3            * Thuban/Model/layer.py (Layer.open_shapefile): Set bbox to None
4            when the shapefile is empty.
5            (Layer.BoundingBox, Layer.LatLongBoundingBox): Both methods may
6            now return None for empty shapefiles. Update doc-strings.
7    
8            * Thuban/Model/map.py (Map.BoundingBox): Add doc-string. Deal with
9            the layer's bbox being None.
10    
11            * Thuban/UI/tree.py (SessionTreeCtrl.update_tree): Deal with the
12            layer's bbox being None.
13    
14            * Thuban/UI/view.py (MapCanvas.shape_selected): Only redraw when
15            necessary.
16            (MapCanvas.__init__): New instance variables, last_selected_layer
17            and last_selected_shape to determine how the selection has
18            changed.
19    
20            * Thuban/UI/tableview.py (TableGrid.__init__): Do not call
21            AutoSizeColumns because it will cause a traversal of the entire
22            table which for large .dbf files will take a very long time.
23    
24    2002-05-14  Bernhard Herzog  <[email protected]>
25    
26            * Thuban/Model/layer.py (Layer.open_shapefile): Choose a better
27            maximum depth for the tree than shapelib does by default.
28    
29    2002-05-10  Bernhard Herzog  <[email protected]>
30    
31            * setup.py (py_modules): The shptree modules doesn't have a

35    
36            * extensions/shapelib/shptree.c (compare_ints): Make arguments

41            maintains to redraw the window during a drag.
42            (MapCanvas.unprojected_rect_around_point): New method to determine
43            a small region around a point for hit-testing.
44            (MapCanvas.find_shape_at): Only test the shapes in a small region
45            around the point.
46    
47            * setup.py: Increment the version to 0.1.2

49            * Thuban/UI/tree.py (SessionTreeCtrl.unsubscribe_all): Remove a

54            * Data/iceland_sample.session, Data/iceland_sample.thuban: Rename

58            all the session channels to subscribe to to update the tree
59            (SessionTreeCtrl.session_changed): Remember the session so that we
60            can unsubscribe properly. Use the new class constant to
61            unsubscribe from the old session and subscribe to the new one.

63            subscriptions of the SessionTreeCtrl.

111            (ScreenRenderer.layer_ids): Make use of the layer's quadtree by
