DESCRIPTION

       The SoBlinker class is derived from SoSwitch,  so  it  selects  one  of  its  children  to
       traverse.  Using  engines  connected to the realTime global field, the whichChild field is
       animated  over  time.  If  the  node  has  only  one  child,  whichChild  toggles  between
       SO_SWITCH_NONE  and 0, causing the child to be switched on and off repeatedly. If the node
       has more than one child, they are cycled through continuously.

FIELDS

     SoSFFloat           speed
          Defines the speed of the blinker, in cycles per second.

     SoSFBool            on
          Allows applications to enable or disable the blinking easily.

METHODS

                         SoBlinker()
          Creates a blinker node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.

ACTION BEHAVIOR

       SoGLRenderAction,     SoCallbackAction,     SoGetBoundingBoxAction,     SoGetMatrixAction,
       SoHandleEventAction, SoRayPickAction, SoSearchAction
          Same as for SoSwitch.
