使用 postaction 定义 tikzstyle

Question

是否可以postaction在tikzstyle命令中使用？如果可以，如何使用？

\documentclass{standalone}
\usepackage[ngerman]{babel}
\usepackage{tikz}
%
\begin{document}
\begin{tikzpicture}
 \tikzstyle{ground/.style}={%
    \draw[postaction={draw,line width=0.35mm,red,dash pattern=on 3pt off 5pt,
          dash phase=4pt,thick}]
    [blue,dash pattern= on 3pt off 5pt,thick,rounded corners]};
 \draw[ground] (0,0) -- (3,3);
\end{tikzpicture}
\end{document}

Answer 1

就我个人而言，我会使用\tikzset，\tikzstyle但总的来说，如果您删除不必要的代码，效果会很好\draw。

\documentclass{standalone}
\usepackage[ngerman]{babel}
\usepackage{tikz}
%
\begin{document}
\begin{tikzpicture}
 \tikzset{ground/.style={%
    postaction={draw,line width=0.35mm,red,dash pattern=on 3pt off 5pt,
          dash phase=4pt,thick},
        blue,dash pattern= on 3pt off 5pt,thick,rounded corners}}
 \draw[ground] (0,0) -- (3,3);
\end{tikzpicture}
\end{document}
