The event type is used to determine what caused the event to be dispatched.
You can query the event type by calling the screen_get_event_property_iv(), specifying the SCREEN_PROPERTY_TYPE constant.
int type;
screen_event_t screen_ev;
screen_create_event(&screen_ev);
screen_get_event(screen_ctx, screen_ev, -1);
screen_get_event_property_iv(screen_ev, SCREEN_PROPERTY_TYPE, &type);
