        launch( args);
    }

    private Parent getContent() {
        VBox box = new VBox(10);
        ListView list = new ListView();
        ObservableList<String> items = new ObservableListWrapper<String>(Arrays.asList("One", "Two", "Three", "Four", "Five", "Six", "long\n line\n long\n line long\n line\n long\n line"));
