[osg-users] Access to gl context

[Christian Buchner]

Is this the function you're looking for?

osgViewer::GraphicsHandleWin32::getWGLContext
<http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00355.html#abbf6db2b0a8d14f825dd43435862a941>()


I am having some trouble (despite the powers of Google) to find any OSG
example code using getWGLContext()
