箭头的绝对定位

Question

我尝试在文本矩形的右侧放置一个箭头，但不起作用。以下是我所得到的：

\documentclass[compress,blue]{beamer}
\mode<presentation>
\usetheme{Warsaw}
\definecolor{azure}{RGB}{74,100,217}
\useoutertheme[subsection=false]{smoothbars}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{tikz}
\usetikzlibrary{shapes.misc, fit, arrows}
\usetikzlibrary{shapes.callouts, shapes.symbols}

\tikzset{product size/.style={minimum width=1cm, 
    minimum height=1cm,
    text height=1ex,
  },
  product/.style={
    draw,signal, 
    signal to=east, 
    signal from=west,
    product size,
    fill=azure,
    draw=gray!50!white,
    text=white,
 },
}

\begin{document}

\frame{\frametitle{test...}

\begin{tikzpicture}

\node (1-t) at (10,12.2) [draw, minimum width=6cm,minimum height=1.2cm, text width=5.8cm, inner sep = 1pt] {She sells seashells by the seashore,};
\node (2-t) at (10,10.5) [draw, minimum width=6cm,minimum height=1.2cm, text width=5.8cm] {shells she sells are sure seashells,};
\node (3-t) at (10,8.7) [draw, minimum width=6cm,minimum height=1.2cm, text width=5.8cm] {so if she sells shells on the seashore,};
\node (4-t) at (10,6.9) [draw, minimum width=6cm,minimum height=1.2cm, text width=5.8cm] {I am sure she sells seashore shells.};

\node[product] (map) at (10, 12) {Input};

\end{tikzpicture}
}

\end{document}

我该如何定位箭头？

Answer 1

请参阅以下解决方案：

\documentclass[compress,blue]{beamer}
\mode<presentation>
\usetheme{Warsaw}
\definecolor{azure}{RGB}{74,100,217}
\useoutertheme[subsection=false]{smoothbars}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{tikz}
\usetikzlibrary{calc, chains, positioning, shapes}

\tikzset{product size/.style={minimum width=1cm,
    minimum height=1cm,
    text height=1ex,
  },
  product/.style={
    draw,signal,
    signal to=east,
    signal from=west,
    product size,
    fill=azure,
    draw=gray!50!white,
    text=white,
 },
}

\begin{document}

\frame{\frametitle{test...}
    \begin{tikzpicture}[
 node distance = 3mm and 10 mm,
   start chain = going below, 
    box/.style = {draw, minimum height=1.2 cm, text width=5.9cm, 
                  on chain}
                        ]

\node (1-t) [box] {She sells seashells by the seashore,};
\node (2-t) [box] {shells she sells are sure seashells,};
\node (3-t) [box] {so if she sells shells on the seashore,};
\node (4-t) [box] {I am sure she sells seashore shells.};
%
\node[product, right=of $(1-t.east)!0.5!(4-t.east)$] (map) {Input};
\end{tikzpicture}
}

\end{document}

我尝试使用两个 TikZ 库稍微优化您的代码：calc和\chains。positioning得到的结果是：
