    DecimalFormat format = new DecimalFormat("#,###.###");
    format.setGroupingUsed(true);
    format.setGroupingSize(3);
    format.setParseIntegerOnly(false);

    JFrame f = new JFrame("Numeric Text Field Example");
    final NumericTextField tf = new NumericTextField(10, format);

    tf.setValue((double) 123456.789);

    JLabel lbl = new JLabel("Type a number: ");
    f.getContentPane().add(tf, "East");
