Yes, I think it's that difficult. But the row number should not be
useful anyway, because the TreeModel is iterator based. It's the same as
wanting to get the numerical index of a std::list. 

You might parse the Path after converting the iterator to the path. It's
probably very slow though.

If what you actually want is some identifier for the data in the column,
then just store an extra hidden ID column in the model.
