使用 tcolorbox 定制可破坏的盒子

使用 tcolorbox 定制可破坏的盒子

我使用 tcolorbox 包在 polyglossia 包下在阿拉伯语环境（一种从右到左的语言）中生成彩色框。
我在附件文件中解释了环境示例中的一些命令：这里使用命令“before upper”和“after upper”来包含 tcolorbox 环境中的命令。（我给出了 example_small 环境，用于单行和双行示例，以供任何评论！）在之前，我把命令

\parshape 4
        0pt \dimexpr \hsize-7mm\relax
        0pt \dimexpr \hsize-7mm\relax
        0pt \dimexpr \hsize-7mm\relax
        0pt \hsize

这会将示例的文本向前推 7 毫米，这是示例的前三行（否则节点会叠加在文本上）。您可以在下面看到 tex 文件及其编译。现在，我有几个问题：

1/ 我对长且无标题的示例感到满意，但对于有标题的示例，tcolorbox 在推送的三行中不包括标题行（参见示例 4）。因此，在这种情况下我只想推送两行。我该怎么做？

2/ 对于损坏的示例“Ex.5”，我遇到了第二个问题，其中可以看到在中断处，环境会（自动！）复制标题的节点。这对我来说可能是一个不错的选择，现在我想研究两个选项：a/ 第一个是让环境在中断处复制其节点，然后，我如何在中断处对命令进行排序

    \parshape 4
            0pt \dimexpr \hsize-7mm\relax
            0pt \dimexpr \hsize-7mm\relax
            0pt \dimexpr \hsize-7mm\relax
            0pt \hsize

以行为作为环境的开始？

b/ 第二个选项是禁止此重复。什么选项可以使此示例节点的行为与往常一样，即可中断但不在中断处重复标题？

我给了我的 tex 文件......

我修改了你的例子来回答问题。

对于第一个问题，before upper如果存在标题，则代码会更改，请参阅code={\ifstrempty ...

对于第二个问题， 会underlay根据中断状态而改变。我也将overlay其改为underlay，因为它几乎是相同的，但您可以对同一个框多次使用它，并且它添加的代码不会替换。

虽然不可能有\parshape断点，但可以删除重复的框：

我还建议您使用enhanced jigsaw而不是jigsaw作为您的示例（效果是否可见取决于预览器）。
