glutSpaceballRotateFunc(3GLUT) GLUT glutSpaceballRotateFunc(3GLUT) NAME glutSpaceballRotateFunc - sets the Spaceball rotation callback for the cur- rent 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 win- dow has Spaceball input focus (normally, when the mouse is in the window) and the user generates Spaceball rotations. The x, y, and z callback para- meters indicate the rotation along the X, Y, and Z axes. The callback para- meters 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 ro- tate callbacks will be generated. Passing NULL to glutSpaceballRotateFunc disables the generation of Space- ball rotate callbacks. When a new window is created, no Spaceball rotate callback is initially registered.
