Fixed name resolution problem.
(Layer): Removed references to fill, stroke,
stroke_width attributes. Made the 'classification' attribute private.
New methods for setting/getting the classification.
* Thuban/Model/layer.py (Layer): Remove the
Set[Fill|Stroke|StrokeWidth]() methods. Code should call the
SetDefault*() methods on the layer's classification object.
(Layer.__init__): Use the new SetDefault*() methods in the
Classification class.
Modified these functions to change the null data in the classification rather than keep these values directly in the Layer class. Menu options to change these values work again.
Added a call to build the tree info for classifications. Commented out unnecessary lines.
Replace user string by _() for i18n.
added classification initializations
(Layer.__init__): Make sure we have an absolute filename.
* Thuban/Model/layer.py (Layer.Destroy): Call the unboundd method with self.
(Layer.Destroy): New. Explicitly close the shapefile and destroy the table.
* Thuban/UI/tree.py (color_string): Removed. No longer used. (SessionTreeCtrl.update_tree, SessionTreeCtrl.add_items): Split update_tree into update_tree and add_items. The tree now uses a more generic way to display the contents of the tree. (SessionTreeCtrl): Add a doc string explaining the TreeInfo method * Thuban/Model/layer.py (Layer.TreeInfo), Thuban/Model/extension.py (Extension.TreeInfo), Thuban/Model/map.py (Map.TreeInfo), Thuban/Model/session.py (Session.TreeInfo): Add TreeInfo methods to implement the new tree view update scheme
* Thuban/Model/layer.py (Layer.open_shapefile): Set bbox to None when the shapefile is empty. (Layer.BoundingBox, Layer.LatLongBoundingBox): Both methods may now return None for empty shapefiles. Update doc-strings.
* Thuban/Model/layer.py (Layer.open_shapefile): Choose a better maximum depth for the tree than shapelib does by default.
* Thuban/Model/layer.py (Layer.ShapesInRegion): Remove some debug prints.
* Thuban/Model/layer.py (Layer.__init__): New instance variable shapetree to hold the shapelib quadtree for the shapefile (Layer.open_shapefile): Create the quad tree. (Layer.ShapesInRegion): New method to return the ids of shapes in a given region using the quad tree.
* Thuban/Model/layer.py (Layer.Shape): list append only takes one argument (python <= 1.5.2 erroneously accepted multiuple arguments)
* Thuban/Model/layer.py (Layer.__init__): New parameter and instance variable stroke_width (Layer.SetStrokeWidth): Set the stroke_width.
Open the shapefile immediately. This will cause an exception in case the file can't be opened and we can display an appropriate message.
