  \brief The SoTransformer2Manip wraps an SoTransformer2Dragger for convenience.
  \ingroup manips

  ![](http://doc.coin3d.org/images/Coin/draggers/transformer.png)

  The manipulator class takes care of wrapping up the
  SoTransformer2Dragger in a simple and convenient API for the
  application programmer, making it automatically surround the
  geometry it influences and taking care of the book-keeping routines
  for it's interaction with the relevant fields of an SoTransformation
  node.
