Member Function Documentation

◆ AdditionalInitializeStep()

void vtkMRMLColorLegendDisplayableManager::AdditionalInitializeStep ( )

Method to perform additional initialization.

Reimplemented from vtkMRMLAbstractDisplayableManager.

◆ Create()

void vtkMRMLColorLegendDisplayableManager::Create ( )

Initialize the displayable manager based on its associated vtkMRMLSliceNode

Reimplemented from vtkMRMLAbstractDisplayableManager.

◆ GetClassName()

virtual const char* vtkMRMLColorLegendDisplayableManager::GetClassName ( )

Reimplemented from vtkMRMLAbstractDisplayableManager.

◆ GetColorLegendActor()

vtkSlicerScalarBarActor* vtkMRMLColorLegendDisplayableManager::GetColorLegendActor ( vtkMRMLColorLegendDisplayNode dispNode) const

Get scalar bar actor.

dispNode- color legend display node
scalar bar actor pointer

◆ IsA()

virtual int vtkMRMLColorLegendDisplayableManager::IsA ( const char *  type)

Reimplemented from vtkMRMLAbstractDisplayableManager.

◆ IsTypeOf()

static int vtkMRMLColorLegendDisplayableManager::IsTypeOf ( const char *  type)

◆ New()

static vtkMRMLColorLegendDisplayableManager* vtkMRMLColorLegendDisplayableManager::New ( )

◆ OnMRMLDisplayableNodeModifiedEvent()

void vtkMRMLColorLegendDisplayableManager::OnMRMLDisplayableNodeModifiedEvent ( vtkObject *  caller)

Called when the SliceNode or Three3DViewNode are modified. May cause ColorLegend to remap its position on screen.

Reimplemented from vtkMRMLAbstractDisplayableManager.

◆ OnMRMLSceneNodeAdded()

void vtkMRMLColorLegendDisplayableManager::OnMRMLSceneNodeAdded ( vtkMRMLNode )

If vtkMRMLScene::NodeAddedEvent has been set to be observed in SetMRMLSceneInternal, it is called when the scene fires the event

See also
ProcessMRMLSceneEvents, SetMRMLSceneInternal
OnMRMLSceneNodeRemoved, vtkMRMLScene::NodeAboutToBeAdded

Reimplemented from vtkMRMLAbstractLogic.

◆ OnMRMLSceneNodeRemoved()

void vtkMRMLColorLegendDisplayableManager::OnMRMLSceneNodeRemoved ( vtkMRMLNode )

If vtkMRMLScene::NodeRemovedEvent has been set to be observed in SetMRMLSceneInternal, it is called when the scene fires the event

See also
ProcessMRMLSceneEvents, SetMRMLSceneInternal
OnMRMLSceneNodeAdded, vtkMRMLScene::NodeAboutToBeRemoved

Reimplemented from vtkMRMLAbstractLogic.

◆ PrintSelf()

void vtkMRMLColorLegendDisplayableManager::PrintSelf ( ostream &  os,
vtkIndent  indent 

◆ ProcessMRMLNodesEvents()

void vtkMRMLColorLegendDisplayableManager::ProcessMRMLNodesEvents ( vtkObject *  caller,
unsigned long  event,
void *  callData 

Receives all the events fired by the nodes. To listen to a node, you can add an observer using GetMRMLNodesCallbackCommand() or use the utility macros vtk[SetAndObserve|Observe]MRMLNode[Event]Macro ProcessMRMLNodesEvents calls OnMRMLNodeModified when event is vtkCommand::ModifiedEvent.

◆ SetMRMLSceneInternal()

void vtkMRMLColorLegendDisplayableManager::SetMRMLSceneInternal ( vtkMRMLScene newScene)

Called by SetMRMLScene - Used to initialize the Scene Observe all the events of the scene and call OnMRMLSceneEndClose() or OnMRMLSceneEndImport() if the new scene is valid

Reimplemented from vtkMRMLAbstractDisplayableManager.

◆ UnobserveMRMLScene()

void vtkMRMLColorLegendDisplayableManager::UnobserveMRMLScene ( )

Called anytime a scene is not set to the logic anymore (e.g. a new or no scene is set) Reimplement the method to delete all the scene specific information such as a node IDs, pointers...

See also
SetMRMLSceneInternal, ObserveMRMLScene, UpdateFromMRMLScene

Reimplemented from vtkMRMLAbstractLogic.

◆ UpdateFromMRML()

void vtkMRMLColorLegendDisplayableManager::UpdateFromMRML ( )

Called from RequestRender method if UpdateFromMRMLRequested is true

See also
RequestRender() SetUpdateFromMRMLRequested()

Reimplemented from vtkMRMLAbstractDisplayableManager.

◆ UpdateFromMRMLScene()

void vtkMRMLColorLegendDisplayableManager::UpdateFromMRMLScene ( )

Called every time the scene has been significantly changed. If the scene BatchProcessState events are observed (in SetMRMLSceneInternal() ), UpdateFromMRMLScene is called after each batch process (Close, Import, Restore...). It is also being called by default when a new scene is set (SetMRMLScene).
