Re: Newbie Q: Is it possible to draw functional "Cocoa Controls" in an OpenGL context?

Matt,

NSOpenGLView doesn't allow subviews but you could certainly put an 
NSView on top of your OpenGL view and put buttons in there.  You 
could subclass that view to pass mouse clicks that weren't handled by 
buttons in the top view down to the OpenGL view.
