用swing的朋友很多，但是用到swingX的可能就不那么多了。
官方对swingX的解释如下:
SwingX is all about Swing components. It focuses both on extensions to existing Swing components as well as brand new ones. SwingX contains a lot of great components that you can use in your applications today.
也就是说swingX是一个包含swing组建的容器，它扩展了swing容器并对其有所更新，SwingX包含了大量你可能应用到的组件～
