6.11

QMetaSequence::Iterable::ConstIterator allows iteration over a container in a QVariant.

A QMetaSequence::Iterable::ConstIterator can only be created by a QMetaSequence::Iterable instance, and can be used in a way similar to other stl-style iterators.

        QList<int> intList = {7, 11, 42};
 
        QVariant variant = QVariant::fromValue(intList);
        if (variant.canConvert<QVariantList>()) {
            QMetaSequence::Iterable iterable = variant.value<QMetaSequence::Iterable>();
            // Can use C++11 range-for:
            for (const QVariant &v : iterable) {
                qDebug() << v;
            }
            // Can use iterators:
            QMetaSequence::Iterable::const_iterator it = iterable.begin();
            const QMetaSequence::Iterable::const_iterator end = iterable.end();
            for ( ; it != end; ++it) {
                qDebug() << *it;
            }
        }
