(An exposed window region describes a formerly obscured window whose region becomes visible.) Therefore, the X server sends <B><A HREF="expose.html">Expose</A></B> events describing the window and the region of the window that has been exposed.A naive client application usually redraws the entire window. A more sophisticated client application redraws only the exposed region.<H5 ALIGN=right><I>Next: <A HREF="expose.html">Expose Events</A></I></H5><HR><ADDRESS><A HREF="http://tronche.com/">Christophe Tronche</A>, <A HREF="mailto:ch.tronche@computer.org">ch.tronche@computer.org</A></ADDRESS></BODY></HTML>⌨️ 快捷键说明
