             Summary: Dispatch Scroll Events either from Scroller or (better) from viewport
                 Key: FLEX-33916
                 URL: https://issues.apache.org/jira/browse/FLEX-33916
             Project: Apache Flex
          Issue Type: Improvement
          Components: Spark: Scroller
            Reporter: Giles Roadnight


I am trying to implement some custom scrolling behaviour (specifically a pull to refresh implementation similar to http://www.riagora.com/2011/05/pull-down-to-refresh/ ) and I am very surprised to find out that the only way I can get information on the scroll position of the view port is to add a property change event listener to the dataGroup of the list, check the property for the magic string of "verticalScrollPosition" and then get the actual position. Dispatching a ScrollEvent of some sort will allow me to write much neater and resilient code.
