The CAPI lets you specify horizontal or vertical scroll bars for any subclass of the
simple-pane
element (including all of the classes described in this chapter).
Horizontal and vertical scroll bars can be specified using the keywords
:horizontal-scroll
and
:vertical-scroll
. By default, both
:vertical-scroll
and
:horizontal-scroll
are
nil
.
