In this section we discuss the notifications at the client side.
There are three ways to notify: widget events (Event), DOM events (Event) and client activity watches.
A widget event is triggered by a widget or an application, while a DOM event is triggered by the browser.
A DOM event (Event) is the DOM-level event that is usually triggered by the browser. It is usually listened by the implementation of a widget, rather than the client application.
A client activity watch is a notification for special activities that are not available as DOM events or widget events. For example, the notification when a widget is becoming invisible.
They are mainly used for component development. Application developers rarely need it. For a complete reference, please refer to JavaScript APIs.
