Revision 741 - (hide annotations)
Fri Apr 25 09:14:27 2003 UTC (21 years, 10 months ago) by jonathan
Original Path: trunk/thuban/Thuban/UI/projdialog.py
File MIME type: text/x-python
File size: 30832 byte(s) 
(ProjFrame._OnAddToList): Renamed from
        ProjFrame._OnSaveAs. Removed old dead code from previous
        implementation.
(ProjFrame._OnExport): Add support for exporting more than one
        projection to a single file.
(ProjFrame.__FillAvailList): use string formatting (% operator)
        to build strings that are (partly) translated. Fixes RTbug #1818.
