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. "
