hmm, looking at the file it seems it is missing an implementation for OS
X [1].
To get you started you probably don't even need OSGQT4Window, so you can
just put #if 0/#endif pair around the body of QT4Window::init(). Take a
look at Source/WindowSystem/QT4/testPassiveQT4.cpp on how to use
OpenSG's PassiveWindow with Qt4.
Cheers,
Carsten
[1] I don't quite understand why the Qt4 window uses platform specific
code to create an OpenGL context instead of the QGLContext class. This
may be a leftover from older (Qt 3 based) code, I'll try to change it,
but it may take a couple of days before I get to it.
