glutButtonBoxFunc(3GLUT)	     GLUT	      glutButtonBoxFunc(3GLUT)

NAME
       glutButtonBoxFunc  - sets the dial & button box button callback for the
       current window.

SYNTAX
       void glutButtonBoxFunc(void (*func)(int button, int state));

ARGUMENTS
       func	 The new button	box callback function.

DESCRIPTION
       glutButtonBoxFunc sets the dial & button	box button  callback  for  the
       current	window.	 The dial & button box button callback for a window is
       called when the window has dial & button	 box  input  focus  (normally,
       when  the  mouse	is in the window) and the user generates dial &	button
       box button presses. The button parameter	 will  be  the	button	number
       (starting  at  one).  The number	of available dial & button box buttons
       can be determined with glutDeviceGet(GLUT_NUM_BUTTON_BOX_BUTTONS).  The
       state  is  either  GLUT_UP or GLUT_DOWN indicating whether the callback
       was due to a release or press respectively.

       Registering a dial & button box button callback when a  dial  &	button
       box  device  is	not available is ineffectual and not an	error. In this
       case, no	dial & button box button callbacks will	be generated.

       Passing NULL to glutButtonBoxFunc disables the  generation  of  dial  &
       button  box  button  callbacks. When a new window is created, no	dial &
       button box button callback is initially registered.
