|
261 |
|
262 \ingroup richtext-processing |
|
263 \ingroup shared |
|
264 |
|
265 A QTextDocumentFragment is a fragment of rich text, that can be inserted into |
|
266 a QTextDocument. A document fragment can be created from a |
|
267 QTextDocument, from a QTextCursor's selection, or from another |
|
268 document fragment. Document fragments can also be created by the |
|
269 static functions, fromPlainText() and fromHtml(). |
|
270 |
|
271 The contents of a document fragment can be obtained as plain text |
|
272 by using the toPlainText() function, or it can be obtained as HTML |
|
273 with toHtml(). |
