[Interest] QObject.destroyed() not working?!

[Alexandru Croitor]

Hi,

I'm going to assume this is with PyQt.

Aside from what Thiago already mentioned, you could try to connect a method declared outside of the class scope.
So something like:

def myDestructor(obj):
  pass

class MyClass(object):
  def __init__(self):
  self.destroyed.connect(myDestructor)

Also do take into account that a Python object's destructor aka __del__ method might not be executed if the object is part of a cycle, due to the garbage collector not knowing the order in which destructors should be called.
I believe starting with Python 3.4, finalizers are always called.
