[osg-submissions] QT issue

[Tomas Hnilica]

Hello Robert,

the problem of keypress events was solved by QT community, attached is 
repaired AdapterWidget.cpp file.
In the AdapterWidget class constructor following line was added:  
setFocusPolicy(Qt::ClickFocus);
Scene disappearing by resizing to minimum still needs to be fixed...

Cheers,
Tomas
