Qstring To Qbytearray, QString::localeAwareCompare () is a better choice for sorting user-interface strings.

Qstring To Qbytearray, A null byte I have a QString which contains some unicode chars, and I want to convert the QString to a QByteArray. This makes it possible to access the byte array using QDataStream and QTextStream. Both QByteArray and std::string have constructors for raw data (C-string + length) and also a Hello Qt users. 2k Views Oldest to Newest Converting QString to QByteArray using toUtf8 () resulting in QByteArray with extra characters Unsolved General and Desktop 6 Posts 5 Posters 3.
