  \class SoInteraction SoInteraction.h Inventor/SoInteraction.h
  \brief The SoInteraction class takes care of initalizing internal classes.
  \ingroup general

  SoInteraction is present for the sole purpose of providing an
  interface to the initialization methods of the classes in Coin which
  are somehow related to user interaction, like the draggers and
  manipulators.

  It is unlikely that the application programmer should need to worry
  about this class, as SoInteraction::init() is called by the GUI
  specific initialization methods.

  Calls the initClass() method of these classes: SoAntiSquish,
  SoSelection, SoExtSelection, SoSurroundScale, SoInteractionKit,
  SoDragger, SoClipPlaneManip, SoDirectionalLightManip,
  SoPointLightManip, SoSpotLightManip, SoTransformManip,
  SoCenterballManip, SoHandleBoxManip, SoJackManip, SoTabBoxManip,
  SoTrackballManip, SoTransformBoxManip, SoTransformerManip.

  Note that this method calls SoDB::init() and SoNodeKit::init() to
  make sure all classes that the interaction functionality depends on
  have been initialized.


  Application programmers should usually not have to invoke this method
  directly from application code, as it is indirectly called from the
  GUI-binding libraries' init()-functions.  Only if you are using your own
  GUI-binding (and not one of Kongsberg Oil & Gas Technologies's SoQt, SoGtk,
  SoXt, SoWin, Sc21 etc. libraries) do you have to explicitly call
  SoInteraction::init().

  \code
  int main(int argc, char ** argv )
  {
    // SoQt::init() calls SoDB::init(), SoNodeKit::init() and
    // SoInteraction::init().
    QWidget * window = SoQt::init( argv[0] );

    SoSeparator * root = make_scenegraph();
    root->ref();
    /// [... etc ...] ///
