# 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 tixDirList widget -- you can
# use it for the user to select a directory. For example, an installation
# program can use the tixDirList widget to ask the user to select the
# installation directory for an application.
#
proc RunSample {w} {
# Create the tixDirList and the tixLabelEntry widgets on the on the top
# of the dialog box
#

# Create the DirList widget. By default it will show the current
# directory (returned by [pwd])
#
#

# is "transferred" into the entry widget
#
button $w.top.btn -text " >> " -pady 0 \

# We use a LabelEntry to hold the installation directory. The user
# can choose from the DirList widget, or he can type in the directory
# manually
