效果非常棒。
现在我想添加另一个箭头，从 到(2)，(3)因此可能会添加
"{3}",
到\LstCon对象（请将的值增加\totalnodes1！），但这会产生丑陋的输出，因为它与“Subject1”冲突。
为了解决这个问题，有人告诉我我需要创造这个新箭头外部循环\foreach位于tikzpicture环境中。因此，我在代码中删除"{3}",并添加了以下三行：
\pgfmathsetmacro{\huenumm}{2*0.75*(1/\totalnodes)}
\definecolor{mycolor2}{hsb}{\huenumm,1,1}
\draw[-latex,mycolor2,very thick] -- ++ (3,0) (2-Title.east) to[manoooh curve=1.6] (3-Title.west);
您只需取消注释给定 MWE 的那些行即可获得以下输出：
看上去好像没有什么问题。
但是，在循环外部添加箭头\foreach会使复选框不可点击：
我想让这个新复选框可以点击。我们该怎么做？
谢谢！！
overfull \hboxPS 此外，由于 ，我收到了坏箱消息\parbox。您能否尝试找出我收到此消息的原因？
答案1
初步估计：有两个不同的数字：
\totalnodes是您将要获得的复选框的数量。\listednodes小于或等于\totalnodes，就是您循环的列表的条目数。
对于每个更复杂的连接，您需要执行额外的范围
\begin{scope}[ocg={name={Arrow<X>},ref=myArrow<X>,status=visible}]
....
\end{scope}
其中是大于和小于或等于 的<X>数字，用于标记额外条目。下面是等于 1（因为列表有两个条目，我们从 0 开始）、等于 2 以及也等于 2 的示例。\listednodes\totalnodes\listednodes\totalnodesX
