Detailed Description

vtkTextSourceRepresentation is a representation to show text. The input is expected to a vtkTable with a single row and column (atleast on the data server nodes). The content of this entry in the table is shown as text on the rendering nodes.

static vtkTextSourceRepresentation* vtkTextSourceRepresentation::New ( ) [static]

Reimplemented from vtkDataRepresentation.

virtual const char* vtkTextSourceRepresentation::GetClassName ( ) [virtual]

Reimplemented from vtkPVDataRepresentation.

static int vtkTextSourceRepresentation::IsTypeOf ( const char * type ) [static]

Reimplemented from vtkPVDataRepresentation.

virtual int vtkTextSourceRepresentation::IsA ( const char * type ) [virtual]

Reimplemented from vtkPVDataRepresentation.

static vtkTextSourceRepresentation* vtkTextSourceRepresentation::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkPVDataRepresentation.

void vtkTextSourceRepresentation::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Reimplemented from vtkPVDataRepresentation.

void vtkTextSourceRepresentation::SetTextWidgetRepresentation ( vtk3DWidgetRepresentation * widget )

Set the text widget.

virtual vtk3DWidgetRepresentation* vtkTextSourceRepresentation::GetTextWidgetRepresentation ( ) [virtual]

Set the text widget.

virtual void vtkTextSourceRepresentation::MarkModified ( ) [virtual]

This is one of the most important functions. In VTK pipelines, it's very easy for the pipeline to decide when it needs to re-execute. vtkAlgorithm::Update() can go up the entire pipeline to see if any filters MTime changed (among other things) and if so, it can re-execute the pipeline. However in case of representations, the real input connection may only be present on the data-server nodes. In that case the vtkPVDataRepresentation::RequestData() will only get called on the data-server nodes. That means that representations won't be able to any data-delivery in RequestData(). We'd need some other mechanisms to synchronize data-delivery among processes. To avoid that conundrum, the vtkSMRepresentationProxy calls MarkModified() on all processes whenever any filter in the pipeline is modified. In this method, the vtkPVDataRepresentation subclasses should ensure that they mark all delivery related filters dirty in their RequestData to ensure they execute then next time they are updated. The vtkPVDataRepresentation also uses a special executive which avoids updating the representation unless MarkModified() was called since the last Update(), thus acting as a update-suppressor.

Reimplemented from vtkPVDataRepresentation.

virtual void vtkTextSourceRepresentation::SetVisibility ( bool ) [virtual]

Set the visibility.

Reimplemented from vtkPVDataRepresentation.

void vtkTextSourceRepresentation::SetInteractivity ( bool )

Set the interactivity.

int vtkTextSourceRepresentation::ProcessViewRequest	(	vtkInformationRequestKey *	request_type,
		vtkInformation *	inInfo,
		vtkInformation *	outInfo
	)		`[virtual]`

vtkAlgorithm::ProcessRequest() equivalent for rendering passes. This is typically called by the vtkView to request meta-data from the representations or ask them to perform certain tasks e.g. PrepareForRendering.

Reimplemented from vtkPVDataRepresentation.

virtual int vtkTextSourceRepresentation::FillInputPortInformation	(	int	port,
		vtkInformation *	info
	)		`[protected, virtual]`

Fill input port information.

Reimplemented from vtkDataRepresentation.

virtual int vtkTextSourceRepresentation::RequestData	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)		`[protected, virtual]`

Overridden to invoke vtkCommand::UpdateDataEvent.

Reimplemented from vtkPVDataRepresentation.

virtual bool vtkTextSourceRepresentation::AddToView ( vtkView * view ) [protected, virtual]

Adds the representation to the view. This is called from vtkView::AddRepresentation(). Subclasses should override this method. Returns true if the addition succeeds.

Reimplemented from vtkPVDataRepresentation.

virtual bool vtkTextSourceRepresentation::RemoveFromView ( vtkView * view ) [protected, virtual]

Removes the representation to the view. This is called from vtkView::RemoveRepresentation(). Subclasses should override this method. Returns true if the removal succeeds.

Reimplemented from vtkPVDataRepresentation.

virtual bool vtkTextSourceRepresentation::IsCached ( double cache_key ) [protected, virtual]

Overridden to check with the vtkPVCacheKeeper to see if the key is cached.

Reimplemented from vtkPVDataRepresentation.
