使用 tikz 包在框图中创建容器

Question

我在通过包在流程图内创建容器时遇到了问题tikz。

第一张图片显示的是预期结果，第二张图片显示的是我制作的当前版本。

如何调整容器框高度以及如何将文本放置在“中心”点上方？此外，我在使用该fill=gray命令时遇到了问题：如何修复图层问题，以便容器位于背景中？

这是我当前的代码：

\documentclass[12pt,a4paper]{article}

\usepackage{tikz}

\usetikzlibrary{shapes,arrows,fit}
\tikzstyle{block} = [draw, rectangle, text width=2cm, text centered, minimum height=1.2cm, node distance=3cm]
%\tikzstyle{container} = [draw, rectangle, inner sep=0.3cm, fill=gray]
\tikzstyle{container} = [draw, rectangle, inner sep=0.3cm]

\begin{document}

\begin{figure}[]
  \centering

\begin{tikzpicture}

    \node [block, name=text1] {Text1};
    \node [block, right of=text1] (text2) {Text2};
    \node [block, right of=text2] (text3) {Text3};
    \node [block, right of=text3] (text4) {Text4};
    \node [block, right of=text4] (text5) {Text5};
    \node [container,fit=(text2) (text3) (text4)] (container) {};

    \draw [->] (text1) -- (text2);
    \draw [->] (text2) -- node {} (text3);
    \draw [->] (text3) -- node {} (text4);
    \draw [->] (text4) -- node {} (text5);

\end{tikzpicture}

  \caption{Test.}
\end{figure}

\end{document}

谢谢你！

我找到了一个使用backgroundstikzlibrary 的解决方案。

\documentclass[12pt,a4paper]{article}

\usepackage{tikz}

\usetikzlibrary{shapes,arrows,fit,backgrounds}
\tikzstyle{block} = [draw, rectangle, text width=2cm, text centered, minimum height=1.2cm, node distance=3cm,fill=white]
\tikzstyle{container} = [draw, rectangle, inner sep=0.3cm, fill=gray,minimum height=3cm]
%\tikzstyle{container} = [draw, rectangle, inner sep=0.3cm]
\def\bottom#1#2{\hbox{\vbox to #1{\vfill\hbox{#2}}}}
\tikzset{
  mybackground/.style={execute at end picture={
      \begin{scope}[on background layer]
        \node[] at (current bounding box.north){\bottom{1cm} #1};
        \end{scope}
    }},
}
\begin{document}

\begin{figure}[]
  \centering

\begin{tikzpicture}[mybackground={Box1}]

    \node [block, name=text1] {Text1};
    \node [block, right of=text1] (text2) {\color{red} Text2};
    \node [block, right of=text2] (text3) {\color{blue} Text3};
    \node [block, right of=text3] (text4) {\color{orange} Text4};
    \node [block, right of=text4] (text5) {Text5};
    \begin{scope}[on background layer]
    \node [container,fit=(text2) (text3) (text4)] (container) {};
\end{scope}
    \draw [->] (text1) -- (text2);
    \draw [->] (text2) -- node {} (text3);
    \draw [->] (text3) -- node {} (text4);
    \draw [->] (text4) -- node {} (text5);

\end{tikzpicture}

  \caption{Test.}
\end{figure}

\end{document}
