DESCRIPTION

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

METHODS

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