Gtk 3.0 : fenêtre avec treeview dans un expander
En python avec Gtk 3.0, j'essaye d'obtenir une fenêtre avec un notebook. Dans ce notebook, il y a des expanders. Chaque expander contient un treeview.
Après plusieurs tentative, j'obtient ce code :

Gtk.main() |
Je n'arrive pas à afficher le treeview dans l'expander. Mais sans l'expander le treeview s'affiche correctement
Je travail sur une Ubuntu 12.04 et je lance mon programme en utilisant la commande "python ihm.py"
Quelqu'un saurait ou j'ai fait l'erreur car je ne trouve pas...
