Revision 2196
Date: 2006-06-03 11:54:24 -0700 (Sat, 03 Jun 2006)
Author: ed
Changed:
U trunk/dabo/ui/uiwx/dTreeView.py
Log:
Began adding drag/drop for tree nodes. But for some reason (at least on OS X;
I'll try other platforms next) I can only get BeginDrag events; no EndDrag
events ever get received. Any insight would be welcome.
