Therefore it is not usually necessary to use QtCore.SLOT() for Qt slots. However, doing so is more efficient as it avoids a conversion to Python and back to C++. Qt allows a signal to be connected to a slot that requires fewer arguments than the signal passes. The extra arguments are quietly discarded. PyQt4 slots can be used in the same way. New-style Signal and Slot Support — PyQt 4.11.4 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. QML Signal and Handler Event System | Qt 4.8 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.
