jsf - 扩展 Richfaces 组件 - 例如为特定实现自定义 Datatable 组件

Question

如何扩展 Richfaces 组件的功能，例如具有自定义标题和排序技术的数据表。我看过扩展数据表，但没有从中得到太多信息。如果可用，请指点我一个例子。

谢谢

Well, you can extend a JSF component with the regular java extension (extends). You will have to extend a number of classes, depending on the exact component:

• UIComponentName/HtmlComponentName
• HtmlComponentNameRenderer
• ComponentNameTag

and you might need to register the renderer in faces-config.xml.

You can take a look at this thread, or google for "Extend JSF component" or "Create custom JSF component".
