Windowbar/border

[Jeff Davis <jdavis genesiswd com>]

I am trying to make a C app (will be GPLed) in GTK+ (a game
specifically). I have never done any graphics-based programming before.

I was wondering how you can make an app with NO windowbar and no border,
just printing graphics to the entire screen, lise many common win32
games (starcraft, diablo, quake2, etc). This is somewhat important to me
(I want it to look professional and consistant with the feel of the
game). Can GTK+ accomplish this under the X system? If not, can you
point me to something that can do this under the X system?

Thanks,
