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