<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" width="100%" height="100%" horizontalAlign="left" verticalAlign="middle">
    <mx:Script>
        <![CDATA[
            import mx.events.FlexMouseEvent;
            import MyPopUpWindow;
            import mx.events.FlexEvent;
            import mx.managers.PopUpManager;
            private var popup:MyPopUpWindow;
            [Bindable]
            public var str:String ;
            private function openPopUpWindow():void {
                popup = PopUpManager.createPopUp(this,MyPopUpWindow,true) as MyPopUpWindow;
                str = kkk.text;
                PopUpManager.centerPopUp(popup);
        ]]>
    </mx:Script>
    <mx:Canvas width="288" height="177">
       <mx:HBox id="jai">
