# Tix Demostration Program
#
# This sample program is structured in such a way so that it can be
# executed from the Tix demo program "tixwidgets": it must have a
# procedure called "RunSample". It should also have the "if" statment
# at the end of this file so that it can be run as a standalone
# program.

# This file demonstrates the use of the tixComboBox widget, which is close
# to the MS Window Combo Box control.
#

    # $w.top.a is a drop-down combo box. It is not editable -- who wants
    # to invent new months?
    #
    # [Hint] The -options switch sets the options of the subwidgets.
    # [Hint] We set the label.width subwidget option of both comboboxes to 
    #        be 10 so that their labels appear to be aligned.
    #

    # $w.top.b is a non-drop-down combo box. It is not editable: we provide
    # four choices for the user, but he can enter an alternative year if he
    # wants to.
    #
    # [Hint] Use the padY and anchor options of the label subwidget to
    #       align the label with the entry subwidget.
    # [Hint] Notice that you should use padY (the NAME of the option) and not
    #        pady (the SWITCH of the option).
