Subject:    Determining which screen a full screen window is on

On a multi-head system, is there any easy way to determine which screen a
random full-screen window resides on?

QDesktopWidget is the only Qt/KDE class I can find which gives
multi-screen information, but it only returns the screen number for a
QWidget or a QPoint. I need to be able to find this information for ANY
full-screen window - not just Qt ones - so the QWidget variant is no use.
And KWindowInfo::geometry() and KWindowInfo::frameGeometry() both return a
null QRect for a full screen window, so the QPoint variant doesn't work
either.

Are there any other library functions to give this information? I could
cobble something together based on how QDesktopWidget works, but it's not
ideal for maintainability, and could be fraught from the cross-platform
perspective also.
