Collaboration diagram for vtkMRMLLayerDMSelectionObserver:

Helper class to observe changes to the interaction / selection singleton pairs. When either selection or interaction change, triggers a modified event.

Provides helper methods to check if a given node is currently in place mode.

Unnamed Group

void SetScene(vtkMRMLScene *scene)

Updates selection and interaction nodes from the input scene Uses the singleton instances defined in the scene. For finer granularity, use the direct setters.

void UpdateNodesFromScene(vtkMRMLScene *scene)

Public Functions

vtkTypeMacro(vtkMRMLLayerDMSelectionObserver, vtkObject)

void UpdateNodesFromApplicationLogic(vtkMRMLApplicationLogic *logic)

Updates selection and interaction nodes from the input application logic Doesn’t store the application logic instance.

bool SetInteractionNode(vtkMRMLInteractionNode *interactionNode)

vtkMRMLInteractionNode *GetInteractionNode() const

bool SetSelectionNode(vtkMRMLSelectionNode *selectionNode)

vtkMRMLSelectionNode *GetSelectionNode() const

bool IsPlacing(vtkMRMLNode *node) const

Returns:

true if the interaction is in place mode and selection active node is the input mrml node

bool IsPlacing() const

Returns:

true if the interaction is in place mode

void StartPlace(vtkMRMLNode *node, bool isPersistent)

Starts placing the input node (selection to node ID + interaction in place mode)

void StopPlace() const

Sets the interaction mode to view.

std::string GetActivePlaceNodeID() const

void SetInteractionMode(int interactionMode) const

int GetCurrentInteractionMode() const

bool GetPlaceModePersistence() const

Returns:

true if currently placing and in persistent mode.
