|
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. |
