Wicket 教程3:使用 PageView 来调试页面

使用 PageView 来调试页面.

Wicket中提供了一个PageView类,顾名思义 就是查看当前page的信息, 使用该类可以显示当前页面的所有组件.
使用方法很简单在page中加上一个markup:   <span wicket:id="componentTree"/>
然后 添加一下代码到page的构造函数中.


add(new PageView("componentTree", this));

对于 Wicket教程2 的输出信息如下:


[Page class = wicket.quickstart.Index, id = 2]:
