QEvent::Drop event is never generated for QQuickView window

I'm struggling with an issue that QEvent::Drop event is never generated for my QQuickView window.

I need to implement a drag'n'drop functionality, to drop files from explorer to the QQuickView.

As described in this post, i've istalled an eventfilter for the QQuickView objet, and in eventFilter() method trying to catch required events. The QEvent::DragMove is being generated as expected, as i drag a file over the view. But when i drop the file on the view, the QEvent::Drop is not being generated. Instead, the QEvent::DragLeave is generated.

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();

    Filter f;
    QQuickView *view = new QQuickView;
    view->installEventFilter(&f);
    view->show();

    return a.exec();
}

And here is a (Event)Filter class code: (header)

class Filter : public QObject
{
    Q_OBJECT
public:
    Filter(){};
    virtual bool eventFilter(QObject *watched, QEvent *event) Q_DECL_OVERRIDE;
};

(source)

bool Filter::eventFilter(QObject *watched, QEvent *event)
{
    if(event->type() == QEvent::DragMove)
        qDebug() << "it's a drag";
    if(event->type() == QEvent::Drop)
        qDebug() << "it's a drop"; // <<-- Never reaches here
    return QObject::eventFilter(watched, event);
}

My colleagues helped me out with this question. Apparently you have to add a DropArea item to your QML root file, and after that the QQuickView will start receiving QEvent::Drop events. I can not find any documentation on this case though, and i also wonder what would be more general solution for this, if you had a QWindow class instead. Anyway, I'm closing this question.
