firstIndexInView

In a previous example, “Determining the first and last visible item in a scrolling VGroup container in Flex 4″, we saw how you could determine the first and last item in a Spark VGroup container’s view by using the firstIndexInView and lastIndexInView properties on the VGroup container’s layout property.

The following example shows how you can determine how much of an item is visible in a scrolling VGroup container in Flex 4 by using the fractionOfElementInView() method.
