    Not sure that programming a game using X and GTK+ is a good
    solution. Anyway you could have a look to the source code
    of Golgotha (see golgotha.opengames.org), the free game from
    (RIP) Crack Dot Com. Check the display_init() function.

    Like gtk_window_set_decorations() and gtk_window_set_functions()
    (see the GLM 2000-01 on http://logout.free.fr/gtk-glm/index.html
    for further informations)
