289 \inmodule QtGui-
290 \since 5.3-
291 \brief Describes the size, orientation and margins of a page.-
292-
293 The QPageLayout class defines the layout of a page in a paged document, with the-
294 page size, orientation and margins able to be set and the full page and paintable-
295 page rectangles defined by those attributes able to be queried in a variety of units.-
296-
297 The page size is defined by the QPageSize class which can be queried for page size-
298 attributes. Note that the QPageSize itself is always defined in a Portrait-
299 orientation.-
300-
301 The minimum margins can be defined for the layout but normally default to 0.-
302 When used in conjunction with Qt's printing support the minimum margins-
303 will reflect the minimum printable area defined by the printer.-
304-
305 In the default StandardMode the current margins and minimum margins are-
306 always taken into account. The paintable rectangle is the full page-
307 rectangle less the current margins, and the current margins can only be set-
308 to values between the minimum margins and the maximum margins allowed by-
309 the full page size.-
310-
311 In FullPageMode the current margins and minimum margins are not taken-
312 into account. The paintable rectangle is the full page rectangle, and the-
313 current margins can be set to any values regardless of the minimum margins-
314 and page size.-
