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. |
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>
- 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;
}
