Just add an argument to __init__() of the one class where you will pass
the instance of the other class to it. Then you can store it inside the
instance, and use it whenever needed.
class foo(object):
def __init__(self):
pass
def some_method(self):
print ("Hello from foo.some_method")
class bar(object):
def __init__(self, foo_instance):
self.foo_instance = foo_instance
def some_method(self):
foo.some_method()
a=foo()
b=bar(a)
Of course since you're dealing with PyQt your classes will involve some
other parameters to __init__ but you can still tack your parameter on there.
You may want to re-examine how you're building your classes, though.
There's likely a way you can structure things to eliminate this kind of
coupling, especially in the context of a GUI. Often times making your
own signal that can be externally connected to a method of the other
class is the way to go as this reduces the coupling between the classes.
