字体命令中多行文本的 tikz 对齐

Question

为什么不接受像和tikz这样的字体命令内的多行文本？\texttt\textbf

例如，编写文件

\documentclass[tikz]{standalone}

\begin{document}

\begin{tikzpicture}
  % this node works
  \node[draw,align=left] (a) {Normal text\\works.};

  % this node gives an error
  \node[draw,align=left] [below of=a] {\texttt{Typewritter text is\\rejected.}};
\end{tikzpicture}

\end{document}

失败并显示错误

! Undefined control sequence.
\tikz@invoke@collected@onpath ...mmand \tikz@temp 
                                                  \pgf@stop \tikz@node@is@a@...
l.10 ... {\texttt{Typewritter text is\\rejected.}}

这个问题有什么好的解决办法？

Answer 1

在节点属性中指定字体：

\documentclass[tikz]{standalone}

\begin{document}

\begin{tikzpicture}
  \node[draw,align=left] (a) {Normal text\\works.};
  \node[draw,align=left,font=\ttfamily] [below of=a] {Typewriter text is\\not rejected.};
\end{tikzpicture}

\end{document}

Answer 2

添加text width使线路可断开：

\documentclass[tikz]{standalone}

\begin{document}

\begin{tikzpicture}
  % this node works
  \node[draw,align=left] (a) {Normal text\\works.};

  % this node gives an error
  \node[draw,align=left, text width = 3cm] [below of=a] {\texttt{Typewriter text\\is not rejected.}};
\end{tikzpicture}

\end{document}
