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);
DESCRIPTIONglutPostRedisplay 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 glutMain
Loop, the window's display callback will be called to
redisplay the window's normal plane. Multiple calls to
glutPostRedisplay before the next display callback oppor
tunity generates only a single redisplay callback. glut
PostRedisplay may be called within a window's display or
overlay display callback to re-mark that window for redis
play.
Logically, normal plane damage notification for a window
is treated as a glutPostRedisplay on the damaged window.
Unlike damage reported by the window system, glutPostRe
display 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 immedi
ately made current), using glutPostWindowRedisplay is more
efficient that calling glutSetWindow to the desired window
and then calling glutPostRedisplay.
