Using a signal / slot pattern for parts ?

[s-celles]

Hello,

I wonder if a signal / slot mechanism shouldn't be more "user friendly".

For example we could write:

    class MyApp(object):
        def __init__(self):
            ...
            self.switch.pressed.connect(self.do_it_when_pressed)

instead of

    class MyApp(object):
        def __init__(self):
            ...
            self.switch.set_callback_up(self.do_it_when_pressed)

Some signal / slot library are

An other pattern to consider may be Pub / sub
