Date: Sun, 1 Sep 2002 21:27:54 -0400 (EDT) From: "Ryan C. Gordon" Subject: [SDL] Minor X11 hack: Here's a patch to center a newly-created, non-fullscreen X11 window. While this may or may not be suitable for adding to SDL officially, I didn't want to put any Xlib dependencies in my code directly. To use: - Apply patch/rebuild. - export SDL_WINDOW_POS=center - Call SDL_SetVideoMode as needed. (Ideally, this could be expanded to handle other commands like SDL_WINDOW_POS=20x190, etc, and could be implemented for other targets, but this is really a hack to avoid API changes).
