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".

Hi,
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?
