Run the picking selection process and return true if the object is associated with the given picker i...
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void RemovePicker(vtkAbstractPicker *picker, vtkObject *object=nullptr)
Unregister the picker from the picking manager.
bool Pick(vtkObject *object)
