Excellent, this was exactly my plan. It's good to hear that it's been
tried before and it worked out well. Was performance OK?

The only way I know of in Cocoa is to create a
transparent window with your cocoa controls on it and
add it as a child window above your OpenGL window.
I've done something similar to this and it worked out
OK.

In Carbon, we were able to do this by creating one
window which
contained an AGL surface, and then a separate Carbon
window. We
"combined" the two windows with window groups and
the visual effect worked.
I'd be OK with this but I don't know if there is a
Cocoa equivalent to
window groups, and if there is a simpler way, I'd
like to know more. I
do know that, in general, Cocoa does not support
Z-ordering for
controls, so that seems like a potential stumbling
block.
