Hi,
public class SingletonEventDispatcher extends EventDispatcher
{
public static function getInstance():SingletonEventDispatcher
{
// code to return single object.
}
}
// to add a listener anywhere in the code
SingletonEventDispatcher.getInstance().addEventListener("customEvent",customEventHandler)
//to dispatch anywhere in the code
SingletonEventDispatcher.getInstance().dispatchEvent(new
Event("customEvent"));
Hope this will give you an idea, what i meant to say.
