Implementing signals and slots

[nikhil-sethi]

I'm trying to implement a custom signal and slot but there seem to be a few errors.
I can't inherit from QObject(which seems to be the recommended way) as it doesn't exist. This example throws:
AttributeError: module 'PythonQt.QtCore' has no attribute 'QObject'
The discussion here doesn't seem to be resolved either.

If I do it without classes like so:

from PythonQt.QtCore import Signal
def slot():
    print("something")
sig = Signal("QVariant") # also tried without QVariant
sig.connect(slot)
sig.emit()

It results in a crash due to segmentation fault.
I'm new to Qt itself so would love any suggestions/right way of doing things. Thank You.
