[flexcoders] Bind a property of an ActionScript generated component

[vixiom]

Is it possible to bind an ActionScript generated component's properties?

In the example below 'sq1' will move when the browser is resized but
'sq2' won't.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute" creationComplete="onCreationComplete()">
        <mx:Script>
                <![CDATA[
                        public function onCreationComplete():void
                        {
                                var sq2:Canvas = new Canvas();
                                sq2.width = 10;
                                sq2.height = 10;
                                sq2.setStyle("backgroundColor", "#999999");
                                container.addChild(sq2);
                                sq2.x = container.width / 4;
                                sq2.y = 100;
                        }
                ]]>
        </mx:Script>
        <mx:Canvas id="container" width="100%" height="150"
backgroundColor="#ffffff">
                <mx:Canvas id="sq1" width="10" height="10" x="{container.width 
/ 4}"
y="50" backgroundColor="#000000"/>
        </mx:Canvas>
</mx:Application>
