glutSpaceballMotionFunc(3GLUT) GLUTglutSpaceballMotionFunc(3GLUT)

NAME
glutSpaceballMotionFunc - sets the Spaceball motion call-
back 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 Spaceball motion callbacks will be gener-
ated.

Passing NULL to glutSpaceballMotionFunc disables the gen-
eration of Spaceball motion callbacks. When a new window
is created, no Spaceball motion callback is initially reg-
istered.
