SDL_SetWindowAlwaysOnTop

Set the window to always be above the others.

Header File

Defined in SDL_video.h, but apps should only #include "SDL.h"!

void SDL_SetWindowAlwaysOnTop(SDL_Window * window,
                              SDL_bool on_top);

window	The window of which to change the always on top state
on_top	SDL_TRUE to set the window always on top, SDL_FALSE to disable

This will add or remove the window's SDL_WINDOW_ALWAYS_ON_TOP flag. This will bring the window to the front and keep the window above the rest.

This function is available since SDL 2.0.16.
