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.

Field Detail

Constructor Detail

### BasicComboBoxRenderer

    public BasicComboBoxRenderer()

Method Detail

### getPreferredSize

    public Dimension getPreferredSize()

  Description copied from class: `JComponent`
  If the preferredSize has been set to a non-null value just returns it. If the UI delegate's getPreferredSize() method returns a non null value then return that; otherwise defer to the component's layout manager.
  Overrides:
    `getPreferredSize` in class `JComponent`
  Following copied from class: `javax.swing.JComponent`
  Returns:
    the value of the preferredSize property
  See Also:
    `JComponent.setPreferredSize(java.awt.Dimension)`

### 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 `paint` method 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 which `getPreferredSize` can be invoked.
  Specified by:
    `getListCellRendererComponent` in interface `ListCellRenderer`
  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.
  See Also:
    `JList`, `ListSelectionModel`, `ListModel`
