# A ScrolledList widget feels like a list widget but also has a
# vertical scroll bar on its right. (Later, options may be added to
# add a horizontal bar as well, to make the bars disappear
# automatically when not needed, to move them to the other side of the
# window, etc.)
#
# Configuration options are passed to the List widget.
# A Frame widget is inserted between the master and the list, to hold
# the Scrollbar widget.
# Most methods calls are inherited from the List widget; Pack methods
# are redirected to the Frame widget however.
