现在x l历了三个阶D?/span>
刚开始是demo阶段Q因Z知道路走不走的通，全面摸烦GXT能实现的效果Q也没注意模块的规划Q甚臛_一个类
而后发现q是能走通的Q就开始添砖加瓦，发现代码加ؕQ决心重构，定义了多个包Q多个类负责不同的功能模块，定义了一些PanelQ一下子清晰多了Q也遇到了不同模块间互相调用的问题，自己惛_然的办法是在一个类中声明每个模块作为属性，像一个ȝQ每个屋子的钥匙我都有了Q也认识Cq样的缺点，一些模块中的事件不{不在这个主中定义
现在NowQ用一天时间再ơ改写，仿照Gxt中的例子Explorer
1、将各个模块定义成com.extjs.gxt.ui.client.mvc.ViewQView中必d现方法handleEvent(AppEvent event)Q负责处理发l自q事g
2、ؓ每个View定义com.extjs.gxt.ui.client.mvc.ControllerQ每个Controller中包含ViewQ在q里定义View要处理的事g
3、在Dispatcher中注册每个Controller
q样Q每个View各司其职Q他们各自有各自的功能，会接收ؓ他们定义的所有事件ƈ处理Q发送事件Dispatcher.forwardEvent(appEvent);
感觉q次改写?速度q没有改写前的快Q现在每ơ操作url会自动添加HashQ想把它LQ一直没扑ֈ根结

Servlet mapping是不是对应，
