<h2>Detailed Description</h2>
<p>The QDeclarativeError class encapsulates a QML error.</p>
<p>QDeclarativeError includes a textual description of the error, as well as location information (the file, line, and column). The <a href="qdeclarativeerror.html#toString">toString</a>() method creates a single-line, human-readable string containing all of this information, for example:</p>
<pre class="cpp"> file:<span class="comment">///home/user/test.qml:7:8: Invalid property assignment: double expected</span></pre>
<p>You can use <a href="qtglobal.html#qDebug">qDebug</a>() or <a href="qtglobal.html#qWarning">qWarning</a>() to output errors to the console. This method will attempt to open the file indicated by the error and include additional contextual information.</p>
<pre class="cpp"> file:<span class="comment">///home/user/test.qml:7:8: Invalid property assignment: double expected</span>
         y: <span class="string">&quot;hello&quot;</span>
            <span class="operator">^</span></pre>
