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.

                                              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
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.
A component whose paint() method will render the specified value.
