Get mouse position on click?

I am drawing an image in my QMainWindow and I need to get the position of the mouse when it's clicked, so that I can tell where on the image the user clicked. Is there an easy way to do this?

Thanks a lot for your help :)

Via the mouse press event.

If you have a mouse event use that, otherwise you can also see QCursor::pos().
