That's going to be a nice battle between you two at Akademy ;-)

Ahh oke, i get it.
For the moment i can even try to use a QGraphicsProxyWidget and just send
WindowPreview to QML. It actually seems fairly easy to do as described
here:
http://qt-project.org/doc/qt-4.8/declarative-cppextensions-qwidgets-qwidgets-cpp.html
or
if it doesn't work i can always put a big red squared stub in it as
placeholder ^_-

It does seem like this will be useful anyway and just one small part that
is problematic (window previews) so I'll continue with it and get it
working.

Thank you for the clarification
