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