[SDL] [SPAM] Toggling fullscreen at run time.

[benang at cs.its.ac.id]

Thanks a lot guys. I think maybe toggling between fullscreen and not is
not the best way to solve my problem after all. You see, in my game, I set
it always to be a fullscreen one. But inside the game, there will be an
option for the player to calibrate the touch screen. And this calibration
requires calling an external executable with system() function (I intend
to change it to fork()/exec() after this). This executable uses GTK for
it's GUI. If the game was called with the SDL_FULLSCREEN flag, it can't
show up because the game is always on top . But if I call it without the
SDL_FULLSCREEN flag,the calibration menu showed up. Actually the vendor
already gave me the source code for the calibration executable. So, any
idea to overcome this?

Thanks again.
