如何使用PyQt5在Qt中显示数学排版(MathJax，LaTeX等)? [英] How to display mathematical typesetting (MathJax, LaTeX, etc.) in Qt using PyQt5?
问题描述
我对Qt和PyQt5相当陌生，想在GUI窗口中显示数学排版.具体来说，我希望它能够动态更新.我似乎找不到任何有关如何使用PyQt5进行操作的有用信息.
I am fairly new to Qt and PyQt5 and would like to display mathematical typesetting in a GUI window. Specifically, I would like it to be able to update dynamically. I can't seem to find any helpful information on how to do this with PyQt5.
我已经深入研究了如何做到这一点
I've thoroughly researched how to do this
在此处找到了一个看似相关的答案，但是没有给出解决方案，并且它实际上没有解决在GUI中显示排版数学的问题.
One seemingly relevant answer is found here, but no solution is given and it doesn't actually address the issue of showing the typeset math in a GUI.
在此处找到了另一个看似相关的答案，但使用了PySide(和python 2.7)，并给出了荒唐，不必要的复杂和过时的答案.
Another seemingly relevant answer is found here, but uses PySide (and python 2.7) and gives an absurdly and unecessarily complicated and outdated answer.
推荐答案
我想出了如何以一种非常简单的方式做到这一点.下面给出的示例需要Internet连接才能访问MathJax JS模块.
I figured out how to do this in a manner that is quite easy and simple. The example given below requires internet connectivity to access the MathJax JS module.

首先，导入 QApplication 和 QWebEngineView .
import sys
from PyQt5.QtWidgets import QApplication
from PyQt5.QtWebEngineWidgets import QWebEngineView
然后，编写一个包含HTML代码的多行字符串.该代码应导入MathJax javascript模块.然后，写出数学方程式...
Then, write a multi-line string containing HTML code. The code should import the MathJax javascript module. Then, write your mathematical equation...
pageSource = """
<html><head>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script></head>
<body>
<p><mathjax style="font-size:2.3em">$$u = \int_{-\infty}^{\infty}(awesome)\cdot du$$</mathjax></p>
</body></html>
"""
最后，实例化一个QApplication，实例化一个QWebEngineView，并将WebEngineView设置为显示新编写的HTML代码:
Finally, instantiate a QApplication, instantiate a QWebEngineView, and set the WebEngineView to show your newly written HTML code:
app = QApplication(sys.argv)
webView = QWebEngineView()
webView.setHtml(pageSource)
别忘了在WebEngineView上调用show.
Don't forget to call show on your WebEngineView.
webView.show()
sys.exit(app.exec_())
如果要创建不需要互联网连接即可运行MathJax JS文件的应用，只需复制JS模块并将其另存为字符串即可.
