function notifyMe() {
    if (Notification.permission === "granted") {
        var notification = new Notification("Hi there!");
    } else if (Notification.permission !== "denied") {
        Notification.requestPermission(function(permission) {
            if (permission === "granted") {
                var notification = new Notification("Hi there!");
            }
        });
    }
}

<button onclick="notifyMe();">Notify me</button>

QObject::connect(page,
    SIGNAL(featurePermissionRequested(QWebFrame*, QWebPage::Feature)), this,
    SLOT(featurePermissionRequested(QWebFrame*,QWebPage::Feature))
);

...

void Form::featurePermissionRequested(QWebFrame* frame, QWebPage::Feature feature) {
    switch (feature) {
        case QWebPage::Notifications:
            qDebug() << "Notification";
            page->setFeaturePermission(frame, feature, QWebPage::PermissionGrantedByUser);
        break;
        case QWebPage::Geolocation:
            qDebug() << "GEO";
        break;
        default:
            qDebug() << "Unknown feature";
    }
}
