No ideas on this one?

One additional question:
You wrote, that internalPointer() is not meant to be used outside of the
model. But how would I get the associated object from a QModelIndex?
I am using selectedIndex() on the view to get the indexes, but how to
proceed from there on?

Hello,
I finally was able to compile an example case, which is not too
complex,
please find it attached. Run the python script, expand one LevelOne
item
and select a LevelTwo item and in the menu choose add/edit levelthree.
If
you do this you should see an error or the interpreter will crash (try
adding more items und expand them!). As said this error can be
prevented
by adding strong references for all items in the tree (which is
something
the createIndex obviously does not). Uncomment line 210 and 211 to see
that adding all items to a list helps.
The root item is owned by the model, so this should work, right?!
The root item is owned by the model, but does the root item own all of
its
children, grandchildren etc.? I can see that it owns its children
because
you explicitly call its appendChild() method, but I'm not clear where
the
children's equivalent methods are called. Have you tried printing out
the
tree of items starting with the root item at various point to make sure
the
tree contains what you think it should?
QAbstractItemModel won't maintain your model for you. As the
documentation
says, it "provides the abstract interface for item model classes" - the
key
word being "interface". It is not the container of the model data -
that's
the responsibility of a sub-class.
