# Tix Demostration Program
#
# This sample program is structured in such a way so that it can be
# executed from the Tix demo program "widget": 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 using tixwish.
# This file demonstrates the use of the tixComboBox widget, which is close
# to the MS Window Combo Box control.
#

# Create the comboboxes on the top of the dialog box
#
frame $w.top -border 1 -relief raised
# $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
# aligh 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).
