How to find the global screen position of a Qt app?

I need the global screen position of a Qt widget for which I need the application's global position. How ca开发者_JS百科n this be found?

Thanks.

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.

widget->parentWidget().mapToGlobal( widget->pos() )

widget->mapToGlobal(QPoint(0,0))
