SDL_SetWindowSize

Set the size of a window's client area, in screen coordinates.

Syntax

int SDL_SetWindowSize(SDL_Window *window, int w, int h);

Function Parameters

window the window to change
w the width of the window, must be > 0
h the height of the window, must be > 0

Return Value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

Remarks

The window size in screen coordinates may differ from the size in pixels if the window is on a high density display (one with an OS scaling factor).

This only affects the size of the window when not in fullscreen mode. To change the fullscreen mode of a window, use SDL_SetWindowFullscreenMode()

Version

This function is available since SDL 3.0.0.
