GLUTWINDOWSTATUSFUNC(3)

NAME
glutWindowStatusFunc - Sets the window status callback.

LIBRARY
OpenGLUT - windowcallback

SYNOPSIS
#include <openglut.h>
void
glutWindowStatusFunc(void( *callback )( int state ));

PARAMETERS

callback Client window status hook.

DESCRIPTION
When the visibility status of your window changes, OpenGLUT either invokes the callback registered by this function or the Visibility callback---or neither, if you have not registered either callback.

This differs from glutVisbilityFunc() in that the callback has three states, rather than two, that it may receive. These states are:

- GLUT_VISIBLE (every pixel visible) - GLUT_FULLY_COVERED (every pixel obscured) - GLUT_HIDDEN (intermediate)

The callback is bound to the current window .

CAVEATS
Makes glutVisibilityFunc() obsolete.
