I'd second the other Sean's recommendation, and it was why I asked why
you were using a Rectangle class and a RenderArea class, because as soon
as I saw the RenderArea class, I thought GraphicsView/Scene.

Take a look at http://doc.trolltech.com/4.5/examples.html#graphics-view
(or in your local examples folder, under graphicsview) and see if any of
those examples are a good starting point for what you need to do with
your rectangles...
