bonjour
je voudrais que la scroll region soit décalée plus en haut et à gauche au lancement, ici la scroll region part de (0,0) du canvas, je voudrais par exemple avoir (-50,-50) en haut à gauche au départ, comment changer ça?

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

        try:
            self.master.config(menu=self.menubar)
        except AttributeError:
            # master is a toplevel window (Python 1.4/Tkinter 1.63)
            self.master.tk.call(root, "config", "-menu", self.menubar)
 
 
root = Tkinter.Tk()
root.geometry("+300+300")
Tester(root)
root.mainloop()

j'ai essayé la methode .set(lo,hi) mais c'est sans effet
