1    2003-05-12  Frank Koormann <[email protected]>
2            
3            * Thuban/Model/save.py (XMLWriter.encode()): Explicite call to unicode
4            and latin1. Fixes #1851 finally.
5    
6    2003-05-09  Jonathan Coles   <[email protected]>
7    
8            Introduces Range class from SciParam into the ClassGroupRange class,
9            and such ranges can now be saved and loaded from disk.
10    
11            Quantiles are now available in the Classification Generator.
12    
13            Initial support for building Queries on a table. Doesn't do anything
14            but run some tests.
15    
16            * Thuban/Model/classification.py: Explicit imports.
17            (ClassGroupRange): Use the Range class to store the underlying
18            range information. The interface remains the same, except for
19            GetRange(), and you can also supply a Range object as the min
20            parameter to SetRange or __init__.
21    
22            * Thuban/Model/load.py (XMLReader.encode): New. Encodes the given
23            string appropriately for use in Thuban. Fixes RTbug #1851.
24            (SessionLoader.end_projection): Handle the context of the
25            projection tag a bit better by looking at what objects are not
26            None. There was an assumption that a projection tag for a map
27            could occur before any layers.
28            (SessionLoader.start_clrange): Provide backward compatibility for
29            reading min/max values as well as the new range parameter.
30    
31            * Thuban/Model/map.py: Explicit imports.
32    
33            * Thuban/Model/resource.py: Import _.
34            (ProjFileSaver.write): write header using projfile.dtd.
35    
36            * Thuban/Model/save.py: Explicit imports.
37            (XMLWriter.encode): New. Encode the given string from a format
38            used by Thuban into UTF-8. Fixes RTbug #1851.
39    
40            * Thuban/UI/classgen.py: Explicit imports.
41            (ClassGenDialog.__init__): Clean up the code and add support
42            for Quantiles.
43            (ClassGenDialog.OnOK): Add support for Quantiles.
44            (GenQuantilesPanel): New. Input panel for Quantiles.
45            (ClassGenerator, CustomRamp, MonochromaticRamp, GreyRamp, RedRamp,
46            GreenRamp, BlueRamp, HotToColdRamp): Move to Thuban/Model/classgen.py
47    
48            * Thuban/Model/classgen.py: New. Contains all the classes named above.
49    
50            * Thuban/UI/classifier.py: Explicit imports.
51            (ClassTable.GetValueAsCust, ClassTable.__ParseInput,
52            ClassTable.SetValueAsCustom): Reworked to use new Range class.
53    
54            * Thuban/UI/legend.py: Explicit imports.
55    
56            * Thuban/UI/mainwindow.py: Add support for the Join Dialog. Added
57            a Table menu and associated method calls.
58            (MainWindow.choose_color): Removed. No longer needed.
59    
60            * Thuban/UI/projdialog.py (ProjFrame.__VerifyButtons): Save button
61            should be disabled if no projection is selected in the available
62            list.
63    
64            * Thuban/UI/renderer.py: Explicit imports.
65    
66            * Thuban/UI/tableview.py (TableGrid.OnRangeSelect): Fix some issues
67            with correctly selecting the rows and issuing the right events.
68            Be sure to call Skip() to allow the grid to do some of its own
69            handling which allows the rows to actually be selected.
70            (LayerTableGrid.select_shapes): Rename from select_shape. Supports
71            selecting multiple shapes.
72            (LayerTableFrame): Support for building Queries.
73            (LayerTableFrame.select_shapes): Allow multiple shapes to be selected.
74    
75            * Thuban/UI/tree.py: Explicit imports.
76    
77            * Thuban/UI/view.py (MapCanvas): Delegate "SelectedShapes" so the
78            table view can call it.
79    
80            * test/test_classification.py: Explicit imports.
81            (TestClassification.test_ClassGroupRange): Fix test for new
82            Range class.
83    
84            * Doc/thuban.dtd: Add range parameter for clrange.
85    
86            * Thuban/Model/range.py: Taken from SciParam. Used as the underlying
87            object in ClassGroupRange, and also uesd for inputting ranges in
88            the classifer table and elsewhere.
89    
90            * Thuban/UI/join.py: New. Initial Join dialog. No real functionality
91            yet.
92

212            Convert all table users to use the new table interface. This only
213            covers Thuban itself, not GREAT-ER or other applications built on
214            Thuban yet, so the compatibility interface stays in place for the
215            time being but it now issues DeprecationWarnings.
216    
217            Finally, the new Table interface has a new method, HasColumn.
218    
219            * Thuban/Model/table.py (OldTableInterfaceMixin): All methods
220            issue deprecation warnings when they're. The warnings refer to the

224    
225            * test/test_table.py: Ignore the deprecation warnings for the old
226            table in the tests in this module. The purpose of the tests is to

229            * test/test_transientdb.py
230            (TestTransientTable.run_iceland_political_tests): Use the
231            constants for the types. Add a test for HasColumn

251            to new table interface
252    
253            * Thuban/Model/transientdb.py (TransientTableBase.HasColumn)
254            (AutoTransientTable.HasColumn): Implement the new table interface
255            method
256            (AutoTransientTable.ReadRowAsDict, AutoTransientTable.ValueRange)
257            (AutoTransientTable.UniqueValues): Adapt to new table interface
258    
259            * Thuban/Model/layer.py (Layer.SetShapeStore, Layer.GetFieldType):
260            Adapt to new table interface
261

278    
279            * Resources/Bitmaps/fulllayerextent.xpm,
280            Resources/Bitmaps/fullselextent.xpm: Bitmaps for layer and selection
281            extent. These are just place holders for the real bitmaps.
282    
283            * Thuban/Model/layer.py (Shape): Since a Shape is immutable only
284            calculate the bounding box once (the first time compute_bbox() is
285            called).
286            (Layer.ShapesBoundingBox): New. Given a list of shape ids, return
287            the bounding box for the shapes in lat/long coordinates.
288    
289            * Thuban/UI/mainwindow.py: Added new "Full selection extent" menu
290            option.
291            (MainWindow.has_selected_shapes): New. Returns true if there are
292            any selected shapes.
293            (MainWindow.FullSelectionExtent): New. Calls
294            MapCanvas.FitSelectedToWindow() when the user selects the menu option.
295            (_has_selected_shapes): New. Returns true if there are any
296            selected shapes.
297

305    
306            * test/test_layer.py (TestLayer.test_arc_layer): Add some tests
307            for Layer.ShapesBoundingBox().
308

325    
326    2003-05-05  Bernhard Herzog  <[email protected]>
327    
328            Convert the table implementations to a new table interface. All
329            tables use a common mixin class to provide backwards compatibility
330            until all table users have been updated.
331    
332            * Thuban/Model/table.py (OldTableInterfaceMixin): Mixin class to
333            provide backwards compatibility for table classes implementing the
334            new interface
335            (DBFTable, MemoryTable): Implement the new table interface. Use
336            OldTableInterfaceMixin as base for compatibility
337            (DBFColumn, MemoryColumn): New. Column description for DBFTable

344            with the new table interface.
345    
346            * test/test_table.py: Document the all tests in this file as only
347            for backwards compatibility. The equivalent tests for the new
348            interface are in test_memory_table.py and test_dbf_table.py
349            (MemoryTableTest.test_read): field_info should be returning tuples
350            with four items
351            (MemoryTableTest.test_write): Make doc-string a more precise.
352    
353            * Thuban/Model/transientdb.py (TransientTableBase): Convert to new
354            table interface. Derive from from OldTableInterfaceMixin for
355            compatibility.
356            (TransientTableBase.create): New intance variable column_map to
357            map from names and indices to column objects
358            (TransientTable.create): Use the new table interface of the input
359            table
360            (AutoTransientTable): Convert to new table interface. Derive from
361            from OldTableInterfaceMixin for compatibility.
362            (AutoTransientTable.write_record): Removed. It's not implemented
363            yet and we still have to decide how to handle writing with the new
364            table and data framework.
365    
366            * test/test_transientdb.py
367            (TestTransientTable.run_iceland_political_tests)
368            (TestTransientTable.test_transient_joined_table): Use the new
369            table interface
370    
371    2003-05-05  Jonathan Coles   <[email protected]>
372    
373            This is namely a collection of UI updates to improve user interactivity.
374            Tabbing between controls now exists and you can use ESC to close dialog
375            boxes; ENTER will active the default button.
376    
377            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Rearrange the
378            order that the controls are created so that tabbing works correctly.
379            (ClassGenDialog.OnOK): Renamed from _OnGenerate() so that the
380            wxDialog can handle the default button correctly.
381            (ClassGenDialog.OnCancel): Renamed from _OnCloseBtn() for the
382            same reasons as for OnOK.
383            (GenUniformPanel._OnRetrieve): Call wxBeginBusyCursor/wxEndBusyCursor
384            when we ask the table for the maximum/minimum values of a field
385            which could take a very long time.
386    
387            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange the
388            order that the controls are created so that tabbing works correctly.
389            (SelectPropertiesDialog.__init__): Rearrange the order that the
390            controls are created so that tabbing works correctly.
391    
392            * Thuban/UI/dialogs.py: Copied NonModalDialog box and changed it
393            to derive from a wxDialog but behave like the original implementation
394            which was derived from a wxFrame. wxDialog provides useful key
395            handling functionality like ESC calling OnCancel and ENTER calling
396            OnOK which is lost with wxFrame.
397    
398            * Thuban/UI/mainwindow.py: Add "..." to menu items that will open
399            new dialogs.
400    
401            * Thuban/UI/projdialog.py (ProjFrame.__init__): Rearrange the
402            order that the controls are created so that tabbing works correctly.
403            (ProjFrame.OnApply): Renamed from _OnTry() to use wxDialog behaviour.
404            (ProjFrame.OnOK): Renamed from _OnOK() to use wxDialog behaviour.
405            (ProjFrame.OnCancel): Renamed from _OnClose() to use wxDialog behaviour.
406            (ProjPanel.__init__): Add "Airy" to the list of ellipsoids so we
407            can provide the "UK National Grid" as a default projection.
408            (UTMPanel.__init__): Rearrange the order that the controls are
409            created so that tabbing works correctly.
410    
411    2003-05-05  Bernhard Herzog  <[email protected]>
412    
413            * extensions/thuban/wxproj.cpp: Fix some of the comments.
414            (project_point): If a map projection but no layer projection is
415            given, convert degrees to radians before applying the map
416            projection.
417    
418            * Thuban/UI/tableview.py (TableGrid.disallow_messages)
419            (TableGrid.allow_messages): New methods to make it possible to
420            inhibit message sending.
421            (TableGrid.issue): Only send the message if not inhibited.
422            (LayerTableGrid.select_shape): Use the new methods to make sure
423            that no ROW_SELECTED message is sent while we're updating the
424            selected rows to match the selected shapes.
425    
426    2003-05-02  Jan-Oliver Wagner <[email protected]>
427    
428            Implementation of MemoryTable.
429    
430            * Thuban/Model/table.py (MemoryTable): New. Quite simple table
431            implementation that operates on a list of tuples. All of the data
432            are kept in the memory.
433    
434            * test/test_table.py (MemoryTableTest): New.
435    
436            * test/test_transientdb.py (SimpleTable): Removed.
437            (TestTransientTable.test_transient_joined_table,
438            (TestTransientTable.test_transient_table_read_twice): Replaced
439            SimpleTable by MemoryTable.
440    
441    2003-04-30  Jonathan Coles   <[email protected]>
442    
443            * Data/iceland_sample.thuban: Now contains correct projections
444            for each of the layers.
445    
446            * Resources/Projections/defaults.proj: Geographic projection
447            contains unit conversion parameter.
448    
449    2003-04-30  Jonathan Coles   <[email protected]>
450    
451            The most important part of this putback is the projection changes.
452            It should now be possible to specify the projection that a layer
453            is in and then specify a different projection for the map. The
454            projection dialog has an extra parameter for a geographic projection
455            which lets the user select if the input is in degrees or radians.
456    
457            * Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring
458            to say that the parameter is a tuple of unprojected
459            points (which is what the callers to this method were assuming).
460            Also, since the points are unprojected we need to projected them.
461    
462            * Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp,
463            LegendTree.MoveCurrentItemDown): If the layer or any of the layer's
464            groups are selected, move the layer up/down. Fixes RTbug #1833.
465    
466            * Thuban/UI/mainwindow.py: Move menu item map_rename up.
467    
468            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing
469            parameter in call to SetClientData.
470            (GeoPanel): Add support for selecting the units that the
471            source data is in (Radians or Degrees).
472    
473            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize
474            the rendering loop by reducing the number of if's, removing the
475            unnecessary try/except block, and checking if the old group
476            is the same as the new one (which happens a lot if there is
477            no classification, or lots of shapes are in the same group).
478    
479            * Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block
480            around the redraw routine to try to catch problems that the user
481            may create by selecting invalid projections for the data set and
482            map. Clears the display if there are any problems and prints the
483            error.
484            (MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled
485            rectangle.
486    
487            * extensions/thuban/wxproj.cpp (project_point): First invert the
488            supplied point (which should be in projected coordinates) using
489            the layer's projection and then project the point using the
490            map's projection.
491            (project_points): Use project_point() to project each point.
492    
493    2003-04-30  Jan-Oliver Wagner <[email protected]>
494    
495            * Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug:
496            don't set the Classification to None if the classfication field
497            is None (ie only a DEFAULT).
498    
499    2003-04-30  Bernhard Herzog  <[email protected]>
500    
501            * Thuban/UI/view.py: Fix some typos.
502    
503            * Thuban/UI/mainwindow.py (MainWindow.identify_view_on_demand): Do
504            not pop up the dialog if the selection becomes empty (this could
505            happen if e.g. a new selection is opened while the identify tool
506            is active and dialog had been closed)
507    
508    2003-04-30  Bernhard Herzog  <[email protected]>
509    
510            * Thuban/Model/transientdb.py (TransientTableBase.__init__): New
511            instance variable read_record_last_result
512            (TransientTableBase.read_record): Make sure reading the same
513            record twice works. The implementation uses the new instance
514            variable read_record_last_result
515    
516            * test/test_transientdb.py
517            (TestTransientTable.test_transient_table_read_twice): New test
518            case for the above bug-fix.
519    
520    2003-04-29  Jonathan Coles   <[email protected]>
521    
522            * Thuban/common.py: Removed. No longer needed Str2Num. RTbug #1832.
523    
524            * Thuban/UI/classgen.py: Remove all uses of Str2Num.
525    
526            * Thuban/UI/classifier.py: Remove all uses of Str2Num.
527            (ClassTable.SetValueAsCustom): Rename keyword argument in
528            ClassGroup* constructors to match argument name.
529    
530    2003-04-29  Bernhard Herzog  <[email protected]>
531    
532            * Thuban/Model/session.py (Session.Destroy): Explicitly close the
533            transient DB if it exists to make sure it doesn't leave a journal
534            file in the temp directory.
535    
536            * Thuban/Model/transientdb.py (TransientDatabase.close): Set
537            self.conn to None after closing the connection to make sure it's
538            not closed twice
539    
540    2003-04-29  Jonathan Coles   <[email protected]>
541    
542            Add a visible parameter in the layer XML tag. The default value is
543            "true". If anything other than "false" is specified we also assume
544            "true". Addresses RTbug #1025.
545    
546            * Doc/thuban.dtd: Add visible parameter to a layer.
547    
548            * Thuban/Model/layer.py (BaseLayer.__init__): Change default value
549            of visible from 1 to True.
550            (Layer.__init__): Change default value of visible from 1 to True.
551    
552            * Thuban/Model/load.py (SessionLoader.start_layer): Read visible
553            parameter.
554    
555            * Thuban/Model/save.py (SessionSaver.write_layer): Save visible
556            parameter.
557    
558            * test/test_load.py: Add new test data contents_test_visible.
559            (LoadSessionTest.setUp): save test data.
560            (LoadSessionTest.testLayerVisibility): Test if the visible flag
561            is loaded correctly.
562    
563            * test/test_save.py (SaveSessionTest.testSingleLayer): Add test
564            for saving an invisible layer.
565    
566    2003-04-29  Jonathan Coles   <[email protected]>
567    
568            * Thuban/UI/mainwindow.py (MainWindow.SetMap): Look up the
569            legend dialog box and tell it to change its map to the one
570            supplied to SetMap(). Fixes RTbug #1770.
571    
572    2003-04-29  Bernhard Herzog  <[email protected]>
573    
574            Next step of table implementation. Introduce a transient database
575            using SQLite that some of the data is copied to on demand. This
576            allows us to do joins and other operations that require an index
577            for good performance with reasonable efficiency. Thuban now needs
578            SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I
579            haven't tested that.
580            
581            * Thuban/Model/transientdb.py: New. Transient database
582            implementation.
583    
584            * test/test_transientdb.py: New. Tests for the transient DB
585            classes.
586    
587            * Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New
588            classes to help automatically remove temporary files and
589            directories.
590            (Session.__init__): New instance variables temp_dir for the
591            temporary directory and transient_db for the SQLite database
592            (Session.temp_directory): New. Create a temporary directory if not
593            yet done and return its name. Use AutoRemoveDir to have it
594            automatically deleted
595            (Session.TransientDB): Instantiate the transient database if not
596            done yet and return it.
597    
598            * Thuban/Model/data.py (ShapefileStore.__init__): Use an
599            AutoTransientTable so that data is copied to the transient DB on
600            demand.
601            (SimpleStore): New class that simply combines a table and a
602            shapefile
603    
604            * Thuban/Model/table.py (Table, DBFTable): Rename Table into
605            DBFTable and update its doc-string to reflect the fact that this
606            is only the table interface to a DBF file. Table is now an alias
607            for DBFTable for temporary backwards compatibility.
608    
609            * Thuban/UI/application.py (ThubanApplication.OnExit): Make sure
610            the last reference to the session goes away so that the temporary
611            files are removed properly.
612    
613            * test/test_load.py (LoadSessionTest.tearDown): Remove the
614            reference to the session to make sure the temporary files are
615            removed.
616    
617    2003-04-29  Bernhard Herzog  <[email protected]>
618    
619            * Thuban/Model/load.py (XMLReader.__init__, XMLReader.read): Turn
620            the __parser instance variable into a normal local variable in
621            read. It's only used there and read will never be called more than
622            once. Plus it introduces a reference cycle that keeps can keep the
623            session object alive for a long time.
624    
625    2003-04-29  Jonathan Coles   <[email protected]>
626    
627            * Thuban/Model/proj.py (Projection): Removed Set*() methods to make
628            Projection an immutable item. Fixes RTbug #1825.
629            (Projection.__init__): Initialize instance variables here.
630            (ProjFile.Replace): New. Replace the given projection object with
631            the new projection object. This solves the problem of needing the
632            mutator Projection.SetProjection() in the ProjFrame class and
633            allows a projection to change parameters without changing its
634            location in the file.
635    
636            * Thuban/UI/mainwindow.py (MainWindow.SaveSessionAs): Dialog should
637            be of type wxSAVE and should verify overwriting a file.
638    
639            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Use the new
640            ProjFile.Replace() method instead of the mutator
641            Projection.SetProjection(). Also requires that we reassign the
642            client data to the new projection.
643    
644            * test/test_proj.py (TestProjection.test): Test GetName() and
645            GetAllParameters()
646            (TestProjFile.test): Remove tests for Set*() methods. Add tests
647            for Replace().
648    
649    2003-04-25  Jonathan Coles   <[email protected]>
650    
651            * Thuban/Model/save.py (SessionSaver.write_projection): Make sure
652            to save the name of the projection.
653    
654            * test/test_save.py (SaveSessionTest.testLayerProjection): New
655            test to verify layer projections are saved correctly.
656    
657    2003-04-25  Jonathan Coles   <[email protected]>
658    
659            * Thuban/Model/proj.py (Projection.SetName): Set the name
660            to "Unknown" if name is None.
661            (Projection.SetAllParameters): New. Set the projection's
662            parameter list to the one supplied.
663            (Projection.SetProjection): New. Set the projection's
664            properties to those of the supplied Projection.
665    
666            * Thuban/UI/mainwindow.py (MainWindow.MapProjection): Set
667            the dialog title to include the map's title.
668            (MainWindow.LayerProjection): Set the dialog title to include
669            the layer's title.
670    
671            * Thuban/UI/projdialog.py (ProjFrame.__ShowError): Consolidate
672            error dialogs into a single method call.
673            (ProjFrame.__VerifyButtons): Add more states to check.
674            (ProjFrame.__GetProjection): Return the current state of an
675            edited projection or None.
676            (ProjFrame.__FillAvailList): Remove checks for states that
677            shouldn't exist.
678            (ProjFrame._OnNew): Clear all selected items and supply
679            a projection panel if necessary.
680    
681            * test/test_proj.py (TestProjFile.test): Add tests for
682            ProjFile.SetAllParameters, ProjFile.SetProjection,
683            ProjFile.SetName.
684    
685    2003-04-25  Jonathan Coles   <[email protected]>
686    
687            * Thuban/UI/projdialog.py (ProjFrame.__FillAvailList): Now
688            takes an optional argument to select the current projection.
689            This does not guarantee that the item is visible due to
690            limited wxWindows functionality. Fixes RTBug #1821.
691    
692    2003-04-25  Jonathan Coles   <[email protected]>
693    
694            * Thuban/Model/load.py (SessionLoader.start_projection): Remember
695            the projection name and use it when constructing the Projection
696            object.
697    
698            * Thuban/Model/proj.py (Projection.__init__): Change the default
699            value for 'name' to None and then test if name is equal to None
700            in the body of the constructor. This way the caller doesn't have to
701            know what the default value should be. Namely, useful in load.py
702            where we have to pick a default value if the 'name' parameter
703            doesn't exist in the XML file.
704    
705            * test/test_load.py (LoadSessionTest.testLayerProjection): New.
706            Tests a file where a layer has a projection.
707    
708    2003-04-25  Jonathan Coles   <[email protected]>
709    
710            * Thuban/Model/layer.py (Layer.TreeInfo): Add an item to the
711            tree for projection information.
712    
713            * Thuban/Model/load.py (XMLReader.GetFilename): Renamed from
714            XMLReader.GetFileName.
715            (SessionLoader): Added support for loading projection tags that
716            appear inside a layer.
717    
718            * Thuban/Model/proj.py (ProjFile): Document the class. Move
719            back to using a list because the order of the projections in
720            the file is important to maintain. Fixes RTbug #1817.
721    
722            * Thuban/Model/resource.py: Rename calls to ProjFile.GetFileName
723            to ProjFile.GetFilename.
724    
725            * Thuban/Model/save.py (SessionSaver.write_layer): Save projection
726            information.
727    
728            * Thuban/UI/projdialog.py (ProjFrame._OnAddToList): Renamed from
729            ProjFrame._OnSaveAs. Removed old dead code from previous
730            implementation.
731            (ProjFrame._OnExport): Add support for exporting more than one
732            projection to a single file.
733            (ProjFrame.__FillAvailList): use string formatting (% operator)
734            to build strings that are (partly) translated. Fixes RTbug #1818.
735    
736            * test/test_proj.py (TestProjFile.test): New. Tests the base ProjFile
737            class.
738    
739    2003-04-24  Bernhard Herzog  <[email protected]>
740    
741            * po/es.po: Updated Spanish translation by Daniel Calvelo Aros
742    
743            * po/fr.po: New. French translation by Daniel Calvelo Aros
744    
745            * Thuban/UI/projdialog.py (ProjFrame._OnSaveAs): Don't translate
746            empty strings.
747    
748    2003-04-24  Jonathan Coles   <[email protected]>
749    
750            * Thuban/Model/layer.py (Layer.GetProjection): New. Needed to
751            implement the interface that the ProjFrame dialog expects.
752    
753            * Thuban/Model/proj.py (Projection.SetName): New. Allows the
754            name of the projection to be changed.
755            (ProjFile): Use a dictionary instead of a list so that removing
756            projections is easier and we are sure about uniqueness.
757            (ProjFile.Remove): Remove the given projection object.
758    
759            * Thuban/Model/resource.py (GetSystemProjFiles, GetUserProjFiles):
760            Return a list with only one projection file instead of searching for
761            any projection file. This simplifies many things if the user can
762            only have one system file and one user file.
763    
764            * Thuban/UI/classgen.py: Change all references to
765            genCombo to genChoice.
766    
767            * Thuban/UI/mainwindow.py: Add a Projection option under the
768            layer menu.
769            (MainWindow.LayerProjection): New. Open up a projection window
770            for a layer.
771    
772            * Thuban/UI/projdialog.py: Large changes to how the dialog is
773            laid out. Use three panels instead of one. One for the list of
774            projections, one for the edit controls, and one for the buttons.
775            Fixed resizing problems so that the dialog resizes correctly
776            when the projection panel changes. Added import/export, save, and
777            new buttons/functionality.
778    
779    2003-04-24  Bernhard Herzog  <[email protected]>
780    
781            First step towards table management. Introduce a simple data
782            abstraction so that we replace the data a layer uses more easily
783            in the next step.
784    
785            * Thuban/Model/data.py: New file with a simple data abstraction
786            that bundles shapefile and dbffile into one object.
787    
788            * Thuban/Model/session.py (Session.OpenShapefile): New method to
789            open shapefiles and return a shape store object
790    
791            * Thuban/Model/layer.py (Layer.__init__): Pass the data as a store
792            object instead of a shapefile filename. This introduces a new
793            instance variable store holding the datastore. For intermediate

1180    
1181    2003-04-10  Jonathan Coles   <[email protected]>
1182    
1183            * Thuban/Model/classification.py: (ClassGroup): Move all the common
1184            methods of the derived classes ([Set|Get]Properties(), __eq__, __ne__)
1185            here. Implement SetVisible(), IsVisible().
1186            (ClassGroup.__init__): Add group parameter which acts as a copy
1187            constructor.
1188    
1189            * Thuban/UI/classifier.py (ClassTable): Add a new column for the
1190            "Visible" check boxes.

1192            the new labels.
1193    
1194            * Thuban/UI/legend.py: Classify button is now called "Properties".
1195            Refactored the code to change variable names.
1196            (LegendTree.__FillTreeLayer): Only list a group if it is visible.
1197    
1198            * Thuban/UI/mainwindow.py: MainWindow.OpenClassifier renamed to
1199            MainWindow.OpenLayerProperties. MainWindow.LayerEditProperties
1200            renamed to MainWindow.LayerEditProperties.
1201            (MainWindow.ToggleLegend): Don't include map name in legend title.
1202            (MainWindow.SetMap): Added the map name to the window title.
1203            (MainWindow.LayerFillColor, MainWindow.LayerTransparentFill,
1204            MainWindow.LayerOutlineColor, MainWindow.LayerNoOutline): Removed.
1205            Functionality is found in the layer properties dialog.
1206    
1207            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
1208            draw visible groups.
1209    
1210    2003-04-09  Jonathan Coles   <[email protected]>
1211    
1212            * Thuban/UI/classgen.py: Modifications to allow simple
1213            addition and selection of new color schemes.
1214            (MonochromaticRamp): New. Generates a ramp between two colors.
1215            (RedRamp): New. Generates a ramp of all red.
1216            (GreenRamp): New. Generates a ramp of all green.
1217            (BlueRamp): New. Generates a ramp of all blue.
1218    
1219    2003-04-09  Jonathan Coles   <[email protected]>
1220    
1221            * Thuban/Model/classification.py (Classification.__deepcopy__):
1222            Need to copy over field and fieldType attributes.
1223    
1224            * Thuban/Model/table.py (Table.field_range): New. Retrive the
1225            maximum and minimum values over the entire table for a given
1226            field.
1227            (Table.GetUniqueValues): New. Retrieve all the unique values
1228            in the table for a given field.
1229    
1230            * Thuban/UI/classgen.py: Renamed GenRangePanel to GenUniformPanel.
1231            (GenUniquePanel): New. Controls to allow the user to select
1232            which unique field values they would like in the classification.
1233            (CustomRampPanel): Code that was in ClassGenDialog that allows
1234            the user to select the properties for a custom ramp.
1235            (ClassGenerator.GenUniformDistribution): Was called GenerateRanges.
1236    
1237            * Thuban/UI/classifier.py: Removed a lot of debugging code.
1238            (Classifier._SetClassification): Callback method so that the
1239            class generator can set the classification in the grid.
1240            (ClassGroupPropertiesCtrl): New. Encapsulates the drawing and
1241            editing of a group properties class into a wxWindows control.
1242    
1243            * Thuban/UI/dock.py: It was decided that if the user closes
1244            a dockable window the window should simply hide itself. That
1245            way if the user wants to show the dock again it appears in the
1246            same place as it was when it was closed.
1247            (DockableWindow.Destroy): Call renamed method OnDockDestroy().
1248            (DockableWindow._OnButtonClose): Hide the window instead of

1250            (DockableWindow._OnClose): Hide the window instead of
1251            destroying it.
1252    
1253            * Thuban/UI/legend.py (LegendTree): Use a private method to

1257    
1258    2003-04-07  Bernhard Herzog  <[email protected]>
1259    
1260            * Thuban/UI/mainwindow.py (main_menu): Move the toggle_legend item
1261            to the map module
1262    
1263    2003-04-07  Bernhard Herzog  <[email protected]>
1264    
1265            * Thuban/UI/mainwindow.py (MainWindow.ShowSessionTree): Removed in
1266            favor of ToggleSessionTree
1267            (MainWindow.ToggleSessionTree): New method to toggle visibility of
1268            the session tree.
1269            (MainWindow.SessionTreeShown): New method to return whether the
1270            session tree is currently shown.
1271            (MainWindow.ToggleLegend): New method to toggle visibility of the
1272            legend
1273            (MainWindow.ShowLegend): Implement in terms of ToggleLegend and
1274            LegendShown
1275            (MainWindow.LegendShown): New method to return whether the legend
1276            is currently shown.
1277            (_method_command): Add checked parameter so we can define check
1278            menu items
1279            (_has_tree_window_shown, _has_legend_shown): Use the appropriate
1280            mainwindow methods.
1281            (show_session_tree, show_legend commands): Removed.
1282            (toggle_session_tree, toggle_legend commands): New commands to
1283            toggle the visibility of the dialogs
1284    
1285    2003-04-07  Jonathan Coles   <[email protected]>
1286    
1287            * Thuban/UI/classgen.py: Fix Windows problem.
1288    
1289            * Thuban/UI/dock.py: Fix Windows problem.
1290    
1291            * Thuban/UI/mainwindow.py: Use False instead of false.
1292            (MainWindow.ShowLegend): Remove unnecessary switch parameter.
1293    
1294    2003-04-07  Jonathan Coles   <[email protected]>
1295    
1296            Since we now say that the order of the groups in a classification
1297            matters, it makes sense to be able to manipulate that order. Most
1298            of the changes to Thuban/Model/classification.py are to that end.
1299    
1300            * Thuban/Model/classification.py (Classification.AppendGroup,
1301            Classification.InsertGroup, Classification.ReplaceGroup,
1302            Classification.RemoveGroup, Classification.GetGroup): Do as the
1303            names imply.
1304            (Classification.FindGroup): This was called GetGroup, but GetGroup
1305            takes an index, while FindGroup takes a value.
1306            (Classification.__deepcopy__): Copy all the groups, BUT NOT THE LAYER
1307            REFERENCE. Currently there is a cyclic reference between the layer
1308            and its classification. If the classification doesn't need to know
1309            its owning layer we can change this, since it may make sense to be
1310            able to use the same classification with different layers.
1311    
1312            * Thuban/Model/load.py: Use Classification.AppendGroup(), not AddGroup()
1313    
1314            * Thuban/UI/classgen.py: Use Classification.AppendGroup(),
1315            not AddGroup()
1316    
1317            * Thuban/UI/classifier.py: Now that we can depend on the order in
1318            a Classification and have methods to manipulate that order we don't
1319            need to use our own data structures in the grid. We can simply make
1320            the grid/table access the information they need from a copy of
1321            the classification object.
1322            (Classifier._OnCloseBtn): Event handler for when the user clicks
1323            'Close'. This is needed so if the user applies changes and then
1324            continues to change the table the user has the option of discarding
1325            the most recent changes and keeping what they applied.
1326    
1327            * Thuban/UI/mainwindow.py: Put "Show Legend" and "Show Session Tree"
1328            into the same group.
1329    
1330            * extensions/thuban/wxproj.cpp (check_version): If Thuban is compiled
1331            with a really old version of proj, PJ_VERSION won't even be defined.
1332            If it isn't defined then just compile so that the function always
1333            returns Py_False.
1334    
1335            * test/test_classification.py: Fix tests to use the renamed methods.
1336            Still need to write tests for the new methods.
1337    
1338    2003-04-04  Jonathan Coles   <[email protected]>
1339    
1340            * Thuban/UI/classifier.py (Classifier.__SelectField): Move the
1341            call to SetSelection out of the method and before the call
1342            to __SelectField in __init__. This prevents a recursion of events
1343            when _OnFieldSelect is triggered by the user.
1344    
1345    2003-04-04  Jonathan Coles   <[email protected]>
1346    
1347            * Thuban/Model/classification.py: Rename Color.None to
1348            Color.Transparent.
1349            (ClassGroupProperties.SetLineColori, ClassGroupProperties.SetFill):
1350            Don't bother copying the color, since Colors are immutable.
1351    
1352            * Thuban/Model/color.py, Thuban/Model/layer.py, Thuban/Model/load.py,
1353            Thuban/UI/classifier.py, Thuban/UI/mainwindow.py,
1354            Thuban/UI/renderer.py, Thuban/UI/view.py:
1355            Rename Color.None to Color.Transparent.
1356        
1357            * test/test_classification.py, test/test_load.py: Rename Color.None
1358            to Color.Transparent.
1359    
1360    2003-04-04  Jonathan Coles   <[email protected]>
1361    
1362            * Thuban/Model/classification.py: Fix assert calls.
1363            (ClassGroupProperties.SetLineColor, ClassGroupProperties.SetFill):
1364            Copy the color parameter rather than hold onto a reference.
1365    
1366            * Thuban/Model/color.py (Color.__copy__, Color.__deepcopy): Copy
1367            the color object.
1368            (NoColor.__copy__, NoColor.__deepcopy): Return 'self' so that we
1369            are sure there exists only one refernce to Color.None in the system.
1370            This allows us to use 'is' rather than the comparision functions.
1371            
1372            * Thuban/Model/save.py: Fix assert calls.
1373            
1374            * Thuban/UI/classifier.py: Fix assert calls.
1375            (ClassGrid._OnCellDClick): Call up to the classifier to open the
1376            dialog to edit the groups properties.
1377            (ClassGrid._OnCellResize): Make sure that the scollbars are drawn
1378            correctly if a cell is resized.
1379            (ClassTable.SetClassification): New. Changes the classification
1380            that is in the table.
1381            (ClassTable.__SetRow): Allow groups to be prepended.
1382            (Classifier): New code for opening the EditProperties and
1383            GenerateRanges dialogs.
1384            (SelectPropertiesDialog.__GetColor): Only set the color in the
1385            color dialog if the current color is not None.
1386            
1387            * Thuban/UI/dock.py: Fix assert calls.
1388            
1389            * Thuban/UI/legend.py: Fix assert calls.
1390            
1391            * Thuban/UI/renderer.py: Fix assert calls.
1392            
1393            * Thuban/UI/classgen.py (ClassGenDialog): Dialog for generating
1394            classifications.
1395            (GenRangePanel): Panel specific to range generation.
1396            (GenSingletonPanel): Panel specific to singleton generation.
1397            (ClassGenerator): Class responsible for actually generating
1398            the classification from the data gathered in the dialog box.
1399            (PropertyRamp): Generates properties whose values range from
1400            a starting property to an ending property.
1401    
1402    2003-04-03  Bernhard Herzog  <[email protected]>
1403    
1404            * test/support.py (print_garbage_information): New function that
1405            prints information about still connected messages and memory
1406            leaks.
1407            (run_suite): Removed.
1408            (run_tests): New function for use as a replacement of
1409            unittest.main in the test_* files. This one calls
1410            print_garbage_information at the end.
1411    
1412            * test/runtests.py (main): Use support.print_garbage_information
1413    
1414            * test/test_layer.py: Use support.run_tests instead of
1415            unittest.main so we get memory leak information
1416            (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
1417            (TestLayer.test_point_layer, TestLayer.test_empty_layer)
1418            (TestLayerLegend.test_visibility): Call the layer's Destroy method
1419            to fix a memory leak.
1420    
1421            * test/test_classification.py: Use support.run_tests instead of
1422            unittest.main so we get memory leak information
1423            (TestClassification.test_classification): Call the layer's Destroy
1424            method to fix a memory leak.
1425    
1426    2003-04-02  Bernhard Herzog  <[email protected]>
1427    
1428            * extensions/thuban/wxproj.cpp (check_version, check_version_gtk):
1429            Handle the reference counts of the return value and errors in
1430            PyArg_ParseTuple correctly.
1431    
1432            * Thuban/UI/application.py (ThubanApplication.OpenSession): Make
1433            sure the filename is absolute to avoid problems when saving the
1434            session again
1435    
1436            * Thuban/Model/table.py: Remove unnecessary import. Fix a typo.
1437    
1438    2003-04-01  Jonathan Coles   <[email protected]>
1439    
1440            *  Thuban/UI/renderer.py (MapRenderer.draw_point_shape): Check
1441            that there actually are points in the returned list of points
1442            before trying to index into the list. The list may be empty if
1443            the shape is a Null Shape.
1444    
1445    2003-04-01  Bernhard Herzog  <[email protected]>
1446    
1447            * test/test_map.py: Don't use from <module> import *
1448    
1449    2003-04-01  Jonathan Coles   <[email protected]>
1450    
1451            * Thuban/Model/session.py: Use LAYER_CHANGED instead of
1452            LAYER_LEGEND_CHANGED
1453    
1454            * Thuban/UI/dock.py (DockableWindow._OnButtonClose): Call
1455            self.Destroy() to close the window after yesterday's changes.
1456    
1457            * test/test_map.py, test/test_session.py: Fix messages that
1458            are sent from maps and layers.
1459

1464            RTbug #1769.
1465    
1466            * Thuban/UI/dock.py (DockableWindow.UnDock): Restore size and
1467            position (although position doesn't work yet under GTK).
1468            (DockableWindow.Destroy): New. Called when the window must be
1469            closed. Namely needed when the DockFrame closes and must close
1470            its children.

1472    
1473            * Thuban/UI/legend.py (LegendPanel.Destroy): New. Cleans up
1474            when then window is told to close.
1475            (LegendTree._OnMsgLayerChanged): Fixes a seg fault bug. See
1476            comment in source for more info.

1478            * Thuban/UI/main.py: Show the legend by default when Thuban starts.
1479    
1480            * Thuban/UI/mainwindow.py: Renamed OnClose to _OnClose for
1481            symmetry with other such methods.
1482            (MainWindow.ShowLegend): Show the legend docked by default.
1483    
1484    2003-03-28  Jonathan Coles   <[email protected]>
1485    
1486            * Thuban/UI/classifier.py: Support for highlighting a specific
1487            group within the grid when the classification dialog is opened.
1488            Also contains a lot of debugging printouts which will later
1489            be removed.
1490    
1491            * Thuban/UI/dock.py: Complete rework on the dock code so that
1492            that it is fairly removed from the rest of the Thuban application.
1493            It is easy to add new docks which the rest of the program having
1494            to be aware of them.
1495    
1496            * Thuban/UI/legend.py: Modifications to support selecting a
1497            specific group in the classification dialog. Changed how layers
1498            are drawn when the layer is visible/invisible.
1499    
1500            * Thuban/UI/mainwindow.py: Removed legend specific code and
1501            replaced it with calls to the new dock code.
1502    
1503            * Thuban/UI/renderer.py (MapRenderer.__init__): Added assert
1504            to check if scale > 0. Trying to track down a divide by zero.
1505    
1506    2003-03-26  Jonathan Coles   <[email protected]>
1507    
1508            * Thuban/UI/legend.py: Removed unnecessary LegendDialog class.
1509            (LegendPanel): Removed _OnDock()/_OnUnDock() methods which are
1510            now part of DockableWindow.

1513            (LegendTree._OnSelChanged): Call LegendPanel.DoOnSelChanged()
1514            with the selected layer and/or group.
1515    
1516    2003-03-26  Jonathan Coles   <[email protected]>
1517    
1518            This putback contains the code for dockable windows. There is
1519            no support in wxWindows as of this date for windows that can
1520            attach themselves to other windows.
1521    
1522            The current model contains a DockableWindow which has a parent
1523            window for when it is detached and a dock window that it puts
1524            its contents in when it is docked. The contents of a DockableWindow
1525            must be a DockPanel. DockPanel itself derives from wxPanel.
1526    
1527            * Thuban/Model/layer.py (Layer.ClassChanged): Send a LAYER_CHANGED
1528            message, not a LAYER_LEGEND_CHANGED message.
1529    
1530            * Thuban/Model/map.py (Map): Forward LAYER_CHANGED messages.
1531    
1532            * Thuban/UI/classifier.py (Classifier.__init__): Use wxADJUST_MINSIZE
1533            as one of the style properties for the fieldTypeText item to
1534            be sure that its size is correct when the text changes.
1535    
1536            * Thuban/UI/dock.py: New. Classes for the DockPanel and
1537            DockableWindow.
1538    
1539            * Thuban/UI/legend.py: Added some more buttons and made the
1540            LegendPanel a DockPanel.
1541    
1542            * Thuban/UI/mainwindow.py: Added sash windows to the main window
1543            and supporting functions for manipulating the sashes.
1544            (MainWindow.ShowLegend): Create a DockableWindow with the
1545            LegendPanel as the contents.
1546    
1547            * Thuban/UI/messages.py: Added DOCKABLE_* messages
1548    
1549            * Thuban/UI/view.py (MapCanves.SetMap): Listen for LAYER_CHANGED,
1550            not LAYER_LEGEND_CHANGED, messages.

1554            * setup.py: Added custom script bdist_rpm_build_script so that

1556    
1557            * setup.cfg: Added line saying to use the custom build script

1560    
1561            Initial implementation of the Legend.
1562    
1563            * Thuban/UI/legend.py: New. Creates a window that shows the map's
1564            Legend information and allows the user to add/modify classifications
1565            and how the layers are drawn on the map.
1566    
1567            * setup.py: New command 'build_docs' which currently uses
1568            happydoc to generate html documentation for Thuban.
1569    
1570            * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
1571            Returns a string which is appropriately describes the group.
1572    
1573            * Thuban/Model/layer.py (Layer.SetClassification): Generate a
1574            LAYER_CHANGED event instead of a LAYER_LEGEND_CHANGED event.
1575    
1576            * Thuban/Model/map.py (Map): Rename messages and use new, more
1577            specific, messages.
1578    
1579            * Thuban/Model/messages.py: New message to indicate that a layer's
1580            data has changed (LAYER_CHANGED). New map messages to indicate
1581            when layers have been added/removed/changed or if the stacking order
1582            of the layers has changed.
1583    
1584            * Thuban/Model/session.py: Rename and use new messages.
1585    
1586            * Thuban/UI/classifier.py: Remember if any changes have actually
1587            been applied so that if the dialog is cancelled without an application
1588            of changes we don't have to set a new classification.
1589            (ClassDataPreviewer): Pulled out the window specific code and put it
1590            ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
1591            symbols on any DC.
1592            
1593            * Thuban/UI/mainwindow.py: New code to open the legend.
1594    
1595            * Thuban/UI/view.py: Use new message names.

1597    2003-03-19  Jonathan Coles   <[email protected]>
1598    
1599            * Thuban/UI/main.py (verify_versions): New. Checks the versions
1600            of Python, wxPython, and some other libraries.
1601    
1602            * extensions/thuban/wxproj.cpp (check_version): Checks the given
1603            version against what wxproj was compiled with.
1604            (check_version_gtk): If wxproj was compiled with gtk then check
1605            the given version against the version of the gtk library
1606            currently being used.
