I used the paint function

This is just a random guess, and would probably be a hacky solution, but
maybe you can override mouseMoveEvent on your button (subclass
QPushButton), and in the event handler also send a mouseMoveEvent to the
item under the button (using QcoreApplication::sendEvent? , before calling
the base class implementation?

On the phone now so haven't checked if this is at all doable, just an idea.
