Revision 3455
Date: 2007-10-11 09:52:55 -0700 (Thu, 11 Oct 2007)
Author: Paul
Trac: http://svn.dabodev.com/trac/dabo/changeset/3455
Changed:
U trunk/dabo/ui/uiwx/dGrid.py
Log:
Added a private attribute to dGrid to determine whether to mediate bizobj row
changes through the form (True, the default) or through the bizobj directly.
Setting _mediateRowNumberThroughForm to False completely removed the flickering
on Windows for my grids, and I don't have any particular need for the form
mediation. We can discuss whether to make this a property, or whether to take
away form mediation completely (I haven't thought this through, so I don't know
what my opinion is), or perhaps we can clean up dForm._moveToRowNum() enough so
that it doesn't cause such a performance hit. For now, the attribute provides a
way for me to provide a better-performing grid to my customer.
