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