    • Applications generating events, and system facilities generating events, send notifications of the events to a system event sink. The event sink is preferably associated with an operating system, and provides an application programming interface for registering listeners. (In one alternative approach, the event sink operates as a centrally-accessible or network-accessible entity, where it may concurrently interact with more than one client.) Upon receiving a notification of an event, the event sink forwards the notification to any registered listeners. Optionally, filters may be used to specify criteria to be met before a notification is forwarded to the listener. An event does not rely on a particular application for displaying the event to an end user. As one example, notification of a newly-arrived e-mail message might be presented in a chat window of an instant messaging client.
    • 生成事件的应用程序和生成事件的系统设施将事件的通知发送到系统事件接收器。 事件接收器优选地与操作系统相关联,并且提供用于注册监听器的应用程序编程接口。 (在一种替代方法中,事件接收器作为可集中访问或网络可访问的实体运行,其可以与多个客户端同时进行交互。)在接收到事件的通知后,事件接收器将通知转发到任何已注册的 听众。 或者,可以使用过滤器来指定将通知转发给侦听器之前要满足的条件。 事件不依赖于特定应用程序来向最终用户显示事件。 作为一个示例,可以在即时消息客户端的聊天窗口中呈现新到达的电子邮件消息的通知。
