NAMEglutOverlayDisplayFunc — Defines the display hook for an overlay.
LIBRARY
OpenGLUT - windowcallback
SYNOPSIS
#include <openglut.h>
void
glutOverlayDisplayFunc(void( *callback )( void ));
PARAMETERS
callback Client hook for overlay redisplay.
DESCRIPTION
callback is invoked by OpenGLUT to refresh an overlay, if OpenGLUT
thinks that this is necessary. Generally, very similar to glutDisplay‐
Func(), save that:
- The redisplay is triggered differently.
- OpenGLUT sets the layer for you.
- You do not need to have, and can deregister, this callback.
This callback is bound to both the current window and the layer .
BUGS
OpenGLUT does not implement layers at this time.
