253-
254 \ingroup richtext-processing-

256-
257 A QTextDocumentFragment is a fragment of rich text, that can be inserted into-
258 a QTextDocument. A document fragment can be created from a-
259 QTextDocument, from a QTextCursor's selection, or from another-
260 document fragment. Document fragments can also be created by the-
261 static functions, fromPlainText() and fromHtml().-
262-
263 The contents of a document fragment can be obtained as plain text-
264 by using the toPlainText() function, or it can be obtained as HTML-
265 with toHtml().-
