PyDispatcher question

[Jorgen Bodde]

Hi all,

Hopefully someone can help me. I am fairly new to Python, and I am
looking into PyDispatcher. I am familiar with the C++ sigslot variant,
and I wonder how similar PyDispatches is. I run in to the following
'problem' (pseudo code, untested here)

import pydispatch.disp atcher

class A:
def __init__(self):
dispatcher.conn ect(self.someSi gnal, signal = 1)

def someSignal(self ):
print 'Hello world'

obj = A()

# send a trial signal

dispatcher.send (signal = 1)

>>Hello world

# now for the catch, how to clean up?
# if I do:
obj = None # clean up

dispatcher.send (signal = 1)

>>Hello world

The object still extists... Which is logical, the method is still
bound to the signal, and the object itself is not yet deleted. Is
there an elegant way to delete the object and let the signal unbind
itself? Or do I need to do this in the destructor of the object? AFAIK
there is no real destructor in Python?

Do I need to do it differently? Or is there a better signal mechanism to use?

Any help is appreciated!
