public SoNode GetTriggerNode()

Public Function GetTriggerNode As SoNode

public:
SoNode^ GetTriggerNode()

member GetTriggerNode : unit -> SoNode 

Return Value

Returns NULL if the sensor was not triggered because a node changed (for example, if () is called on the sensor) or if this sensor is not a priority 0 sensor. Note that because one change to the scene graph may cause multiple nodes or fields to be modified (because of field-to-field connections), the node returned may not be the only one that changed.
