Terribly inefficient solution: poll for the window's screen coordinates
(e.g. using a QTimer).

...but this might not work *while* dragging. Or... at all... Ultimately,
you are dependent on the WM to tell you these things, and with WM's
moving increasingly toward compositing-based implementations, that's
like asking a GL texture handle for the coordinates at which it is being
drawn.
