如何将 QTextEdit 拆分为页面? [英] How to split QTextEdit into pages?

问题描述

我正在使用来自 C++ Qt5 的 QTextEdit.我想在数字页面中正确拆分和显示富文本，类似于在 Microsoft Word 中的处理方式.我试过 document->setPageSize，但这对我不起作用 - 文本仍然显示在一个连续的页面中.

I'm using QTextEdit from C++ Qt5. I want to properly split and show rich text in numerated pages similarly to how it's done in Microsoft Word. I've tried document->setPageSize, however that does not work for me - text is still shown in one continuous page.

推荐答案

AFAIK QTextEdit 不支持字处理器风格的页面"概念.相反，QTextEdit 是围绕编辑和查看连续文档而设计的，其唯一的描述是在块"级别(即段落).

AFAIK QTextEdit doesn't support the word-processor-style concept of "pages". Rather, QTextEdit is designed around editing and viewing a continuous document, whose only delineation is at the level of "blocks" (i.e. paragraphs).

请注意 QTextDocument 类:

Note this telling comment in the QTextDocument::print(QPagedPaintDevice *) const method-documentation of the QTextDocument class:

如果文档没有分页，例如在一个 QTextEdit，然后创建文档的临时副本并副本根据油漆的大小分成多页设备的 paperRect().

If the document is not paginated, like for example a document used in a QTextEdit, then a temporary copy of the document is created and the copy is broken into multiple pages according to the size of the paint device's paperRect().
