Well, the treeview doesn't know its a table model. (in fact none of the
standard views cares about the specific subclass of QAbstractItemView its
The QAbstractItemView API is the contract between model and view and hence
its whats being used by the views. The QAbstractTableModel is just a
convenience class with some defaults for some of the contract-API from
QAbstractItemView already implemented. You still have to implement the
data,rowCount and columnCount according to the QAbstractItemView contract.
And that means returning a proper rowcount depending on the given index.
You will lose your present job and have to become a door to door mayonnaise
