et voici la classe QuitDialog qu on appel si l utilisateur clic sur exit
dans le menu file
il faut la compiler dans le bin avant de compiler la classe file
Bon courage a vous.

import java.awt.*;


public class QuitDialog extends Dialog {

void yesButton_Clicked(Event event) 
            {
      //getParent().handleEvent(new Event(this, Event.WINDOW_DESTROY, null));
              System.exit(0);
            }

void noButton_Clicked(Event event) {

// Clicked from noButton Hide the Dialog
hide();

}

public QuitDialog(Frame parent, boolean modal) 
             {
        super(parent, modal);
setLayout(null);
// addNotify();
resize(insets().left + insets().right + 337,insets().top + insets().bottom + 135);
yesButton = new java.awt.Button(" Yes ");
yesButton.reshape(insets().left + 72,insets().top + 80,79,22);
