First take a look at http://doc.trolltech.com/4.5/geometry.html

Notice that frameGeometry() is relevant only for top-level windows. I'm 
guessing you are interested in the global position (screen coordinates) 
for a child widget. Here's how you do it:

const QPoint globalPos = child->mapToGlobal(QPoint(0, 0));

Then you'll map (0, 0) of the child widget to global coordinates. You 
can also use mapFromGlobal the other way around.

Hope this helps,
