NAME
glutOverlayDisplayFunc -- 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.
