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 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 Space- ball 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. SEE ALSO
