QDebug seem to not find overload ? - QMap

[Dariusz]

Hey

So I have this function :

struct myTestColor {
    double h, s, v;
    inline QColor toColor() {
        QColor c;
        c.setHsv(h, s, v);
        return c;
    }
};

inline QDebug &operator<<(QDebug &deb, QMap<QString, myTestColor> &style) {
    deb << "\n\tSize : " << style.size();
    deb << "\n\tKeys : " << style.keys();
    int x = 0;
    for (auto &key:style.keys()) {
        deb << "\n\t" << ++x << " (" << key << " : " << style[key].toColor() << "),";
    }
    return deb;
}

inline QDebug &operator<<(QDebug &deb, QMap<QString, QMap<QString, myTestColor>> &style) {
    deb << "\nSize : " << style.size();
    deb << "\nKeys : " << style.keys();
    int x = 0;
    for (auto &key:style.keys()) {
        deb << "\n" << ++x << " (" << key << " : " << style[key] << "\n),";
    }
    return deb;
}

inline QDebug &operator<<(QDebug &deb, myTestColor &style) {
    deb << style.toColor();
    return deb;
}

and this container:

QMap<QString,QMap<QString,myTestColor>> mList;

if I do

qDebug()<<mList;

without having the 2 specific QMap qDebug overloads I get an debug error cant find matching bla bla bla... Its as if QMap debug could not find inline QDebug &operator<<(QDebug &deb, myTestColor &style) in first place and needed exact debug...

This looks very strange to me and I never had that before... I think, its super weird! What did I do wrong here?

@Dariusz
your signature of the overload isn't correct: see this
also make sure those implementations are in the corresponding header file
