glutSpaceballMotionFunc(3GLUT)                      GLUT                      glutSpaceballMotionFunc(3GLUT)



NAME
       glutSpaceballMotionFunc - sets the Spaceball motion callback for the current window.

SYNTAX
       #include <GLUT/glut.h>

       void glutSpaceballMotionFunc(void (*func)(int x, int y, int z));

ARGUMENTS
       func      The new entry callback function.

DESCRIPTION
       glutSpaceballMotionFunc  sets  the  Spaceball  motion  callback for the current window. The Spaceball
       motion callback for a window is called when the window has Spaceball input focus (normally, when  the
       mouse  is  in  the  window)  and the user generates Spaceball translations.  The x, y, and z callback
       parameters indicate the translations along the X, Y, and Z axes. The callback parameters are  normal-ized normalized
       ized to be within the range of -1000 to 1000 inclusive.

       Registering a Spaceball motion callback when a Spaceball device is not available has no effect and is
       not an error. In this case, no Spaceball motion callbacks will be generated.

       Passing NULL to glutSpaceballMotionFunc disables the generation of Spaceball motion callbacks. When a
       new window is created, no Spaceball motion callback is initially registered.
