The pointer should normally be left to the user.If you do use this function, however, it generates events just as if the userhad instantaneously moved the pointer from one position to another.Note that you cannot use<B>XWarpPointer()</B>to move the pointer outside the confine_to window of an active pointer grab.An attempt to do so will only move the pointer as far as the closest edge of theconfine_to window. <P><B>XWarpPointer()</B>can generate a<B>BadWindow</B> error.<H2>Diagnostics</H2><TABLE><TR><TD><B>BadWindow</B><TD>A value for a Window argument does not name a defined Window.</TABLE><H2>See also</H2><B><A HREF="XSetInputFocus.html">XSetInputFocus()</A></B>,"<A HREF="moving-pointer.html">Moving the Pointer</A>".<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
