Qt QString: Primera letra mayúscula

[Madh]

Código C++:

QString Utils::ucfirst(const QString str) {
    if (str.size() < 1) {
        return "";
    }
 
    QStringList tokens = str.split(" ");
    QList<QString>::iterator tokItr = tokens.begin();
 
    for (tokItr = tokens.begin(); tokItr != tokens.end(); ++tokItr) {
        (*tokItr) = (*tokItr).at(0).toUpper() + (*tokItr).mid(1);
    }
 
    return tokens.join(" ");
}
