Set html <style> with QWebElement

[poser]

I’m trying to add a default style to every rendered webpage in my browser. I’ve tried many different things and can’t get the DOM to change. I’m using Qt 4.7.0 on Windows with VS. I believe the following should work, but the DOM doesn’t get modified. Any thoughts?

void QWebView::onLoadFinished(bool error)
{
        QWebElement style;
        style.setOuterXml("<style>*:focus{outline:1px solid red}</style>");
        style.setAttribute("type", "text/css");
        page()->mainFrame()->findFirstElement("head").appendInside(style);
}

void QWebView::onLoadFinished(bool error)
{
        QWebElement style;
        style.setOuterXml("<style>*:focus{outline:1px solid red}</style>");
        style.setAttribute("type", "text/css");
        page()->mainFrame()->findFirstElement("head").appendInside(style);
}
