        when the shapefile is empty.
        (Layer.BoundingBox, Layer.LatLongBoundingBox): Both methods may
        now return None for empty shapefiles. Update doc-strings.

        * Thuban/Model/map.py (Map.BoundingBox): Add doc-string. Deal with
        the layer's bbox being None.

        changed.

        * Thuban/UI/tableview.py (TableGrid.__init__): Do not call
        AutoSizeColumns because it will cause a traversal of the entire

2002-05-14  Bernhard Herzog  <[email protected]>

        * Thuban/Model/layer.py (Layer.open_shapefile): Choose a better
        maximum depth for the tree than shapelib does by default.

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

        arguments)

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

        * Thuban/UI/identifyview.py (IdentifyGridCtrl): New class to use a
        RecordGrid in the identifyview.

        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

        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

        new class RecordListCtrl

        * Thuban/UI/labeldialog.py (LabelDialog.OnOK): Check whether the

        directly so that Zero numbers are handled properly.
        (LabelListCtrl): Derive from the new class
        SelectableRecordListCtrl

        * Thuban/UI/proj4dialog.py (Proj4Dialog.__init__):

        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)

        * Thuban/UI/tree.py (SessionTreeCtrl, SessionTreeView.__init__):
        Correct the spelling of SessionTreeCtrl. dabbrev is too damn
        convenient :-)

        * 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

        (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

        (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

        * 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.

        * 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

        * 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
        
        * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Fit the map to
        the window when the first layer is added to the map.

        * setup.py (ThubanInstall.run): Honor the build root (self.root)
        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.finalize_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
