# 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 tixDirTree and the tixLabelEntry widgets on the on the top
# of the dialog box
#
frame $w.top -border 1 -relief raised
# Create the DirTree widget. By default it will show the current
# directory (returned by [pwd])
#
#
tixDirTree $w.top.dir -browsecmd "dtree:browse $w.top.ent"
# When the user presses the ".." button, the selected directory
# is "transferred" into the entry widget
#
# We use a LabelEntry to hold the installation directory. The user
# can choose from the DirTree widget, or he can type in the directory
# manually
