Many Uno interfaces let you register listeners on a special listener interface. This allows you to listen for specific events and call up the appropriate listener method. The CreateUnoListener function waits for the called listener interface and then passes the interface an object that the interface supports. This object is then passed to the method to register the listener.
许多 Uno 接口允许您在特定的侦听器接口上注册侦听器，这样就可以侦听特定的事件，并可以调用适当的侦听器方法。CreateUnoListener 函数等待调用的侦听器接口，然后将一个该接口支持的对象传送给接口。接着该对象被传送到注册侦听器的方法中。
