Constructor & Destructor Documentation

pqSpreadSheetViewModel()

pqSpreadSheetViewModel::pqSpreadSheetViewModel	(	vtkSMProxy *	viewProxy,
		QObject *	parent = nullptr
	)

~pqSpreadSheetViewModel()

pqSpreadSheetViewModel::~pqSpreadSheetViewModel ( )

override

Member Function Documentation

rowCount()

int pqSpreadSheetViewModel::rowCount ( const QModelIndex &  parent = QModelIndex() ) const

override

Returns the number of rows.

columnCount()

int pqSpreadSheetViewModel::columnCount ( const QModelIndex &  parent = QModelIndex() ) const

override

Returns the number of columns.

data()

QVariant pqSpreadSheetViewModel::data ( const QModelIndex &  index, int  role = Qt::DisplayRole  ) const

override

Returns the data storeed under the given role for the item referred by the index.

headerData()

QVariant pqSpreadSheetViewModel::headerData ( int  section, Qt::Orientation  orientation, int  role = Qt::DisplayRole  ) const

override

Returns the data for the given role and section in the header with the specified orientation.

When orientation is Qt::Horizontal, pqSpreadSheetViewModel adds support for two new roles: pqSpreadSheetViewModel::SectionVisible, and pqSpreadSheetViewModel::SectionInternal. SectionVisible can be used to determine if the column (or horizontal section) is visible or hidden. SectionInternal is used to determine if the section is internal. An internal section is also hidden. When data associated with these two roles changes, the model will fire headerDataChanged signal.

sortSection()

void pqSpreadSheetViewModel::sortSection	(	int	section,
		Qt::SortOrder	order
	)

Make a server request to sort based on a given column with a given order.

isSortable()

bool pqSpreadSheetViewModel::isSortable

(

int

section

)

Return true only if the given column is sortable.

getFieldType()

int pqSpreadSheetViewModel::getFieldType

(

)

const

Returns the field type for the data currently shown by this model.

getVTKIndices()

QSet<vtkIndex> pqSpreadSheetViewModel::getVTKIndices

(

const QModelIndexList &

indexes

)

setDecimalPrecision()

void pqSpreadSheetViewModel::setDecimalPrecision

(

int

)

Set/Get the decimal precision for float and double type data.

getDecimalPrecision()

int pqSpreadSheetViewModel::getDecimalPrecision

(

)

setFixedRepresentation()

void pqSpreadSheetViewModel::setFixedRepresentation

(

bool

)

Set/Get whether the decimal representation is fixed or scientific.

True is fixed and False is scientific

getFixedRepresentation()

bool pqSpreadSheetViewModel::getFixedRepresentation

(

)

setActiveRegion()

void pqSpreadSheetViewModel::setActiveRegion	(	int	row_top,
		int	row_bottom
	)

set the region (in row indices) that is currently being shown in the view.

the model will provide data-values only for the active-region. For any other region it will simply return a "..." text for display (in QAbstractTableModel::data(..) callback).

activeRepresentation()

pqDataRepresentation* pqSpreadSheetViewModel::activeRepresentation

(

)

const

Returns the active representation.

Active representation is the representation being shown by the view.

activeRepresentationProxy()

vtkSMProxy* pqSpreadSheetViewModel::activeRepresentationProxy

(

)

const

flags()

Qt::ItemFlags pqSpreadSheetViewModel::flags ( const QModelIndex &  index ) const

override

Method needed for copy/past cell editor.

setData()

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

override

GetRowsAsString()

QString pqSpreadSheetViewModel::GetRowsAsString

(

)

const

Returns the current rows as a CSV-formatted string, including header with column names.

Uses the vtkCSVExporter.

forceUpdate

void pqSpreadSheetViewModel::forceUpdate ( )

slot

resets the model.

setActiveRepresentation

void pqSpreadSheetViewModel::setActiveRepresentation ( pqDataRepresentation *  )

slot

Sets the active representation.

Active representation is the representation being shown by the view.

setActiveRepresentationProxy

void pqSpreadSheetViewModel::setActiveRepresentationProxy ( vtkSMProxy *  )

slot

Sets the active representation.

When using this API instead of setActiveRepresentation(pqDataRepresentation*), some functionality won't be available.

selectionChanged

void pqSpreadSheetViewModel::selectionChanged ( const QItemSelection &  selection )

signal

Fired whenever the server side selection changes.

isDataValid()

bool pqSpreadSheetViewModel::isDataValid ( const QModelIndex &  idx ) const

protected

Given an index into the model, check to see that its row number is less than the length of the data array associated with its column.

GetView()

vtkSpreadSheetView* pqSpreadSheetViewModel::GetView ( ) const

protected
