Sending vars between swfs - External Interface?

[aneemal]

Hi, as always I appreciate suggestions.

On my html page I have two frames, one for navigation and the other for content. The navigation menu is an swf. Most of the content is html, except for the 'gallery' page.

The thumbnails for the gallery appear within the navigation. I can get the pictures to load from the thumbnails into the 'content' frame using LoadVars sendAndLoad.

However, doing this means that the flash gallery refreshes itself each time a thumbnail is clicked (thereby losing the transition effect).

So, how do I load the images in the other frame without reloading the flash??

Could I do it using external interface? ...it seems confusing.

No. Use Local Connection.
external interface is for calling javascript.

That's great! - Exactly what I need!
...and I never heard of it before!
Thank you! ...so simple.

One thing though, somehow my transition still doesn't happen.

Here is the code:

Sending swf:

mc.onMouseDown = function() {
   if (this.hitTest(_xmouse,_ymouse,true)) {
    val = this._parent._name.substr(7,2);
    var sending_lc:LocalConnection = new LocalConnection();
    sending_lc.send("lc_vars","getVars",_global.cID,val);
   }
}

Receiving swf:

var lc_receiver:LocalConnection = new LocalConnection();
lc_receiver.getVars = function(param1:Number,param2:Number) {
    loc = param1;
    num = param2;
    //_root.querystring.text = "var 1 = "+param1+" and var 2 = "+param2;
    if (num != undefined) {
        tmp1 = loader.createEmptyMovieClip("tmp1",1);
        tmp2 = loader.createEmptyMovieClip("tmp2",2);
        levs = 2;
        imgLoader.loadClip(path+loc+"/"+num+".jpg",_root["loader"]["tmp2"]);
    } else {
        _root.querystring.text = "Error loading file";
    }
};

lc_receiver.connect("lc_vars");

imgLoaderListener.onLoadInit = function(mc:MovieClip) {
    centX = Stage.width/2;
    mc._x = centX - (mc._width/2);
    //mc._x = (diffX - mc._width/2);
    frame = _root.attachMovie("frame","frame",-10,{_x:0,_y:0});
    frame._width = mc._width + 30;
    frame._height = mc._height + 40;
    frame._x = mc._x - 15;
    frame._y = mc._y;
    id2 = _root["loader"].getInstanceAtDepth(levs);
    photo_msk = _root.attachMovie("photo_msk","photo_msk",100);
    photo_msk._width = mc._width;
    photo_msk._height = mc._height;
    photo_msk._x = mc._x;
    photo_msk._y = mc._y;
    _root["loader"].setMask(photo_msk);
    if (id2 != mc) {
        mc._alpha = 0;
        mc.swapDepths(id2);
        id2.swapDepths(levs-1);
        fadeIn(mc);
    }
    img_desc._x = mc._x;
    img_desc._y = mc._y + mc._height;
    desc.load(path+loc+"/descriptions.txt");
};

I don't think the onLoadInit function is happening at all? The pictures are loading fine, but no transition.

(This isn't all the code, just the bits affected. The code and transitions work when the variables are sent via php and flashvars...)

Any suggestions?
