# 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 tixScrolledHList widget.
#

proc RunSample {w} {

    # We create the frame and the ScrolledHList widget
    # at the top of the dialog box
    #
    frame $w.top -relief raised -bd 1

    # Put a simple hierachy into the HList (two levels). Use colors and
    # separator widgets (frames) to make the list look fancy
    #
    tixScrolledHList $w.top.a
    pack $w.top.a -expand yes -fill both -padx 10 -pady 10 -side left

	#	 the structure of your database, e.g.) you can use the
	#	 "addchild" widget command instead:
	#
	#  $hlist addchild [lindex $line 1] -text [lindex $line 2]
	#                  ^^^^^^^^^^^^^^^^
	#                  parent entryPath
