netbeans - how to apply mousemotion listener on a single cube using JOGL -

i had created 3d cube in jogl using netbeans , want perform mouse drag event on single object using mousemotion listener interface mouse drag event occured when adding other object in canvas , rotation of cube , other object performs simultaneously want rotate cube using mouse drag event so, please suggest me solution problem thank you
