Is there any way to get SDL to tell you the maximum width and height

Hello !

Use SDL_SetVideoMode with Width=0 and Height=0.
Look at this :

Hi again,
Thanks for the reply Torsten. Unfortunately I’m still having trouble.
I’m using SDL 1.2.11. If I pass 0 for both width and height to
SDL_SetVideoMode() I use my full display resolution the first time.
But if I resize the display to something smaller and then try to go to
fullscreen again, I end up with the smaller display size. In other
words:
surface = SDL_SetVideoMode(0, 0, 32, SDL_OPENGL | SDL_RESIZABLE |
SDL_FULLSCREEN);
surface->w is 1280
surface->h is 1024
surface = SDL_SetVideoMode(800, 600, 32, SDL_OPENGL | SDL_RESIZABLE);
surface->w is 800
surface->h is 600
surface = SDL_SetVideoMode(0, 0, 32, SDL_OPENGL | SDL_RESIZABLE |
SDL_FULLSCREEN);
surface->w is 800
surface->h is 600
SDL_GetVideoInfo() reports the same numbers as my SDL_Surface. Any
other suggestions? I suppose I could start my app in fullscreen mode
and save the original dimensions for later use, but I would prefer to
start it in a smaller window.

How about using SDL_ListModes with SDL_FULLSCREEN in the flags?Am Sunday, dem 28. Oct 2007 schrieb Terry Welsh:

Please use SDL 1.2.12 if possible.

Hi,
1.2.12 behaves the same as 1.2.11. SDL_ListModes seems to do the
trick. I’ll use that for now:
int fullX = 0;
int fullY = 0;
SDL_Rect **modes;
modes = SDL_ListModes(NULL, SDL_FULLSCREEN /| SDL_HWSURFACE/);
if(modes != (SDL_Rect **)0 && modes != (SDL_Rect **)-1){
// zeros should work, but don’t
fullX = modes[0]->w;
fullY = modes[0]->h;
}–

If you’re going to do that, do it with the caveat in mind that the
largest fullscreen resolution is not always the best. (For example,
while my CRT supports up to 2048x1280, at 60Hz I don’t necessarily
want anything going that high.)

Hi SB,
Well, the fullscreen resolution I get this way is 1280x1024 because
that’s what my display is running at when I start my app. My CRT can
also run at a much higher resolution, but it isn’t detected by this
method. Is that what you were worried about?
Eventually I’ll want the user to be able to change between different
fullscreen resolutions, but just switching between windowed and
fullscreen right now is very nice for development.–

Yeah, but that behavior seems a little weird to me. ListModes is
supposed to return the list of possible modes, sorted largest to
smallest. Maybe 1280x1024 is the largest your card can support at your
bit depth?

Anything goes if it’s for “development” purposes, just remember to fix
it later.
It’s worth noting that GetVideoInfo will return the current "real"
video mode if you call it before a SetVideoMode.
