This is followed by notification of event occurrence to all listeners of the widget registered for that same event type and in the order in which the listeners were registered on widget.

然后发生该事件的通知会发送给控件中为该事件类型注册的所有监听器，发送顺序是这些监听器在控件上的注册顺序。

Finally, the terminology was made consistent so that a given term (for example, type, instance, specification, or occurrence) has the same general connotation in all contexts in which it appears.

最终，专业术语得到了统一，因此一个特定的条件(例如，类型，实例，规范，或事件)在它出现过的所有上下文中有着相同的全面含义。

Now, when an event of type t1 occurs on that widget, first Filter 1 is informed of the event occurrence, followed by Listener 1, then Listener 2.

现在，当这个控件上产生一个t1类型的事件时，第一个接收到发生该事件的通知的是Filter 1，然后是Listener 1，最后是Listener 2。
