C++ thread connect in Qt - c++

Question

I am starting to learn threads in the C++11 standard in Qt.I can't include library ,no such of directory For example, I have the following simple code:
#include <QCoreApplication>
#include <thread>
#include <iostream>
using namespace std;
void func();
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
MyThread th1;
th1.run();
return a.exec();
}
void func()
{
cout << "This string from thread!"<<endl;
}
On the second string of the code, I have an error. The compiler doesn't "see" , I know that i must "include" 11 standard, so i go to .pro and paste CONFIG += c++11, but it isn't helping me :C
Please, I need your help!

Answer 1

You try to use QThread subclass, but you said that you want to use C++11 thread so use this:
#include <thread>
#include <QDebug>
#include <QApplication>
#include <iostream>
void foo()
{
std::cout << "This string from thread!"<<endl;
//while(true)
//{
// qDebug() <<"works";
// Sleep(500);
//}
}
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
std::thread t(foo);
t.join();
return a.exec();
}
Also next is wrong:
MyThread th1;
th1.run();
Should be:
MyThread th1;
th1.start();
