|
|
* 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.
