Handling Scroll Positioning in Spark

This example shows how you would set the scroll position of a scrollable 
component to the max scroll position in Flex 3 and how it is handled in Flex 4.

// Flex 4
// myView = Some view class.
// myScroller = s:Scroller
// myContentContainer = s:Group

var maxScrollPosition:Number = myView.myContentContainer.height - myView.myScroller.viewport.height;
myView.myScroller.viewport.verticalScrollPosition = maxScrollPosition;



// Flex 3		
// myView = Some view class.
// myContentContainer = mx:Canvas

myView.myContentContainer.verticalScrollPosition = myView.myContentContainer.maxVerticalScrollPosition;
