Add Sprite into Container . Use ClassFactory for itemRenderer.

Sprite : - It's needed when any flash component is add into container.
UIComponent :- It is used for adding Flash component.

If we want to add flash component into canvas then
1. Create flash component object.
2. Create Sprite object and add flash component object.
3. Create UIComponent object and add Sprite object.
4. Get Canvas container object "objCan" then add UIComponent object.
objCan.rawChildren.addChild(objUIComponent);

Here we need rawChildern property for adding objUIComponent.

ClassFactory : - When any dynamic Grid, TileList , List component need ItemRender which is also dynamic then we need to create ClassFactory Object for applying dynamic ItemRender.


var itemRenderer:ClassFactory = new ClassFactory(itemReaderClassType)
tl.itemRenderer = itemRenderer;

On Item Render need override method :
override public function set data(value:Object):void
{
if (value!=null)
{
super.data = value;

}
}
