[QComboBox] SetCurrentText() donne une attributerror

Bonjour,:)

Dans une fenêtre GUI, j'ai plusieurs listes déroulantes.
Sur elles, j'ai testé les méthodes: [maliste].CurrentItem() ainsi que [maliste].setCurrentText()
mais un message m'indique que l'attribut sélectionné n'est pas valide (attributeerror)

Quelqu'un peut-il m'orienter?

Voici les lignes où j'ai ce problème:

Code:

1
2
self.lst_path.setCurrentText("DEFAULTPATH")
                self.lst_layername.setCurrentText("DEFAULTLAYER")

Voici mon fichier ui:
