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).

======================== Using SDL with PicoGUI ======================== - Originally contributed by Micah Dowty <micahjd@users.sourceforge.net> PicoGUI is a scalable GUI system with a unique architecture, primarily focused on scalability to various embedded systems. You can find more information including a FAQ at http://picogui.org To use the patch: 1. When compiling, add the "--enable-video-picogui" switch to ./configure 2. When running your program, ensure that the picogui driver for SDL is in use by setting the SDL_VIDEODRIVER environment variable to "picogui". 3. The program must also be linked to the C client library for PicoGUI (libpgui.so). If the program is being compiled with a patched SDL installed this should be done automatically. If you want to use an existing binary with PicoGUI, you can set the LD_PRELOAD environment variable to the path of your libpgui.so file. Capabilities: So far only basic functionality is provided on true color (linear16/24/32) devices. Accessing a memory mapped bitmap, updating the display, and handling mouse/keyboard input. This functionality has been tested with several applications, including mplayer, Xine, sldroids, and Abuse. TODO list: - YUV overlays will be helpful for watching video on set top boxes or other embedded devices that have some graphics acceleration hardware - Account for rotated bitmap storage in pgserver - Support for hiding or changing the cursor - The display should be centered when the SDL application is smaller than the PicoGUI panel - Fullscreen or any other special modes - Support for indexed and grayscale modes - Probably much more... --- The End ---
