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. glutPost-WindowRedisplay glutPostWindowRedisplay
WindowRedisplay 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 win-dow's window's
dow'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 dis-play display
play 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.
