    <title>Användbara metoder för en LinkButton-komponent</title>
    <list>
      <item><p><code>get_visited()</code> returns the 'visited' state (<code>True</code> or <code>False</code>) of the URI where the LinkButton points. The button becomes visited when it is clicked.</p></item>
      <item><p><code>set_visited(True)</code> sets the 'visited' state of the URI where the LinkButton points as <code>True</code> (analogously for <code>False</code>).</p></item>
      <item><p>Each time the button is clicked, the signal <code>"activate-link"</code> is emitted. For an explanation of signals and callback functions, see <link xref="signals-callbacks.py"/>.</p></item>
