Please Help - Fade on load with preloader

Question

Hi All,
I am loading an external swf into an emply mc when a button
is clicked. I have the movie fading in when the button is clicked
by the following code on the button:
on(press){
import mx.transitions.Tween;
var alphaTween:Tween = new Tween(_root.loader_mc, "_alpha",
null , 0, 100, 2, true);
This works great. My problem is, I would like to have a
preloader run until the movie is loaded and THEN have the movie
fade in. Any help on achieving this would be most appreciated.
Thanks,
Eric

This is one of the possible ways to do
import mx.transitions.Tween;
var container:MovieClip = createEmptyMovieClip("loader_mc",
getNextHighestDepth());
var mcLoader:MovieClipLoader = new MovieClipLoader();
mcLoader.addListener(this);
mcLoader.loadClip("1.swf", container);
function onLoadInit(mc:MovieClip) {
var alphaTween:Tween = new Tween(_root.loader_mc, "_alpha",
null , 0, 100, 2, true);
}
