I might be wrong (still new to libraries), but: My application is both using:
c:\qt\3.1.1Educational\binqt-mtedu311.dll and c:\progra~1\opensg\qt-mt301.dll So my guess is that the qapplication is made (in main.cpp) 'in' the first dll and classes like OSGQGLWidget are using the second dll. So for these classes, there is no QApplication-object made yet? Compiling OpenSG is my last resort, since this is a school project, so I have to send my own version of OpenSG together with the application.
