glutSpaceballMotionFunc(3GLUT)GLUTglutSpaceballMotionFunc(3GLUT)NAMEglutSpaceballMotionFunc - 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.
DESCRIPTIONglutSpaceballMotionFunc 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.
