<div class="descr"> <a name="details"></a>
<p>The <a href="qtqml-index.html">Qt QML</a> module provides the definition and implementation of various convenience types which can be used with the QML language, including some elementary QML types which can provide the basis for further extensions to the QML language. The <a href="qml-qtqml-qtobject.html">QtObject</a> and <a href="qml-qtqml-component.html">Component</a> object types are non-visual and provide building-blocks for extensions to QML.</p>
<a name="importing-qtqml"></a>
<h2 id="importing-qtqml">Importing QtQml</h2>
<p>The types provided by the <code>QtQml</code> module are only available in a QML document if that document imports the <code>QtQml</code> namespace (or if the document imports the <code>QtQuick</code> namespace, as noted below).</p>
<p>The current version of the <code>QtQml</code> module is version 2.12, and thus it may be imported via the following statement:</p>
<pre class="qml">
</pre>
<p>Most clients will never need to use the <code>QtQml</code> import, as all of the types are also provided by the <code>QtQuick</code> namespace which may be imported as follows:</p>
<pre class="qml">
</pre>
<p>See the Qt Quick module documentation for more information about the <code>QtQuick</code> namespace and what it provides to QML application developers.</p>
<p>The QML types for creating lists and models, such as <a href="qml-qtqml-models-listmodel.html">ListModel</a> and <a href="qml-qtqml-models-listelement.html">ListElement</a>, are moved to a submodule, <code>QtQml.Models</code>. The <a href="qtqml-models-qmlmodule.html">Qt QML Models</a> page has more information.</p>
<p>The documentation for the types below applies equally to the types of the same name provided by the Qt Quick module, as they are in fact identical.</p>
