1、设计思路

(1)子窗口调用父窗口的方法

(2)子窗口做了修改后,返回父窗口,父窗口调用子窗口函数


2、设计源码

(1)父窗口

ParentWindow.mxml:
<?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" 
width="100%" height="100%"> 
<s:layout> 
<s:BasicLayout/> 
</s:layout> 
<fx:Declarations> 
<!-- 将非可视元素(例如服务、值对象)放在此处 --> 
</fx:Declarations> 

<fx:Script> 
<![CDATA[ 
import mx.collections.ArrayCollection; 
import mx.controls.Alert; 
import mx.managers.PopUpManager; 

[Bindable] 
//表格数据源绑定 
private var grid:ArrayCollection = new ArrayCollection([ 
{number:"2014010101",name:"张散",sex:"男",age:"23"}, 
{number:"2014010102",name:"李思",sex:"女",age:"22"}, 
{number:"2014010101",name:"吴王",sex:"男",age:"21"}, 
{number:"2014010101",name:"赵柳",sex:"女",age:"20"}, 
{number:"2014010101",name:"游华",sex:"男",age:"22"}, 
{number:"2014010101",name:"祝思",sex:"女",age:"18"}, 
{number:"2014010101",name:"周礼",sex:"男",age:"19"}, 
{number:"2014010101",name:"华捷",sex:"女",age:"20"}, 
{number:"2014010101",name:"刘亮",sex:"男",age:"22"}, 
{number:"2014010101",name:"沈雪",sex:"女",age:"21"} 
]); 

/*修改事件函数*/ 
protected function updateHandler(event:MouseEvent):void 
{ 
//新建子窗体对象 
var childWindow:ChildWindow = new ChildWindow(); 
//将子窗体添加到PopUpManager中 
PopUpManager.addPopUp(childWindow,this,true); 
//向子窗体传递参数 
childWindow.age = "23"; 
//子窗口调用父窗口函数 
childWindow.callBack = this.myFunction; 
//子窗体居中弹出 
PopUpManager.centerPopUp(childWindow); 
} 

/*刷新函数*/ 
public function myFunction(you:String):void 
{ 
Alert.show(you+"Hello"); 
} 

]]> 
</fx:Script> 
<mx:VBox width="100%" height="100%" paddingBottom="10" paddingLeft="10" paddingRight="10" paddingTop="10"> 
<mx:DataGrid id="dataGrid" dataProvider="{grid}" rowCount="{grid.length + 1}" width="100%" 
verticalAlign="middle" textAlign="center"> 
<mx:columns> 
<mx:DataGridColumn headerText="学号" dataField="number"/> 
<mx:DataGridColumn headerText="姓名" dataField="name"/> 
<mx:DataGridColumn headerText="性别" dataField="sex"/> 
<mx:DataGridColumn headerText="年龄" dataField="age"/> 
</mx:columns> 
</mx:DataGrid> 
<mx:HBox width="100%" horizontalAlign="center" verticalAlign="middle"> 
<s:Button label="修改" click="updateHandler(event)"/> 
</mx:HBox> 
</mx:VBox> 
</s:Application>

(2)子窗口

ChildWindow.mxml:

<?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="300" height="220" 
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; 

//回调函数 
public var callBack:Function; 

public var age:String = ""; 

/*关闭事件函数*/ 
protected function closeHandler(event:CloseEvent):void 
{ 
PopUpManager.removePopUp(this); 
} 

/*修改按钮事件函数*/ 
protected function updateHandler(event:MouseEvent):void 
{ 
stuAge.text = age; 
} 

/*取消按钮事件函数*/ 
protected function cancelHandler(event:MouseEvent):void 
{ 
number.text = ""; 
stuName.text = ""; 
PopUpManager.removePopUp(this); 
if(isPopUp) 
{ 
callBack.call(parent); 
} 
} 
]]> 
</fx:Script> 
<fx:Declarations> 
<!-- 将非可视元素(例如服务、值对象)放在此处 --> 
</fx:Declarations> 

<mx:VBox width="100%" height="100%"> 
<mx:Form> 
<mx:FormItem label="学号:"> 
<s:TextInput id="number" width="200" maxChars="10"/> 
</mx:FormItem> 
<mx:FormItem label="姓名:"> 
<s:TextInput id="stuName" width="200" maxChars="10"/> 
</mx:FormItem> 
<mx:FormItem label="性别:"> 
<mx:HBox width="100%"> 
<mx:RadioButtonGroup id="sex"/> 
<s:RadioButton groupName="sex" label="男" selected="true"/> 
<s:RadioButton groupName="sex" label="女"/> 
</mx:HBox> 
</mx:FormItem> 
<mx:FormItem label="年龄:"> 
<s:TextInput id="stuAge" width="200" maxChars="2"/> 
</mx:FormItem> 
<mx:FormItem> 
<mx:HBox width="100%"> 
<s:Button label="修改" click="updateHandler(event)"/> 
<s:Label width="42"/> 
<s:Button label="取消" click="cancelHandler(event)"/> 
</mx:HBox> 
</mx:FormItem> 
</mx:Form> 
</mx:VBox> 
</s:TitleWindow>
