You can use standard Qt API to make items non-editable. Maybe you can try clearing the Qt::ItemIsEditable flag in the tree view item.

thanks, I rewrote the qMRMLSubjectHierarchyModel: : subjectHierarchyItemFlags method implements this function, but I don’t know where the model set to the treeview is correct

It looks good. Just to improve style and readability, I would add handle the editable flag in a separate `if` branch.
