[flexcoders] Using an Alert when handling another event?

[lanekelly5]

I'm using a SuperTabNavigator control from the flexlib package.  When 
the user clicks on the close button for a tab it fires the tabClose 
event.  I have specified a handler for this in the mxml for the 
SuperTabNavigator component:

tabClose="confirmTabDelete(event);"

In the confirmTabDelete function I would like to pop up an Alert with 
YES | NO buttons.  According to the SuperTabNavigator docs I can 
cancel the delete action by calling event.preventDefault() within the 
confirmTabDelete function.  My problem is that the Alert box uses its 
own handler function for the YES/NO button clicks.  I'm not sure how 
that handler function can reference the event object to call 
preventDefault().

private function confirmTabDelete(event:SuperTabEvent):void {
   Alert.show("Are you sure you want to delete this tab?", "Confirm 
delete", Alert.YES | Alert.NO, this, alertListener, null, Alert.NO);
                                
}

private function alertListener(eventObj:CloseEvent):void {
   if (eventObj.detail==Alert.NO) {
       //Now what?  How to call preventDefault() on the event object 
in confirmTabDelete?
   }
}

Is the secret in the "this" which is being used as the parent for the 
Alert?  

Any help would be great.
