SoXtSpaceball — translates and reports events for the spaceball

       This  class  manages  events generated by the spaceball, including spaceball motion (SoMotion3Event), and
       spaceball button press and release events (SoSpaceballButtonEvent).

SoXtSpaceball(SoXtSpaceball::Maskmask=SoXtSpaceball::ALL)SoXtSpaceball(Display*d,SoXtSpaceball::Maskmask=SoXtSpaceball::ALL)~SoXtSpaceball()
          Constructor and destructor. Pass to the constructor an enumerated  value  specifying  which  spaceball
          events  are of interest. Only those events will be reported to the callback routine registered on each
          widget.  The first constructor uses the X display which was set in SoXt::init().

     voidsetRotationScaleFactor(floatf)floatgetRotationScaleFactor()const
          Set and get the rotation scale factor. The scale factor is applied to the rotation value generated  by
          the spaceball device. The default rotation scale factor is .006.

     voidsetTranslationScaleFactor(floatf)floatgetTranslationScaleFactor()const
          Set  and  get  the  translation  scale  factor.  The  scale factor is applied to the translation value
          generated by the spaceball device. The default translation scale factor is .006.

          This returns TRUE if the spaceball exists, either on the X display which was set in SoXt::init(),   or
          on the passed display.
