<p><a href="qml-qtquick-controls2-applicationwindow.html">ApplicationWindow</a> is a <a href="../qtquick/qml-qtquick-window-window.html">Window</a> which makes it convenient to add a <a href="qml-qtquick-controls2-applicationwindow.html#header-attached-prop">header</a> and <a href="qml-qtquick-controls2-applicationwindow.html#footer-attached-prop">footer</a> item to the window.</p>
<p>You can declare <a href="qml-qtquick-controls2-applicationwindow.html">ApplicationWindow</a> as the root item of your application, and run it by using <a href="../qtqml/qqmlapplicationengine.html">QQmlApplicationEngine</a>. In this way you can control the window's properties, appearance and layout from QML.</p>

<p><a href="qml-qtquick-controls2-applicationwindow.html">ApplicationWindow</a> supports popups via its <a href="qml-qtquick-controls2-applicationwindow.html#overlay-attached-prop">overlay</a> property, which ensures that popups are displayed above other content and that the background is dimmed when a <a href="qml-qtquick-controls2-popup.html#modal-prop">modal</a> or <a href="qml-qtquick-controls2-popup.html#dim-prop">dimmed</a> popup is visible.</p>

<h3 >Attached ApplicationWindow Properties</h3>
<p>Due to how <a href="../qtqml/qtqml-documents-topic.html#scope-and-naming-resolution">Scope and Naming Resolution</a> works in QML, it is possible to reference the <code>id</code> of the application root element anywhere in its child QML objects. Even though this approach is fine for many applications and use cases, for a generic QML component it may not be acceptable as it creates a dependency to the surrounding environment.</p>
<p><a href="qml-qtquick-controls2-applicationwindow.html">ApplicationWindow</a> provides a set of attached properties that can be used to access the window and its building blocks from places where no direct access to the window is available, without creating a dependency to a certain window <code>id</code>. A QML component that uses the <a href="qml-qtquick-controls2-applicationwindow.html">ApplicationWindow</a> attached properties works in any window regardless of its <code>id</code>. The following example uses the attached <code>overlay</code> property to position the popup to the center of the window, despite the position of the button that opens the popup.</p>
<pre class="cpp">
Button {
onClicked: popup<span class="operator">.</span>open()
Popup {
id: popup
parent: ApplicationWindow<span class="operator">.</span>overlay
x: (parent<span class="operator">.</span>width <span class="operator">-</span> width) <span class="operator">/</span> <span class="number">2</span>
y: (parent<span class="operator">.</span>height <span class="operator">-</span> height) <span class="operator">/</span> <span class="number">2</span>
