来自父级[虚线]的边会使节点本身变为虚线？

来自父级[虚线]的边会使节点本身变为虚线？

我有一个类似的问题，如下所问：如何设置树中单个边的样式（TikZ）？

我有一棵树，用 tikz 构建。我想将一些单边设置为虚线，而不是实线。所以我按照上面的帖子中提到的做了，确实有效，但奇怪的是，节点本身的边缘以及具有传入虚线边缘的节点也是虚线。为什么？

这是上面提到的线程中的示例，更改为虚线边缘：

\documentclass{article}
\usepackage{tikz}
\begin{document}
    \begin{tikzpicture} [
    level 1/.style={sibling distance = 2cm, level distance = 1cm},
    level 2/.style={sibling distance = 1cm},
    level 3/.style={sibling distance = 1cm},
    every node/.style={circle, draw=black,thin, minimum size = 0.5cm},
    emph/.style={edge from parent/.style={dashed,red,very thick,draw}},
    norm/.style={edge from parent/.style={solid,black,thin,draw}}
    ]

    \begin{scope}[xshift=6cm]
    \node{} 
    child[emph] { node {}
        child[norm] { node {} }
        child[norm] { node {}
            child[emph] { node {} }
            child { node {} }
        }
    }
    child { node {}
        child { node {} }
        child { node {} }
    }
    child { node {} }
    ;
    \end{scope}
    \end{tikzpicture}

\end{document}

它看起来是这样的： 在此处输入图片描述

您需要solid添加every nodes/.style

\documentclass{article}
\usepackage{tikz}
\begin{document}
    \begin{tikzpicture} [
    level 1/.style={sibling distance = 2cm, level distance = 1cm},
    level 2/.style={sibling distance = 1cm},
    level 3/.style={sibling distance = 1cm},
    every node/.style={circle,solid, draw=black,thin, minimum size = 0.5cm},
    emph/.style={edge from parent/.style={dashed,red,very thick,draw}},
    norm/.style={edge from parent/.style={solid,black,thin,draw}}
    ]

    \begin{scope}[xshift=6cm]
    \node{} 
    child[emph] { node {}
        child[norm] { node {} }
        child[norm] { node {}
            child[emph] { node {} }
            child { node {} }
        }
    }
    child { node {}
        child { node {} }
        child { node {} }
    }
    child { node {} }
    ;
    \end{scope}
    \end{tikzpicture}

\end{document}
