VBox vBox2 = new VBox(new Button("Button4"), new Button("Button5"), new Button("Button6"));
TitledPane titledPane2 = new TitledPane();

titledPane2.setContent(vBox2);
//默認是否展開

    public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
        System.out.println("observable = " + observable + ", oldValue = " + oldValue + ", newValue = " + newValue);
    }
});

    @Override
    public void changed(ObservableValue<? extends TitledPane> observable, TitledPane oldValue, TitledPane newValue) {
        System.out.println("observable = " + observable + ", oldValue = " + oldValue + ", newValue = " + newValue);
