Qt signals and slots multithreading

The article, Multithreading Technologies in Qt, compares the different approaches. The rest of this article demonstrates one of these methods: QThread + a worker QObject. This method is intended for use cases which involve event-driven programming and signals + slots across threads. Usage with Worker class Multithreading with Qt | Packt Hub Understanding the QThread framework in depth The worker model and how you can offload a process from the main thread An overview of all the available threading technologies in Qt Qt provides a sophisticated threading system. We assume that you already know threading basics and the associated issues ...

Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type. Multithreading Technologies in Qt | Qt 5.12 For convenience, QFutureWatcher enables interactions with QFutures via signals and slots. Qt Concurrent's map, filter and reduce algorithms automatically distribute computation across all available processor cores, so applications written today will continue to scale when deployed later on a system with more cores. Threads and QObjects | Qt 5.12 An event loop in a thread makes it possible for the thread to use certain non-GUI Qt classes that require the presence of an event loop (such as QTimer, QTcpSocket, and QProcess). It also makes it possible to connect signals from any threads to slots of a specific thread.

Deeper. Widgets emit signals when events occur. For example, a button will emit a clicked signal when it is clicked. A developer can choose to connect to a signal by creating a function (a slot) and calling the connect() function to relate the signal to the slot.
