This demonstrates how to call a member function on each item in the container and get a collection of the return values.<br /><code><br />#include &lt;QtConcurrentMap&amp;gt;<br />#include &lt;QVector&amp;gt;

#include &lt;iostream&amp;gt;

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

int main()<br />{<br /> QVector&amp;lt;MyClass&amp;gt; v;<br /> MyClass a;<br /> v.push_back(a);

QVector&amp;lt;float&amp;gt; result = QtConcurrent::blockingMapped&amp;lt;QVector&amp;lt;float&amp;gt; &gt;(v.begin(), v.end(), &amp;MyClass::Test);

return 0;<br />}
