    <title>RadioButton 위젯에 쓸만한 메서드</title>
    <p>16번째 줄에서 <code>"toggled"</code> 시그널은 <code><var>widget</var>.connect(<var>signal</var>, <var>callback function</var>)</code> 함수로  <code>toggled_cb()</code> 콜백 함수에 연결했습니다. 더 자세한 설명은 <link xref="signals-callbacks.py"/>를 참조하십시오.</p>

    <p><link xref="properties.py"/>에서 보신 바와 같이 <code>, button1 = Gtk.RadioButton(label="Button 1")</code> 대신 다음 코드로 단추와 레이블을 만들 수 있습니다</p>
    <code>
button1 = Gtk.RadioButton()
button1.set_label("Button 1").</code>
    <p>레이블을 붙여서 새 RadioButton을 만드는 또 다른 방법은 <code>button1 = Gtk.RadioButton.new_with_label(None, "Button 1")</code>(처음 인자는 <code>get_group()</code>으로 가져올 수 있는 라디오 단추의 그룹, 두번째 인자는 레이블입니다) 코드를 활용하는 방법입니다.</p>
