Follow-up Comment #5:

You can not create a sub-window in [GLView -initWithFormat...] because you
don't even know if the context will draw to a window. It might draw
fullscreen, or to a pixmap, or to a pixel buffer. You can not know before
[-setView:] or [-setFullscreen], etc.

But you can reparent a NSOpenGLView. As i said, the current (partial and not
tested) implementation destroy the glx context, that will be re-create on the
new window by the next [-openGLContext]. This (simple) behavior might be
wrong.

Please check the attached patches to the current trunk version. You should
then be able to reparent an NSOpenGLView without the context to be destroyed.

1. create the view [-initWithFrame:...] in an unmap or hidden window
2a. get the context and initialize your renderer
2b. load your nib file
3. add the view to your brand new window [-addSubview:]
