NSTextField over NSOpenGLView

Question

I have made a window with an NSOpenGLView that I am rendering openGL content into.

I want to add some buttons and text fields to the view: I can add NSTextFields and NSB

Answer 1

The text can be rendered into a texture -- I just used this for a project, did a lot of looking for sample code, and ultimately found Apple's GLString demo code, which was an absolute trove of how-to:

I haven't tried adding buttons, but you can, of course, draw your own and comparing the positions of click events with those of your buttons...
