在投影仪框架内移动颜色框

Question

假设我们在以下环境中有一个 tcolorbox：

\documentclass[17pt]{beamer}

\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{pgfkeys}
%
\usepackage{multicol}
\usepackage{graphicx}
\usepackage{multirow}
%
\usepackage{tikz}
\usepackage{tcolorbox}
%
\usepackage{listings}
%
%
\begin{document}
\begin{frame}[fragile]
\begin{tcolorbox}[title=boxtitle,width=250pt, move downward= 10pt]
\begin{lstlisting}[language=TeX]
    code...
\end{lstlisting}    
    Some text
\begin{lstlisting}[language=Java]

more code...
\end{lstlisting}
\end{tcolorbox}
\end{frame}
\end{document}

我怎样才能将tcolorboxI buildt 移动到我想要的位置（在框架中）？我尝试过通过以下方式移动它，[move downwards*= 9pt]但这给了我一个例外：

Package pgfkeys Error: I do not know the key '/tcb/enhanced' and I am going to ignore it. Perhaps you misspelled it. ...h=280pt, boxrule= 2pt, move downward= 10pt]

另外，我看到了一篇关于嵌入tcolorbox“节点”或“tlrbox”内部的帖子，但我不太明白这是如何做到的。

Answer 1

您始终可以将节点包含tcolorbox在内部TikZ并将其放置在某个位置上current page（您需要两次编译才能将框置于所需的位置）。

move downward在 中没有定义为选项tcolorbox，因此出现错误是正常的。
