vtkMRMLAbstractDisplayableManager * FocusedDisplayableManager
Superclass for displayable manager classes.
vtkWeakPointer< vtkMRMLDisplayableManagerGroup > DisplayableManagers
vtkSmartPointer< vtkTimerLog > ClickTimer
Measures time elapsed since first button press.
Common base class for processing interaction events in MRML views.
DisplayableManagerGroup is a collection of DisplayableManager.
