SDL_SetWindowFullscreen fails to set window to fullscreen mode yet still returns 0

SDL Development

This code never gives me an error message, but never switches to/from
fullscreen mode either:
while(SDL_WaitEvent(&event)) {
switch (event.type) {
case SDL_QUIT:
return 0;
case SDL_KEYDOWN:
switch (event.key.keysym.sym) {
case ‘f’:
fullscreen = !fullscreen;
if (SDL_SetWindowFullscreen(event.key.windowID, fullscreen) != 0) {
printf (“Unable to switch window to fullscreen mode:
%s\n”, SDL_GetError());
SDL_ClearError();
}
break;
case ‘q’:
case SDLK_ESCAPE:
return 0;
}
break;
case SDL_WINDOWEVENT:
switch (event.window.event) {
case SDL_WINDOWEVENT_RESIZED:
printf(“Window %u resized to %d x %d.\n”,
event.window.windowID, event.window.data1, event.window.data2);
break;
case SDL_WINDOWEVENT_CLOSE:
SDL_HideWindow(event.window.windowID);
return 0;
}
break;
}
}

Also, the SDL_WINDOW_FULLSCREEN flag, when used with SDL_CreateWindow,
produces a window with no border or window decorations centered in the
middle of the screen instead of a fullscreen window.

The full test program is attached.

Yeah, the fullscreen stuff isn’t completely implemented yet, although I’ll
fix the API call to return the correct status. What platform are you
running on?

Linux Mint 7 Gloria x64 (based on Ubuntu 9.04 Jaunty) on an Athlon 64.
video driver would be x11

What’s a good way of learning when the fullscreen stuff is working? I’m
running on Vista SP2(32) with Nvidia 8800 GTX.

I’ve had success in implementing fullscreen/windowed toggling simply by
introducing a mode flag that indicates which mode I ought to be in and
selecting the appropriate value for the flags parameter in SDL_SetVideoMode.
My calls to SDL_SetVideoMode are only in my resize event handler. Oh, I
forgot to mention that this is for OpenGL rendering. I was surprised at how
fast the mode switching was!
