openGL/glX colour question for the gurus.
I am looking for help with regards to grabbing an opengl widget/screen as a pixmap object. Under straight X it would go
XgetWindowAttributes(); // To get the colormap and the visual.
This does work to a certain degree for OpenGL widgets, the geometry is correct, however the colours are all screwed up.
Is there a way to accomplish this for an openGL widget using standard X calls?
Thankyou for any help.
