1    2003-06-13  Bernhard Herzog  <[email protected]>
2    
3            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
4            self.selected_shape with the current selection to make sure the
5            contents of the dialog are up to date when it's shown for the
6            first time.
7            The dialog used to work without this by luck. The recent fix to
8            the connector module 'broke' a 'feature' the identify view was
9            relying on, i.e that subscribing to a message in response to
10            receiving a message of that type would mean that the new
11            subscriber would also be called for the same message.
12    
13    2003-06-12  Jonathan Coles   <[email protected]>
14    
15            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
16            the scalebar if the current map has no projection set.
17    
18            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
19            projfilepath label to just the basename of the projection file
20            rather than include the entire path.
21

27    2003-06-11  Frank Koormann  <[email protected]>
28    
29            * Thuban/Lib/fileutil.py (get_application_dir): New function to

41            the messages MAP_LAYERS_REMOVED messages
42            (LayerTableFrame.OnClose): Unsubscribe from it.
43            (LayerTableFrame.map_layers_removed): New. Receiver for
44            MAP_LAYERS_REMOVED. Close the dialog when the layer whose the
45            dialog is showing is removed.
46    
47    2003-06-10  Bernhard Herzog  <[email protected]>
48    
49            * Thuban/Lib/connector.py (Connector.Issue): Iterate over a copy
50            of the receivers list so that unsubscribing in a receiver doesn't
51            modify it while iterating over it.
52    
53            * test/test_connector.py
54            (ConnectorTest.test_disconnect_in_receiver): New. Test whether
55            unsubscribing in a receiver works correctly. See docstring for
56            details
57    
58    2003-06-10  Bernhard Herzog  <[email protected]>
59    
60            * Thuban/Model/messages.py (LAYER_SHAPESTORE_REPLACED): New

62    
63            * Thuban/Model/layer.py (Layer.SetShapeStore): Send
64            LAYER_SHAPESTORE_REPLACED when the shapestore changes. A
65            LAYER_CHANGED will still be sent if the classification changes.
66    
67            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
68            parameter so we can subscribe to some of its messages

76    
77            * Thuban/UI/mainwindow.py (MainWindow.OpenLayerProperties): Pass
78            the map to the Classifier dialog
79    
80            * test/test_layer.py (SetShapeStoreTests): Derive from
81            SubscriberMixin as well so we can test messages
82            (SetShapeStoreTests.setUp): Subscribe to some of the layer's
83            messages
84            (SetShapeStoreTests.tearDown): Clear the messages again
85            (SetShapeStoreTests.test_sanity): Expand the doc-string and check

89            (SetShapeStoreTests.test_set_shape_store_different_field_name)
90            (SetShapeStoreTests.test_set_shape_store_same_field)
91            (SetShapeStoreTests.test_set_shape_store_same_field_different_type):
92            Add tests for the messages. This checks both the new

99    
100    2003-06-05  Frank Koormann  <[email protected]>
101    
102            * Thuban/UI/identifyview.py (IdentifyView.__init__):
103            Layout reimplemented without panel. Make life easier to fit the list
104            in the dialog.
105    
106    2003-06-05  Frank Koormann  <[email protected]>
107    
108            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
109            once on initialisation (Former implementation resulted in multiple
110            entries for each projection).
111            (ProjFrame.__FillAvailList): selectProj as second optional parameter,
112            if set, select the projection found under the specified name. This
113            overwrites any other selection estimate.
114            Removed projchoice filling from this method.
115            (ProjFrame._OnSave, ProjFrame._OnAddToList):
116            Updated call of ProjFrame.__FillAvailList
117            (LCCPanel._DoLayout): Moved parameter controls in more common order.
118    
119            * Resources/Projections/defaults.proj: Extended defaults representing
120            various common European projections.
121    
122    2003-06-05  Frank Koormann  <[email protected]>
123    
124            * Thuban/UI/identifyview.py (IdentifyView.__init__):
125            Use ListCtrl instead of GridCtrl
126    
127            * Thuban/Model/resource.py:
128            Guess location of .thuban directory from tempdir parent directory.
129    
130            * Thuban/UI/application.py (ThubanApplication.read_startup_files):
131            Guess location of .thuban directory from tempdir parent directory.
132    
133    2003-06-04  Bernhard Herzog  <[email protected]>
134    
135            Do not cache the values returned by the tree widget's
136            GetFirstChild and GetNextChild methods because it led to lots of
137            segfaults. The new way requires more brute force but is more
138            reliable.
139    
140            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
141            variable layer2id
142            (LegendTree.find_layer): New method to do with brute force what
143            layer2id tried to accomplish
144            (LegendTree._OnMsgLayerChanged)
145            (LegendTree._OnMsgLayerTitleChanged, LegendTree.__ShowHideLayer):
146            Use find_layer instead of layer2id
147            (LegendTree.__RemoveLayer, LegendTree.__AddLayer): No need to
148            update layer2id anymore
149            (LegendTree._OnMsgMapLayersRemoved)
150            (LegendTree._OnMsgMapLayersAdded): Get by without layer2id.
151    
152    2003-06-03  Thomas Koester  <[email protected]>
153    
154            * Thuban/Model/classgen.py (GenQuantiles0): New function.
155    
156    2003-06-02  Bernhard Herzog  <[email protected]>
157    
158            * Thuban/UI/mainwindow.py (layer_rename command, table_rename command):
159            New commands.
160            (main_menu): Add the new commands.
161            (MainWindow.TableRename): New. Implementation of the table_rename
162            command.
163            (MainWindow.RenameLayer): New. Implementation of the layer_rename
164            command.

170            whether the modified flag is set properly
171    
172            * Thuban/Model/base.py (TitledObject.SetTitle): Call changed
173            instead of issue so that the modified flags get updated.
174    
175            * test/test_base.py (SomeTitledObject): Derive from Modifiable
176            instead of Publisher to reflect reality better and to accomodate
177            the fact that SetTitle now calls changed instead of issue
178    
179    2003-06-02  Bernhard Herzog  <[email protected]>
180    
181            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource
182            acquisition has to happen before the try in a try-finally.
183    
184    2003-06-02  Bernhard Herzog  <[email protected]>
185    
186            * Thuban/UI/legend.py (LegendTree._OnMsgMapLayersRemoved): It's
187            possible that a layer is removed that is not currently selected in
188            the legend so don't check for this.
189    
190    2003-05-30  Bernhard Herzog  <[email protected]>
191    
192            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
193            variables to None that have direct or indirect references to
194            shapefiles or dbf files to make sure that they do go away and the
195            files are closed.

198    
199            * Thuban/UI/legend.py (LegendTree.GetRootItem): Reset
200            availImgListIndices when a new image list is created
201            
202    2003-05-30  Bernhard Herzog  <[email protected]>
203    
204            * Thuban/UI/legend.py (LegendTree.__init__): New instance variable
205            changing_selection to indicate whether the LegendTree code itself
206            is currently changing the selection
207            (LegendTree.normalize_selection): New method to normalize the
208            selection by selecting the layer item even if the user clicked on
209            the classification.
210            (LegendTree._OnSelChanged): normalize the selection. This works
211            around a bug in wx which doesn't keep track of the selection
212            properly when subtrees are deleted.
213    
214    2003-05-30  Bernhard Herzog  <[email protected]>

229            RTBug #1907.
230    
231            * Thuban/UI/classgen.py: Use classgen functions that were part
232            of the ClassGenerator class. Put try/finally blocks around
233            code that uses wxBeginBusyCursor()/wxEndBusyCursor(). Fixes
234            RTBug #1904.
235    
236            * Thuban/UI/classifier.py: Remove unused import of ClassGenerator.
237    
238            * Thuban/UI/legend.py: The legend was cleared and repopulated any
239            time something changed which caused some state to be lost such
240            as which children were expanded or collapsed. Fixes RTBug #1901.
241            (LegendTree._OnMsgMapLayersAdded): Add only new layers.
242            (LegendTree.__OnMsgMapLayersRemoved): Remove layers that exist in

246            (LegendTree.__FillTreeLayer): Reuse old slots in the image list
247            if they are available.
248            (LegendTree.DeleteAllItems): Renamed from __DeleteAllItems so
249            that we override the wxTreeCtrl method. Iterate over children
250            and call __RemoveLayer.
251            (LegendTree.__AddLayer): New. Add a new layer to the legend.
252            (LegendTree.__RemoveLayer): Remove a layer from the legend.
253            (LegendTree.DeleteChildren): New, overrides wxTreeCtrl method.
254            Should only be called with the id of a layer branch.
255            (LegendTree.GetRootItem): New, overrides wxTreeCtrl method.
256            Returns the root item or creates one if necessary.
257    
258            * Thuban/UI/renderer.py (MapRenderer.draw_raster_layer): Call
259            ProjectRasterFile with tuple arguments instead of strings.
260    
261            * Thuban/UI/tableview.py (QueryTableFrame.OnQuery): Wrap code
262            with try/finally. Fixes RTBug #1904.
263    
264            * Thuban/UI/view.py (MapCanvas.OnPaint): Wrap code
265            with try/finally. Fixes RTBug #1904.
266            (MapCanvas.FitSelectedToWindow): If a single point is selected
267            simply center it on the display. Fixes RTBug #1849.
268    
269            * extensions/thuban/gdalwarp.cpp: Removed code that allowed gdalwarp
270            to be compiled as a standalone app. Now the code can only be
271            called from Python which simplifies the parameter passing.
272            (ProjectRasterFile): Handle Python arguments. Remove code that
273            checks for a destination dataset. Add more clean up code.
274    
275            * test/test_map.py (TestMapWithContents.test_raise_layer_top,
276            TestMapWithContents.test_lower_layer_bottom):
277            Test Map.MoveLayerToTop() and Map.MoveLayerToBottom() respectively.

296    2003-05-28  Bernhard Herzog  <[email protected]>
297    
298            * Thuban/UI/tableview.py (NullRenderer.Draw): New. Our own
299            renderer so that NULL/None values get displayed differently (by a
300            gray rectangle).

312    
313            * Thuban/Model/layer.py (Layer.TreeInfo): Fixed a bug (a layer
314            does not necessarily have a filename).
315    
316    2003-05-28  Jan-Oliver Wagner <[email protected]>
317

604            to a layer.
605    
606            * Thuban/UI/mainwindow.py (MainWindow.TableShow): A very coarse
607            implementation that still needs work.

794    2003-05-22  Frank Koormann  <[email protected]>
795    
796            UI polishing updates: Place main buttons (OK, Cancel, etc) in the
797            lower right corner, center labels for selections, initialize controls
798            in reasonable order for keyboard navigation.
799    
800            * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
801            (ProjFrame.__DoOnProjAvail): Determine position of current projection
802            using the wxListBox.FindString() method. Still a problem (#1886)
803    
804            * Thuban/UI/classifier.py
805            (Classifier.__init__, SelectPropertiesDialog.__init__)
806    
807            * Thuban/UI/classgen.py (ClassGenDialog.__init__,
808            (ClassGenDialog.__DoOnGenTypeSelect): Moved initialization of the
809            different classification types from here to __init__.
810            (GenUniquePanel.__init__): Set the column width of the first field
811            in the Field ListCtrl to the full width.
812    
813            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Rename 'Save As'
814            Button to 'Export'. Center Buttons in Selection Box, set Focus to
815            Grid.
816            (LayerTableFrame.OnKeyDown()): New, bound to the grid with EVT_KEY_DOWN,
817            changes focus to the Selection when pressing "Alt-S".
818    
819            * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
820            the text if not visible. The italic font sometimes exceeds the
821            rendering area.
822    
823    2003-05-21  Jonathan Coles   <[email protected]>
824    
825            * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
826            to OnClose so that Thuban closes correctly.
827    
828            * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
829            DockFrame.OnClose, not DockFrame._OnClose.
830    
831    2003-05-21  Jonathan Coles   <[email protected]>
832    
833            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
834            references to 'inf' and use new Range __init__ to pass floats
835            directly rather than converting them to strings first.
836            Fixes RTBug #1876.
837    
838            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
839            Use new Range ___init__ to pass floats.
840    
841            * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
842            filename is a valid image file. Throw IOError otherwise.
843    
844            * Thuban/Model/range.py: Brought over new Range from SciParam that
845            is immutable and has an __init__ which can accept floats.
846    
847            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
848            into try block. AddLayer doesn't throw any exceptions anymore.
849            (MainWindow.AddRasterLayer): Move constructor of RasterLayer into
850            try block.
851    
852            * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as
853            the first item in choices. Fixes RTBug #1882.
854    
855            * Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale
856            has gone to 0 which is a serious problem. abort.
857            (MapRenderer.draw_raster_layer): Catch IOError seperately and
858            print the error from GDAL.
859    
860            * Thuban/UI/tableview.py (TableGrid.__init__): Call
861            ToggleEventListeners to turn on listening.
862            (TableGrid.ToggleEventListeners): New. Turns event listening on
863            and off so as to prevent excessive messages.
864            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
865            to suppress excessive messages when selecting many rows.
866            Fixes RTBug #1880.
867    
868            * Thuban/UI/view.py: Added checks against if scale == 0. This
869            is a serious problem that can occur when an image without
870            geo data is loading and causes the map projection bounds to
871            go to infinity. Right now, the solution is to simply try
872            to recover.
873    
874            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
875            to set the MFILEReceiver attributes even if the data is NULL.
876    
877            * extensions/thuban/gdalwarp.cpp: Improved the error handling
878            and passed GDAL messages back up to the Python layer. Also
879            tried to fix some memory leaks that were present in the original
880            utility but didn't matter because the program aborted.
881    
882            * test/test_range.py: Copied over tests from SciParam. Removed
883            tests against importing. Fixes RTBug #1867.
884    
885    2003-05-21  Bernhard Herzog  <[email protected]>
886    
887            * test/test_load.py: Remove unused imports and restructure the
888            test code
889            (LoadSessionTest): Split into one class for each test and turn
890            LoadSessionTest itself into the base class for all such session
891            tests.
892            (ClassificationTest): New base class for load tests that test
893            classifications
894            (TestSingleLayer, TestLayerVisibility, TestClassification)
895            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
896            for the individual tests
897    
898            * test/support.py (FileLoadTestCase.filename): New base class for
899            file loading tests
900    
901    2003-05-21  Jan-Oliver Wagner <[email protected]>
902    
903            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
904            Mercator' to 'UTM Zone 32' as a more convenient example.
905            Added 'Gauss Krueger Zone 6'.
906    
907            * Data/iceland_sample_raster.thuban: political polygon now
908            filled transparent to have the raster image visible at once.
909    
910    2003-05-21  Frank Koormann  <[email protected]>
911    
912            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
913            OnClose() to keep in sync with extensions. Internally Thuban
914            still uses "underscored" names.
915    
916    2003-05-20  Jonathan Coles   <[email protected]>
917    
918            This puts back Raster layer support. These layers support projections
919            through the GDAL library. Currently, the CVS version is being used.
920            There are no Debian packages available although this may change soon.
921            A GDAL driver was extended to support writing to memory rather to
922            files.
923    
924            There is still some work that needs to be done, such as some error
925            handling when loading invalid images or when there is a problem
926            projecting the image. This putback simply checks in the majority
927            of the work.
928    
929            * setup.py: Add gdalwarp library extension.
930    
931            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
932            Defaults to False, but can be overridden by subclasses if they
933            support classification.
934            (RasterLayer): New. Defines a new layer that represents an
935            image.
936    
937            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
938            tag handler.
939            (SessionLoader.start_layer): Encode the filename.
940            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
941            New. Supports reading a rasterlayer tag.
942    
943            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
944    
945            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
946            get a string in Latin1. If we get such as string convert it to
947            unicode first, otherwise leave if alone before encoding.
948            (SessionSaver.write_layer): Add support for writing both Layers
949            and RasterLayers.
950    
951            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
952            The right argument may not be a string, it could also be a Column.
953    
954            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
955            Make initial window size 600x400. Fixes RTBug #1872.
956    
957            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
958            the dialog is constructed so that we can support layers that
959            do not have classifications.
960            (Classifier._OnTry): Only build a classification if the layer
961            supports one.
962    
963            * Thuban/UI/legend.py: Change all checks that a layer is an
964            instance of Layer into checks against BaseLayer.
965            (LegendTree.__FillTreeLayer): Only add children to a branch if
966            the layer supports classification.
967    
968            * Thuban/UI/mainwindow.py (MainWindow.NewSession,
969            MainWindow.OpenSession): Don't proceed with an action if the
970            user chooses Cancel when they are asked to save changes.
971            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
972            user to select an image file. Create a new RasterLayer and add
973            it to the map.
974    
975            * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
976            for rendering RasterLayer layers.
977            (MapRenderer.draw_raster_layer): Actually method that calls
978            the GDALWarp python wrapper and constructs an image from the
979            data returned.
980    
981            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the
982            Choices symbols to match those used in the table query method.
983            Replace deprecated method calls on table with new method names.
984    
985            * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
986            how small the scale can get. This still needs more testing.
987    
988            * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
989            Provides a driver to output in .bmp format.
990    
991            * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h:
992            New. Provides IO routines which write to memory, rather than a file.
993    
994            * extensions/thuban/gdalwarp.cpp: New, but basically a direct copy
995            of the gdalwarp utility provided in GDAL. Added function calls
996            that can be accessed from python.
997    
998            * Data/iceland_sample_raster.thuban: New. Sample file that uses
999            a raster layer.
1000    
1001            * Data/iceland/island.tfw, Data/iceland/island.tif: New. Raster
1002            layer image data.

1005    
1006            * test/test_layer.py, test/test_load.py, test/test_save.py: Added
1007            tests associated with the raster layer code.
1008    
1009            * test/test_transientdb.py
1010            (TestTransientTable.test_auto_transient_table_query): Added a test
1011            for using a Column object as the "right" parameter to a query.
1012    
1013    2003-05-19  Frank Koormann  <[email protected]>
1014    
1015            * Thuban/version.py (get_changelog_date):
1016            Catch exceptions if ChangeLog does not exist.
1017    
1018            * Thuban/UI/view.py (MapCanvas.Export): Bugfix
1019    
1020    2003-05-19  Frank Koormann  <[email protected]>
1021    
1022            Extended version information for Thuban
1023    
1024            * Thuban/version.py: New, version information for Thuban: Last
1025            modification date and last ChangeLog entry date.
1026    
1027            * Thuban/UI/mainwindow.py (MainWindow.About()): Extended version
1028            information: Display Thuban, wxPython and Python version.
1029    
1030    2003-05-16  Bernhard Herzog  <[email protected]>
1031    
1032            * Thuban/Model/save.py: Remove some unused imports including the
1033            __future__ import for nested_scopes as Thuban relies on Python 2.2
1034            now.
1035            (XMLWriter.encode): Remove the special case for a None argument.
1036            In the saver encode is always called with a string argument.
1037    
1038    2003-05-16  Bernhard Herzog  <[email protected]>
1039    
1040            * Thuban/UI/__init__.py: Remove the work-around for the locale bug
1041            in wxPython (at least when usinvg wxGTK) prior to 2.4. The symptom
1042            of the bug was that e.g. float("1.2") would fail. Thuban now
1043            requires 2.4.x.
1044            
1045    2003-05-16  Frank Koormann   <[email protected]>
1046    
1047            Printing enhancement and WMF export (under Win32)
1048

1054            * Thuban/UI/view.py (MapPrintout.__init__): Enhanced parameter set
1055            to fullfil information needed for PrinterRenderer.
1056            (MapCanvas.Export): New. Export Map (currently only to WMF on Win32).
1057            (MapCanvas.Print): Adapted to new MapPrintout.
1058            (OutputTransform): General calculations to transform from canvas
1059            coordinates to export/printing devices.
1060    
1061            * Thuban/UI/mainwindow.py (MainWindow.ExportMap()): New. Added also
1062            new method_command to call ExportMap, with platform dependency (only

1064      
1065            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Position and Size
1066            of scalebar drawing area as new parameters.

1069    
1070            * Thuban/UI/legend.py (ScalebarBitmap.__SetScale):
1071            Update to extended scalebar.DrawScalebar header.
1072    
1073            * test/test_export.py: New, test Thuban.UI.view.OutputTransform()
1074    
1075            * test/test_scalebar.py: Made test executable as standalone.
1076    
1077    2003-05-16  Bernhard Herzog  <[email protected]>
1078    
1079            * Thuban/Model/table.py (Table): Remove this compatibility alias
1080            for DBFTable.
1081    
1082            * test/test_table.py: Import DBFTable as Table because that alias
1083            doesn't exist anymore.
1084    
1085            * Thuban/UI/classgen.py: Remove some unused imports
1086    
1087    2003-05-14  Jonathan Coles   <[email protected]>

1094            bounds of the generated classes.
1095    
1096            * Thuban/Model/range.py (Range.number_re): Now accepts floats that
1097            do not have a leading 0 (.5 is now accepted as well as 0.5).
1098    
1099            * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Fix name of method
1100            call to ClassGenerator.GenUniformDistribution.

1108    
1109    2003-05-12  Jonathan Coles   <[email protected]>
1110    
1111            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Replace call
1112            to table.UniqueValues() with calls that retrieve all the values
1113            from the table. This will need to be replaced by a method on table
1114            which can simply return the list (perhaps more efficiently).
1115    
1116    2003-05-12  Jonathan Coles   <[email protected]>
1117    
1118            The return value of ClassGenerator.CalculateQuantiles has changed.
1119            Refer to the documentation for details.
1120    
1121            * test/test_classgen.py: Modified Quantile tests to use the
1122            new return values.
1123    
1124            * Thuban/Model/classgen.py
1125            (ClassGenerator.GenQuantiles): Add comments describing the parameters,
1126            use new return values from CalculateQuantiles to produce the correct
1127            range bounds in the Classification.
1128            (ClassGenerator.CalculateQuantiles): Add more comments describing
1129            the return values and parameters. Make minor adjustments to improve
1130            the legibility of the code. Fix problem with adjusted not being set
1131            in most cases.
1132    
1133    2003-05-12  Frank Koormann <[email protected]>
1134            
1135            * Thuban/Model/save.py (XMLWriter.encode()): Explicite call to unicode
1136            and latin1. Fixes #1851 finally.
1137    
1138    2003-05-09  Jonathan Coles   <[email protected]>
1139    
1140            * test/test_classgen.py: New. Tests the Quantile algorithm.
1141    
1142            * Thuban/Model/classgen.py (ClassGenerator.CalculateQuantiles):

1147    
1148            Introduces Range class from SciParam into the ClassGroupRange class,
1149            and such ranges can now be saved and loaded from disk.
1150    
1151            Quantiles are now available in the Classification Generator.
1152    
1153            Initial support for building Queries on a table. Doesn't do anything
1154            but run some tests.
1155    
1156            * Thuban/Model/classification.py: Explicit imports.
1157            (ClassGroupRange): Use the Range class to store the underlying
1158            range information. The interface remains the same, except for
1159            GetRange(), and you can also supply a Range object as the min
1160            parameter to SetRange or __init__.
1161    
1162            * Thuban/Model/load.py (XMLReader.encode): New. Encodes the given
1163            string appropriately for use in Thuban. Fixes RTbug #1851.
1164            (SessionLoader.end_projection): Handle the context of the
1165            projection tag a bit better by looking at what objects are not
1166            None. There was an assumption that a projection tag for a map
1167            could occur before any layers.
1168            (SessionLoader.start_clrange): Provide backward compatibility for
1169            reading min/max values as well as the new range parameter.
1170    
1171            * Thuban/Model/map.py: Explicit imports.
1172    
1173            * Thuban/Model/resource.py: Import _.
1174            (ProjFileSaver.write): write header using projfile.dtd.
1175    
1176            * Thuban/Model/save.py: Explicit imports.
1177            (XMLWriter.encode): New. Encode the given string from a format
1178            used by Thuban into UTF-8. Fixes RTbug #1851.

1352            Convert all table users to use the new table interface. This only
1353            covers Thuban itself, not GREAT-ER or other applications built on

1467    
1468            Convert the table implementations to a new table interface. All
1469            tables use a common mixin class to provide backwards compatibility
1470            until all table users have been updated.
1471    
1472            * Thuban/Model/table.py (OldTableInterfaceMixin): Mixin class to

1484            with the new table interface.
1485    
1486            * test/test_table.py: Document the all tests in this file as only
1487            for backwards compatibility. The equivalent tests for the new
1488            interface are in test_memory_table.py and test_dbf_table.py
1489            (MemoryTableTest.test_read): field_info should be returning tuples
1490            with four items

1501            from OldTableInterfaceMixin for compatibility.
1502            (AutoTransientTable.write_record): Removed. It's not implemented
1503            yet and we still have to decide how to handle writing with the new
1504            table and data framework.
1505    
1506            * test/test_transientdb.py
1507            (TestTransientTable.run_iceland_political_tests)

1513            This is namely a collection of UI updates to improve user interactivity.
1514            Tabbing between controls now exists and you can use ESC to close dialog
1515            boxes; ENTER will active the default button.
1516    
1517            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Rearrange the
1518            order that the controls are created so that tabbing works correctly.
1519            (ClassGenDialog.OnOK): Renamed from _OnGenerate() so that the
1520            wxDialog can handle the default button correctly.
1521            (ClassGenDialog.OnCancel): Renamed from _OnCloseBtn() for the
1522            same reasons as for OnOK.

1524            when we ask the table for the maximum/minimum values of a field
1525            which could take a very long time.
1526    
1527            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange the
1528            order that the controls are created so that tabbing works correctly.

1531    
1532            * Thuban/UI/dialogs.py: Copied NonModalDialog box and changed it
1533            to derive from a wxDialog but behave like the original implementation
1534            which was derived from a wxFrame. wxDialog provides useful key
1535            handling functionality like ESC calling OnCancel and ENTER calling
1536            OnOK which is lost with wxFrame.
1537    
1538            * Thuban/UI/mainwindow.py: Add "..." to menu items that will open
1539            new dialogs.
1540

1542            order that the controls are created so that tabbing works correctly.
1543            (ProjFrame.OnApply): Renamed from _OnTry() to use wxDialog behaviour.
1544            (ProjFrame.OnOK): Renamed from _OnOK() to use wxDialog behaviour.
1545            (ProjFrame.OnCancel): Renamed from _OnClose() to use wxDialog behaviour.
1546            (ProjPanel.__init__): Add "Airy" to the list of ellipsoids so we
1547            can provide the "UK National Grid" as a default projection.
1548            (UTMPanel.__init__): Rearrange the order that the controls are
1549            created so that tabbing works correctly.
1550    
1551    2003-05-05  Bernhard Herzog  <[email protected]>
1552    
1553            * extensions/thuban/wxproj.cpp: Fix some of the comments.
1554            (project_point): If a map projection but no layer projection is

1556            projection.
1557    
1558            * Thuban/UI/tableview.py (TableGrid.disallow_messages)
1559            (TableGrid.allow_messages): New methods to make it possible to
1560            inhibit message sending.
1561            (TableGrid.issue): Only send the message if not inhibited.
1562            (LayerTableGrid.select_shape): Use the new methods to make sure
1563            that no ROW_SELECTED message is sent while we're updating the
1564            selected rows to match the selected shapes.
1565

1567    
1568            Implementation of MemoryTable.
1569    
1570            * Thuban/Model/table.py (MemoryTable): New. Quite simple table
1571            implementation that operates on a list of tuples. All of the data
1572            are kept in the memory.
1573    
1574            * test/test_table.py (MemoryTableTest): New.
1575    
1576            * test/test_transientdb.py (SimpleTable): Removed.
1577            (TestTransientTable.test_transient_joined_table,
1578            (TestTransientTable.test_transient_table_read_twice): Replaced
1579            SimpleTable by MemoryTable.
1580    
1581    2003-04-30  Jonathan Coles   <[email protected]>
1582    
1583            * Data/iceland_sample.thuban: Now contains correct projections
1584            for each of the layers.
1585    
1586            * Resources/Projections/defaults.proj: Geographic projection
1587            contains unit conversion parameter.
1588    
1589    2003-04-30  Jonathan Coles   <[email protected]>
1590    
1591            The most important part of this putback is the projection changes.
1592            It should now be possible to specify the projection that a layer
1593            is in and then specify a different projection for the map. The
1594            projection dialog has an extra parameter for a geographic projection
1595            which lets the user select if the input is in degrees or radians.
1596    
1597            * Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring
1598            to say that the parameter is a tuple of unprojected
1599            points (which is what the callers to this method were assuming).
1600            Also, since the points are unprojected we need to projected them.
1601    
1602            * Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp,
1603            LegendTree.MoveCurrentItemDown): If the layer or any of the layer's
1604            groups are selected, move the layer up/down. Fixes RTbug #1833.
1605    
1606            * Thuban/UI/mainwindow.py: Move menu item map_rename up.
1607    
1608            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing
1609            parameter in call to SetClientData.
1610            (GeoPanel): Add support for selecting the units that the
1611            source data is in (Radians or Degrees).
1612    
1613            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize
1614            the rendering loop by reducing the number of if's, removing the
1615            unnecessary try/except block, and checking if the old group
1616            is the same as the new one (which happens a lot if there is
1617            no classification, or lots of shapes are in the same group).
1618    
1619            * Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block
1620            around the redraw routine to try to catch problems that the user
1621            may create by selecting invalid projections for the data set and
1622            map. Clears the display if there are any problems and prints the
1623            error.
1624            (MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled
1625            rectangle.
1626    
1627            * extensions/thuban/wxproj.cpp (project_point): First invert the
1628            supplied point (which should be in projected coordinates) using
1629            the layer's projection and then project the point using the
1630            map's projection.
1631            (project_points): Use project_point() to project each point.
1632    
1633    2003-04-30  Jan-Oliver Wagner <[email protected]>
1634    
1635            * Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug:
1636            don't set the Classification to None if the classfication field
1637            is None (ie only a DEFAULT).
1638    
1639    2003-04-30  Bernhard Herzog  <[email protected]>
1640    
1641            * Thuban/UI/view.py: Fix some typos.
1642    
1643            * Thuban/UI/mainwindow.py (MainWindow.identify_view_on_demand): Do
1644            not pop up the dialog if the selection becomes empty (this could
1645            happen if e.g. a new selection is opened while the identify tool
1646            is active and dialog had been closed)
1647    
1648    2003-04-30  Bernhard Herzog  <[email protected]>
1649    
1650            * Thuban/Model/transientdb.py (TransientTableBase.__init__): New
1651            instance variable read_record_last_result
1652            (TransientTableBase.read_record): Make sure reading the same
1653            record twice works. The implementation uses the new instance
1654            variable read_record_last_result
1655    
1656            * test/test_transientdb.py
1657            (TestTransientTable.test_transient_table_read_twice): New test
1658            case for the above bug-fix.
1659    
1660    2003-04-29  Jonathan Coles   <[email protected]>
1661    
1662            * Thuban/common.py: Removed. No longer needed Str2Num. RTbug #1832.
1663    
1664            * Thuban/UI/classgen.py: Remove all uses of Str2Num.
1665    
1666            * Thuban/UI/classifier.py: Remove all uses of Str2Num.
1667            (ClassTable.SetValueAsCustom): Rename keyword argument in
1668            ClassGroup* constructors to match argument name.
1669    
1670    2003-04-29  Bernhard Herzog  <[email protected]>
1671    
1672            * Thuban/Model/session.py (Session.Destroy): Explicitly close the
1673            transient DB if it exists to make sure it doesn't leave a journal
1674            file in the temp directory.
1675    
1676            * Thuban/Model/transientdb.py (TransientDatabase.close): Set
1677            self.conn to None after closing the connection to make sure it's
1678            not closed twice
1679    
1680    2003-04-29  Jonathan Coles   <[email protected]>
1681    
1682            Add a visible parameter in the layer XML tag. The default value is
1683            "true". If anything other than "false" is specified we also assume
1684            "true". Addresses RTbug #1025.
1685    
1686            * Doc/thuban.dtd: Add visible parameter to a layer.
1687    
1688            * Thuban/Model/layer.py (BaseLayer.__init__): Change default value
1689            of visible from 1 to True.
1690            (Layer.__init__): Change default value of visible from 1 to True.
1691    
1692            * Thuban/Model/load.py (SessionLoader.start_layer): Read visible
1693            parameter.
1694    
1695            * Thuban/Model/save.py (SessionSaver.write_layer): Save visible
1696            parameter.
1697    
1698            * test/test_load.py: Add new test data contents_test_visible.
1699            (LoadSessionTest.setUp): save test data.
1700            (LoadSessionTest.testLayerVisibility): Test if the visible flag
1701            is loaded correctly.
1702    
1703            * test/test_save.py (SaveSessionTest.testSingleLayer): Add test
1704            for saving an invisible layer.
1705    
1706    2003-04-29  Jonathan Coles   <[email protected]>
1707    
1708            * Thuban/UI/mainwindow.py (MainWindow.SetMap): Look up the
1709            legend dialog box and tell it to change its map to the one
1710            supplied to SetMap(). Fixes RTbug #1770.
1711    
1712    2003-04-29  Bernhard Herzog  <[email protected]>
1713    
1714            Next step of table implementation. Introduce a transient database
1715            using SQLite that some of the data is copied to on demand. This
1716            allows us to do joins and other operations that require an index
1717            for good performance with reasonable efficiency. Thuban now needs
1718            SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I
1719            haven't tested that.
1720            
1721            * Thuban/Model/transientdb.py: New. Transient database
1722            implementation.
1723    
1724            * test/test_transientdb.py: New. Tests for the transient DB
1725            classes.
1726    
1727            * Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New
1728            classes to help automatically remove temporary files and
1729            directories.
1730            (Session.__init__): New instance variables temp_dir for the
1731            temporary directory and transient_db for the SQLite database
1732            (Session.temp_directory): New. Create a temporary directory if not
1733            yet done and return its name. Use AutoRemoveDir to have it
1734            automatically deleted
1735            (Session.TransientDB): Instantiate the transient database if not
1736            done yet and return it.
1737    
1738            * Thuban/Model/data.py (ShapefileStore.__init__): Use an
1739            AutoTransientTable so that data is copied to the transient DB on
1740            demand.
1741            (SimpleStore): New class that simply combines a table and a
1742            shapefile
1743    
1744            * Thuban/Model/table.py (Table, DBFTable): Rename Table into
1745            DBFTable and update its doc-string to reflect the fact that this
1746            is only the table interface to a DBF file. Table is now an alias
1747            for DBFTable for temporary backwards compatibility.
1748    
1749            * Thuban/UI/application.py (ThubanApplication.OnExit): Make sure
1750            the last reference to the session goes away so that the temporary
1751            files are removed properly.
1752    
1753            * test/test_load.py (LoadSessionTest.tearDown): Remove the
1754            reference to the session to make sure the temporary files are
1755            removed.
1756    
1757    2003-04-29  Bernhard Herzog  <[email protected]>
1758    
1759            * Thuban/Model/load.py (XMLReader.__init__, XMLReader.read): Turn
1760            the __parser instance variable into a normal local variable in
1761            read. It's only used there and read will never be called more than
1762            once. Plus it introduces a reference cycle that keeps can keep the
1763            session object alive for a long time.
1764    
1765    2003-04-29  Jonathan Coles   <[email protected]>
1766    
1767            * Thuban/Model/proj.py (Projection): Removed Set*() methods to make
1768            Projection an immutable item. Fixes RTbug #1825.
1769            (Projection.__init__): Initialize instance variables here.
1770            (ProjFile.Replace): New. Replace the given projection object with
1771            the new projection object. This solves the problem of needing the
1772            mutator Projection.SetProjection() in the ProjFrame class and
1773            allows a projection to change parameters without changing its
1774            location in the file.
1775    
1776            * Thuban/UI/mainwindow.py (MainWindow.SaveSessionAs): Dialog should
1777            be of type wxSAVE and should verify overwriting a file.
1778    
1779            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Use the new
1780            ProjFile.Replace() method instead of the mutator
1781            Projection.SetProjection(). Also requires that we reassign the
1782            client data to the new projection.
1783    
1784            * test/test_proj.py (TestProjection.test): Test GetName() and
1785            GetAllParameters()
1786            (TestProjFile.test): Remove tests for Set*() methods. Add tests
1787            for Replace().
1788    
1789    2003-04-25  Jonathan Coles   <[email protected]>
1790    
1791            * Thuban/Model/save.py (SessionSaver.write_projection): Make sure
1792            to save the name of the projection.
1793    
1794            * test/test_save.py (SaveSessionTest.testLayerProjection): New
1795            test to verify layer projections are saved correctly.
1796    
1797    2003-04-25  Jonathan Coles   <[email protected]>
1798    
1799            * Thuban/Model/proj.py (Projection.SetName): Set the name
1800            to "Unknown" if name is None.
1801            (Projection.SetAllParameters): New. Set the projection's
1802            parameter list to the one supplied.
1803            (Projection.SetProjection): New. Set the projection's
1804            properties to those of the supplied Projection.
1805    
1806            * Thuban/UI/mainwindow.py (MainWindow.MapProjection): Set
1807            the dialog title to include the map's title.
1808            (MainWindow.LayerProjection): Set the dialog title to include
1809            the layer's title.
1810    
1811            * Thuban/UI/projdialog.py (ProjFrame.__ShowError): Consolidate
1812            error dialogs into a single method call.
1813            (ProjFrame.__VerifyButtons): Add more states to check.
1814            (ProjFrame.__GetProjection): Return the current state of an
1815            edited projection or None.
1816            (ProjFrame.__FillAvailList): Remove checks for states that
1817            shouldn't exist.
1818            (ProjFrame._OnNew): Clear all selected items and supply
1819            a projection panel if necessary.
1820    
1821            * test/test_proj.py (TestProjFile.test): Add tests for
1822            ProjFile.SetAllParameters, ProjFile.SetProjection,
1823            ProjFile.SetName.
1824    
1825    2003-04-25  Jonathan Coles   <[email protected]>
1826    
1827            * Thuban/UI/projdialog.py (ProjFrame.__FillAvailList): Now
1828            takes an optional argument to select the current projection.
1829            This does not guarantee that the item is visible due to
1830            limited wxWindows functionality. Fixes RTBug #1821.
1831    
1832    2003-04-25  Jonathan Coles   <[email protected]>
1833    
1834            * Thuban/Model/load.py (SessionLoader.start_projection): Remember
1835            the projection name and use it when constructing the Projection
1836            object.
1837    
1838            * Thuban/Model/proj.py (Projection.__init__): Change the default
1839            value for 'name' to None and then test if name is equal to None
1840            in the body of the constructor. This way the caller doesn't have to
1841            know what the default value should be. Namely, useful in load.py
1842            where we have to pick a default value if the 'name' parameter
1843            doesn't exist in the XML file.
1844    
1845            * test/test_load.py (LoadSessionTest.testLayerProjection): New.
1846            Tests a file where a layer has a projection.
1847    
1848    2003-04-25  Jonathan Coles   <[email protected]>
1849    
1850            * Thuban/Model/layer.py (Layer.TreeInfo): Add an item to the
1851            tree for projection information.
1852    
1853            * Thuban/Model/load.py (XMLReader.GetFilename): Renamed from
1854            XMLReader.GetFileName.
1855            (SessionLoader): Added support for loading projection tags that
1856            appear inside a layer.
1857    
1858            * Thuban/Model/proj.py (ProjFile): Document the class. Move
1859            back to using a list because the order of the projections in
1860            the file is important to maintain. Fixes RTbug #1817.
1861    
1862            * Thuban/Model/resource.py: Rename calls to ProjFile.GetFileName
1863            to ProjFile.GetFilename.
1864    
1865            * Thuban/Model/save.py (SessionSaver.write_layer): Save projection
1866            information.
1867    
1868            * Thuban/UI/projdialog.py (ProjFrame._OnAddToList): Renamed from
1869            ProjFrame._OnSaveAs. Removed old dead code from previous
1870            implementation.
1871            (ProjFrame._OnExport): Add support for exporting more than one
1872            projection to a single file.
1873            (ProjFrame.__FillAvailList): use string formatting (% operator)
1874            to build strings that are (partly) translated. Fixes RTbug #1818.
1875    
1876            * test/test_proj.py (TestProjFile.test): New. Tests the base ProjFile
1877            class.
1878    
1879    2003-04-24  Bernhard Herzog  <[email protected]>
1880    
1881            * po/es.po: Updated Spanish translation by Daniel Calvelo Aros
1882    
1883            * po/fr.po: New. French translation by Daniel Calvelo Aros
1884    
1885            * Thuban/UI/projdialog.py (ProjFrame._OnSaveAs): Don't translate
1886            empty strings.
1887    
1888    2003-04-24  Jonathan Coles   <[email protected]>
1889    
1890            * Thuban/Model/layer.py (Layer.GetProjection): New. Needed to
1891            implement the interface that the ProjFrame dialog expects.
1892    
1893            * Thuban/Model/proj.py (Projection.SetName): New. Allows the
1894            name of the projection to be changed.
1895            (ProjFile): Use a dictionary instead of a list so that removing
1896            projections is easier and we are sure about uniqueness.
1897            (ProjFile.Remove): Remove the given projection object.
1898    
1899            * Thuban/Model/resource.py (GetSystemProjFiles, GetUserProjFiles):
1900            Return a list with only one projection file instead of searching for
1901            any projection file. This simplifies many things if the user can
1902            only have one system file and one user file.
1903    
1904            * Thuban/UI/classgen.py: Change all references to
1905            genCombo to genChoice.
1906    
1907            * Thuban/UI/mainwindow.py: Add a Projection option under the
1908            layer menu.
1909            (MainWindow.LayerProjection): New. Open up a projection window
1910            for a layer.
1911    
1912            * Thuban/UI/projdialog.py: Large changes to how the dialog is
1913            laid out. Use three panels instead of one. One for the list of
1914            projections, one for the edit controls, and one for the buttons.
1915            Fixed resizing problems so that the dialog resizes correctly
1916            when the projection panel changes. Added import/export, save, and
1917            new buttons/functionality.
1918    
1919    2003-04-24  Bernhard Herzog  <[email protected]>
1920    
1921            First step towards table management. Introduce a simple data
1922            abstraction so that we replace the data a layer uses more easily
1923            in the next step.
1924    
1925            * Thuban/Model/data.py: New file with a simple data abstraction
1926            that bundles shapefile and dbffile into one object.
1927    
1928            * Thuban/Model/session.py (Session.OpenShapefile): New method to
1929            open shapefiles and return a shape store object
1930    
1931            * Thuban/Model/layer.py (Layer.__init__): Pass the data as a store
1932            object instead of a shapefile filename. This introduces a new
1933            instance variable store holding the datastore. For intermediate
1934            backwards compatibility keep the old instance variables.
1935            (open_shapefile): Removed. No longer needed with the shape store.

2316    2003-04-10  Jonathan Coles   <[email protected]>
2317    
2318            * Thuban/Model/classification.py: (ClassGroupRange.__init__):
2319            Should pass group to ClassGroup constructor.
2320    
2321    2003-04-10  Jonathan Coles   <[email protected]>
2322    
2323            * Thuban/Model/classification.py: (ClassGroup): Move all the common
2324            methods of the derived classes ([Set|Get]Properties(), __eq__, __ne__)
2325            here. Implement SetVisible(), IsVisible().
2326            (ClassGroup.__init__): Add group parameter which acts as a copy
2327            constructor.
2328    
2329            * Thuban/UI/classifier.py (ClassTable): Add a new column for the
2330            "Visible" check boxes.

2332            the new labels.
2333    
2334            * Thuban/UI/legend.py: Classify button is now called "Properties".
2335            Refactored the code to change variable names.

2340            renamed to MainWindow.LayerEditProperties.
2341            (MainWindow.ToggleLegend): Don't include map name in legend title.
2342            (MainWindow.SetMap): Added the map name to the window title.
2343            (MainWindow.LayerFillColor, MainWindow.LayerTransparentFill,
2344            MainWindow.LayerOutlineColor, MainWindow.LayerNoOutline): Removed.
2345            Functionality is found in the layer properties dialog.
2346    
2347            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
2348            draw visible groups.
2349    
2350    2003-04-09  Jonathan Coles   <[email protected]>
2351    
2352            * Thuban/UI/classgen.py: Modifications to allow simple
2353            addition and selection of new color schemes.
2354            (MonochromaticRamp): New. Generates a ramp between two colors.
2355            (RedRamp): New. Generates a ramp of all red.
2356            (GreenRamp): New. Generates a ramp of all green.
2357            (BlueRamp): New. Generates a ramp of all blue.
2358    
2359    2003-04-09  Jonathan Coles   <[email protected]>
2360    
2361            * Thuban/Model/classification.py (Classification.__deepcopy__):
2362            Need to copy over field and fieldType attributes.
2363    
2364            * Thuban/Model/table.py (Table.field_range): New. Retrive the
2365            maximum and minimum values over the entire table for a given
2366            field.
2367            (Table.GetUniqueValues): New. Retrieve all the unique values
2368            in the table for a given field.
2369    
2370            * Thuban/UI/classgen.py: Renamed GenRangePanel to GenUniformPanel.
2371            (GenUniquePanel): New. Controls to allow the user to select
2372            which unique field values they would like in the classification.
2373            (CustomRampPanel): Code that was in ClassGenDialog that allows
2374            the user to select the properties for a custom ramp.
2375            (ClassGenerator.GenUniformDistribution): Was called GenerateRanges.
2376    
2377            * Thuban/UI/classifier.py: Removed a lot of debugging code.
2378            (Classifier._SetClassification): Callback method so that the
2379            class generator can set the classification in the grid.
2380            (ClassGroupPropertiesCtrl): New. Encapsulates the drawing and
2381            editing of a group properties class into a wxWindows control.
2382    
2383            * Thuban/UI/dock.py: It was decided that if the user closes
2384            a dockable window the window should simply hide itself. That
2385            way if the user wants to show the dock again it appears in the
2386            same place as it was when it was closed.
2387            (DockableWindow.Destroy): Call renamed method OnDockDestroy().
2388            (DockableWindow._OnButtonClose): Hide the window instead of

2390            (DockableWindow._OnClose): Hide the window instead of
2391            destroying it.
2392    
2393            * Thuban/UI/legend.py (LegendTree): Use a private method to

2399    
2400            * Thuban/UI/mainwindow.py (main_menu): Move the toggle_legend item
2401            to the map module
2402    
2403    2003-04-07  Bernhard Herzog  <[email protected]>

2405            * Thuban/UI/mainwindow.py (MainWindow.ShowSessionTree): Removed in
2406            favor of ToggleSessionTree
2407            (MainWindow.ToggleSessionTree): New method to toggle visibility of
2408            the session tree.
2409            (MainWindow.SessionTreeShown): New method to return whether the
2410            session tree is currently shown.
2411            (MainWindow.ToggleLegend): New method to toggle visibility of the
2412            legend
2413            (MainWindow.ShowLegend): Implement in terms of ToggleLegend and
2414            LegendShown
2415            (MainWindow.LegendShown): New method to return whether the legend
2416            is currently shown.
2417            (_method_command): Add checked parameter so we can define check
2418            menu items
2419            (_has_tree_window_shown, _has_legend_shown): Use the appropriate
2420            mainwindow methods.
2421            (show_session_tree, show_legend commands): Removed.
2422            (toggle_session_tree, toggle_legend commands): New commands to
2423            toggle the visibility of the dialogs
2424    
2425    2003-04-07  Jonathan Coles   <[email protected]>
2426    
2427            * Thuban/UI/classgen.py: Fix Windows problem.
2428    
2429            * Thuban/UI/dock.py: Fix Windows problem.
2430    
2431            * Thuban/UI/mainwindow.py: Use False instead of false.
2432            (MainWindow.ShowLegend): Remove unnecessary switch parameter.
2433    
2434    2003-04-07  Jonathan Coles   <[email protected]>
2435    
2436            Since we now say that the order of the groups in a classification
2437            matters, it makes sense to be able to manipulate that order. Most
2438            of the changes to Thuban/Model/classification.py are to that end.
2439    
2440            * Thuban/Model/classification.py (Classification.AppendGroup,
2441            Classification.InsertGroup, Classification.ReplaceGroup,
2442            Classification.RemoveGroup, Classification.GetGroup): Do as the
2443            names imply.
2444            (Classification.FindGroup): This was called GetGroup, but GetGroup
2445            takes an index, while FindGroup takes a value.
2446            (Classification.__deepcopy__): Copy all the groups, BUT NOT THE LAYER
2447            REFERENCE. Currently there is a cyclic reference between the layer
2448            and its classification. If the classification doesn't need to know
2449            its owning layer we can change this, since it may make sense to be
2450            able to use the same classification with different layers.
2451    
2452            * Thuban/Model/load.py: Use Classification.AppendGroup(), not AddGroup()
2453    
2454            * Thuban/UI/classgen.py: Use Classification.AppendGroup(),
2455            not AddGroup()
2456    
2457            * Thuban/UI/classifier.py: Now that we can depend on the order in
2458            a Classification and have methods to manipulate that order we don't
2459            need to use our own data structures in the grid. We can simply make
2460            the grid/table access the information they need from a copy of
2461            the classification object.
2462            (Classifier._OnCloseBtn): Event handler for when the user clicks
2463            'Close'. This is needed so if the user applies changes and then
2464            continues to change the table the user has the option of discarding
2465            the most recent changes and keeping what they applied.
2466    
2467            * Thuban/UI/mainwindow.py: Put "Show Legend" and "Show Session Tree"
2468            into the same group.
2469    
2470            * extensions/thuban/wxproj.cpp (check_version): If Thuban is compiled
2471            with a really old version of proj, PJ_VERSION won't even be defined.
2472            If it isn't defined then just compile so that the function always
2473            returns Py_False.
2474    
2475            * test/test_classification.py: Fix tests to use the renamed methods.
2476            Still need to write tests for the new methods.
2477    
2478    2003-04-04  Jonathan Coles   <[email protected]>
2479    
2480            * Thuban/UI/classifier.py (Classifier.__SelectField): Move the
2481            call to SetSelection out of the method and before the call
2482            to __SelectField in __init__. This prevents a recursion of events
2483            when _OnFieldSelect is triggered by the user.
2484    
2485    2003-04-04  Jonathan Coles   <[email protected]>
2486    
2487            * Thuban/Model/classification.py: Rename Color.None to
2488            Color.Transparent.
2489            (ClassGroupProperties.SetLineColori, ClassGroupProperties.SetFill):
2490            Don't bother copying the color, since Colors are immutable.
2491    
2492            * Thuban/Model/color.py, Thuban/Model/layer.py, Thuban/Model/load.py,
2493            Thuban/UI/classifier.py, Thuban/UI/mainwindow.py,
2494            Thuban/UI/renderer.py, Thuban/UI/view.py:
2495            Rename Color.None to Color.Transparent.
2496        
2497            * test/test_classification.py, test/test_load.py: Rename Color.None
2498            to Color.Transparent.
2499    
2500    2003-04-04  Jonathan Coles   <[email protected]>
2501    
2502            * Thuban/Model/classification.py: Fix assert calls.
2503            (ClassGroupProperties.SetLineColor, ClassGroupProperties.SetFill):
2504            Copy the color parameter rather than hold onto a reference.
2505    
2506            * Thuban/Model/color.py (Color.__copy__, Color.__deepcopy): Copy
2507            the color object.
2508            (NoColor.__copy__, NoColor.__deepcopy): Return 'self' so that we
2509            are sure there exists only one refernce to Color.None in the system.
2510            This allows us to use 'is' rather than the comparision functions.
2511            
2512            * Thuban/Model/save.py: Fix assert calls.
2513            
2514            * Thuban/UI/classifier.py: Fix assert calls.
2515            (ClassGrid._OnCellDClick): Call up to the classifier to open the
2516            dialog to edit the groups properties.
2517            (ClassGrid._OnCellResize): Make sure that the scollbars are drawn
2518            correctly if a cell is resized.
2519            (ClassTable.SetClassification): New. Changes the classification
2520            that is in the table.
2521            (ClassTable.__SetRow): Allow groups to be prepended.
2522            (Classifier): New code for opening the EditProperties and
2523            GenerateRanges dialogs.
2524            (SelectPropertiesDialog.__GetColor): Only set the color in the
2525            color dialog if the current color is not None.
2526            
2527            * Thuban/UI/dock.py: Fix assert calls.
2528            
2529            * Thuban/UI/legend.py: Fix assert calls.
2530            
2531            * Thuban/UI/renderer.py: Fix assert calls.
2532            
2533            * Thuban/UI/classgen.py (ClassGenDialog): Dialog for generating
2534            classifications.
2535            (GenRangePanel): Panel specific to range generation.
2536            (GenSingletonPanel): Panel specific to singleton generation.
2537            (ClassGenerator): Class responsible for actually generating
2538            the classification from the data gathered in the dialog box.
2539            (PropertyRamp): Generates properties whose values range from
2540            a starting property to an ending property.
2541    
2542    2003-04-03  Bernhard Herzog  <[email protected]>
2543    
2544            * test/support.py (print_garbage_information): New function that
2545            prints information about still connected messages and memory
2546            leaks.
2547            (run_suite): Removed.
2548            (run_tests): New function for use as a replacement of
2549            unittest.main in the test_* files. This one calls
2550            print_garbage_information at the end.
2551    
2552            * test/runtests.py (main): Use support.print_garbage_information
2553    
2554            * test/test_layer.py: Use support.run_tests instead of
2555            unittest.main so we get memory leak information
2556            (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
2557            (TestLayer.test_point_layer, TestLayer.test_empty_layer)
2558            (TestLayerLegend.test_visibility): Call the layer's Destroy method
2559            to fix a memory leak.
2560    
2561            * test/test_classification.py: Use support.run_tests instead of
2562            unittest.main so we get memory leak information
2563            (TestClassification.test_classification): Call the layer's Destroy
2564            method to fix a memory leak.
2565    
2566    2003-04-02  Bernhard Herzog  <[email protected]>
2567    
2568            * extensions/thuban/wxproj.cpp (check_version, check_version_gtk):
2569            Handle the reference counts of the return value and errors in
2570            PyArg_ParseTuple correctly.
2571    
2572            * Thuban/UI/application.py (ThubanApplication.OpenSession): Make
2573            sure the filename is absolute to avoid problems when saving the
2574            session again
2575    
2576            * Thuban/Model/table.py: Remove unnecessary import. Fix a typo.
2577    
2578    2003-04-01  Jonathan Coles   <[email protected]>
2579    
2580            *  Thuban/UI/renderer.py (MapRenderer.draw_point_shape): Check
2581            that there actually are points in the returned list of points
2582            before trying to index into the list. The list may be empty if
2583            the shape is a Null Shape.
2584    
2585    2003-04-01  Bernhard Herzog  <[email protected]>
2586    
2587            * test/test_map.py: Don't use from <module> import *
2588    
2589    2003-04-01  Jonathan Coles   <[email protected]>
2590    
2591            * Thuban/Model/session.py: Use LAYER_CHANGED instead of
2592            LAYER_LEGEND_CHANGED
2593    
2594            * Thuban/UI/dock.py (DockableWindow._OnButtonClose): Call
2595            self.Destroy() to close the window after yesterday's changes.
2596    
2597            * test/test_map.py, test/test_session.py: Fix messages that
2598            are sent from maps and layers.
2599

2605    
2606            * Thuban/UI/dock.py (DockableWindow.UnDock): Restore size and
2607            position (although position doesn't work yet under GTK).
2608            (DockableWindow.Destroy): New. Called when the window must be
2609            closed. Namely needed when the DockFrame closes and must close
2610            its children.

2612    
2613            * Thuban/UI/legend.py (LegendPanel.Destroy): New. Cleans up
2614            when then window is told to close.

2618            * Thuban/UI/main.py: Show the legend by default when Thuban starts.
2619    
2620            * Thuban/UI/mainwindow.py: Renamed OnClose to _OnClose for
2621            symmetry with other such methods.
2622            (MainWindow.ShowLegend): Show the legend docked by default.
2623    
2624    2003-03-28  Jonathan Coles   <[email protected]>
2625    
2626            * Thuban/UI/classifier.py: Support for highlighting a specific
2627            group within the grid when the classification dialog is opened.
2628            Also contains a lot of debugging printouts which will later
2629            be removed.
2630    
2631            * Thuban/UI/dock.py: Complete rework on the dock code so that
2632            that it is fairly removed from the rest of the Thuban application.
2633            It is easy to add new docks which the rest of the program having
2634            to be aware of them.
2635    
2636            * Thuban/UI/legend.py: Modifications to support selecting a
2637            specific group in the classification dialog. Changed how layers
2638            are drawn when the layer is visible/invisible.
2639    
2640            * Thuban/UI/mainwindow.py: Removed legend specific code and
2641            replaced it with calls to the new dock code.
2642    
2643            * Thuban/UI/renderer.py (MapRenderer.__init__): Added assert
2644            to check if scale > 0. Trying to track down a divide by zero.
2645    
2646    2003-03-26  Jonathan Coles   <[email protected]>
2647    
2648            * Thuban/UI/legend.py: Removed unnecessary LegendDialog class.
2649            (LegendPanel): Removed _OnDock()/_OnUnDock() methods which are
2650            now part of DockableWindow.

2652            map.
2653            (LegendTree._OnSelChanged): Call LegendPanel.DoOnSelChanged()
2654            with the selected layer and/or group.
2655    
2656    2003-03-26  Jonathan Coles   <[email protected]>
2657    
2658            This putback contains the code for dockable windows. There is
2659            no support in wxWindows as of this date for windows that can
2660            attach themselves to other windows.
2661    
2662            The current model contains a DockableWindow which has a parent
2663            window for when it is detached and a dock window that it puts
2664            its contents in when it is docked. The contents of a DockableWindow
2665            must be a DockPanel. DockPanel itself derives from wxPanel.
2666    
2667            * Thuban/Model/layer.py (Layer.ClassChanged): Send a LAYER_CHANGED
2668            message, not a LAYER_LEGEND_CHANGED message.
2669    
2670            * Thuban/Model/map.py (Map): Forward LAYER_CHANGED messages.
2671    
2672            * Thuban/UI/classifier.py (Classifier.__init__): Use wxADJUST_MINSIZE
2673            as one of the style properties for the fieldTypeText item to
2674            be sure that its size is correct when the text changes.
2675    
2676            * Thuban/UI/dock.py: New. Classes for the DockPanel and
2677            DockableWindow.
2678    
2679            * Thuban/UI/legend.py: Added some more buttons and made the
2680            LegendPanel a DockPanel.
2681    
2682            * Thuban/UI/mainwindow.py: Added sash windows to the main window
2683            and supporting functions for manipulating the sashes.
2684            (MainWindow.ShowLegend): Create a DockableWindow with the
2685            LegendPanel as the contents.

2691    
2692    2003-03-25  Jonathan Coles   <[email protected]>
2693    
2694            * setup.py: Added custom script bdist_rpm_build_script so that
2695            when the rpm is built the path to wx-config is correct.
2696    
2697            * setup.cfg: Added line saying to use the custom build script
2698    
2699    2003-03-20  Jonathan Coles   <[email protected]>
2700    
2701            Initial implementation of the Legend.
2702    
2703            * Thuban/UI/legend.py: New. Creates a window that shows the map's
2704            Legend information and allows the user to add/modify classifications
2705            and how the layers are drawn on the map.
2706    
2707            * setup.py: New command 'build_docs' which currently uses
2708            happydoc to generate html documentation for Thuban.
2709    
2710            * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
2711            Returns a string which is appropriately describes the group.
2712    
2713            * Thuban/Model/layer.py (Layer.SetClassification): Generate a
2714            LAYER_CHANGED event instead of a LAYER_LEGEND_CHANGED event.
2715    
2716            * Thuban/Model/map.py (Map): Rename messages and use new, more
2717            specific, messages.
2718    
2719            * Thuban/Model/messages.py: New message to indicate that a layer's
2720            data has changed (LAYER_CHANGED). New map messages to indicate
2721            when layers have been added/removed/changed or if the stacking order
2722            of the layers has changed.
2723    
2724            * Thuban/Model/session.py: Rename and use new messages.
2725    
2726            * Thuban/UI/classifier.py: Remember if any changes have actually
2727            been applied so that if the dialog is cancelled without an application
2728            of changes we don't have to set a new classification.
2729            (ClassDataPreviewer): Pulled out the window specific code and put it
2730            ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
2731            symbols on any DC.

2749    
2750            * test/test_command.py: Run the tests when the module is run as a
2751            script
2752    
2753    2003-03-14  Bernhard Herzog  <[email protected]>
2754    
2755            Implement selection of multiple selected shapes in the same layer:
2756    
2757            - Introduce a new class to hold the selection. This basically
2758              replaces the interactor which was nothing more than the
2759              selection anyway. A major difference is of course that the new
2760              selection class supports multiple selected shapes in one layer
2761            
2762            - Move the object that represents the selection from the
2763              application to the canvas. The canvas is a better place than the
2764              application because the selection represents which shapes and
2765              layer of the map displayed by the canvas are selected and
2766              affects how the map is drawn.
2767    
2768            - Make the selection and its messages publicly available through
2769              the mainwindow.
2770    
2771            - The non-modal dialogs do not get a reference to the interactor
2772              anymore as they can simply refer to their parent, the
2773              mainwindow, for the what the interactor had to offer.
2774    
2775            * Thuban/UI/selection.py: New module with a class to represent the
2776            selection.
2777    
2778            * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
2779            these unused messages
2780    
2781            * Thuban/UI/application.py (ThubanApplication.OnInit)
2782            (ThubanApplication.OnExit, ThubanApplication.SetSession): The
2783            interactor is gone now.
2784            (ThubanApplication.CreateMainWindow): There is no interactor
2785            anymore so we pass None as the interactor argument for now for
2786            compatibility.
2787    
2788            * Thuban/UI/view.py (MapCanvas.delegated_messages)
2789            (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
2790            Unsubscribe, delegate messages according to the delegated_messages
2791            class variable.
2792            (MapCanvas.__getattr__, MapCanvas.delegated_methods): Get some
2793            attributes from instance variables as described with the
2794            delegated_methods class variable.
2795            (MapCanvas.__init__): New instance variable selection holding the
2796            current selection
2797            (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
2798            pass them on to the renderer
2799            (MapCanvas.SetMap): Clear the selection when a different map is
2800            selected.
2801            (MapCanvas.shape_selected): Simple force a complete redraw. The
2802            selection class now takes care of only issueing SHAPES_SELECTED
2803            messages when the set of selected shapes actually does change.
2804            (MapCanvas.SelectShapeAt): The selection is now managed in
2805            self.selection
2806    
2807            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
2808            (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
2809            Unsubscribe, delegate messages according to the delegated_messages
2810            class variable.
2811            (MainWindow.delegated_methods, MainWindow.__getattr__): Get some
2812            attributes from instance variables as described with the
2813            delegated_methods class variable.
2814            (MainWindow.__init__): The interactor as ivar is gone. The
2815            parameter is still there for compatibility. The selection messages
2816            now come from the canvas.
2817            (MainWindow.current_layer, MainWindow.has_selected_layer):
2818            Delegate to the the canvas.
2819            (MainWindow.LayerShowTable, MainWindow.Classify)
2820            (MainWindow.identify_view_on_demand): The dialogs don't need the
2821            interactor parameter anymore.
2822    
2823            * Thuban/UI/tableview.py (TableFrame.__init__)
2824            (LayerTableFrame.__init__, LayerTableFrame.OnClose)
2825            (LayerTableFrame.row_selected): The interactor is gone. It's job
2826            from the dialog's point of view is now done by the mainwindow,
2827            i.e. the parent. Subscribe to SHAPES_SELECTED instead
2828            of SELECTED_SHAPE
2829            
2830            * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
2831            is gone. It's job from the dialog's point of view is now done by
2832            the mainwindow, i.e. the parent.
2833            
2834            * Thuban/UI/classifier.py (Classifier.__init__): The interactor is
2835            gone. It's job from the dialog's point of view is now done by the
2836            mainwindow, i.e. the parent.
2837    
2838            * Thuban/UI/tree.py (SessionTreeView.__init__): The interactor is
2839            gone. It's job from the dialog's point of view is now done by the
2840            mainwindow, i.e. the parent.
2841            (SessionTreeCtrl.__init__): New parameter mainwindow which is
2842            stored as self.mainwindow. The mainwindow is need so that the tree
2843            can still subscribe to the selection messages.
2844            (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
2845            (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
2846            selection is now accessible through the mainwindow. Subscribe to
2847            SHAPES_SELECTED instead of SELECTED_SHAPE
2848    
2849            * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
2850            SHAPES_SELECTED message now.
2851            (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
2852            so deal with multiple shapes
2853            (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
2854            gone. It's job from the dialog's point of view is now done by the
2855            mainwindow, i.e. the parent.
2856    
2857            * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
2858            parameter is now a list of shape ids.
2859            (RecordTable.SetTable): The second parameter is now a list of
2860            indices.
2861    
2862            * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the
2863            selected_shape parameter and ivar to selected_shapes. It's now a
2864            list of shape ids.
2865            (MapRenderer.draw_label_layer): Deal with multiple selected
2866            shapes. Rearrange the code a bit so that the setup and shape type
2867            distinctions are only executed once.
2868    
2869            * test/test_selection.py: Test cases for the selection class
