Sure you can borrow bits of code from osgViewerCocoa but they use different design approaches: osgViewerCocoa embeds an osgViewer into a NSApplication with their classes, what you want is to embed a NSWindow / NSOpenGlContext into a GraphicsWindowCocoa class. > > 4.

I started one, but stopped it, because there was no really need on my side, and it's still bare bone without much functionality. Unfortunately there's some more work to do, some functionality could be refactored and used by both implementations (the automatic hiding of the menubar etc) If you want we can tackle this task together, I have some sparetime available and know Objective C a bit. cheers, Stephan _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
