                                    SbViewportRegion *newRegion)
     const SbViewportRegion *  SoPickActGetVPReg(const SoPickAct *this)

          Functions from class SoAction:

     SoType              SoPickActGetTypeId(SoPickAct *this)
     SbBool              SoPickActIsOfType(SoPickAct *this, SoType type)
     void                SoPickActInvalidateState(SoPickAct *this)


DESCRIPTION
     This is an abstract base class for all picking actions. Currently, the
     only supported subclass is the SoRayPickAction.

FUNCTIONS
     void                      SoPickActSetVPReg(SoPickAct *this, const
                                    SbViewportRegion *newRegion)
     const SbViewportRegion *  SoPickActGetVPReg(const SoPickAct *this)
          Sets/returns current viewport region to use for action. Even though
          the picking operation may not involve a window per se, some nodes
          need this information to determine their size and placement.
