SDL_SetWindowResizable

Set the user-resizable state of a window.

Header File

Syntax

void SDL_SetWindowResizable(SDL_Window * window,
                            SDL_bool resizable);

Function Parameters

SDL_Window *	window	the window of which to change the resizable state.
SDL_bool	resizable	SDL_TRUE to allow resizing, SDL_FALSE to disallow.

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 2.0.5.
