| 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. | |
