You need to use the enum; Flickable.HorizontalFlick. Unfortunately the fact that you need to prefix enums with element names are not well documented in each of the Enum enumerations.

I have created http://bugreports.qt.nokia.com/browse/QTBUG-10386 that describes the lack of fully qualified enums, please vote / subscribe to this task.
