PyQt5 设置 QTextEdit 文档边距（不断）

Question

I would like to set a permanent margin in QTextEdit. And I found out about self.document().rootFrame() . I tried to set the left and right margin, however, the placeholder text is not adapting the margin same with clearing the text using self.clear()

Answer 1

Try setting QTextDocument::setDocumentMargin() https://doc.qt.io/qt-5/qtextdocument.html#documentMargin-prop , which you can access by calling QTextEdit::document() https://doc.qt.io/qt-5/qplaintextedit.html#document , or QTextEdit::setViewportMargins() https://doc.qt.io/qt-5/qabstractscrollarea.html#setViewportMargins . I am not sure which one will work best in your case. You need to try it.
