How can I convert QByteArray to QString with separator '-'?

Question

I'm new in Qt and can't find any solution in Qt libraries.
I'd like to find smth without loop usage.
Is there any way to convert QByteArray to QString with - between bytes?
For example:

QByteArray = XX1F2C5A
QString = "XX-1F-2C-5A".

Answer 1

Yeah you can with QString::replace :

  QByteArray b = "XX1F2C5A";
  QString s(b);
  qDebug() << s;
  s.replace(QRegExp("(..)[^$]"), QString("\\1-"));
  qDebug() << s;
