<p>QWebPluginFactory is a factory for creating plugins for <a href="qwebpage.html">QWebPage</a>. 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 can provide a QWebPluginFactory by implementing the <a href="qwebpluginfactory.html#plugins">plugins</a>() and the <a href="qwebpluginfactory.html#create">create</a>() method. 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.</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>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="Extension-enum" />QWebPluginFactory.Extension</h3><p>This enum describes the types of extensions that the plugin factory can support. Before using these extensions, you should verify that the extension is supported by calling <a href="qwebpluginfactory.html#supportsExtension">supportsExtension</a>().</p>
<p>Currently there are no extensions.</p>
<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>
<a name="//apple_ref/cpp/instm/QWebPluginFactory/~QWebPluginFactory" />
<h3 class="fn"><a name="create" /><a href="qobject.html">QObject</a> QWebPluginFactory.create (<i>self</i>, QString, <a href="qurl.html">QUrl</a>, QStringList, QStringList)</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> <object type="application/x-pdf" data="http:<span class="comment">//qt.nokia.com/document.pdf" width="500" height="400"></span>
<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>
<p><table align="center" border="0" cellpadding="2" cellspacing="1" class="generic">
<thead><tr class="qt-style" valign="top"><th>Parameter</th><th>Value</th></tr></thead>
<tr class="odd" valign="top"><td>mimeType</td><td>"application/x-pdf"</td></tr>
<tr class="even" valign="top"><td>url</td><td>"http://qt.nokia.com/document.pdf"</td></tr>
<tr class="odd" valign="top"><td>argumentNames</td><td>"showTableOfContents" "hideThumbnails"</td></tr>
<tr class="even" valign="top"><td>argumentVaues</td><td>"true" "false"</td></tr>
</table></p>
<p><b>Note:</b> Ownership of the returned object will be transferred to the caller.</p>

<h3 class="fn"><a name="extension" />bool QWebPluginFactory.extension (<i>self</i>, <a href="qwebpluginfactory.html#Extension-enum">Extension</a>, <a href="qwebpluginfactory-extensionoption.html">ExtensionOption</a> <i>option</i> = None, <a href="qwebpluginfactory-extensionreturn.html">ExtensionReturn</a> <i>output</i> = None)</h3><p>This virtual function can be reimplemented in a <a href="qwebpluginfactory.html">QWebPluginFactory</a> subclass to provide support for extensions. The <i>option</i> argument is provided as input to the extension; the output results can be stored in <i>output</i>.</p>
<p>The behaviour of this function is determined by <i>extension</i>.</p>
<p>You can call <a href="qwebpluginfactory.html#supportsExtension">supportsExtension</a>() to check if an extension is supported by the factory.</p>
<p>By default, no extensions are supported, and this function returns false.</p>

<p><b>Note:</b> Currently, this function is only called when JavaScript programs access the global <tt>plugins</tt> or <tt>mimetypes</tt> objects.</p>
<a name="//apple_ref/cpp/instm/QWebPluginFactory/refreshPlugins" />
<h3 class="fn"><a name="refreshPlugins" />QWebPluginFactory.refreshPlugins (<i>self</i>)</h3><p>This function is called to refresh the list of supported plugins. It may be called after a new plugin has been installed in the system.</p>
<a name="//apple_ref/cpp/instm/QWebPluginFactory/supportsExtension" />
<h3 class="fn"><a name="supportsExtension" />bool QWebPluginFactory.supportsExtension (<i>self</i>, <a href="qwebpluginfactory.html#Extension-enum">Extension</a>)</h3><p>This virtual function returns true if the plugin factory supports <i>extension</i>; otherwise false is returned.</p>
