Debugging JavaScript code evaluated by QWebView

Hello all,

What's the recommended way of debugging JavaScript code executed within the page loaded from QWebView? I'm aware that something like this could be accomplished:

QVariant result;
result = this->page()->mainFrame()->evaluateJavaScript( "js function.." );

BUT, what about the JavaScript code which runs e.g. after "load(QUrl("page.html"));" , triggered by user interaction?

Any ideas??

Thanks,
