添加 tcolorbox 标签时，计数器 tcbbreakpart 会在 2 处阻塞

Question

很长的序列tcolorbox可以分成许多个框。“中断序列的各个部分由计数器 tcbbreakpart 编号。”（手册 4.11 第 363 页）

现在，让我们为每个页面添加一个侧边标签，可以使用tcolorbox或使用 TiKZ 制作。

tcbbreakpart当标签由 TiKZ 制作时，效果很好。

tcbbreakpart当右侧选项卡是 tcolorbox 时，在 2 处停止。

有没有什么办法可以解除柜台的封锁tcbbreakpart？

Answer 1

正如 Ignasi 所写：tcbbreakpart计数器是“唯一的”而不是per-box计数器实体，因此在每个侧边标签框中都会发生重置——一个可能的解决方案是存储计数器值，但这非常棘手。

我已经使用（嗯，我的;-) 包xassoccnt来提供一个存储的计数器，每次计数器增加时都会步进，并在每个侧边标签框之后tcbbreakpart恢复其值。tcbbreakpart

我还将 移到了tab box的底层pagebox，以便摆脱异步发货。

旁注：在大多数情况下，最好定义专门的框而不是\begin{tcolorbox}...\end{tcolorbox}一直使用。
