performs the same basic function as a <a class="link" href="class-gtkcheckbutton.html" title="gtk.CheckButton"><code class="classname">gtk.CheckButton</code></a>,
as it's position in the object hierarchy reflects. It is only when multiple
radio buttons are grouped together that they become a different user
interface component in their own right. Every radio button is a member of
some group of radio buttons. When one is selected, all other radio buttons
in the same group are deselected. A <a class="link" href="class-gtkradiobutton.html" title="gtk.RadioButton"><code class="classname">gtk.RadioButton</code></a>
is used to give the user a choice of one of many options.</p><p>Radio button widgets are created with <a class="link" href="class-gtkradiobutton.html#constructor-gtkradiobutton" title="Constructor">gtk.RadioButton</a>() passing
<code class="literal">None</code> as the <em class="parameter"><code>group</code></em> (first) argument
if this is the first radio button in a group. In subsequent calls, pass a
reference to a <a class="link" href="class-gtkradiobutton.html" title="gtk.RadioButton"><code class="classname">gtk.RadioButton</code></a>
as the first argument to specify the group. The second (optional) argument
to <a class="link" href="class-gtkradiobutton.html#constructor-gtkradiobutton" title="Constructor">gtk.RadioButton</a>() is a
label that is used to specify the text of the button. The label text is
parsed for mnemonic characters (preceded by an underscore) to specify an
accelerator for the radiobutton. See <a class="link" href="class-gtkaccelgroup.html" title="gtk.AccelGroup"><code class="classname">gtk.AccelGroup</code></a>
and <a class="link" href="class-gtkaccellabel.html" title="gtk.AccelLabel"><code class="classname">gtk.AccelLabel</code></a>
for more information on mnemonic accelerators.</p><p>To retrieve the group a <a class="link" href="class-gtkradiobutton.html" title="gtk.RadioButton"><code class="classname">gtk.RadioButton</code></a>
is assigned to, use the <a class="link" href="class-gtkradiobutton.html#method-gtkradiobutton--get-group" title="gtk.RadioButton.get_group"><code class="methodname">get_group</code>()</a>
method. To remove a <a class="link" href="class-gtkradiobutton.html" title="gtk.RadioButton"><code class="classname">gtk.RadioButton</code></a>
from one group and make it part of a new one, use the <a class="link" href="class-gtkradiobutton.html#method-gtkradiobutton--set-group" title="gtk.RadioButton.set_group"><code class="methodname">set_group</code>()</a>
