SDL_SetWindowBordered

Set the border state of a window.

Header File

Syntax

void SDL_SetWindowBordered(SDL_Window * window,
                           SDL_bool bordered);

Function Parameters

SDL_Window *	window	the window of which to change the border state.
SDL_bool	bordered	SDL_FALSE to remove border, SDL_TRUE to add border.

Remarks

This will add or remove the window's SDL_WINDOW_BORDERLESS flag and add or remove the border from the actual window. This is a no-op if the window's border already matches the requested state.

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

Version

This function is available since SDL 2.0.0.
