How to catch cancel of editing in JTable?

Question

Hi.
I have JTable and I'd like to do something (like to show some warning) when user cancel editing in table cell by pressing Esc key. I suppose, that this can be done with CellEditorListener and it's method cancelEditing(). But when I use this, after pressing Esc, cancelEditing is not called.
Should I use some other listener, or am I doing something wrong with CellEditorListener?
Thanks for reply.
The code I'm trying to use
import javax.swing.DefaultCellEditor;
import javax.swing.JFrame;
import javax.swing.JTable;
import javax.swing.JTextField;
import javax.swing.event.CellEditorListener;
import javax.swing.event.ChangeEvent;
import javax.swing.table.TableCellEditor;
public class TableTest extends JFrame implements CellEditorListener {
     private JTable table = null;
     public TableTest() {
          String[] headers = {"h1","h2"};
          String [][] data = {{"x","y"}, {"y", "z"}};
          table = new JTable(data, headers);
         TableCellEditor cellEditor = new DefaultCellEditor(new JTextField());
         cellEditor.addCellEditorListener(this);
         table.getColumnModel().getColumn(0).setCellEditor(cellEditor);
          this.setContentPane(table);
     public static void main(String[] args) {
          TableTest frame = new TableTest();
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.pack();
          frame.setVisible(true);
     public void editingCanceled(ChangeEvent arg0) {
          System.out.println("Canceled");
     public void editingStopped(ChangeEvent arg0) {
          System.out.println("Stopped");
}

by default cancel of editing got catched by tab key, if u need the same with Esc key add the KeyListerner to u'r textfield u will find the solution. so i modified u'r code slightly, to get a solution.import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import javax.swing.DefaultCellEditor;
import javax.swing.JFrame;
import javax.swing.JTable;
import javax.swing.JTextField;
import javax.swing.event.CellEditorListener;
import javax.swing.event.ChangeEvent;
import javax.swing.table.TableCellEditor;
public class TableTest extends JFrame implements CellEditorListener {
     private JTable table = null;
     public TableTest() {
          String[] headers = {"h1","h2"};
          String [][] data = {{"x","y"}, {"y", "z"}};
          table = new JTable(data, headers);
          JTextField txtName = new JTextField();
          txtName.addKeyListener(new KeyAdapter(){
               public void keyPressed(KeyEvent e){
                    if(e.getKeyCode() == KeyEvent.VK_ESCAPE){
                         System.out.println("Warning or error msg");
         TableCellEditor cellEditor = new DefaultCellEditor(txtName);
         cellEditor.addCellEditorListener(this);
         table.getColumnModel().getColumn(0).setCellEditor(cellEditor);
          this.setContentPane(table);
     public static void main(String[] args) {
          TableTest frame = new TableTest();
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.pack();
          frame.setVisible(true);
     public void editingCanceled(ChangeEvent arg0) {
          System.out.println("Canceled");
     public void editingStopped(ChangeEvent arg0) {
          System.out.println("Stopped : ");
}
