Has anyone used cl-opengl inside a standard X-window based drawing widget (one that supports simple refresh and input event call backs ) ?
I am interested in bypassing GLUT (which I currently use) and using another lisp-based toolkit, potentially mcclim. I would like to continue using cl-opengl, though because I like it's interface.
I am assuming that if I have a low-level window , I can create an OpenGL context for it and the cl-opengl binding would just work.

Hi!
I've used cl-opengl with cl-gtk2-gtkglext which is a binding to GtkGlExt library. GtkGlExt provides Gtk+ widget that is painted with opengl calls (https://clgtk2.wordpress.com/2009/08/29/gtkglext-binding/). Window is painted inside 'expose-event' handler with cl-opengl calls, input handling is done by usual Gtk+ events ('motion-notify', 'button-press-event', 'key-press-event' etc.). cl-gtk2 works on Linux and Windows with SBCL and Clozure CL.
