How do I develop a plug-in for QtWebKit?

I am trying to develop a plug-in for QtWebkit. But I am not able to find how to develop a plugin for QtWebKit, hopefully one that can be invoked by JavaScript. Does anyone know of any tutorials or documents that explain how to do this?

Webkit has been intregated into Qt and this integrated package is called QtWebkit. They have provided new method for for plugin creation.

The simple answer is to write a subclass of QWebPage and set this on your webview. Then you can show your own HTML page and react to the appropriate object tag in the createPlugin method;

protected:
   QObject* createPlugin(const QString &classid, const QUrl &url, const QStringList &paramNames, const QStringList &paramValues)
   {
      if (classid=="lineedit") {
         QLineEdit *lineedit = new QLineEdit;
         return lineedit;
      }
      return 0;
}

and show something like the following HTML;

<object type="application/x-qt-plugin" classid="lineedit" id="lineedit">
can't load plugin
</object>

Remember you need to turn on plugins, and possibly also JavaScript if you want more advanced functionality in the QWebSettings

To have more advanced functionality, you should use a QWebPluginFactory

To expose the object to Javascript, use

this->mainFrame()->addToJavaScriptWindowObject("lineedit", this);

where lineedit is the name that can be used to access the object from javascript

Qt properties will be exposed as JavaScript properties and slots as JavaScript methods. (see http://doc.qt.io/archives/qt-4.7/qwebframe.html#addToJavaScriptWindowObject)

Introduction to WebKit Plug-in Programming Topics is for WebKit, is QtWebKit that special?
