最近在学习Extjs，感觉到了extjs的强大，尤其是看了它的desktop之后，ext的desktop做的确实不错，在网上找了一下extjs的desktop的资料，并没有太多完整的实例有的话想下载很麻烦，于是决定自己整一个，说干就干，我的desktop是SSH+Extjs 4实现
?
?
总体架构就是大家看到的截图，至于SSH框架的大家就不在这里赘述了，接下来介绍每个包的作用：
??? core包中存放desktop的核心代码：
???? 
? ? css包用于存放样式：
??? 
?? ext包用于存放js：
?images用于存放desktop中的图片，在extjs的desktop的例子中可以找到images包
modules中用于存放桌面上显示的模块：
?
?接下来就是把App.js 和setting.js以及desktop.html考到WebContent的目录下

目前desktop的例子就自己扩展了一个用户模块，最近由于时间紧，还没有进行下一步扩展， 不过对于学习还是可以参考的了， 由于是集成SSH所欲文件有点大无法上传， 如果有需要还是留言吧或者有微博的朋友可以加我为好友，因为微博一直在线， 可以回复的及时一些吧，微博昵称：临时工介绍所
