Examining Qt's different threading models

Before we start exploring how we can use Qt's thread support, we should understand the support Qt has for threads. Most of Qt's thread support is on the C++ side, but there is also support in QML.

In this section, we will learn about the following Qt thread models:

• Simple Threads
• Thread pools
• Qt Concurrent (run, map, filter, and reduce)
• QML WorkerScript

We will start with simple threading using QThreads.

Simple threads

As Qt has evolved over almost 30 years, its thread support has also evolved. One of the earliest and most simplistic support methods for threading is QThread. QThread encapsulates the idea of a thread and it provides its own event loop. The event loop...
