1    2003-03-12  Jan-Oliver Wagner <[email protected]>
2    
3            * HOWTO-Release: New. Information on the steps for releasing
4            a new version of Thuban.
5    
6    2003-03-11  Jonathan Coles   <[email protected]>
7    
8            * Thuban/UI/classifier.py: Add normal border to SelectPropertiesDialog.
9            Use True instead of true.
10            (Classifier): Should have a single panel in which all the controls lie.
11    
12            * Thuban/UI/proj4dialog.py: Add normal border.
13    
14            * Thuban/UI/tree.py: Fixed problem with bad item images under Windows.
15    
16            * Thuban/UI/mainwindow.py: Use True instead of true.
17    
18            * setup.py: Update some definitions to use wxWindows2.4 files
19    
20            * Data/iceland_sample_class.thuban: Fixed file so that the
21            field_type information is present.
22    
23    2003-03-10  Jonathan Coles   <[email protected]>
24    
25            * Thuban/UI/classifier.py (Classifier.__init__): Make the
26            field type label grow so that when the text changes the
27            size is updated correctly. This may be a wxWindows bug.
28    
29    2003-03-10  Jonathan Coles   <[email protected]>
30    
31            * Thuban/UI/application.py: Changed SESSION_CHANGED to
32            SESSION_REPLACED.
33    
34            * Thuban/UI/classifier.py: Wrap text with _().
35            (ClassGrid.CreateTable): Set dimensions and size hints here,
36            instead of in Reset, so we only set the size once.
37    
38            * Thuban/UI/dialogs.py: Don't need Shutdown(); just use Close()!
39    
40            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
41            Call Close() instead of Shutdown().
42    
43            * Thuban/UI/messages.py: Changed SESSION_CHANGED to SESSION_REPLACED.
44    
45            * Thuban/UI/tree.py: Changed SESSION_CHANGED to SESSION_REPLACED.
46            Go back to using OnClose() instead of Shutdown().
47    
48    2003-03-10  Jonathan Coles   <[email protected]>
49    
50            * Thuban/UI/classifier.py (Classifier): SelectField() needed
51            to know the old field index as well as the new one.
52    
53    2003-03-10  Jonathan Coles   <[email protected]>
54    
55            * Thuban/UI/classifier.py (Classifier): Use __SelectField()
56            to correctly set the table information and call this from
57            __init__ and from _OnFieldSelect so that all the information
58            is up to date when the dialog opens and when a field is changed.
59    
60    2003-03-10  Jonathan Coles   <[email protected]>
61    
62            * Thuban/Model/classification.py (Classification): Don't use
63            layer's message function directly, use the ClassChanged() method
64            when then classification changes. SetField/SetFieldType/SetLayer
65            must keep the information about field name and field type in
66            sync when an owning layer is set or removed.
67    
68            * Thuban/Model/layer.py: Added ClassChanged() so that the
69            classification can tell the layer when its data has changed.
70            (Layer.SetClassification): Accepts None as an arguement to
71            remove the current classification and correctly handles
72            adding a new classification.
73    
74            * Thuban/Model/load.py: Comment out print statement
75    
76            * test/test_classification.py, test/test_save.py: New and
77            improved tests.
78    
79    2003-03-07  Jonathan Coles   <[email protected]>
80    
81            * Thuban/Model/classification.py: Implemented __copy__ and
82            __deepcopy__ for ClassGroup* and ClassGroupProperites so
83            they can easily be copied by the classifier dialog.
84            (ClassGroupProperites.__init__): The default line color should
85            have been Color.Black.
86    
87            * Thuban/UI/classifier.py: Setting and Getting table values now
88            uses a consistent set of functions.
89            (Classifier): Now non-modal. Has field type label which changes
90            as the field changes. Keep track of buttons in a list so that
91            we can enable/disable the buttons when the None field is selected.
92            (SelectPropertiesDialog): Add buttons to make the colors transparent.
93    
94            * Thuban/UI/dialogs.py (NonModalDialog.Shutdown): New method which
95            does what OnClose did, but can be called by the application to
96            close a window. Needed when a session changes, and we have to
97            close the classifier windows.
98    
99            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
100            Shuts down open dialogs. Used when a new session is created
101            or a session is opened.
102            (MainWindow.SaveSession): Should only call application.SaveSession()
103            if we don't call SaveSessionAs first.
104            (MainWindow.Classify): Allow different classifier dialogs for
105            different layers.
106    
107            * Thuban/UI/tree.py (SessionTreeView): Remove OnClose and let
108            the parent class handle it. Add Shutdown() to unsubscibe from
109            event notification and call the parent Shutdown(). This was
110            necessary so the application can close the tree window.
111    
112    2003-03-06  Jonathan Coles   <[email protected]>
113    
114            * Thuban/Model/classification.py: Minor documentation changes,
115            Addition of __eq__ and __ne__ methods.
116            (Classification.SetLayer): prevent recursion between this method
117            and Layer.SetClassification().
118    
119            * Thuban/Model/color.py: Addition of __eq__ and __ne__ methods.
120    
121            * Thuban/Model/layer.py (SetClassification): prevent recursion
122            between this method and Classification.SetLayer().
123    
124            * test/test_classification.py, test/test_load.py,
125            test/test_session.py: Fixed and added tests for the classification
126            classes.
127    
128    2003-03-06  Bernhard Herzog  <[email protected]>
129    
130            * Thuban/UI/classifier.py (ClassGrid.__init__)
131            (ClassGrid.CreateTable): Move the SetSelectionMode call to
132            CreateTable because otherwise it triggers an assertion in
133            wxPython/wxGTK 2.4.
134    
135    2003-03-05  Jonathan Coles   <[email protected]>
136    
137            * Thuban/common.py: Move FIELDTYPE constants back to table.py.
138    
139            * Thuban/Model/load.py: import FIELDTYPE constants from table.
140    
141            * Thuban/UI/classifier.py: import FIELDTYPE constants from table.
142    
143            * Thuban/Model/table.py: Put FIELDTYPE constants back.
144    
145    2003-03-05  Jonathan Coles   <[email protected]>
146    
147            * Thuban/UI/classifier.py: Added class documentation.
148            Fixed RTbug #1713, #1714. Added Move[Up|Down] buttons.
149            Store just the groups in the table and generate the other
150            column information when it is requested. Add "None" field
151            to pull-down to select no classification.
152    
153            * Thuban/common.py: Moved FIELDTYPE constants from table.py
154            (Str2Num): Only catch ValueError exceptions.
155    
156            * Thuban/Model/classification.py: Class documentation. Renaming
157            of methods with Stroke to Line. Groups are stored in a single
158            list with the default as the first element. Groups are searched
159            in the order they appear in the list.
160    
161            * Thuban/Model/color.py: Documentation.
162    
163            * Thuban/Model/layer.py (Layer): Add GetFieldType to retreive
164            the kind of data represented by a field.
165    
166            * Thuban/Model/load.py (ProcessSession): Use proper string
167            conversion function; fixes RTbug #1713.
168

170    
171            * Thuban/Model/table.py: Put FIELDTYPE constants in common.py.
172            (Table): Add field_info_by_name() to retrieve field information
173            by specifying the field name, not the number.
174    
175            * Thuban/UI/mainwindow.py: Function name changes.
176    
177            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
178            get the layer classification once. Don't try to classify
179            values when the field is None: just use the default properties.
180    
181            * Thuban/UI/view.py: Function name changes.
182    
183            * Doc/thuban.dtd: Add field_type attribute to a classification.
184    
185    2003-03-04  Bernhard Herzog  <[email protected]>
186    
187            * Doc/thuban.dtd: Use correct syntax for optional attributes. Make
188            the fill and stroke layer attributes optional with suitable
189            default values. Add the stroke_width layer attribute. Use correct
190            syntax for empty elements. Make the attribute list for labels
191            refer to the label element.
192    
193    2003-03-04  Bernhard Herzog  <[email protected]>
194    
195            * setup.py (thuban_build_py.build): Add a comment about distutils in
196            Python 2.3 containing some of the functionality we implement in
197            setup.py ourselves.
198    
199            * Thuban/UI/classifier.py (ClassGrid.__init__): Set the table
200            before the selection mode. Doing it the other way round triggers
201            an assertion in wxWindows.
202    
203            * Thuban/Model/save.py (escape): Fix typo in doc-string
204    
205            * Thuban/Model/classification.py: Remove unnecessary wxPython
206            import
207    
208    2003-03-04  Jonathan Coles   <[email protected]>
209    
210            * Thuban/Model/classification.py (ClassGroupRange.GetProperties):
211            Parameter 'value' should default to None.
212    
213            * Thuban/UI/mainwindow.py: Use Layer.GetClassification() since
214            the class attribute __classification is now private.
215    
216            * Thuban/UI/classifier.py (ClassGrid): Moved OnCellDClick() from
217            Classifier to ClassGrid. Added support for removing selected rows,
218            which including code for keeping track of when cells are selected,
219            and deselected.
220            (ClassTable): Support for added/removing rows. Fixed a problem
221            with __ParseInput whereby it would not allow strings (only numbers)
222            to be entered.
223            (Classifier): Added button and supporting code for removing
224            selected rows.
225    
226    2003-02-27  Jonathan Coles   <[email protected]>
227    
228            * Thuban/common.py: Moved color conversion functions into
229            Thuban/UI/common.py.
230            (Str2Num): Now converts the float (not the string) to a long/int
231            so that an exception isn't thrown.
232    
233            * Thuban/UI/common.py: Common functions used in several UI modules
234    
235            * Thuban/Model/classification.py: Changed the class hierarchy
236            so that a Classification consists of Groups which return
237            Properties when a value matches a Group.
238    
239            * Thuban/Model/layer.py: Fixed name resolution problem.
240    
241            * Thuban/Model/load.py: Use new Classification and Group functions.
242    
243            * Thuban/Model/save.py (Saver.write_attribs): Fixes a test case
244            failure.
245            (Saver.write_classification): Use new Classification and Group
246            functions.
247    
248            * Thuban/UI/classifier.py: Changes to use new Classification and Group
249            functions. Fix to create a tuple with a single value instead of
250            simply returning the value.
251    
252            * Thuban/UI/renderer.py: Use new Classification and Group functions.
253            Use common.py functions.
254    
255            * Thuban/UI/tree.py: Use common.py functions.
256            
257            * test/test_classification.py: Use new Classification and Group
258            classes.
259

261    
262            * Thuban/common.py (Color2wxColour, wxColour2Color): Conversion
263            functions from Thuban color objects to wxWindow colour objects.
264    
265            * Thuban/Model/classification.py (Classification): Renamed
266            GetProperties() to GetClassData(). Used the new iterator
267            in TreeInfo().
268            (ClassIterator): Iterator implementation to iterate over the
269            ClassData objects in a classification object.
270    
271            * Thuban/Model/save.py (Saver.write_classificaton): Uses
272            the new iterator to save the classification information.
273    
274            * Thuban/UI/classifier.py (SelectPropertiesDialog): Support
275            for changing the stroke and fill colors and previewing the
276            changes.
277    
278            * Thuban/UI/mainwindow.py (MainWindow.OpenSession,
279            MainWindow.SaveSessionAs): Text string changes so the dialogs
280            have more meaningful titles.
281    
282            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Change
283            Classification method name from GetProperties to GetClassData.
284    
285            * Thuban/UI/view.py (MapCanvas.find_shape_at): Use method calls
286            instead of accessing now non-existent class variables.
287    
288    2003-02-24  Bernhard Herzog  <[email protected]>
289    
290            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Remove
291            unneeded Shape() call. Rendering is substantially faster without
292            it and it avoids some problems with broken shape files.
293    
294    2003-02-20  Frank Koormann   <[email protected]>
295    
296            Force minimal size of identify and label dialogs. The autosizing
297            looked too ugly.
298    
299            * Thuban/UI/controls.py (RecordListCtrl): Set minimal width for columns.
300            * Thuban/UI/labeldialog.py (LabelDialog.dialog_layout):

302            * Thuban/UI/identifyview.py (IdentifyView.__init__):
303            Set size of dialog.
304    
305    2003-02-19  Jonathan Coles   <[email protected]>
306

308            test/test_load.py, test/test_map.py, test/test_session.py:
309            Updated the tests to use the new functions that are in the
310            respective classes.
311    
312            * Thuban/Model/classification.py (Classification):

321    
322            * Thuban/Model/color.py: Added Color.None to represent something
323            with no color. Color.Black represents the color black.
324            (NoColor): Helper class derived from Color to represent something
325            with no color.
326    
327            * Thuban/Model/layer.py (Layer): Removed references to fill, stroke,
328            stroke_width attributes. Made the 'classification' attribute private.
329            New methods for setting/getting the classification.
330    
331            * Thuban/Model/load.py (ProcessSession): Use new methods on Layer
332            to get the classifcation and use the new ClassData* classes to
333            hold the classification data. Use Str2Num to convert numbers
334            properly.
335    
336            * Thuban/Model/save.py (Saver): Use new Color and Classification
337            methods
338    
339            * Thuban/UI/classifier.py (ClassGrid): New class to represent a
340            custom grid.
341            (ClassTable): Support for editing Values and Labels and for

348            (ClassPreviewer): Took the Draw method from ClassRenderer and
349            made most of it into this new class. Intend to use this class in
350            the SelectPropertiesDialog for previewing changes.
351    
352            * Thuban/UI/renderer.py: Use new Color and Classification methods.
353    
354            * Thuban/UI/tree.py: Formatting changes.
355    
356            * Doc/thuban.dtd: Add 'label' element
357

369    2003-02-11  Bernhard Herzog  <[email protected]>
370    
371            * Thuban/UI/application.py (ThubanApplication.splash_screen): New
372            method to create a splash screen.
373            (ThubanApplication.ShowMainWindow): New. Show the main window.
374            Needed so the splash screen can display the mainwindow
375            (ThubanApplication.OnInit): Call the
376            new splash_screen method to determine whether the application
377            should display a splash screen. If it displays a splash screen do
378            not immediately show the main window.
379    
380    2003-02-11  Jonathan Coles  <[email protected]>
381    
382            * Thuban/Model/classification.py: Added import line to fix
383            feature conflicts between running on python2.2 and python2.1.
384    
385            * Thuban/UI/classifier.py (ClassTable): Didn't need to hang
386            onto the clinfo parameter, so removed the deepcopy().
387    
388    2003-02-10  Jonathan Coles  <[email protected]>
389    
390            * Thuban/Model/save.py (Saver.open_element, Saver.close_element):
391            Added element_open variable to track opening and closing of tags
392            so that tags that don't span more than one line are closed with
393            /> instead of </tag_name>. Use the GetDefault*() methods of
394            the Classification class.
395    
396            * Thuban/Model/classification.py (Classificaton): Added set and
397            get methods for the default data. The class also takes a layer
398            reference so that modification messages can be sent. Fixed the
399            methods to use the new ClassData class.
400            (ClassData): New class to encapsulate the classification data
401    
402            * Thuban/Model/layer.py (Layer): Remove the
403            Set[Fill|Stroke|StrokeWidth]() methods. Code should call the
404            SetDefault*() methods on the layer's classification object.
405            (Layer.__init__): Use the new SetDefault*() methods in the
406            Classification class.

416            methods of the Classification class.
417    
418            * Thuban/UI/renderer.py (MapRenderer): Use the Get*() methods
419            of the ClassData class.

431            Layer.SetStrokeWidth): Modified these functions to change the
432            null data in the classification rather than keep these values
433            directly in the Layer class. Menu options to change these values
434            work again.
435

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

608            (MainWindow.set_position_text): Put the code that puts the text
609            with the mouse position into the status bar into the new method
610            set_position_text so that it can overwritten in derived classes.
611    
612    2002-09-12  Bernhard Herzog  <[email protected]>
613    
614            * Thuban/UI/mainwindow.py (MainWindow.RunMessageBox): Center the

616    
617    2002-09-11  Bernhard Herzog  <[email protected]>
618    
619            * Thuban/UI/mainwindow.py: Underline the 'x' in "Exit" instead of

621            entries.
622            (MainWindow.build_menu): remove an incorrect comment.
623    
624    2002-09-10  Bernhard Herzog  <[email protected]>

642    2002-09-02  Bernhard Herzog  <[email protected]>
643    
644            * Thuban/UI/view.py: Get rid of the idle redraw. This is done by
645            wxWindows already and our implementation doesn't work correctly
646            with wxGTK 2.3:
647            (MapCanvas.__init__): Remove the instance variable
648            (MapCanvas.OnPaint): Always call do_redraw when there's a map to
649            be drawin
650            (MapCanvas.OnIdle): Removed.
651    
652            * Thuban/UI/view.py (MapCanvas.unprojected_rect_around_point): Add
653            a parameter to determine the size of the rectangle.
654            (MapCanvas.find_shape_at): Create the box around the point on a
655            layer by layer basis and make the size depend on the shape type.
656            This solves a problem with the selection of point shapes at the
657            border of the layer's bounding box
658    
659    2002-08-30  Bernhard Herzog  <[email protected]>
660

684            arcs with multiple parts.
685    
686            * Thuban/UI/view.py (ZoomInTool.MouseUp, ZoomOutTool.MouseUp):
687            Handle degenrate rectangles.
688    
689            * Thuban/Model/table.py: Make writing records work correctly:
690            (Table.__init__): Keep track of whether the DBF is open for
691            writing
692            (Table.write_record): Open the DBF file for writing when necessary
693    
694    2002-08-27  Bernhard Herzog  <[email protected]>
695    
696            * Thuban/Model/table.py (Table.write_record, Table.__init__): Open
697            dbf files only for reading by default. Use a new writable dbf
698            object for writing.
699    
700    2002-08-26  Bernhard Herzog  <[email protected]>
701

708            layer table specific code from TableGrid into LayerTableGrid
709            (TableFrame, LayerTableFrame): Split the layer table specific code
710            from TableFrame into LayerTableFrame
711            (LayerTableGrid.select_shape): Remove a debug print
712    
713            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Use the
714            LayerTableFrame
715    
716    2002-08-23  Bernhard Herzog  <[email protected]>
717    
718            * Thuban/Model/layer.py (Layer.__init__): Make sure we have an
719            absolute filename.
720    
721    2002-08-22  Bernhard Herzog  <[email protected]>
722    
723            * Thuban/Model/table.py (Table.write_record): New method to write
724            records.

726    
727            * Thuban/UI/controls.py (RecordTable.SetValue): Write the value

732            commit any changes made to the DBF file.
733

735            (_tool_command): Put the code that generates the "checked"
736            callback into a separate function so that we can reuse it
737            elsewhere
738    
739            * Thuban/Model/save.py (Saver): New class to handle serializing a
740            session into an XML file. The main reason to introduce a class is
741            that applications built on Thuban can derive from it so that they
742            can save additional information in a session file.
743            (save_session): Delegate almost all the work to the Saver class.
744            Rename the filename argument to file because it may be a file like
745            object now.
746    
747            * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
748            code. Remove the little test code which would be executed when the
749            module is run as a script which didn't work anymore since it can't
750            import the other Thuban modules.
751            (ProcessSession, load_session): Refactor the ProcessSession to
752            have one method for each element start and end tag so that derived
753            classes can easily override the processing of individual tags.
754            Also, always parse with namespaces enabled because applications
755            built on top of Thuban will likely use namespaces if they extend
756            the session file format.
757    
758    2002-08-21  Bernhard Herzog  <[email protected]>
759    
760            * setup.py (ThubanInstall.run): Don't repr install_lib_orig
761            because thubaninit_contents will do it for us.
762    
763    2002-08-16  Jan-Oliver Wagner <[email protected]>
764    
765            * Thuban/UI/mainwindow.py: menu item 'show session tree' now disable if
766            tree window already open
767

776            * Thuban/Model/layer.py (Layer.Destroy): New. Explicitly close the
777            shapefile and destroy the table.
778

780    
781    2002-08-14  Bernhard Herzog  <[email protected]>
782    
783            * Thuban/UI/controls.py (RecordTable.__init__): Remove the unused
784            instance variable columns
785            (RecordTable.GetTypeName): row and col may be negative in some
786            cases.
787    
788            * setup.py (InstallLocal.initialize_options)
789            (InstallLocal.finalize_options, InstallLocal.user_options): New
790            option create-init-file to build a thubaninit.py when running
791            install_local
792            (InstallLocal.run): Create the thubaninit.py module when requested
793            (thubaninit_contents): Split the template into several parts and
794            create a new function thubaninit_contents that creates the
795            contents of a thubaninit module.
796            (ThubanInstall.run): Use the new function to create the thubaninit
797            module.
798

800    
801            * Thuban/UI/application.py (ThubanApplication.OnExit): Do some
802            cleanup.
803            (ThubanApplication.MainLoop): Extend to automatically call OnExit.
804    
805            * Thuban/Model/session.py (Session.Destroy): Don't bypass the
806            direct base class' Destroy method.
807    
808            * Thuban/Model/map.py (Map.ClearLayers): New method to delete all
809            layers.
810            (Map.Destroy): Destroy the label_layer as well and call the
