Hi.
I answer:
modify this:
self.b1.bind('<Alt_L><o>', lambda e, widget=self:one(widget))
self.b2.bind('<Alt_L><t>', lambda e, widget=self:two(widget))
self.b3.bind('<Alt_L><h>', lambda e, widget=self:three(widget))
for this:
self.root.bind('<Alt_L><o>', lambda e, widget=self:one(widget))
self.root.bind('<Alt_L><t>', lambda e, widget=self:two(widget))
self.root.bind('<Alt_L><h>', lambda e, widget=self:three(widget))
Regards.
Cristian Abarzúa F.
