DESCRIPTION

       SoButtonEvent  represents  generic button press and release events in the Inventor event model. It is the
       base  class  for  device-specific  button  events,  namely   SoKeyboardEvent,   SoMouseButtonEvent,   and
       SoSpaceballButtonEvent. This class stores the down/up state of the button when the event occurred.

METHODS

                           SoButtonEvent()
          Constructor.

     static SoType         getClassTypeId()
          Return the type id for the SoButtonEvent class.

     void                  setState(SoButtonEvent::State s)
     SoButtonEvent::State  getState() const
          Set and get the state of the button.
