J'ai un TreeView et quand je clique dedans, je reçois l'erreur:PyGtk - TreeView et ligne sélectionnée
Traceback (most recent call last):
File "pyparty.py", line 76, in get_selected_user
self.selected_user = tree_model.get_value(tree_iter, 0)
TypeError: iter must be a GtkTreeIter
Il arrive juste pour le premier clic. Après ça ça fonctionne bien. Je ne sais pas ce qui ne va pas. Voici le code:
