11    
12            Since we now say that the order of the groups in a classification
13            matters, it makes sense to be able to manipulate that order. Most
14            of the changes to Thuban/Model/classification.py are to that end.
15    
16            * Thuban/Model/classification.py (Classification.AppendGroup,
17            Classification.InsertGroup, Classification.ReplaceGroup,
18            Classification.RemoveGroup, Classification.GetGroup): Do as the
19            names imply.
20            (Classification.FindGroup): This was called GetGroup, but GetGroup
21            takes an index, while FindGroup takes a value.
22            (Classification.__deepcopy__): Copy all the groups, BUT NOT THE LAYER
23            REFERENCE. Currently there is a cyclic reference between the layer
24            and its classification. If the classification doesn't need to know
25            its owning layer we can change this, since it may make sense to be
26            able to use the same classification with different layers.
27    
28            * Thuban/Model/load.py: Use Classification.AppendGroup(), not AddGroup()
29    
30            * Thuban/UI/classgen.py: Use Classification.AppendGroup(),
31            not AddGroup()
32    
33            * Thuban/UI/classifier.py: Now that we can depend on the order in
34            a Classification and have methods to manipulate that order we don't
35            need to use our own data structures in the grid. We can simply make
36            the grid/table access the information they need from a copy of
37            the classification object.
38            (Classifier._OnCloseBtn): Event handler for when the user clicks
39            'Close'. This is needed so if the user applies changes and then
40            continues to change the table the user has the option of discarding
41            the most recent changes and keeping what they applied.
42    
43            * Thuban/UI/mainwindow.py: Put "Show Legend" and "Show Session Tree"
44            into the same group.
45    
46            * extensions/thuban/wxproj.cpp (check_version): If Thuban is compiled
47            with a really old version of proj, PJ_VERSION won't even be defined.
48            If it isn't defined then just compile so that the function always
49            returns Py_False.
50    
51            * test/test_classification.py: Fix tests to use the renamed methods.
52            Still need to write tests for the new methods.
53    
54    2003-04-04  Jonathan Coles   <[email protected]>
55    
56            * Thuban/UI/classifier.py (Classifier.__SelectField): Move the
57            call to SetSelection out of the method and before the call
58            to __SelectField in __init__. This prevents a recursion of events
59            when _OnFieldSelect is triggered by the user.
60    
61    2003-04-04  Jonathan Coles   <[email protected]>
62    
63            * Thuban/Model/classification.py: Rename Color.None to
64            Color.Transparent.
65            (ClassGroupProperties.SetLineColori, ClassGroupProperties.SetFill):
66            Don't bother copying the color, since Colors are immutable.
67    
68            * Thuban/Model/color.py, Thuban/Model/layer.py, Thuban/Model/load.py,
69            Thuban/UI/classifier.py, Thuban/UI/mainwindow.py,
70            Thuban/UI/renderer.py, Thuban/UI/view.py:
71            Rename Color.None to Color.Transparent.
72        
73            * test/test_classification.py, test/test_load.py: Rename Color.None
74            to Color.Transparent.
75    
76    2003-04-04  Jonathan Coles   <[email protected]>
77    
78            * Thuban/Model/classification.py: Fix assert calls.
79            (ClassGroupProperties.SetLineColor, ClassGroupProperties.SetFill):
80            Copy the color parameter rather than hold onto a reference.
81    
82            * Thuban/Model/color.py (Color.__copy__, Color.__deepcopy): Copy
83            the color object.
84            (NoColor.__copy__, NoColor.__deepcopy): Return 'self' so that we
85            are sure there exists only one refernce to Color.None in the system.
86            This allows us to use 'is' rather than the comparision functions.
87            
88            * Thuban/Model/save.py: Fix assert calls.
89            
90            * Thuban/UI/classifier.py: Fix assert calls.
91            (ClassGrid._OnCellDClick): Call up to the classifier to open the
92            dialog to edit the groups properties.
93            (ClassGrid._OnCellResize): Make sure that the scollbars are drawn
94            correctly if a cell is resized.
95            (ClassTable.SetClassification): New. Changes the classification
96            that is in the table.
97            (ClassTable.__SetRow): Allow groups to be prepended.
98            (Classifier): New code for opening the EditProperties and
99            GenerateRanges dialogs.
100            (SelectPropertiesDialog.__GetColor): Only set the color in the
101            color dialog if the current color is not None.
102            
103            * Thuban/UI/dock.py: Fix assert calls.
104            
105            * Thuban/UI/legend.py: Fix assert calls.
106            
107            * Thuban/UI/renderer.py: Fix assert calls.
108            
109            * Thuban/UI/classgen.py (ClassGenDialog): Dialog for generating
110            classifications.
111            (GenRangePanel): Panel specific to range generation.
112            (GenSingletonPanel): Panel specific to singleton generation.
113            (ClassGenerator): Class responsible for actually generating
114            the classification from the data gathered in the dialog box.
115            (PropertyRamp): Generates properties whose values range from
116            a starting property to an ending property.
117    
118    2003-04-03  Bernhard Herzog  <[email protected]>
119    
120            * test/support.py (print_garbage_information): New function that
121            prints information about still connected messages and memory
122            leaks.
123            (run_suite): Removed.
124            (run_tests): New function for use as a replacement of
125            unittest.main in the test_* files. This one calls
126            print_garbage_information at the end.
127    
128            * test/runtests.py (main): Use support.print_garbage_information
129    
130            * test/test_layer.py: Use support.run_tests instead of
131            unittest.main so we get memory leak information
132            (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
133            (TestLayer.test_point_layer, TestLayer.test_empty_layer)
134            (TestLayerLegend.test_visibility): Call the layer's Destroy method
135            to fix a memory leak.
136    
137            * test/test_classification.py: Use support.run_tests instead of
138            unittest.main so we get memory leak information
139            (TestClassification.test_classification): Call the layer's Destroy
140            method to fix a memory leak.
141    
142    2003-04-02  Bernhard Herzog  <[email protected]>
143    
144            * extensions/thuban/wxproj.cpp (check_version, check_version_gtk):
145            Handle the reference counts of the return value and errors in
146            PyArg_ParseTuple correctly.
147    
148            * Thuban/UI/application.py (ThubanApplication.OpenSession): Make
149            sure the filename is absolute to avoid problems when saving the
150            session again
151    
152            * Thuban/Model/table.py: Remove unnecessary import. Fix a typo.
153    
154    2003-04-01  Jonathan Coles   <[email protected]>
155    
156            *  Thuban/UI/renderer.py (MapRenderer.draw_point_shape): Check
157            that there actually are points in the returned list of points
158            before trying to index into the list. The list may be empty if
159            the shape is a Null Shape.
160    
161    2003-04-01  Bernhard Herzog  <[email protected]>
162    
163            * test/test_map.py: Don't use from <module> import *

166    
167            * Thuban/Model/session.py: Use LAYER_CHANGED instead of
168            LAYER_LEGEND_CHANGED
169    
170            * Thuban/UI/dock.py (DockableWindow._OnButtonClose): Call
171            self.Destroy() to close the window after yesterday's changes.

179            (ClassDataPreviewer.Draw): Draw rectangles for polygon layers per
180            RTbug #1769.
181    
182            * Thuban/UI/dock.py (DockableWindow.UnDock): Restore size and
183            position (although position doesn't work yet under GTK).
184            (DockableWindow.Destroy): New. Called when the window must be
185            closed. Namely needed when the DockFrame closes and must close
186            its children.
187            (DockFrame): Listen for EVT_CLOSE and destroy all children.
188    
189            * Thuban/UI/legend.py (LegendPanel.Destroy): New. Cleans up
190            when then window is told to close.
191            (LegendTree._OnMsgLayerChanged): Fixes a seg fault bug. See
192            comment in source for more info.
193    
194            * Thuban/UI/main.py: Show the legend by default when Thuban starts.
195    
196            * Thuban/UI/mainwindow.py: Renamed OnClose to _OnClose for
197            symmetry with other such methods.
198            (MainWindow.ShowLegend): Show the legend docked by default.
199    
200    2003-03-28  Jonathan Coles   <[email protected]>
201    
202            * Thuban/UI/classifier.py: Support for highlighting a specific
203            group within the grid when the classification dialog is opened.
204            Also contains a lot of debugging printouts which will later
205            be removed.
206    
207            * Thuban/UI/dock.py: Complete rework on the dock code so that
208            that it is fairly removed from the rest of the Thuban application.
209            It is easy to add new docks which the rest of the program having
210            to be aware of them.
211    
212            * Thuban/UI/legend.py: Modifications to support selecting a
213            specific group in the classification dialog. Changed how layers
214            are drawn when the layer is visible/invisible.
215    
216            * Thuban/UI/mainwindow.py: Removed legend specific code and
217            replaced it with calls to the new dock code.
218    
219            * Thuban/UI/renderer.py (MapRenderer.__init__): Added assert
220            to check if scale > 0. Trying to track down a divide by zero.
221    
222    2003-03-26  Jonathan Coles   <[email protected]>
223    
224            * Thuban/UI/legend.py: Removed unnecessary LegendDialog class.
225            (LegendPanel): Removed _OnDock()/_OnUnDock() methods which are
226            now part of DockableWindow.
227            (LegendPanel.DoOnSelChanged): Select the current layer in the
228            map.
229            (LegendTree._OnSelChanged): Call LegendPanel.DoOnSelChanged()
230            with the selected layer and/or group.
231    
232    2003-03-26  Jonathan Coles   <[email protected]>
233    
234            This putback contains the code for dockable windows. There is
235            no support in wxWindows as of this date for windows that can
236            attach themselves to other windows.
237    
238            The current model contains a DockableWindow which has a parent
239            window for when it is detached and a dock window that it puts
240            its contents in when it is docked. The contents of a DockableWindow
241            must be a DockPanel. DockPanel itself derives from wxPanel.
242    
243            * Thuban/Model/layer.py (Layer.ClassChanged): Send a LAYER_CHANGED
244            message, not a LAYER_LEGEND_CHANGED message.
245    
246            * Thuban/Model/map.py (Map): Forward LAYER_CHANGED messages.
247    
248            * Thuban/UI/classifier.py (Classifier.__init__): Use wxADJUST_MINSIZE
249            as one of the style properties for the fieldTypeText item to
250            be sure that its size is correct when the text changes.
251    
252            * Thuban/UI/dock.py: New. Classes for the DockPanel and
253            DockableWindow.
254    
255            * Thuban/UI/legend.py: Added some more buttons and made the
256            LegendPanel a DockPanel.
257    
258            * Thuban/UI/mainwindow.py: Added sash windows to the main window
259            and supporting functions for manipulating the sashes.
260            (MainWindow.ShowLegend): Create a DockableWindow with the
261            LegendPanel as the contents.
262    
263            * Thuban/UI/messages.py: Added DOCKABLE_* messages
264    
265            * Thuban/UI/view.py (MapCanves.SetMap): Listen for LAYER_CHANGED,
266            not LAYER_LEGEND_CHANGED, messages.
267    
268    2003-03-25  Jonathan Coles   <[email protected]>
269    
270            * setup.py: Added custom script bdist_rpm_build_script so that
271            when the rpm is built the path to wx-config is correct.
272    
273            * setup.cfg: Added line saying to use the custom build script
274    
275    2003-03-20  Jonathan Coles   <[email protected]>
276    
277            Initial implementation of the Legend.
278    
279            * Thuban/UI/legend.py: New. Creates a window that shows the map's
280            Legend information and allows the user to add/modify classifications
281            and how the layers are drawn on the map.
282    
283            * setup.py: New command 'build_docs' which currently uses
284            happydoc to generate html documentation for Thuban.
285    
286            * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
287            Returns a string which is appropriately describes the group.
288    
289            * Thuban/Model/layer.py (Layer.SetClassification): Generate a
290            LAYER_CHANGED event instead of a LAYER_LEGEND_CHANGED event.
291    
292            * Thuban/Model/map.py (Map): Rename messages and use new, more
293            specific, messages.
294    
295            * Thuban/Model/messages.py: New message to indicate that a layer's
296            data has changed (LAYER_CHANGED). New map messages to indicate
297            when layers have been added/removed/changed or if the stacking order
298            of the layers has changed.
299    
300            * Thuban/Model/session.py: Rename and use new messages.
301    
302            * Thuban/UI/classifier.py: Remember if any changes have actually
303            been applied so that if the dialog is cancelled without an application
304            of changes we don't have to set a new classification.
305            (ClassDataPreviewer): Pulled out the window specific code and put it
306            ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
307            symbols on any DC.
308            
309            * Thuban/UI/mainwindow.py: New code to open the legend.
310    
311            * Thuban/UI/view.py: Use new message names.
312    
313    2003-03-19  Jonathan Coles   <[email protected]>
314    
315            * Thuban/UI/main.py (verify_versions): New. Checks the versions
316            of Python, wxPython, and some other libraries.
317    
318            * extensions/thuban/wxproj.cpp (check_version): Checks the given
319            version against what wxproj was compiled with.
320            (check_version_gtk): If wxproj was compiled with gtk then check
321            the given version against the version of the gtk library
322            currently being used.
323    
324    2003-03-14  Bernhard Herzog  <[email protected]>
325    
326            * test/test_command.py: Run the tests when the module is run as a
327            script
328    
329    2003-03-14  Bernhard Herzog  <[email protected]>
330    
331            Implement selection of multiple selected shapes in the same layer:
332    
333            - Introduce a new class to hold the selection. This basically
334              replaces the interactor which was nothing more than the
335              selection anyway. A major difference is of course that the new
336              selection class supports multiple selected shapes in one layer
337            
338            - Move the object that represents the selection from the
339              application to the canvas. The canvas is a better place than the
340              application because the selection represents which shapes and
341              layer of the map displayed by the canvas are selected and
342              affects how the map is drawn.
343    
344            - Make the selection and its messages publicly available through
345              the mainwindow.
346    
347            - The non-modal dialogs do not get a reference to the interactor
348              anymore as they can simply refer to their parent, the
349              mainwindow, for the what the interactor had to offer.
350    
351            * Thuban/UI/selection.py: New module with a class to represent the
352            selection.
353    
354            * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
355            these unused messages
356    
357            * Thuban/UI/application.py (ThubanApplication.OnInit)
358            (ThubanApplication.OnExit, ThubanApplication.SetSession): The
359            interactor is gone now.
360            (ThubanApplication.CreateMainWindow): There is no interactor
361            anymore so we pass None as the interactor argument for now for
362            compatibility.
363    
364            * Thuban/UI/view.py (MapCanvas.delegated_messages)
365            (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
366            Unsubscribe, delegate messages according to the delegated_messages
367            class variable.
368            (MapCanvas.__getattr__, MapCanvas.delegated_methods): Get some
369            attributes from instance variables as described with the
370            delegated_methods class variable.
371            (MapCanvas.__init__): New instance variable selection holding the
372            current selection
373            (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
374            pass them on to the renderer
375            (MapCanvas.SetMap): Clear the selection when a different map is
376            selected.
377            (MapCanvas.shape_selected): Simple force a complete redraw. The
378            selection class now takes care of only issueing SHAPES_SELECTED
379            messages when the set of selected shapes actually does change.
380            (MapCanvas.SelectShapeAt): The selection is now managed in
381            self.selection
382    
383            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
384            (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
385            Unsubscribe, delegate messages according to the delegated_messages
386            class variable.
387            (MainWindow.delegated_methods, MainWindow.__getattr__): Get some
388            attributes from instance variables as described with the
389            delegated_methods class variable.
390            (MainWindow.__init__): The interactor as ivar is gone. The
391            parameter is still there for compatibility. The selection messages
392            now come from the canvas.
393            (MainWindow.current_layer, MainWindow.has_selected_layer):
394            Delegate to the the canvas.
395            (MainWindow.LayerShowTable, MainWindow.Classify)
396            (MainWindow.identify_view_on_demand): The dialogs don't need the
397            interactor parameter anymore.
398    
399            * Thuban/UI/tableview.py (TableFrame.__init__)
400            (LayerTableFrame.__init__, LayerTableFrame.OnClose)
401            (LayerTableFrame.row_selected): The interactor is gone. It's job
402            from the dialog's point of view is now done by the mainwindow,
403            i.e. the parent. Subscribe to SHAPES_SELECTED instead
404            of SELECTED_SHAPE
405            
406            * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
407            is gone. It's job from the dialog's point of view is now done by

410            * Thuban/UI/classifier.py (Classifier.__init__): The interactor is
411            gone. It's job from the dialog's point of view is now done by the
412            mainwindow, i.e. the parent.
413    
414            * Thuban/UI/tree.py (SessionTreeView.__init__): The interactor is
415            gone. It's job from the dialog's point of view is now done by the
416            mainwindow, i.e. the parent.
417            (SessionTreeCtrl.__init__): New parameter mainwindow which is
418            stored as self.mainwindow. The mainwindow is need so that the tree
419            can still subscribe to the selection messages.
420            (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
421            (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
422            selection is now accessible through the mainwindow. Subscribe to
423            SHAPES_SELECTED instead of SELECTED_SHAPE
424    
425            * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
426            SHAPES_SELECTED message now.
427            (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
428            so deal with multiple shapes
429            (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
430            gone. It's job from the dialog's point of view is now done by the
431            mainwindow, i.e. the parent.
432    
433            * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
434            parameter is now a list of shape ids.
435            (RecordTable.SetTable): The second parameter is now a list of
436            indices.
437    
438            * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the
439            selected_shape parameter and ivar to selected_shapes. It's now a
440            list of shape ids.
441            (MapRenderer.draw_label_layer): Deal with multiple selected
442            shapes. Rearrange the code a bit so that the setup and shape type
443            distinctions are only executed once.
444    
445            * test/test_selection.py: Test cases for the selection class
446    
447    2003-03-11  Jonathan Coles   <[email protected]>
448    
449            * Thuban/Model/load.py: Temporary fix so that the xml reader
450            doesn't cause Thuban to crash.
451    
452            * Thuban/Model/layer.py: Handle the cyclic references between
453            a layer and its classification better, and be sure to disconnect
454            the classification from the layer when the layer is destroyed
455            so that we don't maintain a cyclic reference that may not be
456            garbage collected.
457    
458            * Thuban/Model/classification.py: See comment for layer.py.
459    
460    2003-03-12  Jan-Oliver Wagner <[email protected]>
461    
462            * HOWTO-Release: New. Information on the steps for releasing
463            a new version of Thuban.
464    
465    2003-03-11  Jonathan Coles   <[email protected]>
466    
467            * Thuban/UI/classifier.py: Add normal border to SelectPropertiesDialog.
468            Use True instead of true.
469            (Classifier): Should have a single panel in which all the controls lie.
470    
471            * Thuban/UI/proj4dialog.py: Add normal border.
472    
473            * Thuban/UI/tree.py: Fixed problem with bad item images under Windows.
474    
475            * Thuban/UI/mainwindow.py: Use True instead of true.
476    
477            * setup.py: Update some definitions to use wxWindows2.4 files
478    
479            * Data/iceland_sample_class.thuban: Fixed file so that the
480            field_type information is present.
481    
482    2003-03-10  Jonathan Coles   <[email protected]>
483    
484            * Thuban/UI/classifier.py (Classifier.__init__): Make the
485            field type label grow so that when the text changes the
486            size is updated correctly. This may be a wxWindows bug.
487    
488    2003-03-10  Jonathan Coles   <[email protected]>
489    
490            * Thuban/UI/application.py: Changed SESSION_CHANGED to
491            SESSION_REPLACED.
492    
493            * Thuban/UI/classifier.py: Wrap text with _().
494            (ClassGrid.CreateTable): Set dimensions and size hints here,
495            instead of in Reset, so we only set the size once.
496    
497            * Thuban/UI/dialogs.py: Don't need Shutdown(); just use Close()!
498    
499            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
500            Call Close() instead of Shutdown().
501    
502            * Thuban/UI/messages.py: Changed SESSION_CHANGED to SESSION_REPLACED.
503    
504            * Thuban/UI/tree.py: Changed SESSION_CHANGED to SESSION_REPLACED.
505            Go back to using OnClose() instead of Shutdown().
506    
507    2003-03-10  Jonathan Coles   <[email protected]>
508    
509            * Thuban/UI/classifier.py (Classifier): SelectField() needed
510            to know the old field index as well as the new one.
511    
512    2003-03-10  Jonathan Coles   <[email protected]>
513    
514            * Thuban/UI/classifier.py (Classifier): Use __SelectField()
515            to correctly set the table information and call this from
516            __init__ and from _OnFieldSelect so that all the information
517            is up to date when the dialog opens and when a field is changed.
518    
519    2003-03-10  Jonathan Coles   <[email protected]>
520    
521            * Thuban/Model/classification.py (Classification): Don't use
522            layer's message function directly, use the ClassChanged() method
523            when then classification changes. SetField/SetFieldType/SetLayer
524            must keep the information about field name and field type in
525            sync when an owning layer is set or removed.
526    
527            * Thuban/Model/layer.py: Added ClassChanged() so that the
528            classification can tell the layer when its data has changed.
529            (Layer.SetClassification): Accepts None as an arguement to
530            remove the current classification and correctly handles
531            adding a new classification.
532    
533            * Thuban/Model/load.py: Comment out print statement
534    
535            * test/test_classification.py, test/test_save.py: New and
536            improved tests.
537    
538    2003-03-07  Jonathan Coles   <[email protected]>
539    
540            * Thuban/Model/classification.py: Implemented __copy__ and
541            __deepcopy__ for ClassGroup* and ClassGroupProperites so
542            they can easily be copied by the classifier dialog.
543            (ClassGroupProperites.__init__): The default line color should
544            have been Color.Black.
545    
546            * Thuban/UI/classifier.py: Setting and Getting table values now
547            uses a consistent set of functions.
548            (Classifier): Now non-modal. Has field type label which changes
549            as the field changes. Keep track of buttons in a list so that
550            we can enable/disable the buttons when the None field is selected.
551            (SelectPropertiesDialog): Add buttons to make the colors transparent.
552    
553            * Thuban/UI/dialogs.py (NonModalDialog.Shutdown): New method which
554            does what OnClose did, but can be called by the application to
555            close a window. Needed when a session changes, and we have to
556            close the classifier windows.
557    
558            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
559            Shuts down open dialogs. Used when a new session is created
560            or a session is opened.
561            (MainWindow.SaveSession): Should only call application.SaveSession()
562            if we don't call SaveSessionAs first.
563            (MainWindow.Classify): Allow different classifier dialogs for
564            different layers.
565    
566            * Thuban/UI/tree.py (SessionTreeView): Remove OnClose and let
567            the parent class handle it. Add Shutdown() to unsubscibe from
568            event notification and call the parent Shutdown(). This was
569            necessary so the application can close the tree window.
570    
571    2003-03-06  Jonathan Coles   <[email protected]>
572    
573            * Thuban/Model/classification.py: Minor documentation changes,
574            Addition of __eq__ and __ne__ methods.
575            (Classification.SetLayer): prevent recursion between this method
576            and Layer.SetClassification().
577    
578            * Thuban/Model/color.py: Addition of __eq__ and __ne__ methods.
579    
580            * Thuban/Model/layer.py (SetClassification): prevent recursion
581            between this method and Classification.SetLayer().
582    
583            * test/test_classification.py, test/test_load.py,
584            test/test_session.py: Fixed and added tests for the classification
585            classes.
586    
587    2003-03-06  Bernhard Herzog  <[email protected]>
588    
589            * Thuban/UI/classifier.py (ClassGrid.__init__)
590            (ClassGrid.CreateTable): Move the SetSelectionMode call to
591            CreateTable because otherwise it triggers an assertion in
592            wxPython/wxGTK 2.4.
593    
594    2003-03-05  Jonathan Coles   <[email protected]>
595    
596            * Thuban/common.py: Move FIELDTYPE constants back to table.py.

605    
606            * Thuban/UI/classifier.py: Added class documentation.
607            Fixed RTbug #1713, #1714. Added Move[Up|Down] buttons.
608            Store just the groups in the table and generate the other
609            column information when it is requested. Add "None" field
610            to pull-down to select no classification.
611    
612            * Thuban/common.py: Moved FIELDTYPE constants from table.py
613            (Str2Num): Only catch ValueError exceptions.
614    
615            * Thuban/Model/classification.py: Class documentation. Renaming
616            of methods with Stroke to Line. Groups are stored in a single
617            list with the default as the first element. Groups are searched
618            in the order they appear in the list.
619    
620            * Thuban/Model/color.py: Documentation.
621    
622            * Thuban/Model/layer.py (Layer): Add GetFieldType to retreive
623            the kind of data represented by a field.
624    
625            * Thuban/Model/load.py (ProcessSession): Use proper string
626            conversion function; fixes RTbug #1713.

633    
634            * Thuban/UI/mainwindow.py: Function name changes.
635    
636            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
637            get the layer classification once. Don't try to classify
638            values when the field is None: just use the default properties.
639    
640            * Thuban/UI/view.py: Function name changes.
641    
642            * Doc/thuban.dtd: Add field_type attribute to a classification.
643    
644    2003-03-04  Bernhard Herzog  <[email protected]>
645    
646            * Doc/thuban.dtd: Use correct syntax for optional attributes. Make
647            the fill and stroke layer attributes optional with suitable
648            default values. Add the stroke_width layer attribute. Use correct
649            syntax for empty elements. Make the attribute list for labels
650            refer to the label element.
651    
652    2003-03-04  Bernhard Herzog  <[email protected]>
653    
654            * setup.py (thuban_build_py.build): Add a comment about distutils in
655            Python 2.3 containing some of the functionality we implement in
656            setup.py ourselves.
657    
658            * Thuban/UI/classifier.py (ClassGrid.__init__): Set the table
659            before the selection mode. Doing it the other way round triggers
660            an assertion in wxWindows.
661    
662            * Thuban/Model/save.py (escape): Fix typo in doc-string
663    
664            * Thuban/Model/classification.py: Remove unnecessary wxPython
665            import
666    
667    2003-03-04  Jonathan Coles   <[email protected]>
668    
669            * Thuban/Model/classification.py (ClassGroupRange.GetProperties):
670            Parameter 'value' should default to None.
671    
672            * Thuban/UI/mainwindow.py: Use Layer.GetClassification() since
673            the class attribute __classification is now private.
674    
675            * Thuban/UI/classifier.py (ClassGrid): Moved OnCellDClick() from
676            Classifier to ClassGrid. Added support for removing selected rows,
677            which including code for keeping track of when cells are selected,
678            and deselected.
679            (ClassTable): Support for added/removing rows. Fixed a problem
680            with __ParseInput whereby it would not allow strings (only numbers)
681            to be entered.
682            (Classifier): Added button and supporting code for removing
683            selected rows.
684    
685    2003-02-27  Jonathan Coles   <[email protected]>
686    
687            * Thuban/common.py: Moved color conversion functions into
688            Thuban/UI/common.py.
689            (Str2Num): Now converts the float (not the string) to a long/int
690            so that an exception isn't thrown.
691    
692            * Thuban/UI/common.py: Common functions used in several UI modules
693    
694            * Thuban/Model/classification.py: Changed the class hierarchy
695            so that a Classification consists of Groups which return
696            Properties when a value matches a Group.
697    
698            * Thuban/Model/layer.py: Fixed name resolution problem.
699    
700            * Thuban/Model/load.py: Use new Classification and Group functions.
701    
702            * Thuban/Model/save.py (Saver.write_attribs): Fixes a test case
703            failure.
704            (Saver.write_classification): Use new Classification and Group
705            functions.
706    
707            * Thuban/UI/classifier.py: Changes to use new Classification and Group
708            functions. Fix to create a tuple with a single value instead of
709            simply returning the value.
710    
711            * Thuban/UI/renderer.py: Use new Classification and Group functions.
712            Use common.py functions.
713    
714            * Thuban/UI/tree.py: Use common.py functions.
715            
716            * test/test_classification.py: Use new Classification and Group
717            classes.

731            the new iterator to save the classification information.
732    
733            * Thuban/UI/classifier.py (SelectPropertiesDialog): Support
734            for changing the stroke and fill colors and previewing the

736    
737            * Thuban/UI/mainwindow.py (MainWindow.OpenSession,
738            MainWindow.SaveSessionAs): Text string changes so the dialogs
739            have more meaningful titles.
740    
741            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Change
742            Classification method name from GetProperties to GetClassData.
743    
744            * Thuban/UI/view.py (MapCanvas.find_shape_at): Use method calls
745            instead of accessing now non-existent class variables.
746    
747    2003-02-24  Bernhard Herzog  <[email protected]>
748    
749            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Remove
750            unneeded Shape() call. Rendering is substantially faster without
751            it and it avoids some problems with broken shape files.
752    
753    2003-02-20  Frank Koormann   <[email protected]>
754    
755            Force minimal size of identify and label dialogs. The autosizing
756            looked too ugly.

767            test/test_load.py, test/test_map.py, test/test_session.py:
768            Updated the tests to use the new functions that are in the
769            respective classes.
770    
771            * Thuban/Model/classification.py (Classification):
772            Uses the new ClassData* classes. Modification messages are
773            passed up to the parent layer (if it exists).

784            with no color.
785    
786            * Thuban/Model/layer.py (Layer): Removed references to fill, stroke,
787            stroke_width attributes. Made the 'classification' attribute private.
788            New methods for setting/getting the classification.
789    
790            * Thuban/Model/load.py (ProcessSession): Use new methods on Layer
791            to get the classifcation and use the new ClassData* classes to
792            hold the classification data. Use Str2Num to convert numbers
793            properly.
794    
795            * Thuban/Model/save.py (Saver): Use new Color and Classification
796            methods
797    
798            * Thuban/UI/classifier.py (ClassGrid): New class to represent a
799            custom grid.

1194            (_tool_command): Put the code that generates the "checked"
1195            callback into a separate function so that we can reuse it
1196            elsewhere
1197    
1198            * Thuban/Model/save.py (Saver): New class to handle serializing a
1199            session into an XML file. The main reason to introduce a class is
1200            that applications built on Thuban can derive from it so that they
1201            can save additional information in a session file.
1202            (save_session): Delegate almost all the work to the Saver class.
1203            Rename the filename argument to file because it may be a file like
1204            object now.
1205    
1206            * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
1207            code. Remove the little test code which would be executed when the
1208            module is run as a script which didn't work anymore since it can't
1209            import the other Thuban modules.
1210            (ProcessSession, load_session): Refactor the ProcessSession to
1211            have one method for each element start and end tag so that derived
1212            classes can easily override the processing of individual tags.
1213            Also, always parse with namespaces enabled because applications
1214            built on top of Thuban will likely use namespaces if they extend
1215            the session file format.
1216    
1217    2002-08-21  Bernhard Herzog  <[email protected]>
1218    
1219            * setup.py (ThubanInstall.run): Don't repr install_lib_orig
