2    
3            * test/support.py (print_garbage_information): New function that
4            prints information about still connected messages and memory
5            leaks.
6            (run_suite): Removed.
7            (run_tests): New function for use as a replacement of
8            unittest.main in the test_* files. This one calls
9            print_garbage_information at the end.
10    
11            * test/runtests.py (main): Use support.print_garbage_information
12    
13            * test/test_layer.py: Use support.run_tests instead of
14            unittest.main so we get memory leak information
15            (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
16            (TestLayer.test_point_layer, TestLayer.test_empty_layer)
17            (TestLayerLegend.test_visibility): Call the layer's Destroy method
18            to fix a memory leak.
19    
20            * test/test_classification.py: Use support.run_tests instead of
21            unittest.main so we get memory leak information
22            (TestClassification.test_classification): Call the layer's Destroy
23            method to fix a memory leak.
24    
25    2003-04-02  Bernhard Herzog  <[email protected]>
26    
27            * extensions/thuban/wxproj.cpp (check_version, check_version_gtk):

29            PyArg_ParseTuple correctly.
30    
31            * Thuban/UI/application.py (ThubanApplication.OpenSession): Make

33            session again
34    
35            * Thuban/Model/table.py: Remove unnecessary import. Fix a typo.
36    
37    2003-04-01  Jonathan Coles   <[email protected]>

40            that there actually are points in the returned list of points
41            before trying to index into the list. The list may be empty if
42            the shape is a Null Shape.
43    
44    2003-04-01  Bernhard Herzog  <[email protected]>
45    
46            * test/test_map.py: Don't use from <module> import *
47    
48    2003-04-01  Jonathan Coles   <[email protected]>
49    
50            * Thuban/Model/session.py: Use LAYER_CHANGED instead of
51            LAYER_LEGEND_CHANGED

65            * Thuban/UI/dock.py (DockableWindow.UnDock): Restore size and
66            position (although position doesn't work yet under GTK).
67            (DockableWindow.Destroy): New. Called when the window must be
68            closed. Namely needed when the DockFrame closes and must close
69            its children.
70            (DockFrame): Listen for EVT_CLOSE and destroy all children.
71    
72            * Thuban/UI/legend.py (LegendPanel.Destroy): New. Cleans up

82    
83    2003-03-28  Jonathan Coles   <[email protected]>
84    
85            * Thuban/UI/classifier.py: Support for highlighting a specific
86            group within the grid when the classification dialog is opened.
87            Also contains a lot of debugging printouts which will later
88            be removed.
89    
90            * Thuban/UI/dock.py: Complete rework on the dock code so that
91            that it is fairly removed from the rest of the Thuban application.
92            It is easy to add new docks which the rest of the program having
93            to be aware of them.
94    
95            * Thuban/UI/legend.py: Modifications to support selecting a
96            specific group in the classification dialog. Changed how layers
97            are drawn when the layer is visible/invisible.

103            to check if scale > 0. Trying to track down a divide by zero.
104    
105    2003-03-26  Jonathan Coles   <[email protected]>
106    
107            * Thuban/UI/legend.py: Removed unnecessary LegendDialog class.
108            (LegendPanel): Removed _OnDock()/_OnUnDock() methods which are
109            now part of DockableWindow.

111            map.
112            (LegendTree._OnSelChanged): Call LegendPanel.DoOnSelChanged()
113            with the selected layer and/or group.
114    
115    2003-03-26  Jonathan Coles   <[email protected]>
116    
117            This putback contains the code for dockable windows. There is
118            no support in wxWindows as of this date for windows that can
119            attach themselves to other windows.
120    
121            The current model contains a DockableWindow which has a parent
122            window for when it is detached and a dock window that it puts
123            its contents in when it is docked. The contents of a DockableWindow
124            must be a DockPanel. DockPanel itself derives from wxPanel.
125    
126            * Thuban/Model/layer.py (Layer.ClassChanged): Send a LAYER_CHANGED
127            message, not a LAYER_LEGEND_CHANGED message.
128    
129            * Thuban/Model/map.py (Map): Forward LAYER_CHANGED messages.
130    
131            * Thuban/UI/classifier.py (Classifier.__init__): Use wxADJUST_MINSIZE
132            as one of the style properties for the fieldTypeText item to
133            be sure that its size is correct when the text changes.
134    
135            * Thuban/UI/dock.py: New. Classes for the DockPanel and
136            DockableWindow.
137    
138            * Thuban/UI/legend.py: Added some more buttons and made the
139            LegendPanel a DockPanel.
140    
141            * Thuban/UI/mainwindow.py: Added sash windows to the main window
142            and supporting functions for manipulating the sashes.
143            (MainWindow.ShowLegend): Create a DockableWindow with the
144            LegendPanel as the contents.
145    
146            * Thuban/UI/messages.py: Added DOCKABLE_* messages
147    
148            * Thuban/UI/view.py (MapCanves.SetMap): Listen for LAYER_CHANGED,
149            not LAYER_LEGEND_CHANGED, messages.
150    
151    2003-03-25  Jonathan Coles   <[email protected]>
152    
153            * setup.py: Added custom script bdist_rpm_build_script so that
154            when the rpm is built the path to wx-config is correct.
155    
156            * setup.cfg: Added line saying to use the custom build script
157    
158    2003-03-20  Jonathan Coles   <[email protected]>
159    
160            Initial implementation of the Legend.
161    
162            * Thuban/UI/legend.py: New. Creates a window that shows the map's
163            Legend information and allows the user to add/modify classifications
164            and how the layers are drawn on the map.
165    
166            * setup.py: New command 'build_docs' which currently uses
167            happydoc to generate html documentation for Thuban.
168    
169            * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
170            Returns a string which is appropriately describes the group.
171    
172            * Thuban/Model/layer.py (Layer.SetClassification): Generate a
173            LAYER_CHANGED event instead of a LAYER_LEGEND_CHANGED event.
174    
175            * Thuban/Model/map.py (Map): Rename messages and use new, more
176            specific, messages.
177    
178            * Thuban/Model/messages.py: New message to indicate that a layer's
179            data has changed (LAYER_CHANGED). New map messages to indicate
180            when layers have been added/removed/changed or if the stacking order
181            of the layers has changed.
182    
183            * Thuban/Model/session.py: Rename and use new messages.
184    
185            * Thuban/UI/classifier.py: Remember if any changes have actually
186            been applied so that if the dialog is cancelled without an application
187            of changes we don't have to set a new classification.
188            (ClassDataPreviewer): Pulled out the window specific code and put it
189            ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
190            symbols on any DC.
191            
192            * Thuban/UI/mainwindow.py: New code to open the legend.
193    
194            * Thuban/UI/view.py: Use new message names.
195    
196    2003-03-19  Jonathan Coles   <[email protected]>
197    
198            * Thuban/UI/main.py (verify_versions): New. Checks the versions
199            of Python, wxPython, and some other libraries.
200    
201            * extensions/thuban/wxproj.cpp (check_version): Checks the given
202            version against what wxproj was compiled with.
203            (check_version_gtk): If wxproj was compiled with gtk then check
204            the given version against the version of the gtk library
205            currently being used.
206    
207    2003-03-14  Bernhard Herzog  <[email protected]>
208    
209            * test/test_command.py: Run the tests when the module is run as a
210            script
211    
212    2003-03-14  Bernhard Herzog  <[email protected]>
213    
214            Implement selection of multiple selected shapes in the same layer:
215    
216            - Introduce a new class to hold the selection. This basically
217              replaces the interactor which was nothing more than the
218              selection anyway. A major difference is of course that the new
219              selection class supports multiple selected shapes in one layer
220            
221            - Move the object that represents the selection from the
222              application to the canvas. The canvas is a better place than the
223              application because the selection represents which shapes and
224              layer of the map displayed by the canvas are selected and
225              affects how the map is drawn.
226    
227            - Make the selection and its messages publicly available through
228              the mainwindow.
229    
230            - The non-modal dialogs do not get a reference to the interactor
231              anymore as they can simply refer to their parent, the
232              mainwindow, for the what the interactor had to offer.
233    
234            * Thuban/UI/selection.py: New module with a class to represent the
235            selection.
236    
237            * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
238            these unused messages
239    
240            * Thuban/UI/application.py (ThubanApplication.OnInit)
241            (ThubanApplication.OnExit, ThubanApplication.SetSession): The
242            interactor is gone now.
243            (ThubanApplication.CreateMainWindow): There is no interactor
244            anymore so we pass None as the interactor argument for now for
245            compatibility.
246    
247            * Thuban/UI/view.py (MapCanvas.delegated_messages)
248            (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
249            Unsubscribe, delegate messages according to the delegated_messages
250            class variable.
251            (MapCanvas.__getattr__, MapCanvas.delegated_methods): Get some
252            attributes from instance variables as described with the
253            delegated_methods class variable.
254            (MapCanvas.__init__): New instance variable selection holding the
255            current selection
256            (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
257            pass them on to the renderer
258            (MapCanvas.SetMap): Clear the selection when a different map is
259            selected.
260            (MapCanvas.shape_selected): Simple force a complete redraw. The
261            selection class now takes care of only issueing SHAPES_SELECTED
262            messages when the set of selected shapes actually does change.
263            (MapCanvas.SelectShapeAt): The selection is now managed in
264            self.selection
265    
266            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
267            (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
268            Unsubscribe, delegate messages according to the delegated_messages
269            class variable.
270            (MainWindow.delegated_methods, MainWindow.__getattr__): Get some
271            attributes from instance variables as described with the
272            delegated_methods class variable.
273            (MainWindow.__init__): The interactor as ivar is gone. The
274            parameter is still there for compatibility. The selection messages
275            now come from the canvas.
276            (MainWindow.current_layer, MainWindow.has_selected_layer):
277            Delegate to the the canvas.
278            (MainWindow.LayerShowTable, MainWindow.Classify)
279            (MainWindow.identify_view_on_demand): The dialogs don't need the
280            interactor parameter anymore.
281

283            (LayerTableFrame.__init__, LayerTableFrame.OnClose)
284            (LayerTableFrame.row_selected): The interactor is gone. It's job
285            from the dialog's point of view is now done by the mainwindow,
286            i.e. the parent. Subscribe to SHAPES_SELECTED instead
287            of SELECTED_SHAPE
288            
289            * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
290            is gone. It's job from the dialog's point of view is now done by
291            the mainwindow, i.e. the parent.
292            
293            * Thuban/UI/classifier.py (Classifier.__init__): The interactor is
294            gone. It's job from the dialog's point of view is now done by the
295            mainwindow, i.e. the parent.
296    
297            * Thuban/UI/tree.py (SessionTreeView.__init__): The interactor is
298            gone. It's job from the dialog's point of view is now done by the
299            mainwindow, i.e. the parent.
300            (SessionTreeCtrl.__init__): New parameter mainwindow which is
301            stored as self.mainwindow. The mainwindow is need so that the tree
302            can still subscribe to the selection messages.
303            (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
304            (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
305            selection is now accessible through the mainwindow. Subscribe to
306            SHAPES_SELECTED instead of SELECTED_SHAPE
307    
308            * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
309            SHAPES_SELECTED message now.
310            (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
311            so deal with multiple shapes
312            (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
313            gone. It's job from the dialog's point of view is now done by the
314            mainwindow, i.e. the parent.
315    
316            * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
317            parameter is now a list of shape ids.
318            (RecordTable.SetTable): The second parameter is now a list of
319            indices.
320    
321            * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the
322            selected_shape parameter and ivar to selected_shapes. It's now a
323            list of shape ids.
324            (MapRenderer.draw_label_layer): Deal with multiple selected
325            shapes. Rearrange the code a bit so that the setup and shape type
326            distinctions are only executed once.
327    
328            * test/test_selection.py: Test cases for the selection class
329    
330    2003-03-11  Jonathan Coles   <[email protected]>
331    
332            * Thuban/Model/load.py: Temporary fix so that the xml reader
333            doesn't cause Thuban to crash.
334    
335            * Thuban/Model/layer.py: Handle the cyclic references between
336            a layer and its classification better, and be sure to disconnect
337            the classification from the layer when the layer is destroyed
338            so that we don't maintain a cyclic reference that may not be
339            garbage collected.
340    
341            * Thuban/Model/classification.py: See comment for layer.py.
342

349    
350            * Thuban/UI/classifier.py: Add normal border to SelectPropertiesDialog.
351            Use True instead of true.
352            (Classifier): Should have a single panel in which all the controls lie.
353    
354            * Thuban/UI/proj4dialog.py: Add normal border.

364    
365    2003-03-10  Jonathan Coles   <[email protected]>
366    
367            * Thuban/UI/classifier.py (Classifier.__init__): Make the
368            field type label grow so that when the text changes the
369            size is updated correctly. This may be a wxWindows bug.
370    
371    2003-03-10  Jonathan Coles   <[email protected]>
372    
373            * Thuban/UI/application.py: Changed SESSION_CHANGED to

375    
376            * Thuban/UI/classifier.py: Wrap text with _().
377            (ClassGrid.CreateTable): Set dimensions and size hints here,
378            instead of in Reset, so we only set the size once.
379    
380            * Thuban/UI/dialogs.py: Don't need Shutdown(); just use Close()!
381    
382            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):

389    
390    2003-03-10  Jonathan Coles   <[email protected]>
391    
392            * Thuban/UI/classifier.py (Classifier): SelectField() needed
393            to know the old field index as well as the new one.
394    
395    2003-03-10  Jonathan Coles   <[email protected]>
396    
397            * Thuban/UI/classifier.py (Classifier): Use __SelectField()
398            to correctly set the table information and call this from
399            __init__ and from _OnFieldSelect so that all the information
400            is up to date when the dialog opens and when a field is changed.
401    
402    2003-03-10  Jonathan Coles   <[email protected]>
403    
404            * Thuban/Model/classification.py (Classification): Don't use
405            layer's message function directly, use the ClassChanged() method
406            when then classification changes. SetField/SetFieldType/SetLayer
407            must keep the information about field name and field type in
408            sync when an owning layer is set or removed.
409    
410            * Thuban/Model/layer.py: Added ClassChanged() so that the
411            classification can tell the layer when its data has changed.
412            (Layer.SetClassification): Accepts None as an arguement to
413            remove the current classification and correctly handles
414            adding a new classification.
415    
416            * Thuban/Model/load.py: Comment out print statement
417    
418            * test/test_classification.py, test/test_save.py: New and
419            improved tests.
420    
421    2003-03-07  Jonathan Coles   <[email protected]>
422    
423            * Thuban/Model/classification.py: Implemented __copy__ and
424            __deepcopy__ for ClassGroup* and ClassGroupProperites so
425            they can easily be copied by the classifier dialog.
426            (ClassGroupProperites.__init__): The default line color should
427            have been Color.Black.
428    
429            * Thuban/UI/classifier.py: Setting and Getting table values now
430            uses a consistent set of functions.
431            (Classifier): Now non-modal. Has field type label which changes
432            as the field changes. Keep track of buttons in a list so that
433            we can enable/disable the buttons when the None field is selected.
434            (SelectPropertiesDialog): Add buttons to make the colors transparent.
435    
436            * Thuban/UI/dialogs.py (NonModalDialog.Shutdown): New method which
437            does what OnClose did, but can be called by the application to
438            close a window. Needed when a session changes, and we have to
439            close the classifier windows.
440    
441            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
442            Shuts down open dialogs. Used when a new session is created
443            or a session is opened.
444            (MainWindow.SaveSession): Should only call application.SaveSession()
445            if we don't call SaveSessionAs first.
446            (MainWindow.Classify): Allow different classifier dialogs for
447            different layers.
448    
449            * Thuban/UI/tree.py (SessionTreeView): Remove OnClose and let
450            the parent class handle it. Add Shutdown() to unsubscibe from
451            event notification and call the parent Shutdown(). This was
452            necessary so the application can close the tree window.
453    
454    2003-03-06  Jonathan Coles   <[email protected]>
455    
456            * Thuban/Model/classification.py: Minor documentation changes,
457            Addition of __eq__ and __ne__ methods.
458            (Classification.SetLayer): prevent recursion between this method
459            and Layer.SetClassification().
460    
461            * Thuban/Model/color.py: Addition of __eq__ and __ne__ methods.
462    
463            * Thuban/Model/layer.py (SetClassification): prevent recursion
464            between this method and Classification.SetLayer().
465    
466            * test/test_classification.py, test/test_load.py,
467            test/test_session.py: Fixed and added tests for the classification
468            classes.
469    
470    2003-03-06  Bernhard Herzog  <[email protected]>
471    
472            * Thuban/UI/classifier.py (ClassGrid.__init__)
473            (ClassGrid.CreateTable): Move the SetSelectionMode call to
474            CreateTable because otherwise it triggers an assertion in
475            wxPython/wxGTK 2.4.
476    
477    2003-03-05  Jonathan Coles   <[email protected]>
478    
479            * Thuban/common.py: Move FIELDTYPE constants back to table.py.
480    
481            * Thuban/Model/load.py: import FIELDTYPE constants from table.
482    
483            * Thuban/UI/classifier.py: import FIELDTYPE constants from table.
484    
485            * Thuban/Model/table.py: Put FIELDTYPE constants back.
486    
487    2003-03-05  Jonathan Coles   <[email protected]>
488    
489            * Thuban/UI/classifier.py: Added class documentation.
490            Fixed RTbug #1713, #1714. Added Move[Up|Down] buttons.
491            Store just the groups in the table and generate the other
492            column information when it is requested. Add "None" field
493            to pull-down to select no classification.
494    
495            * Thuban/common.py: Moved FIELDTYPE constants from table.py
496            (Str2Num): Only catch ValueError exceptions.
497    
498            * Thuban/Model/classification.py: Class documentation. Renaming
499            of methods with Stroke to Line. Groups are stored in a single
500            list with the default as the first element. Groups are searched
501            in the order they appear in the list.
502    
503            * Thuban/Model/color.py: Documentation.
504    
505            * Thuban/Model/layer.py (Layer): Add GetFieldType to retreive
506            the kind of data represented by a field.
507    
508            * Thuban/Model/load.py (ProcessSession): Use proper string
509            conversion function; fixes RTbug #1713.

516    
517            * Thuban/UI/mainwindow.py: Function name changes.
518    
519            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
520            get the layer classification once. Don't try to classify
521            values when the field is None: just use the default properties.
522    
523            * Thuban/UI/view.py: Function name changes.
524    
525            * Doc/thuban.dtd: Add field_type attribute to a classification.
526    
527    2003-03-04  Bernhard Herzog  <[email protected]>
528    
529            * Doc/thuban.dtd: Use correct syntax for optional attributes. Make
530            the fill and stroke layer attributes optional with suitable
531            default values. Add the stroke_width layer attribute. Use correct
532            syntax for empty elements. Make the attribute list for labels
533            refer to the label element.
534    
535    2003-03-04  Bernhard Herzog  <[email protected]>
536    
537            * setup.py (thuban_build_py.build): Add a comment about distutils in
538            Python 2.3 containing some of the functionality we implement in
539            setup.py ourselves.
540    
541            * Thuban/UI/classifier.py (ClassGrid.__init__): Set the table
542            before the selection mode. Doing it the other way round triggers
543            an assertion in wxWindows.
544    
545            * Thuban/Model/save.py (escape): Fix typo in doc-string
546    
547            * Thuban/Model/classification.py: Remove unnecessary wxPython
548            import
549    
550    2003-03-04  Jonathan Coles   <[email protected]>

553            Parameter 'value' should default to None.
554    
555            * Thuban/UI/mainwindow.py: Use Layer.GetClassification() since
556            the class attribute __classification is now private.
557    
558            * Thuban/UI/classifier.py (ClassGrid): Moved OnCellDClick() from
559            Classifier to ClassGrid. Added support for removing selected rows,
560            which including code for keeping track of when cells are selected,
561            and deselected.
562            (ClassTable): Support for added/removing rows. Fixed a problem
563            with __ParseInput whereby it would not allow strings (only numbers)
564            to be entered.
565            (Classifier): Added button and supporting code for removing
566            selected rows.
567    
568    2003-02-27  Jonathan Coles   <[email protected]>
569    
570            * Thuban/common.py: Moved color conversion functions into
571            Thuban/UI/common.py.
572            (Str2Num): Now converts the float (not the string) to a long/int
573            so that an exception isn't thrown.
574    
575            * Thuban/UI/common.py: Common functions used in several UI modules
576    
577            * Thuban/Model/classification.py: Changed the class hierarchy
578            so that a Classification consists of Groups which return
579            Properties when a value matches a Group.

584    
585            * Thuban/Model/save.py (Saver.write_attribs): Fixes a test case
586            failure.
587            (Saver.write_classification): Use new Classification and Group
588            functions.
589    
590            * Thuban/UI/classifier.py: Changes to use new Classification and Group
591            functions. Fix to create a tuple with a single value instead of
592            simply returning the value.
593    
594            * Thuban/UI/renderer.py: Use new Classification and Group functions.
595            Use common.py functions.
596    
597            * Thuban/UI/tree.py: Use common.py functions.
598            
599            * test/test_classification.py: Use new Classification and Group
600            classes.

623    
624            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Change
625            Classification method name from GetProperties to GetClassData.
626    
627            * Thuban/UI/view.py (MapCanvas.find_shape_at): Use method calls
628            instead of accessing now non-existent class variables.
629    
630    2003-02-24  Bernhard Herzog  <[email protected]>
631    
632            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Remove
633            unneeded Shape() call. Rendering is substantially faster without
634            it and it avoids some problems with broken shape files.
635    
636    2003-02-20  Frank Koormann   <[email protected]>
637    
638            Force minimal size of identify and label dialogs. The autosizing
639            looked too ugly.
640    
641            * Thuban/UI/controls.py (RecordListCtrl): Set minimal width for columns.
642            * Thuban/UI/labeldialog.py (LabelDialog.dialog_layout):

667            with no color.
668    
669            * Thuban/Model/layer.py (Layer): Removed references to fill, stroke,
670            stroke_width attributes. Made the 'classification' attribute private.
671            New methods for setting/getting the classification.
672    
673            * Thuban/Model/load.py (ProcessSession): Use new methods on Layer
674            to get the classifcation and use the new ClassData* classes to
675            hold the classification data. Use Str2Num to convert numbers
676            properly.
677    
678            * Thuban/Model/save.py (Saver): Use new Color and Classification
679            methods
680

726    
727            * Thuban/UI/classifier.py (ClassTable): Didn't need to hang
728            onto the clinfo parameter, so removed the deepcopy().
729    
730    2003-02-10  Jonathan Coles  <[email protected]>
731    
732            * Thuban/Model/save.py (Saver.open_element, Saver.close_element):
733            Added element_open variable to track opening and closing of tags
734            so that tags that don't span more than one line are closed with
735            /> instead of </tag_name>. Use the GetDefault*() methods of
736            the Classification class.
737    
738            * Thuban/Model/classification.py (Classificaton): Added set and
739            get methods for the default data. The class also takes a layer
740            reference so that modification messages can be sent. Fixed the
741            methods to use the new ClassData class.
742            (ClassData): New class to encapsulate the classification data
743    
744            * Thuban/Model/layer.py (Layer): Remove the

754            draw the classifications in the dialog box's table.
755            (Classifier): Modified to use the ClassRenderer class.
756    
757            * Thuban/UI/mainwindow.py (MainWindow): Use the SetDefault*()
758            methods of the Classification class.
759    
760            * Thuban/UI/renderer.py (MapRenderer): Use the Get*() methods
761            of the ClassData class.
762    
763            * test/test_classification.py, test/test_layer.py,
764            test/test_map.py, test/test_session.py: Fix the tests to work
765            with the above code changes.
766    
767    2003-02-03  Jonathan Coles  <[email protected]>

771    
772            * Thuban/Model/layer.py (Layer.SetFill, Layer.SetStroke,
773            Layer.SetStrokeWidth): Modified these functions to change the
774            null data in the classification rather than keep these values
775            directly in the Layer class. Menu options to change these values
776            work again.
777    
778    2003-01-28  Jonathan Coles  <[email protected]>
779    
780            * Thuban/UI/classifier.py (Classifier): Resolved merging conflicts.
781            Fixed crashing problem on some systems. Dialog box shows

785            Colors in the tree view.
786    
787            * Thuban/Model/layer.py (Layer.TreeInfo): Added a call to build
788            the tree info for classifications. Commented out unnecessary lines.

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

951            with the mouse position into the status bar into the new method
952            set_position_text so that it can overwritten in derived classes.
953    
954    2002-09-12  Bernhard Herzog  <[email protected]>
955    
956            * Thuban/UI/mainwindow.py (MainWindow.RunMessageBox): Center the
957            message box on the main window.
958

960    
961            * Thuban/UI/mainwindow.py: Underline the 'x' in "Exit" instead of
962            the 'E' because it's less likely to interfere with other menu
963            entries.
964            (MainWindow.build_menu): remove an incorrect comment.
965    
966    2002-09-10  Bernhard Herzog  <[email protected]>

983    
984    2002-09-02  Bernhard Herzog  <[email protected]>
985    
986            * Thuban/UI/view.py: Get rid of the idle redraw. This is done by
987            wxWindows already and our implementation doesn't work correctly
988            with wxGTK 2.3:
989            (MapCanvas.__init__): Remove the instance variable
990            (MapCanvas.OnPaint): Always call do_redraw when there's a map to
991            be drawin

995            a parameter to determine the size of the rectangle.
996            (MapCanvas.find_shape_at): Create the box around the point on a
997            layer by layer basis and make the size depend on the shape type.
998            This solves a problem with the selection of point shapes at the
999            border of the layer's bounding box
1000    
1001    2002-08-30  Bernhard Herzog  <[email protected]>

1028            * Thuban/UI/view.py (ZoomInTool.MouseUp, ZoomOutTool.MouseUp):
1029            Handle degenrate rectangles.
1030    
1031            * Thuban/Model/table.py: Make writing records work correctly:

1035    
1036    2002-08-27  Bernhard Herzog  <[email protected]>
1037    
1038            * Thuban/Model/table.py (Table.write_record, Table.__init__): Open
1039            dbf files only for reading by default. Use a new writable dbf
1040            object for writing.
1041    
1042    2002-08-26  Bernhard Herzog  <[email protected]>

1050            layer table specific code from TableGrid into LayerTableGrid
1051            (TableFrame, LayerTableFrame): Split the layer table specific code
1052            from TableFrame into LayerTableFrame
1053            (LayerTableGrid.select_shape): Remove a debug print
1054    
1055            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Use the
1056            LayerTableFrame
1057    
1058    2002-08-23  Bernhard Herzog  <[email protected]>
1059    
1060            * Thuban/Model/layer.py (Layer.__init__): Make sure we have an
1061            absolute filename.

1074            commit any changes made to the DBF file.
1075    
1076            * Thuban/UI/mainwindow.py (make_check_current_tool)
1077            (_tool_command): Put the code that generates the "checked"
1078            callback into a separate function so that we can reuse it
1079            elsewhere
1080    
1081            * Thuban/Model/save.py (Saver): New class to handle serializing a
1082            session into an XML file. The main reason to introduce a class is
1083            that applications built on Thuban can derive from it so that they
1084            can save additional information in a session file.
1085            (save_session): Delegate almost all the work to the Saver class.
1086            Rename the filename argument to file because it may be a file like
1087            object now.
1088    
1089            * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
1090            code. Remove the little test code which would be executed when the
1091            module is run as a script which didn't work anymore since it can't
1092            import the other Thuban modules.
1093            (ProcessSession, load_session): Refactor the ProcessSession to
1094            have one method for each element start and end tag so that derived
1095            classes can easily override the processing of individual tags.
1096            Also, always parse with namespaces enabled because applications
1097            built on top of Thuban will likely use namespaces if they extend
1098            the session file format.
1099    
1100    2002-08-21  Bernhard Herzog  <[email protected]>
1101    
1102            * setup.py (ThubanInstall.run): Don't repr install_lib_orig
1103            because thubaninit_contents will do it for us.
1104

1106    
1107            * Thuban/UI/mainwindow.py: menu item 'show session tree' now disable if
1108            tree window already open
1109

1116            when we have actually captured it.
1117    
1118            * Thuban/Model/layer.py (Layer.Destroy): New. Explicitly close the
1119            shapefile and destroy the table.
1120    
1121            * Thuban/Model/table.py (Table.Destroy): New. Close the DBF file.
1122    
1123    2002-08-14  Bernhard Herzog  <[email protected]>
1124    
1125            * Thuban/UI/controls.py (RecordTable.__init__): Remove the unused
1126            instance variable columns
1127            (RecordTable.GetTypeName): row and col may be negative in some
1128            cases.
1129    
1130            * setup.py (InstallLocal.initialize_options)
1131            (InstallLocal.finalize_options, InstallLocal.user_options): New
1132            option create-init-file to build a thubaninit.py when running
1133            install_local
1134            (InstallLocal.run): Create the thubaninit.py module when requested
1135            (thubaninit_contents): Split the template into several parts and
1136            create a new function thubaninit_contents that creates the
1137            contents of a thubaninit module.
1138            (ThubanInstall.run): Use the new function to create the thubaninit
1139            module.

1151            layers.
1152            (Map.Destroy): Destroy the label_layer as well and call the
1153            inherited Desatroymethod first so that no more messages are

1156            message if the stacking order actually has changed. Add
1157            doc-strings.
