Date: Sat, 2 Aug 2003 16:22:51 +0300 From: "Mike Gorchak" Subject: New patches for QNX6 Here my patches for the SDL/QNX: QNXSDL.diff - diff to non-QNX related sources: - updated BUGS file, I think QNX6 is now will be officially supported - configure.in - added shared library support for QNX, and removed dependency between the ALSA and QNX6. - SDL_audio.c - added QNX NTO sound bootstrap insted of ALSA's. - SDL_sysaudio.h - the same. - SDL_nto_audio.c - the same. - SDL_video.c - right now, QNX doesn't offer any method to obtain pointers to the OpenGL functions by function name, so they must be hardcoded in library, otherwise OpenGL will not be supported. - testsprite.c - fixed: do not draw vertical red line if we are in non-double-buffered mode. sdlqnxph.tar.gz - archive of the ./src/video/photon/* . Too many changes in code to make diffs :) : + Added stub for support hide/unhide window event + Added full YUV overlays support. + Added window maximize support. + Added mouse wheel events. + Added support for some specific key codes in Unicode mode (like ESC). + Added more checks to the all memory allocation code. + Added SDL_DOUBLEBUF support in all fullscreen modes. + Added fallback to window mode, if desired fullscreen mode is not supported. + Added stub support for the GL_LoadLibrary and GL_GetProcAddress functions. + Added resizable window support without caption. ! Fixed bug in the Ph_EV_EXPOSE event handler, when rectangles to update is 0 and when width or height of the rectangle is 0. ! Fixed bug in the event handler code. Events has not been passed to the window widget handler. ! Fixed codes for Win keys (Super/Hyper/Menu). ! Fixed memory leak, when deallocation palette. ! Fixed palette emulation code bugs. ! Fixed fullscreen and hwsurface handling. ! Fixed CLOSE button bug. First event was passed to the handler, but second terminated the application. Now all events passed to the application correctly. - Removed all printfs in code, now SDL_SetError used instead of them. - Disabled ToggleFullScreen function. README.QNX - updated README.QNX file. Added much more issues.

 ========================
  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...
