pqSILModel::pqSILModel ( QObject * parent = 0 )

virtual pqSILModel::~pqSILModel ( ) [virtual]

Member Function Documentation

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

Definition at line 126 of file pqSILModel.h.

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

API to get/set status of a given hierarchy.

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

QModelIndex pqSILModel::makeIndex ( vtkIdType vertexid ) const

Returns the model index for a vertex.

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.

void pqSILModel::checkStatusChanged ( ) [signal]

void pqSILModel::update ( vtkGraph * sil ) [slot]

Used to reset the model based on the sil.

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.

bool pqSILModel::isLeaf ( vtkIdType vertexid ) const [protected]

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

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.

int pqSILModel::childrenCount ( vtkIdType vertexid ) const [protected]

Returns the number of children for the given vertex.

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.
