     const SbViewportRegion &  getViewportRegion() const

          Methods from class SoAction:

     virtual void        apply(SoNode *node)
     virtual void        apply(SoPath *path)
     virtual void        apply(const SoPathList &pathList, SbBool obeysRules = FALSE)

DESCRIPTION

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

METHODS

     void                      setViewportRegion(const SbViewportRegion &newRegion)
     const SbViewportRegion &  getViewportRegion() const
          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.
