glutSpaceballRotateFunc(3GLUT)                      GLUT                      glutSpaceballRotateFunc(3GLUT)



NAME
       glutSpaceballRotateFunc - sets the Spaceball rotation callback for the current window.

SYNTAX
       void glutSpaceballRotateFunc(void (*func)(int x, int y, int z));

ARGUMENTS
       func      The new spaceball rotate callback function.

DESCRIPTION
       glutSpaceballRotateFunc  sets  the  Spaceball  rotate  callback for the current window. The Spaceball
       rotate 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 rotations. The x, y, and z callback parame-ters parameters
       ters indicate the rotation along the X, Y, and Z axes. The callback parameters are normalized  to  be
       within the range of -1800 to 1800 inclusive.

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

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