# Paned Widgets
#

# area into two panes with a divider in between that the
# user can adjust. A separate child is placed into each
# pane.
#
# There are a number of options that can be set for each pane.
# This test contains both a horizontal (HPaned) and a vertical
# (VPaned) widget, and allows you to adjust the options for
# each side of each widget.
