        (ClassDataPreviewer.Draw): Draw rectangles for polygon layers per
        RTbug #1769.

        * Thuban/UI/dock.py (DockableWindow.UnDock): Restore size and 
        position (although position doesn't work yet under GTK).
        (DockableWindow.Destroy): New. Called when the window must be
        closed. Namely needed when the DockFrame closes and must close
        its children.
        (DockFrame): Listen for EVT_CLOSE and destroy all children.

2003-03-26  Jonathan Coles   <[email protected]>

        This putback contains the code for dockable windows. There is
        no support in wxWindows as of this date for windows that can
        attach themselves to other windows. 

        The current model contains a DockableWindow which has a parent 
        window for when it is detached and a dock window that it puts 
        its contents in when it is docked. The contents of a DockableWindow 
        must be a DockPanel. DockPanel itself derives from wxPanel.

        * Thuban/Model/layer.py (Layer.ClassChanged): Send a LAYER_CHANGED
        message, not a LAYER_LEGEND_CHANGED message.

        * Thuban/Model/map.py (Map): Forward LAYER_CHANGED messages.

        * Thuban/UI/classifier.py (Classifier.__init__): Use wxADJUST_MINSIZE
        as one of the style properties for the fieldTypeText item to
        be sure that its size is correct when the text changes.

        * Thuban/UI/dock.py: New. Classes for the DockPanel and
        DockableWindow.

        * Thuban/UI/legend.py: Added some more buttons and made the
        LegendPanel a DockPanel.

        * Thuban/UI/mainwindow.py: Added sash windows to the main window
        and supporting functions for manipulating the sashes.
        (MainWindow.ShowLegend): Create a DockableWindow with the 
        LegendPanel as the contents.

        * Thuban/UI/messages.py: Added DOCKABLE_* messages

        * Thuban/UI/view.py (MapCanves.SetMap): Listen for LAYER_CHANGED,
        not LAYER_LEGEND_CHANGED, messages.

2003-03-25  Jonathan Coles   <[email protected]>

        * setup.py: Added custom script bdist_rpm_build_script so that
        when the rpm is built the path to wx-config is correct.

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

2003-03-20  Jonathan Coles   <[email protected]>

        Initial implementation of the Legend. 

        * Thuban/UI/legend.py: New. Creates a window that shows the map's
        Legend information and allows the user to add/modify classifications
        and how the layers are drawn on the map.

        * setup.py: New command 'build_docs' which currently uses
        happydoc to generate html documentation for Thuban.

        * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
        Returns a string which is appropriately describes the group.

        * Thuban/Model/layer.py (Layer.SetClassification): Generate a
        LAYER_CHANGED event instead of a LAYER_LEGEND_CHANGED event.

        * Thuban/Model/map.py (Map): Rename messages and use new, more
        specific, messages.

        * Thuban/Model/messages.py: New message to indicate that a layer's
        data has changed (LAYER_CHANGED). New map messages to indicate
        when layers have been added/removed/changed or if the stacking order
        of the layers has changed.

        * Thuban/Model/session.py: Rename and use new messages.

        * Thuban/UI/classifier.py: Remember if any changes have actually
        been applied so that if the dialog is cancelled without an application
        of changes we don't have to set a new classification.
        (ClassDataPreviewer): Pulled out the window specific code and put it
        ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
        symbols on any DC.
        
        * Thuban/UI/mainwindow.py: New code to open the legend.

        * Thuban/UI/view.py: Use new message names.

2003-03-19  Jonathan Coles   <[email protected]>

        * Thuban/UI/main.py (verify_versions): New. Checks the versions
        of Python, wxPython, and some other libraries.

        * extensions/thuban/wxproj.cpp (check_version): Checks the given
        version against what wxproj was compiled with.
        (check_version_gtk): If wxproj was compiled with gtk then check
        the given version against the version of the gtk library 
        currently being used.

2003-03-14  Bernhard Herzog  <[email protected]>

        * test/test_command.py: Run the tests when the module is run as a
        script

2003-03-14  Bernhard Herzog  <[email protected]>

        Implement selection of multiple selected shapes in the same layer:

        - Introduce a new class to hold the selection. This basically
          replaces the interactor which was nothing more than the
          selection anyway. A major difference is of course that the new
          selection class supports multiple selected shapes in one layer
        
        - Move the object that represents the selection from the
          application to the canvas. The canvas is a better place than the
          application because the selection represents which shapes and
          layer of the map displayed by the canvas are selected and
          affects how the map is drawn.

        - Make the selection and its messages publicly available through
          the mainwindow.

        - The non-modal dialogs do not get a reference to the interactor
          anymore as they can simply refer to their parent, the
          mainwindow, for the what the interactor had to offer.

        * Thuban/UI/selection.py: New module with a class to represent the
        selection.

        * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
        these unused messages

        * Thuban/UI/application.py (ThubanApplication.OnInit)
        (ThubanApplication.OnExit, ThubanApplication.SetSession): The
        interactor is gone now.
        (ThubanApplication.CreateMainWindow): There is no interactor
        anymore so we pass None as the interactor argument for now for
        compatibility.

        * Thuban/UI/view.py (MapCanvas.delegated_messages)
        (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
        Unsubscribe, delegate messages according to the delegated_messages
        class variable.
        (MapCanvas.__getattr__, MapCanvas.delegated_methods): Get some
        attributes from instance variables as described with the
        delegated_methods class variable.
        (MapCanvas.__init__): New instance variable selection holding the
        current selection
        (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
        pass them on to the renderer
        (MapCanvas.SetMap): Clear the selection when a different map is
        selected.
        (MapCanvas.shape_selected): Simple force a complete redraw. The
        selection class now takes care of only issueing SHAPES_SELECTED
        messages when the set of selected shapes actually does change.
        (MapCanvas.SelectShapeAt): The selection is now managed in
        self.selection

        * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
        (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
        Unsubscribe, delegate messages according to the delegated_messages
        class variable.
        (MainWindow.delegated_methods, MainWindow.__getattr__): Get some
        attributes from instance variables as described with the
        delegated_methods class variable.
        (MainWindow.__init__): The interactor as ivar is gone. The
        parameter is still there for compatibility. The selection messages
        now come from the canvas.
        (MainWindow.current_layer, MainWindow.has_selected_layer):
        Delegate to the the canvas.
        (MainWindow.LayerShowTable, MainWindow.Classify)
        (MainWindow.identify_view_on_demand): The dialogs don't need the
        interactor parameter anymore.

        * Thuban/UI/tableview.py (TableFrame.__init__)
        (LayerTableFrame.__init__, LayerTableFrame.OnClose)
        (LayerTableFrame.row_selected): The interactor is gone. It's job
        from the dialog's point of view is now done by the mainwindow,
        i.e. the parent. Subscribe to SHAPES_SELECTED instead
        of SELECTED_SHAPE
        
        * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
        is gone. It's job from the dialog's point of view is now done by
        the mainwindow, i.e. the parent.
        
        * Thuban/UI/classifier.py (Classifier.__init__): The interactor is
        gone. It's job from the dialog's point of view is now done by the
        mainwindow, i.e. the parent.

        * Thuban/UI/tree.py (SessionTreeView.__init__): The interactor is
        gone. It's job from the dialog's point of view is now done by the
        mainwindow, i.e. the parent.
        (SessionTreeCtrl.__init__): New parameter mainwindow which is
        stored as self.mainwindow. The mainwindow is need so that the tree
        can still subscribe to the selection messages.
        (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
        (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
        selection is now accessible through the mainwindow. Subscribe to
        SHAPES_SELECTED instead of SELECTED_SHAPE

        * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
        SHAPES_SELECTED message now.
        (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
        so deal with multiple shapes
        (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
        gone. It's job from the dialog's point of view is now done by the
        mainwindow, i.e. the parent.

        * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
        parameter is now a list of shape ids.
        (RecordTable.SetTable): The second parameter is now a list of
        indices.

        * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the
        selected_shape parameter and ivar to selected_shapes. It's now a
        list of shape ids.
        (MapRenderer.draw_label_layer): Deal with multiple selected
        shapes. Rearrange the code a bit so that the setup and shape type
        distinctions are only executed once.

        * test/test_selection.py: Test cases for the selection class

2003-03-11  Jonathan Coles   <[email protected]>

        * Thuban/Model/load.py: Temporary fix so that the xml reader
        doesn't cause Thuban to crash.

        * Thuban/Model/layer.py: Handle the cyclic references between
        a layer and its classification better, and be sure to disconnect
        the classification from the layer when the layer is destroyed
        so that we don't maintain a cyclic reference that may not be
        garbage collected.

        * Thuban/Model/classification.py: See comment for layer.py.

2003-03-12  Jan-Oliver Wagner <[email protected]>

        * HOWTO-Release: New. Information on the steps for releasing
        a new version of Thuban.

2003-03-11  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py: Add normal border to SelectPropertiesDialog.
        Use True instead of true.
        (Classifier): Should have a single panel in which all the controls lie.

        * Thuban/UI/proj4dialog.py: Add normal border.

        * Thuban/UI/tree.py: Fixed problem with bad item images under Windows.

        * Thuban/UI/mainwindow.py: Use True instead of true.

        * setup.py: Update some definitions to use wxWindows2.4 files

        * Data/iceland_sample_class.thuban: Fixed file so that the
        field_type information is present.

2003-03-10  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py (Classifier.__init__): Make the
        field type label grow so that when the text changes the
        size is updated correctly. This may be a wxWindows bug.

2003-03-10  Jonathan Coles   <[email protected]>

        * Thuban/UI/application.py: Changed SESSION_CHANGED to
        SESSION_REPLACED.

        * Thuban/UI/classifier.py: Wrap text with _(). 
        (ClassGrid.CreateTable): Set dimensions and size hints here,
        instead of in Reset, so we only set the size once.

        * Thuban/UI/dialogs.py: Don't need Shutdown(); just use Close()!

        * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
        Call Close() instead of Shutdown().

        * Thuban/UI/messages.py: Changed SESSION_CHANGED to SESSION_REPLACED.

        * Thuban/UI/tree.py: Changed SESSION_CHANGED to SESSION_REPLACED.
        Go back to using OnClose() instead of Shutdown().

2003-03-10  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py (Classifier): SelectField() needed
        to know the old field index as well as the new one.

2003-03-10  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py (Classifier): Use __SelectField()
        to correctly set the table information and call this from
        __init__ and from _OnFieldSelect so that all the information
        is up to date when the dialog opens and when a field is changed.

2003-03-10  Jonathan Coles   <[email protected]>

        * Thuban/Model/classification.py (Classification): Don't use
        layer's message function directly, use the ClassChanged() method
        when then classification changes. SetField/SetFieldType/SetLayer
        must keep the information about field name and field type in
        sync when an owning layer is set or removed.

        * Thuban/Model/layer.py: Added ClassChanged() so that the 
        classification can tell the layer when its data has changed.
        (Layer.SetClassification): Accepts None as an arguement to 
        remove the current classification and correctly handles
        adding a new classification.

        * Thuban/Model/load.py: Comment out print statement

        * test/test_classification.py, test/test_save.py: New and
        improved tests.

2003-03-07  Jonathan Coles   <[email protected]>

        * Thuban/Model/classification.py: Implemented __copy__ and
        __deepcopy__ for ClassGroup* and ClassGroupProperites so
        they can easily be copied by the classifier dialog.
        (ClassGroupProperites.__init__): The default line color should
        have been Color.Black.

        * Thuban/UI/classifier.py: Setting and Getting table values now
        uses a consistent set of functions.
        (Classifier): Now non-modal. Has field type label which changes
        as the field changes. Keep track of buttons in a list so that
        we can enable/disable the buttons when the None field is selected.
        (SelectPropertiesDialog): Add buttons to make the colors transparent.

        * Thuban/UI/dialogs.py (NonModalDialog.Shutdown): New method which
        does what OnClose did, but can be called by the application to
        close a window. Needed when a session changes, and we have to
        close the classifier windows.

        * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
        Shuts down open dialogs. Used when a new session is created
        or a session is opened.
        (MainWindow.SaveSession): Should only call application.SaveSession()
        if we don't call SaveSessionAs first.
        (MainWindow.Classify): Allow different classifier dialogs for
        different layers.

        * Thuban/UI/tree.py (SessionTreeView): Remove OnClose and let
        the parent class handle it. Add Shutdown() to unsubscibe from
        event notification and call the parent Shutdown(). This was
        necessary so the application can close the tree window.

2003-03-06  Jonathan Coles   <[email protected]>

        * Thuban/Model/classification.py: Minor documentation changes,
        Addition of __eq__ and __ne__ methods.
        (Classification.SetLayer): prevent recursion between this method
        and Layer.SetClassification().

        * Thuban/Model/color.py: Addition of __eq__ and __ne__ methods.

        * Thuban/Model/layer.py (SetClassification): prevent recursion 
        between this method and Classification.SetLayer().

        * test/test_classification.py, test/test_load.py,
        test/test_session.py: Fixed and added tests for the classification
        classes.

2003-03-06  Bernhard Herzog  <[email protected]>

        * Thuban/UI/classifier.py (ClassGrid.__init__)
        (ClassGrid.CreateTable): Move the SetSelectionMode call to
        CreateTable because otherwise it triggers an assertion in
        wxPython/wxGTK 2.4.

2003-03-05  Jonathan Coles   <[email protected]>

        * Thuban/common.py: Move FIELDTYPE constants back to table.py.

        * Thuban/Model/load.py: import FIELDTYPE constants from table.

        * Thuban/UI/classifier.py: import FIELDTYPE constants from table.

        * Thuban/Model/table.py: Put FIELDTYPE constants back.

2003-03-05  Jonathan Coles   <[email protected]>

        * Thuban/UI/classifier.py: Added class documentation.
        Fixed RTbug #1713, #1714. Added Move[Up|Down] buttons.
        Store just the groups in the table and generate the other
        column information when it is requested. Add "None" field
        to pull-down to select no classification.

        * Thuban/common.py: Moved FIELDTYPE constants from table.py 
        (Str2Num): Only catch ValueError exceptions.

        * Thuban/Model/classification.py: Class documentation. Renaming
        of methods with Stroke to Line. Groups are stored in a single
        list with the default as the first element. Groups are searched
        in the order they appear in the list.

        * Thuban/Model/color.py: Documentation.

        * Thuban/Model/layer.py (Layer): Add GetFieldType to retreive
        the kind of data represented by a field.

        * Thuban/Model/load.py (ProcessSession): Use proper string
        conversion function; fixes RTbug #1713.

        * Thuban/Model/save.py (Saver): Store field type information.

        * Thuban/Model/table.py: Put FIELDTYPE constants in common.py.
        (Table): Add field_info_by_name() to retrieve field information
        by specifying the field name, not the number.

        * Thuban/UI/mainwindow.py: Function name changes.

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
        get the layer classification once. Don't try to classify 
        values when the field is None: just use the default properties.

        * Thuban/UI/view.py: Function name changes.

        * Doc/thuban.dtd: Add field_type attribute to a classification.

2003-03-04  Bernhard Herzog  <[email protected]>

        * Doc/thuban.dtd: Use correct syntax for optional attributes. Make
        the fill and stroke layer attributes optional with suitable
        default values. Add the stroke_width layer attribute. Use correct
        syntax for empty elements. Make the attribute list for labels
        refer to the label element.

2003-03-04  Bernhard Herzog  <[email protected]>

        * setup.py (thuban_build_py.build): Add a comment about distutils in

        (Table.__init__): Open the DBF file for writing too.

        * Thuban/UI/controls.py (RecordTable.SetValue): Write the value
        into the underlying table.

        extensions/shapelib/dbfopen.c (DBFCommit): New API function to
        commit any changes made to the DBF file.

        * Thuban/UI/mainwindow.py (make_check_current_tool)
        (_tool_command): Put the code that generates the "checked"
        callback into a separate function so that we can reuse it
        elsewhere

        * Thuban/Model/save.py (Saver): New class to handle serializing a
        session into an XML file. The main reason to introduce a class is
        that applications built on Thuban can derive from it so that they
        can save additional information in a session file.
        (save_session): Delegate almost all the work to the Saver class.
        Rename the filename argument to file because it may be a file like
        object now.

        * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
        code. Remove the little test code which would be executed when the
        module is run as a script which didn't work anymore since it can't
        import the other Thuban modules.
        (ProcessSession, load_session): Refactor the ProcessSession to
        have one method for each element start and end tag so that derived
        classes can easily override the processing of individual tags.
        Also, always parse with namespaces enabled because applications
        built on top of Thuban will likely use namespaces if they extend
        the session file format.

2002-08-21  Bernhard Herzog  <[email protected]>

        * setup.py (ThubanInstall.run): Don't repr install_lib_orig

        around to speed up most redraws:
        (MapCanvas.__init__): New instance variable bitmap which holds the
        bitmap

        current_position
        (MapCanvas.set_current_position): New method to set
        current_position. Issue a VIEW_POSITION event
        (MapCanvas.CurrentPosition): New public method to return the value
        of current_position. Should be called when the VIEW_POSITION event
        is processed.

        extensions/shapelib/dbfopen.c: Update to the versions of shapelib
        1.2.9

        * setup.py (Lib.wxproj extension): Don't link shpopen.c and put
        the pyshapelib directoy into the list of include dirs, so that
        pyshapelib_api.h can be found.

        * extensions/thuban/wxproj.cpp (pyshapelib_api): New variable that
        holds the pyshapelib C-API

        menu

2002-02-15  Bernhard Herzog  <[email protected]>

        * Thuban/Model/layer.py (Layer.Shape): list append only takes one
        argument (python <= 1.5.2 erroneously accepted multiuple
        arguments)

2002-02-04  Bernhard Herzog  <[email protected]>

        * Thuban/UI/identifyview.py (IdentifyGridCtrl): New class to use a
        RecordGrid in the identifyview.
        (IdentifyView.__init__): Use IdentifyGridCtrl instead of

        * Thuban/UI/controls.py (RecordTable, RecordGridCtrl): New classes
        implementing a grid for a single row of a thuban table.

        * Thuban/UI/view.py (MapCanvas.SelectShapeAt): Search through all
        layers by default. Easier to use than the previous default of only
        searching through the select layer which meant that if no layer
        was selected, you couldn't select a shape.

        * Thuban/UI/tableview.py (TableGrid.__init__): Fix typo

        * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Honour the

        Set the initial selection of the combo boxes to reflect the
        projection we're starting with in a way that works on windows,
        too.

        * Thuban/Lib/connector.py (Connector.print_connections): Print the
        puiblisher's ids in hex to make it easier to compare them to the
        standard repr of python methods

        messages

2001-09-13  Bernhard Herzog  <[email protected]>

        * Thuban/UI/tree.py (SessionTreeCtrl.OnSelChanged): Make sure to
        deselect the layer if no layer is selected

        * Thuban/UI/view.py (MapCanvas.OnPaint): Only delay drawing to
        idle time when there actually is something to draw. If there's
        nothing to draw simply clear the window
        (MapCanvas.do_redraw): Call dc.EndDrawing and add some comments.
        (MapCanvas.SetMap): force a redraw in all cases because
        FitMapToWindow doesn't always do it.
        (MapCanvas.ZoomFactor): Add an optional parameter, center, to
        specify the point to move into the center of the window
        (ZoomOutTool.MouseUp, ZoomInTool.MouseUp): If the mouse wasn't
        dragged, zoon in/out by a factor of 2
        (MapCanvas.find_shape_at): Iterate backwards (i.e. with decreasing
        index, i.e. reversed drawing order) so that objects appearing to
        be in from of others are selected first. This is probably mostly
        relevant for point shapes where the symbols used may overlap

        * Thuban/Model/session.py (create_empty_session): Unset the
        modified bit before returning it

        * Thuban/UI/mainwindow.py (MainWindow.NewSession): Use

        * Thuban/UI/mainwindow.py (MainWindow.__init__): Set the size of
        the tool bitmaps.
        (MainWindow.OnClose, MainWindow.save_modified_session): Separate
        the code that asks whether the session should be saved into the
        new method save_modified_session.
        (MainWindow.OpenSession, MainWindow.NewSession): Use the new
        method to save modified session here too.

2001-09-11  Bernhard Herzog  <[email protected]>

        * setup.py (InnoIconItem): fix typo

        (thuban_bdist_inno.run):
        (bdist_inno.run): Move the decision not to create symlinks on
        non-nt platforms to thuban_bdist_inno and do it unconditinally
        since we never want to create the symlinks here

2001-09-10  Bernhard Herzog  <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.IdentifyTool): Popup the
        identify view immediately

        * Thuban/UI/controls.py: New file with two classes RecordListCtrl
        and SelectableRecordListCtrl that implement the code shared by the
        identify view and the label dialog

        * Thuban/UI/identifyview.py (IdentifyListCtrl): Derive from the
        new class RecordListCtrl

        * Thuban/UI/labeldialog.py (LabelDialog.OnOK): Check whether the
        return value of GetValue is None instead of using it as a boolean
        directly so that Zero numbers are handled properly.
        (LabelListCtrl): Derive from the new class
        SelectableRecordListCtrl

        * Thuban/UI/proj4dialog.py (Proj4Dialog.__init__):
        (Proj4Dialog.dialogLayout): Make the window resizable and set the
        size of the text control explicitly to make the sizers work on
        both Windows and X.

2001-09-07  Bernhard Herzog  <[email protected]>

        * Thuban/UI/view.py (MapCanvas.find_shape_at):Add a new parameter
        that can limit the search to the currently selected layer.
        (MapCanvas.SelectShapeAt): Make sure that the currently selected
        layer stays selected even when no shape is found
        (MapCanvas.FitRectToWindow): If the rect has zero with or zero
        height do nothing (avoids zero division errors)

2001-09-06  Bernhard Herzog  <[email protected]>

        * Thuban/UI/tree.py (SessionTreeCtrl, SessionTreeView.__init__):
        Correct the spelling of SessionTreeCtrl. dabbrev is too damn
        convenient :-)
        (SessionTreeCtrl.__init__, SessionTreeCtrl.update_tree): Introduce
        a new instvar layer_to_item to map layers to tree items
        (SessionTreeCtrl.layer_selected): Select the appropriate tree item

        * Thuban/UI/interactor.py (Interactor.SelectedLayer):
        (Interactor.HasSelectedLayer): New methods to query the current
        selection

        * Thuban/UI/mainwindow.py (MainWindow.__init__):
        (MainWindow.LayerShowTable):
        (MainWindow.identify_view_on_demand): Store the interactor in an
        instvar and use that reference instead of going through main.app

        * Thuban/UI/mainwindow.py (MainWindow.ShowSessionTree):
        * Thuban/UI/application.py (ThubanApplication.OnInit):
        * Thuban/UI/main.py (main): Create the session tree view in main
        with the new mainwindow method ShowSessionTree and not directly
        the application's OnInit method

        * Thuban/UI/tree.py (myTreeCtrlPanel):
        (SessioinTreeCtrl): Rename to SessioinTreeCtrl and turn it into a
        TreeCtrl isntead of a panel. This affects most method since we now
        refer to self instead of self.tree

        showing the session tree.

        * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Pass the

        (TableGrid.OnSelectCell):
        (TableFrame.__init__):
        (TableFrame.row_selected):
        Selecting rows in the grid view now updates the selected shapes
        through the TableFrame. To achieve this we derive TableGrid from
        Publisher and introduce the message type ROW_SELECTED which the
        TableFrame subscribes to and which is issued by OnRangeSelect and
        OnSelectCell

        (DataTable.SelectRow): Removed because it's no longer needed in
        the row/shape selection scheme

        * Thuban/UI/dialogs.py: New file implementing common classes for
        dialogs

        * Thuban/UI/tableview.py (TableGrid.__init__): Don't subscribe to

        parent.
        (TableGrid.select_shape): Only update the selection if the shape
        is not None.
        (TableFrame): Inherit from the new NonModalDialog class.
        (TableFrame.__init__, TableFrame.select_shape): Handle the

        of opened non-modal dialogs.

        (MainWindow.__init__): Initialize the new non-modal dictionary
        management code
        (MainWindow.LayerShowTable): maintain separate dialogs for each
        table using the non-modal dialog management code to only open a
        view once for each table.

        (MainWindow.IdentifyTool):
        (MainWindow.__init__):
        (MainWindow.identify_view_on_demand): Don't open the identify view
        in IdentifyTool anymore. This will be done automatically by the
        new method identify_view_on_demand which handles the
        SELECTED_SHAPE message so that the identify view will be opened on
        demand

        * Thuban/UI/identifyview.py (IdentifyListCtrl.__init__): Remove
        the interactor argument. The SELECTED_SHAPE message is now handled
        by the parent.
        (IdentifyView.__init__): Add the interactor argument so that we
        can handle the SELECTED_SHAPE message here
        (IdentifyView.selected_shape): New method to handle the
        SELECTED_SHAPE messages

        * Thuban/UI/identifyview.py (IdentifyView): Derive from the new
        NonModalDialog class
        (IdentifyView.OnClose): Extend the inherited version to
        unsubscribe SELECT_SHAPE

        * Thuban/Model/session.py (Session.UnsetModified): Remove debug prints

2001-09-05  Bernhard Herzog  <[email protected]>

        * Thuban/UI/view.py (MapCanvas.__init__): New argument, interactor.

        * Thuban/UI/mainwindow.py (MainWindow.__init__): New argument
        interactor to pass through to the MapCanvas

        * Thuban/UI/application.py (ThubanApplication.OnInit): Use the new
        argument to the MainWindow constructor to get rid of the ugly hack
        that made main.app available early just so that the mapcanvas
        could access the interactor object.

2001-09-04  Bernhard Herzog  <[email protected]>

        * Thuban/UI/mainwindow.py (MainWindow.RunMessageBox): New method
        that runs a modal message box
        (MainWindow.OnClose): Use the new method
        (MainWindow.RemoveLayer): Just do nothing in case no layer is
        selected. The command should be grayed out anyway, so there's no
        need to pop up a message box.
        (MainWindow.AddLayer): Pop up a message box with an error message
        if the shape file can't be opened

        * Thuban/Model/layer.py (Layer.__init__): Open the shapefile
        immediately. This will cause an exception in case the file can't
        be opened and we can display an appropriate message.

        * MANIFEST.in: Add extensions/pyprojection/LICENSE

        * setup.py (thuban_bdist_rpm): New class implementing a Thuban
        specific bdist_rpm command.

        * Thuban/UI/main.py: Catch ImportError exceptions when importing
        the locale module because it may not be available on some
        installations.

        * extensions/pyprojection/LICENSE: Copy of the license text in
        Projection.i. Having it in a separate file makes it easier to
        refer to license text in e.g. RPMs

2001-09-03  Bernhard Herzog  <[email protected]>

        * setup.py: use wx-config instead of wxgtk-config because it's
        more generic

        * setup.py (ThubanInstall.get_outputs): Add the symlink in
        <prefix>/bin to the outputs
        (ThubanInstall.link_file): New method to link files. We need this
        because the standard copy_files refuses to link non-existing
        files.
        (ThubanInstall.run): Remove the leading install root from the
        script filename if an install root was specified and use the new
        link_file method

        when linking thuban.py to <prefix>/bin

2001-08-31  Bernhard Herzog  <[email protected]>

        * setup.py: In the setup call, the install parameters shouldn't
        have trailing slashes because distutils on non-posix platforms
        doesn't like that. The same applies to other directories like
        "Resources/Bitmaps"

        In the configuration section for nt, move the wxWindows directory
        optins into the part clearly marked as editable.

        (InstallLocal.initialize_options):
        (InstallLocal.user_options): remove the currently unused debug
        flag
        (thuban_build_py.find_all_modules): Add this method so that it
        works for our case of having packages and modules in one
        distribution as well.
        (ThubanInstall.initialize_options):

        (ThubanInstall.user_options):
        (ThubanInstall.boolean_options): Add new options, do-symlink and
        extra files. Since these are the first ThubanInstall specific
        options, override user_options and boolean_options
        (ThubanInstall.run): Honor the new do-symlink and extra-files
        options.
        (ThubanInstall.get_outputs): Add to override the base-class's
        version and add the extra-files to the outputs
        (bdist_inno): New class for windows distributions with Inno Setup
        (InnoIconItem): Helper class for bdist_inno
        (thuban_bdist_inno): Thuban specific version of bdist_inno. Added
        this together with the appropriate parameters, to the setup call.

        * setup.cfg (bdist_inno): added new section for the inno setup
        installer

        * Thuban/UI/tree.py (myTreeCtrlPanel.__init__): New inst var
        changing_selection to avoid recursive selection events when
        modifying the selection in response to a selection event.
        (myTreeCtrlPanel.normalize_selection): Set the new inst var when
        changing the tree's selection.
        (myTreeCtrlPanel.OnSelChanged): Only normalize the selection when
        we're not being called indirectly from normalize_selection.

        * Thuban/UI/mainwindow.py (MainWindow.update_command_ui): Call
        event.Check only if the command is actuall checkable.
        (MainWindow.__init__): Call the toolbar's Realize method to make
        sure that the items are actually shown

2001-08-28  Bernhard Herzog  <[email protected]>
