Event dispatcher - actionscript-3

Question

I have two classes and i tried event dispatch from one class to other class. Here i have used button to invoke the class. But dispatch not working.
class name cusDispatcher.as
package
{
import flash.display.MovieClip;
import flash.events.EventDispatcher;
import flash.events.Event;
import flash.events.MouseEvent;
import Globe;
public class CusDispatcher extends EventDispatcher
{
public function CusDispatcher():void
{
Globe.self.realstage.btn_mc.addEventListener(MouseEvent.CLICK,
doAction);
}
public function doAction(event:MouseEvent):void
{
dispatchEvent(new Event('myevent'));
}
}
}
class name EventDispatcherExample.as
package
{
import flash.display.DisplayObject;
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.EventDispatcher;
import Globe;
public class EventDispatcherExample extends EventDispatcher
{
public function EventDispatcherExample(Mc:MovieClip)
{
Globe.self.realstage = Mc;
var start:CusDispatcher = new CusDispatcher();
Globe.self.realstage.addEventListener('myevent', handler);
trace("one");
}
public function handler(event:Event):void
{
trace("My Event");
}
}
}
In the adobe CC i used this instance to run the class
var Call:EventDispatcherExample = new EventDispatcherExample(this);
Whenever i click the button(btn_mc) in the adobe flash cc it does not show any
trace of dispatch event.So could please analyze and give solution for this one.

Answer 1

Is your other click listener (in the EventDispatcherExample) working?
The problem might be that you have declared your CusDispatcher as a local variable within a function
var start:CusDispatcher = new CusDispatcher();
Once the function is complete these variables are cleaned up. Try to declare it at the beginning of your class as a class variable:
private var start:CusDispatcher;
public function EventDispatcherExample(Mc:MovieClip)...
and then assign your new Dispatcher to it
start = new CusDispatcher();
