<P>
A TixHList widget can be created by the command <tt>tixHList</tt>. However, most likely, you would want to create a TixHList
with scrollbars attached. Therefore, usually you will use the <tt>tixScrolledHList</tt> command to create a scrolled hierarchical listbox
(line 1 in program 4-2). The <tt>tixScrolledHList</tt>
command is very similar to the <tt>TixScrolledListBox</tt> command we
saw in section 2.3.1. It creates a TixHList subwidget
of the name <tt>hlist</tt> and attaches two scrollbars to it.
<P>
As shown in the first five lines in program 4-2, we
create a scrolled TixHList widget, using the <tt>-options</tt> switch
(see section 1.3.5) to set several options for the <tt>hlist</tt> subwidget (we'll talk about these options shortly). Then, we
can access the HList subwidget widget using the <tt>subwidget
hlist</tt> method (line 7 in program 4-2).
<P>
<blockquote> <P><tt> tixScrolledHList .sh -options {<BR>
hlist.itemType text<BR>
hlist.drawBranch false<BR>
hlist.indent 8<BR>
}<BR>
pack .sh -expand yes -fill both<BR>
set hlist [.sh subwidget hlist]<BR>
<BR>
$hlist add foo -text &quot;foo&quot;<BR>
$hlist add foo.bar -text &quot;foo's 1st son&quot;<BR>
$hlist add foo.bor -text &quot;foo's 2nd son&quot;<BR>
$hlist add foo.bar.bao -text &quot;foo's 1st son's 1st son&quot;<BR>
$hlist add foo.bar.kao -text &quot;foo's 1st son's 2nd son&quot;<BR>
$hlist add dor -text &quot;dor, who has no son&quot;
</tt>
