[Qt-interest] Reg:: QDesktopWidget

[Mihail Naydenov]

Yes, you have two options:

1. You can grab a desktop screenshot (see examples/desktop/screenshot), than paint it on a full screen widget together with the rect you want. 
2. Use Qt::WA_TranslucentBackground window flag to create a transparent full screen widget and paint just the rect. 
(though, I do not know how the mouse events are handled in this scenario...)

I understand that Qt doesnt allow paint to be done outside the application view but I am wondering if it would be possible to create a widget of screen size hidden and then draw frame or any other way of achieving this ?
