SDL_SetWindowFullscreenMode - Man Page

Defined in SDL3/SDL_video.h

#include "SDL3/SDL.h"

bool SDL_SetWindowFullscreenMode(SDL_Window *window, const SDL_DisplayMode *mode);

This only affects the display mode used when the window is fullscreen. To change the window size when the window is not fullscreen, use

SDL_SetWindowSize ().

If the window is currently in the fullscreen state, this request is asynchronous on some windowing systems and the new mode dimensions may not be applied immediately upon the return of this function. If an immediate change is required, call SDL_SyncWindow () to block until the changes have taken effect.

When the new mode takes effect, an

SDL_EVENT_WINDOW_RESIZED
and/or an

SDL_EVENT_WINDOW_PIXEL_SIZE_CHANGED

event will be emitted with the new mode dimensions.

window

the window to affect.

mode

a pointer to the display mode to use, which can be NULL for borderless fullscreen desktop mode, or one of the fullscreen modes returned by SDL_GetFullscreenDisplayModes () to set an exclusive fullscreen mode.

Returns true on success or false on failure; call

SDL_GetError () for more information.

This function should only be called on the main thread.

This function is available since SDL 3.2.0.
