the horizontal scrollbar should be shown when needed but the vertical
scrollbar should always be hidden; "<B>auto +x</B></I>" means the vertical

</pre><H3>DESCRIPTION</H3>
<P>
The <B>tixScrolledWindow</B></I> command creates a new window (given by the
<I>pathName</I></B> argument) and makes it into a ScrolledWindow widget.
Additional options, described above, may be specified on the command
line or in the option database to configure aspects of the
ScrolledWindow widget such as its cursor and relief.
</pre><H3>CREATING WIDGETS INSIDE A SCROLLEDWINDOW WIDGET</H3>
<P>
To create widgets inside a ScrolledWindow widget, one must create the
new widgets relative to the <B>window</B></I> subwidget and manage them
inside the <B>window</B></I> subwidget. An error will be generated if one
tries to create widgets as immediate children of the ScrolledWindow.
For example: the following is correct code, which creates new widgets
inside the window subwidget:
<P>
<pre><code><code><code>
tixScrolledWindow .w; pack .w
set f [.w subwidget window]
button $f.b -text hi -width 40 -height 40
pack $f.b
</code></code></code></pre>
<P>
The following example code is <I>incorrect</I></B> because it tries to
create immediate children of the ScrolledWindow <B>\.w</B></I>:
<P>
<pre><code><code><code>
tixScrolledWindow .w; pack .w
button .w.b -text hi -width 40 -height 40
pack .w.b
</code></code></code></pre>
</pre><H3>WIDGET COMMANDS</H3>
<P>
The <B>tixScrolledWindow</B></I> command creates a new Tcl command whose
command may be used to invoke various
operations on the widget. It has the following general form:
<pre>
<I>pathName option </I></B>?<I>arg arg ...</I></B>?
</pre>
<I>PathName</I></B> is the name of the command, which is the same as
determine the exact behavior of the command. The following
commands are possible for ScrolledWindow widgets:
<DL>
<DT> <I>pathName <B>cget</B></I> <I>option</I></B>
</I></B>
<DD> Returns the current value of the configuration option given by
<I>option</I></B>. <I>Option</I></B> may have any of the values accepted by the
<B>tixScrolledWindow</B></I> command.
</DL>
<DL>
<DT> <I>pathName <B>configure</B></I> ?<I>option</I></B>? <I>?value option value ...</I></B>?
</I></B>
<DD> Query or modify the configuration options of the widget. If
no <I>option</I></B> is specified, returns a list describing all of the
available options for <I>pathName</I></B> (see <B>Tk_ConfigureInfo</B></I> for
information on the format of this list). If <I>option</I></B> is specified
with no <I>value</I></B>, then the command returns a list describing the
one named option (this list will be identical to the corresponding
sublist of the value returned if no <I>option</I></B> is specified). If
one or more <I>option-value</I></B> pairs are specified, then the command
modifies the given widget option(s) to have the given value(s); in
this case the command returns an empty string. <I>Option</I></B> may have
any of the values accepted by the <B>tixScrolledWindow</B></I> command.
</DL>
<DL>
<DT> <I>pathName <B>subwidget <I> name ?args?</I></B>
</I></B>
<DD> When no additional arguments are given, returns the pathname of the
subwidget of the specified name.
When no additional arguments are given, the widget command of the
specified subwidget will be called with these parameters.
