Qt/Qtopia / A Questions of libSDL
« on: October 14, 2004, 04:01:49 pm »
Hi,
I add the same issue (with libSDL 1.2.7, compiled from official sources). I found this interesting info on a SDL mailing list (http://twomix.devolution.com/pipermail/sdl/2003-January/051398.html):
---
Except for the above modifications, Qtopia port of SDL works pretty
fine and I can enjoy many games in VGA screen on SL-C700 as in the
desktop environment, although I have to allocate an image buffer as
SDL_SetVideoMode( 480, 640, 16, SDL_SWSURFACE) and rotate the VGA
(640x480) screen CW before calling SDL_UpdateRect().
---
And actually, if I try this video mode, I have a better behaviour than with 640x480 (I can display some things on the screen, but as if it was in portrait mode, which makes it unusable)
Unfortunately, I do not quite understand what the author means by "rotate the VGA screen before calling SDL_UpdateRect()"
