◆ vtkSetAndObserveMRMLNodeMacro

#define vtkSetAndObserveMRMLNodeMacro (   node,
  value 
)
Value:

#define vtkObjectPointer(xx)

Set and observe a MRML node. Replace the existing value of node with value. Unobserve the old node and observe the ModifiedEvent of the new. When the new node is modified, vtkMRMLAbstractLogic::ProcessMRMLNodesEvents is called which propagate the call to vtkMRMLAbstractLogic::OnMRMLNodeModified(vtkMRMLNode*) automatically.

Can't be used with objects other than vtkMRMLNodes
