1:边框布局--BorderLayout

     Ext.layout.BorderLayout对应面板布局layout配置项的名称为border。该布局包含多个字面板,是一个面向应用的UI风格的布局,它将整个容器分为5个部分,

分别是east, south, west, north, center, 加入到容器中的字面板需要指定region配置项来告知容器需要加入到哪个部分,并且该布局还内建了对面板分割栏的支持。

代码:

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

  注意:BorderLayout具有固定性,渲染之后就不会任意变动或者改变格局,中央区域(center region)在BorderLayout设定中不可获缺,假使没有其他区域,

中央布局就是该布局的全部区域
