You get the message because getChildAt returns a DisplayObject which does
not have a getChildAt method (that's what the error message is saying). You
have first to cast the object returned from the first getChildAt call to a
DisplayObjectContainer or a subclass of it (in your case it's a VBox). There
are different ways to do it, one way would be:
var theVidButton:VBox = (vidButtonBox.getChildAt(0) as VBox).getChildAt(0)
as VBox;
You must make sure that vidButtonBox.getChildAt(0) will return a VBox
otherwise you will get an exception! It's better to do something like this:
var theVidButton:VBox = null;
var vidButtonContainer:VBox = vidButtonBox.getChildAt(0) as VBox;
if (vidButtonContainer != null)
{
theVidButton = vidButtonContainer.getChildAt(0) as VBox;
}
if (theVidButton == null)
{
//something went wrong
}
Hope it helps!
