QTextEdit 中的水平线
我正在尝试在 QTextDocument 中放置一条水平线。我使用 HTML 进行格式化。为了画出我想要的线条，我自然地使用了
这些样式似乎不适用于 hr 元素，那么是否有一个简单的解决方法可以在我的文档中添加水平黑线？
谢谢。
I'm trying to put an horizontal line in a QTextDocument. I'm using HTML for the formatting. To draw the line I want, I naturally used the <hr /> tag. But the line is drawn gray and and I'd like to change its color to black.
The styles doesn't seem to apply on the hr element, so is there a simple workaround to have horizontal black line in my document?
Thanks.

因此，最好的（在 HTML/css 和 QTextDocument 中）是避免
Coming from HTML,
<hr>does not really have the ability to be colored or formatted. IE did it with color, Mozilla with background-color etc.So the best (both in HTML/css and QTextDocument) is to avoid
<hr>and take instead any very small element, size it appropriately and give it a border and a background-color of same color as the border. E.g. a table row. I can dig up some code tomorrow or the day after - I have done this before so it must be somewhere.作为解决方法，您可以使用一些像素高度 div 以及适当的背景颜色。
As a workaround you can use some pixels height div with appropriate background-color.
