DESCRIPTION

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

The callback is bound to the Bf Li
 current window Ef
 .

 

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This function appears to be superceded by glutWindowStatusFunc().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().
