You can connect as many signals as you want to the same slot. (But indeed you will need to connect the 16 signals individually. ).
You can connect all signals to the same slot, and then you can get the sender with the QObject. Sender method. Or you better look at the QSignalMapper class.
You can make a list from your QSpinBox's, and use a for loop for that: for box in mySpinBoxes: box.valueChanged. Connect(self. MyFunction).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
