public class QXmlNodeModelIndex
The QXmlNodeModelIndex class identifies a node in an XML node model subclassed from QAbstractXmlNodeModel
. QXmlNodeModelIndex is an index into an XML node model
. It contains:
XML node model
, which is returned by model()
, anddata()
, internalPointer(), and additionalData()
.XML receiver
, orQXmlQuery::evaluateTo()
that populates a QStringList, which you can send directly to your widget. QXmlNodeModelIndex doesn't impose any restrictions on the data value an QXmlNodeModelIndex should contain. The meaning of the data left to the associated node model
. Because QXmlNodeModelIndex depends on a particular subclass of QAbstractXmlNodeModel
for its existence, the only way you can create an instance of QXmlNodeModelIndex is by asking the node model to create one for you with QAbstractXmlNodeModel::createIndex()
. Since that function is protected, it is usually a good ide to write a public function that creates a QXmlNodeModelIndex from arguments that are appropriate for your particular node model.
A default constructed node index is said to be null, i.e., isNull()
returns true.
QXmlNodeModelIndex and QAbstractXmlNodeModel
follow the same design pattern used for QModelIndex and QAbstractItemModel
.

A null QXmlNodeModelIndex doesn't represent any node and cannot be used in conjunction with QAbstractXmlNodeModel
.
public final QAbstractXmlNodeModel model()
QAbstractXmlNodeModel
that this node index refers to. QXmlNodeModelIndex does not own QAbstractXmlNodeModel
and does not keep track of its lifetime, so this pointer will dangle if the QAbstractXmlNodeModel
is deallocated first. There is no setter for the node model because instances of QXmlNodeModelIndex instances are only created with QAbstractXmlNodeModel::createIndex()
.
