Sorry for being so late but as far as I know there is no better way right now. You should ask the GTK guys, maybe they can help you out.

Re: [Vala] opengl and gtk+-3.0
Is there any way right now to open a GL context up inside of a GTK+3 window using vala? I've been trying to automatically parse the headers glext.h and glxext.h so I could use OpenGL functions that aren't available in the current gl.vapi (anything beyond OpenGL 1.3). So far, I've managed to produce bindings for the functions and the constants defined in both headers. I'm not sure what to do with the types, though. Is there anywhere I can go to find out what all the [IntegerType (rank=9)] stuff means, and how I decide to use rank=9 versus rank=7 or 6, or whatever number strikes my fancy? I've attached my progress so far. There are two python files; each of them parse the header they are named after. Two directories need to be present before either script runs: intermediates and xintermediates. To run the script, type: python vala_glext_header_parser.py debug The scripts produces 4 things: 1. and 2.) A constants.vapi and functions.vapi file either in intermediates or xintermediates, depending on whether the parser is for GL or GLX. 3.) A debug log 4.) A list of the types used in each function printed to the command line. This is so I have an easy-to-reference list of the types used in the .vapi that need binding.
