259-
260 \ingroup richtext-processing-

262-
263 A QTextDocumentFragment is a fragment of rich text, that can be inserted into-
264 a QTextDocument. A document fragment can be created from a-
265 QTextDocument, from a QTextCursor's selection, or from another-
266 document fragment. Document fragments can also be created by the-
267 static functions, fromPlainText() and fromHtml().-
268-
269 The contents of a document fragment can be obtained as plain text-
270 by using the toPlainText() function, or it can be obtained as HTML-
271 with toHtml().-
