Detailed Description
Use QMetaSequence::Iterable instead.
This class allows several methods of accessing the values of a container held within a QVariant. An instance of QSequentialIterable can be extracted from a QVariant if it can be converted to a QVariantList.
The container itself is not copied before iterating over it.
See also QVariant.
Member Type Documentation
[alias] QSequentialIterable::BidirectionalConstIterator
Exposes a const_iterator using std::bidirectional_iterator_tag.
[alias] QSequentialIterable::BidirectionalIterator
Exposes an iterator using std::bidirectional_iterator_tag.
[alias] QSequentialIterable::ForwardConstIterator
Exposes a const_iterator using std::forward_iterator_tag.
[alias] QSequentialIterable::ForwardIterator
Exposes an iterator using std::forward_iterator_tag.
[alias] QSequentialIterable::InputConstIterator
Exposes a const_iterator using std::input_iterator_tag.
[alias] QSequentialIterable::InputIterator
Exposes an iterator using std::input_iterator_tag.
[alias] QSequentialIterable::RandomAccessConstIterator
Exposes a const_iterator using std::random_access_iterator_tag.
[alias] QSequentialIterable::RandomAccessIterator

[alias, until 6.15] QSequentialIterable::const_iterator
This typedef is scheduled for deprecation in version 6.15.
Use QMetaSequence::Iterable::ConstIterator instead.
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.

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.
This typedef was introduced in Qt 6.0.
Member Function Documentation
void QSequentialIterable::addValue(const QVariant &value, QSequentialIterable::Position position = Unspecified)
Adds value to the container, at position, if possible.
QVariant QSequentialIterable::at(qsizetype idx) const
Returns the value at position idx in the container.
void QSequentialIterable::removeValue(QSequentialIterable::Position position = Unspecified)
Removes a value from the container, at position, if possible.
void QSequentialIterable::set(qsizetype idx, const QVariant &value)
Sets the element at position idx in the container to value.
