<!-- $$$Window-description -->
<a name="details"></a>
<h2 id="details">Detailed Description</h2>
<p>The Window object creates a new top-level window for a Qt Quick scene. It automatically sets up the window for use with <code>QtQuick 2.x</code> graphical types.</p>
<p>To use this type, you will need to import the module with the following line:</p>
<pre class="cpp">
import <span class="type">QtQuick</span><span class="operator">.</span>Window <span class="number">2.2</span>
</pre>
<p>Omitting this import will allow you to have a QML environment without access to window system features.</p>
<p>A Window can be declared inside an Item or inside another Window; in that case the inner Window will automatically become "transient for" the outer Window: that is, most platforms will show it centered upon the outer window by default, and there may be other platform-dependent behaviors, depending also on the <a href="qml-qtquick-window-window.html#flags-prop">flags</a>. If the nested window is intended to be a dialog in your application, you should also set <a href="qml-qtquick-window-window.html#flags-prop">flags</a> to Qt.Dialog, because some window managers will not provide the centering behavior without that flag. You can also declare multiple windows inside a top-level QtObject, in which case the windows will have no transient relationship.</p>
<p>Alternatively you can set or bind <a href="qml-qtquick-window-window.html#x-prop">x</a> and <a href="qml-qtquick-window-window.html#y-prop">y</a> to position the Window explicitly on the screen.</p>
<p>When the user attempts to close a window, the <a href="qml-qtquick-window-window.html#closing-signal">closing</a> signal will be emitted. You can force the window to stay open (for example to prompt the user to save changes) by writing an <code>onClosing</code> handler and setting <code>close.accepted = false</code>.</p>
