<div class="descr">
<h2>Detailed Description</h2>
<p>The QDeclarativeNdefRecord class implements the <a href="qml-ndefrecord.html">NdefRecord</a> element in QML.</p>
<p>The QDeclarativeNdefRecord class is the base class for all <a href="qml-ndefrecord.html">NdefRecord</a> elements in QML. To support a new NDEF record type in QML subclass this class and expose new properties, member functions and signals appropriate for the new record type. The following must be done to create a new NDEF record type in QML:</p>
<ul>
<li>The subclass must have a <a href="http://qt.nokia.com/doc/4.7/qobject.html#Q_OBJECT">Q_OBJECT</a> macro in its declaration.</li>
<li>The subclass must have an <a href="http://qt.nokia.com/doc/4.7/qobject.html#Q_INVOKABLE">invokable</a> constructor that takes a <a href="qndefrecord.html">QNdefRecord</a> and a <a href="http://qt.nokia.com/doc/4.7/qobject.html">QObject</a> pointer.</li>
<li>The subclass must be declared as an NDEF record by expanding the <a href="qdeclarativendefrecord.html#Q_DECLARE_NDEFRECORD">Q_DECLARE_NDEFRECORD</a>() macro in the implementation file of the subclass.</li>
<li>The subclass must be registered with QML.</li>
</ul>
<p>For example the declaration of such a class may look like the following.</p>
<pre class="cpp"> <span class="keyword">class</span> <span class="type">QDeclarativeNdefFooRecord</span> : <span class="keyword">public</span> <span class="type">QDeclarativeNdefRecord</span>
 {
     Q_OBJECT

     Q_PROPERTY(<span class="type">int</span> foo READ foo WRITE setFoo NOTIFY fooChanged)

 <span class="keyword">public</span>:
     <span class="keyword">explicit</span> <span class="type">QDeclarativeNdefFooRecord</span>(<span class="type"><a href="http://qt.nokia.com/doc/4.7/qobject.html">QObject</a></span> <span class="operator">*</span>parent <span class="operator">=</span> <span class="number">0</span>);
     Q_INVOKABLE <span class="type">QDeclarativeNdefFooRecord</span>(<span class="keyword">const</span> <span class="type"><a href="qndefrecord.html">QNdefRecord</a></span> <span class="operator">&amp;</span>record<span class="operator">,</span> <span class="type"><a href="http://qt.nokia.com/doc/4.7/qobject.html">QObject</a></span> <span class="operator">*</span>parent <span class="operator">=</span> <span class="number">0</span>);
     <span class="operator">~</span><span class="type">QDeclarativeNdefFooRecord</span>();

     <span class="type">int</span> foo() <span class="keyword">const</span>;
     <span class="type">void</span> setFoo(<span class="type">int</span> value);

 <span class="keyword">signals</span>:
     <span class="type">void</span> fooChanged();
 };</pre>
<p>Within the implementation file the <a href="qdeclarativendefrecord.html#Q_DECLARE_NDEFRECORD">Q_DECLARE_NDEFRECORD</a>() macro is expanded:</p>
<pre class="cpp"> <a href="qdeclarativendefrecord.html#Q_DECLARE_NDEFRECORD">Q_DECLARE_NDEFRECORD</a>(<span class="type">QDeclarativeNdefFooRecord</span><span class="operator">,</span> <span class="type"><a href="qndefrecord.html">QNdefRecord</a></span><span class="operator">::</span>ExternalRtd<span class="operator">,</span> <span class="string">&quot;com.example:f&quot;</span>)</pre>
<p>Finially the application or plugin code calls <a href="http://qt.nokia.com/doc/4.7/qdeclarativeengine.html#qmlRegisterType">qmlRegisterType</a>():</p>
<pre class="cpp"> qmlRegisterType<span class="operator">&lt;</span><span class="type">QDeclarativeNdefFooRecord</span><span class="operator">&gt;</span>(uri<span class="operator">,</span> <span class="number">1</span><span class="operator">,</span> <span class="number">0</span><span class="operator">,</span> <span class="string">&quot;NdefFooRecord&quot;</span>);</pre>
