Fullscreen w/o Glut

Is there a way of drawing in fullscreen mode without the use of Glut? If no, is there a way of associating an existing window with a OpenGL context to Glut?

The problem is I want to add a fullscreen mode to my window which already runs with OpelGL and I don’t want Glut to create its own window.

If I understand your problem correctly you should goto Nehe´s page he has some great tutorials which deals with your problem, I think.
