flex中创建弹出窗口，并传值

在flex页面中首先创建一个弹出窗口，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"
               title="title" horizontalCenter="0" verticalCenter="0" backgroundColor="white"
               chromeColor="#5CACEE" close = "removeWindow()" cornerRadius="5"
               width="600" height="440" creationComplete="init()">
    <fx:Declarations>
    </fx:Declarations>
    <fx:Style>

        @namespace s "library://ns.adobe.com/flex/spark";
        @namespace mx "library://ns.adobe.com/flex/mx";
        @namespace component "com.xyw.sys.custom.component.*";
        @namespace skin "com.xyw.sys.custom.skin.*";
        .myLabel
        {
            fontStyle:italic;
            fontWeight:bold;
            color:#A020F0;
            fontFamily:微软雅黑;
        }

    </fx:Style>
    <fx:Script>
        <![CDATA[import com.model.VD3;import mx.collections.ArrayCollection;
            import mx.collections.ArrayList;
            import mx.controls.Alert;
            import mx.controls.DateField;
            import mx.managers.PopUpManager;import mx.rpc.events.ResultEvent;

            public var cerDataGrid:ArrayCollection;
            public var vd3:VD3;
            private function init():void
            {
                //init your function
            }
            private function removeWindow():void
            {
                PopUpManager.removePopUp(this);
            }
        ]]>
    </fx:Script>
</s:TitleWindow>

2.然后在主页面中调用它：用到如下函数

 public function myFunction(event:MouseEvent):void
             {
                 if(this.vD3 == null){
                     Alert.show("请选择要操作的行");
                     return;
                 }else{
                     var window:detial = new detial();
                     window.vd3 = this.vD3;// 要传入的model
                     PopUpManager.addPopUp(window,this);
                     var x:Number = (this.parentApplication.mdiCanvas.width - window.width) / 2;
                     var y:Number = (this.parentApplication.mdiCanvas.height - window.height) / 2;
                     window.move(x, y);
                 }
             }

3.主页面中要传入的值若是查询数据的一行，则可以转化为一个model，如下（VD3类似于java的model）

 private function onSelected(event:GridSelectionEvent):void
             {
                 this.vD3 = DataGrid(event.target).selectedItem as VD3;
             }
