Pyqt signal slot between classes

By Editor

New signals can be defined as class attributes using the pyqtSignal() factory.Although PyQt5 allows any Python callable to be used as a slot when connecting signals, it is sometimes necessary to explicitly mark a Python method as being a Qt slot and to provide a C++ signature for it.

How to connect pyqtSignal between two different objects (classes) PROPERLY? I mean best practice. Look what I have done to achieve the goal: The Thermometer class is notified when Pot increases its PyQt Signals and Slots - Tutorials Point Each PyQt widget, which is derived from QObject class, is designed to emit ‘signal’ in response to one or more events.
