This article may require cleanup to meet the Qt Wiki's quality standards. Reason: Auto-imported from ExpressionEngine. Please improve this article if you can. Remove the {{cleanup}} tag and add this page to Updated pages list after it's clean. |
Demonstrates how to pass each object in the container to a member function of different class instance. You can alternatively do this using boost::bind
- include <QtConcurrentMap>
- include <QVector>
- include <boost/bind.hpp>
- include <iostream>
class Object{};
class MyClass
{
public:
float operator()(const Object& object) { return 1.0f;}
typedef float result_type;
};
int main()
{
QVector<Object> v;
Object a;
v.push_back(a);
MyClass myClass;
QVector<float> result = QtConcurrent::blockingMapped<QVector<float> >(v.begin(), v.end(), myClass);
std::cout << result[0] << std::endl;
return 0;
}
