def on_get_iter(self, path):
try:
self.list[path[0]]
return path[0]
except IndexError:
return None
I changed the code that way and now it works with the first
"on_iter_nth_child" I wrote. I still have a little doubt, the
references says that the methode on_get_iter should raise a ValueError
exception if the path is not valid. Should I add a "raise ValueError"
before the "return None" line?

I also modified this method in that way:
def on_get_path(self, rowref):
return tuple([rowref])
cause rowref should be a list index, but "tuple" requires an iterable
item.
And I left this method unchanged

Do you think the code is correct now?
