34 An SDL_QUITEVENT is generated when the user tries to close the application
|
|
|
35 window. If it is ignored or filtered out, the window will remain open.
|
|
|
36 If it is not ignored or filtered, it is queued normally and the window
|
|
|
37 is allowed to close. When the window is closed, screen updates will
|
|
|
38 complete, but have no effect.

40 SDL_Init() installs signal handlers for SIGINT (keyboard interrupt)
|
|
|
41 and SIGTERM (system termination request), if handlers do not already
|
|
|
42 exist, that generate SDL_QUITEVENT events as well. There is no way
|
|
|
43 to determine the cause of an SDL_QUITEVENT, but setting a signal
|
|
|
44 handler in your application will override the default generation of
|
|
|
45 quit events for that signal.
