[CS3 AS2] loading dynamically positioned movieclips

programming flash
1

We have a main.fla - much of the content positioning part does nothing yet :

import mx.transitions.Tween;
import mx.transitions.easing.*;
stop();

// loader
var myMCL:MovieClipLoader = new MovieClipLoader();
/// tween all loads
var myListener:Object = new Object();
myMCL.addListener(myListener);
myListener.onLoadInit = function(target:MovieClip):Void  {
    tweenImage(target);
};
function tweenImage(target:MovieClip):Void {
    var myTween:Tween = new Tween(target, "_alpha", mx.transitions.easing.Regular.easeIn, 0, 100, 0.5, true);
    //execute when tween complete
    myTween.onMotionFinished = function():Void  {
    };
}
// unless we specifically don't want tweens
var noTweenMCL:MovieClipLoader = new MovieClipLoader();

/* dynamically position content - based on a tutorial from Justin Windle (http://blog.soulwire.co.uk/tag/flash) */
// Setup the Stage properties
Stage.scaleMode = "noScale";
Stage.align = "TL";

// Variables (in pixels) 
var navHeight:Number = 435;
var navWidth:Number = 222;
var contactHeight:Number = 0;
var contactWidth:Number = 0;
var descHeight:Number = 117;
var descWidth:Number = 222;

// Variables (in percent)
var headHeight:Number = 11;
var galHeight:Number = 60;
var thumbsHeight:Number = 6;

// Prototype function to position MovieClips
MovieClip.prototype.pos = function (r, s, w, h)
{
    this._x = r;
    this._y = s;
    this._width = w;
    this._height = h;
};


// positioning function
function setStage ()
{
    var sw:Number = Stage.width;
    var sh:Number = Stage.height;

    // Calculate dynamic dimensions
    var Ny:Number = sh / 100 * headHeight;
    var Dy:Number = Ny + navHeight;
    var Gw:Number = sw - navWidth - contactWidth;
    var Gh:Number = sh / 100 * galHeight;
    var Cx:Number = navWidth + Gw;
    var Ty:Number = 0.8 * sh;
    var Th:Number = sh / 100 * thumbsHeight;
    var Hh:Number = sh / 100 * headHeight;

//apply sizes & positions
    nav_mc.pos (0, Hh, navWidth, navHeight);
    gal_mc.pos (navWidth, Hh, Gw, Gh);
    contact_mc.pos (Cx, Hh, contactWidth, contactHeight);
    desc_mc.pos (0, Dy, descWidth, descHeight);
    thumbs_mc.pos (navWidth, Ty, Gw, Th);
}


// text "frames" do not resize and image "frames" should fill up all remaining browser space
var stageListener:Object = new Object ();
Stage.addListener (stageListener);
stageListener.onResize = setStage;
setStage ();



//load navigation menu and make clips for the other sections to come
_root.createEmptyMovieClip("nav_mc",1);
myMCL.loadClip("nav.swf","nav_mc");
_root.createEmptyMovieClip("thumbs_mc",2);
_root.createEmptyMovieClip("gal_mc",3);
_root.createEmptyMovieClip("contact_mc",4);
_root.createEmptyMovieClip("desc_mc",5);

ok, then we have nav.fla that only contains one (for now) menu button (named button1_btn) on the stage, and the following code on the timeline:

this.button1_btn.onPress = function() {
    _level0.myMCL.loadClip("button1thumbs.swf","thumbs_mc");
    _level0.setStage();
};

button1thumbs.fla doesn’t have any actions in it (yet) as i cannot get it to load in the space defined by “thumbs_mc”.

For the life of me I just can’t figure out a syntax to make button1thumbs.swf load into that movie clip, and I’ve tried all I can think of, but it’s probably something dumb on my part. Any suggestions?
