<!-- $$$FontLoader-brief -->
<p>The FontLoader element allows fonts to be loaded by name or URL. <a href="#details">More...</a></p>
<!-- @@@FontLoader -->
<p>This element was introduced in Qt 4.7.</p>
<ul>
<li><a href="qml-fontloader-members.html">List of all members, including inherited members</a></li>

<h2>Detailed Description</h2>
<p>The FontLoader element is used to load fonts by name or URL.</p>
<p>The <a href="qml-fontloader.html#status-prop">status</a> indicates when the font has been loaded, which is useful for fonts loaded from remote sources.</p>
<p>For example:</p>
<pre class="qml"> import QtQuick 1.0
<span class="type"><a href="qml-column.html">Column</a></span> {
<span class="type">FontLoader</span> { <span class="name">id</span>: <span class="name">fixedFont</span>; <span class="name">name</span>: <span class="string">"Courier"</span> }
<span class="type">FontLoader</span> { <span class="name">id</span>: <span class="name">webFont</span>; <span class="name">source</span>: <span class="string">"http://www.mysite.com/myfont.ttf"</span> }
<span class="type"><a href="qml-text.html">Text</a></span> { <span class="name">text</span>: <span class="string">"Fixed-size font"</span>; <span class="name">font</span>.family: <span class="name">fixedFont</span>.<span class="name">name</span> }
<span class="type"><a href="qml-text.html">Text</a></span> { <span class="name">text</span>: <span class="string">"Fancy font"</span>; <span class="name">font</span>.family: <span class="name">webFont</span>.<span class="name">name</span> }
