QTextDocumentrequires, 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.
