Revision 6105
Date: 2010-10-16 08:53:50 -0700 (Sat, 16 Oct 2010)
Author: Ed
Trac: http://trac.dabodev.com/changeset/6105
Changed:
U trunk/dabo/lib/propertyHelperMixin.py
U trunk/dabo/ui/uiwx/dControlItemMixin.py
Log:
Made the Choices property of list controls dynamic, in that changes to the
value returned by that property will modify the list options of the control.
Formerly, you would have to get the Choices, modify them, and then re-apply
them to the property. Now you can modify them directly, and have the change
reflected in the control.
