QSet<QVariant> is supported ?

[nikhilqt]

QList<QVariant> list;
QSet<QVariant> varSet;
varSet = list.toSet();

QList<QVariant> list;
QSet<QVariant> varSet;
varSet = list.toSet();

To copy to clipboard, switch view to plain text mode 

Is this not possible? Am getting error If i do so saying this overload is not supported.

QSet is based on QHash. QHash doesn't know how to hash a QVariant. You'll have to find a different solution for what you want, or if the variants are all of the same type, convert them to the type and make a set out of that.

Aside from that you could tell QHash how to hash a QVariant, by providing a qHash() function for QVariants.
