# 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 tixFileSelectDialog widget --
|
||
|
|
# This is a neat file selection dialog that looks like the Motif
|
||
|
|
# file-selection dialog widget. I know that Motif sucks, but
|
||
|
|
# tixFileSelectDialog looks neat nevertheless.

|

|
|
# The best way to use an FileSelectDialog is not to create one yourself
|

# but to call the command "tix filedialog". This command creates one file
|
||
|
|
# dialog box that is shared by different parts of the application.
|
||
|
|
# This way, your application can save resources because it doesn't
|
||
|
|
# need to create a lot of file dialog boxes even if it needs to input
|
||
|
|
# file names at a lot of different occasions.
