Revision 6982
Date: 2011-11-25 10:06:17 -0800 (Fri, 25 Nov 2011)
Author: Ed
Trac: http://trac.dabodev.com/changeset/6982
Changed:
U trunk/dabo/ui/uiwx/dFormMixin.py
Log:
Added the IdleRefreshInterval property to allow more control on the redraw
process. Previously a refresh() was being called on every Idle event, causing a
lot of flicker. Now the default is one refresh per second, but that can be
increased or decreased as needed.
