public class FileNameListCellRenderer extends javax.swing.DefaultListCellRenderer
FileNameListCellRenderer is aListCellRenderer
that displays aFile
orString
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 aJComboBox
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).- Version:
