+# 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.
+#
