#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

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.
