Ext.ux.LightTabPanel.superclass.constructor.call(this, {
id : this.panelId,
title : this.treeNode.text,
layout : 'border',
closable : true,
autoScroll : true,
width: '100%',
height: '100%',
html: '<iframe width=100% height=100% src="
http://192.168.1.5:8080/ord?file:^html/access/employee.htm" />'
});
在面板的构造方法中这样写，就可以了
