120 rectangle it occupies is given by rect(), and its direction by-
121 textDirection(). Its position in the text layout is given by-
122 textPosition(), and its format is given by format().-

262 \class QTextLayout-
263 \reentrant-
264-
265 \brief The QTextLayout class is used to lay out and render text.-
266 \inmodule QtGui-
267-
268 \ingroup richtext-processing-
269-
270 It offers many features expected from a modern text layout-
271 engine, including Unicode compliant rendering, line breaking and-
272 handling of cursor positioning. It can also produce and render-
273 device independent layout, something that is important for WYSIWYG-
274 applications.-
275-
276 The class has a rather low level API and unless you intend to-
277 implement your own text rendering for some specialized widget, you-
278 probably won't need to use it directly.-
279-
280 QTextLayout can be used with both plain and rich text.-
281-
282 QTextLayout can be used to create a sequence of QTextLine-
283 instances with given widths and can position them independently-
284 on the screen. Once the layout is done, these lines can be drawn-
285 on a paint device.-
286-
287 The text to be laid out can be provided in the constructor or set with-
288 setText().-
289-
290 The layout can be seen as a sequence of QTextLine objects; use createLine()-
291 to create a QTextLine instance, and lineAt() or lineForTextPosition() to retrieve-
292 created lines.-
293-
294 Here is a code snippet that demonstrates the layout phase:-
295 \snippet code/src_gui_text_qtextlayout.cpp 0-
296-
297 The text can then be rendered by calling the layout's draw() function:-
298 \snippet code/src_gui_text_qtextlayout.cpp 1-
299-
300 For a given position in the text you can find a valid cursor position with-
301 isValidCursorPosition(), nextCursorPosition(), and previousCursorPosition().-
302-
303 The QTextLayout itself can be positioned with setPosition(); it has a-
304 boundingRect(), and a minimumWidth() and a maximumWidth().-

1344 A text line is usually created by QTextLayout::createLine().-
1345-
1346 After being created, the line can be filled using the setLineWidth()-
1347 or setNumColumns() functions. A line has a number of attributes including the-
1348 rectangle it occupies, rect(), its coordinates, x() and y(), its-
1349 textLength(), width() and naturalTextWidth(), and its ascent() and descent()-
1350 relative to the text. The position of the cursor in terms of the-
1351 line is available from cursorToX() and its inverse from-
1352 xToCursor(). A line can be moved with setPosition().-
