(This is the documentation for SDL3, which is under heavy development and the API is changing! SDL2 is the current stable version!)

SDL_SetWindowResizable

Set the user-resizable state of a window.

Header File

Syntax

int SDL_SetWindowResizable(SDL_Window *window, SDL_bool resizable);

Function Parameters

window	the window of which to change the resizable state
resizable	SDL_TRUE to allow resizing, SDL_FALSE to disallow

Return Value

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

Remarks

This will add or remove the window's SDL_WINDOW_RESIZABLE flag and allow/disallow user resizing of the window. This is a no-op if the window's resizable state already matches the requested state.

You can't change the resizable state of a fullscreen window.

Version

This function is available since SDL 3.0.0.
