2    
3            * Thuban/Model/transientdb.py (TransientTableBase.__init__): New
4            instance variable read_record_last_result
5            (TransientTableBase.read_record): Make sure reading the same
6            record twice works. The implementation uses the new instance
7            variable read_record_last_result
8    
9            * test/test_transientdb.py
10            (TestTransientTable.test_transient_table_read_twice): New test
11            case for the above bug-fix.
12    
13    2003-04-29  Bernhard Herzog  <[email protected]>
14    
15            * Thuban/Model/session.py (Session.Destroy): Explicitly close the
16            transient DB if it exists to make sure it doesn't leave a journal
17            file in the temp directory.
18    
19            * Thuban/Model/transientdb.py (TransientDatabase.close): Set
20            self.conn to None after closing the connection to make sure it's
21            not closed twice
22    
23    2003-04-29  Jonathan Coles   <[email protected]>
24    
25            Add a visible parameter in the layer XML tag. The default value is
26            "true". If anything other than "false" is specified we also assume
27            "true". Addresses RTbug #1025.
28    
29            * Doc/thuban.dtd: Add visible parameter to a layer.
30    
31            * Thuban/Model/layer.py (BaseLayer.__init__): Change default value
32            of visible from 1 to True.
33            (Layer.__init__): Change default value of visible from 1 to True.
34    
35            * Thuban/Model/load.py (SessionLoader.start_layer): Read visible
36            parameter.
37    
38            * Thuban/Model/save.py (SessionSaver.write_layer): Save visible
39            parameter.
40    
41            * test/test_load.py: Add new test data contents_test_visible.
42            (LoadSessionTest.setUp): save test data.
43            (LoadSessionTest.testLayerVisibility): Test if the visible flag
44            is loaded correctly.
45    
46            * test/test_save.py (SaveSessionTest.testSingleLayer): Add test
47            for saving an invisible layer.
48    
49    2003-04-29  Jonathan Coles   <[email protected]>
50    
51            * Thuban/UI/mainwindow.py (MainWindow.SetMap): Look up the
52            legend dialog box and tell it to change its map to the one
53            supplied to SetMap(). Fixes RTbug #1770.
54    
55    2003-04-29  Bernhard Herzog  <[email protected]>
56    
57            Next step of table implementation. Introduce a transient database
58            using SQLite that some of the data is copied to on demand. This
59            allows us to do joins and other operations that require an index
60            for good performance with reasonable efficiency. Thuban now needs
61            SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I
62            haven't tested that.
63            
64            * Thuban/Model/transientdb.py: New. Transient database
65            implementation.
66    
67            * test/test_transientdb.py: New. Tests for the transient DB
68            classes.
69    
70            * Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New
71            classes to help automatically remove temporary files and
72            directories.
73            (Session.__init__): New instance variables temp_dir for the
74            temporary directory and transient_db for the SQLite database
75            (Session.temp_directory): New. Create a temporary directory if not
76            yet done and return its name. Use AutoRemoveDir to have it
77            automatically deleted
78            (Session.TransientDB): Instantiate the transient database if not
79            done yet and return it.
80    
81            * Thuban/Model/data.py (ShapefileStore.__init__): Use an
82            AutoTransientTable so that data is copied to the transient DB on
83            demand.
84            (SimpleStore): New class that simply combines a table and a
85            shapefile
86    
87            * Thuban/Model/table.py (Table, DBFTable): Rename Table into
88            DBFTable and update its doc-string to reflect the fact that this
89            is only the table interface to a DBF file. Table is now an alias
90            for DBFTable for temporary backwards compatibility.
91    
92            * Thuban/UI/application.py (ThubanApplication.OnExit): Make sure
93            the last reference to the session goes away so that the temporary
94            files are removed properly.
95    
96            * test/test_load.py (LoadSessionTest.tearDown): Remove the
97            reference to the session to make sure the temporary files are
98            removed.
99    
100    2003-04-29  Bernhard Herzog  <[email protected]>
101    
102            * Thuban/Model/load.py (XMLReader.__init__, XMLReader.read): Turn
103            the __parser instance variable into a normal local variable in
104            read. It's only used there and read will never be called more than
105            once. Plus it introduces a reference cycle that keeps can keep the
106            session object alive for a long time.
107    
108    2003-04-29  Jonathan Coles   <[email protected]>
109    
110            * Thuban/Model/proj.py (Projection): Removed Set*() methods to make
111            Projection an immutable item. Fixes RTbug #1825.
112            (Projection.__init__): Initialize instance variables here.
113            (ProjFile.Replace): New. Replace the given projection object with
114            the new projection object. This solves the problem of needing the
115            mutator Projection.SetProjection() in the ProjFrame class and
116            allows a projection to change parameters without changing its
117            location in the file.
118    
119            * Thuban/UI/mainwindow.py (MainWindow.SaveSessionAs): Dialog should
120            be of type wxSAVE and should verify overwriting a file.
121    
122            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Use the new
123            ProjFile.Replace() method instead of the mutator
124            Projection.SetProjection(). Also requires that we reassign the
125            client data to the new projection.
126    
127            * test/test_proj.py (TestProjection.test): Test GetName() and
128            GetAllParameters()
129            (TestProjFile.test): Remove tests for Set*() methods. Add tests
130            for Replace().
131    
132    2003-04-25  Jonathan Coles   <[email protected]>
133    
134            * Thuban/Model/save.py (SessionSaver.write_projection): Make sure
135            to save the name of the projection.
136    
137            * test/test_save.py (SaveSessionTest.testLayerProjection): New
138            test to verify layer projections are saved correctly.
139    
140    2003-04-25  Jonathan Coles   <[email protected]>
141    
142            * Thuban/Model/proj.py (Projection.SetName): Set the name
143            to "Unknown" if name is None.
144            (Projection.SetAllParameters): New. Set the projection's
145            parameter list to the one supplied.
146            (Projection.SetProjection): New. Set the projection's
147            properties to those of the supplied Projection.
148    
149            * Thuban/UI/mainwindow.py (MainWindow.MapProjection): Set
150            the dialog title to include the map's title.
151            (MainWindow.LayerProjection): Set the dialog title to include
152            the layer's title.
153    
154            * Thuban/UI/projdialog.py (ProjFrame.__ShowError): Consolidate
155            error dialogs into a single method call.
156            (ProjFrame.__VerifyButtons): Add more states to check.
157            (ProjFrame.__GetProjection): Return the current state of an
158            edited projection or None.
159            (ProjFrame.__FillAvailList): Remove checks for states that
160            shouldn't exist.
161            (ProjFrame._OnNew): Clear all selected items and supply
162            a projection panel if necessary.
163    
164            * test/test_proj.py (TestProjFile.test): Add tests for
165            ProjFile.SetAllParameters, ProjFile.SetProjection,
166            ProjFile.SetName.
167    
168    2003-04-25  Jonathan Coles   <[email protected]>
169    
170            * Thuban/UI/projdialog.py (ProjFrame.__FillAvailList): Now
171            takes an optional argument to select the current projection.
172            This does not guarantee that the item is visible due to
173            limited wxWindows functionality. Fixes RTBug #1821.
174    
175    2003-04-25  Jonathan Coles   <[email protected]>
176    
177            * Thuban/Model/load.py (SessionLoader.start_projection): Remember
178            the projection name and use it when constructing the Projection
179            object.
180    
181            * Thuban/Model/proj.py (Projection.__init__): Change the default
182            value for 'name' to None and then test if name is equal to None
183            in the body of the constructor. This way the caller doesn't have to
184            know what the default value should be. Namely, useful in load.py
185            where we have to pick a default value if the 'name' parameter
186            doesn't exist in the XML file.
187    
188            * test/test_load.py (LoadSessionTest.testLayerProjection): New.
189            Tests a file where a layer has a projection.
190    
191    2003-04-25  Jonathan Coles   <[email protected]>
192    
193            * Thuban/Model/layer.py (Layer.TreeInfo): Add an item to the
194            tree for projection information.
195    
196            * Thuban/Model/load.py (XMLReader.GetFilename): Renamed from
197            XMLReader.GetFileName.
198            (SessionLoader): Added support for loading projection tags that
199            appear inside a layer.
200    
201            * Thuban/Model/proj.py (ProjFile): Document the class. Move
202            back to using a list because the order of the projections in
203            the file is important to maintain. Fixes RTbug #1817.
204    
205            * Thuban/Model/resource.py: Rename calls to ProjFile.GetFileName
206            to ProjFile.GetFilename.
207    
208            * Thuban/Model/save.py (SessionSaver.write_layer): Save projection
209            information.
210    
211            * Thuban/UI/projdialog.py (ProjFrame._OnAddToList): Renamed from
212            ProjFrame._OnSaveAs. Removed old dead code from previous
213            implementation.
214            (ProjFrame._OnExport): Add support for exporting more than one
215            projection to a single file.
216            (ProjFrame.__FillAvailList): use string formatting (% operator)
217            to build strings that are (partly) translated. Fixes RTbug #1818.
218    
219            * test/test_proj.py (TestProjFile.test): New. Tests the base ProjFile
220            class.
221    
222    2003-04-24  Bernhard Herzog  <[email protected]>
223    
224            * po/es.po: Updated Spanish translation by Daniel Calvelo Aros
225    
226            * po/fr.po: New. French translation by Daniel Calvelo Aros
227    
228            * Thuban/UI/projdialog.py (ProjFrame._OnSaveAs): Don't translate
229            empty strings.
230    
231    2003-04-24  Jonathan Coles   <[email protected]>
232    
233            * Thuban/Model/layer.py (Layer.GetProjection): New. Needed to
234            implement the interface that the ProjFrame dialog expects.
235    
236            * Thuban/Model/proj.py (Projection.SetName): New. Allows the
237            name of the projection to be changed.
238            (ProjFile): Use a dictionary instead of a list so that removing
239            projections is easier and we are sure about uniqueness.
240            (ProjFile.Remove): Remove the given projection object.
241    
242            * Thuban/Model/resource.py (GetSystemProjFiles, GetUserProjFiles):
243            Return a list with only one projection file instead of searching for
244            any projection file. This simplifies many things if the user can
245            only have one system file and one user file.
246    
247            * Thuban/UI/classgen.py: Change all references to
248            genCombo to genChoice.
249    
250            * Thuban/UI/mainwindow.py: Add a Projection option under the
251            layer menu.
252            (MainWindow.LayerProjection): New. Open up a projection window
253            for a layer.
254    
255            * Thuban/UI/projdialog.py: Large changes to how the dialog is
256            laid out. Use three panels instead of one. One for the list of
257            projections, one for the edit controls, and one for the buttons.
258            Fixed resizing problems so that the dialog resizes correctly
259            when the projection panel changes. Added import/export, save, and
260            new buttons/functionality.
261    
262    2003-04-24  Bernhard Herzog  <[email protected]>
263    
264            First step towards table management. Introduce a simple data
265            abstraction so that we replace the data a layer uses more easily
266            in the next step.
267    
268            * Thuban/Model/data.py: New file with a simple data abstraction
269            that bundles shapefile and dbffile into one object.
270    
271            * Thuban/Model/session.py (Session.OpenShapefile): New method to
272            open shapefiles and return a shape store object
273    
274            * Thuban/Model/layer.py (Layer.__init__): Pass the data as a store
275            object instead of a shapefile filename. This introduces a new
276            instance variable store holding the datastore. For intermediate
277            backwards compatibility keep the old instance variables.
278            (open_shapefile): Removed. No longer needed with the shape store.
279            (Layer.SetShapeStore, Layer.ShapeStore): New methods to set and
280            get the shape store used by a layer.
281            (Layer.Destroy): No need to explicitly destroy the shapefile or
282            table anymore.
283    
284            * Thuban/UI/mainwindow.py (MainWindow.AddLayer)
285            (MainWindow.AddLayer): Use the session's OpenShapefile method to
286            open shapefiles
287    
288            * Thuban/Model/load.py (ProcessSession.start_layer): Use the
289            session's OpenShapefile method to open shapefiles
290    
291            * test/test_classification.py
292            (TestClassification.test_classification): Use the session's
293            OpenShapefile method to open shapefiles and build the filename in
294            a more platform independed way
295    
296            * test/test_layer.py (TestLayer.setUp, TestLayer.tearDown):

302            it to open shapefiles.
303            (TestLayerLegend.tearDown): Make sure that all references to
304            layers and session are removed otherwise we may get a resource
305            leak
306    
307            * test/test_map.py (TestMapAddLayer.test_add_layer)
308            (TestMapWithContents.setUp): Instantiate a session so that we can
309            use it to open shapefiles.
310            (TestMapWithContents.tearDown): Make sure that all references to
311            layers, maps and sessions are removed otherwise we may get a
312            resource leak
313            ("__main__"): use support.run_tests() so that more info about
314            uncollected garbage is printed
315    
316            * test/test_save.py (SaveSessionTest.testSingleLayer): Use the
317            session's OpenShapefile method to open shapefiles
318            ("__main__"): use support.run_tests() so that more info about
319            uncollected garbage is printed
320    
321            * test/test_selection.py (TestSelection.tearDown): Make sure that
322            all references to the session and the selection are removed
323            otherwise we may get a resource leak
324            (TestSelection.get_layer): Instantiate a session so that we can
325            use it to open shapefiles.
326            ("__main__"): use support.run_tests() so that more info about
327            uncollected garbage is printed
328    
329            * test/test_session.py (TestSessionBase.tearDown)
330            (TestSessionWithContent.tearDown): Make sure that all references
331            to the session and layers are removed otherwise we may get a

333            (TestSessionWithContent.setUp): Use the session's OpenShapefile
334            method to open shapefiles
335    
336    2003-04-24  Jonathan Coles   <[email protected]>
337    
338            * Thuban/Model/load.py (XMLReader.read): Should have been checking
339            if the file_or_filename object had the 'read' attribute.
340    
341    2003-04-23  Jonathan Coles   <[email protected]>
342    
343            * Thuban/Model/resource.py: Fixes RTbug #1813.

345            Always pass the exceptions up to the caller.
346            (GetProjFiles): If the directory can't be read return an empty list.
347            If any of the proj files can't be read skip that file and go
348            on to the next one.
349    
350            * test/test_proj.py: Added test cases to handle nonexistent files,
351            unreadable files, and files that don't parse correctly.
352    
353    2003-04-23  Jonathan Coles   <[email protected]>
354

364    
365    2003-04-23  Jonathan Coles   <[email protected]>
366    
367            * Thuban/Model/load.py (XMLReader): Renamed from XMLProcessor to
368            promote symmetry. There now exists XMLReader and XMLWriter.
369            (XMLReader.read): New. Call to read the given file descriptor or
370            filename.
371            (XMLReader.close): New. Make sure the file is closed.
372            (XMLReader.GetFileName): New. Return just the file name that is being
373            read from.
374            (XMLReader.GetDirectory): New. Return just the directory of the file
375            that is being read.
376            (XMLReader.AddDispatchers): New. Take a dictionary which contains
377            the names of functions to call as the XML tree is parsed.
378            (XMLReader.startElementNS): Updated to use new dispatcher dictionary.
379            (XMLReader.endElementNS): Updated to use new dispatcher dictionary.
380            (SessionLoader): Removed class variables start_dispatcher and
381            end_dispatcher since this functionality is now part of a class
382            instance. Fixes RTbug #1808.
383            (SessionLoader.__init__): Add dispatcher functions.
384            (load_xmlfile): Code was moved into the XMLReader.read().
385            (load_session): Use modified SessionLoader.
386    
387            * Thuban/Model/map.py (Map.GetProjection): New. Returns the
388            map's projection.
389    
390            * Thuban/Model/proj.py (Projection.GetParameters): Renamed to
391            GetAllParameters.
392            (Projection.GetParameter): Returns the value for the given parameter.
393    
394            * Thuban/Model/resource.py: Use XMLReader and XMLWriter.

405    
406            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Use a wxChoice
407            control instead of a wxComboBox. wxChoice controls do not generate
408            events as the uses highlights possible choices which fixes problems
409            with resizing the dialog when the use selects an option.
410    
411            * Thuban/UI/classifier.py (Classifier.__init__): Use a wxChoice

434            (Layer.ShapeType, Layer.Shape): No need to call
435            self.open_shapefile since it's always called in __init__
436    
437            * Thuban/UI/application.py (ThubanApplication.MainLoop): Removed.
438            In wxPython 2.4 there's no need to extend MainLoop anymore since

440    
441    2003-04-16  Jonathan Coles   <[email protected]>
442    
443            Initial putback of projection management code. Includes new
444            classes to read and write projection files. The current load

468    
469            * Thuban/Model/classification.py: Use repr() around values
470            in the ClassGroup*.__repr__() methods so it is clearer when
471            a value is a string and when it is a number.
472    
473            * test/test_load.py: Rework the classification test to test
474            that we can load old files.
475            (testLabels): Test a file where the groups have labels.
476    
477    2003-04-16  Bernhard Herzog  <[email protected]>

487            handling of these low-level parameters so that each s_draw_info
488            instance is handled as a CObject at python level that also
489            contains real references to the actual python objects which
490            contain the values in the struct. Add free_draw_info as the
491            destructor.
492            (draw_polygon_shape): Add the py_draw_info parameter which must a

777    2003-04-07  Jonathan Coles   <[email protected]>
778    
779            Since we now say that the order of the groups in a classification
780            matters, it makes sense to be able to manipulate that order. Most
781            of the changes to Thuban/Model/classification.py are to that end.
782    
783            * Thuban/Model/classification.py (Classification.AppendGroup,
784            Classification.InsertGroup, Classification.ReplaceGroup,
785            Classification.RemoveGroup, Classification.GetGroup): Do as the
786            names imply.
787            (Classification.FindGroup): This was called GetGroup, but GetGroup
788            takes an index, while FindGroup takes a value.
789            (Classification.__deepcopy__): Copy all the groups, BUT NOT THE LAYER
790            REFERENCE. Currently there is a cyclic reference between the layer
791            and its classification. If the classification doesn't need to know
792            its owning layer we can change this, since it may make sense to be
793            able to use the same classification with different layers.
794    
795            * Thuban/Model/load.py: Use Classification.AppendGroup(), not AddGroup()
796    
797            * Thuban/UI/classgen.py: Use Classification.AppendGroup(),
798            not AddGroup()
799    
800            * Thuban/UI/classifier.py: Now that we can depend on the order in
801            a Classification and have methods to manipulate that order we don't
802            need to use our own data structures in the grid. We can simply make
803            the grid/table access the information they need from a copy of
804            the classification object.
805            (Classifier._OnCloseBtn): Event handler for when the user clicks
806            'Close'. This is needed so if the user applies changes and then
807            continues to change the table the user has the option of discarding
808            the most recent changes and keeping what they applied.
809    
810            * Thuban/UI/mainwindow.py: Put "Show Legend" and "Show Session Tree"
811            into the same group.
812    
813            * extensions/thuban/wxproj.cpp (check_version): If Thuban is compiled
814            with a really old version of proj, PJ_VERSION won't even be defined.
815            If it isn't defined then just compile so that the function always
816            returns Py_False.
817    
818            * test/test_classification.py: Fix tests to use the renamed methods.
819            Still need to write tests for the new methods.
820    
821    2003-04-04  Jonathan Coles   <[email protected]>
822    
823            * Thuban/UI/classifier.py (Classifier.__SelectField): Move the
824            call to SetSelection out of the method and before the call
825            to __SelectField in __init__. This prevents a recursion of events
826            when _OnFieldSelect is triggered by the user.
827    
828    2003-04-04  Jonathan Coles   <[email protected]>
829    
830            * Thuban/Model/classification.py: Rename Color.None to
831            Color.Transparent.
832            (ClassGroupProperties.SetLineColori, ClassGroupProperties.SetFill):
833            Don't bother copying the color, since Colors are immutable.
834    
835            * Thuban/Model/color.py, Thuban/Model/layer.py, Thuban/Model/load.py,
836            Thuban/UI/classifier.py, Thuban/UI/mainwindow.py,
837            Thuban/UI/renderer.py, Thuban/UI/view.py:
838            Rename Color.None to Color.Transparent.
839        
840            * test/test_classification.py, test/test_load.py: Rename Color.None
841            to Color.Transparent.
842    
843    2003-04-04  Jonathan Coles   <[email protected]>
844    
845            * Thuban/Model/classification.py: Fix assert calls.
846            (ClassGroupProperties.SetLineColor, ClassGroupProperties.SetFill):
847            Copy the color parameter rather than hold onto a reference.
848    
849            * Thuban/Model/color.py (Color.__copy__, Color.__deepcopy): Copy
850            the color object.
851            (NoColor.__copy__, NoColor.__deepcopy): Return 'self' so that we
852            are sure there exists only one refernce to Color.None in the system.
853            This allows us to use 'is' rather than the comparision functions.
854            
855            * Thuban/Model/save.py: Fix assert calls.
856            
857            * Thuban/UI/classifier.py: Fix assert calls.
858            (ClassGrid._OnCellDClick): Call up to the classifier to open the
859            dialog to edit the groups properties.
860            (ClassGrid._OnCellResize): Make sure that the scollbars are drawn
861            correctly if a cell is resized.
862            (ClassTable.SetClassification): New. Changes the classification
863            that is in the table.
864            (ClassTable.__SetRow): Allow groups to be prepended.
865            (Classifier): New code for opening the EditProperties and
866            GenerateRanges dialogs.
867            (SelectPropertiesDialog.__GetColor): Only set the color in the
868            color dialog if the current color is not None.
869

871            
872            * Thuban/UI/legend.py: Fix assert calls.
873            
874            * Thuban/UI/renderer.py: Fix assert calls.
875            
876            * Thuban/UI/classgen.py (ClassGenDialog): Dialog for generating
877            classifications.
878            (GenRangePanel): Panel specific to range generation.
879            (GenSingletonPanel): Panel specific to singleton generation.
880            (ClassGenerator): Class responsible for actually generating
881            the classification from the data gathered in the dialog box.
882            (PropertyRamp): Generates properties whose values range from
883            a starting property to an ending property.
884    
885    2003-04-03  Bernhard Herzog  <[email protected]>
886    
887            * test/support.py (print_garbage_information): New function that
888            prints information about still connected messages and memory
889            leaks.
890            (run_suite): Removed.
891            (run_tests): New function for use as a replacement of
892            unittest.main in the test_* files. This one calls
893            print_garbage_information at the end.
894    
895            * test/runtests.py (main): Use support.print_garbage_information
896    
897            * test/test_layer.py: Use support.run_tests instead of
898            unittest.main so we get memory leak information
899            (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
900            (TestLayer.test_point_layer, TestLayer.test_empty_layer)
901            (TestLayerLegend.test_visibility): Call the layer's Destroy method
902            to fix a memory leak.
903    
904            * test/test_classification.py: Use support.run_tests instead of
905            unittest.main so we get memory leak information
906            (TestClassification.test_classification): Call the layer's Destroy
907            method to fix a memory leak.
908    
909    2003-04-02  Bernhard Herzog  <[email protected]>
910    
911            * extensions/thuban/wxproj.cpp (check_version, check_version_gtk):

913            PyArg_ParseTuple correctly.
914    
915            * Thuban/UI/application.py (ThubanApplication.OpenSession): Make
916            sure the filename is absolute to avoid problems when saving the
917            session again
918    
919            * Thuban/Model/table.py: Remove unnecessary import. Fix a typo.
920    
921    2003-04-01  Jonathan Coles   <[email protected]>
922    
923            *  Thuban/UI/renderer.py (MapRenderer.draw_point_shape): Check
924            that there actually are points in the returned list of points
925            before trying to index into the list. The list may be empty if
926            the shape is a Null Shape.
927    
928    2003-04-01  Bernhard Herzog  <[email protected]>
929    
930            * test/test_map.py: Don't use from <module> import *
931    
932    2003-04-01  Jonathan Coles   <[email protected]>
933

949            * Thuban/UI/dock.py (DockableWindow.UnDock): Restore size and
950            position (although position doesn't work yet under GTK).
951            (DockableWindow.Destroy): New. Called when the window must be
952            closed. Namely needed when the DockFrame closes and must close
953            its children.
954            (DockFrame): Listen for EVT_CLOSE and destroy all children.
955    
956            * Thuban/UI/legend.py (LegendPanel.Destroy): New. Cleans up
957            when then window is told to close.
958            (LegendTree._OnMsgLayerChanged): Fixes a seg fault bug. See
959            comment in source for more info.
960    
961            * Thuban/UI/main.py: Show the legend by default when Thuban starts.
962    
963            * Thuban/UI/mainwindow.py: Renamed OnClose to _OnClose for
964            symmetry with other such methods.
965            (MainWindow.ShowLegend): Show the legend docked by default.
966    
967    2003-03-28  Jonathan Coles   <[email protected]>
968    
969            * Thuban/UI/classifier.py: Support for highlighting a specific
970            group within the grid when the classification dialog is opened.
971            Also contains a lot of debugging printouts which will later
972            be removed.
973    
974            * Thuban/UI/dock.py: Complete rework on the dock code so that
975            that it is fairly removed from the rest of the Thuban application.
976            It is easy to add new docks which the rest of the program having
977            to be aware of them.
978    
979            * Thuban/UI/legend.py: Modifications to support selecting a

981            are drawn when the layer is visible/invisible.
982

990    
991            * Thuban/UI/legend.py: Removed unnecessary LegendDialog class.
992            (LegendPanel): Removed _OnDock()/_OnUnDock() methods which are
993            now part of DockableWindow.

995            map.
996            (LegendTree._OnSelChanged): Call LegendPanel.DoOnSelChanged()
997            with the selected layer and/or group.
998    
999    2003-03-26  Jonathan Coles   <[email protected]>
1000    
1001            This putback contains the code for dockable windows. There is
1002            no support in wxWindows as of this date for windows that can
1003            attach themselves to other windows.
1004    
1005            The current model contains a DockableWindow which has a parent
1006            window for when it is detached and a dock window that it puts
1007            its contents in when it is docked. The contents of a DockableWindow
1008            must be a DockPanel. DockPanel itself derives from wxPanel.
1009    
1010            * Thuban/Model/layer.py (Layer.ClassChanged): Send a LAYER_CHANGED
1011            message, not a LAYER_LEGEND_CHANGED message.
1012    
1013            * Thuban/Model/map.py (Map): Forward LAYER_CHANGED messages.
1014    
1015            * Thuban/UI/classifier.py (Classifier.__init__): Use wxADJUST_MINSIZE
1016            as one of the style properties for the fieldTypeText item to
1017            be sure that its size is correct when the text changes.
1018    
1019            * Thuban/UI/dock.py: New. Classes for the DockPanel and
1020            DockableWindow.
1021    
1022            * Thuban/UI/legend.py: Added some more buttons and made the
1023            LegendPanel a DockPanel.
1024    
1025            * Thuban/UI/mainwindow.py: Added sash windows to the main window
1026            and supporting functions for manipulating the sashes.
1027            (MainWindow.ShowLegend): Create a DockableWindow with the
1028            LegendPanel as the contents.
1029    
1030            * Thuban/UI/messages.py: Added DOCKABLE_* messages
1031    
1032            * Thuban/UI/view.py (MapCanves.SetMap): Listen for LAYER_CHANGED,
1033            not LAYER_LEGEND_CHANGED, messages.
1034    
1035    2003-03-25  Jonathan Coles   <[email protected]>
1036    
1037            * setup.py: Added custom script bdist_rpm_build_script so that
1038            when the rpm is built the path to wx-config is correct.
1039    
1040            * setup.cfg: Added line saying to use the custom build script
1041    
1042    2003-03-20  Jonathan Coles   <[email protected]>
1043    
1044            Initial implementation of the Legend.
1045    
1046            * Thuban/UI/legend.py: New. Creates a window that shows the map's
1047            Legend information and allows the user to add/modify classifications
1048            and how the layers are drawn on the map.
1049    
1050            * setup.py: New command 'build_docs' which currently uses
1051            happydoc to generate html documentation for Thuban.
1052    
1053            * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
1054            Returns a string which is appropriately describes the group.
1055    
1056            * Thuban/Model/layer.py (Layer.SetClassification): Generate a
1057            LAYER_CHANGED event instead of a LAYER_LEGEND_CHANGED event.
1058    
1059            * Thuban/Model/map.py (Map): Rename messages and use new, more
1060            specific, messages.
1061    
1062            * Thuban/Model/messages.py: New message to indicate that a layer's
1063            data has changed (LAYER_CHANGED). New map messages to indicate
1064            when layers have been added/removed/changed or if the stacking order
1065            of the layers has changed.
1066    
1067            * Thuban/Model/session.py: Rename and use new messages.
1068    
1069            * Thuban/UI/classifier.py: Remember if any changes have actually
1070            been applied so that if the dialog is cancelled without an application
1071            of changes we don't have to set a new classification.
1072            (ClassDataPreviewer): Pulled out the window specific code and put it
1073            ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
1074            symbols on any DC.
1075            
1076            * Thuban/UI/mainwindow.py: New code to open the legend.
1077    
1078            * Thuban/UI/view.py: Use new message names.
1079    
1080    2003-03-19  Jonathan Coles   <[email protected]>
1081    
1082            * Thuban/UI/main.py (verify_versions): New. Checks the versions
1083            of Python, wxPython, and some other libraries.
1084    
1085            * extensions/thuban/wxproj.cpp (check_version): Checks the given
1086            version against what wxproj was compiled with.
1087            (check_version_gtk): If wxproj was compiled with gtk then check
1088            the given version against the version of the gtk library
1089            currently being used.
1090    
1091    2003-03-14  Bernhard Herzog  <[email protected]>
1092    
1093            * test/test_command.py: Run the tests when the module is run as a
1094            script
1095    
1096    2003-03-14  Bernhard Herzog  <[email protected]>
1097    
1098            Implement selection of multiple selected shapes in the same layer:
1099    
1100            - Introduce a new class to hold the selection. This basically
1101              replaces the interactor which was nothing more than the
1102              selection anyway. A major difference is of course that the new
1103              selection class supports multiple selected shapes in one layer
1104            
1105            - Move the object that represents the selection from the
1106              application to the canvas. The canvas is a better place than the
1107              application because the selection represents which shapes and
1108              layer of the map displayed by the canvas are selected and
1109              affects how the map is drawn.
1110    
1111            - Make the selection and its messages publicly available through
1112              the mainwindow.
1113    
1114            - The non-modal dialogs do not get a reference to the interactor
1115              anymore as they can simply refer to their parent, the
1116              mainwindow, for the what the interactor had to offer.
1117    
1118            * Thuban/UI/selection.py: New module with a class to represent the
1119            selection.
1120    
1121            * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
1122            these unused messages
1123    
1124            * Thuban/UI/application.py (ThubanApplication.OnInit)
1125            (ThubanApplication.OnExit, ThubanApplication.SetSession): The
1126            interactor is gone now.
1127            (ThubanApplication.CreateMainWindow): There is no interactor
1128            anymore so we pass None as the interactor argument for now for
1129            compatibility.
1130    
1131            * Thuban/UI/view.py (MapCanvas.delegated_messages)
1132            (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
1133            Unsubscribe, delegate messages according to the delegated_messages
1134            class variable.
1135            (MapCanvas.__getattr__, MapCanvas.delegated_methods): Get some
1136            attributes from instance variables as described with the
1137            delegated_methods class variable.
1138            (MapCanvas.__init__): New instance variable selection holding the
1139            current selection
1140            (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
1141            pass them on to the renderer
1142            (MapCanvas.SetMap): Clear the selection when a different map is
1143            selected.
1144            (MapCanvas.shape_selected): Simple force a complete redraw. The
1145            selection class now takes care of only issueing SHAPES_SELECTED
1146            messages when the set of selected shapes actually does change.
1147            (MapCanvas.SelectShapeAt): The selection is now managed in
1148            self.selection
1149    
1150            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
1151            (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
1152            Unsubscribe, delegate messages according to the delegated_messages
1153            class variable.
1154            (MainWindow.delegated_methods, MainWindow.__getattr__): Get some
1155            attributes from instance variables as described with the
1156            delegated_methods class variable.
1157            (MainWindow.__init__): The interactor as ivar is gone. The
1158            parameter is still there for compatibility. The selection messages
1159            now come from the canvas.
1160            (MainWindow.current_layer, MainWindow.has_selected_layer):
1161            Delegate to the the canvas.
1162            (MainWindow.LayerShowTable, MainWindow.Classify)
1163            (MainWindow.identify_view_on_demand): The dialogs don't need the
1164            interactor parameter anymore.
1165    
1166            * Thuban/UI/tableview.py (TableFrame.__init__)
1167            (LayerTableFrame.__init__, LayerTableFrame.OnClose)
1168            (LayerTableFrame.row_selected): The interactor is gone. It's job
1169            from the dialog's point of view is now done by the mainwindow,
1170            i.e. the parent. Subscribe to SHAPES_SELECTED instead
1171            of SELECTED_SHAPE
1172            
1173            * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
1174            is gone. It's job from the dialog's point of view is now done by
1175            the mainwindow, i.e. the parent.
1176            
1177            * Thuban/UI/classifier.py (Classifier.__init__): The interactor is

1184            (SessionTreeCtrl.__init__): New parameter mainwindow which is
1185            stored as self.mainwindow. The mainwindow is need so that the tree
1186            can still subscribe to the selection messages.
1187            (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
1188            (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
1189            selection is now accessible through the mainwindow. Subscribe to
1190            SHAPES_SELECTED instead of SELECTED_SHAPE
1191    
1192            * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
1193            SHAPES_SELECTED message now.
1194            (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
1195            so deal with multiple shapes
1196            (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
1197            gone. It's job from the dialog's point of view is now done by the
1198            mainwindow, i.e. the parent.
1199    
1200            * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
1201            parameter is now a list of shape ids.
1202            (RecordTable.SetTable): The second parameter is now a list of
1203            indices.
1204    
1205            * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the

1207            list of shape ids.
1208            (MapRenderer.draw_label_layer): Deal with multiple selected
1209            shapes. Rearrange the code a bit so that the setup and shape type
1210            distinctions are only executed once.
1211

1215    
1216            * Thuban/Model/load.py: Temporary fix so that the xml reader
1217            doesn't cause Thuban to crash.
1218    
1219            * Thuban/Model/layer.py: Handle the cyclic references between
1220            a layer and its classification better, and be sure to disconnect
1221            the classification from the layer when the layer is destroyed
1222            so that we don't maintain a cyclic reference that may not be
1223            garbage collected.
1224    
1225            * Thuban/Model/classification.py: See comment for layer.py.
