I'm trying to learn... I went out and bought the book "C++ GUI Programming with Qt 4" - and then realized that my project at work is in Qt 3. I'm making some mods to the project but upgrading to Qt 4 is not an option.

I'm trying to understand how painting is done in QCanvasView. I'm using a QCanvas that has a bright red background and stores a large (dark) image in a QPixmap. When I have an image loaded, it flickers a lot as you scroll through the CanvasView. I set breakpoints during a repaint, and noticed that QCanvasView first shows the QCanvas background color before it shows the pixmap. Can I get it to stop painting the background color when there is an image loaded?

Thanks a lot,
Jim
