我想从下面的代码中添加一些像下图这样的箭头。
预期输出
代码
\documentclass{article}
\usepackage{tikz}
\usepackage{xstring}
\tikzset{
raw sort entry/.style={rectangle, thick, draw, node distance=1.5em},
sort entry black/.style={raw sort entry, black, fill=white},
sort entry blackgray/.style={raw sort entry, black, fill=gray!25},
s1/.style={raw sort entry, red, fill=yellow!30},
s2/.style={raw sort entry, blue, fill=green!20},
s3/.style={raw sort entry, violet, fill=orange!25}
}
\newcommand*{\List}[2][sort entry black]{%
\par\noindent%
\edef\listtoprocess{#2}%
\def\ListToProcess{}%
\begin{tikzpicture}[inner sep=2pt, outer sep=0]
\foreach \content in \listtoprocess{
\IfSubStr{\content}{/}{% true
\xdef\ListToProcess{\ListToProcess,\content}
}{% false
\xdef\ListToProcess{\ListToProcess,#1/\content}
}
}
\StrGobbleLeft{\ListToProcess}{1}[\ListToProcess]% removes the first comma (\listToProcess is empty at the start)
\foreach [count=\i] \Style/\Value in \ListToProcess {
\ifnum\i=1\relax
\node [raw sort entry, \Style] (sortnode\i) {\Value};
\else
\node [raw sort entry, right of=sortnode\number\numexpr\i-1\relax, \Style] (sortnode\i) {\Value};
\fi
}
\end{tikzpicture}%
}
\begin{document}
\List[sort entry blackgray]{1, 2, 3, s1/1, s1/2, s1/3, 1, 2, 3}
\bigskip
\List[sort entry blackgray]{1, 2, 3, s1/1, s1/2, s1/3, 1, 2, 3}
\end{document}
答案1
添加
remember picture
对tikzpicture
环境两种内部样式/键:
/qrr/default
和/qrr/name row
由
- 两种外部风格:
default
和name row
。
name row
最初是空白的,因此节点被命名为-1
、-2
、...。
默认的默认样式是sort entry black
(如前面在可选\List
参数中所述)。另请参阅代码中的注释。
代码
\documentclass{article}
\usepackage{tikz}
\usepackage{xstring}
\usetikzlibrary{calc}
\tikzset{
raw sort entry/.style={rectangle, thick, draw, node distance=1.5em},
sort entry black/.style={raw sort entry, black, fill=white},
sort entry blackgray/.style={raw sort entry, black, fill=gray!25},
s1/.style={raw sort entry, red, fill=yellow!30},
s2/.style={raw sort entry, blue, fill=green!20},
s3/.style={raw sort entry, violet, fill=orange!25},
/qrr/default/.style=sort entry black,
name row/.initial={},
default/.style={/qrr/default/.style={#1}},
|-|/.style={
to path={
let \p1=(\tikztostart),
\p2=(\tikztotarget) in
-- (\x1,.5*\y1+.5*\y2) -- (\x2,.5*\y1+.5*\y2) \tikztonodes
-- (\tikztotarget)
}
}
}
% you can leave the default value for the optional argument blank
% as the value of "/qrr/default" is taken anyway
% (but you could make different \List macros
% with different default default values).
\newcommand*{\List}[2][default=sort entry black]{%
\tikzset{#1}%
\par\noindent%
\edef\listtoprocess{#2}%
\pgfkeysgetvalue{name row}{\rowname}
\def\ListToProcess{}%
\begin{tikzpicture}[remember picture,inner sep=2pt, outer sep=0]
\foreach \content in \listtoprocess{
\IfSubStr{\content}{/}{% true
\xdef\ListToProcess{\ListToProcess,\content}
}{% false
\xdef\ListToProcess{\ListToProcess,{/qrr/default}/\content}
}
}
\StrGobbleLeft{\ListToProcess}{1}[\ListToProcess]% removes the first comma (\listToProcess is empty at the start)
\foreach [count=\i] \Style/\Value in \ListToProcess {
\ifnum\i=1\relax
\node [raw sort entry, \Style] (\rowname-\i) {\Value};
\else
\node [raw sort entry, right of=\rowname-\number\numexpr\i-1\relax, \Style] (\rowname-\i) {\Value};
\fi
}
\end{tikzpicture}%
}
\begin{document}
\List[default=sort entry blackgray, name row=a]{1, 2, 3, s1/1, s1/2, s1/3, 1, 2, 3}
\bigskip
\List[default=sort entry blackgray, name row=b]{1, 2, 3, s1/1, s1/2, s1/3, 1, 2, 3}
\tikz[overlay,remember picture] \draw[thick, shorten >=\pgflinewidth,->] (a-7.south) to[|-|] (b-9.north);
\end{document}
