Qt 5 to-do in QTextHtmlParser

   // set element specific attributes
    switch (id) {
        case Html_a:
            charFormat.setAnchor(true);
            for (int i = 0; i < attributes.count(); i += 2) {
                const QString key = attributes.at(i);
                if (key.compare(QLatin1String("href"), Qt::CaseInsensitive) == 0
                    && !attributes.at(i + 1).isEmpty()) {
                    hasHref = true;
                    charFormat.setUnderlineStyle(QTextCharFormat::SingleUnderline);
                    charFormat.setForeground(Qt::blue); // ### Qt5: QApplication::palette().link());
                }
            }
