16

58            (MainWindow.set_position_text): Put the code that puts the text
59            with the mouse position into the status bar into the new method
60            set_position_text so that it can overwritten in derived classes.
61    
62    2002-09-12  Bernhard Herzog  <[email protected]>
63    
64            * Thuban/UI/mainwindow.py (MainWindow.RunMessageBox): Center the

77            (_tool_command): Add sensitive parameter

92    2002-09-02  Bernhard Herzog  <[email protected]>
93    
94            * Thuban/UI/view.py: Get rid of the idle redraw. This is done by
95            wxWindows already and our implementation doesn't work correctly
96            with wxGTK 2.3:
97            (MapCanvas.__init__): Remove the instance variable
98            (MapCanvas.OnPaint): Always call do_redraw when there's a map to
99            be drawin
100            (MapCanvas.OnIdle): Removed.
101    
102            * Thuban/UI/view.py (MapCanvas.unprojected_rect_around_point): Add
103            a parameter to determine the size of the rectangle.
104            (MapCanvas.find_shape_at): Create the box around the point on a
105            layer by layer basis and make the size depend on the shape type.
106            This solves a problem with the selection of point shapes at the
107            border of the layer's bounding box
108    
109    2002-08-30  Bernhard Herzog  <[email protected]>
110    
111            * Thuban/UI/mainwindow.py (MainWindow.CanRemoveLayer): New method
112            for the sensitivity  of remove layer.
113            (_can_remove_layer): New. Sensitivity callback for remove layer
114            (Command layer_remove): Use _can_remove_layer
115    
116            * Thuban/Model/map.py (Map.CanRemoveLayer): New method to
117            determine whether a given layer can be deleted.
118    
119            * Thuban/UI/view.py (MapCanvas.__init__, MapCanvas.OnPaint)
120            (MapCanvas.do_redraw): Get rid of the unused update_region
121            instance variable
122    
123            * Thuban/UI/view.py: Add/update some doc-strings.
124    
125            * test/: new subdirectory with a bunch of unit tests.
126    
127            * test/README, test/test_table.py, test/test_save.py,
128            test/test_menu.py, test/test_load.py: Initial set of tests and
129            brief instructions on how to run them
130    
131    2002-08-29  Bernhard Herzog  <[email protected]>
132    
133            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Handle
134            arcs with multiple parts.
135    
136            * Thuban/UI/view.py (ZoomInTool.MouseUp, ZoomOutTool.MouseUp):
137            Handle degenrate rectangles.
138    
139            * Thuban/Model/table.py: Make writing records work correctly:
140            (Table.__init__): Keep track of whether the DBF is open for
141            writing
142            (Table.write_record): Open the DBF file for writing when necessary
143    
144    2002-08-27  Bernhard Herzog  <[email protected]>
145    
146            * Thuban/Model/table.py (Table.write_record, Table.__init__): Open
147            dbf files only for reading by default. Use a new writable dbf
148            object for writing.
149    
150    2002-08-26  Bernhard Herzog  <[email protected]>
151    
152            * Thuban/UI/mainwindow.py: Refactor the context creation:
153            (MainWindow.Context): New method to return a context
154            (MainWindow.invoke_command, MainWindow.update_command_ui): Use the
155            new method
156    
157            * Thuban/UI/tableview.py (TableGrid, LayerTableGrid): Split the
158            layer table specific code from TableGrid into LayerTableGrid
159            (TableFrame, LayerTableFrame): Split the layer table specific code
160            from TableFrame into LayerTableFrame
161            (LayerTableGrid.select_shape): Remove a debug print
162    
163            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Use the
164            LayerTableFrame
165    
166    2002-08-23  Bernhard Herzog  <[email protected]>
167    
168            * Thuban/Model/layer.py (Layer.__init__): Make sure we have an
169            absolute filename.
170    
171    2002-08-22  Bernhard Herzog  <[email protected]>
172    
173            * Thuban/Model/table.py (Table.write_record): New method to write
174            records.
175            (Table.__init__): Open the DBF file for writing too.
176    
177            * Thuban/UI/controls.py (RecordTable.SetValue): Write the value
178            into the underlying table.
179    
180            * extensions/shapelib/shapefil.h (DBFCommit),
181            extensions/shapelib/dbfopen.c (DBFCommit): New API function to
182            commit any changes made to the DBF file.
183    
184            * Thuban/UI/mainwindow.py (make_check_current_tool)
185            (_tool_command): Put the code that generates the "checked"
186            callback into a separate function so that we can reuse it
187            elsewhere
188    
189            * Thuban/Model/save.py (Saver): New class to handle serializing a
190            session into an XML file. The main reason to introduce a class is
191            that applications built on Thuban can derive from it so that they
192            can save additional information in a session file.
193            (save_session): Delegate almost all the work to the Saver class.
194            Rename the filename argument to file because it may be a file like
195            object now.
196    
197            * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
198            code. Remove the little test code which would be executed when the
199            module is run as a script which didn't work anymore since it can't
200            import the other Thuban modules.
201            (ProcessSession, load_session): Refactor the ProcessSession to
202            have one method for each element start and end tag so that derived
203            classes can easily override the processing of individual tags.
204            Also, always parse with namespaces enabled because applications
205            built on top of Thuban will likely use namespaces if they extend
206            the session file format.
207    
208    2002-08-21  Bernhard Herzog  <[email protected]>
209    
210            * setup.py (ThubanInstall.run): Don't repr install_lib_orig
211            because thubaninit_contents will do it for us.
212    
213    2002-08-16      Jan-Oliver Wagner <[email protected]>
214    
215            * Thuban/UI/mainwindow.py: menu item 'show session tree' now disable if
216            tree window already open
217    
218    2002-08-15  Bernhard Herzog  <[email protected]>
219    
220            * Thuban/Model/layer.py (Layer.Destroy): Call the unboundd method
221            with self.
222    
223            * Thuban/UI/view.py (MapCanvas.OnLeftUp): Only release the mouse
224            when we have actually captured it.
225    
226            * Thuban/Model/layer.py (Layer.Destroy): New. Explicitly close the
227            shapefile and destroy the table.
228    
229            * Thuban/Model/table.py (Table.Destroy): New. Close the DBF file.
230    
231    2002-08-14  Bernhard Herzog  <[email protected]>
232    
233            * Thuban/UI/controls.py (RecordTable.__init__): Remove the unused
234            instance variable columns
235            (RecordTable.GetTypeName): row and col may be negative in some
236            cases.
237    
238            * setup.py (InstallLocal.initialize_options)
239            (InstallLocal.finalize_options, InstallLocal.user_options): New
240            option create-init-file to build a thubaninit.py when running
241            install_local
242            (InstallLocal.run): Create the thubaninit.py module when requested
243            (thubaninit_contents): Split the template into several parts and
244            create a new function thubaninit_contents that creates the
245            contents of a thubaninit module.
246            (ThubanInstall.run): Use the new function to create the thubaninit
247            module.
248

257    
258            * Thuban/Model/map.py (Map.ClearLayers): New method to delete all
259            layers.
260            (Map.Destroy): Destroy the label_layer as well and call the
261            inherited Desatroymethod first so that no more messages are
262            issued.
263            (Map.RaiseLayer, Map.LowerLayer): Only issue LAYERS_CHANGED
264            message if the stacking order actually has changed. Add

284            search in.
285            (MapCanvas.SelectShapeAt): New parameter layer to restrict the

324            (ThubanApplication.CreateMainWindow): Put the mainwindow
325            instantiation into a separate method so that it can be overridden
