Constructor & Destructor Documentation

§ pqSILModel()

pqSILModel::pqSILModel ( QObject * parent = 0 )

§ ~pqSILModel()

virtual pqSILModel::~pqSILModel ( )

virtual

Member Function Documentation

§ rowCount()

virtual int pqSILModel::rowCount ( const QModelIndex & parent = QModelIndex() ) const

virtual

Gets the number of rows for a given index.

Parameters

parent The parent index.

Returns: The number of rows for the given index.

§ columnCount()

virtual int pqSILModel::columnCount ( const QModelIndex & parent = QModelIndex() ) const

virtual

Gets the number of columns for a given index.

Parameters

parent The parent index.

Returns: The number of columns for the given index.

§ hasChildren()

virtual bool pqSILModel::hasChildren ( const QModelIndex & parent = QModelIndex() ) const

virtual

Gets whether or not the given index has child items.

Parameters

parent The parent index.

Returns: True if the given index has child items.

§ index()

virtual QModelIndex pqSILModel::index	(	int	row,
		int	column,
		const QModelIndex &	parent = `QModelIndex()`
	)		const

virtual

Gets a model index for a given location.

Parameters

row	The row number.
column	The column number.
parent	The parent index.

Returns: A model index for the given location.

§ parent() [1/2]

virtual QModelIndex pqSILModel::parent ( const QModelIndex & index ) const

virtual

Gets the parent for a given index.

Parameters

index The model index.

Returns: A model index for the parent of the given index.

§ data()

virtual QVariant pqSILModel::data	(	const QModelIndex &	index,
		int	role = `Qt::DisplayRole`
	)		const

virtual

Gets the data for a given model index.

Parameters

index	The model index.
role	The role to get data for.

Returns: The data for the given model index.

§ flags()

virtual Qt::ItemFlags pqSILModel::flags ( const QModelIndex & index ) const

virtual

Gets the flags for a given model index.

The flags for an item indicate if it is enabled, editable, etc.

Parameters

index The model index.

Returns: The flags for the given model index.

§ setData()

bool pqSILModel::setData	(	const QModelIndex &	index,
		const QVariant &	value,
		int	role = `Qt::EditRole`
	)

Sets the role data for the item at index to value.

Returns true if successful; otherwise returns false.

§ hierarchyIndex()

QModelIndex pqSILModel::hierarchyIndex ( const QString & hierarchyName ) const

Returns the QModelIndex for the hierarchy with the given name, if present.

If the hierarchy is not present an index referring to an empty tree will be returned.

§ headerData()

virtual QVariant pqSILModel::headerData	(	int	,
		Qt::Orientation	,
		int	role = `Qt::DisplayRole`
	)		const

inlinevirtual

Definition at line 144 of file pqSILModel.h.

§ status()

QList<QVariant> pqSILModel::status ( const QString & hierarchyName ) const

API to get/set status of a given hierarchy.

§ setStatus()

void pqSILModel::setStatus	(	const QString &	hierarchyName,
		const QList< QVariant > &	values
	)

§ makeIndex()

QModelIndex pqSILModel::makeIndex ( vtkIdType vertexid ) const

Returns the model index for a vertex.

§ findVertex()

vtkIdType pqSILModel::findVertex ( const char * name ) const

Returns the vertex id for a vertex with the given name in the SIL.

Returns -1 if no such vertex could be found.

§ checkStatusChanged

void pqSILModel::checkStatusChanged ( )

signal

§ update

void pqSILModel::update ( vtkGraph * sil )

slot

Used to reset the model based on the sil.

§ checkStateUpdated()

void pqSILModel::checkStateUpdated	(	vtkObject *	caller,
		unsigned long	eventid,
		void *	calldata
	)

protected

Called every time vtkSMSILModel tells us that the check state has changed.

We fire the dataChanged() event so that the view updates.

§ isLeaf()

bool pqSILModel::isLeaf ( vtkIdType vertexid ) const

protected

Returns if the given vertex id refers to a leaf node.

§ parent() [2/2]

vtkIdType pqSILModel::parent ( vtkIdType vertexid ) const

protected

Returns the parent vertex id for the given vertex.

It's an error to call this method for the root vertex id i.e. 0.

§ childrenCount()

int pqSILModel::childrenCount ( vtkIdType vertexid ) const

protected

Returns the number of children for the given vertex.

§ collectLeaves()

void pqSILModel::collectLeaves	(	vtkIdType	vertexid,
		std::set< vtkIdType > &	list
	)

protected

Used to initialize the HierarchyVertexIds list with the leaf node ids for each of the hierarchies.
