widget->mapToGlobal( widget->pos() )

You want the pos property of your top-level window:

This property holds the position of the widget within its parent widget.

If the widget is a window, the position is that of the widget on the desktop, including its frame.

Be sure to also check this part of the Qt docs for details.
