For normal buttons this is always False, so our first slot ignored this data. However, we can make our button checkable and see the effect. In the following example, we add a second slot which outputs the checkstate. python class MainWindow(QMainWindow): def __init__(self): super()....
The differentiation between signals/slots is now only important if you work with qml and you want to listen on a signal in qml (to receive go function calls) or if you want to call a go function (slot) from qml. Maybe take a look here for some qml example which shows you how to ...

The saturate bit is set one full cycle (one delay slot) after a saturate occurs. This bit will not be modified by a conditional instruction whose condition is false. Endian bit. This bit is read-only. Depicts the device endian mode. 0 = Big Endian mode. 1 = Little Endian mode [...
