     glutButtonBoxFunc -- Sets a button-box button callback.

LIBRARY
     OpenGLUT - input

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  state  as either  GLUT_UP  or  GLUT_DOWN  .

     The callback is bound to the  current window  .

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.
