Qt5 C++ GUI Programming Cookbook - Second Edition

How to do it...

We will continue to use the code from the previous example project since we have already established a working program with multithreading:

1. Open up myworker.h and add the following header:

#include <QObject>#include <QDebug>#include <QMutex>

2. Then, we will add two new variables and make some changes to the class constructor:

public:    explicit MyWorker(QMutex *mutex);    int* myInputNumber;    QMutex* myMutex;signals:    void showResults(int res);    void doneProcess();

3. After that, open up myworker.cpp and change the class constructor to look like the following code. We no longer require the parent input since the object will not have a parent:

MyWorker::MyWorker(QMutex *mutex) {    myMutex = mutex;}

4. We will also change the process() ...
