UNTITLED LOCAL UNTITLED 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 This function appears to be superceded by glutWindowStatusFunc().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(). SEE ALSO glutWindowStatusFunc(3) Epoch[top]
