皮肤:ClassReference(null) 将不起作用；使用下面的工作

upSkin: ClassReference(null);
overSkin: ClassReference(null);
downSkin: ClassReference(null);
disabledSkin: ClassReference(null);
selectedUpSkin:ClassReference(null);
selectedOverSkin: ClassReference(null);
selectedDownSkin: ClassReference(null);
selectedDisabledSkin: ClassReference(null);
