|
|
# 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 tixOptionMenu widget -- you can
|
||
|
|
# use it for the user to choose from a fixed set of options
