Signals and Slots. In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal.
Qt Toolkit - Signals and Slots The signal/slot mechanism is a central feature of Qt and probably the part that differs most from other toolkits. In most GUI toolkits widgets have a callback for each action they can trigger. This callback is a pointer to a function. In Qt, signals and slots have taken over from these messy function pointers.

Traditional syntax: SIGNAL and SLOT() QtCore.SIGNAL() and QtCore.SLOT() macros allow Python to interface with Qt signal and slot delivery mechanisms. This is the old way of using signals and slots. The example below uses the well known clicked signal from a QPushButton.The connect method has a non python-friendly syntax.
Signals are emitted by objects when they change their state in a way that may be interestingSignals and Slots (registering callbacks) If a served object exposes a Qt signal (or Qt-like signals), you can connect a slot to it in the proxy.My favorite Qt feature is the Signal/Slots mechanism.
