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 cur-
rent 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 disables the generation of
Spaceball motion callbacks. When a new window is created, no Spaceball
motion callback is initially registered.
