2    
3            * Thuban/Model/table.py: Make writing records work correctly:
4            (Table.__init__): Keep track of whether the DBF is open for
5            writing
6            (Table.write_record): Open the DBF file for writing when necessary
7    
8    2002-08-27  Bernhard Herzog  <[email protected]>
9    
10            * Thuban/Model/table.py (Table.write_record, Table.__init__): Open
11            dbf files only for reading by default. Use a new writable dbf
12            object for writing.
13    
14    2002-08-26  Bernhard Herzog  <[email protected]>
15    
16            * Thuban/UI/mainwindow.py: Refactor the context creation:
17            (MainWindow.Context): New method to return a context
18            (MainWindow.invoke_command, MainWindow.update_command_ui): Use the
19            new method
20    
21            * Thuban/UI/tableview.py (TableGrid, LayerTableGrid): Split the
22            layer table specific code from TableGrid into LayerTableGrid
23            (TableFrame, LayerTableFrame): Split the layer table specific code
24            from TableFrame into LayerTableFrame
25            (LayerTableGrid.select_shape): Remove a debug print
26    
27            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Use the
28            LayerTableFrame
29    
30    2002-08-23  Bernhard Herzog  <[email protected]>
31    
32            * Thuban/Model/layer.py (Layer.__init__): Make sure we have an
33            absolute filename.
34    
35    2002-08-22  Bernhard Herzog  <[email protected]>
36    
37            * Thuban/Model/table.py (Table.write_record): New method to write
38            records.
39            (Table.__init__): Open the DBF file for writing too.
40    
41            * Thuban/UI/controls.py (RecordTable.SetValue): Write the value
42            into the underlying table.
43    
44            * extensions/shapelib/shapefil.h (DBFCommit),
45            extensions/shapelib/dbfopen.c (DBFCommit): New API function to
46            commit any changes made to the DBF file.
47    
48            * Thuban/UI/mainwindow.py (make_check_current_tool)
49            (_tool_command): Put the code that generates the "checked"
50            callback into a separate function so that we can reuse it
51            elsewhere
52    
53            * Thuban/Model/save.py (Saver): New class to handle serializing a
54            session into an XML file. The main reason to introduce a class is
55            that applications built on Thuban can derive from it so that they
56            can save additional information in a session file.
57            (save_session): Delegate almost all the work to the Saver class.
58            Rename the filename argument to file because it may be a file like
59            object now.
60    
61            * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
62            code. Remove the little test code which would be executed when the
63            module is run as a script which didn't work anymore since it can't
64            import the other Thuban modules.
65            (ProcessSession, load_session): Refactor the ProcessSession to
66            have one method for each element start and end tag so that derived
67            classes can easily override the processing of individual tags.
68            Also, always parse with namespaces enabled because applications
69            built on top of Thuban will likely use namespaces if they extend
70            the session file format.
71    
72    2002-08-21  Bernhard Herzog  <[email protected]>
73    
74            * setup.py (ThubanInstall.run): Don't repr install_lib_orig
75            because thubaninit_contents will do it for us.
76    
77    2002-08-16      Jan-Oliver Wagner <[email protected]>
78    
79            * Thuban/UI/mainwindow.py: menu item 'show session tree' now disable if
80            tree window already open
81    
82    2002-08-15  Bernhard Herzog  <[email protected]>
83    
84            * Thuban/Model/layer.py (Layer.Destroy): Call the unboundd method
85            with self.
86    
87            * Thuban/UI/view.py (MapCanvas.OnLeftUp): Only release the mouse
88            when we have actually captured it.
89    
90            * Thuban/Model/layer.py (Layer.Destroy): New. Explicitly close the
91            shapefile and destroy the table.
92    
93            * Thuban/Model/table.py (Table.Destroy): New. Close the DBF file.
94    
95    2002-08-14  Bernhard Herzog  <[email protected]>
96    
97            * Thuban/UI/controls.py (RecordTable.__init__): Remove the unused
98            instance variable columns
99            (RecordTable.GetTypeName): row and col may be negative in some
100            cases.
101    
102            * setup.py (InstallLocal.initialize_options)
103            (InstallLocal.finalize_options, InstallLocal.user_options): New
104            option create-init-file to build a thubaninit.py when running
105            install_local
106            (InstallLocal.run): Create the thubaninit.py module when requested
107            (thubaninit_contents): Split the template into several parts and
108            create a new function thubaninit_contents that creates the
109            contents of a thubaninit module.
110            (ThubanInstall.run): Use the new function to create the thubaninit
111            module.

122            * Thuban/Model/map.py (Map.ClearLayers): New method to delete all
123            layers.
124            (Map.Destroy): Destroy the label_layer as well and call the
125            inherited Desatroymethod first so that no more messages are
126            issued.
127            (Map.RaiseLayer, Map.LowerLayer): Only issue LAYERS_CHANGED
128            message if the stacking order actually has changed. Add
129            doc-strings.

188            (ThubanApplication.CreateMainWindow): Put the mainwindow

193    
194            * Thuban/Model/session.py: Issue a CHANGED message every time

326    
327            * setup.py (thuban_bdist_rpm): Extend this version of bdist_rpm to
328            handle the prefix properly which means that the default for the

360            the events for a command.
361            (MainWindow.add_toolbar_command, MainWindow.add_menu_command):

363            can now bind events too so that it's possible to have commands
364            that are only available through the toolbar.
365            (MainWindow.init_ids): New instance variable events_bound to keep
366            track of for which commands events have been bound.

663            layers by default. Easier to use than the previous default of only

709            Set the initial selection of the combo boxes to reflect the
710            projection we're starting with in a way that works on windows,
711            too.
712    
713            * Thuban/Lib/connector.py (Connector.print_connections): Print the

760            non-nt platforms to thuban_bdist_inno and do it unconditinally
761            since we never want to create the symlinks here
762    
763    2001-09-10  Bernhard Herzog  <[email protected]>
764    
765            * Thuban/UI/mainwindow.py (MainWindow.IdentifyTool): Popup the

779            SelectableRecordListCtrl
780    
781            * Thuban/UI/proj4dialog.py (Proj4Dialog.__init__):
782            (Proj4Dialog.dialogLayout): Make the window resizable and set the
783            size of the text control explicitly to make the sizers work on
