25            message if the assertion fails and don't return the return value
26            of self.assert_. In assertFloatSeqEqual the return meant that not

87            with the mouse position into the status bar into the new method

89    
90    2002-09-12  Bernhard Herzog  <[email protected]>
91    
92            * Thuban/UI/mainwindow.py (MainWindow.RunMessageBox): Center the

120    2002-09-02  Bernhard Herzog  <[email protected]>
121    
122            * Thuban/UI/view.py: Get rid of the idle redraw. This is done by
123            wxWindows already and our implementation doesn't work correctly
124            with wxGTK 2.3:
125            (MapCanvas.__init__): Remove the instance variable
126            (MapCanvas.OnPaint): Always call do_redraw when there's a map to
127            be drawin
128            (MapCanvas.OnIdle): Removed.
129    
130            * Thuban/UI/view.py (MapCanvas.unprojected_rect_around_point): Add
131            a parameter to determine the size of the rectangle.
132            (MapCanvas.find_shape_at): Create the box around the point on a
133            layer by layer basis and make the size depend on the shape type.
134            This solves a problem with the selection of point shapes at the
135            border of the layer's bounding box
136    
137    2002-08-30  Bernhard Herzog  <[email protected]>
138    
139            * Thuban/UI/mainwindow.py (MainWindow.CanRemoveLayer): New method
140            for the sensitivity  of remove layer.

142            (Command layer_remove): Use _can_remove_layer
143

145            determine whether a given layer can be deleted.
146    
147            * Thuban/UI/view.py (MapCanvas.__init__, MapCanvas.OnPaint)
148            (MapCanvas.do_redraw): Get rid of the unused update_region
149            instance variable
150    
151            * Thuban/UI/view.py: Add/update some doc-strings.
152    
153            * test/: new subdirectory with a bunch of unit tests.
154    
155            * test/README, test/test_table.py, test/test_save.py,
156            test/test_menu.py, test/test_load.py: Initial set of tests and
157            brief instructions on how to run them
158    
159    2002-08-29  Bernhard Herzog  <[email protected]>
160    
161            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Handle
162            arcs with multiple parts.
163    
164            * Thuban/UI/view.py (ZoomInTool.MouseUp, ZoomOutTool.MouseUp):
165            Handle degenrate rectangles.
166    
167            * Thuban/Model/table.py: Make writing records work correctly:
168            (Table.__init__): Keep track of whether the DBF is open for
169            writing
170            (Table.write_record): Open the DBF file for writing when necessary
171    
172    2002-08-27  Bernhard Herzog  <[email protected]>
173    
174            * Thuban/Model/table.py (Table.write_record, Table.__init__): Open
175            dbf files only for reading by default. Use a new writable dbf
176            object for writing.
177    
178    2002-08-26  Bernhard Herzog  <[email protected]>
179    
180            * Thuban/UI/mainwindow.py: Refactor the context creation:
181            (MainWindow.Context): New method to return a context
182            (MainWindow.invoke_command, MainWindow.update_command_ui): Use the
183            new method
184    
185            * Thuban/UI/tableview.py (TableGrid, LayerTableGrid): Split the
186            layer table specific code from TableGrid into LayerTableGrid
187            (TableFrame, LayerTableFrame): Split the layer table specific code
188            from TableFrame into LayerTableFrame
189            (LayerTableGrid.select_shape): Remove a debug print
190    
191            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Use the
192            LayerTableFrame
193    
194    2002-08-23  Bernhard Herzog  <[email protected]>
195    
196            * Thuban/Model/layer.py (Layer.__init__): Make sure we have an
197            absolute filename.
198    
199    2002-08-22  Bernhard Herzog  <[email protected]>
200    
201            * Thuban/Model/table.py (Table.write_record): New method to write
202            records.
203            (Table.__init__): Open the DBF file for writing too.
204    
205            * Thuban/UI/controls.py (RecordTable.SetValue): Write the value
206            into the underlying table.
207    
208            * extensions/shapelib/shapefil.h (DBFCommit),
209            extensions/shapelib/dbfopen.c (DBFCommit): New API function to
210            commit any changes made to the DBF file.

212            * Thuban/UI/mainwindow.py (make_check_current_tool)
213            (_tool_command): Put the code that generates the "checked"
214            callback into a separate function so that we can reuse it
215            elsewhere
216    
217            * Thuban/Model/save.py (Saver): New class to handle serializing a
218            session into an XML file. The main reason to introduce a class is
219            that applications built on Thuban can derive from it so that they
220            can save additional information in a session file.
221            (save_session): Delegate almost all the work to the Saver class.
222            Rename the filename argument to file because it may be a file like
223            object now.
224    
225            * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
226            code. Remove the little test code which would be executed when the
227            module is run as a script which didn't work anymore since it can't
228            import the other Thuban modules.
229            (ProcessSession, load_session): Refactor the ProcessSession to
230            have one method for each element start and end tag so that derived
231            classes can easily override the processing of individual tags.
232            Also, always parse with namespaces enabled because applications
233            built on top of Thuban will likely use namespaces if they extend
234            the session file format.
235    
236    2002-08-21  Bernhard Herzog  <[email protected]>
237    
238            * setup.py (ThubanInstall.run): Don't repr install_lib_orig
239            because thubaninit_contents will do it for us.
240    
241    2002-08-16      Jan-Oliver Wagner <[email protected]>
242    
243            * Thuban/UI/mainwindow.py: menu item 'show session tree' now disable if
244            tree window already open
245    
246    2002-08-15  Bernhard Herzog  <[email protected]>
247    
248            * Thuban/Model/layer.py (Layer.Destroy): Call the unboundd method

252            when we have actually captured it.
253    
254            * Thuban/Model/layer.py (Layer.Destroy): New. Explicitly close the
255            shapefile and destroy the table.
256    
257            * Thuban/Model/table.py (Table.Destroy): New. Close the DBF file.
258    
259    2002-08-14  Bernhard Herzog  <[email protected]>
260    
261            * Thuban/UI/controls.py (RecordTable.__init__): Remove the unused
262            instance variable columns
263            (RecordTable.GetTypeName): row and col may be negative in some
264            cases.
265    
266            * setup.py (InstallLocal.initialize_options)
267            (InstallLocal.finalize_options, InstallLocal.user_options): New
268            option create-init-file to build a thubaninit.py when running
269            install_local
270            (InstallLocal.run): Create the thubaninit.py module when requested
271            (thubaninit_contents): Split the template into several parts and
272            create a new function thubaninit_contents that creates the
273            contents of a thubaninit module.
274            (ThubanInstall.run): Use the new function to create the thubaninit
275            module.
276

280            cleanup.
281            (ThubanApplication.MainLoop): Extend to automatically call OnExit.
282    
283            * Thuban/Model/session.py (Session.Destroy): Don't bypass the
284            direct base class' Destroy method.
285    
286            * Thuban/Model/map.py (Map.ClearLayers): New method to delete all
287            layers.
288            (Map.Destroy): Destroy the label_layer as well and call the
289            inherited Desatroymethod first so that no more messages are
290            issued.
291            (Map.RaiseLayer, Map.LowerLayer): Only issue LAYERS_CHANGED
292            message if the stacking order actually has changed. Add
