QT: Error trying to store QString in std::pair

Question

I'm trying to store a QString and a bool in a vector as a pair. I keep getting the error

no matching function for call to 'make_pair(bool, QString&)' messages.push_back(make_pair(true, message));

when I run following function:

void Class::setMessage(){
    QTime time = QTime::currentTime();
    QString message = time.toString() + "-" + "My message";
    vector<pair<bool,QString>> messages;
    messages.push_back(make_pair<bool,QString>(true, message));
}

Whats missing in my code?

You realize that `messages` will only exist for the scope of this function, right? — Rob K, Aug 07 '14 at 18:34

This should work. You don't need to specify the template parameters. They're deduced. I'm assuming you're using std. Perhaps qualify make_pair with std. Remember to include utility.

Also, make sure that the names used are declared the expected scope.

you are right about specifying the template again. That was the problem. Thanks for the help! – isADon Aug 07 '14 at 18:45
