<h2>Qt 4.7.1</h2>
<a name="qtquick-namespace"></a>
<h3>QtQuick namespace</h3>
<p>In prior Qt releases, all the Qt Quick elements were available in the <i>Qt</i> namespace. Starting with Qt 4.7.1, the elements are also available in the <i>QtQuick</i> namespace, which improves naming consistency, and allows the development of Qt Quick to occur at a faster rate than Qt's usual minor release schedule.</p>
<p>The change for developers is very simple - where you previously wrote <i>import Qt 4.7</i>, just replace it with <i>import QtQuick 1.0</i>, like this:</p>
<pre class="cpp"> import <span class="type">QtQuick</span> <span class="number">1.0</span>
Text {
text: <span class="string">"Welcome to QtQuick 1.0!"</span>
}</pre>
<p><i>import Qt 4.7</i> continues to work so existing applications won't break even if they aren't updated, but it is recommended that all import statements be modified to the new form.</p>
