DefaultTreeCellRenderer (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

javax.swing.tree
class DefaultTreeCellRenderer

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              javax.swing.JLabel
                  javax.swing.tree.DefaultTreeCellRenderer

All Implemented Interfaces:: MenuContainer, ImageObserver, Serializable, Accessible, SwingConstants, TransferHandler.HasGetTransferHandler, TreeCellRenderer

Most common way to construct:

DefaultTreeCellRenderer renderer = new DefaultTreeCellRenderer();

Based on 31 examples

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 {@link java.beans.XMLEncoder}.

Parameters:: tree; value; sel; expanded; leaf; row; hasFocus

invalidate

public void invalidate()

Overridden for performance reasons. See the Implementation Note for more information.

Overrides:: invalidate in class Container

paint

repaint

public void repaint()

Overridden for performance reasons. See the Implementation Note for more information.

Overrides:: repaint in class Component

repaint

public void repaint(long tm,
