glutButtonBoxFunc - Man Page

Sets a button-box button callback.

Library

OpenGLUT - input

#include <openglut.h>

void
glutButtonBoxFunc(void( *callback )( int button, int state ));

callback

Client buttonbox button hook.

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

GLUT_DOWN

The callback is bound to the

current window
.

OpenGLUT does not implement button-box support.

Also in contrast, mouse buttons are numbered from 0 in the GLUT API. This is a wrinkle.
