I guess you called your class SGE for "SDL Graphics Engine" . . . unfortunately, there's already a library for the SDL called SGE (probably standing for the same thing): http://libsdl.org/libraries.php?orde...sge&perpage=50
(It's a very good library, too.) So if you ever publish your engine, you'll probably have to invent a new name for it. Maybe FiFSGE.
For your event code, you could use SDL_WaitEvent() instead of SDL_PollEvent(), if all you're looking for is an SDL_QUIT event. Of course, you'll probably extend that class later to handle all event types, so you'd likely have to change it back.
You could try the SDL newsgroup. http://news.gmane.org/gmane.comp.lib.sdlIs there any good place to get SDL-specific help? Any forums in particular? I know about and have visited places like devmaster.net and gamedev.net, but as to something pertaining specifically to SDL...?
You'll probably get reasonably quick responses here on CBoard, actually, but I imagine the newsgroup is the best place around.
