尝试使用 ocg 层构建可扩展宏，我面临着相当令人不安的问题，我无法弄清楚，因此来这里寻求专家的帮助......
我正在使用宏插入一些 tikzpicture 内容。此内容的可见性由以下方式控制：奥克姆来自ocgx2包。在主文件中，我想声明一次对象可能隐藏的层。为此，我使用创建了一个层列表解释3以便在宏中使用它。
问题：只要手动给出层列表，一切都运行良好，但是，只要我将列表传递给 expl3 列表（和 keyval 值），它就会中断。
这是一个最小的例子，我确实需要保留其结构：
\documentclass{article}
\usepackage[tikz]{ocgx2}
\usepackage{keyval}
\makeatletter
\define@key{hidencircle}{trigger}{\def\hidencircle@trigger{#1}}
\newcommand{\hidencircle}[2][]{%
\setkeys{hidencircle}{#1}% Set the keys
\begin{tikzpicture}[overlay,shift={(2.75,1)}]
%%%%%%%%%%%%%% Not Working
\tikzstyle{HCocmd}=[ocmd={visibility=\Not{\Or{\hidencircle@trigger}}}]
%%%%%%%%%%%%%% Does Work
%\tikzstyle{HCocmd}=[ocmd={visibility=\Not{\Or{test1,test2}}}]
\begin{scope}[HCocmd]
\node[circle,fill=red,text=white,text width=1cm]{\bf #2};
\end{scope}
\end{tikzpicture}
}
\makeatother
\ExplSyntaxOn
\NewDocumentCommand{\createlist}{mm}
{\seq_new:c { g_#1_seq }
\seq_gset_from_clist:cn { g_#1_seq } { #2 }}
\NewDocumentCommand{\ocglist}{m}
{\seq_use:cn {g_#1_seq} {,}}
\ExplSyntaxOff
\begin{document}
\createlist{trig}{test1,test2}
\hidencircle[trigger=\ocglist{trig}]{Here I am!}
\tikz{
\begin{scope}[ocg={ref=test1,status=on}]
\node[red](I1){\small circle set invisible};
\end{scope}
\begin{scope}[ocg={ref=test2,status=on}]
\node[blue,anchor=west](I2)at(I1.east){\small circle set invisible};
\end{scope}
\node[switch ocg={test1},fill=green,text=red] (I3)at([yshift=-.5cm]I1.south) {show it: step 1};
\node[switch ocg={test2},fill=green,anchor=west,text=blue] at([xshift=.25cm]I3.east) {show it: step 2};
}
\end{document}
输出如下：
而圆圈可能无法显示！我是 ocgx 和 expl3 的新手，如能得到任何帮助我将不胜感激。
附言：我很好奇你能用 ocgx 做什么。如果有其他例子就更好了。

还有一种可能性：三个新命令\nxAnd，\nxOr，\nxNot允许我们定义基于任意布尔表达式的 TikZ 可见性设置样式，如下所示
\defVisibilityStyle{HCocmd}{\nxNot{\nxOr{\hidencircle@trigger}}}
完整示例：
\documentclass{article}
\usepackage[tikz]{ocgx2}
\usepackage{keyval}
\makeatletter
\define@key{hidencircle}{trigger}{\def\hidencircle@trigger{#1}}%
\newcommand{\hidencircle}[2][]{%
\setkeys{hidencircle}{#1}% Set the keys
\begin{tikzpicture}[overlay,shift={(2.75,1)}]
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\defVisibilityStyle{HCocmd}{\nxNot{\nxOr{\hidencircle@trigger}}}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{scope}[HCocmd]
\node[circle,fill=red,text=white,text width=1cm]{\bf #2};
\end{scope}
\end{tikzpicture}
}
\makeatother
\ExplSyntaxOn
\NewDocumentCommand{\createlist}{mm}
{\seq_new:c { g_#1_seq }
\seq_gset_from_clist:cn { g_#1_seq } { #2 }}

您正在努力将您的值隐藏在不同层（部分不可扩展）的命令后面。如果展开所有内容，它就会起作用：
\documentclass{article}
\usepackage[tikz]{ocgx2}
\usepackage{keyval}
\makeatletter
\define@key{hidencircle}{trigger}{\edef\hidencircle@trigger{#1}}%<-- edef
\newcommand{\hidencircle}[2][]{%
\setkeys{hidencircle}{#1}% Set the keys
\begin{tikzpicture}[overlay,shift={(2.75,1)}]
\tikzstyle{HCocmd}=[ocmd={visibility=\expandafter\Not\expandafter{\expandafter\Or\expandafter{\hidencircle@trigger}}}] %<--
%%%%%%%%%%%%%% Does Work
%\tikzstyle{HCocmd}=[ocmd={visibility=\Not{\Or{test1,test2}}}]
\begin{scope}[HCocmd]
\node[circle,fill=red,text=white,text width=1cm]{\bf #2};
\end{scope}
\end{tikzpicture}
}
\makeatother
\ExplSyntaxOn
\NewDocumentCommand{\createlist}{mm}
{\seq_new:c { g_#1_seq }
\seq_gset_from_clist:cn { g_#1_seq } { #2 }}
\NewExpandableDocumentCommand{\ocglist}{m} %<---
{\seq_use:cn {g_#1_seq} {,}}
\ExplSyntaxOff
\begin{document}
\createlist{trig}{test1,test2}
\hidencircle[trigger=\ocglist{trig}]{Here I am!}
\tikz{
\begin{scope}[ocg={ref=test1,status=on}]
\node[red](I1){\small circle set invisible};
\end{scope}
\begin{scope}[ocg={ref=test2,status=on}]
\node[blue,anchor=west](I2)at(I1.east){\small circle set invisible};
\end{scope}
\node[switch ocg={test1},fill=green,text=red] (I3)at([yshift=-.5cm]I1.south) {show it: step 1};
\node[switch ocg={test2},fill=green,anchor=west,text=blue] at([xshift=.25cm]I3.east) {show it: step 2};
}
\end{document}
