flex actionscript dynamically state change and move items

I'm trying to make this : http://livedocs.adobe.com/flex/3/html/help.html?content=transitions_7.html just press back on the bottom of this page to see the filter effect that I want

but dynamically and I did, with the states and everything for n elements. Now my question is how can I make a scroll bar on the left side but when scrolling does not need to affect the big panel so I just want to scroll for example 200 panels and not moving the big panel. part of my code where I put states for every panel: panels is a ArrayList of panels

for(var i:int=0; i<6 ;i++)  
// get panel from list pane开发者_Go百科ls and set states
{
//addChild((panels.getItemAt(i) as Panel)); 
(states[i] as State).overrides=[ new SetProperty(panels.getItemAt(i),"x",110), new SetProperty(panels.getItemAt(i),"y",0), new SetProperty(panels.getItemAt(i),"width",widthBigPanel), new SetProperty(panels.getItemAt(i),"height",heightBigPanel)];
  var yy:int=0;
  for(var k:int=0;k<6;k++)
   {
    if(k!=i){    
(states[i] as State).overrides = (states[i] as State).overrides.concat([ new SetProperty(panels.getItemAt(k),"x",x), new SetProperty(panels.getItemAt(k),"y",yy),
new SetProperty(panels.getItemAt(k),"width",widthPanel), new SetProperty(panels.getItemAt(k),"height",heightPanel)]);
       yy+=110;

      }
     }
