 It should be simple :). QWidget constructor has the QWidget* argument 
specifying the parent - if it's not set, the widget becomes a toplevel 
window, otherwise it's kept inside its parent. In the patch you sent, 
SystemTrayWidget needs the toplevel Plasma widget as its parent, when when 
using mapToGlobal(), instead use mapTo() with the parent (well, or 
mapToParent(), I see). Maybe you'll also need to call raise() on the tray 
widget somewhere. That should do.
