   Classes
       class SoExtSelection
           The SoExtSelection class can be used for extended selection functionality.

       This class enables you to select geometry by specifying a lasso (a polygon) or a rectangle
       on screen. When objects are selected, you'll receive the same callbacks as for the
       SoSelection node. "
