I don't think it's that bad at all. If you have a lot of frames and
children, maybe it is a bit nicer to define widget classes that save you
to explicitely apply the bindings for any of your Frames and their
children, like:
class SLabel(Label):
def __init__(self, *args, **kw):
Label.__init__(self, *args, **kw)
for seq in ('<4>', '<5>'):
if self.master.bind(seq):
self.bind(seq, self.master.bind(seq))
