我想在我的演示文稿中添加一个进度条（我的想法来自这个问题），但我相信有某种东西阻止它出现在输出中，而且我似乎无法弄清楚。
这是我的 MWE：

但输出中没有显示任何进度条。我想知道是什么阻止了它显示。
编辑：我想我找到了原因；当我从代码中删除这部分时，进度条就会出现在输出文档中。

但我真的不知道这部分代码是做什么的，因为该模板是大学推荐使用的现成的投影仪演示模板。那么你建议怎么做？
答案1
对于评论来说这太长了。
实际上@samcarter 已经找到了问题所在：事情就是这样出错的
headline您可以通过以下方式将进度条插入模板：\addtobeamertemplate- 您定义一个名为 的新
headline模板。arabic split theme\defbeamertemplate* - 由于您正在调用带星号的版本，BEAMER 将定义进而安装此模板。
- 进度条被删除。
更准确的说，官方的描述是\addtobeamertemplate这样的：
此命令在当前安装为模板 ⟨元素名称⟩ 的文本前添加 ⟨pre-text⟩，在其后添加 ⟨post-text⟩。这允许您以有限的形式修改现有模板。...
如果
安装了新模板，则任何添加的内容都将被删除。另一方面，您可以重复使用此命令来添加多个内容。
官方的描述\defbeamertemplate如下：
此命令为模板 ⟨元素名称⟩ 安装预定义选项。使用此命令后，用户可以使用命令访问预定义模板
\setbeamertemplate。... 带星号的命令版本安装预定义模板选项，但随后立即调用此选项。这对于默认模板很有用。\setbeamertemplate
因此您有几种选择：
*从 中删除\def...，因此新定义的样式将不会被安装并且进度条将保留。- 交换顺序
\add...，\def...这样就没有什么可以抹去进度条了。 - 在新模板的定义中包含进度条。
答案2
用我的一些技巧回答从右到左编写投影仪演示文稿，尤其是列表和文本对齐。
您可能需要更新软件包 比迪烟 确保在从右到左的语言中改变文本的方向
