14    
15            * Thuban/Model/load.py (XMLReader): Renamed from XMLProcessor to
16            promote symmetry. There now exists XMLReader and XMLWriter.
17            (XMLReader.read): New. Call to read the given file descriptor or
18            filename.
19            (XMLReader.close): New. Make sure the file is closed.

31            (SessionLoader.__init__): Add dispatcher functions.
32            (load_xmlfile): Code was moved into the XMLReader.read().
33            (load_session): Use modified SessionLoader.

35            * Thuban/Model/map.py (Map.GetProjection): New. Returns the
36            map's projection.
37

55            control instead of a wxComboBox. wxChoice controls do not generate
56            events as the uses highlights possible choices which fixes problems
57            with resizing the dialog when the use selects an option.
58    
59            * Thuban/UI/classifier.py (Classifier.__init__): Use a wxChoice
60            control instead of a wxComboBox.

82            (Layer.ShapeType, Layer.Shape): No need to call
83            self.open_shapefile since it's always called in __init__
84    
85            * Thuban/UI/application.py (ThubanApplication.MainLoop): Removed.
86            In wxPython 2.4 there's no need to extend MainLoop anymore since

121            * test/test_load.py: Rework the classification test to test
122            that we can load old files.

135            handling of these low-level parameters so that each s_draw_info
136            instance is handled as a CObject at python level that also
137            contains real references to the actual python objects which
138            contain the values in the struct. Add free_draw_info as the
139            destructor.

395    
396            * Thuban/UI/mainwindow.py (MainWindow.ShowSessionTree): Removed in
397            favor of ToggleSessionTree
398            (MainWindow.ToggleSessionTree): New method to toggle visibility of
399            the session tree.
400            (MainWindow.SessionTreeShown): New method to return whether the
401            session tree is currently shown.
402            (MainWindow.ToggleLegend): New method to toggle visibility of the
403            legend
404            (MainWindow.ShowLegend): Implement in terms of ToggleLegend and
405            LegendShown
406            (MainWindow.LegendShown): New method to return whether the legend
407            is currently shown.
408            (_method_command): Add checked parameter so we can define check
409            menu items
410            (_has_tree_window_shown, _has_legend_shown): Use the appropriate
411            mainwindow methods.
412            (show_session_tree, show_legend commands): Removed.
413            (toggle_session_tree, toggle_legend commands): New commands to
414            toggle the visibility of the dialogs
415    
416    2003-04-07  Jonathan Coles   <[email protected]>
417    
418            * Thuban/UI/classgen.py: Fix Windows problem.
419    
420            * Thuban/UI/dock.py: Fix Windows problem.
421    
422            * Thuban/UI/mainwindow.py: Use False instead of false.
423            (MainWindow.ShowLegend): Remove unnecessary switch parameter.
424    
425    2003-04-07  Jonathan Coles   <[email protected]>
426    
427            Since we now say that the order of the groups in a classification
428            matters, it makes sense to be able to manipulate that order. Most
429            of the changes to Thuban/Model/classification.py are to that end.
430    
431            * Thuban/Model/classification.py (Classification.AppendGroup,
432            Classification.InsertGroup, Classification.ReplaceGroup,
433            Classification.RemoveGroup, Classification.GetGroup): Do as the
434            names imply.
435            (Classification.FindGroup): This was called GetGroup, but GetGroup
436            takes an index, while FindGroup takes a value.
437            (Classification.__deepcopy__): Copy all the groups, BUT NOT THE LAYER
438            REFERENCE. Currently there is a cyclic reference between the layer
439            and its classification. If the classification doesn't need to know
440            its owning layer we can change this, since it may make sense to be
441            able to use the same classification with different layers.
442    
443            * Thuban/Model/load.py: Use Classification.AppendGroup(), not AddGroup()
444    
445            * Thuban/UI/classgen.py: Use Classification.AppendGroup(),
446            not AddGroup()
447    
448            * Thuban/UI/classifier.py: Now that we can depend on the order in
449            a Classification and have methods to manipulate that order we don't
450            need to use our own data structures in the grid. We can simply make
451            the grid/table access the information they need from a copy of
452            the classification object.
453            (Classifier._OnCloseBtn): Event handler for when the user clicks
454            'Close'. This is needed so if the user applies changes and then
455            continues to change the table the user has the option of discarding
456            the most recent changes and keeping what they applied.
457    
458            * Thuban/UI/mainwindow.py: Put "Show Legend" and "Show Session Tree"
459            into the same group.
460    
461            * extensions/thuban/wxproj.cpp (check_version): If Thuban is compiled
462            with a really old version of proj, PJ_VERSION won't even be defined.
463            If it isn't defined then just compile so that the function always
464            returns Py_False.
465    
466            * test/test_classification.py: Fix tests to use the renamed methods.
467            Still need to write tests for the new methods.
468    
469    2003-04-04  Jonathan Coles   <[email protected]>
470    
471            * Thuban/UI/classifier.py (Classifier.__SelectField): Move the
472            call to SetSelection out of the method and before the call
473            to __SelectField in __init__. This prevents a recursion of events
474            when _OnFieldSelect is triggered by the user.
475    
476    2003-04-04  Jonathan Coles   <[email protected]>
477    
478            * Thuban/Model/classification.py: Rename Color.None to
479            Color.Transparent.
480            (ClassGroupProperties.SetLineColori, ClassGroupProperties.SetFill):
481            Don't bother copying the color, since Colors are immutable.
482    
483            * Thuban/Model/color.py, Thuban/Model/layer.py, Thuban/Model/load.py,
484            Thuban/UI/classifier.py, Thuban/UI/mainwindow.py,
485            Thuban/UI/renderer.py, Thuban/UI/view.py:
486            Rename Color.None to Color.Transparent.
487        
488            * test/test_classification.py, test/test_load.py: Rename Color.None
489            to Color.Transparent.
490    
491    2003-04-04  Jonathan Coles   <[email protected]>
492    
493            * Thuban/Model/classification.py: Fix assert calls.
494            (ClassGroupProperties.SetLineColor, ClassGroupProperties.SetFill):
495            Copy the color parameter rather than hold onto a reference.
496    
497            * Thuban/Model/color.py (Color.__copy__, Color.__deepcopy): Copy
498            the color object.
499            (NoColor.__copy__, NoColor.__deepcopy): Return 'self' so that we
500            are sure there exists only one refernce to Color.None in the system.
501            This allows us to use 'is' rather than the comparision functions.
502            
503            * Thuban/Model/save.py: Fix assert calls.
504            
505            * Thuban/UI/classifier.py: Fix assert calls.
506            (ClassGrid._OnCellDClick): Call up to the classifier to open the
507            dialog to edit the groups properties.
508            (ClassGrid._OnCellResize): Make sure that the scollbars are drawn
509            correctly if a cell is resized.
510            (ClassTable.SetClassification): New. Changes the classification
511            that is in the table.
512            (ClassTable.__SetRow): Allow groups to be prepended.
513            (Classifier): New code for opening the EditProperties and
514            GenerateRanges dialogs.
515            (SelectPropertiesDialog.__GetColor): Only set the color in the
516            color dialog if the current color is not None.
517            
518            * Thuban/UI/dock.py: Fix assert calls.
519            
520            * Thuban/UI/legend.py: Fix assert calls.
521            
522            * Thuban/UI/renderer.py: Fix assert calls.
523            
524            * Thuban/UI/classgen.py (ClassGenDialog): Dialog for generating
525            classifications.
526            (GenRangePanel): Panel specific to range generation.
527            (GenSingletonPanel): Panel specific to singleton generation.
528            (ClassGenerator): Class responsible for actually generating
529            the classification from the data gathered in the dialog box.
530            (PropertyRamp): Generates properties whose values range from
531            a starting property to an ending property.
532    
533    2003-04-03  Bernhard Herzog  <[email protected]>
534    
535            * test/support.py (print_garbage_information): New function that
536            prints information about still connected messages and memory
537            leaks.
538            (run_suite): Removed.
539            (run_tests): New function for use as a replacement of
540            unittest.main in the test_* files. This one calls
541            print_garbage_information at the end.
542    
543            * test/runtests.py (main): Use support.print_garbage_information
544    
545            * test/test_layer.py: Use support.run_tests instead of
546            unittest.main so we get memory leak information
547            (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
548            (TestLayer.test_point_layer, TestLayer.test_empty_layer)
549            (TestLayerLegend.test_visibility): Call the layer's Destroy method
550            to fix a memory leak.
551    
552            * test/test_classification.py: Use support.run_tests instead of
553            unittest.main so we get memory leak information
554            (TestClassification.test_classification): Call the layer's Destroy
555            method to fix a memory leak.
556    
557    2003-04-02  Bernhard Herzog  <[email protected]>
558    
559            * extensions/thuban/wxproj.cpp (check_version, check_version_gtk):
560            Handle the reference counts of the return value and errors in
561            PyArg_ParseTuple correctly.
562    
563            * Thuban/UI/application.py (ThubanApplication.OpenSession): Make
564            sure the filename is absolute to avoid problems when saving the
565            session again
566    
567            * Thuban/Model/table.py: Remove unnecessary import. Fix a typo.
568    
569    2003-04-01  Jonathan Coles   <[email protected]>
570    
571            *  Thuban/UI/renderer.py (MapRenderer.draw_point_shape): Check
572            that there actually are points in the returned list of points
573            before trying to index into the list. The list may be empty if
574            the shape is a Null Shape.
575    
576    2003-04-01  Bernhard Herzog  <[email protected]>
577    
578            * test/test_map.py: Don't use from <module> import *
579    
580    2003-04-01  Jonathan Coles   <[email protected]>
581    
582            * Thuban/Model/session.py: Use LAYER_CHANGED instead of
583            LAYER_LEGEND_CHANGED
584    
585            * Thuban/UI/dock.py (DockableWindow._OnButtonClose): Call
586            self.Destroy() to close the window after yesterday's changes.
587    
588            * test/test_map.py, test/test_session.py: Fix messages that
589            are sent from maps and layers.
590

593            * Thuban/UI/classifier.py: Commented out some debugging statements.
594            (ClassDataPreviewer.Draw): Draw rectangles for polygon layers per
595            RTbug #1769.
596    
597            * Thuban/UI/dock.py (DockableWindow.UnDock): Restore size and
598            position (although position doesn't work yet under GTK).
599            (DockableWindow.Destroy): New. Called when the window must be
600            closed. Namely needed when the DockFrame closes and must close
601            its children.
602            (DockFrame): Listen for EVT_CLOSE and destroy all children.
603    
604            * Thuban/UI/legend.py (LegendPanel.Destroy): New. Cleans up
605            when then window is told to close.
606            (LegendTree._OnMsgLayerChanged): Fixes a seg fault bug. See
607            comment in source for more info.
608    
609            * Thuban/UI/main.py: Show the legend by default when Thuban starts.
610    
611            * Thuban/UI/mainwindow.py: Renamed OnClose to _OnClose for
612            symmetry with other such methods.
613            (MainWindow.ShowLegend): Show the legend docked by default.
614    
615    2003-03-28  Jonathan Coles   <[email protected]>
616    
617            * Thuban/UI/classifier.py: Support for highlighting a specific
618            group within the grid when the classification dialog is opened.
619            Also contains a lot of debugging printouts which will later
620            be removed.
621    
622            * Thuban/UI/dock.py: Complete rework on the dock code so that
623            that it is fairly removed from the rest of the Thuban application.
624            It is easy to add new docks which the rest of the program having
625            to be aware of them.
626    
627            * Thuban/UI/legend.py: Modifications to support selecting a
628            specific group in the classification dialog. Changed how layers
629            are drawn when the layer is visible/invisible.
630    
631            * Thuban/UI/mainwindow.py: Removed legend specific code and
632            replaced it with calls to the new dock code.
633    
634            * Thuban/UI/renderer.py (MapRenderer.__init__): Added assert
635            to check if scale > 0. Trying to track down a divide by zero.
636    
637    2003-03-26  Jonathan Coles   <[email protected]>
638    
639            * Thuban/UI/legend.py: Removed unnecessary LegendDialog class.
640            (LegendPanel): Removed _OnDock()/_OnUnDock() methods which are
641            now part of DockableWindow.
642            (LegendPanel.DoOnSelChanged): Select the current layer in the
643            map.
644            (LegendTree._OnSelChanged): Call LegendPanel.DoOnSelChanged()
645            with the selected layer and/or group.
646    
647    2003-03-26  Jonathan Coles   <[email protected]>
648    
649            This putback contains the code for dockable windows. There is
650            no support in wxWindows as of this date for windows that can
651            attach themselves to other windows.
652    
653            The current model contains a DockableWindow which has a parent
654            window for when it is detached and a dock window that it puts
655            its contents in when it is docked. The contents of a DockableWindow
656            must be a DockPanel. DockPanel itself derives from wxPanel.
657    
658            * Thuban/Model/layer.py (Layer.ClassChanged): Send a LAYER_CHANGED
659            message, not a LAYER_LEGEND_CHANGED message.
660    
661            * Thuban/Model/map.py (Map): Forward LAYER_CHANGED messages.
662    
663            * Thuban/UI/classifier.py (Classifier.__init__): Use wxADJUST_MINSIZE
664            as one of the style properties for the fieldTypeText item to
665            be sure that its size is correct when the text changes.
666    
667            * Thuban/UI/dock.py: New. Classes for the DockPanel and
668            DockableWindow.
669    
670            * Thuban/UI/legend.py: Added some more buttons and made the
671            LegendPanel a DockPanel.
672    
673            * Thuban/UI/mainwindow.py: Added sash windows to the main window
674            and supporting functions for manipulating the sashes.
675            (MainWindow.ShowLegend): Create a DockableWindow with the
676            LegendPanel as the contents.
677    
678            * Thuban/UI/messages.py: Added DOCKABLE_* messages
679    
680            * Thuban/UI/view.py (MapCanves.SetMap): Listen for LAYER_CHANGED,
681            not LAYER_LEGEND_CHANGED, messages.
682    
683    2003-03-25  Jonathan Coles   <[email protected]>
684    
685            * setup.py: Added custom script bdist_rpm_build_script so that
686            when the rpm is built the path to wx-config is correct.
687    
688            * setup.cfg: Added line saying to use the custom build script
689    
690    2003-03-20  Jonathan Coles   <[email protected]>
691    
692            Initial implementation of the Legend.
693    
694            * Thuban/UI/legend.py: New. Creates a window that shows the map's
695            Legend information and allows the user to add/modify classifications
696            and how the layers are drawn on the map.
697    
698            * setup.py: New command 'build_docs' which currently uses
699            happydoc to generate html documentation for Thuban.
700    
701            * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
702            Returns a string which is appropriately describes the group.
703    
704            * Thuban/Model/layer.py (Layer.SetClassification): Generate a
705            LAYER_CHANGED event instead of a LAYER_LEGEND_CHANGED event.
706    
707            * Thuban/Model/map.py (Map): Rename messages and use new, more
708            specific, messages.
709    
710            * Thuban/Model/messages.py: New message to indicate that a layer's
711            data has changed (LAYER_CHANGED). New map messages to indicate
712            when layers have been added/removed/changed or if the stacking order
713            of the layers has changed.
714    
715            * Thuban/Model/session.py: Rename and use new messages.
716    
717            * Thuban/UI/classifier.py: Remember if any changes have actually
718            been applied so that if the dialog is cancelled without an application
719            of changes we don't have to set a new classification.
720            (ClassDataPreviewer): Pulled out the window specific code and put it
721            ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
722            symbols on any DC.
723            
724            * Thuban/UI/mainwindow.py: New code to open the legend.
725    
726            * Thuban/UI/view.py: Use new message names.
727    
728    2003-03-19  Jonathan Coles   <[email protected]>
729    
730            * Thuban/UI/main.py (verify_versions): New. Checks the versions
731            of Python, wxPython, and some other libraries.
732    
733            * extensions/thuban/wxproj.cpp (check_version): Checks the given
734            version against what wxproj was compiled with.
735            (check_version_gtk): If wxproj was compiled with gtk then check
736            the given version against the version of the gtk library
737            currently being used.
738    
739    2003-03-14  Bernhard Herzog  <[email protected]>
740    
741            * test/test_command.py: Run the tests when the module is run as a
742            script
743    
744    2003-03-14  Bernhard Herzog  <[email protected]>
745    
746            Implement selection of multiple selected shapes in the same layer:
747    
748            - Introduce a new class to hold the selection. This basically
749              replaces the interactor which was nothing more than the
750              selection anyway. A major difference is of course that the new
751              selection class supports multiple selected shapes in one layer
752            
753            - Move the object that represents the selection from the
754              application to the canvas. The canvas is a better place than the
755              application because the selection represents which shapes and
756              layer of the map displayed by the canvas are selected and
757              affects how the map is drawn.
758    
759            - Make the selection and its messages publicly available through
760              the mainwindow.
761    
762            - The non-modal dialogs do not get a reference to the interactor
763              anymore as they can simply refer to their parent, the
764              mainwindow, for the what the interactor had to offer.
765    
766            * Thuban/UI/selection.py: New module with a class to represent the
767            selection.
768    
769            * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
770            these unused messages
771    
772            * Thuban/UI/application.py (ThubanApplication.OnInit)
773            (ThubanApplication.OnExit, ThubanApplication.SetSession): The
774            interactor is gone now.
775            (ThubanApplication.CreateMainWindow): There is no interactor
776            anymore so we pass None as the interactor argument for now for
777            compatibility.
778    
779            * Thuban/UI/view.py (MapCanvas.delegated_messages)
780            (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
781            Unsubscribe, delegate messages according to the delegated_messages
782            class variable.
783            (MapCanvas.__getattr__, MapCanvas.delegated_methods): Get some
784            attributes from instance variables as described with the
785            delegated_methods class variable.
786            (MapCanvas.__init__): New instance variable selection holding the
787            current selection
788            (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
789            pass them on to the renderer
790            (MapCanvas.SetMap): Clear the selection when a different map is
791            selected.
792            (MapCanvas.shape_selected): Simple force a complete redraw. The
793            selection class now takes care of only issueing SHAPES_SELECTED
794            messages when the set of selected shapes actually does change.
795            (MapCanvas.SelectShapeAt): The selection is now managed in
796            self.selection
797    
798            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
799            (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
800            Unsubscribe, delegate messages according to the delegated_messages
801            class variable.
802            (MainWindow.delegated_methods, MainWindow.__getattr__): Get some
803            attributes from instance variables as described with the
804            delegated_methods class variable.
805            (MainWindow.__init__): The interactor as ivar is gone. The
806            parameter is still there for compatibility. The selection messages
807            now come from the canvas.
808            (MainWindow.current_layer, MainWindow.has_selected_layer):
809            Delegate to the the canvas.
810            (MainWindow.LayerShowTable, MainWindow.Classify)
811            (MainWindow.identify_view_on_demand): The dialogs don't need the
812            interactor parameter anymore.
813    
814            * Thuban/UI/tableview.py (TableFrame.__init__)
815            (LayerTableFrame.__init__, LayerTableFrame.OnClose)
816            (LayerTableFrame.row_selected): The interactor is gone. It's job
817            from the dialog's point of view is now done by the mainwindow,
818            i.e. the parent. Subscribe to SHAPES_SELECTED instead
819            of SELECTED_SHAPE
820            
821            * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
822            is gone. It's job from the dialog's point of view is now done by
823            the mainwindow, i.e. the parent.
824            
825            * Thuban/UI/classifier.py (Classifier.__init__): The interactor is
826            gone. It's job from the dialog's point of view is now done by the
827            mainwindow, i.e. the parent.
828    
829            * Thuban/UI/tree.py (SessionTreeView.__init__): The interactor is
830            gone. It's job from the dialog's point of view is now done by the
831            mainwindow, i.e. the parent.
832            (SessionTreeCtrl.__init__): New parameter mainwindow which is
833            stored as self.mainwindow. The mainwindow is need so that the tree
834            can still subscribe to the selection messages.
835            (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
836            (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
837            selection is now accessible through the mainwindow. Subscribe to
838            SHAPES_SELECTED instead of SELECTED_SHAPE
839    
840            * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
841            SHAPES_SELECTED message now.
842            (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
843            so deal with multiple shapes
844            (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
845            gone. It's job from the dialog's point of view is now done by the
846            mainwindow, i.e. the parent.
847    
848            * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
849            parameter is now a list of shape ids.
850            (RecordTable.SetTable): The second parameter is now a list of
851            indices.
852    
853            * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the
854            selected_shape parameter and ivar to selected_shapes. It's now a
855            list of shape ids.
856            (MapRenderer.draw_label_layer): Deal with multiple selected
857            shapes. Rearrange the code a bit so that the setup and shape type
858            distinctions are only executed once.
859    
860            * test/test_selection.py: Test cases for the selection class
861    
862    2003-03-11  Jonathan Coles   <[email protected]>
863    
864            * Thuban/Model/load.py: Temporary fix so that the xml reader
865            doesn't cause Thuban to crash.
866    
867            * Thuban/Model/layer.py: Handle the cyclic references between
868            a layer and its classification better, and be sure to disconnect
869            the classification from the layer when the layer is destroyed
870            so that we don't maintain a cyclic reference that may not be
871            garbage collected.
872    
873            * Thuban/Model/classification.py: See comment for layer.py.
874    
875    2003-03-12  Jan-Oliver Wagner <[email protected]>
876    
877            * HOWTO-Release: New. Information on the steps for releasing
878            a new version of Thuban.
879    
880    2003-03-11  Jonathan Coles   <[email protected]>
881    
882            * Thuban/UI/classifier.py: Add normal border to SelectPropertiesDialog.
883            Use True instead of true.
884            (Classifier): Should have a single panel in which all the controls lie.
885    
886            * Thuban/UI/proj4dialog.py: Add normal border.
887    
888            * Thuban/UI/tree.py: Fixed problem with bad item images under Windows.
889    
890            * Thuban/UI/mainwindow.py: Use True instead of true.
891    
892            * setup.py: Update some definitions to use wxWindows2.4 files
893    
894            * Data/iceland_sample_class.thuban: Fixed file so that the
895            field_type information is present.
896    
897    2003-03-10  Jonathan Coles   <[email protected]>
898    
899            * Thuban/UI/classifier.py (Classifier.__init__): Make the
900            field type label grow so that when the text changes the
901            size is updated correctly. This may be a wxWindows bug.
902    
903    2003-03-10  Jonathan Coles   <[email protected]>
904    
905            * Thuban/UI/application.py: Changed SESSION_CHANGED to
906            SESSION_REPLACED.
907    
908            * Thuban/UI/classifier.py: Wrap text with _().
909            (ClassGrid.CreateTable): Set dimensions and size hints here,
910            instead of in Reset, so we only set the size once.
911    
912            * Thuban/UI/dialogs.py: Don't need Shutdown(); just use Close()!
913    
914            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
915            Call Close() instead of Shutdown().
916    
917            * Thuban/UI/messages.py: Changed SESSION_CHANGED to SESSION_REPLACED.
918    
919            * Thuban/UI/tree.py: Changed SESSION_CHANGED to SESSION_REPLACED.
920            Go back to using OnClose() instead of Shutdown().
921    
922    2003-03-10  Jonathan Coles   <[email protected]>
923    
924            * Thuban/UI/classifier.py (Classifier): SelectField() needed
925            to know the old field index as well as the new one.
926    
927    2003-03-10  Jonathan Coles   <[email protected]>
928    
929            * Thuban/UI/classifier.py (Classifier): Use __SelectField()
930            to correctly set the table information and call this from
931            __init__ and from _OnFieldSelect so that all the information
932            is up to date when the dialog opens and when a field is changed.
933    
934    2003-03-10  Jonathan Coles   <[email protected]>
935    
936            * Thuban/Model/classification.py (Classification): Don't use
937            layer's message function directly, use the ClassChanged() method
938            when then classification changes. SetField/SetFieldType/SetLayer
939            must keep the information about field name and field type in
940            sync when an owning layer is set or removed.
941    
942            * Thuban/Model/layer.py: Added ClassChanged() so that the
943            classification can tell the layer when its data has changed.
944            (Layer.SetClassification): Accepts None as an arguement to
945            remove the current classification and correctly handles
946            adding a new classification.
947    
948            * Thuban/Model/load.py: Comment out print statement
949    
950            * test/test_classification.py, test/test_save.py: New and
951            improved tests.
952    
953    2003-03-07  Jonathan Coles   <[email protected]>
954    
955            * Thuban/Model/classification.py: Implemented __copy__ and
956            __deepcopy__ for ClassGroup* and ClassGroupProperites so
957            they can easily be copied by the classifier dialog.
958            (ClassGroupProperites.__init__): The default line color should
959            have been Color.Black.
960    
961            * Thuban/UI/classifier.py: Setting and Getting table values now
962            uses a consistent set of functions.
963            (Classifier): Now non-modal. Has field type label which changes
964            as the field changes. Keep track of buttons in a list so that
965            we can enable/disable the buttons when the None field is selected.
966            (SelectPropertiesDialog): Add buttons to make the colors transparent.
967    
968            * Thuban/UI/dialogs.py (NonModalDialog.Shutdown): New method which
969            does what OnClose did, but can be called by the application to
970            close a window. Needed when a session changes, and we have to
971            close the classifier windows.
972    
973            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
974            Shuts down open dialogs. Used when a new session is created
975            or a session is opened.
976            (MainWindow.SaveSession): Should only call application.SaveSession()
977            if we don't call SaveSessionAs first.
978            (MainWindow.Classify): Allow different classifier dialogs for
979            different layers.
980    
981            * Thuban/UI/tree.py (SessionTreeView): Remove OnClose and let
982            the parent class handle it. Add Shutdown() to unsubscibe from
983            event notification and call the parent Shutdown(). This was
984            necessary so the application can close the tree window.
985    
986    2003-03-06  Jonathan Coles   <[email protected]>
987    
988            * Thuban/Model/classification.py: Minor documentation changes,
989            Addition of __eq__ and __ne__ methods.
990            (Classification.SetLayer): prevent recursion between this method
991            and Layer.SetClassification().
992    
993            * Thuban/Model/color.py: Addition of __eq__ and __ne__ methods.
994    
995            * Thuban/Model/layer.py (SetClassification): prevent recursion
996            between this method and Classification.SetLayer().
997    
998            * test/test_classification.py, test/test_load.py,
999            test/test_session.py: Fixed and added tests for the classification
1000            classes.
1001    
1002    2003-03-06  Bernhard Herzog  <[email protected]>
1003    
1004            * Thuban/UI/classifier.py (ClassGrid.__init__)
1005            (ClassGrid.CreateTable): Move the SetSelectionMode call to
1006            CreateTable because otherwise it triggers an assertion in
1007            wxPython/wxGTK 2.4.
1008    
1009    2003-03-05  Jonathan Coles   <[email protected]>
1010    
1011            * Thuban/common.py: Move FIELDTYPE constants back to table.py.
1012    
1013            * Thuban/Model/load.py: import FIELDTYPE constants from table.
1014    
1015            * Thuban/UI/classifier.py: import FIELDTYPE constants from table.
1016    
1017            * Thuban/Model/table.py: Put FIELDTYPE constants back.
1018    
1019    2003-03-05  Jonathan Coles   <[email protected]>
1020    
1021            * Thuban/UI/classifier.py: Added class documentation.
1022            Fixed RTbug #1713, #1714. Added Move[Up|Down] buttons.
1023            Store just the groups in the table and generate the other
1024            column information when it is requested. Add "None" field
1025            to pull-down to select no classification.
1026    
1027            * Thuban/common.py: Moved FIELDTYPE constants from table.py
1028            (Str2Num): Only catch ValueError exceptions.
1029    
1030            * Thuban/Model/classification.py: Class documentation. Renaming
1031            of methods with Stroke to Line. Groups are stored in a single
1032            list with the default as the first element. Groups are searched
1033            in the order they appear in the list.
1034    
1035            * Thuban/Model/color.py: Documentation.
1036    
1037            * Thuban/Model/layer.py (Layer): Add GetFieldType to retreive
1038            the kind of data represented by a field.
1039    
1040            * Thuban/Model/load.py (ProcessSession): Use proper string
1041            conversion function; fixes RTbug #1713.
1042    
1043            * Thuban/Model/save.py (Saver): Store field type information.
1044    
1045            * Thuban/Model/table.py: Put FIELDTYPE constants in common.py.
1046            (Table): Add field_info_by_name() to retrieve field information
1047            by specifying the field name, not the number.
1048    
1049            * Thuban/UI/mainwindow.py: Function name changes.
1050    
1051            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
1052            get the layer classification once. Don't try to classify
1053            values when the field is None: just use the default properties.
1054    
1055            * Thuban/UI/view.py: Function name changes.
1056    
1057            * Doc/thuban.dtd: Add field_type attribute to a classification.
1058    
1059    2003-03-04  Bernhard Herzog  <[email protected]>
1060    
1061            * Doc/thuban.dtd: Use correct syntax for optional attributes. Make
1062            the fill and stroke layer attributes optional with suitable
1063            default values. Add the stroke_width layer attribute. Use correct
1064            syntax for empty elements. Make the attribute list for labels
1065            refer to the label element.
1066    
1067    2003-03-04  Bernhard Herzog  <[email protected]>
1068    
1069            * setup.py (thuban_build_py.build): Add a comment about distutils in
1070            Python 2.3 containing some of the functionality we implement in
1071            setup.py ourselves.
1072    
1073            * Thuban/UI/classifier.py (ClassGrid.__init__): Set the table
1074            before the selection mode. Doing it the other way round triggers
1075            an assertion in wxWindows.
1076    
1077            * Thuban/Model/save.py (escape): Fix typo in doc-string
1078    
1079            * Thuban/Model/classification.py: Remove unnecessary wxPython
1080            import
1081    
1082    2003-03-04  Jonathan Coles   <[email protected]>
1083    
1084            * Thuban/Model/classification.py (ClassGroupRange.GetProperties):
1085            Parameter 'value' should default to None.
1086    
1087            * Thuban/UI/mainwindow.py: Use Layer.GetClassification() since
1088            the class attribute __classification is now private.
1089    
1090            * Thuban/UI/classifier.py (ClassGrid): Moved OnCellDClick() from
1091            Classifier to ClassGrid. Added support for removing selected rows,
1092            which including code for keeping track of when cells are selected,
1093            and deselected.
1094            (ClassTable): Support for added/removing rows. Fixed a problem
1095            with __ParseInput whereby it would not allow strings (only numbers)
1096            to be entered.
1097            (Classifier): Added button and supporting code for removing
1098            selected rows.
1099    
1100    2003-02-27  Jonathan Coles   <[email protected]>
1101    
1102            * Thuban/common.py: Moved color conversion functions into
1103            Thuban/UI/common.py.
1104            (Str2Num): Now converts the float (not the string) to a long/int
1105            so that an exception isn't thrown.
1106    
1107            * Thuban/UI/common.py: Common functions used in several UI modules
1108    
1109            * Thuban/Model/classification.py: Changed the class hierarchy
1110            so that a Classification consists of Groups which return
1111            Properties when a value matches a Group.
1112    
1113            * Thuban/Model/layer.py: Fixed name resolution problem.
1114    
1115            * Thuban/Model/load.py: Use new Classification and Group functions.
1116    
1117            * Thuban/Model/save.py (Saver.write_attribs): Fixes a test case
1118            failure.
1119            (Saver.write_classification): Use new Classification and Group
1120            functions.
1121    
1122            * Thuban/UI/classifier.py: Changes to use new Classification and Group
1123            functions. Fix to create a tuple with a single value instead of
1124            simply returning the value.
1125    
1126            * Thuban/UI/renderer.py: Use new Classification and Group functions.
1127            Use common.py functions.
1128    
1129            * Thuban/UI/tree.py: Use common.py functions.
1130            
1131            * test/test_classification.py: Use new Classification and Group
1132            classes.
1133    
1134    2003-02-24  Jonathan Coles   <[email protected]>
1135

1137            functions from Thuban color objects to wxWindow colour objects.
1138    
1139            * Thuban/Model/classification.py (Classification): Renamed
1140            GetProperties() to GetClassData(). Used the new iterator
1141            in TreeInfo().
1142            (ClassIterator): Iterator implementation to iterate over the
1143            ClassData objects in a classification object.
1144    
1145            * Thuban/Model/save.py (Saver.write_classificaton): Uses
1146            the new iterator to save the classification information.
1147    
1148            * Thuban/UI/classifier.py (SelectPropertiesDialog): Support
1149            for changing the stroke and fill colors and previewing the
1150            changes.
1151    
1152            * Thuban/UI/mainwindow.py (MainWindow.OpenSession,
1153            MainWindow.SaveSessionAs): Text string changes so the dialogs
1154            have more meaningful titles.
1155    
1156            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Change
1157            Classification method name from GetProperties to GetClassData.
1158    
1159            * Thuban/UI/view.py (MapCanvas.find_shape_at): Use method calls
1160            instead of accessing now non-existent class variables.
1161    
1162    2003-02-24  Bernhard Herzog  <[email protected]>
1163    
1164            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Remove
1165            unneeded Shape() call. Rendering is substantially faster without
1166            it and it avoids some problems with broken shape files.
1167    
1168    2003-02-20  Frank Koormann   <[email protected]>
1169    
1170            Force minimal size of identify and label dialogs. The autosizing
1171            looked too ugly.
1172    
1173            * Thuban/UI/controls.py (RecordListCtrl): Set minimal width for columns.
1174            * Thuban/UI/labeldialog.py (LabelDialog.dialog_layout):
1175            Set size of listctrl.
1176            * Thuban/UI/identifyview.py (IdentifyView.__init__):

1178    
1179    2003-02-19  Jonathan Coles   <[email protected]>
1180    
1181            * test/test_classification.py, test/test_layer.py,
1182            test/test_load.py, test/test_map.py, test/test_session.py:
1183            Updated the tests to use the new functions that are in the
