Thanks yet again Tracy for helping me along on my steep learning curve with this Flex malarkey.

Yes, the "evt_obj" target or currentTarget has a reference to the custom component. Have a getter function in the component return the name. I also advise passing in the entire item. It cleans up the code and provides flexibility when you decide you need some other bit of item data in the component or in the handler. See below. Tracy Goal: Display a list of items using a complex display for each item, and have each of those items behave like a menu element and respond to a click anywhere on the item by running a handler function. One solution is to use a Repeater with a custom component In the main app or component, declare the Repeater, and the click handler function. <mx:Application ... <mx:Script><![CDATA[ import MyRepeaterItem; ... private function onRPItemClick(oEvent:Event):void { var xmlItem:XML = XML(oEvent.target); }//onRPItemClick ]]></mx:Script> <mx:VBox ...> <mx:Repeater id="rp" dataProvider="{_xmlData}" ...> <!-- Note we pass in the entire currentItem, and define a click handler --> <MyRepeaterItem xmlItem="{rp.currentItem}" itemClick="onRPItemClick(event)" .../> </mx:Repeater </mx:VBox> </mx:Application> And in the component, MyRepeaterItem.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:HBox mouseChildren="false" buttonMode="true" click="onClick(event)" > <!-- The metadata tag below allows us to define an itemClick handler in mxml, as in the code above --> <mx:Metadata> [Event(name="itemClick", type="flash.events.Event")] </mx:Metadata> <mx:Script><![CDATA[ [Bindable]private var _xmlItem:XML; /** Setter function */ public function set xmlItem(xml:XML):void { _xmlItem = xml; //do any special, non-bound ui stuff you want }//set xmlItem /** Getter function */ public function get xmlItem():XML { return _xmlItem; }//get xmlItem /** Outer VBox Click handler function */ private function onClick():void { dispatchEvent(new Event("itemClick",false); //we do not need/want this event to bubble }//onClick ]]></mx:Script> <!-- Now declare the Item UI --> <mx:Text id="lbDescription" text="[EMAIL PROTECTED]" width="100%" height="100%" /> </mx:HBox> ________________________________________ From: flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> [mailto:flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> ] On Behalf Of Paul Steven Sent: Thursday, September 06, 2007 2:36 AM To: flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> Subject: [flexcoders] How do I get a property from a custom component?
