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

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.

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.

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
