glutSpaceballMotionFunc(3GLUT)					       GLUT					    glutSpaceballMotionFunc(3GLUT)

NAME

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

SYNTAX

       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 normalized 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 Space-
       ball 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.

NAME

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

SYNTAX

       #include <GLUT/glut.h>

       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 parameters 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  Space-
       ball 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.
