Tasks that use signal/slots and therefore need the event loop. Use: QtConcurrent and QThreadPool + QRunnable. Specifically, the tasks that are not using signal/slot mechanism during the task execution. However, there are other important criteria: Picking the right tool can be challenging at first, but in fact, the decision tree consists of just two options: you either want Qt to manage the threads for you, or you want to manage the threads by yourself. The Qt framework offers many tools for multithreading. Choosing between using QThreadPool and QThread A reader is expected to have previous background in Qt and C++ to understand the content. The goal of this article is to aggregate the essential knowledge about concurrent programming with the Qt framework, specifically the most misunderstood topics. Multithreading can also be applied to one process to enable parallel execution on a multiprocessing system. The threaded programming model provides developers with a useful abstraction of concurrent execution. These threads share the process’ resources but are able to execute independently.

Multithreading is a widespread programming and execution model that allows multiple threads to exist within the context of one process. Nevertheless, picking the right and working solution from a dozen different answers is fairly non-trivial, especially given that each solution comes with its own drawbacks. To your credit, you don’t give up and find yourself scouring StackOverflow.

C++ developers strive to build robust multithreaded Qt applications, but multithreading was never easy with all those race conditions, synchronization, and deadlocks and livelocks.
