Reverse iterate on QMultiMap

[Josz]

Hello, maybe its a very treated theme, but in moment I coud not find a satisfactory answer in google.

I have the next QMultiMap List:

    QMultiMap<QString, QString> data;
    data.insert("John", "Young");
    data.insert("John", "Tall");
    data.insert("Mike", "Short");
    data.insert("Mike", "Good man");
    data.insert("John", "Clueless");
    data.insert("Mike", "Long hair");

    for(const QString &name : data.uniqueKeys()){
        QStringList aux = data.values(nombre);
        qDebug() << "Name: " << name;

        for(const QString &aux2 :  aux) {
            qDebug() << aux2;
        }
    }

The code produces the next output

Name:  "John"
"Clueless"
"Tall"
"Young"
Name:  "Mike"
"Long hair"
"Good man"
"Short"

The list is in The list is in random order displayed.

Is there a way to show the elements in reverse order? .... Or in a determined order, for example, alphabetical?

Thanks in avance.

@Josz
I assume you mean the "multi-items" associated with each key in reverse order. Then don't use for(const QString &aux2 : aux) : use a reverse iterator, or count down from aux.length() - 1 yourself, or reverse the QStringList.

@JonB
thank you john! I will take a look

QMap iterators are bidirectional: for(auto i = map.keyEnd()-1;i!=map.keyBegin();--i)
