Loading the Display List partially while runtime

Question

Happy Christmas!!
How do I manage that, while the movie starts, some parts of the Display List are "hold in the backhand" and get loaded when I decide that they should.
Can I only do that via external SWF-Files? Further question: Is it possible to stream the files, by calculating the download speed and starting the movie when I want it to do, or is Flash doing that automatically?
Thank you very much.

Answer 1

being a part of the display list me
rely means they will not be redrawn if htey are not on the list and nor will their events be dispatched up through the display list.
this does not mean if they are not onthe list they do not load.
loading a movieClip is something that you must enforce and watch over.
var ldr:Loader= new Loader()    
     ldr.addEventListner(Event.EVENT_COMPLETE,onComplete)
     ldr.load(new URLRequest('external.swf'))
function onComplete(event:Event){
//this fires when your swf has been loaded.  at this point you can add it to the display List
addChild(event.target)
event.target.removeEventListener(Event.EVENT_COMPLETE,onComplete)
this wil add the loaderObject which holds the swf to the stage.
if you have 10 external movies and want to load all 10 before adding any of them to the displayList you can do something like this
var arrayOfMovieClipsToDisplay:Array=new Array()
var counter:int=0
var totalLoads:int=5
var swfsToLoadAr:Array=['external1.swf','external2.swf',external3.swf',external4.swf',externa l5.swf']
for(var i=0;i<totalLoads;i++){
var ldr:Loader= new Loader()    
     ldr.addEventListner(Event.EVENT_COMPLETE,onComplete)
     ldr.load(new URLRequest(swfsToLoadAr[i]))
function onComplete(event:Event){
//this fires when your swf has been loaded.  at this point you can add it to the array
arrayOfMovieClipsToDisplay.push(event.target)
checkLoads()
function checkLoads(){
if(counter<totalLoads){
counter++
}else{
for each(var ldr:Loader in arrayOfMovieClipsToDisplay){
addChild(mc)
