# Line 1  Line 1 
1    2003-06-30  Jonathan Coles   <[email protected]>
2    
3            * Thuban/version.py: SQLite/PySQLite version dependencies
4            were too high.
5    
6    2003-06-30  Jonathan Coles   <[email protected]>
7    
8            * Thuban/version.py: Update version to 0.8.1
9            
10            * MANIFEST.in: Added Projections so that default.proj is
11            included.
12    
13    2003-06-26  Jonathan Coles   <[email protected]>
14    
15            New About box with lots more information including library
16            versions and credits. More/better version checking before
17            Thuban starts.
18    
19            * Thuban/UI/about.py: New. New About box that displays
20            library version information and credits.
21    
22            * Thuban/version.py: Added new 'versions' dictionary which
23            contains the verions of various libraries which are checked
24            when the module loads.
25            (verify_versions): Check all version numbers and returns
26            a list of errors.
27    
28            * Thuban/UI/classifier.py (Classifier.__EnableButtons):
29            Reset the status of the buttons as the situation warrants,
30            but in a better more reliable way by not relying on the
31            current status to determine what needs to change.
32    
33            * Thuban/UI/main.py (wxCHECK_VERSION): Removed. Not needed.
34            (verify_versions): Remove most of the code since it is
35            now in Thuban.version.verify_versions.o
36    
37            * Thuban/UI/mainwindow.py (MainWindow.About): Call new
38            About box in Thuban.UI.about.

48            was compiled with.
49    
50    2003-06-25  Jonathan Coles   <[email protected]>
51    
52            * Thuban/UI/classifier.py (Classifier.EditSymbol): The parent
53            of the SelectPropertiesDialog should be self so the window
54            appears on top.
55            (ClassGroupPropertiesCtrl.DoEdit): The parent
56            of the SelectPropertiesDialog should be self so the window
57            appears on top.
58    
59            * Thuban/UI/resource.py: Cleaned up how we determine file
60            extensions.
61            (GetImageResource): Return an wxImage from our Resources.
62    
63    2003-06-24  Jonathan Coles   <[email protected]>
64    
65            * Thuban/UI/renderer.py (ExportRenderer.render_legend):
66            Check that a layer has a classification before trying
67            to get it. Raster layers don't have classifications.

70            
71            * setup.py: Add Resources/XML to resource list.

76        
77    2003-06-23  Jonathan Coles   <[email protected]>
78    
79            * MANIFEST.in: Update with Resources/XML
80    
81            * setup.py: Don't include Locale resources yet as we don't
82            have any and it causes problems building the distribution
83            for Windows. Update version to 0.8.0.
84    
85            * Doc/thuban.dtd: Removed since it is now in Resources/XML.
86    
87            * Thuban/UI/mainwindow.py: Add blank line at the end because
88            file was not being read correctly building the Windows
89            distribution.
90    
91    2003-06-23  Jonathan Coles   <[email protected]>
92    
93            * Thuban/UI/mainwindow.py (MainWindow.About): Fix text.
94    
95            * Thuban/version.py: Temporarily update longversion for
96            the 0.8 release so that it doesn't have the cvs revision.
97    
98    2003-06-23  Jonathan Coles   <[email protected]>
99    
100            * Thuban/UI/common.py (ThubanBeginBusyCursor): Call wxSafeYield
101            to make sure that we don't create reentrant possibilities with
102            wxYield.
103    
104            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxBeginBusyCursor()
105            directly to avoid the wxSafeYield() call which generates an
106            OnPaint event causing infinite recursion. Don't try to catch
107            exception anymore. This was for before there were limits on map
108            scaling.
109    
110    2003-06-23  Bernhard Herzog  <[email protected]>
111    
112            Bug fix for RT #1961:
113    
114            * Thuban/Model/load.py (SessionLoader.start_derivedshapesource):
115            Register DerivedShapestores with the session
116    
117            * Thuban/Model/session.py (Session.Tables): Make sure each table
118            is only listed once.
119    
120            * test/test_load.py (TestJoinedTable.test): Add check_format call.
121            Update file contents to match the one written out.
122    
123    2003-06-20  Bernhard Herzog  <[email protected]>
124    
125            * test/xmlsupport.py (SaxEventLister.startElementNS)
126            (SaxEventLister.endElementNS): Do not include the qname. Python
127            2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
128            is (presumably incorrectly) None, whereas it's a string with the
129            element name in the later versions.
130    
131            * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
132            (TestEventList.test_even_list_namespace): Update tests to reflect
133            the new behaviour
134            (TestEventList.test_even_list_id_normalization): Fix doc-string
135    
136    2003-06-20  Jonathan Coles   <[email protected]>
137    
138            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
139            by deriving classes to determine if that layer supports shapes.
140            (Layer): Override HasShapes and return true.
141    
142            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
143            instead of a direct call to wx[Begin|End]CusyCursor().
144            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
145            table data.
146    
147            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
148            New. Wrappers around the wxWindows functions that allow us to
149            make additional calls such as wxYield which gives the native
150            system a chance to update the cursor correctly.
151    
152            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
153            instead of a direct call to wx[Begin|End]CusyCursor().
154    
155            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
156            instead of a direct call to wx[Begin|End]CusyCursor().
157            (MapCanvas.find_shape_at): Check if the current search layer
158            support shapes, otherwise go on to the next layer.
159    
160            * test/test_layer.py: Add tests in each type of layer for
161            HasClassification() and HasShapes()
162    
163    2003-06-20  Jonathan Coles   <[email protected]>
164    
165            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
166            turning on the busy cursor to allow the system to change the
167            cursor before we begin painting. This fixes a problem that
168            was occuring only under GTK. Fixes RTbug #1840.
169    
170    2003-06-20  Bernhard Herzog  <[email protected]>

178            sources they depend on.
179            (SessionSaver.__init__): Add idmap instance variable to map from
180            objects to the ids used in the file.

192            errors in the files are discovered
193            (SessionLoader.__init__): Define dispatchers for elements with a
194            thuban-0.8 namespace too.

208            * Thuban/Model/session.py (Session.DataContainers): New method to
209            return all "data containers", i.e. shapestores and tables

241            (SaveSessionTest.test_dbf_table)
242            (SaveSessionTest.test_joined_table): New test cases for saving the
243            new data sources structures.
244            (TestStoreSort, MockDataStore): Classes to test the sorting of the

260            number of rows in the table. Address RTbug #1933.
261    
262            * test/test_layer.py (TestLayer.test_derived_store): Add
263            a test for the new exception in DerivedShapeStore.__init__.

306    
307    2003-06-20  Jonathan Coles   <[email protected]>
308    
309            This is mainly about fixing RTbug #1949.
310    
311            * Thuban/Model/classification.py: Remove "from __future__"
312            import statement since python 2.2 is the earliest supported
313            version.
314    
315            * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
316            Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES

328            is None.
329    
330    2003-06-19  Bernhard Herzog  <[email protected]>
331    
332            Move version specific load tests to their own file.
333    
334            * test/test_load.py: Expand the doc-string to explain a bit how to
335            handle file format changes.
336            (TestClassification.test): Update the docstring as this test is
337            not about Thuban 0.2 anymore.

341    
342    2003-06-19  Bernhard Herzog  <[email protected]>
343    
344            Add XML validation to some of the tests. Validation will only be
345            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
346            To make the DTD available to the test cases it's moved into
347            Resources/XML
348    
349            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
350            for versions up to and including 0.2. Two slight changes: added an
351            encoding specification and fixed the comment which refered to
352            GRASS, not Thuban
353    
354            * test/xmlsupport.py: New support module for tests involving XML.
355            Currently there's a mix-in class for XML validation.
356    
357            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
358    
359            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
360            so that we can validate the
361            (SaveSessionTest.testEmptySession)
362            (SaveSessionTest.testSingleLayer)
363            (SaveSessionTest.testSingleLayer)
364            (SaveSessionTest.testLayerProjection)
365            (SaveSessionTest.testRasterLayer)
366            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
367    
368            * test/runtests.py (main): Call print_additional_summary instead
369            of print_garbage_information
370    
371            * test/support.py (resource_dir): New function to return the
372            "Resource" subdirectory
373            (print_additional_summary): New function to combine several
374            summary functions
375            (run_tests): Use print_additional_summary instead of calling
376            print_garbage_information directly
377    
378    2003-06-19  Bernhard Herzog  <[email protected]>
379    
380            * Doc/thuban.dtd (classification): Correct the content model of
381            the classification element.
382            (projection): Add the "name" attribute
383    
384    2003-06-19  Frank Koormann   <[email protected]>
385    
386            MERGE from the greater-ms3 branch.
387    
388            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
389            scale if projection is latlong to get better estimate.
390    
391            Fix problem of hidden properties dialog under windows after double
392            click on layer tree:
393            The tree control always gets an Expanded / Collapsed event after
394            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
395            raises the already displayed window.
396    
397            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
398            raiseProperties initialized to prevent endless loops
399            (LegendTree._OnItemActivated): Depending on self.raiseProperties
400            simply raise the properties or open the dialog and issue a second
401            event.
402    
403    2003-06-18  Jonathan Coles   <[email protected]>
404    
405            * setup.py: Fix a few problems that occured under Windows.
406    
407    2003-06-18  Jonathan Coles   <[email protected]>
408    
409            When Thuban loaded the map was redrawn twice because the
410            legend was being opened after the mainwindow was created
411            and not during its creation. This meant the map was drawn
412            initially and then had to be redrawn when the legend
413            caused the display to change. Now the legend is opened
414            in the mainwindow constructor which resolves this issue.
415    
416            Also, although we were checking for the existence of
417            gdal and gdalwarp modules, the gdalwarp extension was
418            still being compiled (which may fail if the system doesn't
419            have gdal installed). the build_ext command to setup.py
420            now accepts the flags --with-gdal and --without-gdal.
421            If --without-gdal is specified setup.py will try to
422            use the gdal parameters specified by gdal-config. Under
423            windows, those parameters have to be set in setup.py
424            as with proj4 an wxWindows.
425    
426            * setup.py: Use a list instead of seperate variables for
427            extension parameters so we can create a generic function
428            that runs an appropriate *-config script.
429            (run_cs_script): Renamed from run_wx_script and modified
430            to accept a second argument which is a list of lists to
431            be filled in by the values returned from running the command.
432            (thuban_build_ext): New. Extends the build_ext command and
433            provides the options --with-gdal/--without-gdal which then
434            optionally includes the gdalwarp extension.
435    
436            * Thuban/Model/resource.py: First check if we can import
437            the gdalwarp Thuban extension before checking for gdal.
438            Also added some comments.
439            
440            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
441            the map is None which may be the case if none has been loaded
442            yet.
443    
444            * Thuban/UI/main.py (main): Remove call to ShowLegend.
445    
446            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
447    
448            * Thuban/UI/renderer.py: Check for gdal support before importing
449            gdalwarp.
450            (MapRenderer.render_map): Only try to optimize if we have gdal
451            support otherwise nothing will get drawn.
452    
453            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
454            during startup before a map has been created. Check if map is None
455            before using it and do nothing if it is.
456    
457    2003-06-17  Jonathan Coles   <[email protected]>
458    
459            Fix the problem with raster layers under Windows that caused
460            Thuban to crash. The view should respond to layer projection
461            changed events to update the display. Changes to a projection
462            should not cause the map to be set to full extent.
463            
464            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
465            current_map_proj to remember the current map projection so that
466            when the projection changes we know what the previous projection
467            was.
468            (MapCanvas.SetMap): Unsubscribe and subscribe to
469            LAYER_PROJECTION_CHANGED events.
470            (MapCanvas.projection_changed): Split into two methods that respond
471            to map and layer projection changes.
472            (MapCanvas.map_projection_changed): New. Takes the current view and
473            projects it using the new projection. This does not cause the
474            map to be redrawn at full extent.
475            (MapCanvas.layer_projection_changed): New. Cause a redraw which
476            will draw each layer in its new projection.
477            
478            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
479            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
480            under Windows.
481            
482            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
483            to twice sizeof(void*) because there are two digits for each
484            hex byte.
485    
486    2003-06-16  Bernhard Herzog  <[email protected]>
487    
488            Update to the layer interface: Direct access to the table,
489            shapetable, shapefile and filename attributes is now actively
490            deprecated by issuing deprecation warnings for all places where
491            this happens.
492    
493            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
494            to the instance variables table, shapetable, shapefile and
495            filename via __getattr__ so that we can issue a deprecation
496            warning.
497            (Layer.SetShapeStore): Don't set the deprecated instance variables
498            any more
499            (Layer.SetShapeStore): Don't use deprecated layer instance
500            variables
501            (Layer.Destroy): No need to explicitly remove the instance
502            variables any more
503            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
504            instance variables
505    
506            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
507            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
508            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
509            use deprecated layer instance variables
510    
511            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
512            deprecated layer instance variables
513    
514            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
515            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
516            instance variables
517    
518            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
519            deprecated layer instance variables
520    
521            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
522            deprecated layer instance variables
523    
524            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
525            deprecated layer instance variables
526    
527            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
528            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
529            variables
530    
531            * test/runtests.py (main): Turn Thuban's deprecation warnings into
532            errors so that they're cought by the tests
533    
534            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
535            layer instance variables
536    
537    2003-06-16  Jonathan Coles   <[email protected]>
538    
539            Fix a problem under Windows whereby if the user double-clicks on a
540            layer in the legend that tree item will expand or collapse as well
541            as open the layer properties dialog. The state of the tree item
542            should not be affected.
543    
544            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
545            preventExpandCollapse and subscribe to expanding and collapsing
546            events.
547            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
548            collapsing events and will veto the event if it has been triggered
549            by the user double clicking on a layer.
550            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
551            that an expanding/collapsing event should be vetoed.
552    
553    2003-06-13  Bernhard Herzog  <[email protected]>
554    
555            * Thuban/UI/classifier.py (Classifier.OnClose)
556            (Classifier.map_layers_removed)
557            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
558            in OnClose and not in map_layers_removed or
559            layer_shapestore_replaced to make sure it always happens when the
560            dialog is closed
561    
562    2003-06-13  Jonathan Coles   <[email protected]>
563    
564            This puts back a fix for Windows where a panel is needed so that
565            the background of the table view appears correctly.
566    
567            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
568            object that can be used by derived classes to place any
569            controls (including the grid) onto.
570            (QueryTableFrame.__init__): Use the panel as the parent window
571            for all the controls. Reparent the grid so that the panel is
572            the parent. Call UpdateStatusText() to correctly initialize
573            the status bar.
574    
575    2003-06-13  Jonathan Coles   <[email protected]>
576    
577            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
578            from wxFrame (as opposed to wxDialog like the other classes)
579            but otherwise behaves like the other classes. This is needed
580            for the TableView which isn't really a dialog and needs to
581            have a status bar and control buttons.
582    
583            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
584            instance variable to keep track of how many rows are selected.
585            Subscribe once to the the events we are interested in.
586            (ThubanGrid.OnRangeSelect): Only handle event if event handling
587            hasn't been turned off.
588            (ThubanGrid.OnSelectCell): Only handle event if event handling
589            hasn't been turned off.
590            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
591            as an event listener (which changes the event handler stack)
592            simply set an instance variable to False. This is checked in
593            the event handlers.
594            (ThubanGrid.GetNumberSelected): Return the number of currently
595            selected rows.
596            (TableFrame): Inherit from ThubanFrame so we can have a
597            status bar and control buttons.
598            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
599            Explicitly set which items are selected in the operator choice and
600            action choice so there is always a valid selection. Fixes RTbug #1941.
601            Subscribe to grid cell selection events so we can update the
602            status bar.
603            (QueryTableFrame.UpdateStatusText): Update the status bar with
604            how many rows are in the grid, how many columns, and how many
605            rows are selected.
606            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
607            Call UpdateStatusText when cells are (de)selected.
608            (QueryTableFrame.OnQuery): Use the string value in the value
609            combo if either the selected item index is 0 or if the string
610            cannot be found in the predefined list (this happens if the
611            user changes the text). Fixes RTbug #1940.
612            Only turn off the grid event listeners if there a query comes
613            back with a none empty list of ids. in the case that the list
614            is empty this causes a grid.ClearSelection() call to actually
615            clear the grid selection which causes the selected items in
616            the map to be deselected. Fixes RTbug #1939.
617    
618            * test/test_save.py (XMLWriterTest.Encode): Check return values.
619            Fixes RTbug #1851.
620    
621    2003-06-13  Bernhard Herzog  <[email protected]>
622    
623            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
624            self.selected_shape with the current selection to make sure the
625            contents of the dialog are up to date when it's shown for the
626            first time.
627            The dialog used to work without this by luck. The recent fix to
628            the connector module 'broke' a 'feature' the identify view was
629            relying on, i.e that subscribing to a message in response to
630            receiving a message of that type would mean that the new
631            subscriber would also be called for the same message.
632            
633    2003-06-12  Jonathan Coles   <[email protected]>
634    
635            * extensions/thuban/gdalwarp.cpp: Removed debug printing as
636            the image is rendered. Fixes RTbug #1937.
637    
638    2003-06-12  Jonathan Coles   <[email protected]>
639    
640            * Thuban/Lib/fileutil.py: As is done under Windows, create the
641            user directory if it doesn't exist on a posix system.
642            Fixes RTbug #1815.
643    
644            * Thuban/Model/resource.py (get_user_proj_files): Moved the
645            called to get_application_dir here, so that the directory
646            will only be called if this method is invoked.
647    
648            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
649            the projfilepath if no projection is selected.
650    
651    2003-06-12  Jonathan Coles   <[email protected]>
652    
653            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
654            the scalebar if the current map has no projection set.
655    
656            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
657            projfilepath label to just the basename of the projection file
658            rather than include the entire path.
659    
660            * Thuban/Model/resource.py: Fix missed proj functions that
661            needed to be renamed.
662    
663    2003-06-12  Jonathan Coles   <[email protected]>
664    
665            * Thuban/Model/classification.py: Removed assert statements that
666            tested if the variable was an instance of Color.
667    
668            * Thuban/Model/color.py (Color): Remove commented code that isn't
669            used.
670            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
671            Fixes RTbug #1835.
672            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
673            Needed now that the class doesn't inherit from Color.
674    
675    2003-06-12  Jonathan Coles   <[email protected]>
676    
677            * test/test_save.py (XMLWriterTest.testEncode): Explicitly
678            check unicode strings.
679    
680            * test/test_layer.py: Check for existence of gdal.
681    
682    2003-06-12  Jonathan Coles   <[email protected]>
683        
684            * Thuban/Model/xmlreader.py: New. Contains the XMLReader class
685            that was in load.py
686    
687            * Thuban/Model/xmlwriter.py: New. Contains the XMLWriter class
688            that was in save.py
689    
690    2003-06-12  Jonathan Coles   <[email protected]>
691    
692            This is largely a collection of bug fixes. We also handle the
693            case where gdal is not on the system. The XMLReader and XMLWriter
694            classes were moved into there own files to resolve some circular
695            import references and because they shouldn't really be in the
696            file that is dediciated to reading/writing session files since
697            they are also used elsewhere.
698    
699            * Thuban/Model/classgen.py: Renamed functions to follow the
700            function_names_with_underscores style. Fixes RTbug #1903.
701            (calculate_quantiles): Raise ValueError if 'percents' is invalid.
702    
703            * Thuban/Model/layer.py: Import gdal only if it available.
704            (RasterLayer): Handle the case where the gdal library is unavailable.
705            Addresses RTbug #1877.
706    
707            * Thuban/Model/load.py (XMLReader): Moved into seperate file
708            xmlreader.py.

734            function_names_with_underscores style.
735            (has_gdal_support): New function that returns true if the gdal
736            library is available. Addresses RTbug #1877.
737    
738            * Thuban/UI/application.py (ThubanApplication.OpenSession):
739            Display a message box if the gdal library is not available, but
740            only if there are any layers that would use it. Addresses RTbug #1877.
741    
742            * Thuban/UI/classgen.py: Use renamed projection resource functions.
743            (GenUniformPanel.__CalcStepping): Fix a slight discrepency
744            when using integers versus floats.
745    
746            * Thuban/UI/mainwindow.py (_has_gdal_support): New. Used to
747            determine if the "Add Image Layer" menu option should be
748            greyed out or not. Addresses RTbug #1877.
749    
750            * Thuban/UI/projdialog.py: Use renamed projection resource functions.
751    
752            * Thuban/UI/renderer.py (MapRenderer.render_map): Only try to
753            optimize if a raster layer is visible. Fixes RTbug #1931.
754            Only draw the raster layer if the gdal library is available.
755            Addresses RTbug #1877.
756    
757            * test/test_classgen.py: Add tests for generate_singletons,
758            generate_uniform_distribution, generate_quantiles. Fixes RTbug #1903.
759            (test_calculate_quantiles): Fix some tests to catch the new
760            ValueError that is raised.
761    
762            * test/test_proj.py: Use renamed projection resource functions.
763    
764            * test/test_save.py (SaveSessionTest.testClassifiedLayer): New
765            test for saving classified layers. Fixes RTbug #1902.
766            (XMLWriterTest): New. Tests the XMLWriter class. Fixes RTbug #1851.
767    
768    2003-06-12  Jan-Oliver Wagner <[email protected]>
769    
770            Fix for http://intevation.de/rt/webrt?serial_num=1900.
771    
772            * Thuban/UI/multiplechoicedialog.py: New. A multiple choice dialog.
773    
774            * Thuban/UI/mainwindow.py: import wxMultipleChoiceDialog from
775            multiplechoicedialog.py rather than from the wxPython library.

782    2003-06-11  Frank Koormann  <[email protected]>
783    
784            * Thuban/Lib/fileutil.py (get_application_dir): New function to

817    
818            * Thuban/Model/layer.py (Layer.SetShapeStore): Send
819            LAYER_SHAPESTORE_REPLACED when the shapestore changes. A
820            LAYER_CHANGED will still be sent if the classification changes.
821    
822            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
823            parameter so we can subscribe to some of its messages
824            (Classifier.__init__): Subscribe to the map's MAP_LAYERS_REMOVED

857            * Thuban/UI/identifyview.py (IdentifyView.__init__):
858            Layout reimplemented without panel. Make life easier to fit the list
859            in the dialog.
860    
861    2003-06-05  Frank Koormann  <[email protected]>
862    
863            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
864            once on initialisation (Former implementation resulted in multiple
865            entries for each projection).
866            (ProjFrame.__FillAvailList): selectProj as second optional parameter,
867            if set, select the projection found under the specified name. This
868            overwrites any other selection estimate.
869            Removed projchoice filling from this method.
870            (ProjFrame._OnSave, ProjFrame._OnAddToList):

888    2003-06-04  Bernhard Herzog  <[email protected]>
889    
890            Do not cache the values returned by the tree widget's
891            GetFirstChild and GetNextChild methods because it led to lots of
892            segfaults. The new way requires more brute force but is more
893            reliable.
894    
895            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
896            variable layer2id

901            Use find_layer instead of layer2id
902            (LegendTree.__RemoveLayer, LegendTree.__AddLayer): No need to
903            update layer2id anymore
904            (LegendTree._OnMsgMapLayersRemoved)

929    
930            * test/test_base.py (SomeTitledObject): Derive from Modifiable
931            instead of Publisher to reflect reality better and to accomodate
932            the fact that SetTitle now calls changed instead of issue
933    
934    2003-06-02  Bernhard Herzog  <[email protected]>
935    
936            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource
937            acquisition has to happen before the try in a try-finally.
938    
939    2003-06-02  Bernhard Herzog  <[email protected]>
940    
941            * Thuban/UI/legend.py (LegendTree._OnMsgMapLayersRemoved): It's
942            possible that a layer is removed that is not currently selected in
943            the legend so don't check for this.
944    
945    2003-05-30  Bernhard Herzog  <[email protected]>
946    
947            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
948            variables to None that have direct or indirect references to

958    
959            * Thuban/UI/legend.py (LegendTree.__init__): New instance variable
960            changing_selection to indicate whether the LegendTree code itself
961            is currently changing the selection
962            (LegendTree.normalize_selection): New method to normalize the
963            selection by selecting the layer item even if the user clicked on
964            the classification.
965            (LegendTree._OnSelChanged): normalize the selection. This works
966            around a bug in wx which doesn't keep track of the selection
967            properly when subtrees are deleted.

987            of the ClassGenerator class. Put try/finally blocks around
988            code that uses wxBeginBusyCursor()/wxEndBusyCursor(). Fixes
989            RTBug #1904.
990    
991            * Thuban/UI/classifier.py: Remove unused import of ClassGenerator.
992    
993            * Thuban/UI/legend.py: The legend was cleared and repopulated any
994            time something changed which caused some state to be lost such
995            as which children were expanded or collapsed. Fixes RTBug #1901.
996            (LegendTree._OnMsgMapLayersAdded): Add only new layers.

1007            (LegendTree.__RemoveLayer): Remove a layer from the legend.
1008            (LegendTree.DeleteChildren): New, overrides wxTreeCtrl method.
1009            Should only be called with the id of a layer branch.

1023    
1024            * extensions/thuban/gdalwarp.cpp: Removed code that allowed gdalwarp
1025            to be compiled as a standalone app. Now the code can only be
1026            called from Python which simplifies the parameter passing.
1027            (ProjectRasterFile): Handle Python arguments. Remove code that
1028            checks for a destination dataset. Add more clean up code.
1029

1067    
1068            * Thuban/Model/layer.py (Layer.TreeInfo): Fixed a bug (a layer

1249            Remove the Precision methods again. They're too DBF specific to be
1250            part of the table interface and they're only used in table_to_dbf

1555            * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
1556            (ProjFrame.__DoOnProjAvail): Determine position of current projection
1557            using the wxListBox.FindString() method. Still a problem (#1886)
1558    
1559            * Thuban/UI/classifier.py
1560            (Classifier.__init__, SelectPropertiesDialog.__init__)
1561    
1562            * Thuban/UI/classgen.py (ClassGenDialog.__init__,
1563            (ClassGenDialog.__DoOnGenTypeSelect): Moved initialization of the
1564            different classification types from here to __init__.
1565            (GenUniquePanel.__init__): Set the column width of the first field
1566            in the Field ListCtrl to the full width.
1567    
1568            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Rename 'Save As'
1569            Button to 'Export'. Center Buttons in Selection Box, set Focus to
1570            Grid.
1571            (LayerTableFrame.OnKeyDown()): New, bound to the grid with EVT_KEY_DOWN,
1572            changes focus to the Selection when pressing "Alt-S".
1573    
1574            * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
1575            the text if not visible. The italic font sometimes exceeds the
1576            rendering area.
1577    
1578    2003-05-21  Jonathan Coles   <[email protected]>
1579    
1580            * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
1581            to OnClose so that Thuban closes correctly.
1582    
1583            * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
1584            DockFrame.OnClose, not DockFrame._OnClose.
1585    
1586    2003-05-21  Jonathan Coles   <[email protected]>
1587    
1588            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
1589            references to 'inf' and use new Range __init__ to pass floats
1590            directly rather than converting them to strings first.
1591            Fixes RTBug #1876.
1592    
1593            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
1594            Use new Range ___init__ to pass floats.
1595    
1596            * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
1597            filename is a valid image file. Throw IOError otherwise.
1598    
1599            * Thuban/Model/range.py: Brought over new Range from SciParam that
1600            is immutable and has an __init__ which can accept floats.
1601    
1602            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
1603            into try block. AddLayer doesn't throw any exceptions anymore.
1604            (MainWindow.AddRasterLayer): Move constructor of RasterLayer into
1605            try block.
1606    
1607            * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as
1608            the first item in choices. Fixes RTBug #1882.
1609    
1610            * Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale
1611            has gone to 0 which is a serious problem. abort.
1612            (MapRenderer.draw_raster_layer): Catch IOError seperately and
1613            print the error from GDAL.
1614    
1615            * Thuban/UI/tableview.py (TableGrid.__init__): Call
1616            ToggleEventListeners to turn on listening.
1617            (TableGrid.ToggleEventListeners): New. Turns event listening on
1618            and off so as to prevent excessive messages.
1619            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
1620            to suppress excessive messages when selecting many rows.
1621            Fixes RTBug #1880.
1622    
1623            * Thuban/UI/view.py: Added checks against if scale == 0. This
1624            is a serious problem that can occur when an image without
1625            geo data is loading and causes the map projection bounds to
1626            go to infinity. Right now, the solution is to simply try
1627            to recover.
1628    
1629            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
1630            to set the MFILEReceiver attributes even if the data is NULL.
1631    
1632            * extensions/thuban/gdalwarp.cpp: Improved the error handling
1633            and passed GDAL messages back up to the Python layer. Also
1634            tried to fix some memory leaks that were present in the original
1635            utility but didn't matter because the program aborted.
1636    
1637            * test/test_range.py: Copied over tests from SciParam. Removed
1638            tests against importing. Fixes RTBug #1867.
1639    
1640    2003-05-21  Bernhard Herzog  <[email protected]>
1641    
1642            * test/test_load.py: Remove unused imports and restructure the
1643            test code
1644            (LoadSessionTest): Split into one class for each test and turn
1645            LoadSessionTest itself into the base class for all such session
1646            tests.
1647            (ClassificationTest): New base class for load tests that test
1648            classifications
1649            (TestSingleLayer, TestLayerVisibility, TestClassification)
1650            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
1651            for the individual tests
1652    
1653            * test/support.py (FileLoadTestCase.filename): New base class for
1654            file loading tests
1655    
1656    2003-05-21  Jan-Oliver Wagner <[email protected]>
1657    
1658            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
1659            Mercator' to 'UTM Zone 32' as a more convenient example.
1660            Added 'Gauss Krueger Zone 6'.
1661    
1662            * Data/iceland_sample_raster.thuban: political polygon now
1663            filled transparent to have the raster image visible at once.
1664    
1665    2003-05-21  Frank Koormann  <[email protected]>
1666    
1667            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
1668            OnClose() to keep in sync with extensions. Internally Thuban
1669            still uses "underscored" names.
1670    
1671    2003-05-20  Jonathan Coles   <[email protected]>
1672    
1673            This puts back Raster layer support. These layers support projections
1674            through the GDAL library. Currently, the CVS version is being used.
1675            There are no Debian packages available although this may change soon.
1676            A GDAL driver was extended to support writing to memory rather to
1677            files.
1678    
1679            There is still some work that needs to be done, such as some error
1680            handling when loading invalid images or when there is a problem
1681            projecting the image. This putback simply checks in the majority
1682            of the work.
1683    
1684            * setup.py: Add gdalwarp library extension.
1685    
1686            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
1687            Defaults to False, but can be overridden by subclasses if they
1688            support classification.
1689            (RasterLayer): New. Defines a new layer that represents an
1690            image.
1691    
1692            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
1693            tag handler.
1694            (SessionLoader.start_layer): Encode the filename.
1695            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
1696            New. Supports reading a rasterlayer tag.
1697    
1698            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
1699    
1700            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
1701            get a string in Latin1. If we get such as string convert it to
1702            unicode first, otherwise leave if alone before encoding.
1703            (SessionSaver.write_layer): Add support for writing both Layers
1704            and RasterLayers.
1705    
1706            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
1707            The right argument may not be a string, it could also be a Column.
1708    
1709            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
1710            Make initial window size 600x400. Fixes RTBug #1872.
1711    
1712            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
1713            the dialog is constructed so that we can support layers that
1714            do not have classifications.
1715            (Classifier._OnTry): Only build a classification if the layer
1716            supports one.
1717    
1718            * Thuban/UI/legend.py: Change all checks that a layer is an
1719            instance of Layer into checks against BaseLayer.
1720            (LegendTree.__FillTreeLayer): Only add children to a branch if
1721            the layer supports classification.
1722    
1723            * Thuban/UI/mainwindow.py (MainWindow.NewSession,
1724            MainWindow.OpenSession): Don't proceed with an action if the
1725            user chooses Cancel when they are asked to save changes.
1726            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
1727            user to select an image file. Create a new RasterLayer and add
1728            it to the map.
1729    
1730            * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
1731            for rendering RasterLayer layers.
1732            (MapRenderer.draw_raster_layer): Actually method that calls
1733            the GDALWarp python wrapper and constructs an image from the
1734            data returned.
1735    
1736            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the
1737            Choices symbols to match those used in the table query method.
1738            Replace deprecated method calls on table with new method names.
1739    
1740            * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
1741            how small the scale can get. This still needs more testing.
1742    
1743            * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
1744            Provides a driver to output in .bmp format.
1745    
1746            * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h:
1747            New. Provides IO routines which write to memory, rather than a file.
1748    
1749            * extensions/thuban/gdalwarp.cpp: New, but basically a direct copy
1750            of the gdalwarp utility provided in GDAL. Added function calls
1751            that can be accessed from python.
1752    
1753            * Data/iceland_sample_raster.thuban: New. Sample file that uses
1754            a raster layer.
1755    
1756            * Data/iceland/island.tfw, Data/iceland/island.tif: New. Raster
1757            layer image data.
1758    
1759            * Doc/thuban.dtd: Added rasterlayer attribute definition.
1760    
1761            * test/test_layer.py, test/test_load.py, test/test_save.py: Added
1762            tests associated with the raster layer code.
1763    
1764            * test/test_transientdb.py
1765            (TestTransientTable.test_auto_transient_table_query): Added a test
1766            for using a Column object as the "right" parameter to a query.
1767    
1768    2003-05-19  Frank Koormann  <[email protected]>
1769    
1770            * Thuban/version.py (get_changelog_date):
1771            Catch exceptions if ChangeLog does not exist.
1772    
1773            * Thuban/UI/view.py (MapCanvas.Export): Bugfix
