	QIterator (QIterable< QMetaSequence > iterable, void iterator)
	Creates an iterator from an iterable and a pointer to a native iterator.

bool	operator== (const QIterator &o) const
	Returns `true` if other points to the same item as this iterator; otherwise returns `false`.

bool	operator!= (const QIterator &o) const
	Returns `true` if other points to a different item than this iterator; otherwise returns `false`.

QIterator &	operator++ ()
	The prefix {++} operator ({++it}) advances the iterator to the next item in the container and returns an iterator to the new current item.

QIterator	operator++ (int)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.The postfix {++} operator ({it++}) advances the iterator to the next item in the container and returns an iterator to the previously current item.

QIterator &	operator-- ()
	The prefix {–} operator ({–it}) makes the preceding item current and returns an iterator to the new current item.

QIterator	operator-- (int)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.The postfix {–} operator ({it–}) makes the preceding item current and returns an iterator to the previously current item.

QIterator &	operator+= (qsizetype j)
	Advances the iterator by j items.

QIterator &	operator-= (qsizetype j)
	Makes the iterator go back by j items.

QIterator	operator+ (qsizetype j) const
	Returns an iterator to the item at j positions forward from this iterator.

QIterator	operator- (qsizetype j) const
	Returns an iterator to the item at j positions backward from this iterator.

qsizetype	operator- (const QIterator &j) const
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.Returns the distance between the two iterators.

\typealias QSequentialIterable::const_iterator

The QSequentialIterable::const_iterator allows iteration over a container in a QVariant.

A QSequentialIterable::const_iterator can only be created by a QSequentialIterable 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>()) {
    QSequentialIterable iterable = variant.value<QSequentialIterable>();
    // Can use foreach:
    foreach (const QVariant &v, iterable) {
        qDebug() << v;
    }
    // Can use C++11 range-for:
    for (const QVariant &v : iterable) {
        qDebug() << v;
    }
    // Can use iterators:
    QSequentialIterable::const_iterator it = iterable.begin();
    const QSequentialIterable::const_iterator end = iterable.end();
    for ( ; it != end; ++it) {
        qDebug() << *it;
    }
}
 

\typealias QSequentialIterable::iterator

Since: 6.0

The QSequentialIterable::iterator allows iteration over a container in a QVariant.

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

Returns the current item, converted to a QVariantRef.

◆ operator->()

QVariantPointer< QSequentialIterator > QSequentialIterator::operator-> ( ) const

Returns the current item, converted to a QVariantPointer.
