Thanks for the fast answer.
It still doesn't work.. I know that the value will be an int, but
qdbus_cast<QMap<QString, int > >(ret.arguments().first()); returns a
compiler error.
So I used a QVariant map, which works for the compiler but the result
is useless.

My Code:
    QMap<QString, int> test;
    QVariantMap test2;

    //qdbus_cast<QMap<QString, int > >(ret.arguments().first());
    //qDebug() << qdbus_cast<QMap<QString, QVariant >
>(ret.arguments().first());
    test2 = qdbus_cast<QVariantMap>(ret.arguments().first());
    qDebug() << test2;
    qDebug() << test2.value("download");


The output:

type end_dict_entry not a basic type
type end_dict_entry not a basic type
QMap(("download", QVariant(void*, ) ) ( "upload" ,  QVariant(void*, ) ) )
QVariant(void*, )

Thanks for your help.
