Flex父子窗口相互调用实现思路及源码

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：

复制代码 代码如下:

xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
width="100%" height="100%">








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");
}

]]>


verticalAlign="middle" textAlign="center">

（2）子窗口

ChildWindow.mxml：

复制代码 代码如下:

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">




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);
}
}
]]>

3、设计结果

（1）初始化时
 
（2）单击修改按钮
