让我们假设我有一个zul页面，其中我有不同的组件，如文本框，插件箱，按钮等...现在我拖放组件在这里和那里现在我想保存窗口的状态，当我再次来到同一页面所有组件的相同位置都会显示..如何在ZK Framework中完成。这是演示代码

现在如何保存窗口的新闻状态？
答案 0 :(得分：2)
所有组件都是可序列化的（java.io.Serializable）。像克隆一样，所有的孩子和后代都是连载的。如果序列化组件然后反序列化它，结果将与调用Component.clone（）相同
如果要重新绘制组件的组件调用isInvalidated()的相同状态，请保存组件。
isInvalidated
布尔isInvalidated()
返回是否需要在客户端重绘此组件。
应用程序开发人员很少需要调用此方法。
注意：
如果它不属于任何页面，它总是返回true（因为如果稍后将它附加到页面，则需要重绘）。
如果当前执行不是异步更新（因此总是需要重绘），它总是返回true。
如果其父级无效，则此组件也将重新绘制，但如果未针对此组件调用invalidate()，则此方法返回false。
