I am playing around with Qt4 and OpenSG
basically I am following the Tutorial but using the Qt4 GLWidget
Seems that the OpenSG Qt4 native on MacOs is not enabled (why?),
So I am trying to experiment following the testPassiveQt4 example in
OSG QT4 directory
Everything works fine, but when I close the application I get this error:
