Problème d'import de fichier

**sluke** · 08/03/2011, 16h26

Bonjour,

En voulant créer un assistant tout bête, je me suis retrouvé face à une erreur plutôt étrange.
Mon programme se divise en 4 fichiers :
- main.py (le lanceur)
- Window1.py (ma première fenêtre d'assistant)
- Window2.py (ma seconde fenêtre d'assistant)
- windows.ui (fichier glade)

La première fenêtre s'affiche, je clique sur 'Suivant'.
La seconde fenêtre s'affiche pendant que la première est détruite.
Et là, je clique sur 'Précédent' pour revenir sur la première fenêtre :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Window2.py, line 27, in button_prev_clicked
window1 = Window1(self.gtkfile)
NameError: global name 'Window1' is not defined

Si quelqu'un voit d'où ça peut venir...

D'avance merci
