glutPostRedisplay(3GLUT)             GLUT             glutPostRedisplay(3GLUT)


NAME

       glutPostRedisplay, glutPostWindowRedisplay - marks the current or
       specified window as needing to be redisplayed.


SYNTAX


       void glutPostRedisplay(void);
       void glutPostWindowRedisplay(int win);


DESCRIPTION

       glutPostRedisplay marks the normal plane of current window as needing
       to be redisplayed.  glutPostWindowRedisplay works the specified window
       as needing to be redisplayed.  After either call, the next iteration
       through glutMainLoop, the window's display callback will be called to
       redisplay the window's normal plane. Multiple calls to
       glutPostRedisplay before the next display callback opportunity
       generates only a single redisplay callback.  glutPostRedisplay may be
       called within a window's display or overlay display callback to re-mark
       that window for redisplay.

       Logically, normal plane damage notification for a window is treated as
       a glutPostRedisplay on the damaged window. Unlike damage reported by
       the window system, glutPostRedisplay will not set to true the normal
       plane's damaged status (returned by glutLayerGet(GLUT_NORMAL_DAMAGED).

       If the window you want to post a redisplay on is not already current
       (and you do not require it to be immediately made current), using
       glutPostWindowRedisplay is more efficient that calling glutSetWindow to
       the desired window and then calling glutPostRedisplay.
