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 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 parame-ters parameters
ters 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.
