<div class="descr"> <a name="details"></a>
<p>This example builds on:</p>
<ul>
<li><a href="qtqml-referenceexamples-coercion-example.html">Extending QML - Inheritance and Coercion Example</a></li>
<li><a href="qtqml-referenceexamples-properties-example.html">Extending QML - Object and List Property Types Example</a></li>
<li><a href="qtqml-referenceexamples-adding-example.html">Extending QML - Adding Types Example</a></li>
</ul>
<p>The Methods Example has an additional method in the <code>BirthdayParty</code> class: <code>invite()</code>. <code>invite()</code> is declared with <a href="../qtcore/qobject.html#Q_INVOKABLE">Q_INVOKABLE</a> so that it can be called from QML.</p>
<pre class="cpp">
Q_INVOKABLE <span class="type">void</span> invite(<span class="keyword">const</span> <span class="type"><a href="../qtcore/qstring.html">QString</a></span> <span class="operator">&</span>name);
</pre>
<p>In <code>example.qml</code>, the <code>invite()</code> method is called in the <a href="qml-qtqml-component.html#completed-signal">Component.onCompleted</a> signal handler:</p>
<pre class="qml">
import QtQuick 2.0
import People 1.0
<span class="type">BirthdayParty</span> {
<span class="name">host</span>: <span class="name">Person</span> {
<span class="name">name</span>: <span class="string">"Bob Jones"</span>
<span class="name">shoeSize</span>: <span class="number">12</span>
}
<span class="name">guests</span>: [
<span class="type">Person</span> { <span class="name">name</span>: <span class="string">"Leo Hodges"</span> },
<span class="type">Person</span> { <span class="name">name</span>: <span class="string">"Jack Smith"</span> },
<span class="type">Person</span> { <span class="name">name</span>: <span class="string">"Anne Brown"</span> }
]
<span class="name">Component</span>.onCompleted: <span class="name">invite</span>(<span class="string">"William Green"</span>)
}
