         // formatting relevant to the current locale. This would format
         // 43.68 as "$43.68", and -23.67 as "-$23.67"

         // change the text fill based on whether it is positive (green)
         // or negative (red). If the cell is selected, the text will
         // always be white (so that it can be read against the blue
         // background), and if the value is zero, we'll make it black.
         if (item != null) {
             double value = item.doubleValue();
             setTextFill(isSelected() ? Color.WHITE :
                 value == 0 ? Color.BLACK :

This class could then be used inside a ListView as such:
 ObservableList<Number> money = ...;
 final ListView<Number> listView = new ListView<Number>(money);
 listView.setCellFactory(new Callback<ListView<Number>, ListCell<Number>>() {
     @Override public ListCell<Number> call(ListView<Number> list) {
         return new MoneyFormatCell();
     }
 });
