1、设计思路

（1）新建一个DataGrid，在其中最后一列加入三个按钮：新增、修改和删除；

（2）点击新增按钮，可以将表格新增一行；

（3）单击“修改”按钮，可以修改表格中该行的一些属性；

（4）单击“删除”按钮，会将表格中该行删除。

2、实现步骤

（1）新建一个应用程序，DataGrid.mxml

DataGrid.mxml：

复制代码 代码如下:

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

<s:layout>

<s:BasicLayout/>

</s:layout>

<fx:Declarations>

<>

</fx:Declarations>

<fx:Script>

<![CDATA[

import mx.collections.ArrayCollection;

[Bindable]

//表格数据源绑定

private var grid:ArrayCollection = new ArrayCollection([

{number:"2014010101",name:"张三",sex:"男",age:"19"},

{number:"2014010102",name:"李思",sex:"女",age:"20"},

{number:"2014010103",name:"蔡华",sex:"男",age:"21"},

{number:"2014010104",name:"牛耳",sex:"女",age:"22"},

{number:"2014010105",name:"兆司",sex:"男",age:"18"},

{number:"2014010106",name:"胡柳",sex:"女",age:"19"},

{number:"2014010107",name:"刘斯",sex:"男",age:"20"},

{number:"2014010108",name:"孙阳",sex:"女",age:"22"},

{number:"2014010109",name:"郑武",sex:"男",age:"21"},

{number:"2014010110",name:"王雪",sex:"女",age:"20"},

{number:"2014010111",name:"胡柳",sex:"女",age:"19"},

{number:"2014010112",name:"刘斯",sex:"男",age:"20"},

{number:"2014010113",name:"孙阳",sex:"女",age:"22"},

{number:"2014010114",name:"郑武",sex:"男",age:"21"},

{number:"2014010115",name:"王雪",sex:"女",age:"20"}

]);

</fx:Script>

<mx:VBox width="100%" height="100%" paddingBottom="100" paddingLeft="100" paddingRight="100" paddingTop="100">

<mx:HBox width="100%" paddingLeft="40">

<![CDATA[

import mx.managers.PopUpManager;

/*添加按钮事件函数*/

protected function addHandler(event:MouseEvent):void

{

var childWindow:ChildWindow = ChildWindow(PopUpManager.createPopUp(this,ChildWindow,true));

var point:Point = new Point(100,100);

childWindow.x = point.x + 400;

}

</fx:Script>

<mx:LinkButton label="新增" click="addHandler(event)"/>

<s:Label width="10"/>

<mx:LinkButton label="修改" click="updateHandler(event)"/>

<s:Label width="10"/>

<mx:LinkButton label="删除"/>

</mx:HBox>

</fx:Component>

</mx:itemRenderer>

</mx:DataGridColumn>

</mx:columns>

</mx:DataGrid>

</mx:VBox>

</s:Application>

（2）新建一个新增窗口组件，ChildWindow.mxml

ChildWindow.mxml：

复制代码 代码如下:

<?xml version="1.0" encoding="utf-8"?>

<s:TitleWindow xmlns:fx="http://ns.adobe.com/mxml/2009"

xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300"

close="closeHandler(event)" title="新增窗口">

<s:layout>

<s:BasicLayout/>

</s:layout>

<fx:Script>

<![CDATA[

import mx.events.CloseEvent;

import mx.managers.PopUpManager;

/*关闭按钮函数*/

protected function closeHandler(event:CloseEvent):void

{

PopUpManager.removePopUp(this);

}

/*取消按钮函数*/

protected function cancelHandler(event:MouseEvent):void

{

PopUpManager.removePopUp(this);

}

]]>

</fx:Script>

<fx:Declarations>

<>

</fx:Declarations>

<mx:VBox width="100%" height="100%" horizontalAlign="center">

<mx:Form border borderColor="#CCCCCC" width="100%">

<mx:FormHeading label="新增界面" fontSize="14"/>

<mx:FormItem label="学号：">

<s:TextInput id="stuNo" width="200"/>

</mx:FormItem>

<mx:FormItem label="姓名：">

<s:TextInput id="stuName" width="200"/>

</mx:FormItem>

<mx:FormItem label="性别：">

<s:TextInput id="stuSex" width="200"/>

</mx:FormItem>

<mx:FormItem label="年龄：">

<s:TextInput id="stuAge" width="200"/>

</mx:FormItem>

</mx:Form>

<mx:HBox width="100%" height="25">

<s:Label width="60"/>

<s:Button label="新增"/>

<s:Label width="48"/>

<s:Button label="取消" click="cancelHandler(event)"/>

</mx:HBox>

</mx:VBox>

</s:TitleWindow>

（3）新建一个修改界面组件，UpdateWindow.mxml

UpdateWindow.mxml：

复制代码 代码如下:

<?xml version="1.0" encoding="utf-8"?>

<s:TitleWindow xmlns:fx="http://ns.adobe.com/mxml/2009"

xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300"

close="closeHandler(event)" title="修改窗口">

<s:layout>

<s:BasicLayout/>

</s:layout>

<fx:Script>

<![CDATA[

import mx.events.CloseEvent;

import mx.managers.PopUpManager;

/*关闭按钮函数*/

protected function closeHandler(event:CloseEvent):void

{

PopUpManager.removePopUp(this);

}

/*取消按钮函数*/

protected function cancelHandler(event:MouseEvent):void

{

PopUpManager.removePopUp(this);

}

]]>

</fx:Script>

<fx:Declarations>

<>

</fx:Declarations>

<mx:VBox width="100%" height="100%" horizontalAlign="center">

<mx:Form border borderColor="#CCCCCC" width="100%">

<mx:FormHeading label="修改界面" fontSize="14"/>

<mx:FormItem label="学号：">

<s:TextInput id="stuNo" width="200"/>

</mx:FormItem>

<mx:FormItem label="姓名：">

<s:TextInput id="stuName" width="200"/>

</mx:FormItem>

<mx:FormItem label="性别：">

<s:TextInput id="stuSex" width="200"/>

<s:Button label="修改"/>

<s:Label width="48"/>

<s:Button label="取消" click="cancelHandler(event)"/>
