For a start you are going to need a constructor. You will also need
member properties for the items you want to add to the event..
package events
{
import flash.events.Event;
public class recordEvent extends Event
{
public static const RECORD_EVENT:String = "recordEvent";
public var record:myRecordObject;
public var action:String;
public function recordEvent(type:String, record:myRecordObject,
action:String, bubbles:Boolean=true, cancelable:Boolean=true)
//Constructor
{
super(type);
this.record = record;
this.action = action;
}
override public function clone():Event
{
return new recordEvent(type, record, action, bubbles,
cancelable);
}
}
}
For a new event of your type...
dispatchEvent(new recordEvent(recordEvent.RECORD_EVENT, myRecord,
"delete"));
And for an eventListener you can use...
addEventListener(recordEvent.RECORD_EVENT, onRecordEvent);
private function onRecordEvent(event:recordEvent):void
{
var action:String = event.action;
var record:myRecordObject = event.record;
}
NB: Typed off the top of my head so may have mistakes. Generally, I
would use private member variables with getters and setters but this
should give you a starting point.
