如何用两种不同的颜色填充分裂节点？

当我尝试用两种不同的颜色填充分割节点时，我遇到了这个问题。使用rectangle split part fill={red,blue}节点参数后drop shadow，节点会重叠，因为我没有使用该fill=color参数。

我该如何避免这个问题？在此处输入图片描述

肯定有更好的解决方案，但这里有一个快速解决方法：绘制节点两次，第一次带阴影，第二次不带阴影。

2010 年，Mark Wibrow 针对类似的问题向我建议了一种 hack，可以在多部分节点形状的自定义填充中正确显示删除。在您的（现在真正的）mwe 中使用它如下：

\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{positioning,
                shadows,
                shapes.multipart}
\pgfdeclarelayer{foreground}
\pgfdeclarelayer{background}
\pgfsetlayers{background,main,foreground}
\makeatletter
\def\tikz@extra@preaction#1{% hackery which enable preactions 
                            % in multi-part node on a different layer
                            % suggested by Mark Wibrow on c.t.t. (2010)
  {%
    \pgfsys@beginscope%
      \setbox\tikz@figbox=\box\voidb@x%
      \begingroup\tikzset{#1}\expandafter\endgroup%
      \expandafter\def\expandafter\tikz@preaction@layer
\expandafter{\tikz@preaction@layer}%
      \ifx\tikz@preaction@layer\pgfutil@empty%
      \path[#1];% do extra path
      \else%
      \begin{pgfonlayer}{\tikz@preaction@layer}%
      \path[#1];%
      \end{pgfonlayer}
      \fi%
      \pgfsyssoftpath@setcurrentpath\tikz@actions@path% restore
      \tikz@restorepathsize%
    \pgfsys@endscope%
  }%
}
\let\tikz@preaction@layer=\pgfutil@empty
\tikzset{preaction layer/.store in=\tikz@preaction@layer}
\makeatother

\tikzset{% style for multi-part node with dropped shadow on background layer
mpv/.style = {% multi part vertical (node)
    rectangle split,
    rectangle split parts=2,
    rectangle split part fill={#1}, % <-- enable different fill for each node part
    draw, rounded corners, text width=3cm,
    align=center, text=white,
  preaction layer=background,       % <-- prepare layer for drop shadow
    drop shadow}, 
        }

\begin{document}
 \begin{tikzpicture}[node distance = 2mm]
% CONSOLE
\node (n1) [mpv=black!70]
    {
        \textbf{Console}
        \nodepart{two}  Benutzereingaben
    };
% FUNKTIONEN
\node (n2) [mpv={red,blue}, below=of n1]
    {
        \textbf{Funktionen}
        \nodepart[align=left]{two}  \verb+Scripts+ \\
                                    \verb+Format+ \\
                                    \verb+getScripts+ \\
                                    \verb+getCode+
    };
\end{tikzpicture}
\end{document}

您可以将节点名称更改为您在 mwe 中使用的名称。对于节点“Funktionen”的第二部分中的文本，使用verb环境而不是\code{...}命令。如果您更喜欢它们，您可以使用它们。

如您所见，在准备好单独的层之后，drop shadow您只需要添加preaction layer=background到多部分节点样式定义。多部分节点样式对于机器人节点来说是通用的，但是，如果您更喜欢每个节点都有不同的节点样式，则可以按如下方式定义它们：

\tikzset{% 
mpv/.style = {% multi part vertical (node)
    rectangle split,
    rectangle split parts=2,
    draw, rounded corners, text width=3cm,
    align=center, text=white,
  preaction layer=background, 
    drop shadow}, 
abstract/.style = {mpv, fill=black!30},
 comment/.style = {mpv, rectangle split part fill={red,blue}},
        }

然后像在你的 mwe 中一样使用它们：

\node (<node name>) [abstract] {....};
\node (<node name>) [comment, below=of n1] {...};

答案3

投射阴影是如何工作的？路径被存储并重复使用（在移动时）。你可以在背景层上做同样的事情。我的答案是使用use path诡计。
