# Toolbar
# ----------------------------------------------------------------------
#
# The Toolbar command creates a new window (given by the pathName
# argument) and makes it into a Tool Bar widget. Additional options,
# described above may be specified on the command line or in the
# option database to configure aspects of the Toolbar such as its
# colors, font, and orientation. The Toolbar command returns its
# pathName argument. At the time this command is invoked, there
# must not exist a window named pathName, but pathName's parent
# must exist.
#
# A Toolbar is a widget that displays a collection of widgets arranged
# either in a row or a column (depending on the value of the -orient
# option). This collection of widgets is usually for user convenience
# to give access to a set of commands or settings. Any widget may be
# placed on a Toolbar. However, command or value-oriented widgets (such
# as button, radiobutton, etc.) are usually the most useful kind of
# widgets to appear on a Toolbar.
#
# WISH LIST:
# This section lists possible future enhancements.
#
# Toggle between text and image/bitmap so that the toolbar could
# display either all text or all image/bitmaps.
# Implementation of the -toolbarfile option that allows toolbar
# add commands to be read in from a file.
