Synopsis
#include <openglut.h>
void
glutButtonBoxFunc(void( *callback )( int button, int state ));
Parameters
callback
Client buttonbox button hook.
Description
A dials-and-buttons box has buttons numbered from 1 to glutDeviceGet(
GLUT_NUM_BUTTON_BOX_BUTTONS),
inclusive. The parameters callback are the
button
and its

as either
GLUT_UP

Caveats
OpenGLUT does not implement button-box support.
Also in contrast, mouse buttons are numbered from 0 in the GLUT API. This is a wrinkle.
