# 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.
|
||
|
|
|
||
|
|
# Demonstrates how to use compound images to display icons in a canvas widget.
