Just a quick thought before lunch: you could implement a custom widget (derived from QWidget), draw your bitmap as background and detect the mouse clicks in the corresponding mouse event handler.

Then have a data structure with the "sensitive" QRects and detect wheter mouse x/y was in any one of those QRects.

I am sure there are more elegant ways, but this one should work...

Cheers, Oliver
