Detailed Description

JsonTreeModelNamedListNode represents a JSON object.

Scalar members of this node appear in named scalar columns in the JsonTreeModel.

Non-scalar members of this node (arrays and objects) appear as child rows in the JsonTreeModel.

If this node represents a top-level object of a JSON document and it contains scalar members, then this node must be wrapped in a JsonTreeModelWrapperNode.

Constructor & Destructor Documentation

JsonTreeModelNamedListNode()

JsonTreeModelNamedListNode::JsonTreeModelNamedListNode	(	const QJsonObject &	object,
		JsonTreeModelNode *	parent
	)

Constructs a node under the specified parent to represent the specified JSON object.

Member Function Documentation

childListNodeName()

QString JsonTreeModelNamedListNode::childListNodeName ( JsonTreeModelNode *  child ) const

inline

namedScalarCount()

int JsonTreeModelNamedListNode::namedScalarCount ( ) const

inline

Returns the number of scalar elements within this node.

In the JsonTreeModel, these are the elements that appear under the model's scalar columns.

namedScalarValue()

QJsonValue JsonTreeModelNamedListNode::namedScalarValue ( const QString &  name ) const

inline

Returns the scalar element in this node which has the given name.

If the underlying JSON object has no member with the given name (or if the member is non-scalar), this function returns an undefined QJsonValue.

setNamedScalarValue()

setNamedScalarValue()

void JsonTreeModelNamedListNode::setNamedScalarValue ( const QString &  name, const QJsonValue &  value  )

inline

Adds or updates a scalar element of the JSON object represented by this node.

namedScalarValue()

type()

Type JsonTreeModelNamedListNode::type ( ) const

inlineoverridevirtual

Returns JsonTreeModelNode::Object.

Reimplemented from JsonTreeModelListNode.

value()

QJsonValue JsonTreeModelNamedListNode::value ( ) const

overridevirtual

Returns the JSON object represented by this node.

Reimplemented from JsonTreeModelListNode.
