<pre>
Name: <B>orient</B>
Class: <B>Orient</B>

<P>
</pre><HR>
</pre><H2>DESCRIPTION</H2>
<P>
The <B>buttonbox</B> command creates a manager widget for controlling
buttons. The button box also supports the display and invocation
of a default button. The button box can be configured either horizontally
or vertically.
</pre><H2>METHODS</H2>
<P>
The <B>buttonbox</B> command creates a new Tcl command whose
name is <I>pathName</I>. This
command may be used to invoke various
operations on the widget. It has the following general form:
<pre>
<I>pathName option </I>?<I>arg arg ...</I>?
</pre>
<I>Option</I> and the <I>arg</I>s
determine the exact behavior of the command.
<P>
Many of the widget commands for the buttonbox take as one argument an
indicator of which button of the button box to operate on. These
indicators are called <I>indexes</I> and allow reference and manipulation
of buttons regardless of their current map state. buttonbox indexes
may be specified in any of the following forms:
<DL>
<DT> <I>number</I>
</I></B>
<DD> Specifies the button numerically, where 0 corresponds to the
left/top-most button of the button box.
</DL>
<DL>
<DT> <B>end</B>
</I></B>
<DD> Indicates the right/bottom-most button of the button box.
</DL>
<DL>
<DT> <B>default</B>
</I></B>
<DD> Indicates the current default button of the button box. This is the
button with the default ring displayed.
</DL>
<DL>
<DT> <I>pattern</I>
</I></B>
<DD> If the index doesn't satisfy one of the above forms then this
form is used. <I>Pattern</I> is pattern-matched against the tag of
each button in the button box, in order from left/top to right/left,
until a matching entry is found. The rules of <B>Tcl_StringMatch</B>
are used.
</DL>
</pre><H2>WIDGET-SPECIFIC METHODS</H2>
<DL>
<DT> <I>pathName <B>add</B> <I>tag</I> <I>args</I>
</I></B>
<DD> Add a button distinguished by <I>tag</I> to the end of the button box.
If additional arguments are present they specify options to be applied
to the button. See <B>PushButton</B> for information on the options
available.
</DL>
<DL>
<DT> <I>pathName <B>buttonconfigure</B> <I>index</I> ?<I>options</I>?
</I></B>
<DD> This command is similar to the <B>configure</B> command, except that
it applies to the options for an individual button,
whereas <B>configure</B> applies to the options for the button box as a whole.
<I>Options</I> may have any of the values accepted by the <B>PushButton</B>
command. If <I>options</I> are specified, options are modified
as indicated in the command and the command returns an empty string.
If no <I>options</I> are specified, returns a list describing
the current options for entry <I>index</I> (see <B>Tk_ConfigureInfo</B> for
information on the format of this list).
</DL>
<DL>
<DT> <I>pathName <B>cget</B> <I>option</I>
</I></B>
<DD> Returns the current value of the configuration option given
by <I>option</I>.
<I>Option</I> may have any of the values accepted by the <B>buttonbox</B>
command.
</DL>
<DL>
<DT> <I>pathName</I> <B>configure</B> ?<I>option</I>? ?<I>value option value ...</I>?
</I></B>
<DD> Query or modify the configuration options of the widget.
If no <I>option</I> is specified, returns a list describing all of
the available options for <I>pathName</I> (see <B>Tk_ConfigureInfo</B> for
information on the format of this list). If <I>option</I> is specified
with no <I>value</I>, 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> is specified). If
one or more <I>option-value</I> 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> may have any of the values accepted by the <B>buttonbox</B>
command.
</DL>
<DL>
<DT> <I>pathName <B>default</B> <I>index</I>
</I></B>
<DD> Sets the default button to the button given by <I>index</I>. This causes
the default ring to appear arround the specified button.
</DL>
<DL>
<DT> <I>pathName <B>delete</B> <I>index</I>
</I></B>
<DD> Deletes the button given by <I>index</I> from the button box.
</DL>
<DL>
<DT> <I>pathName <B>hide</B> <I>index</I>
</I></B>
<DD> Hides the button denoted by <I>index</I>. This doesn't remove the button
permanently, just inhibits its display.
</DL>
<DL>
<DT> <I>pathName <B>index <I>index</I>
</I></B>
<DD> Returns the numerical index corresponding to <I>index</I>.
</DL>
<DL>
<DT> <I>pathName <B>insert <I>index</I> <I>tag</I> ?<I>option value option value ...</I>?
</I></B>
<DD> Same as the <B>add</B> command except that it inserts the new
button just before the one given by <I>index</I>, instead of appending
to the end of the button box. The <I>option</I>, and <I>value</I>
arguments have the same interpretation as for the <B>add</B> widget
command.
</DL>
<DL>
<DT> <I>pathName <B>invoke</B> <I>?index?</I>
</I></B>
<DD> Invoke the command associated with a button. If no arguments
are given then the current default button is invoked, otherwise the argument
is expected to be a button <I>index</I>.
</DL>
<DL>
<DT> <I>pathName <B>show</B> <I>index</I>
</I></B>
<DD> Display a previously hidden button denoted by <I>index</I>.
</DL>
