You're expected to set it as a class property::
class A:
SomethingHappened = signal()
Declared this way, it can be used on class instances
to connect signal observers::
a = A()
a.SomethingHappened.connect(func)
and emit the signal::
a.SomethingHappened()
You may pass any parameters to the emiting function
- they will be forwarded to all subscribed callbacks.
