37 | * An ::SDL_QUIT event is generated when the user tries to close the application | ||
38 | * window. If it is ignored or filtered out, the window will remain open. | ||
39 | * If it is not ignored or filtered, it is queued normally and the window | ||
40 | * is allowed to close. When the window is closed, screen updates will | ||
41 | * complete, but have no effect. | ||
42 | * | ||
43 | * SDL_Init() installs signal handlers for SIGINT (keyboard interrupt) | ||
44 | * and SIGTERM (system termination request), if handlers do not already | ||
45 | * exist, that generate ::SDL_QUIT events as well. There is no way | ||
46 | * to determine the cause of an ::SDL_QUIT event, but setting a signal | ||
47 | * handler in your application will override the default generation of | ||
48 | * quit events for that signal. | ||
