
5384            * Thuban/Model/classification.py: Implemented __copy__ and
5385            __deepcopy__ for ClassGroup* and ClassGroupProperites so
5386            they can easily be copied by the classifier dialog.
5387            (ClassGroupProperites.__init__): The default line color should
5388            have been Color.Black.
5389    
5390            * Thuban/UI/classifier.py: Setting and Getting table values now
5391            uses a consistent set of functions.
5392            (Classifier): Now non-modal. Has field type label which changes
5393            as the field changes. Keep track of buttons in a list so that
5394            we can enable/disable the buttons when the None field is selected.
5395            (SelectPropertiesDialog): Add buttons to make the colors transparent.
5396    
5397            * Thuban/UI/dialogs.py (NonModalDialog.Shutdown): New method which
5398            does what OnClose did, but can be called by the application to
5399            close a window. Needed when a session changes, and we have to
5400            close the classifier windows.
5401    
5402            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
5403            Shuts down open dialogs. Used when a new session is created
5404            or a session is opened.
5405            (MainWindow.SaveSession): Should only call application.SaveSession()
5406            if we don't call SaveSessionAs first.
5407            (MainWindow.Classify): Allow different classifier dialogs for
5408            different layers.
5409    
5410            * Thuban/UI/tree.py (SessionTreeView): Remove OnClose and let
5411            the parent class handle it. Add Shutdown() to unsubscibe from
5412            event notification and call the parent Shutdown(). This was
5413            necessary so the application can close the tree window.
5414    
5415    2003-03-06  Jonathan Coles   <[email protected]>
5416    
5417            * Thuban/Model/classification.py: Minor documentation changes,
5418            Addition of __eq__ and __ne__ methods.
5419            (Classification.SetLayer): prevent recursion between this method
5420            and Layer.SetClassification().
5421    
5422            * Thuban/Model/color.py: Addition of __eq__ and __ne__ methods.
5423    
5424            * Thuban/Model/layer.py (SetClassification): prevent recursion
5425            between this method and Classification.SetLayer().
5426    
5427            * test/test_classification.py, test/test_load.py,
5428            test/test_session.py: Fixed and added tests for the classification
5429            classes.
5430    
5431    2003-03-06  Bernhard Herzog  <[email protected]>
5432    
5433            * Thuban/UI/classifier.py (ClassGrid.__init__)
5434            (ClassGrid.CreateTable): Move the SetSelectionMode call to
5435            CreateTable because otherwise it triggers an assertion in
5436            wxPython/wxGTK 2.4.
5437    
5438    2003-03-05  Jonathan Coles   <[email protected]>
5439    
5440            * Thuban/common.py: Move FIELDTYPE constants back to table.py.
5441    
5442            * Thuban/Model/load.py: import FIELDTYPE constants from table.
5443    
5444            * Thuban/UI/classifier.py: import FIELDTYPE constants from table.
5445    
5446            * Thuban/Model/table.py: Put FIELDTYPE constants back.
5447    
5448    2003-03-05  Jonathan Coles   <[email protected]>
5449    
5450            * Thuban/UI/classifier.py: Added class documentation.
5451            Fixed RTbug #1713, #1714. Added Move[Up|Down] buttons.
5452            Store just the groups in the table and generate the other
5453            column information when it is requested. Add "None" field
5454            to pull-down to select no classification.
5455    
5456            * Thuban/common.py: Moved FIELDTYPE constants from table.py
5457            (Str2Num): Only catch ValueError exceptions.
5458    
5459            * Thuban/Model/classification.py: Class documentation. Renaming
5460            of methods with Stroke to Line. Groups are stored in a single
5461            list with the default as the first element. Groups are searched
5462            in the order they appear in the list.
5463    
5464            * Thuban/Model/color.py: Documentation.
5465    
5466            * Thuban/Model/layer.py (Layer): Add GetFieldType to retreive
5467            the kind of data represented by a field.
5468    
5469            * Thuban/Model/load.py (ProcessSession): Use proper string
5470            conversion function; fixes RTbug #1713.
5471    
5472            * Thuban/Model/save.py (Saver): Store field type information.
5473    
5474            * Thuban/Model/table.py: Put FIELDTYPE constants in common.py.

5476            by specifying the field name, not the number.
5477    
5478            * Thuban/UI/mainwindow.py: Function name changes.
5479    
5480            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
5481            get the layer classification once. Don't try to classify
5482            values when the field is None: just use the default properties.
5483    
5484            * Thuban/UI/view.py: Function name changes.
5485    
5486            * Doc/thuban.dtd: Add field_type attribute to a classification.
5487    
5488    2003-03-04  Bernhard Herzog  <[email protected]>
5489    
5490            * Doc/thuban.dtd: Use correct syntax for optional attributes. Make
5491            the fill and stroke layer attributes optional with suitable
5492            default values. Add the stroke_width layer attribute. Use correct
5493            syntax for empty elements. Make the attribute list for labels
5494            refer to the label element.
5495    
5496    2003-03-04  Bernhard Herzog  <[email protected]>
5497    
5498            * setup.py (thuban_build_py.build): Add a comment about distutils in
5499            Python 2.3 containing some of the functionality we implement in
5500            setup.py ourselves.
5501    
5502            * Thuban/UI/classifier.py (ClassGrid.__init__): Set the table
5503            before the selection mode. Doing it the other way round triggers
5504            an assertion in wxWindows.
5505    
5506            * Thuban/Model/save.py (escape): Fix typo in doc-string
5507    
5508            * Thuban/Model/classification.py: Remove unnecessary wxPython
5509            import

5514            Parameter 'value' should default to None.
5515    
5516            * Thuban/UI/mainwindow.py: Use Layer.GetClassification() since
5517            the class attribute __classification is now private.
5518    
5519            * Thuban/UI/classifier.py (ClassGrid): Moved OnCellDClick() from
5520            Classifier to ClassGrid. Added support for removing selected rows,
5521            which including code for keeping track of when cells are selected,
5522            and deselected.
5523            (ClassTable): Support for added/removing rows. Fixed a problem
5524            with __ParseInput whereby it would not allow strings (only numbers)
5525            to be entered.
5526            (Classifier): Added button and supporting code for removing
5527            selected rows.
5528    
5529    2003-02-27  Jonathan Coles   <[email protected]>
5530    
5531            * Thuban/common.py: Moved color conversion functions into
5532            Thuban/UI/common.py.
5533            (Str2Num): Now converts the float (not the string) to a long/int
5534            so that an exception isn't thrown.
5535    
5536            * Thuban/UI/common.py: Common functions used in several UI modules
5537    
5538            * Thuban/Model/classification.py: Changed the class hierarchy
5539            so that a Classification consists of Groups which return
5540            Properties when a value matches a Group.
5541    
5542            * Thuban/Model/layer.py: Fixed name resolution problem.
5543    
5544            * Thuban/Model/load.py: Use new Classification and Group functions.
5545    
5546            * Thuban/Model/save.py (Saver.write_attribs): Fixes a test case
5547            failure.
5548            (Saver.write_classification): Use new Classification and Group
5549            functions.
5550    
5551            * Thuban/UI/classifier.py: Changes to use new Classification and Group
5552            functions. Fix to create a tuple with a single value instead of
5553            simply returning the value.
5554    
5555            * Thuban/UI/renderer.py: Use new Classification and Group functions.
5556            Use common.py functions.

5558            * Thuban/UI/tree.py: Use common.py functions.
5559            
5560            * test/test_classification.py: Use new Classification and Group
5561            classes.

5580    
5581            * Thuban/UI/mainwindow.py (MainWindow.OpenSession,
5582            MainWindow.SaveSessionAs): Text string changes so the dialogs
5583            have more meaningful titles.
5584    
5585            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Change
5586            Classification method name from GetProperties to GetClassData.
5587    
5588            * Thuban/UI/view.py (MapCanvas.find_shape_at): Use method calls
5589            instead of accessing now non-existent class variables.
5590

5592    
5593            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Remove
5594            unneeded Shape() call. Rendering is substantially faster without
5595            it and it avoids some problems with broken shape files.
5596    
5597    2003-02-20  Frank Koormann   <[email protected]>
5598    
5599            Force minimal size of identify and label dialogs. The autosizing
5600            looked too ugly.
5601    
5602            * Thuban/UI/controls.py (RecordListCtrl): Set minimal width for columns.
5603            * Thuban/UI/labeldialog.py (LabelDialog.dialog_layout):

5624    
5625            * Thuban/Model/color.py: Added Color.None to represent something
5626            with no color. Color.Black represents the color black.
5627            (NoColor): Helper class derived from Color to represent something
5628            with no color.
5629    
5630            * Thuban/Model/layer.py (Layer): Removed references to fill, stroke,
5631            stroke_width attributes. Made the 'classification' attribute private.
5632            New methods for setting/getting the classification.
5633    
5634            * Thuban/Model/load.py (ProcessSession): Use new methods on Layer
5635            to get the classifcation and use the new ClassData* classes to
5636            hold the classification data. Use Str2Num to convert numbers
5637            properly.
5638    
5639            * Thuban/Model/save.py (Saver): Use new Color and Classification
5640            methods

5651            (ClassPreviewer): Took the Draw method from ClassRenderer and
5652            made most of it into this new class. Intend to use this class in
5653            the SelectPropertiesDialog for previewing changes.
5654    
5655            * Thuban/UI/renderer.py: Use new Color and Classification methods.
5656

5678            (ThubanApplication.OnInit): Call the
5679            new splash_screen method to determine whether the application
5680            should display a splash screen. If it displays a splash screen do
5681            not immediately show the main window.
5682    
5683    2003-02-11  Jonathan Coles  <[email protected]>
5684    
5685            * Thuban/Model/classification.py: Added import line to fix
5686            feature conflicts between running on python2.2 and python2.1.
5687    
5688            * Thuban/UI/classifier.py (ClassTable): Didn't need to hang
5689            onto the clinfo parameter, so removed the deepcopy().
5690    
5691    2003-02-10  Jonathan Coles  <[email protected]>
5692    
5693            * Thuban/Model/save.py (Saver.open_element, Saver.close_element):
5694            Added element_open variable to track opening and closing of tags
5695            so that tags that don't span more than one line are closed with
5696            /> instead of </tag_name>. Use the GetDefault*() methods of
5697            the Classification class.
5698    
5699            * Thuban/Model/classification.py (Classificaton): Added set and
5700            get methods for the default data. The class also takes a layer
5701            reference so that modification messages can be sent. Fixed the
5702            methods to use the new ClassData class.
5703            (ClassData): New class to encapsulate the classification data
5704    
5705            * Thuban/Model/layer.py (Layer): Remove the
5706            Set[Fill|Stroke|StrokeWidth]() methods. Code should call the
5707            SetDefault*() methods on the layer's classification object.
5708            (Layer.__init__): Use the new SetDefault*() methods in the
5709            Classification class.

5718            * Thuban/UI/mainwindow.py (MainWindow): Use the SetDefault*()
5719            methods of the Classification class.
5720    
5721            * Thuban/UI/renderer.py (MapRenderer): Use the Get*() methods
5722            of the ClassData class.
5723    
5724            * test/test_classification.py, test/test_layer.py,
5725            test/test_map.py, test/test_session.py: Fix the tests to work
5726            with the above code changes.

5731            to return the NullData reference
5732    
5733            * Thuban/Model/layer.py (Layer.SetFill, Layer.SetStroke,
5734            Layer.SetStrokeWidth): Modified these functions to change the
5735            null data in the classification rather than keep these values
5736            directly in the Layer class. Menu options to change these values
5737            work again.
5738    
5739    2003-01-28  Jonathan Coles  <[email protected]>
5740    
5741            * Thuban/UI/classifier.py (Classifier): Resolved merging conflicts.
5742            Fixed crashing problem on some systems. Dialog box shows
5743            classification data.
5744    
5745            * Thuban/UI/tree.py (SessionTreeCtrl.add_items): Handle drawing
5746            Colors in the tree view.
5747    
5748            * Thuban/Model/layer.py (Layer.TreeInfo): Added a call to build
5749            the tree info for classifications. Commented out unnecessary lines.
5750    
5751            * Thuban/Model/classification.py (Classification.TreeInfo): New
5752            function to add information about the classification into the
5753            tree view.
5754    
5755    2003-01-27  Jan-Oliver Wagner <[email protected]>
5756

5824    
5825    2002-11-06  Frank Koormann  <[email protected]>
5826    
5827            * Thuban/UI/mainwindow.py: Altered the order of tools in the
5828            toolbar: First now are all navigation tools (Zoom In/Out, Pan,
5829            Full Extent).
5830    
5831    2002-10-23  Bernhard Herzog  <[email protected]>

5850            message if the assertion fails and don't return the return value
5851            of self.assert_. In assertFloatSeqEqual the return meant that not
5852            all items of the sequence were compared.
5853    
5854    2002-09-20  Bernhard Herzog  <[email protected]>
5855

5862            differences in the way %g is handled.
5863    
5864            * test/test_layer.py (TestLayer.test_empty_layer): Create an empty
5865            DBFfile too because Thuban layers can't yet cope missing DBF
5866            files.
5867    
5868    2002-09-20  Bernhard Herzog  <[email protected]>
5869

5909    
5910            * Thuban/UI/mainwindow.py (MainWindow.view_position_changed)
5911            (MainWindow.set_position_text): Put the code that puts the text
5912            with the mouse position into the status bar into the new method
5913            set_position_text so that it can overwritten in derived classes.
5914    
5915    2002-09-12  Bernhard Herzog  <[email protected]>
5916    
5917            * Thuban/UI/mainwindow.py (MainWindow.RunMessageBox): Center the
5918            message box on the main window.
5919    
5920    2002-09-11  Bernhard Herzog  <[email protected]>
5921    
5922            * Thuban/UI/mainwindow.py: Underline the 'x' in "Exit" instead of
5923            the 'E' because it's less likely to interfere with other menu
5924            entries.
5925            (MainWindow.build_menu): remove an incorrect comment.
5926    
5927    2002-09-10  Bernhard Herzog  <[email protected]>

5943            * Resources/Bitmaps/fullextent.xpm: Updated Icon (removed "potatoe")
5944    
5945    2002-09-02  Bernhard Herzog  <[email protected]>
5946    
5947            * Thuban/UI/view.py: Get rid of the idle redraw. This is done by
5948            wxWindows already and our implementation doesn't work correctly
5949            with wxGTK 2.3:
5950            (MapCanvas.__init__): Remove the instance variable
5951            (MapCanvas.OnPaint): Always call do_redraw when there's a map to
5952            be drawin
5953            (MapCanvas.OnIdle): Removed.
5954    
5955            * Thuban/UI/view.py (MapCanvas.unprojected_rect_around_point): Add
5956            a parameter to determine the size of the rectangle.
5957            (MapCanvas.find_shape_at): Create the box around the point on a
5958            layer by layer basis and make the size depend on the shape type.
5959            This solves a problem with the selection of point shapes at the
5960            border of the layer's bounding box
5961    
5962    2002-08-30  Bernhard Herzog  <[email protected]>
5963    
5964            * Thuban/UI/mainwindow.py (MainWindow.CanRemoveLayer): New method
5965            for the sensitivity  of remove layer.

5977    
5978            * test/: new subdirectory with a bunch of unit tests.
5979

5981            test/test_menu.py, test/test_load.py: Initial set of tests and
5982            brief instructions on how to run them
5983    
5984    2002-08-29  Bernhard Herzog  <[email protected]>
5985    
5986            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Handle
5987            arcs with multiple parts.
5988    
5989            * Thuban/UI/view.py (ZoomInTool.MouseUp, ZoomOutTool.MouseUp):
5990            Handle degenrate rectangles.
5991    
5992            * Thuban/Model/table.py: Make writing records work correctly:

5994            writing
5995            (Table.write_record): Open the DBF file for writing when necessary
5996    
5997    2002-08-27  Bernhard Herzog  <[email protected]>
5998    
5999            * Thuban/Model/table.py (Table.write_record, Table.__init__): Open
6000            dbf files only for reading by default. Use a new writable dbf
6001            object for writing.
6002    
6003    2002-08-26  Bernhard Herzog  <[email protected]>
6004    
6005            * Thuban/UI/mainwindow.py: Refactor the context creation:
6006            (MainWindow.Context): New method to return a context
6007            (MainWindow.invoke_command, MainWindow.update_command_ui): Use the
6008            new method
6009    
6010            * Thuban/UI/tableview.py (TableGrid, LayerTableGrid): Split the
6011            layer table specific code from TableGrid into LayerTableGrid
6012            (TableFrame, LayerTableFrame): Split the layer table specific code
6013            from TableFrame into LayerTableFrame
6014            (LayerTableGrid.select_shape): Remove a debug print
6015    
6016            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Use the
6017            LayerTableFrame
6018    
6019    2002-08-23  Bernhard Herzog  <[email protected]>
6020    
6021            * Thuban/Model/layer.py (Layer.__init__): Make sure we have an
6022            absolute filename.
6023    
6024    2002-08-22  Bernhard Herzog  <[email protected]>
6025    
6026            * Thuban/Model/table.py (Table.write_record): New method to write
6027            records.
6028            (Table.__init__): Open the DBF file for writing too.
6029    
6030            * Thuban/UI/controls.py (RecordTable.SetValue): Write the value
6031            into the underlying table.
6032    
6033            * extensions/shapelib/shapefil.h (DBFCommit),
6034            extensions/shapelib/dbfopen.c (DBFCommit): New API function to
6035            commit any changes made to the DBF file.
6036    
6037            * Thuban/UI/mainwindow.py (make_check_current_tool)
6038            (_tool_command): Put the code that generates the "checked"
6039            callback into a separate function so that we can reuse it
6040            elsewhere
6041    
6042            * Thuban/Model/save.py (Saver): New class to handle serializing a
6043            session into an XML file. The main reason to introduce a class is
6044            that applications built on Thuban can derive from it so that they
6045            can save additional information in a session file.
6046            (save_session): Delegate almost all the work to the Saver class.
6047            Rename the filename argument to file because it may be a file like
6048            object now.
6049    
6050            * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
6051            code. Remove the little test code which would be executed when the
6052            module is run as a script which didn't work anymore since it can't
6053            import the other Thuban modules.
6054            (ProcessSession, load_session): Refactor the ProcessSession to
6055            have one method for each element start and end tag so that derived
6056            classes can easily override the processing of individual tags.
6057            Also, always parse with namespaces enabled because applications
6058            built on top of Thuban will likely use namespaces if they extend
6059            the session file format.
6060    
6061  2002-08-21  Bernhard Herzog  <[email protected]>  2002-08-21  Bernhard Herzog  <[email protected]>
6062    
6063          * setup.py (ThubanInstall.run): Don't repr install_lib_orig          * setup.py (ThubanInstall.run): Don't repr install_lib_orig
