DESCRIPTION

This subclass of SbPList holds lists of pointers to instances of classes derived from SoPickedPoint. It is used primarily to return information from picking with the SoRayPickAction class.

METHODS

       
                    
                     SoPickedPointList()
Constructor.

       
                    
                     SoPickedPointList(int size)
Constructor that pre-allocates storage for size pointers.

       
                    
                     SoPickedPointList(const SoPickedPointList &l)
Constructor that copies the contents of another list.

       
                    
                     ~SoPickedPointList()
Destructor.

    void    
                    
void                 append(SoPickedPoint *ptr)
Adds a pointer to the end of the list.

    void    
                    
void                 insert(SoPickedPoint *ptr, int addBefore)
Inserts given pointer in list before pointer with given index.

    void    
                    
void                 truncate(int start)
Removes all pointers after one with given index, inclusive, deleting all instances removed from the list.

    SoPickedPoint *    
                    
SoPickedPoint *      operator [](int i) const
Accesses an element of a list.

    void    
                    
void                 set(int i, SoPickedPoint *pickedPoint)
Sets an element of a list.
