I'm not sure you need to develop a class to do that.

You have to consume the event.

No it wasn't ;^)

Here is an example:
TextField t = new TextField();
t.addKeyListener(new KeyAdapter() {
  public void keyTyped(KeyEvent e) {
    char c = e.getKeyChar();
    if (!Character.isDigit(c)) {e.consume;}
  }
});

Hope that helps,
