最近由于项目需要用到ExtJs，初次接触这个框架，特搜集相关资料，以便查阅

面板中可以有工具栏，工具栏可以位于面板顶部或底部，Ext中工具栏是由Ext.Toolbar类表示。工具栏上可以存放按钮、文本、分隔符等内容。面板对象中内置了很多实用的工具栏，可以直接通过面板的tools配置选项往面板头部加入预定义的工具栏选项。

比如下面的代码：

Ext.onReady(

function(){

new Ext.Panel({

renderTo:

"hello",

title:

"hello",

//面板标题

width:300,

height:300,

html:'<h1>Hello,HelloWorld!</h1>',

tools:[{

//生成面板右上角的工具栏

id:

"save",

handler:

function(){Ext.Msg.alert('最大化','呵呵');}

//点击工具栏调用些方法

{id:

"help", {id:

"close"}],

tbar:[

new Ext.Toolbar.TextItem('工具栏：'),

//添加一文本

{pressed:

true,text:'刷新'},

{xtype:

"tbfill"},

//加上这句，后面的就显示到右边去了

{pressed:

true,text:

"添加"},

handler:

function

(){Ext.Msg.alert('帮助','please help me!');}

{pressed:

true,text:

"保存"}

]

});
