public class FileNameListCellRenderer extends DefaultListCellRenderer
FileNameListCellRenderer is a ListCellRenderer that displays a File or String truncated to the left, not right, so that the most meaningful parts of a file name are shown. For instance the string "/some/where/file.ext" could be rendered as ".../where/file.ext", depending on the component width.

This class can also make sure that the width of the JList associated with a JComboBox are matched (for long names JComboBoxes tend to just expand the drop-down JList to whatever size is needed, so if you're using this renderer with JComboBox you'll need to use this option).
