Tree Cell Renderer settings for displaying complete text.

Question

I have a tree model. It is of the form
abc (123.00)
-----def (456.00)
----------ghi (678.00)
But it is displayed like
abc (12...
-----def (45..
----------ghi (67..
I don't want the numbers in the end to be missing. It is a problem for the user to expand them everytime.
I am using, JTree and using my cell renderer, with following properties in
super.getTreeCellRendererComponent(tree, false, X, false, false, row, false);I did try to change it to
super.getTreeCellRendererComponent(tree, false, X, TRUE, false, row, false);but still no success.
My function toString() for tree elements looks like this
                 double u = "123.00";
                 String num = String.format("%.2f", u);
                 return getName() + " (" + num  + ")";Can you please suggest possible way around for this?

package abc;

public class NewJPanel extends javax.swing.JPanel implements MouseListener {
     public static void main(String[] args) {
          JFrame frame = new JFrame();
          frame.getContentPane().add(new NewJPanel());
          frame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
          frame.pack();
          frame.setVisible(true);
     JTree m_tree;
    private JScrollPane myPane;
    float multi = 1;
    DefaultTreeModel tree = new DefaultTreeModel(new ContainerNode("root"));
    DefaultMutableTreeNode parent = (DefaultMutableTreeNode)tree.getRoot();
     public NewJPanel() {
        super(new BorderLayout());
        String util = String.format("%.2f", 123456789012345679801234567980.00);
        util = "abc" + " (" + util  + ")";
            DefaultMutableTreeNode e = new DefaultMutableTreeNode(util);
            tree.insertNodeInto(e, parent, 0);
        m_tree = new JTree(tree);
        m_tree.setEditable(false);
        m_tree.setDragEnabled(false);
        m_tree.getSelectionModel().setSelectionMode(TreeSelectionModel.CONTIGUOUS_TREE_SELECTION);
        m_tree.setAutoscrolls(true);
        m_tree.setPreferredSize(new java.awt.Dimension(397, 297));
        myPane = new JScrollPane(m_tree);
        myPane.setAutoscrolls(true);
        myPane.getVerticalScrollBar().setAutoscrolls(true);
        add(myPane, BorderLayout.CENTER);
        m_tree.addMouseListener(this);
          initGUI();
     private void initGUI() {
          try {
               setPreferredSize(new Dimension(400, 300));
          } catch (Exception e) {
               e.printStackTrace();
     public void mouseClicked(MouseEvent e) {
          String util = String.format("%f", 6546464642345679801234567980.00 * multi);
        util = "abc" + " (" + util  + ")";
        DefaultMutableTreeNode child = (DefaultMutableTreeNode) parent.getChildAt(0);
        child.setUserObject(util);
        m_tree.repaint();
     public void mouseEntered(MouseEvent e) {}
     public void mouseExited(MouseEvent e) {}
     public void mousePressed(MouseEvent e) {}
     public void mouseReleased(MouseEvent e) {}
class ContainerNode extends DefaultMutableTreeNode
    private static final long serialVersionUID = 14;
    ContainerNode(String s)
    { super(s); }
}Executing this code... clicking in the panel, changes the number.
The new number is displayed as (65464646423456798000000000.000.......
My problem is nearly similar, except that in my code I am using, String.format("%.2f", 6546464642345679801234567980.00 * multi);
and still I get (65...)
