Edit FileTreeModel, as to display names only [urgent]

Here's the TreeModel that I'm using to produce a file tree:


package org.efileuk.uploader ;

import javax.swing.* ;
import javax.swing.tree.* ;
import javax.swing.event.* ;
import java.awt.event.* ;
import java.util.* ;
import java.io.* ;

public class FileTreeModel implements TreeModel, Serializable, Cloneable
{
      
      // V A R I A B L E S
      
      protected EventListenerList listeners ;
      private static final Object LEAF = new Serializable() {} ;
      private Map map ;
      private File root ;
      
      
      // C O N S T R U C T O R S
      
      public FileTreeModel( File root )
      {
            this.root = root ;

            if ( !root.isDirectory() )
                  map.put( root, LEAF ) ;

            this.listeners = new EventListenerList() ;

            this.map = new HashMap() ;
      }
      
      
      // P U B L I C   M E T H O D S
      
      public Object getRoot()
      {
            return root ;
      }

      public boolean isLeaf( Object node )
      {
            return map.get( node ) == LEAF ;
      }

      public int getChildCount( Object node )
      {
            List children = children( node ) ;

            if ( children == null )
                  return 0 ;

            return children.size() ;
      }

      public Object getChild( Object parent, int index )
      {
            return children( parent ).get( index ) ;
      }

      public int getIndexOfChild( Object parent, Object child )
      {
            return children( parent ).indexOf( child ) ;
      }
      
      protected List children( Object node )
      {
            File f = (File ) node ;

            Object value = map.get( f ) ;

            if ( value == LEAF )
                  return null ;

            List children = (List ) value ;

            if ( children == null )
            {
                  File [] c = f.listFiles() ;

                  if ( c != null )
                  {
                        children = new ArrayList( c.length ) ;

                        for ( int len = c.length, i = 0 ; i < len ; i++ )
                        {
                              children.add( c [i] ) ;
                              if ( !c [i].isDirectory() )
                                    map.put( c [i], LEAF ) ;
                        }
                  } else
                        children = new ArrayList( 0 ) ;

                  map.put( f, children ) ;
            }

            return children ;
      }

      public void valueForPathChanged( TreePath path, Object value )
      {}

      public void addTreeModelListener( TreeModelListener l )
      {
            listeners.add( TreeModelListener.class, l ) ;
      }

      public void removeTreeModelListener( TreeModelListener l )
      {
            listeners.remove( TreeModelListener.class, l ) ;
      }
      
      
      // O V E R R I D D E N   M E T H O D S
      
      public Object clone()
      {
            try
            {
                  FileTreeModel clone = (FileTreeModel ) super.clone() ;

                  clone.listeners = new EventListenerList() ;

                  clone.map = new HashMap( map ) ;

                  return clone ;
            } catch ( CloneNotSupportedException e )
            {
                  throw new InternalError() ;
            }
      }
}


The problem is, that all of nodes within the JTree have the value of the entire path, but I only want it to be file name itself. How can I edit this (or my JTree) so that it displays just file names?

Can I have it so that it displays one thing, but when I get it's value, it returns another? (So, displays file names, but when I get the value, it's the entire path name of that file?).

Thanks !!
