<!-- $$$QWebInspector-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QWebInspector class allows the placement and control of a <a href="qwebpage.html">QWebPage</a>'s inspector. The inspector can display a page's hierarchy, its loading statistics and the current state of its individual elements. It is mostly used by web developers.</p>
<p>The <a href="qwebpage.html">QWebPage</a> to be inspected must be specified using the <a href="qwebinspector.html#setPage">setPage</a>() method.</p>
<p>A typical use of QWebInspector follows:</p>
<pre class="cpp"> <span class="comment">// ...</span>
<span class="type"><a href="qwebpage.html">QWebPage</a></span> <span class="operator">*</span>page <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qwebpage.html">QWebPage</a></span>;
<span class="comment">// ...</span>
<span class="type">QWebInspector</span> <span class="operator">*</span>inspector <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QWebInspector</span>;
inspector<span class="operator">-</span><span class="operator">></span>setPage(page);</pre>
<p>A QWebInspector can be made visible either programmatically using <a href="qwidget.html#visible-prop">setVisible</a>(), or by the user through the attached <a href="qwebpage.html">QWebPage</a>'s context menu.</p>
<p><b>Note:</b> A QWebInspector will display a blank widget if either:</p>
<ul>
<li><a href="qwebinspector.html#page">page</a>() is null</li>
<li><a href="qwebsettings.html#WebAttribute-enum">QWebSettings::DeveloperExtrasEnabled</a> is false</li>
</ul>
<a name="resources"></a>
<h3>Resources</h3>
<p>This class acts mostly as a container and a controller for the inspector. Most of the resources needed by the inspector are owned by the associated <a href="qwebpage.html">QWebPage</a> and are allocated the first time that:</p>
<ul>
<li>an element is inspected</li>
<li>the QWebInspector is shown.</li>
</ul>
<a name="inspector-configuration-persistence"></a>
<h3>Inspector configuration persistence</h3>
<p>The inspector allows the user to configure some options through its user interface (e.g. the resource tracking "Always enable" option). These settings will be persisted automatically by <a href="qtwebkit.html">QtWebKit</a> only if your application previously called <a href="qcoreapplication.html#organizationName-prop">QCoreApplication::setOrganizationName</a>() and <a href="qcoreapplication.html#applicationName-prop">QCoreApplication::setApplicationName</a>(). See <a href="qsettings.html">QSettings</a>'s default constructor documentation for an explanation of why this is necessary.</p>
