Name

glutVisibilityFunc - Sets the Visibility callback for the current window.

Library

OpenGLUT - deprecated

Synopsis

#include <openglut.h>

void

glutVisibilityFunc(void( *callback )( int status ));

Parameters

callback Client hook for visibility changes.

Description

OpenGLUT may call this function when your window's visbility status has changed. status can take on two values: GLUT_NOT_VISIBLE or GLUT_VISIBLE . If any pixel of your window (including descendants) is visible, your window is GLUT_VISIBLE .

The callback is bound to the current window .

Caveats

This is not a polling mechanism. You are only informed of transitions that OpenGLUT observes while your callback is in place.

This function appears to be superceded by glutWindowStatusFunc().

This callback is mutually exclusive of glutWindowStatusFunc().
