Using threads

Qt 6 provides multiple methods to create and use threads. You can choose between high-level methods and low-level ones. High-level methods are much easier to get started but are limited in what you can do with them. Conversely, low-level methods are more flexible but not beginner-friendly. In this recipe, we will learn how to use one of the high-level methods to easily create a multithreading Qt 6 application.

How to do it…

Let’s learn how to create multithreading applications by following these steps:

  1. Create a Qt widget application and open up main.cpp. Then, add the following headers at the top of the file:
    #include <QFuture>
    #include <QtConcurrent/QtConcurrent>
    #include <QFutureWatcher>
    #include <QThread>
    #include <QDebug>
  2. Then, create a function called printText() before the main() function:
    void printText(QString text, int count) {
        for (int i = 0; i < count; ++i)
       ...
