Working with QRunnable processes

In this recipe, we will learn how to use another type of high-level method to easily create a multithreading Qt 5 application. We will be using the QRunnable and QThreadPool classes in this recipe.

How to do it...

Let's get started by performing the following steps:

1. Create a new Qt Widgets Application project and create a new C++ Class called MyProcess, which inherits the QRunnable class.
2. Next, open up myprocess.h and add the following headers:

#include <QRunnable>
#include <QDebug>

3. Then, declare the run() function, as follows:

class MyProcess : public QRunnable {
public:
    MyProcess();
    void run();
};

4. After that, open up myprocess.cpp and define the run() function:
