public class HtmlTreeCellRenderer
extends javax.swing.JLabel
implements javax.swing.tree.TreeCellRenderer
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 JavaBeansTM has been added to the java.beans
package. Please see XMLEncoder
