The second connects the thread's started() signal to the processing() slot in the worker, causing it to start. Then the clean-up: when the worker instance emits finished(), as we did in the example, it will signal the thread to quit, i.e. shut down. We then mark the worker instance using the same finished() signal for deletion. Qt for Beginners - Qt Wiki This section can be skipped for now if you only want to program with Qt. Just know that you need to put SIGNAL and SLOT around the signals and slots while calling connect. If you want to know how Qt works, it is better to read this. The Meta Object.

Signals and Slots in Qt5 - Woboq As you might have seen in the previous example, the slot was just declared as public and not as slot. Qt will indeed call directly the function pointer of the slot, and will not need moc introspection anymore. (It still needs it for the signal) But what we can also do is connecting to any function or functor: 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. 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: работаем с сигналами и слотами. Этот "классический" слегка доработанный пример на сигналы и слоты в QT показывает, как их соединять, как разрывать и возобновлять соединение.Слоты (slots) — это методы, которые присоединяются к сигналам.
Signals and slots is a language construct introduced in Qt for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code. The concept is that GUI widgets can send signals containing event information which can be received by other widgets...

Connect Qt QML and C++ Overview. This program demonstrates how QML and C++ can be connected through Qt signals and slots. It does this through embedding C++ code as a context property in QML rather than explicitly connecting signals and slots. When the program is started, the C++ part send a signal to QML, including a parameter.
