3            When Thuban loaded the map was redrawn twice because the
4            legend was being opened after the mainwindow was created
5            and not during its creation. This meant the map was drawn
6            initially and then had to be redrawn when the legend
7            caused the display to change. Now the legend is opened
8            in the mainwindow constructor which resolves this issue.
9    
10            Also, although we were checking for the existence of
11            gdal and gdalwarp modules, the gdalwarp extension was
12            still being compiled (which may fail if the system doesn't
13            have gdal installed). the build_ext command to setup.py
14            now accepts the flags --with-gdal and --without-gdal.
15            If --without-gdal is specified setup.py will try to
16            use the gdal parameters specified by gdal-config. Under
17            windows, those parameters have to be set in setup.py
18            as with proj4 an wxWindows.
19    
20            * setup.py: Use a list instead of seperate variables for
21            extension parameters so we can create a generic function
22            that runs an appropriate *-config script.
23            (run_cs_script): Renamed from run_wx_script and modified
24            to accept a second argument which is a list of lists to
25            be filled in by the values returned from running the command.
26            (thuban_build_ext): New. Extends the build_ext command and
27            provides the options --with-gdal/--without-gdal which then
28            optionally includes the gdalwarp extension.
29    
30            * Thuban/Model/resource.py: First check if we can import
31            the gdalwarp Thuban extension before checking for gdal.
32            Also added some comments.
33            
34            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
35            the map is None which may be the case if none has been loaded
36            yet.
37    
38            * Thuban/UI/main.py (main): Remove call to ShowLegend.
39    
40            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
41    
42            * Thuban/UI/renderer.py: Check for gdal support before importing
43            gdalwarp.
44            (MapRenderer.render_map): Only try to optimize if we have gdal
45            support otherwise nothing will get drawn.
46    
47            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
48            during startup before a map has been created. Check if map is None
49            before using it and do nothing if it is.
50    
51    2003-06-17  Jonathan Coles   <[email protected]>
52    
53            Fix the problem with raster layers under Windows that caused
54            Thuban to crash. The view should respond to layer projection
55            changed events to update the display. Changes to a projection
56            should not cause the map to be set to full extent.
57            
58            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
59            current_map_proj to remember the current map projection so that
60            when the projection changes we know what the previous projection
61            was.
62            (MapCanvas.SetMap): Unsubscribe and subscribe to
63            LAYER_PROJECTION_CHANGED events.
64            (MapCanvas.projection_changed): Split into two methods that respond
65            to map and layer projection changes.
66            (MapCanvas.map_projection_changed): New. Takes the current view and
67            projects it using the new projection. This does not cause the
68            map to be redrawn at full extent.
69            (MapCanvas.layer_projection_changed): New. Cause a redraw which
70            will draw each layer in its new projection.
71            
72            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
73            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
74            under Windows.
75            
76            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
77            to twice sizeof(void*) because there are two digits for each
78            hex byte.
79    
80    2003-06-16  Bernhard Herzog  <[email protected]>
81    
82            Update to the layer interface: Direct access to the table,
83            shapetable, shapefile and filename attributes is now actively
84            deprecated by issuing deprecation warnings for all places where
85            this happens.
86    
87            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
88            to the instance variables table, shapetable, shapefile and
89            filename via __getattr__ so that we can issue a deprecation
90            warning.
91            (Layer.SetShapeStore): Don't set the deprecated instance variables
92            any more
93            (Layer.SetShapeStore): Don't use deprecated layer instance
94            variables
95            (Layer.Destroy): No need to explicitly remove the instance
96            variables any more
97            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
98            instance variables
99    
100            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
101            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
102            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
103            use deprecated layer instance variables
104    
105            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
106            deprecated layer instance variables
107    
108            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
109            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
110            instance variables
111    
112            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
113            deprecated layer instance variables
114    
115            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
116            deprecated layer instance variables
117    
118            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
119            deprecated layer instance variables
120    
121            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
122            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
123            variables
124    
125            * test/runtests.py (main): Turn Thuban's deprecation warnings into
126            errors so that they're cought by the tests
127    
128            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
129            layer instance variables
130    
131    2003-06-16  Jonathan Coles   <[email protected]>
132    
133            Fix a problem under Windows whereby if the user double-clicks on a
134            layer in the legend that tree item will expand or collapse as well
135            as open the layer properties dialog. The state of the tree item
136            should not be affected.
137    
138            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
139            preventExpandCollapse and subscribe to expanding and collapsing
140            events.
141            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
142            collapsing events and will veto the event if it has been triggered
143            by the user double clicking on a layer.
144            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
145            that an expanding/collapsing event should be vetoed.
146    
147    2003-06-13  Bernhard Herzog  <[email protected]>
148    
149            * Thuban/UI/classifier.py (Classifier.OnClose)
150            (Classifier.map_layers_removed)
151            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
152            in OnClose and not in map_layers_removed or
153            layer_shapestore_replaced to make sure it always happens when the
154            dialog is closed
155    
156    2003-06-13  Jonathan Coles   <[email protected]>
157    
158            This puts back a fix for Windows where a panel is needed so that
159            the background of the table view appears correctly.
160    
161            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
162            object that can be used by derived classes to place any
163            controls (including the grid) onto.
164            (QueryTableFrame.__init__): Use the panel as the parent window
165            for all the controls. Reparent the grid so that the panel is
166            the parent. Call UpdateStatusText() to correctly initialize
167            the status bar.
168    
169    2003-06-13  Jonathan Coles   <[email protected]>
170    
171            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
172            from wxFrame (as opposed to wxDialog like the other classes)
173            but otherwise behaves like the other classes. This is needed
174            for the TableView which isn't really a dialog and needs to
175            have a status bar and control buttons.
176    
177            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
178            instance variable to keep track of how many rows are selected.
179            Subscribe once to the the events we are interested in.
180            (ThubanGrid.OnRangeSelect): Only handle event if event handling
181            hasn't been turned off.
182            (ThubanGrid.OnSelectCell): Only handle event if event handling
183            hasn't been turned off.
184            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
185            as an event listener (which changes the event handler stack)
186            simply set an instance variable to False. This is checked in
187            the event handlers.
188            (ThubanGrid.GetNumberSelected): Return the number of currently
189            selected rows.
190            (TableFrame): Inherit from ThubanFrame so we can have a
191            status bar and control buttons.
192            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
193            Explicitly set which items are selected in the operator choice and
194            action choice so there is always a valid selection. Fixes RTbug #1941.
195            Subscribe to grid cell selection events so we can update the
196            status bar.
197            (QueryTableFrame.UpdateStatusText): Update the status bar with
198            how many rows are in the grid, how many columns, and how many
199            rows are selected.
200            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
201            Call UpdateStatusText when cells are (de)selected.
202            (QueryTableFrame.OnQuery): Use the string value in the value
203            combo if either the selected item index is 0 or if the string
204            cannot be found in the predefined list (this happens if the
205            user changes the text). Fixes RTbug #1940.
206            Only turn off the grid event listeners if there a query comes
207            back with a none empty list of ids. in the case that the list
208            is empty this causes a grid.ClearSelection() call to actually
209            clear the grid selection which causes the selected items in
210            the map to be deselected. Fixes RTbug #1939.
211    
212            * test/test_save.py (XMLWriterTest.Encode): Check return values.
213            Fixes RTbug #1851.
214    
215    2003-06-13  Bernhard Herzog  <[email protected]>
216    
217            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
218            self.selected_shape with the current selection to make sure the
219            contents of the dialog are up to date when it's shown for the
220            first time.
221            The dialog used to work without this by luck. The recent fix to
222            the connector module 'broke' a 'feature' the identify view was
223            relying on, i.e that subscribing to a message in response to
224            receiving a message of that type would mean that the new
225            subscriber would also be called for the same message.
226            
227    2003-06-12  Jonathan Coles   <[email protected]>
228    
229            * extensions/thuban/gdalwarp.cpp: Removed debug printing as
230            the image is rendered. Fixes RTbug #1937.
231    
232    2003-06-12  Jonathan Coles   <[email protected]>
233    
234            * Thuban/Lib/fileutil.py: As is done under Windows, create the
235            user directory if it doesn't exist on a posix system.
236            Fixes RTbug #1815.
237    
238            * Thuban/Model/resource.py (get_user_proj_files): Moved the
239            called to get_application_dir here, so that the directory
240            will only be called if this method is invoked.
241    
242            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
243            the projfilepath if no projection is selected.
244    
245    2003-06-12  Jonathan Coles   <[email protected]>
246    
247            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
248            the scalebar if the current map has no projection set.
249    
250            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
251            projfilepath label to just the basename of the projection file
252            rather than include the entire path.
253    
254            * Thuban/Model/resource.py: Fix missed proj functions that
255            needed to be renamed.
256    
257    2003-06-12  Jonathan Coles   <[email protected]>
258    
259            * Thuban/Model/classification.py: Removed assert statements that
260            tested if the variable was an instance of Color.
261    
262            * Thuban/Model/color.py (Color): Remove commented code that isn't
263            used.
264            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
265            Fixes RTbug #1835.
266            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
267            Needed now that the class doesn't inherit from Color.
268    
269    2003-06-12  Jonathan Coles   <[email protected]>
270    
271            * test/test_save.py (XMLWriterTest.testEncode): Explicitly
272            check unicode strings.
273    
274            * test/test_layer.py: Check for existence of gdal.
275    
276    2003-06-12  Jonathan Coles   <[email protected]>
277        
278            * Thuban/Model/xmlreader.py: New. Contains the XMLReader class
279            that was in load.py
280    
281            * Thuban/Model/xmlwriter.py: New. Contains the XMLWriter class
282            that was in save.py
283    
284    2003-06-12  Jonathan Coles   <[email protected]>
285    
286            This is largely a collection of bug fixes. We also handle the
287            case where gdal is not on the system. The XMLReader and XMLWriter
288            classes were moved into there own files to resolve some circular
289            import references and because they shouldn't really be in the
290            file that is dediciated to reading/writing session files since
291            they are also used elsewhere.
292    
293            * Thuban/Model/classgen.py: Renamed functions to follow the
294            function_names_with_underscores style. Fixes RTbug #1903.
295            (calculate_quantiles): Raise ValueError if 'percents' is invalid.
296    
297            * Thuban/Model/layer.py: Import gdal only if it available.
298            (RasterLayer): Handle the case where the gdal library is unavailable.
299            Addresses RTbug #1877.
300    
301            * Thuban/Model/load.py (XMLReader): Moved into seperate file
302            xmlreader.py.

308            classes were moved into there own files to resolve some circular
309            import references and because they shouldn't really be in the
310            file that is dediciated to reading/writing session files since
311            they are also used elsewhere.
312

316    
317            * Thuban/Model/layer.py: Import gdal only if it available.
318            (RasterLayer): Handle the case where the gdal library is unavailable.
319            Addresses RTbug #1877.
320    
321            * Thuban/Model/load.py (XMLReader): Moved into seperate file
322            xmlreader.py.
323

325            file xmlwriter.py.
326    
327            * Thuban/Model/resource.py: Renamed functions to following the
328            function_names_with_underscores style.
329            (has_gdal_support): New function that returns true if the gdal
330            library is available. Addresses RTbug #1877.
331    
332            * Thuban/UI/application.py (ThubanApplication.OpenSession):
333            Display a message box if the gdal library is not available, but
334            only if there are any layers that would use it. Addresses RTbug #1877.
335    
336            * Thuban/UI/classgen.py: Use renamed projection resource functions.
337            (GenUniformPanel.__CalcStepping): Fix a slight discrepency
338            when using integers versus floats.
339    
340            * Thuban/UI/mainwindow.py (_has_gdal_support): New. Used to
341            determine if the "Add Image Layer" menu option should be
342            greyed out or not. Addresses RTbug #1877.
343    
344            * Thuban/UI/projdialog.py: Use renamed projection resource functions.
345    
346            * Thuban/UI/renderer.py (MapRenderer.render_map): Only try to
347            optimize if a raster layer is visible. Fixes RTbug #1931.
348            Only draw the raster layer if the gdal library is available.
349            Addresses RTbug #1877.
350    
351            * test/test_classgen.py: Add tests for generate_singletons,
352            generate_uniform_distribution, generate_quantiles. Fixes RTbug #1903.
353            (test_calculate_quantiles): Fix some tests to catch the new
354            ValueError that is raised.
355    
356            * test/test_proj.py: Use renamed projection resource functions.
357    
358            * test/test_save.py (SaveSessionTest.testClassifiedLayer): New
359            test for saving classified layers. Fixes RTbug #1902.
360            (XMLWriterTest): New. Tests the XMLWriter class. Fixes RTbug #1851.
361    
362    2003-06-12  Jan-Oliver Wagner <[email protected]>
363    
364            Fix for http://intevation.de/rt/webrt?serial_num=1900.
365    
366            * Thuban/UI/multiplechoicedialog.py: New. A multiple choice dialog.
367    
368            * Thuban/UI/mainwindow.py: import wxMultipleChoiceDialog from
369            multiplechoicedialog.py rather than from the wxPython library.
370    
371    2003-06-11  Frank Koormann  <[email protected]>

379            determine the absolute .thuban/thuban directory under
380            "posix" (os.expanduser) and "nt" (read AppData registry key).
381    
382            * Thuban/Model/resource.py: Use get_application_dir

411    
412            * Thuban/Model/layer.py (Layer.SetShapeStore): Send
413            LAYER_SHAPESTORE_REPLACED when the shapestore changes. A
414            LAYER_CHANGED will still be sent if the classification changes.
415    
416            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
417            parameter so we can subscribe to some of its messages
418            (Classifier.__init__): Subscribe to the map's MAP_LAYERS_REMOVED

453            in the dialog.
454    
455    2003-06-05  Frank Koormann  <[email protected]>
456    
457            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
458            once on initialisation (Former implementation resulted in multiple
459            entries for each projection).
460            (ProjFrame.__FillAvailList): selectProj as second optional parameter,
461            if set, select the projection found under the specified name. This
462            overwrites any other selection estimate.

472    
473            * Thuban/UI/identifyview.py (IdentifyView.__init__):
474            Use ListCtrl instead of GridCtrl

481    
482    2003-06-04  Bernhard Herzog  <[email protected]>
483    
484            Do not cache the values returned by the tree widget's
485            GetFirstChild and GetNextChild methods because it led to lots of
486            segfaults. The new way requires more brute force but is more
487            reliable.
488    
489            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
490            variable layer2id

495            Use find_layer instead of layer2id
496            (LegendTree.__RemoveLayer, LegendTree.__AddLayer): No need to
497            update layer2id anymore
498            (LegendTree._OnMsgMapLayersRemoved)
499            (LegendTree._OnMsgMapLayersAdded): Get by without layer2id.

523    
524            * test/test_base.py (SomeTitledObject): Derive from Modifiable
525            instead of Publisher to reflect reality better and to accomodate
526            the fact that SetTitle now calls changed instead of issue
527    
528    2003-06-02  Bernhard Herzog  <[email protected]>
529    
530            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource
531            acquisition has to happen before the try in a try-finally.
532    
533    2003-06-02  Bernhard Herzog  <[email protected]>
534    
535            * Thuban/UI/legend.py (LegendTree._OnMsgMapLayersRemoved): It's
536            possible that a layer is removed that is not currently selected in
537            the legend so don't check for this.
538    
539    2003-05-30  Bernhard Herzog  <[email protected]>
540    
541            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
542            variables to None that have direct or indirect references to

552    
553            * Thuban/UI/legend.py (LegendTree.__init__): New instance variable
554            changing_selection to indicate whether the LegendTree code itself
555            is currently changing the selection
556            (LegendTree.normalize_selection): New method to normalize the
557            selection by selecting the layer item even if the user clicked on
558            the classification.
559            (LegendTree._OnSelChanged): normalize the selection. This works
560            around a bug in wx which doesn't keep track of the selection
561            properly when subtrees are deleted.

581            of the ClassGenerator class. Put try/finally blocks around
582            code that uses wxBeginBusyCursor()/wxEndBusyCursor(). Fixes
583            RTBug #1904.
584    
585            * Thuban/UI/classifier.py: Remove unused import of ClassGenerator.
586    
587            * Thuban/UI/legend.py: The legend was cleared and repopulated any
588            time something changed which caused some state to be lost such
589            as which children were expanded or collapsed. Fixes RTBug #1901.
590            (LegendTree._OnMsgMapLayersAdded): Add only new layers.

599            and call __RemoveLayer.
600            (LegendTree.__AddLayer): New. Add a new layer to the legend.
601            (LegendTree.__RemoveLayer): Remove a layer from the legend.
602            (LegendTree.DeleteChildren): New, overrides wxTreeCtrl method.

617    
618            * extensions/thuban/gdalwarp.cpp: Removed code that allowed gdalwarp
619            to be compiled as a standalone app. Now the code can only be
620            called from Python which simplifies the parameter passing.
621            (ProjectRasterFile): Handle Python arguments. Remove code that
622            checks for a destination dataset. Add more clean up code.
623    
624            * test/test_map.py (TestMapWithContents.test_raise_layer_top,
625            TestMapWithContents.test_lower_layer_bottom):

845            anyway.
846            
847            * Thuban/Model/transientdb.py (TransientTableBase.Width):Use a
