Out of OSG/Qt, I think you should: 1) Create a very simple rendering context (associated to the window created by your application);
2) Make that rendering context as the current one; 3) Call glGetString(GL_RENDERER, ...); Steps 1 and 2 are required, since all gl calls need a current rendering context to work with. About steps 1 and 2, you should look at how OSG create the rendering context.

I can get the likes of GL and GLSL version from the osg::GL2Extensions object, and I can see the renderer string being queries in the source code, but I'm having difficulty figuring out how to get it out.
