public class DefaultListCellRenderer extends JLabel implements ListCellRenderer<Object>, Serializable
Implementation Note:
This class overrides
invalidate
,
validate
,
revalidate
,
repaint
,
isOpaque
,
and
firePropertyChange
solely to improve performance.
If not overridden, these frequently called methods would execute code paths
that are unnecessary for the default list 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.
