You can’t use EventType on MC since they have built-in dispatchEvent… but if the MC is dynamic, you can add variables to MC in run-time, e.g-

kub.data = “Test”
kub.addEventListener(”mouseDown”, down);
function down(e:Event){
trace(e.target.data);
}

Note: MC needs to have customized class that extends MovieClip and has dynamic attribute, you create dynamic classes by using the dynamic attribute when you declare a class, e.g- “dynamic class kub”

kub.dispatchEvent(new EventType(”mouseDown”, true, true, “slav”));

kub.addEventListener(”mouseDown”, down);

function down(e:EventType){

trace(e.arg);
}

Is possible use that way?
p.s. “kub” is a MC.

The function that handle the event will need to be typed to “EventType” or post your code here.

I received that: TypeError: Error #1034: Type Coercion failed: cannot convert flash.events::MouseEvent@30ab601 to EventType.

I understand what means, but i don’t understand why? What am i doing wrong?

Feel free to change whatever u want but doesn’t it mean that u will need to define the object variable every time u want a new parameter to pass on since the rest parameter only returns array? and u won’t be able to pass unlimited parameters?

e.g-
public function EventType(type:String, bubbles:Boolean = false, cancelable:Boolean = false, … a:*) {

super(type, bubbles, cancelable);
arg.size = a[0];
arg.type= a[1];
}

Unless u want to instantiate the EventType class first at client, e.g-

var e:EventType = new EventType(”TYPE_NAME”);
e.arg.size = “size”;
e.arg.type = “type”;
dispatchEvent(e);

But it will make the code much longer…
