Hi,
I recently did something like this. But it was more complicated because
I was loading a swf from a different domain from it's parent. I needed
to attach an event handler to the swf when SWFLoader was done loading.
Then at some point, the loaded swf would broadcast an event, and the
parent swf would be able to respond.
Contrary to what the last poster said, I think you should consider
listening for the Event.INIT, not Event.Complete broadcast by your
SWFLoader. To determine which one you need, check descriptions of these
two events in the Flex 3 Language Reference. Here's the meat of it:
INIT is broadcast when the properties and methods of a loaded SWF file
are accessible.
COMPLETE is broadcast when content loading is complete.
So, if you need to be able to access child movie clips, I'd say use
INIT.
Here's some code. Please note that both parent and child are Flex
applications, yielding parent.swf and child.swf.
In parent.swf:
mySwfLoader:SWFLoader = new SWFLoader();
mySwfLoader.addEventListener(Event.INIT, onInit);
function onInit(event:Event):void
{
mySwfLoader.content.addEventListener("myEventName",
onMyEventHandler);
}
function onMyEventHandler(event:Event):void
{
//do something
}
In child.swf:
//broadcast events that parent.swf can respond to.
systemManager.dispatch(new Event("myChild"));
I found that when loading a Flex generated child.swf,
mySwfLoader.content is a reference to the child.swf's systemManager
property. So in order to broadcast events from my loaded swf, you
needed to dispatch the event using the child application's systemManager
property. Hence the last line of code.
Hope that helps.

SWFLoader loads from the network are asynchronous. You'll always have
to wait to access the data
