LearningExtJS_new 之 Layout 的应用学习(五)

Ext.onReady(function(){
//1.使用布局(第一个布局)
//	1>认识布局中的几个元素 panel 小容器,region 小容器存放位置,viewport 大容器
//	2>布局中的参数 
//		@collapsible 是否可以折叠,双击时折叠
//		@collapseMode 折叠模式,出现小图标
//		@minSize 拖拉的最小宽度
//		@maxSize 拖拉的最大宽度
//		@margins 上下左右间格度
//		@cmargins 折叠时间格度
//		@bodyStyle 内容样式
//2.使用tab panel
//	1>使用tabpanel时,把原来xtype找成tabpanel(注意这里大小写敏感),增加activeTab项(可选),配置items项
//	2>增加gridPanel到对应的tab项中,增加xtype:'grid',配置对应的store和cm项
//	3>使用accordion 配置title和autoLoad()
//3.增加工具栏
//	1>类型 为toolbar,设置items选项
//4.增加form
//	1>类型 为form ,设置items选项
//5.嵌套布局	
//	1>设置 在已有的布局中,增加layout为border.配置items选项,
//	2>设置图标,ie:iconCls:'de',
//6.给viewport设置ID值
//	1>getCmp 取容器,findById,取容器中的子元素
//	2>根据需要动态增加 tabpanel
