QtConcurrent-BlockingMap-Member-Function-of-iterated-objects

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

#include <QtConcurrentMap>
#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;
}
