Detecting if application focus is on hildon-home or not
 

I have written an homescreen widget with qt and c++ and I need a way to know whenever I'm on desktop or not. MaemoHomescreenAdapter class only has a signal telling me if I'm on the same desktop the widget is, not if I'm on any desktop.

My aim is to let my widget do something ONLY when I'm on desktop, and not while on taskmanager/menu/any other app. Any idea?
