94            a test for the new exception in DerivedShapeStore.__init__.
95    
96            * test/support.py (FloatTestCase): Removed since there is
97            already FloatComparisonMixin. Fixes RTbug #1954.
98            (FloatComparisonMixin.assertFloatEqual): Include test for
99            infinity that was part of FloatTestCase.
100    
101            * test/test_range.py (RangeTest): Inherit from
102            support.FloatComparisonMixin now that we don't have
103            support.FloatTestCase.
104    
105    2003-06-20  Bernhard Herzog  <[email protected]>
106    
107            * test/test_save.py (SaxEventLister, sax_eventlist): Removed. Use

115    
116            * test/test_load.py (LoadSessionTest.check_format): New helper

119            (ClassificationTest.TestLayers, TestSingleLayer.test)
120            (TestLayerVisibility.test, TestClassification.test)
121            (TestLabels.test, TestLayerProjection.test, TestRasterLayer.test):
122            Add check_format() calls and fix the thuban data to match the data
123            that would be written by saving the session loaded from it.
124    
125            * test/xmlsupport.py (SaxEventLister, sax_eventlist): Copies of

133            * Resources/XML/thuban.dtd: Add comment about which versions of
134            Thuban are covered by this DTD
135            (map): Fix content model for layers and raster layers. There can
136            be any number or layers and raster layers in any order.
137    
138    2003-06-20  Jonathan Coles   <[email protected]>
139    
140            This is mainly about fixing RTbug #1949.
141    
142            * Thuban/Model/classification.py: Remove "from __future__"
143            import statement since python 2.2 is the earliest supported
144            version.
145    
146            * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
147            Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES
148            depending on the units this projection *forwards* into.
149    
150            * Thuban/Model/save.py (SessionSaver.write_classification):
151            Remove unnecessary use of lambdas and nested functions.
152    
153            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Do scale
154            adjustment here if the map projection uses degrees.
155    
156            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
157            scale adjust code since it is now done before calling
158            this method. Don't do anything if the map projection
159            is None.
160    
161    2003-06-19  Bernhard Herzog  <[email protected]>
162    
163            Move version specific load tests to their own file.
164    
165            * test/test_load.py: Expand the doc-string to explain a bit how to
166            handle file format changes.
167            (TestClassification.test): Update the docstring as this test is
168            not about Thuban 0.2 anymore.
169    
170            * test/test_load_0_2.py: New file with the load tests for thuban
171            files created with Thuban 0.2 and earlier.
172    
173    2003-06-19  Bernhard Herzog  <[email protected]>
174    
175            Add XML validation to some of the tests. Validation will only be
176            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
177            To make the DTD available to the test cases it's moved into
178            Resources/XML
179    
180            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
181            for versions up to and including 0.2. Two slight changes: added an
182            encoding specification and fixed the comment which refered to
183            GRASS, not Thuban
184    
185            * test/xmlsupport.py: New support module for tests involving XML.
186            Currently there's a mix-in class for XML validation.
187    
188            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
189    
190            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
191            so that we can validate the
192            (SaveSessionTest.testEmptySession)
193            (SaveSessionTest.testSingleLayer)
194            (SaveSessionTest.testSingleLayer)
195            (SaveSessionTest.testLayerProjection)
196            (SaveSessionTest.testRasterLayer)
197            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
198    
199            * test/runtests.py (main): Call print_additional_summary instead
200            of print_garbage_information
201    
202            * test/support.py (resource_dir): New function to return the
203            "Resource" subdirectory
204            (print_additional_summary): New function to combine several
205            summary functions
206            (run_tests): Use print_additional_summary instead of calling
207            print_garbage_information directly
208    
209    2003-06-19  Bernhard Herzog  <[email protected]>
210    
211            * Doc/thuban.dtd (classification): Correct the content model of
212            the classification element.
213            (projection): Add the "name" attribute
214    
215    2003-06-19  Frank Koormann   <[email protected]>
216    
217            MERGE from the greater-ms3 branch.
218    
219            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
220            scale if projection is latlong to get better estimate.
221    
222            Fix problem of hidden properties dialog under windows after double
223            click on layer tree:
224            The tree control always gets an Expanded / Collapsed event after
225            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
226            raises the already displayed window.
227    
228            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
229            raiseProperties initialized to prevent endless loops
230            (LegendTree._OnItemActivated): Depending on self.raiseProperties
231            simply raise the properties or open the dialog and issue a second
232            event.
233    
234    2003-06-18  Jonathan Coles   <[email protected]>
235    
236            * setup.py: Fix a few problems that occured under Windows.
237    
238    2003-06-18  Jonathan Coles   <[email protected]>
239    
240            When Thuban loaded the map was redrawn twice because the
241            legend was being opened after the mainwindow was created
242            and not during its creation. This meant the map was drawn
243            initially and then had to be redrawn when the legend
244            caused the display to change. Now the legend is opened
245            in the mainwindow constructor which resolves this issue.
246    
247            Also, although we were checking for the existence of
248            gdal and gdalwarp modules, the gdalwarp extension was
249            still being compiled (which may fail if the system doesn't
250            have gdal installed). the build_ext command to setup.py
251            now accepts the flags --with-gdal and --without-gdal.
252            If --without-gdal is specified setup.py will try to
253            use the gdal parameters specified by gdal-config. Under
254            windows, those parameters have to be set in setup.py
255            as with proj4 an wxWindows.
256    
257            * setup.py: Use a list instead of seperate variables for
258            extension parameters so we can create a generic function
259            that runs an appropriate *-config script.
260            (run_cs_script): Renamed from run_wx_script and modified
261            to accept a second argument which is a list of lists to
262            be filled in by the values returned from running the command.
263            (thuban_build_ext): New. Extends the build_ext command and
264            provides the options --with-gdal/--without-gdal which then
265            optionally includes the gdalwarp extension.
266    
267            * Thuban/Model/resource.py: First check if we can import
268            the gdalwarp Thuban extension before checking for gdal.
269            Also added some comments.
270            
271            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
272            the map is None which may be the case if none has been loaded
273            yet.
274    
275            * Thuban/UI/main.py (main): Remove call to ShowLegend.
276    
277            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
278    
279            * Thuban/UI/renderer.py: Check for gdal support before importing
280            gdalwarp.
281            (MapRenderer.render_map): Only try to optimize if we have gdal
282            support otherwise nothing will get drawn.
283    
284            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
285            during startup before a map has been created. Check if map is None
286            before using it and do nothing if it is.
287    
288    2003-06-17  Jonathan Coles   <[email protected]>
289    
290            Fix the problem with raster layers under Windows that caused
291            Thuban to crash. The view should respond to layer projection
292            changed events to update the display. Changes to a projection
293            should not cause the map to be set to full extent.
294            
295            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
296            current_map_proj to remember the current map projection so that
297            when the projection changes we know what the previous projection
298            was.
299            (MapCanvas.SetMap): Unsubscribe and subscribe to
300            LAYER_PROJECTION_CHANGED events.
301            (MapCanvas.projection_changed): Split into two methods that respond
302            to map and layer projection changes.
303            (MapCanvas.map_projection_changed): New. Takes the current view and
304            projects it using the new projection. This does not cause the
305            map to be redrawn at full extent.
306            (MapCanvas.layer_projection_changed): New. Cause a redraw which
307            will draw each layer in its new projection.
308            
309            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
310            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
311            under Windows.
312            
313            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
314            to twice sizeof(void*) because there are two digits for each
315            hex byte.
316    
317    2003-06-16  Bernhard Herzog  <[email protected]>
318    
319            Update to the layer interface: Direct access to the table,
320            shapetable, shapefile and filename attributes is now actively
321            deprecated by issuing deprecation warnings for all places where
322            this happens.
323    
324            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
325            to the instance variables table, shapetable, shapefile and
326            filename via __getattr__ so that we can issue a deprecation
327            warning.
328            (Layer.SetShapeStore): Don't set the deprecated instance variables
329            any more
330            (Layer.SetShapeStore): Don't use deprecated layer instance
331            variables
332            (Layer.Destroy): No need to explicitly remove the instance
333            variables any more
334            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
335            instance variables
336    
337            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
338            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
339            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
340            use deprecated layer instance variables
341    
342            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
343            deprecated layer instance variables
344    
345            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
346            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
347            instance variables
348    
349            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
350            deprecated layer instance variables
351    
352            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
353            deprecated layer instance variables
354    
355            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
356            deprecated layer instance variables
357    
358            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
359            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
360            variables
361    
362            * test/runtests.py (main): Turn Thuban's deprecation warnings into
363            errors so that they're cought by the tests
364    
365            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
366            layer instance variables
367    
368    2003-06-16  Jonathan Coles   <[email protected]>
369    
370            Fix a problem under Windows whereby if the user double-clicks on a
371            layer in the legend that tree item will expand or collapse as well
372            as open the layer properties dialog. The state of the tree item
373            should not be affected.
374    
375            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
376            preventExpandCollapse and subscribe to expanding and collapsing
377            events.
378            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
379            collapsing events and will veto the event if it has been triggered
380            by the user double clicking on a layer.
381            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
382            that an expanding/collapsing event should be vetoed.
383    
384    2003-06-13  Bernhard Herzog  <[email protected]>
385    
386            * Thuban/UI/classifier.py (Classifier.OnClose)
387            (Classifier.map_layers_removed)
388            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
389            in OnClose and not in map_layers_removed or
390            layer_shapestore_replaced to make sure it always happens when the
391            dialog is closed
392    
393    2003-06-13  Jonathan Coles   <[email protected]>
394    
395            This puts back a fix for Windows where a panel is needed so that
396            the background of the table view appears correctly.
397    
398            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
399            object that can be used by derived classes to place any
400            controls (including the grid) onto.
401            (QueryTableFrame.__init__): Use the panel as the parent window
402            for all the controls. Reparent the grid so that the panel is
403            the parent. Call UpdateStatusText() to correctly initialize
404            the status bar.
405    
406    2003-06-13  Jonathan Coles   <[email protected]>
407    
408            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
409            from wxFrame (as opposed to wxDialog like the other classes)
410            but otherwise behaves like the other classes. This is needed
411            for the TableView which isn't really a dialog and needs to
412            have a status bar and control buttons.
413    
414            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
415            instance variable to keep track of how many rows are selected.
416            Subscribe once to the the events we are interested in.
417            (ThubanGrid.OnRangeSelect): Only handle event if event handling
418            hasn't been turned off.
419            (ThubanGrid.OnSelectCell): Only handle event if event handling
420            hasn't been turned off.
421            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
422            as an event listener (which changes the event handler stack)
423            simply set an instance variable to False. This is checked in
424            the event handlers.
425            (ThubanGrid.GetNumberSelected): Return the number of currently
426            selected rows.
427            (TableFrame): Inherit from ThubanFrame so we can have a
428            status bar and control buttons.
429            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
430            Explicitly set which items are selected in the operator choice and
431            action choice so there is always a valid selection. Fixes RTbug #1941.
432            Subscribe to grid cell selection events so we can update the
433            status bar.
434            (QueryTableFrame.UpdateStatusText): Update the status bar with
435            how many rows are in the grid, how many columns, and how many
436            rows are selected.
437            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
438            Call UpdateStatusText when cells are (de)selected.
439            (QueryTableFrame.OnQuery): Use the string value in the value
440            combo if either the selected item index is 0 or if the string
441            cannot be found in the predefined list (this happens if the
442            user changes the text). Fixes RTbug #1940.
443            Only turn off the grid event listeners if there a query comes
444            back with a none empty list of ids. in the case that the list
445            is empty this causes a grid.ClearSelection() call to actually
446            clear the grid selection which causes the selected items in
447            the map to be deselected. Fixes RTbug #1939.
448    
449            * test/test_save.py (XMLWriterTest.Encode): Check return values.
450            Fixes RTbug #1851.
451    
452    2003-06-13  Bernhard Herzog  <[email protected]>
453    
454            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
455            self.selected_shape with the current selection to make sure the
456            contents of the dialog are up to date when it's shown for the
457            first time.
458            The dialog used to work without this by luck. The recent fix to
459            the connector module 'broke' a 'feature' the identify view was
460            relying on, i.e that subscribing to a message in response to
461            receiving a message of that type would mean that the new
462            subscriber would also be called for the same message.
463            
464    2003-06-12  Jonathan Coles   <[email protected]>
465    
466            * extensions/thuban/gdalwarp.cpp: Removed debug printing as
467            the image is rendered. Fixes RTbug #1937.
468    
469    2003-06-12  Jonathan Coles   <[email protected]>
470    
471            * Thuban/Lib/fileutil.py: As is done under Windows, create the
472            user directory if it doesn't exist on a posix system.
473            Fixes RTbug #1815.
474    
475            * Thuban/Model/resource.py (get_user_proj_files): Moved the
476            called to get_application_dir here, so that the directory
477            will only be called if this method is invoked.
478    
479            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
480            the projfilepath if no projection is selected.
481    
482    2003-06-12  Jonathan Coles   <[email protected]>
483    
484            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
485            the scalebar if the current map has no projection set.
486    
487            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
488            projfilepath label to just the basename of the projection file
489            rather than include the entire path.
490    
491            * Thuban/Model/resource.py: Fix missed proj functions that
492            needed to be renamed.
493    
494    2003-06-12  Jonathan Coles   <[email protected]>
495    
496            * Thuban/Model/classification.py: Removed assert statements that
497            tested if the variable was an instance of Color.
498    
499            * Thuban/Model/color.py (Color): Remove commented code that isn't
500            used.
501            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
502            Fixes RTbug #1835.
503            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
504            Needed now that the class doesn't inherit from Color.
505    
506    2003-06-12  Jonathan Coles   <[email protected]>
507    
508            * test/test_save.py (XMLWriterTest.testEncode): Explicitly
509            check unicode strings.
510    
511            * test/test_layer.py: Check for existence of gdal.
512    
513    2003-06-12  Jonathan Coles   <[email protected]>
514        
515            * Thuban/Model/xmlreader.py: New. Contains the XMLReader class
516            that was in load.py
517    
518            * Thuban/Model/xmlwriter.py: New. Contains the XMLWriter class
519            that was in save.py
520    
521    2003-06-12  Jonathan Coles   <[email protected]>
522    
523            This is largely a collection of bug fixes. We also handle the
524            case where gdal is not on the system. The XMLReader and XMLWriter
525            classes were moved into there own files to resolve some circular
526            import references and because they shouldn't really be in the
527            file that is dediciated to reading/writing session files since
528            they are also used elsewhere.
529    
530            * Thuban/Model/classgen.py: Renamed functions to follow the
531            function_names_with_underscores style. Fixes RTbug #1903.
532            (calculate_quantiles): Raise ValueError if 'percents' is invalid.
533    
534            * Thuban/Model/layer.py: Import gdal only if it available.

576    
577            * Thuban/UI/mainwindow.py (_has_gdal_support): New. Used to

580    
581            * Thuban/UI/projdialog.py: Use renamed projection resource functions.
582

634    
635            * Thuban/Lib/connector.py (Connector.Issue): Iterate over a copy
636            of the receivers list so that unsubscribing in a receiver doesn't

652    
653            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
654            parameter so we can subscribe to some of its messages
655            (Classifier.__init__): Subscribe to the map's MAP_LAYERS_REMOVED
656            and the layer's LAYER_SHAPESTORE_REPLACED

693    
694            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice

697            (ProjFrame.__FillAvailList): selectProj as second optional parameter,
698            if set, select the projection found under the specified name. This
699            overwrites any other selection estimate.

710            * Thuban/UI/identifyview.py (IdentifyView.__init__):
711            Use ListCtrl instead of GridCtrl
712    
713            * Thuban/Model/resource.py:
714            Guess location of .thuban directory from tempdir parent directory.
715    
716            * Thuban/UI/application.py (ThubanApplication.read_startup_files):

720    
721            Do not cache the values returned by the tree widget's
722            GetFirstChild and GetNextChild methods because it led to lots of
723            segfaults. The new way requires more brute force but is more
724            reliable.
725    
726            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
727            variable layer2id

730            (LegendTree._OnMsgLayerChanged)
731            (LegendTree._OnMsgLayerTitleChanged, LegendTree.__ShowHideLayer):
732            Use find_layer instead of layer2id
733            (LegendTree.__RemoveLayer, LegendTree.__AddLayer): No need to
734            update layer2id anymore
735            (LegendTree._OnMsgMapLayersRemoved)
736            (LegendTree._OnMsgMapLayersAdded): Get by without layer2id.

756            whether the modified flag is set properly
757    
758            * Thuban/Model/base.py (TitledObject.SetTitle): Call changed
759            instead of issue so that the modified flags get updated.
760    
761            * test/test_base.py (SomeTitledObject): Derive from Modifiable
762            instead of Publisher to reflect reality better and to accomodate
763            the fact that SetTitle now calls changed instead of issue
764    
765    2003-06-02  Bernhard Herzog  <[email protected]>
766    
767            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource
768            acquisition has to happen before the try in a try-finally.
769    
770    2003-06-02  Bernhard Herzog  <[email protected]>
771    
772            * Thuban/UI/legend.py (LegendTree._OnMsgMapLayersRemoved): It's
773            possible that a layer is removed that is not currently selected in
774            the legend so don't check for this.
775    
776    2003-05-30  Bernhard Herzog  <[email protected]>
777    
778            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
779            variables to None that have direct or indirect references to
780            shapefiles or dbf files to make sure that they do go away and the
781            files are closed.

856            to be compiled as a standalone app. Now the code can only be
857            called from Python which simplifies the parameter passing.
858            (ProjectRasterFile): Handle Python arguments. Remove code that
859            checks for a destination dataset. Add more clean up code.
860    
861            * test/test_map.py (TestMapWithContents.test_raise_layer_top,

1168            and call its init-method with a default title. Remove Title() method.
1169    
1170            * Thuban/Model/transientdb.py (TransientTable, TransientJoinedTable,
1171            AutoTransientTable): mix-in TitledObject and call its init-method with
1172            a default title. Remove Title() method.
1173    
1174    2003-05-23  Bernhard Herzog  <[email protected]>
1175    
1176            * Thuban/Model/session.py (Session.AddShapeStore): Define
1177            AddShapeStore analogously to AddTable.
1178    
1179            * test/test_session.py (TestSessionSimple.test_add_shapestore):
1180            New. Test for AddShapeStore
1181    
1182    2003-05-23  Jan-Oliver Wagner <[email protected]>
1183    
1184            Introducing QueryTableFrame and a very coarse ShowTable implementation.
1185    
1186            * Thuban/UI/tableview.py (LayerTableFrame, QueryTableFrame): Split the
1187            class LayerTableFrame into two classes, LayerTableFrame and QueryTableFrame.
1188            The latter implements the selection GUI without dependency on a layer.
1189            LayerTableFrame now is derived from QueryTableFrame and connects
1190            to a layer.
1191    
1192            * Thuban/UI/mainwindow.py (MainWindow.TableShow): A very coarse
1193            implementation that still needs work.
1194    
1195            * Thuban/Model/layer.py (Layer.TreeInfo): Added filename.
1196    
1197    2003-05-22  Frank Koormann  <[email protected]>
1198    
1199            * Thuban/Model/transientdb.py (TransientJoinedTable.__init__):
1200            Added "outer_join = False" as optional parameter.
1201            (TransientJoinedTable.create): If outer join is true, perform a
1202            "LEFT OUTER JOIN" instead of "JOIN", which preserves all records of
1203            the left table. Records not matching are filled with 0 / None.
1204    
1205            * Thuban/UI/join.py (JoinDialog.__init__): Checkbox for outer join.
1206            (JoinDialog.OnJoin): Consider outer join check box.
1207    
1208    2003-05-22  Bernhard Herzog  <[email protected]>
1209    
1210            * Thuban/UI/join.py (JoinDialog.OnJoin): Use exc_info in a
1211            somewhat safer way. Storing the traceback in a local variable can
1212            lead to memory leaks
1213    
1214    2003-05-22  Bernhard Herzog  <[email protected]>
1215    
1216            * Thuban/UI/join.py (JoinDialog.OnJoin): Make sure to really call
1217            the wxMessageDialog's Destroy() method.
1218    
1219    2003-05-22  Frank Koormann  <[email protected]>
1220    
1221            * Thuban/UI/join.py (JoinDialog.__init__): Make use of
1222            TransientTable.Title()
1223    
1224    2003-05-22  Frank Koormann  <[email protected]>
1225    
1226            Join Dialog, initial version.
1227    
1228            * Thuban/UI/mainwindow.py (MainWindow.TableJoin): Removed print.
1229    
1230            * Thuban/UI/join.py (JoinDialog): Functional implementation of
1231            former framework. Renamed Table1/Table2 to LeftTable/RightTable
1232            in all occurences.
1233    
1234            * Thuban/Model/transientdb.py (TransientJoinedTable.__doc__):
1235            Typo fixed.
1236    
1237    2003-05-22  Bernhard Herzog  <[email protected]>
1238    
1239            Give the tables titles so that the GUI can display more meaningful
1240            names. For now the titles are fixed but depend on e.g. filenames
1241            or the titles of the joined tables.
1242    
1243            * Thuban/Model/transientdb.py (TransientTable.Title)
1244            (TransientJoinedTable.Title, AutoTransientTable.Title): New.
1245    
1246            * Thuban/Model/table.py (DBFTable.Title, MemoryTable.Title): New.
1247    
1248            * test/test_transientdb.py
1249            (TestTransientTable.test_auto_transient_table_title): New. Test
1250            for the Title method
1251            (TestTransientTable.test_transient_joined_table)
1252            (TestTransientTable.test_transient_table): Add test for the Title
1253            methods
1254    
1255            * test/test_memory_table.py (TestMemoryTable.test_title): New.
1256            Test for the Title method
1257    
1258            * test/test_dbf_table.py (TestDBFTable.test_title): New. Test for
1259            the Title method
1260    
1261    2003-05-22  Bernhard Herzog  <[email protected]>
1262    
1263            * test/test_layer.py (TestLayer.setUp, TestLayer.tearDown):
1264            Provide a better way to destroy the layers
1265            (TestLayer.test_base_layer, TestLayer.test_arc_layer)

1272            * Thuban/Model/layer.py (Layer.SetShapeStore): Only set the
1273            filename if the shape store actually has one.
1274    
1275    2003-05-22  Bernhard Herzog  <[email protected]>
1276    
1277            * Thuban/Model/table.py (DBFTable.FileName): New. Accessor method
1278            for the filename
1279    
1280            * test/test_dbf_table.py (TestDBFTable.test_filename): New. Test
1281            for the FileName method
1282            (TestDBFTableWriting.test_write): Fix spelling of filename
1283    
1284    2003-05-22  Thomas Koester  <[email protected]>
1285    
1286            * Thuban/Model/range.py, test/test_range.py: Brought over new Range
1287            from SciParam that now really is immutable.
1288    
1289    2003-05-22  Frank Koormann  <[email protected]>
1290    
1291            Layer Top/Bottom placement added to legend.
1292    
1293            * Thuban/UI/legend.py
1294            (LegendPanel._OnMoveTop(), LayerPanel._OnMoveBottom): New, methods
1295            bound to tool events.
1296            (LegendTree.MoveCurrentItemTop(), LegendTree.MoveCurrentItemBottom):
1297            New, methods binding the event methods with the map methods.
1298    
1299            * Thuban/Model/map.py (Map.TopLayer(), Map.BottomLayer()): New, place
1300            layer at top/bottom of layer stack.
1301    
1302            * Resources/Bitmaps/top_layer.xpm: New button icon.
1303    
1304            * Resources/Bitmaps/bottom_layer.xpm: New button icon.
1305    
1306    2003-05-22  Bernhard Herzog  <[email protected]>
1307    
1308            * Thuban/Model/session.py (Session.RemoveTable): New method to
1309            remove tables
1310    
1311            * test/test_session.py (TestSessionSimple.test_remove_table): New.
1312            Test for RemoveTable
1313    
1314    2003-05-22  Thomas Koester  <[email protected]>
1315    
1316            * Thuban/Model/classgen.py: Added short module doc string and CVS id.
1317            (ClassGenerator.GenUniformDistribution): Use new Range __init__, too.
1318    
1319    2003-05-22  Bernhard Herzog  <[email protected]>
1320    
1321            Implement a way to discover dependencies between tables and
1322            shapestores.
1323    
1324            * Thuban/Model/transientdb.py (TransientTableBase.Dependencies)
1325            (TransientJoinedTable.Dependencies)
1326            (AutoTransientTable.SimpleQuery): New. Implement the dependencies
1327            interface
1328            (TransientJoinedTable.__init__): Keep tack of the original table
1329            objects in addition to the corresponding transient tables.
1330    
1331            * Thuban/Model/table.py (DBFTable.Dependencies)
1332            (MemoryTable.Dependencies): New. Implement the dependencies
1333            interface
1334    
1335            * Thuban/Model/data.py (ShapeTable): New. Helper class for
1336            ShapefileStore
1337            (ShapefileStore.__init__): Use ShapeTable instead of
1338            AutoTransientTable
1339            (ShapefileStore.Table, ShapefileStore.Shapefile): Add doc-strings
1340            (ShapefileStore.FileName, ShapefileStore.FileType): New. Accessor
1341            methods for filename and type
1342            (ShapefileStore.Dependencies): New. Implement the dependencies
1343            interface
1344            (DerivedShapeStore): New class to replace SimpleStore. The main
1345            difference to SimpleStore is that it depends not on a shapefile
1346            but another shapestore which expresses the dependencies a bit
1347            better
1348            (SimpleStore.__init__): Add deprecation warning.
1349    
1350            * test/test_dbf_table.py (TestDBFTable.test_dependencies): New.

1355    
1356            * test/test_transientdb.py
1357            (TestTransientTable.test_auto_transient_table_dependencies): New.
1358            Test for the Dependencies method.
1359            (TestTransientTable.test_transient_joined_table): Add test for the
1360            Dependencies method.
1361    
1362            * test/test_session.py (TestSessionSimple.setUp)
1363            (TestSessionSimple.tearDown): New. Implement a better way to
1364            destroy the sessions.
1365            (TestSessionSimple.test_initial_state)
1366            (TestSessionSimple.test_add_table): Bind session to self.session
1367            so that it's destroyed by tearDown
1368            (TestSessionSimple.test_open_shapefile): New. Test for
1369            OpenShapefile and the object it returns
1370    
1371    2003-05-22  Bernhard Herzog  <[email protected]>
1372    
1373            * Thuban/Model/session.py (Session.AddTable): New method to
1374            register tables with the session.
1375            (Session.Tables): Return the tables registered with AddTable too.
1376    
1377            * test/test_session.py (TestSessionSimple.test_add_table): New.
1378            Test case for the AddTable method
1379    
1380    2003-05-22  Frank Koormann  <[email protected]>
1381    
1382            UI polishing updates: Place main buttons (OK, Cancel, etc) in the
1383            lower right corner, center labels for selections, initialize controls
1384            in reasonable order for keyboard navigation.
1385    
1386            * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
1387            (ProjFrame.__DoOnProjAvail): Determine position of current projection
1388            using the wxListBox.FindString() method. Still a problem (#1886)
1389    
1390            * Thuban/UI/classifier.py
1391            (Classifier.__init__, SelectPropertiesDialog.__init__)
1392    
1393            * Thuban/UI/classgen.py (ClassGenDialog.__init__,
1394            (ClassGenDialog.__DoOnGenTypeSelect): Moved initialization of the
1395            different classification types from here to __init__.
1396            (GenUniquePanel.__init__): Set the column width of the first field
1397            in the Field ListCtrl to the full width.
1398    
1399            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Rename 'Save As'
1400            Button to 'Export'. Center Buttons in Selection Box, set Focus to
1401            Grid.
1402            (LayerTableFrame.OnKeyDown()): New, bound to the grid with EVT_KEY_DOWN,
1403            changes focus to the Selection when pressing "Alt-S".
1404    
1405            * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
1406            the text if not visible. The italic font sometimes exceeds the
1407            rendering area.
1408    
1409    2003-05-21  Jonathan Coles   <[email protected]>
1410    
1411            * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
1412            to OnClose so that Thuban closes correctly.
1413    
1414            * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
1415            DockFrame.OnClose, not DockFrame._OnClose.
1416    
1417    2003-05-21  Jonathan Coles   <[email protected]>
1418    
1419            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
1420            references to 'inf' and use new Range __init__ to pass floats
1421            directly rather than converting them to strings first.
1422            Fixes RTBug #1876.
1423    
1424            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
1425            Use new Range ___init__ to pass floats.
1426    
1427            * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
1428            filename is a valid image file. Throw IOError otherwise.
1429    
1430            * Thuban/Model/range.py: Brought over new Range from SciParam that
1431            is immutable and has an __init__ which can accept floats.
1432    
1433            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
1434            into try block. AddLayer doesn't throw any exceptions anymore.
1435            (MainWindow.AddRasterLayer): Move constructor of RasterLayer into
1436            try block.
1437    
1438            * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as
1439            the first item in choices. Fixes RTBug #1882.
1440    
1441            * Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale
1442            has gone to 0 which is a serious problem. abort.
1443            (MapRenderer.draw_raster_layer): Catch IOError seperately and
1444            print the error from GDAL.
1445    
1446            * Thuban/UI/tableview.py (TableGrid.__init__): Call
1447            ToggleEventListeners to turn on listening.
1448            (TableGrid.ToggleEventListeners): New. Turns event listening on
1449            and off so as to prevent excessive messages.
1450            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
1451            to suppress excessive messages when selecting many rows.
1452            Fixes RTBug #1880.
1453    
1454            * Thuban/UI/view.py: Added checks against if scale == 0. This
1455            is a serious problem that can occur when an image without
1456            geo data is loading and causes the map projection bounds to
1457            go to infinity. Right now, the solution is to simply try
1458            to recover.
1459    
1460            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
1461            to set the MFILEReceiver attributes even if the data is NULL.
1462    
1463            * extensions/thuban/gdalwarp.cpp: Improved the error handling
1464            and passed GDAL messages back up to the Python layer. Also
1465            tried to fix some memory leaks that were present in the original
1466            utility but didn't matter because the program aborted.
1467    
1468            * test/test_range.py: Copied over tests from SciParam. Removed
1469            tests against importing. Fixes RTBug #1867.
1470    
1471    2003-05-21  Bernhard Herzog  <[email protected]>
1472    
1473            * test/test_load.py: Remove unused imports and restructure the
1474            test code
1475            (LoadSessionTest): Split into one class for each test and turn
1476            LoadSessionTest itself into the base class for all such session
1477            tests.
1478            (ClassificationTest): New base class for load tests that test
1479            classifications
1480            (TestSingleLayer, TestLayerVisibility, TestClassification)
1481            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
1482            for the individual tests
1483    
1484            * test/support.py (FileLoadTestCase.filename): New base class for
1485            file loading tests
1486    
1487    2003-05-21  Jan-Oliver Wagner <[email protected]>
1488    
1489            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
1490            Mercator' to 'UTM Zone 32' as a more convenient example.
1491            Added 'Gauss Krueger Zone 6'.
1492    
1493            * Data/iceland_sample_raster.thuban: political polygon now
1494            filled transparent to have the raster image visible at once.
1495    
1496    2003-05-21  Frank Koormann  <[email protected]>
1497    
1498            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
1499            OnClose() to keep in sync with extensions. Internally Thuban
1500            still uses "underscored" names.
1501    
1502    2003-05-20  Jonathan Coles   <[email protected]>
1503    
1504            This puts back Raster layer support. These layers support projections
1505            through the GDAL library. Currently, the CVS version is being used.
1506            There are no Debian packages available although this may change soon.
1507            A GDAL driver was extended to support writing to memory rather to
1508            files.
1509    
1510            There is still some work that needs to be done, such as some error
1511            handling when loading invalid images or when there is a problem
1512            projecting the image. This putback simply checks in the majority
1513            of the work.
1514    
1515            * setup.py: Add gdalwarp library extension.
1516    
1517            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
1518            Defaults to False, but can be overridden by subclasses if they
1519            support classification.
1520            (RasterLayer): New. Defines a new layer that represents an
1521            image.
1522    
1523            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
1524            tag handler.
1525            (SessionLoader.start_layer): Encode the filename.
1526            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
1527            New. Supports reading a rasterlayer tag.
1528    
1529            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
1530    
1531            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
1532            get a string in Latin1. If we get such as string convert it to
1533            unicode first, otherwise leave if alone before encoding.
1534            (SessionSaver.write_layer): Add support for writing both Layers
1535            and RasterLayers.
1536    
1537            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
1538            The right argument may not be a string, it could also be a Column.
1539    
1540            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
1541            Make initial window size 600x400. Fixes RTBug #1872.
1542    
1543            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
1544            the dialog is constructed so that we can support layers that
1545            do not have classifications.
1546            (Classifier._OnTry): Only build a classification if the layer
