Hi
Thanks for your answer
I know about xxxInsertRow but these are meant to be called by the
model (or at least by a class that has knowledge of the model). The
question is how to properly call it when the only notification you
get from the data is "this row was added|removed".
You can use signal/slot mechanism to notify your model. I can't
understand what is the problem. There are different solutions. Where
you receive this notification?
That's what I do, but the signal says childAdded, where model needs
childWillBeAdded and childHasBeenAdded to handle
beginInsertRows/endInsertRows, same for the removal so that's not
working. Worst case is for the removal, since beforeRemoveRows triggers
accesses to the to-be-removed rows you can run into serious issues if
the child has been delete'd
