Hm, I am doing something similar in some item renderers (Have in mind
that there might be an easier / better way i am still learning this):
I can think of two ways
1) (simple and dirty):
Register the callback and in the callback call a function on the other
component that you are interested:
a) Component A throws Alert with callback A
b) callback a calls (component B).alertClosed(some var here if needed)
2) Generic / better ? way (not sure if it any better actually :-)
a) Create a new event class ie:
package events
{
import flash.events.Event;
public class DeletePhotoEvent extends Event
{
public var photoId:String ;
public function DeletePhotoEvent (type:String,
bubbles:Boolean=false, cancelable:Boolean=false)
{
super(type, bubbles, cancelable);
}
// Override the inherited clone() method.
override public function clone():Event
{
return new DeletePhotoEvent (type);
}
}
}
b) Make your component - the one with the alert register this type of
event (TileList example):
<mx:TileList xmlns:mx="http://www.adobe.com/2006/mxml";
direction="horizontal">
<mx:Metadata>
[Event(name="deletePhotoEvent",
type="events.DeletePhotoEvent")]
</mx:Metadata>
</mx:TileList>
c) associate this callback with your component b method
<ns1:UserPhotos id="rightPanelId"
deletePhotoEvent="componentB.alertClosed()"/>
*) you will still need the callback in component A:
private function deleteMe(event:MouseEvent):void
{
var delPhotoEv:DeletePhotoEvent = new
DeletePhotoEvent("deleteProductEvent", true) ;
delPhotoEv.photoId = event.currentTarget.value ;
dispatchEvent(delPhotoEv);// bubble to parent
}
Hope it helps ;-)
