How can I add the listener to the CellRenderer

Question

My class named NoteColumnRenderer extends DefaultTableCellRenderer
and thhe getTableCellRendererComponent() returns JButton .
My question is how can I add MouseMotionListener to the JButton
or how can I add MouseMotionListener to the NoteColumnRenderer ?
The code below,and there is no effect
public class NoteColumnRenderer extends DefaultTableCellRenderer {
public NoteColumnRenderer(boolean multiSelection) {
super();
System.out.println("b="+this.getListeners(MouseMotionListener.class).length);
this.addMouseMotionListener(new MouseMotionListener(){
public void mouseDragged(MouseEvent e) {
System.out.println("mouse+++++++");
public void mouseMoved(MouseEvent e) {
System.out.println("mouse-------");
m_button.addMouseMotionListener(new MouseMotionListener(){
public void mouseDragged(MouseEvent e) {
// TODO Auto-generated method stub
System.out.println("mouse=====");
public void mouseMoved(MouseEvent e) {
// TODO Auto-generated method stub
System.out.println("mouse=======");
System.out.println("a="+this.getListeners(MouseMotionListener.class).length);
m_multiSelection = multiSelection;
if (m_multiSelection) {
     m_check = new JCheckBox();
m_check.setMargin(new Insets(0, 0, 0, 0));
m_check.setHorizontalAlignment(JLabel.CENTER);
          } else
m_button.setMargin(new Insets(0, 0, 0, 0));
m_button.setSize(new Dimension(5, 5));
m_combobox = new JComboBox();
     } // IDColumnRenderer
     /** Mult-Selection flag */
     private boolean m_multiSelection;
     /** The Single-Selection renderer */
     private JButton m_button=new JButton();
     /* The Multi-Selection renderer */
     private JCheckBox m_check;
     private JComboBox m_combobox;
     protected void setValue(Object value) {
          if (m_multiSelection) {
               boolean sel = false;
               if (value == null)
     else if (value instanceof Boolean)
          sel = ((Boolean) value).booleanValue();
               else
          sel = value.toString().equals("Y");
               m_check.setSelected(sel);
          else
               if (value == null)
               else
     if(value.toString().length()>10)
m_button.setText(value.toString().substring(0,10)+"...");
                    else
                         m_button.setText(value.toString());
                    m_button.setBackground(Color.WHITE);
     public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
          setValue(value);
          if (m_multiSelection)
               return m_check;
          else
               return m_button;
}

Listener can be added to a cell editor, not cell renderer.
Set relevent cess(s) to setEditable == true when you use your custom cell editor.
