This one's mainly for Rick. I am writing a comprehensive template (skeleton and example) C code to use Motif widgets with OpenGL, and I will put it on Github. I have a paper from the X journal (from 1994) that is the most concise example and description of how to do it, but it is a little inadequate in my opinion. Based on that and on a lot of other reading of the X Programing Manual Vol 6 -among others- I have started making this better example. At present it contains pull-down menus, buttons, a help menu, an area where OpenGL drawing is visualized (via GLX), a textbox that acts as a log/console, and a command-line input widget. That is pretty good for most things, but if anyone wants anything more, go ahead and make suggestions. I am working on a commercial project that needs this functionality and that is why I figured it is worth making an example public.
