Class Signal

        Signal

A signal object implements the observer pattern. It can be connected to any number of slots (i.e. callbacks). Whenever the signal is called, all the slots are called.

The return value of this function will depend on the combiner. The combiner takes a generator of slot results and returns a value. The slots whose results are not evaluated are not called.

__init__(self, combiner=<function default_combiner at 0x101bc62a8>, sender=None, *a, **k)
(Constructor)

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__
(inherited documentation)

connect(self, slot, in_front=False, sender=None)

source code 

Connects the signal to the slot. Does nothing if the slot is already connected. Returns the wrapper object that is used as a slot.

If 'in_front' is True, the slot will be put first, meaning it will be called before previously registered slots (by default it is put last).

If 'sender' is not None, it will be passed as last ordinal parameter to the slot when the signal is dispatched.
