flex: how to Make two resize effect at the same time

Hy,

Is it possible to resize the application at the same moment when the Accordion size change, to make effect resize og the last one synchronised with re开发者_如何学Gosize of Application ?

In my code,, the Application is resized after the resize of Accordion is completed:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
                layout="absolute" minWidth="400" minHeight="300" backgroundColor="white" horizontalScrollPolicy="off" verticalScrollPolicy="off" mouseDown="stage.nativeWindow.startMove()">



    <mx:Resize id="expand" target="{application}" heightTo="{acc01.height}"/>
    <mx:Accordion id="acc01" x="0" y="0" resizeToContent="true" resize="expand.play();" horizontalScrollPolicy="off" verticalScrollPolicy="off">
        <mx:VBox label="Accordion Pane 1" width="100%" height="100%">            
            <mx:Label text="hello"/>
            <mx:Label text="hello"/>
            <mx:Label text="hello"/>
            <mx:Label text="hello"/>
        </mx:VBox>
        <mx:VBox label="Panel 2" width="100%" height="100%">
            <mx:Label text="hello"/>
            <mx:Label text="hello"/>
        </mx:VBox>
        <mx:VBox label="Panel 3" width="100%" height="100%">
               <mx:Label text="hello"/>
            <mx:Label text="hello"/>
        </mx:VBox>
        <mx:VBox label="Panel 4" width="100%" height="100%">
               <mx:Label text="hello"/>
            <mx:Label text="hello"/>
        </mx:VBox>
    </mx:Accordion>
</mx:Application>
