modelHistoryLog->setHeaderData(0,Qt::Horizontal,codec->toUnicode("C1"));
modelHistoryLog->setHeaderData(1,Qt::Horizontal,codec->toUnicode("C2"));
modelHistoryLog->setHeaderData(2,Qt::Horizontal,codec->toUnicode("C3"));

column will display: C1 C2 C3


but

I want: C3 C1 C2

---

modelHistoryLog->setHeaderData(0,Qt::Horizontal,codec->toUnicode("C3"));
modelHistoryLog->setHeaderData(1,Qt::Horizontal,codec->toUnicode("C1"));
modelHistoryLog->setHeaderData(2,Qt::Horizontal,codec->toUnicode("C2"));
