# Public: Represents a view that scrolls.
#
# This `View` subclass listens to events such as `page-up`, `page-down`,
# `move-to-top`, and `move-to-bottom`.
#
# FIXME: I don't actually understand if this is useful or not. I think it is
# a base of package widgets but I don't really understand how the core events
# work.
