Connect receiver to sender for signal.

Arguments:

    receiver
        A function or an instance method which is to receive signals.
        Receivers must be hashable objects.

        If weak is True, then receiver must be weak referenceable.

        Receivers must be able to accept keyword arguments.

        If a receiver is connected with a dispatch_uid argument, it
        will not be added if another receiver was already connected
        with that dispatch_uid.

    sender
        The sender to which the receiver should respond. Must either be
        of type Signal, or None to receive events from any sender.

    weak
        Whether to use weak references to the receiver. By default, the
        module will attempt to use weak references to the receiver
        objects. If this parameter is false, then strong references will
        be used.

    dispatch_uid
        An identifier used to uniquely identify a particular instance of
        a receiver. This will usually be a string, though it may be
        anything hashable.
