如何使用分隔符“-”将QByteArray转换为QString？

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;
