Thanks, David, for you help.
When I change the slot function to what you show in your second
example, I get the same results: nothing. When I change it to what you
have in your first example, I get the following:
Object::connect: No such slot QApplication::map()
Object::connect: (sender name: 'chkProductIngredientsDelete_1')
Object::connect: (receiver name: 'main.py')
Object::connect: No such slot QApplication::map()
Object::connect: (sender name: 'chkProductIngredientsDelete_2')
Object::connect: (receiver name: 'main.py')
Object::connect: No such slot QApplication::map()
Object::connect: (sender name: 'chkProductIngredientsDelete_3')
Object::connect: (receiver name: 'main.py')
Object::connect: No such slot QApplication::map()
Object::connect: (sender name: 'chkProductIngredientsDelete_4')
Object::connect: (receiver name: 'main.py')
Object::connect: No such slot QApplication::map()
Object::connect: (sender name: 'chkProductIngredientsDelete_5')
Object::connect: (receiver name: 'main.py')
Object::connect: No such slot QApplication::map()
Object::connect: (sender name: 'chkProductIngredientsDelete_6')
Object::connect: (receiver name: 'main.py')
