# 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
#

# Put a simple hierachy into the HList (two levels). Use colors and
# separator widgets (frames) to make the list look fancy

# 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.
