节点位置与列表覆盖

Question

我正在尝试在代码清单上添加标签。我将有一个标记为“设备 A”的清单和一个标记为“设备 B”的清单。

我希望将标签绘制在列表的某个角落。我尝试使用 tikz 覆盖层执行此操作并成功。

但是，当列表是浮点数，并且太大而无法容纳在文本中时，乳胶会将其移动到另一页，tikz 的位置是错误的，并且节点会被绘制在我的列表最初的位置，我想。

我验证了这是由于乳胶移动列表造成的，因为 pageclear 解决了这个问题。

我该怎么做才能使 tikz 位置正确？

将 放入环境\tikz[overlay, remember picture]{... {Device A};}中lstlisting，在 引入的转义 LaTeX 代码中escapechar，似乎可以实现您想要的效果。我还切换到\usetikzlibrary{tikzmark}以便使用标准\tikzmark命令（否则，使用您的自定义定义，当您开始使用依赖于标准的包时可能会遇到问题\tikzmark）。

\documentclass{article}
\usepackage{listings}
\usepackage{tikz}
\usetikzlibrary{tikzmark}
