Hi Thomas,
thank you for the answer. I could change my code to implement this. But
the QML UI should never request data for item with index -1. Such item
doesn't exist. There should be two items with indexes 0 and 1.
So even if I changed my code so that it returns None, I would only
eliminate the error message, but it wouldn't solve my problem. I will
still get empty delegates.
Regards,
Vladimir

Hi Vláďa,

[...] I think the most important information is that QML
requests from QAbstractListModel item with index -1, which of course doesn't
exist.
In that case, your model should return None (in C++ one would return
an empty/invalid(?) QVariant.
HTH.
Thomas
