How to use "Simple Tree Model" Example?

[ChrisW67]

"The Simple Tree Model example shows how to create a basic, read-only hierarchical model to use with Qt's standard view classes."

The example does not provide the necessary mechanisms to modify data in the tree (setData(), insertRows(), insertColumns(), flags()) or advise views of changes/insertions/deletions (numerous signals).

Ahh, makes sense. So the "Editable Tree Model Example" would be of more help then?
