<h2><a name="SECTid8206798">DESCRIPTION</a></h2><p>
<b>radiobutton</b> widgets are used in groups to show or change
a set of mutually-exclusive options.
Radiobuttons are linked to a Tcl variable,
and have an associated value; when a radiobutton is clicked,
it sets the variable to its associated value.

<h2><a name="SECTid8206d88">WIDGET COMMAND</a></h2><p>In addition to the standard
<b>cget</b>, <b>configure</b>, <b>instate</b>, and <b>state</b>
commands, radiobuttons support the following additional
widget commands:
</p><dl>
<dt>
<i class="m">pathname</i> invoke</dt>
<dd>Sets the <i>-variable</i> to the <i>-value</i>, selects the widget,
and evaluates the associated <i>-command</i>.
Returns the result of the <i>-command</i>, or the empty
string if no <i>-command</i> is specified.
</dd>
</dl>
<h2><a name="SECTid8207030">WIDGET STATES</a></h2><p>The widget does not respond to user input if the <b>disabled</b> state is set.
The widget sets the <b>selected</b> state whenever
the linked <b>-variable</b> is set to the widget's <b>-value</b>,
and clears it otherwise.
The widget sets the <b>alternate</b> state whenever the
linked <b>-variable</b> is unset.
(The <b>alternate</b> state may be used to indicate a ``tri-state''
or ``indeterminate'' selection.)
