Bonjour,

Je voudrais me créer un cell editor qui soit une liste déroulante, et pas seulement en lecture seule, et pouvoir gérer les entrées utilisateurs. J'ai trouvé un exemple sur le net qui utilise un combobox, mais en lecture seule (style=wx.CB_READONLY).
Dès lors que j'enlève l'attribut de lecture seule, l'éditeur ne s'affiche plus dans le grid, je ne comprend pas pourquoi, et ça me bloque. Qqun aurait-il une idée d'où ça peut venir ?

Merci d'avance.

Voilà mon code de test :

Code : Sélectionner tout - Visualiser dans une fenêtre à part
