DESCRIPTION

33       This  is an abstract base class for all picking actions. Currently, the
34       only supported subclass is the SoRayPickAction.
35

METHODS

37     void                      setViewportRegion(const        SbViewportRegion
38                                    &newRegion)
39     const SbViewportRegion &  getViewportRegion() const
40          Sets/returns  current viewport region to use for action. Even though
41          the picking operation may not involve a window per  se,  some  nodes
42          need this information to determine their size and placement.
