to implement the iphone-like 'floating scrollbar'


i am planning to implement some iphone-like 'floating scrollbar', that
is, the scrollbar only appears when the content is scrolled, and it
will disappear moments later. i tried to catch the expose event of the
eventbox, and draw the scrollbar there, however it does not work,
since the widget in the eventbox always got updated after the expose

could someone give some hint on how to do that?
