public class DefaultTreeCellRenderer extends JLabel implements 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.
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:
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.
