QList<int> from qml

Marek

Hi
I have simple QList<int> which I'm passing to QML with this property:

Q_PROPERTY(QList<int> days MEMBER m_days NOTIFY daysChanged)

Now I have some function on C++ side to retrieve what has changed on QML side

Q_INVOKABLE void setSchedData(QString role,QVariant value);

I thought it should work stright away, because Qlist<int> is changed to Array when passing to QML and array is changed to QVariantList when going back to C++
But this piece of QML code made me some headache:

 var tmp_days=Array.from(WateringSchedModel.days)
//for(var i=0;i<WateringSchedModel.days.length;i++) {
//    tmp_days.push(WateringSchedModel.days[i])
//}
tmp_days.push(index_role)
WateringSchedModel.setSchedData("days_role",tmp_days)

it works only with Array.from(exposed_from_cpp) or when I copy elements of days property to tmp_days (commented out), when I use Array.isArray(WateringSchedModel.days) it says false, typeof says object, simply writing:

var tmp_days=[];
tmp_days=WateringSchedModel.days

does not work, however I can iterate through tmp_days as if it has been an array, what Am I missing here ?
Best,
Marek
