Class DefaultListCellRenderer
java.lang.Object | +--java.awt.Component | +--java.awt.Container | +--javax.swing.JComponent | +--javax.swing.JLabel | +--javax.swing.DefaultListCellRenderer
- All Implemented Interfaces:
- Accessible, ImageObserver, ListCellRenderer, MenuContainer, Serializable, SwingConstants
- Direct Known Subclasses:
- DefaultListCellRenderer.UIResource, MetalFileChooserUI.FileRenderer, MetalFileChooserUI.FilterComboBoxRenderer
- public class DefaultListCellRenderer
- extends JLabel
- implements ListCellRenderer, Serializable
- extends JLabel
Renders an item in a list.
Implementation Note:
This class overrides
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 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. A future release of Swing will provide support for long term persistence.

DefaultListCellRenderer
public DefaultListCellRenderer()
- Constructs a default renderer object for an item in a list.
| Method Detail |
getListCellRendererComponent
public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus)
- Description copied from interface:
ListCellRenderer - Return a component that has been configured to display the specified
value. That component's
paintmethod 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 interfaceListCellRenderer
- Following copied from interface:
javax.swing.ListCellRenderer- 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.
