Hi,
Thanks for the pointer (guess I already read it while searching). The
second answer is what I'm currently heading toward but that's quite
cumbersome

I have seen that problem before:

Unfortunately no answer there too.
I'm not sure what are you talking about. But what about
beginInsertRows() and endInsertRows()? Between this methods you should
add new data, and this data can has child rows.
What is the problem?

Hi list,
I'm currently designing an application which presents its data in a
tree. I have a QAbstractItemModel making a bridge between these data
and the view, so far so good.
However I'm stuck when it comes to react to underlying data structure
changes, specifically when rows are added and removed. Model has to
react before and after the row is added, however, the only information
it gets is "row added" signal. Worse, adding a row can add the row and
some subitems (some objects creates mandatory children).
What is the proper way to deal with this? Should I have some kind of
proxy between the data and the mode?
