221 \brief The QTextDocument class holds formatted text.-
222-
223 \ingroup richtext-processing-
224-
225-
226 QTextDocument is a container for structured rich text documents, providing-
227 support for styled text and various types of document elements, such as-
228 lists, tables, frames, and images.-
229 They can be created for use in a QTextEdit, or used independently.-
230-
231 Each document element is described by an associated format object. Each-
232 format object is treated as a unique object by QTextDocuments, and can be-
233 passed to objectForFormat() to obtain the document element that it is-
234 applied to.-
235-
236 A QTextDocument can be edited programmatically using a QTextCursor, and-
237 its contents can be examined by traversing the document structure. The-
238 entire document structure is stored as a hierarchy of document elements-
239 beneath the root frame, found with the rootFrame() function. Alternatively,-
240 if you just want to iterate over the textual contents of the document you-
241 can use begin(), end(), and findBlock() to retrieve text blocks that you-
242 can examine and iterate over.-
243-
244 The layout of a document is determined by the documentLayout();-
245 you can create your own QAbstractTextDocumentLayout subclass and-
246 set it using setDocumentLayout() if you want to use your own-
247 layout logic. The document's title and other meta-information can be-
248 obtained by calling the metaInformation() function. For documents that-
249 are exposed to users through the QTextEdit class, the document title-
250 is also available via the QTextEdit::documentTitle() function.-
251-
252 The toPlainText() and toHtml() convenience functions allow you to retrieve the-
253 contents of the document as plain text and HTML.-
254 The document's text can be searched using the find() functions.-
255-
256 Undo/redo of operations performed on the document can be controlled using-
257 the setUndoRedoEnabled() function. The undo/redo system can be controlled-
258 by an editor widget through the undo() and redo() slots; the document also-
259 provides contentsChanged(), undoAvailable(), and redoAvailable() signals-
260 that inform connected editor widgets about the state of the undo/redo-
261 system. The following are the undo/redo operations of a QTextDocument:-
262-
263 \list-
264 \li Insertion or removal of characters. A sequence of insertions or removals-
265 within the same text block are regarded as a single undo/redo operation.-
266 \li Insertion or removal of text blocks. Sequences of insertion or removals-
267 in a single operation (e.g., by selecting and then deleting text) are-
268 regarded as a single undo/redo operation.-
269 \li Text character format changes.-
270 \li Text block format changes.-
271 \li Text block group format changes.-
