All Implemented Interfaces:

ImageObserver , MenuContainer , Serializable , Accessible , ListCellRenderer , SwingConstants

Direct Known Subclasses:

public class DefaultListCellRenderer
extends JLabel   
implements ListCellRenderer   , Serializable   

Renders an item in a list.

Implementation Note: This class overrides invalidate, validate, revalidate, repaint, isOpaque, and firePropertyChange solely to improve performance. If not overridden, these frequently called methods would execute code paths that are unnecessary for the default list cell renderer. If you write your own renderer, take care to weigh the benefits and drawbacks of overriding these methods.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder .
