Ext4 treepanel控件绑定事件

Question

我使用ext4进行开发时，在tree上添加事件都不能触发不知道怎么回事，网上资料都说是下面这种方式，但是不对的，哪位大虾解决下吧，谢谢了啊Ext.namespace("Xingte");Xingte.creatTree=function(){
var store = Ext.create('Ext.data.TreeStore', {
    root:{
     expanded: true, 
        text:"菜单",
        user:"",
        status:"",
        children: [
            {id:"x",text:"detention",leaf: true},
            {text:"book", leaf: true },
            {text:"alegrbra", leaf: true},
            {text: "buy", leaf:true }
        ]
    }
});

var treePanel=new Ext.tree.TreePanel({
title:'系统菜单',
region:'west',
    store:store,
    slide:true,
    split:true,
    width:200,
    collapsible:true,
    scroll:true
});



return treePanel;
};

var store = Ext.create('Ext.data.TreeStore', {
    root: {
        expanded: true, 
        text:"",
        user:"",
        status:"", 
        children: [
            { text:"detention", expanded: true,
children:[
{ leaf: true,text:'aaa'},
{ leaf: true,text:'bbb'}
]
},
            { text:"homework", expanded: true, 
                children: [
                    { leaf: true,text:'ccc'}
                ]
            },
            { text: "buy lottery tickets", leaf:true }
        ]
    }
});     var txtTreePanel=Ext.create('Ext.tree.Panel', {
    height: '100%',
    store: store,
    rootVisible: false,
listeners : {  
        itemclick : function(view,re){  
            alert(re.data.text);
        }  
    }
});

Answer 2

listeners : {  
  itemclick : function(view,re){  
  alert(re.data.text);
  }  
  }最主要的是这个监听项点击事件
