This class hasn't been used in ages, and LookAndFeelManager makes it unnecessary.
Shamelessly stolen from StackOverflow. Draws nice simple little + and - icons next to tree nodes to indicate expand/collapse ability, instead of the horrible icons included in every major look and feel.

To use this code, you have to let the UIManager know about it: 

 static {
 UIManager.put("Tree.collapsedIcon", new DirTreeNodeIcon('+'));
 UIManager.put("Tree.expandedIcon", new DirTreeNodeIcon('-'));
 }

But a better option is to use LookAndFeelManager to switch the LookAndFeel to something better than one of the Java built-in defaults. Then you won't need this at all.
