- All Implemented Interfaces:
- ImageObserver,- MenuContainer,- Serializable,- Accessible,- ListCellRenderer<Object>,- SwingConstants
- Direct Known Subclasses:
- DefaultListCellRenderer.UIResource,- MetalFileChooserUI.FileRenderer,- MetalFileChooserUI.FilterComboBoxRenderer
 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.
 Please see XMLEncoder.

Method Details- 
getListCellRendererComponentpublic Component getListCellRendererComponent(JList<?> list, Object value, int index, boolean isSelected, boolean cellHasFocus) Description copied from interface:ListCellRendererReturn a component that has been configured to display the specified value. That component'spaintmethod is then called to "render" the cell. If it is necessary to compute the dimensions of a list because the list cells do not have a fixed size, this method is called to generate a component on whichgetPreferredSizecan be invoked.- Specified by:
- getListCellRendererComponentin interface- ListCellRenderer<Object>
- Parameters:
- list- The JList we're painting.
- value- The value returned by list.getModel().getElementAt(index).
- index- The cells index.
- isSelected- True if the specified cell was selected.
- cellHasFocus- True if the specified cell has the focus.
- Returns:
- A component whose paint() method will render the specified value.

isOpaquepublic boolean isOpaque()Overridden for performance reasons. See the Implementation Note for more information.- Overrides:

- Returns:
- trueif the background is completely opaque and differs from the JList's background;- falseotherwise
