Detailed Description

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;
     }
 }
