QTreeView: How to create objects from root items?

[anda_skoa]

Given a QTreeView that is supplied with a QStandardItemModel is it possible to create an object out of each root item in the model where all parent items linked to each root are contained in the created object?

No idea what you mean.
Maybe provide an example of the tree and the desired result?

Furthermore, given a QTreeView set up with a model is it possible to save or access all data within the model

1) You start with the invalid model index.
2) You ask the model for the row count using that index
3) You iterate over the range from 0 to row count, asking the model for the index with the model index you already have as a parent
4) You recurse with the new index, go to (2)
