pdfcomment 包中的 pdftooltip：在工具提示中使用 LaTeX 代码

我是一名物理老师，我正在编写一本“问题解决方案书”，其中包含从问题到解决方案的超链接和反向引用 - 所有这些都运行良好。

现在我想引入一些类似“提示”的东西——问题标题处的文本作为工具提示，指出一些可能的解决方案的提示（除了直接点击“解决方案”链接;-)）

我想知道是否可以在 Josef Kleber 包中的命令LaTeX的第二个参数中使用代码。我使用的是2.3a版本。\pdftooltippdfcommentpdflatexpdfcomment

我想要做的是：

使用该\pdftooltip命令，当鼠标移动到相关部分上时，就会出现一个带有蓝色背景颜色的工具提示框。

这是一个最小的工作示例：

\documentclass{book}

\usepackage{xcolor}

\usepackage{pdfcomment}

\begin{document}

\pdftooltip{foo}{%
\colorbox{blue}{%
Hint: What is the definition of foo?}% End of Colorbox
}% End of pdftooltip command

\end{document}

（虽然它可以顺利编译，但是没有给出预期的结果:-(）

但是，没有蓝色背景色，但几乎逐字逐句地写着colorbox……蓝色等文字，并用（大概是）pdf 代码括起来。

我知道，存在数学标记的可能性pdftooltips，但“视觉享受”怎么办？;-)

已编辑：我知道这些软件包fancytooltips，cooltooltips但它们不符合我的意图

答案1

\tooltip[black]{foo}[blue!50]{Hint: What is the definition of foo?}

如果鼠标移到“foo”上，则会显示提示，当鼠标移出时，提示会立即消失。

为了拖动提示，必须单击“foo”。提示仍然可见。将鼠标移到提示上，单击它并移动它。再次单击提示以将其固定在当前位置。

要隐藏提示，请用鼠标擦拭“foo”。

链接文字和提示文字颜色可选。此外，支持pdftex所有常见驱动程序（xetex、 、...）。dvips

建议宽度<tip text>不要大于\linewidth，必要时应<tiptext>放入\parbox。

（代码由 M. Scharrer 编写，来自https://tex.stackexchange.com/a/17808用于计算更宽的提示文本框的初始左移。）
