# 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.
|

|
|
# 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
