glutWindowStatusFunc - Man Page

OpenGLUT - windowcallback

#include <openglut.h>

void
glutWindowStatusFunc(void( *callback )( int state ));

Client window status hook.

When the visibility status of your window changes, OpenGLUT either invokes the

registered by this function or the Visibility

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:

-

(every pixel visible)
-

(every pixel obscured)
-

(intermediate)

The callback is bound to the


current window
.

Makes glutVisibilityFunc() obsolete.

glutVisibilityFunc(3)

glutPopWindow(3), glutPushWindow(3), glutShowWindow(3), glutVisibilityFunc(3).
