public abstract class Composite
Composite component: a generic composite component abstract base class.
This class is intended to be used as base class for composite components.
Provides no rendering properties (other than those specified in Component
).
May contain at most one child component. May not contain a Pane
component as
a child.
See the Panel
component for a default implementation of a
single-child container component.
This class provides no benefit if you are providing a custom client-side
synchronization/rendering peer. In such cases, Component
itself should be
derived instead of this class.
