I've successfully embedded Google Earth into my Qt application using some win32 commands like SetParent(). What I am trying to do now is use a QtOpenGL widget as an overlay that is displayed on top of the Google Earth render window but is transparent everywhere except where I am drawing some objects. Using Google Earth's overlays directly won't work in my case for several reasons. I've tried everything I could think of but I can never see through my QtOpenGL widget to the Google Earth render window behind it. Anyone have any idea how to do this either directly in Qt or with win32 commands?
