How to implement nested editable lists in C++ as models in Qt (QML oriented)

[wysota]

Ok, I tried to implement it as QAbstractListModel,

Why not QAbstractItemModel?

Why not QAbstractItemModel?

Because it looked easier (I hadn't idea why I need QAbstractItemModel). I had class for List of Lists which was QAbstractListModel and child List which also was QAbstractListModel (which I planned to return as a property through parent's data() method).
Why this is bad? (or why this was bad? I'm going to rewrite it based on responses in this thread)

You want a hierarchical model thus it seems to me implementing a proper model will do the job. I don't think returning a list in each model which will in turn return a list of its own is a better approach.

Why not QAbstractItemModel?

Easier to implement a list with QAbstractListModel at its base.
QAbstractItemModel requires implementations for columnCount(), index() and parent(), the latter two usually not trivial, and neither is needed for a list.

You want a hierarchical model thus it seems to me implementing a proper model will do the job.

Aside from ribtoks data not being hierachical as it turns out, I don't think QtQuick can deal with tree models at this point.

I don't think QtQuick can deal with tree models at this point.

It can deal with tree models with the use of VisualDataModel element which allows to set the root index to traverse different layers of the model within the view.
