Closing JInternalFrame with ESC-Key?

Question

Hi all.
Is there a way to close JInternalFrames with the ESC-Key?
For JDialogs that works good (adding an action to the rootPane's ActionMap) but I cannot figure out how to add this functionality for JInternalFrames as well.
Any hints?
Regards
Carsten

try this
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TextButton extends JFrame
JFormattedTextField tf1;
Container con;
public TextButton()
con=getContentPane();
con.setLayout(new FlowLayout());
tf1=new JFormattedTextField();
tf1.setValue(" ");
tf1.addKeyListener(new KeyAdapter()
     public void keyPressed(KeyEvent ke)
     if(ke.getKeyCode()==10)     
System.exit(0);
con.add(tf1);
setSize(400,400);
setVisible(true);
public static void main(String args[])
new TextButton();
}
