Direct Known Subclasses:

public abstract class UIExtension
extends Object

A base class for user interface extensions to the CleanSheets application. Subclasses should override the accessor methods for the components that they provide, and add components as selection listeners whenever required.

A user interface extension should only create one instance of each type of component, and therefore always return the same component when a given method is called.
