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 cur-
rent 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 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.
