JTabbedPane detect close tab event.

Question

How can I get a title of tab which user just close (in JTabbedPane)?? I tried ContainerListener and componentRemoved method, but I can't get appropriate String with title.
Any ideas?

One way is to use a change listener:
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTabbedPane;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
public class GetDeletedTab
  private static JTabbedPane tabbedPane = new JTabbedPane();
  private static String[] workDays =
    "Monday", "Tuesday", "Wednesday", "Thursday", "Friday"
  private static int currentIndex = -1;
  private static int previousIndex = -1;
  private static void createAndShowUI()
    for (String day : workDays)
      tabbedPane.addTab(day, new JPanel());
    currentIndex = tabbedPane.getSelectedIndex();
    tabbedPane.addChangeListener(new ChangeListener()
      public void stateChanged(ChangeEvent e)
        int index = tabbedPane.getSelectedIndex();
        if (index != currentIndex)
          previousIndex = currentIndex;
          currentIndex = index;
          if (previousIndex != -1)
            String currTabTitle = tabbedPane.getTitleAt(currentIndex);
            String prevTabTitle = tabbedPane.getTitleAt(previousIndex);
            System.out.println("Previous Tab Title was: " + prevTabTitle );
            System.out.println("Current Tab Title is: " + currTabTitle);
            System.out.println();
    JFrame frame = new JFrame("GetDeletedTab");
    JPanel cPane = (JPanel)frame.getContentPane();
    cPane.setPreferredSize(new Dimension(600, 400));
    cPane.add(tabbedPane);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.pack();
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);
  public static void main(String[] args)
    java.awt.EventQueue.invokeLater(new Runnable()
      public void run()
        createAndShowUI();
}
