How to access class functions during events from currentTarget object in AS3

Question

I have loaded movieClip to stage and was performing some events on that movieClip. Movie clip has own public functions and variables, and those are NOT accessible through currentTarget object in events.

Here is sample class:

package {
    import flash.display.MovieClip;
    import flash.display.Shape;
    public class SampleClass extends MovieClip {
        var str:String;
        public function SampleClass() {
            str="Some string";
            /* draw just a sample rectangle to click on it */
            var rectangle:Shape=new Shape  ;
            rectangle.graphics.beginFill(0x000000);
            rectangle.graphics.drawRect(0,0,100,100);
            rectangle.graphics.endFill();
        }
        public function getStr():String {
            return str;
        }
    }
}

And here is loading on the stage and creating event:

package {
    import flash.display.MovieClip;
    import flash.events.MouseEvent;
    public class MainClass extends MovieClip {
        var a:SampleClass;
        public function MainClass() {
            a=new SampleClass();
            addChild(a);
            a.addEventListener(MouseEvent.CLICK,clickEvent);
        }
        function clickEvent(evt:MouseEvent):void {
            var Obj=evt.currentTarget;
            trace (Obj.getStr());
        }
    }
}

Tracing will return null instead of string value cause currentTarget is an Object, not a Class (movieClip). Any idea how to solve this?

Seems like you need to cast it first: var Obj=SampleClass(evt.currentTarget); — Ivan Chernykh

//use this code it will work

 function clickEvent(evt:MouseEvent):void {
        var Obj:SampleClass = evt.currentTarget as SampleClass;
        trace (Obj.getStr());
 }
