# Tix Demostration Program
#
# This sample program is structured in such a way so that it can be
# executed from the Tix demo program "tixwidgets.py": 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 tixPopupMenu widget.
#

    # button over $w.top or $w.top.but, the PopupMenu will come up.
