When a signal is connected to a method, the method is automatically invoked whenever the signal is emitted. (In Qt terminology, the method is a slot that is connected to the signal; all methods defined in QML are created as Qt slots.) This enables a signal to be received by a method instead of a signal handler. New-style Signal and Slot Support — PyQt 4.12.3 Reference ... The code (or component) that emits the signal does not know or care if the signal is being used. The signal/slot mechanism has the following features. A signal may be connected to many slots. A signal may also be connected to another signal. Signal arguments may be any Python type. A slot may be connected to many signals. Copied or Not Copied: Arguments in Signal-Slot Connections? The conclusion from the above results is that we should pass arguments to signals and slots by const reference and not by value. This advice is true for both direct and queued connections. Even if the sender of the signal and the receiver of the slot are in different threads, we should still pass arguments by const reference. How Qt Signals and Slots Work - Woboq
