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. In additions, you could customize their visual representation by providing an implementation of so-called renderer. The renderer depends on the component. For example, the display of Listbox can be customized by an implementation of ListitemRenderer, and Grid by RowRenderer[1].
