Ext.Panel 问题

Question

我设置了好几个title
如下
tems: [
       
        {
            title: "电子邮件",
            iconCls: 'toolEmail',
            items: [{ xtype: 'box', el: 'dv_Mail' }, mainMenuMailTree]
        },
       
   
        
        {
            title: "主菜单",
            iconCls: 'toolNav',
            items: mainMenuTree,
            tools: [{
                id: 'up',
                handler: function(e, toolEl, panel) {
                    mainMenuTree.root.collapse(true, true);
                }
            }, { id: 'down',
                handler: function(e, toolEl, panel) {
                    mainMenuTree.root.expand(true, true);
                }
            }
            ]
        },  {
            title: "在线聊天",
            iconCls: 'toolTall',
            items: [{
                xtype: 'box',
                el: 'divChat'
            }
            ]
        }, {
            title: "控制面板",
            iconCls: 'toolSetting',
            items: mainMenucontrolTree,
            tools: [{
                id: 'up',
                handler: function(e, toolEl, panel) {
                    mainMenucontrolTree.root.collapse(true, true);
                }
            }, { id: 'down',
                handler: function(e, toolEl, panel) {
                    mainMenucontrolTree.root.expand(true, true);
                }
            }
            ]我现在 想根据条件 隐藏（展现）某条title 怎么搞？网上资料太少了 请各位赐教！

Answer 1

不好意思上面的回复的错的，
tabpanel.activate(Ext.getCmp('id')) id是你要展现某条title的id 
你看看这样是否可以实现

Answer 2

你这个是tabpanel吧。这样布局的话只能remove掉

Answer 3

可以remove某一个tab看一下api的remove(obj/index)方法// 参数可以索引也可以是对象
