ScrollView do something after scroll (delegate / event)

So I got the ScrollView finally to work…
now I am wondering how do I run a function after it has finished scrolling?

Edit: I wrote my own scroll class because scrollview didn’t work as I had hoped… Scrollview is more like scrolling a web page wheras I needed it too scroll in the manner of row-by-row… or in my case, layer-by-layer.
