[PyQt] faster alternative to QHeaderView's resizeToContents?

[Glenn Linderman]

On approximately 5/9/2009 12:28 AM, came the following characters from 
the keyboard of Edwin Marshall:
> I have a QTableView that displays the contents of a model with over

If you have nothing better to try, I'm wondering if unsetting 
QHeaderView.resizeToContents, then loading the data, and then setting it 
again, could provide a speedup?  If it is successful, let me know.  I'm 
very novice to Qt, and working on a non-Qt project at the moment, or I'd 
try it for you.
