      Description

      Non-Java applications can produce ascii versions of dead keys by typing
      the dead key followed by the space key. For example, in a German xmodmap, dead-acute followed by space produces apostrophe. dead-circumflex followed
      by space produces ascii circumflex.

      The test case below can be used to see that this does not work in JDK1.4.2
      with lightweight TextComponents (including Swing).

      import java.awt.event.*;
      import javax.swing.*;

      public class MySwingTest extends JApplet implements KeyListener, ActionListener {

          JTextField jtf = null;
          JTextArea jta = null;

          public static void main(String[] args) {
              JFrame frame = new JFrame("MySwingTest");
              JPanel p = new JPanel();

              MySwingTest applet = new MySwingTest();
              applet.init();

              p.add("Center", applet);
              frame.getContentPane().add(p);

              frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
              frame.pack();
              frame.setSize(850, 200);
              frame.setVisible(true);

              applet.start();
          }

          public void init() {
              JLabel jl = new JLabel("Enter characters");

              jtf = new JTextField("Hello World", 20);

              jta = new JTextArea("Hello World", 4, 30);

              System.out.println(evt.toString());

          protected void printKey(KeyEvent evt)
          {
              switch(evt.getID())
              {

                " KeyCode: " + evt.getKeyCode() +
                " Modifiers: " + evt.getModifiers());
              if (evt.isActionKey())
                  System.out.print(" Action Key");
              System.out.print("\n");

              System.out.println("keyText= " + evt.getKeyText(evt.getKeyCode())
                + "\n");
