Passing value to different class problem

1

Hi,
I have those 2 function inside a class named MenuScreen.as, What I want to do is send a value true or false to another class named Game.as

If the user clicked mouse icon the value must be true and if user clicked keyboard icon it must be false.

public function onClickStartKeyControl( event:MouseEvent):void
        {
            dispatchEvent( new NavigationEvent( NavigationEvent.START ) );
            
        }
        
        public function onClickStartMouseControl( event:MouseEvent):void
        {
            dispatchEvent( new NavigationEvent( NavigationEvent.START ) );
        }

Can some one help me please…
