Hi,
Have a look at Wang Rui's excellent osgRecipes repository, more
particularly osg_qt example:
https://github.com/xarray/osgRecipes/blob/master/cookbook/chapter9/ch09_01/osg_qt.cpp
There was an error where a new camera was incorrectly created rather
than retrieved from the viewer. This has been fixed in the above
provided URL.
Hope this helps,
Émeric
