How to pass keyPressEvent in Qt to base class?


If you reimplement this handler, it is very important that you call the base class implementation if you do not act upon the key.

return QWidget::keyPressEvent(k);

That's what "call the base class implementation" means.

Class Inheritance, using Child Class to set up Parent Class
It's good practice to call the super-init-method, so I would suggest: class Character(): 'Common base class for all characters' def __init__(self, attack, defence, strength): self.attack = attack self.defence = defence self.strength = strength class Enemy(Character): 'Enemy Class' def __init__(self): Character.__init__(self, attack=random.randint(

Python class inside subclass inheriting from class inside parent class
To inherit from the class you specified, according to the code you provided, all that is required is to define the class personality_2 like this: class SocialDog(Dog): #... class personality_2(Dog.personality_1): #... Now, as for your problem when trying to use super(), this might be because your base classes of Dog and Dog.personality_1 do not inherit from the python default class
