View
From Documentation
The view is the UI of an application. It totally depends on the application's requirements.
As described in the Model section, many ZK components could operate based on models, such as Listbox. There are two approaches to customize the rendering of each item in model: Template and Renderer.
A template is a fragment of the ZUML document that defines how to render each item in ZUML. On the other hand, a renderer is a Java class that renders each item in Java.
