[Interest] Unnecessary repaints.

[Bill Crocker]

Hello:

My very first Qt app is large and a little sloppy in
that the QWidget::update() function is being called
*someplace* where it should not, This is causing
unnecessary repaints.

Is there one place I can put a break to find the calls
which actually cause a repaint (and not the calls
which are made when a repaint is already pending).

Or, can you recommend a better way to diagnose
this problem. (The whole thing needs to be rewritten
now that I am older and wiser, but not just yet.)

Thanks.

Bill
