Question

I know how to use addEventListener for one class to react to another class’s button being clicked on. What if you want to use it for a more general purpose than that? What if you want to use it to react to one of the member functions of the other class being called? Is there a syntax for that? Thanks!

Edit: Please note that I have already Googled for the answer.

Answer 1

You can create your own events and dispatch them from the other class and listen to them in your listening class. Here is some code

In class A (assuming it inherits EventDispatcher)

public function classAMethod():void
{
   dispatchEvent(new Event("someCustomTypeForEvent"));
}

In class B (assuming it has a reference to Class A)

public function classBMethod():void
{
   classA.addEventListener("someCustomTypeForEvent",customHandler);
}

public function customHandler(e:Event):void
{
   trace("handle event");
}
