calling functions from nested movie clips

[maxpower78]

Hi!

I have a function:

function changeCursor(Event:MouseEvent):void
{
 trace("AS3 is imposible to understand");
}

And I have a mc on the stage that have a code inside to attach a scroll from the library. This scroll load a mc called "Rotuladores1", and inside this mc I have my button "r1".

The "r1" button have this code:

r1.addEventListener(MouseEvent.CLICK, r1Handler);

function r1Handler(event:MouseEvent):void{
    Rotuladores1(parent).changeCursor();
    }

This is the code I've used in the mc to attach the scroll to the stage:

stop();
//scroll
import fl.controls.ScrollBar;
import fl.events.ScrollEvent;

var mc:Rotuladores1 = new Rotuladores1();
mc.x = 7;
mc.y = 360;

var mcMask:MovieMaskMC = new MovieMaskMC();
mcMask.x = mc.x;
mcMask.y = mc.y;
mc.mask = mcMask;

var sb:ScrollBar = new ScrollBar();
sb.x = mc.x + mc.width;
sb.y = mc.y;
sb.height = 164;
sb.enabled = true;
sb.setScrollProperties(mcMask.height, 0, (mc.height-mcMask.height));
sb.addEventListener(ScrollEvent.SCROLL, scrollMC);

parent.addChild(mc);
parent.addChild(mcMask);
parent.addChild(sb);

function scrollMC(event:ScrollEvent):void
{
    mc.y = -event.position + mcMask.y;
}

But when I press the button I get this error:

TypeError: Error #1034: Type Coercion failed: cannot convert Main@31f590e1 to Rotuladores1.
at Rotuladores1/r1Handler()

How can I call the function in the main timeline from that button?

Thanks.

Your description is confusing, probably because you are confused.

There is no loading going on here. You are simply instantiating a new Rotuladores1. Apparently the r1Handler is in Rotuladores1, so the parent will not be a Rotuladores1, it will be whatever you added the Rotuladores1 to. In this case, you added it to the stage. You should not do that. Add things to the root instead of the stage.

//Don't do this.  parent is the stage.
//parent.addChild(mc);
//parent.addChild(mcMask);
//parent.addChild(sb);

//Do this:
addChild(mc);
addChild(mcMask);
addChild(sb);

So you do not need to cast the parent to Rotuladores1, which doesn't even have a changeCursor function, you need to cast it to Main or MovieClip.

r1.addEventListener(MouseEvent.CLICK, r1Handler);

function r1Handler(event:MouseEvent):void{
    MovieClip(root).changeCursor();
}

I used root here because your function is on the main timeline. Parent should also have worked, but only if your Rotuladores1 was directly on the root, which it is after fixing the way you added it.
