Each PyQt widget, which is derived from QObject class, is designed to emit ‘signal’ in response to one or more events. The signal on its own does not perform any action. Instead, it is ‘connected’ to a ‘slot’. The slot can be any callable Python function. In PyQt, connection between a signal and a slot can be achieved in different ways.

QT framework is a great application stack that allows for cross development (between different OS’s) without having to re-do the code for e.g.Linux/WindowsI shall go into more detail with SIGNAL’s and SLOT’s in the next tutorial for QT development, but in essence they are defined within the class of the... c++ - Сигналы и слоты в приложении Qt console

Qt Signal Tools. qt-signal-tools is a collection of utility classes related to signal and slots in Qt. It includes: QtCallback - Package up a receiver and slot arguments into an object for invoking later. QtSignalForwarder - Connect signals and events from objects to QtCallback or arbitrary functions.
