This demonstrates how to call a function on every object in the collection:

  1. include <QtConcurrentMap>
  1. include <iostream>

class MyClass { public:

void Test()
{
std::cout << "Test" << std::endl;
}

};

int main() {

QVector<MyClass> v;
MyClass a;
v.push_back(a);

QtConcurrent::blockingMap(v.begin(), v.end(), &MyClass::Test);

return 0; }
