  public NumberTextField() {

  }
  // inner class to handle key events
    class KeyWatch extends KeyAdapter {
    public void keyTyped(KeyEvent e) {
      int keyNum =  e.getKeyChar();
      if(( keyNum > 32)&& (keyNum < 45)) {
      // Stop regular character from appearing:
      e.consume();
        }
      else if(( keyNum > 57)&& (keyNum < 127)) {
      // Stop regular character from appearing:
      e.consume();
        }
