The actual hScroll of the field isn’t set, only the vScroll is set in this example, but it can detect that you are attempting to scroll horizontally and so you can use that info to initiate a swipe.

It is only a workaround implemented by intercepting the scrollerDidScroll message, you don’t need to ‘set' the scroll sent by the message, but you can detect it and use it to swipe.
