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