Date: Thu, 17 Apr 2003 23:27:34 -0400 From: Darrell Walisser Subject: Yet another OS X cursor bug The synopsis: 1. Call SDL_ShowCursor(0); 2. Call SDL_SetVideoMode(); 3. Call SDL_GetEvent(); 3. Call SDL_ShowCursor(1); The result: Sometimes the cursor doesn't come back! Ack! Oddly enough, it does come back when mousing over the dock or clicking in the menu bar. But that's besides the point. The reason why this is happening is a flaw in the handling of activation/deactivation events. The short explanation is that the HideCursor() and ShowCursor() calls must be balanced, but if the cursor was initially hidden, HideCursor() was called again on the activate event - so now the next ShowCursor() fails (as does the next, and the next, for some reason). So, here's the patch. All it does is keep track of the HideCursor()/ShowCursor() calls so that they will always be balanced.

README by Mike Gorchak <mike@malva.ua>, <lestat@i.com.ua>

    OpenGL in window mode  works well  and  stable, in fullscreen
mode too, but fullscreen mode has not been heavily tested.
    If you have QNX RtP 6.1.0 w/ or w/o Patch A you must download
new Photon3D runtime from http://developers.qnx.com. The versions
of OS before 6.1.0 are not supported.

Problems:
1. While  creating  OpenGL  context  software  renderer  mode  is
   artificially selected (QSSL made acceleration only for  Voodoo
   boards in fullscreen mode, sorry but I don't have  this board,
   if you want acceleration - you may remove some line  in source
   code).
2. Photon has some errors in detecting  how  much bits  per pixel
   videomode has.
3. No  shared  libraries  yet.  We  need  manually  set  flag  to
   'configure' --disable-shared.
4. Due to Photon API limitation, flag SDL_HWSURFACE supported on-
   ly in case of desktop bpp is equal requested bpp in window mo-
   de.

Some building issues:

    Run configure script without x11 support, e.g.:

    a) for OpenGL support:
    ./configure --prefix=/usr/local \
                --disable-video-x11 \
                --disable-shared

    b) without OpenGL support:
    ./configure --prefix=/usr/local \
                --disable-video-x11 \
                --disable-shared    \
                --disable-video-opengl

    In test directory  also run  ./configure  script  without x11
support, e.g.:

    ./configure  --with-sdl-prefix=/usr/local      \
                 --with-sdl-exec-prefix=/usr/local \
                 --prefix=/usr/local --without-x
