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

8            Implement selection of multiple selected shapes in the same layer:
9    
10            - Introduce a new class to hold the selection. This basically
11              replaces the interactor which was nothing more than the
12              selection anyway. A major difference is of course that the new
13              selection class supports multiple selected shapes in one layer
14            
15            - Move the object that represents the selection from the
16              application to the canvas. The canvas is a better place than the
17              application because the selection represents which shapes and
18              layer of the map displayed by the canvas are selected and
19              affects how the map is drawn.
20    
21            - Make the selection and its messages publicly available through
22              the mainwindow.
23    
24            - The non-modal dialogs do not get a reference to the interactor
25              anymore as they can simply refer to their parent, the
26              mainwindow, for the what the interactor had to offer.
27    
28            * Thuban/UI/selection.py: New module with a class to represent the
29            selection.
30    
31            * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
32            these unused messages
33    
34            * Thuban/UI/application.py (ThubanApplication.OnInit)
35            (ThubanApplication.OnExit, ThubanApplication.SetSession): The
36            interactor is gone now.
37            (ThubanApplication.CreateMainWindow): There is no interactor
38            anymore so we pass None as the interactor argument for now for
39            compatibility.
40    
41            * Thuban/UI/view.py (MapCanvas.delegated_messages)
42            (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
43            Unsubscribe, delegate messages according to the delegated_messages
44            class variable.
45            (MapCanvas.__getattr__, MapCanvas.delegated_methods): Get some
46            attributes from instance variables as described with the
47            delegated_methods class variable.
48            (MapCanvas.__init__): New instance variable selection holding the
49            current selection
50            (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
51            pass them on to the renderer
52            (MapCanvas.SetMap): Clear the selection when a different map is
53            selected.
54            (MapCanvas.shape_selected): Simple force a complete redraw. The
55            selection class now takes care of only issueing SHAPES_SELECTED
56            messages when the set of selected shapes actually does change.
57            (MapCanvas.SelectShapeAt): The selection is now managed in
58            self.selection
59    
60            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
61            (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
62            Unsubscribe, delegate messages according to the delegated_messages
63            class variable.
64            (MainWindow.delegated_methods, MainWindow.__getattr__): Get some
65            attributes from instance variables as described with the
66            delegated_methods class variable.
67            (MainWindow.__init__): The interactor as ivar is gone. The
68            parameter is still there for compatibility. The selection messages
69            now come from the canvas.
70            (MainWindow.current_layer, MainWindow.has_selected_layer):
71            Delegate to the the canvas.
72            (MainWindow.LayerShowTable, MainWindow.Classify)
73            (MainWindow.identify_view_on_demand): The dialogs don't need the
74            interactor parameter anymore.
75    
76            * Thuban/UI/tableview.py (TableFrame.__init__)
77            (LayerTableFrame.__init__, LayerTableFrame.OnClose)
78            (LayerTableFrame.row_selected): The interactor is gone. It's job
79            from the dialog's point of view is now done by the mainwindow,
80            i.e. the parent. Subscribe to SHAPES_SELECTED instead
81            of SELECTED_SHAPE
82            
83            * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
84            is gone. It's job from the dialog's point of view is now done by
85            the mainwindow, i.e. the parent.
86            
87            * Thuban/UI/classifier.py (Classifier.__init__): The interactor is
88            gone. It's job from the dialog's point of view is now done by the
89            mainwindow, i.e. the parent.
90    
91            * Thuban/UI/tree.py (SessionTreeView.__init__): The interactor is
92            gone. It's job from the dialog's point of view is now done by the
93            mainwindow, i.e. the parent.
94            (SessionTreeCtrl.__init__): New parameter mainwindow which is
95            stored as self.mainwindow. The mainwindow is need so that the tree
96            can still subscribe to the selection messages.
97            (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
98            (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
99            selection is now accessible through the mainwindow. Subscribe to
100            SHAPES_SELECTED instead of SELECTED_SHAPE
101    
102            * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
103            SHAPES_SELECTED message now.
104            (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
105            so deal with multiple shapes
106            (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
107            gone. It's job from the dialog's point of view is now done by the
108            mainwindow, i.e. the parent.
109    
110            * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
111            parameter is now a list of shape ids.
112            (RecordTable.SetTable): The second parameter is now a list of
113            indices.
114    
115            * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the
116            selected_shape parameter and ivar to selected_shapes. It's now a
117            list of shape ids.
118            (MapRenderer.draw_label_layer): Deal with multiple selected
119            shapes. Rearrange the code a bit so that the setup and shape type
120            distinctions are only executed once.
121    
122            * test/test_selection.py: Test cases for the selection class
123    
124    2003-03-11  Jonathan Coles   <[email protected]>
125    
126            * Thuban/Model/load.py: Temporary fix so that the xml reader
127            doesn't cause Thuban to crash.
128    
129            * Thuban/Model/layer.py: Handle the cyclic references between
130            a layer and its classification better, and be sure to disconnect
131            the classification from the layer when the layer is destroyed
132            so that we don't maintain a cyclic reference that may not be
133            garbage collected.
134    
135            * Thuban/Model/classification.py: See comment for layer.py.
