          javax.swing.JComponent

All Implemented Interfaces:

ImageObserver , MenuContainer , Serializable , Accessible , SwingConstants , TreeCellRenderer

public class DefaultTreeCellRenderer
extends JLabel   
implements TreeCellRenderer   

Displays an entry in a tree. DefaultTreeCellRenderer is not opaque and unless you subclass paint you should not change this. See How to Use Trees in The Java Tutorial for examples of customizing node display using this class.

Implementation Note: This class overrides invalidate, validate, revalidate, repaint, and firePropertyChange solely to improve performance. If not overridden, these frequently called methods would execute code paths that are unnecessary for the default tree 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 .
