# 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 how to use multiple columns and multiple styles
# in the tixHList widget
#
# In a tixHList widget, you can have one ore more columns. 
#

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

	hlist.columns 3

    # Create the title for the HList widget
    #	>> Notice that we have set the hlist.header subwidget option to true
    #      so that the header is displayed

    # Notice that we use 3 columns in the hlist widget. This way when the user
    # expands the windows wide, the right side of the header doesn't look
    # chopped off. The following line ensures that the 3 column header is
    # not shown unless the hlist window is wider than its contents.
