   C language opengl ui?
  Hi, I''m writing a little C program which is my first realforay into opengl, and I''m feeling the need fora more structured and useful UI than just pressingkeys - also, I''m about halfway through the capitalletters, having used up all the lowercase ones! I''ve looked, and found glui, pui, glow, which area bit OTT for what I need, but I would use them, exceptmy C++ is rusty and about 10 years out of date, andI don''t really feel equal to the challenge of C++-isingmy existing code, nor relearning that languagesufficiently to make it useable for me - this is a''leisure coding'' project..Also, the code is to run full-screen, so I don''t really wantinterface elements generating their own new windows, just(probably ortho-mode) overlays on the existing window.A lot of stuff must have been written which has game-typemenu and interface code, so I assumed there would be somelib of this type out there, hopefully Free and hopefullyin C, but having looked quite hard, I can''t find it..Anyone know anything that might help me out? Cheers!(And - please! I know C++ is a great language - it''s justmy personal choice not to use it in this circumstance - I''mreally not wanting to spark any religious wars, I''m justlooking for something written in plain old C.. :-)
