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.
The set of icons and colors used by DefaultTreeCellRenderer
can be configured using the various setter methods. The value for each property is initialized from the defaults table. When the look and feel changes (updateUI
is invoked), any properties that have a value of type UIResource
are refreshed from the defaults table. The following table lists the mapping between DefaultTreeCellRenderer
property and defaults table key:
Properties
Property | Key |
"leafIcon" | "Tree.leafIcon" |
"closedIcon" | "Tree.closedIcon" |
"openIcon" | "Tree.openIcon" |
"textSelectionColor" | "Tree.selectionForeground" |
"textNonSelectionColor" | "Tree.textForeground" |
"backgroundSelectionColor" | "Tree.selectionBackground" |
"backgroundNonSelectionColor" | "Tree.textBackground" |
"borderSelectionColor" | "Tree.selectionBorderColor" |
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 has been added to the java.beans
package. Please see XMLEncoder
