How do I make a swf the parent of others?

[worcesters]

Hi There,

I currently have three swf files: master.swf, navigation.swf and portfolio.swf. master.swf is essentially a background, navigation.swf is made up of four animated movieclips that I am using as buttons and portfolio.swf contains a simple coloured block.

I have loaded navigation.swf into my master file successfully, but I am having trouble loading my portfolio.swf into the master via the navigation.swf.

I am trying to use the image loader in my master file so that i can specify a level for the swf to display on beneath my navigation.swf, which I want to always remain on screen at the top of the stacking order.

To use the imageloader of the master file while writing code in the navigation file do I have to link them in a parent/child relationship somehow? If so how do you do this?

Here is the code in my master.fla:

var nav_btnsRequest:URLRequest = new URLRequest("navigation_btns.swf");

var nav_btnsLoader:Loader = new Loader();
nav_btnsLoader.load(nav_btnsRequest);

addChildAt(nav_btnsLoader, 1);

and here is the code that I have tried to use in my navigation.fla to load the portfolio into the master file once the relevant button is clicked:

stop();

pin_01.addEventListener(MouseEvent.CLICK, onClick_01);

function onClick_01(event:MouseEvent):void
{
	pin_01.play();
	var portfolioReq:URLRequest = new URLRequest("portfolio.swf");
	Loader(root.parent).load(portfolioReq, 1);
}

Any ideas what i should try? Thanks all

ok i think i may have solved this myself but it has spawned a new question. I have added a new image loader on my navigation.swf and loaded the portfolio swf into that. this then works fine in my master.swf.

However, how can I change the stacking order of the swfs so that the navigation swf is on level 1 and the new loaded portfolio swf is on level 0?

Here's the rewritten bit of code:
stop();

var imageLoader:Loader = new Loader();

pin_01.addEventListener(MouseEvent.CLICK, onClick_01);

function onClick_01(event:MouseEvent):void
{
pin_01.play();
var portfolioReq:URLRequest = new URLRequest("portfolio.swf");
imageLoader.load(portfolioReq);
addChildAt(imageLoader, 1);
}
