in web pages.</p>
<p>The HTML <tt><object></tt> tag is used to embed arbitrary
content into a web page, for example:</p>
<pre class="highlightedCode brush: cpp">
<object type="application/x-pdf" data="http://qt.nokia.com/document.pdf" width="500" height="400"></object>
</pre>
<p><a href="demos.html#qtwebkit">QtWebkit</a> will natively handle
the most basic data types like <tt>text/html</tt> and
<tt>image/jpeg</tt>, but for any advanced or custom data types you
will need to provide a handler yourself.</p>
<p>QWebPluginFactory is a factory for creating plugins for <a href="qwebpage.html">QWebPage</a>, where each plugin provides support
for one or more data types. A plugin factory can be installed on a
<a href="qwebpage.html">QWebPage</a> using <a href="qwebpage.html#setPluginFactory">QWebPage.setPluginFactory</a>().</p>
<p><b>Note:</b> The plugin factory is only used if plugins are
enabled through <a href="qwebsettings.html">QWebSettings</a>.</p>
<p>You provide a QWebPluginFactory by implementing the <a href="qwebpluginfactory.html#plugins">plugins</a>() and the <a href="qwebpluginfactory.html#create">create</a>() methods. For <a href="qwebpluginfactory.html#plugins">plugins</a>() it is necessary to
describe the plugins the factory can create, including a
description and the supported MIME types. The MIME types each
plugin can handle should match the ones specified in in the HTML
<tt><object></tt> tag of your content.</p>
<p>The <a href="qwebpluginfactory.html#create">create</a>() method
is called if the requested MIME type is supported. The
implementation has to return a new instance of the plugin requested
for the given MIME type and the specified URL.</p>
<p>The plugins themselves are subclasses of <a href="qobject.html">QObject</a>, but currently only plugins based on
either <a href="qwidget.html">QWidget</a> or <a href="qgraphicswidget.html">QGraphicsWidget</a> are supported.</p>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="Extension-enum" />QWebPluginFactory.Extension</h3><hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QWebPluginFactory" />QWebPluginFactory.__init__ (<i>self</i>, <a href="qobject.html">QObject</a> <i>parent</i> = None)</h3><p>The <i>parent</i> argument, if not None, causes <i>self</i> to be owned by Qt instead of PyQt.</p><p>Constructs a <a href="qwebpluginfactory.html">QWebPluginFactory</a> with parent
<i>parent</i>.</p>
<h3 class="fn"><a name="create" /><a href="qobject.html">QObject</a> QWebPluginFactory.create (<i>self</i>, QString <i>mimeType</i>, <a href="qurl.html">QUrl</a> <i>url</i>, QStringList <i>argumentNames</i>, QStringList <i>argumentValues</i>)</h3><p>This method is abstract and should be reimplemented in any sub-class.</p><p>Implemented in subclasses to create a new plugin that can
display content of the MIME type given by <i>mimeType</i>. The URL
of the content is provided in <i>url</i>. The returned object
should be a <a href="qwidget.html">QWidget</a>.</p>
<p>The HTML object element can provide parameters through the
<tt><param></tt> tag. The name and the value attributes of
these tags are specified by the <i>argumentNames</i> and
<i>argumentValues</i> string lists.</p>
<p>For example:</p>
<pre class="highlightedCode brush: cpp">
<object type="application/x-pdf" data="http://qt.nokia.com/document.pdf" width="500" height="400">
<param name="showTableOfContents" value="true" />
<param name="hideThumbnails" value="false" />
</object>
</pre>
<p>The above object element will result in a call to create() with
the following arguments:</p>
<table class="generic">
<thead>
<tr class="qt-style topAlign">
<th>Parameter</th>
<th>Value</th>
</tr>
</thead>
<tr class="odd topAlign">
<td>
<p>mimeType</p>
</td>
<td>
<p>"application/x-pdf"</p>
</td>
</tr>
<tr class="even topAlign">
<td>
<p>url</p>
</td>
<td>
<p>"http://qt.nokia.com/document.pdf"</p>
</td>
</tr>
<tr class="odd topAlign">
<td>
<p>argumentNames</p>
</td>
<td>
<p>"showTableOfContents" "hideThumbnails"</p>
</td>
</tr>
<tr class="even topAlign">
<td>
<p>argumentVaues</p>
</td>
<td>
<p>"true" "false"</p>
</td>
</tr>
</table>
<p><b>Note:</b> Ownership of the returned object will be
transferred to the caller.</p>
