Yes but how can be achieved such a feature?

I used a to much simpliefied method, now I completed the method in this
way:
def on_iter_n_children(self, rowref):
if rowref:
return 0
return len(self.list)
to respect the description of iter_n_children ... but the code is still
to slooooooow.
And while it is building the model I receive this error sometimes:
** (xpn.py:3194): CRITICAL **: file pygtktreemodel.c: line 718
(pygtk_generic_tree_model_unref_node): assertion `VALID_ITER(iter,
tree_model)' failed
