buttons in opengl
How would you use sdl to get mouse input in opengl? To be more specific how do you convert event.motion.x to opengls coordinate system or vice versa?

SDL and OpenGL use the same x coords. OpenGL will let you define the coordinate system you use. But if you need to invert the y just take the screen height and subtract the y value of your mouse event.
