The QPlainTextDocumentLayout class implements a plain text layout for QTextDocument

A QPlainTextDocumentLayout is required for text documents that can be display or edited in a QPlainTextEdit 。见 QTextDocument.setDocumentLayout ().

QPlainTextDocumentLayout uses the QAbstractTextDocumentLayout API that QTextDocument requires, but redefines it partially in order to support plain text better. For instances, it does not operate on vertical pixels, but on paragraphs (called blocks) instead. The height of a document is identical to the number of paragraphs it contains. The layout also doesn't support tables or nested frames, or any sort of advanced text layout that goes beyond a list of paragraphs with syntax highlighting.
