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.

BasicComboBoxRenderer
public BasicComboBoxRenderer()
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
