-Qt/WebKit supports loading of netscape plugins. To enable loading of plugins, you must enable QWebSettings::PluginsEnabled. 
+Qt/WebKit supports loading of two kinds of plugins. 
+ * Qt based plugins - These can be QWidget or QGraphicsWidget based.

+<object> are encapsulated in HTMLPlugInElement. FrameLoaderClient has a method createPlugin that returns the Widget that should be used as the plugin. FrameLoaderClientQt.cpp inspects the mimetype. With a mime type of application/x-qt-plugin or application/x-qt-styled-widget, the frameloader creates a QWidget using the QWebPluginFactory (QWebPluginFactory::create()). This QWidget is encapsulate in a QtPluginWidget (which is basically a WebCore Widget). The QWidget is created as a child of the QWebPageClient::pluginParent() (more information on this below).

-QWebPageClient - We require access to the QWidget (QGraphicsView/QWebView) or the parent (QGraphicsWebView/QWebView). To provide this and keep the plugin code working in both cases, the chrome (hostwindow) provides a platformPageClient() that helps us get information about the client of the QWebPage. Both QWebView and QGraphicsWebView provide objects that implement the virtuals in QWebPageClient.

QWebPageClient::pluginParent() returns the parent QObject (i.e QWebView or QGraphicsWebView). The ownerWidget() is necessary for the popup code. The  pluginParent is necessary to position the plugins.
