qSort a QList<struct> by QTime

[sonichy]

Scene: a line of lyric contains more than one time tag.

struct Lyric{
        QTime time;
        QString sentence;
};
QList<Lyric> lyrics;
......
lyrics.clear();
QStringList line = slyric.split("\n");
for(int i=0; i<line.size(); i++){
    if(line.at(i).contains("]")){
        QStringList SL = line.at(i).split("]");
        for(int j=0; j<SL.length()-1; j++){
            Lyric lyric;
            QString stime = SL.at(j).mid(1);
            if((stime.length() - stime.indexOf(".")) == 3) stime += "0";
            lyric.time = QTime::fromString(stime, "mm:ss.zzz");
            lyric.sentence = SL.at(SL.length()-1);
            lyrics.append(lyric);
        }
    }
}
for(int i=0; i<lyrics.size(); i++){
    textBrowser->insertPlainText(lyrics.at(i).time.toString("mm:ss.zzz") + " " + lyrics.at(i).sentence + "\n");
}

I need something like:

qSort(lyrics.begin(), lyrics.end(), Lyric.time);

@sonichy said in qSort a QList<struct> by QTime:

qSort

U mean this http://doc.qt.io/archives/qt-4.8/qtalgorithms.html#qSort-2 ?

you can use std::sort and define your own function /lambda to sort by.

something like this (untested)

QList<Lyric> lyrics;
std::sort(lyrics.begin(), lyrics.end(), [](const Lyric& a, const Lyric& b)->bool{return a.time < b.time;});

@J.Hilk You are really something!
