JTree rendering extra node and leaf icons at the end of the label

Question

Hi,
Does anyone know how to add an icon to a JTree node or leaf in such a way that it will be displayed behind the text label?
In an example:
- rootnode
- childnode [icon]
|- leaf
+ childnode [icon]
Where -/+ are the default (un)collapse icons
I'd like to apply this to show additional information by using icons with respect to a node.
I couldn't find anything on the net besides changing the default open/close node icons, yet that's not what I'm aiming for here.

use this one.I think it will help u.Gd lk
tree =new JTree(root);
DefaultTreeCellRenderer renderer =(DefaultTreeCellRenderer)tree.getCellRenderer();
renderer.setLeafIcon(new ImageIcon(getClass().getResource("leafimages/3.gif")));
renderer.setClosedIcon(new ImageIcon(getClass().getResource("leafimages/1.gif")));
renderer.setOpenIcon(new ImageIcon(getClass().getResource("leafimages/2.gif")));
renderer.setBackgroundNonSelectionColor(new Color(15,85,134));
renderer.setBackgroundSelectionColor(Color.YELLOW);
renderer.setTextNonSelectionColor(new Color(217,227,227));
renderer.setTextSelectionColor(Color.RED);
renderer.setHorizontalTextPosition(SwingConstants.LEADING);
renderer.setHorizontalAlignment(SwingConstants.CENTER);
tree.setFont(new Font("Tahoma",1,12));
tree.setBackground(new Color(15,85,134));
