Unless a specific range is specified for an argument, the full range defined by the argument's type is accepted. Any argument defined as a set of alternatives can generate this error.</TABLE><H2>See also</H2><B><A HREF="XGetFontPath.html">XGetFontPath()</A></B>,<B><A HREF="XFreeFontPath.html">XFreeFontPath()</A></B>,<B><A HREF="../graphics/font-metrics/XListFonts.html">XListFonts()</A></B>,<B><A HREF="../graphics/font-metrics/XLoadFont.html">XLoadFont()</A></B>,"<A HREF="font-search-path.html">Setting and Retrieving the Font Search Path</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
