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.


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

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


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
