A ZK component consists of two types of UI object, component and widget.

Component

A component is a Java object running at the server which represents a UI object which can be manipulated by a Java application. A component has all the behavior of a UI object except it has no visual part.

Widget

The widget is a JavaScript object running at the client. This object represents the UI object which interacts with the user. Therefore, a widget usually has a visual appearance, and handles events happening at the client.


Having established that there are two parts to a ZK Component one needs to explore how these parts interact to form a fully interactive user experience.
