有没有办法在 QTextEdit 中显示堆叠文本

Question

Is there a way to display stacked text in a QTextEdit? By stacked text, I mean fraction, or exponent

Is there a way to achieve this without table or html conversion?

Answer 1

Qt supports a subset of HTML in its text handling. By default QTextEdit's acceptRichText property is true, so you should be able to set it's text to this:

"1<sup>1</sup>&frasl;<sub>2</sub>"

And it should display 1.5 as a fraction.

Answer 2

AFAIK, Qt is using Unicode, and UTF-8 does have glyphs like ½ (ie U+00BD VULGAR FRACTION ONE HALF ).

However, I would indeed recommend switching to HTML.

You might also study the source code of Qt (it is open source) and subclass QTextEdit as wanted
