# 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 tixExFileSelectDialog widget --
# This is a neat file selection dialog that will make your apps look
# real good!
#
proc RunSample {w} {
# Create an entry for the user to input a filename. If he can't
# bother to type in the name, he can press the "Browse ..." button
# and call up the file dialog
#

-options {

# [Hint]
# The best way to use an ExFileSelectDialog 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.
