 |   $Revision: 1.1.1.1 $
 |
 |   Description:
 |	This file defines the transform box dragger class.
 |	This dragger allows you to perform rotations,uniform scales
 |	and translations, all in one tidy box.
 |
 | NOTE TO DEVELOPERS:
 |     For info about the structure of SoTabBoxDragger:
 |     [1] compile: /usr/share/src/Inventor/samples/ivNodeKitStructure
 |     [2] type:    ivNodeKitStructure SoTabBoxDragger.
 |     [3] The program prints a diagram of the scene graph and a table with 
 |         information about each part.
 |
 |  The following parts in this dragger are created at construction time.
 |  'ResourceName' corresponds to the name of the default geometry for the
 |  part. The dragger's constructor gets the scene graph for 'ResourceName'
 |  by querying the global dictionary ( SoDB::getByName("ResourceName"); ).  
 |
 |  Resource Name:                           Part Name:
 |
 |  tabBoxBoxGeom                          - boxGeom
 |
 |  tabBoxTranslator                       - tabPlane1.translator
 |  tabBoxScaleTabMaterial                 - tabPlane1.scaleTabMaterial
 |  tabBoxScaleTabHints                    - tabPlane1.scaleTabHints
 |  (ditto for tabPlane2 - tabPlane6)
