This demonstrates how to call a member function on each item in the container and get a collection of the return values.

  1. include <QtConcurrentMap>
  2. include <QVector>
  3. include <iostream>

class MyClass { public:

 float Test() const { // Note, this function MUST be const!
  return 1.0f;


int main() {

QVector<MyClass> v;
MyClass a;
QVector<float> result = QtConcurrent::blockingMapped<QVector<float> >(v.begin(), v.end(), &MyClass::Test);
return 0;
