An SDL_QUITEVENT 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_QUITEVENT events as well. There is no way
|
|
|
|
|
to determine the cause of an SDL_QUITEVENT, but setting a signal
|
|
|
|
|
handler in your application will override the default generation of
|
|
|
|
|
quit events for that signal.
