FLEX: How to know when a dialog created throw PopUpManager Closes

Question

Is there a easy way to figure out consistently when a Dialog closes that has been created through PopUpManager. I would have suspected some type of message or callback mechanism, but there does not seem to be. In one case I use the WindowTitle component and event that only fires the CLOSE if someone presses the close and give no message when the dialog actually closes.

Not sure if this is the solution to all needs. But, if you're using a TitleWindow, just listen to the close event:

Something like this:

var win : IFlexDisplayObject = PopUpManager.createPopUp(Application.application as DisplayObject, TitleWindow, false) as IFlexDisplayObject;
win.addEventListener(CloseEvent.CLOSE, onClose);
PopUpManager.centerPopUp(win);

And the title window should be something like this:

<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" showCloseButton="true" close="closeHandler(event)">
<mx:Script>
    <![CDATA[
        import mx.events.CloseEvent;
        import mx.managers.PopUpManager;

        protected function closeHandler(event:CloseEvent):void
        {
            PopUpManager.removePopUp(this);
        }           
    ]]>
</mx:Script></mx:TitleWindow>
