Saving 64-bit integer with QSettings

Question

Is there any neat way, short of converting number to QByteArray, to save quint64 with QSettings? The problem is QVariant doesn't accept qint64 nor quint64.

Answer 1

QVariant supports qlonglong and qulonglong. As the documentation says, these are the same as qint64 and quint64. So you can just use QVariant::QVariant(qlonglong) and QVariant::toLongLong.
