PyQT中多重继承,其中继承的父类有QObject或QObject的子孙类

super(Child, self).__init__()

from PyQt5.QtCore import  QObject
class Parent_1:
    def __init__(self):
        print(‘Parent_1.__init__‘)
        
class Parent_2(Parent_1):
    def __init__(self):
        super(Parent_2, self).__init__()
        print(‘Parent_2.__init__‘)
        
class Parent_3:
    def __init__(self):
        print(‘Parent_3.__init__‘)      

class Child_2( QObject , Parent_2,Parent_3):
        def __init__(self):
            #QObject.__init__(self) 
            super(QObject, self).__init__()
            #super(Child_2, self).__init__()
            
if __name__ == ‘__main__‘: 

    import sys
    from PyQt5.QtWidgets import QApplication
    app = QApplication(sys.argv)  
 #####################################################   

    
    print(‘---------------------------‘)
    child_2 =     Child_2()    
  #####################################################   
    sys.exit(app.exec_())
