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

#include <QtConcurrentMap>
#include <QVector>

  1. include <iostream>

class MyClass
{
public:
float Test() const // Note, this function MUST be const!
{
return 1.0f;
}
};

int main()
{
QVector<MyClass> v;
MyClass a;
v.push_back(a);

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

return 0;
}
