Sets the adjustment (if any) that the widget uses to
for vertical scrolling.
For instance, this is used to get the page size for
PageUp/Down key handling.
In the normal case when the box is packed inside
a gtk.scrolled_window.ScrolledWindow the adjustment from that will
be picked up automatically, so there is no need
to manually do that.
