Unsolved WebView and eventFilter

[Skroopa]

Tried to place WebView inside/outside (and many other combinations) MouseArea and Flickable - no events are sending, if I tap on WebView. Also Flickable don't flick on Android, but on Windows all works properly. Is there possible way to catch touch/mouse down events, when I interact with WebView on Android?
Only thing, what I need, that user touches on the screen, when WebView is in fullscreen mode.
I wrote some code for handling eventFilter:

bool MousePressEvent::eventFilter(QObject *o, QEvent *e) {
    if(e->type() == QEvent::MouseButtonPress) {
        qDebug() << "touch!";
        QMetaObject::invokeMethod(socialNetworkAuthMenu, "showBottomTools");
        emit clicked();
    }
    return QObject::eventFilter(o, e);
}

On Windows, if WebView in fullscreen mode, clicked() emited properly, but on Android - no effect, eventFilter simply not working.
Is it possible to catch QEvent::MouseButtonPress or QEvent::TouchBegin events on Android when WebView in fullscreen mode?
