Hi! I'm writing down a simple itemRender with a single peculiarity: if
you have a mouseOver event on a entry of the list using this
itemRenderer it is shown a button so you can delete that entry.
This is the code:

<?xml version="1.0" encoding="utf-8"?>
<mx:HBox mouseOver="showButton(event)" mouseOut="hideButton(event)"
xmlns:mx="http://www.adobe.com/2006/mxml"; >

        <mx:Script>
                <![CDATA[

                        public static const DELETE:String = "Delete";

                        private function showButton(event:Event = null):void
                        {
                                but.visible = true;
                        }

                        private function hideButton(event:Event = null):void
                        {
                                but.visible = false;
                        }

                        private function sendMessage(event:Event = null):void
                        {
                                this.dispatchEvent( new Event( DELETE ) );
                        }
                ]]>
        </mx:Script>

        <mx:Label text="{data.network_id}" />
        <mx:Button id="but" click="sendMessage(event)" visible="false"
label="X" />

</mx:HBox>

Now, how can I listen to that event from the List using this item
renderer?
