org.apache.pivot.wtk.Component
Top level abstract base class for all components. In MVC terminology, a component represents the "controller". It has no inherent visual representation and acts as an intermediary between the component's data (the "model") and the skin, an implementation of {@link Skin} which serves asthe "view".
