Indeed the line

   
myWebKit.page().mainFrame().evaluateJavaScript($(document).ready(function()


{ $(body).css(background, #f00);});)


must be changed to

   
self.webView.page().mainFrame().evaluateJavaScript($(body).css(background, 
#f00);)


With this modification, everything is ok.

Thanks.

QWebFrame's addToJavaScriptWindowObject() method lets you insert an instance
of a QObject subclass into the page. You can expose methods to JavaScript,
but you have to declare them as slots with the @pyqtSignature() decorator.
The example code can be found here:

I'll study it as soon as possible...

I also found a whitepaper of QT. I'll try to test that.

Thanks for showing me the direction.
