[Qt-interest] Drawing to QImage

[BRM]

I'm looking for some good information on drawing to QImage instead of directly in a QWidget.
Doing a quick google search didn't up much useful information; and while I've taken my first stab at it - my results were not useful either.
I know I'm probably doing something wrong; and would like to be able to read over some stuff on it; but the Qt documentation merely mentions it in passing.

TIA,

Ben
