The QPagedPaintDevice 類是支持多個頁麵的描繪設備的錶示。
分頁描繪設備用於為打印或像 PDF 的格式生成輸齣。 QPdfWriter and QPrinter inherit from it.
This enum type lists the available page sizes as defined in the Postscript PPD standard. These values are duplicated in QPageSize and QPrinter.

Due to historic reasons QPageSize::Executive is not the same as the standard Postscript and Windows Executive size, use QPageSize::ExecutiveStandard 代替。
The Postscript standard size QPageSize::Folio is different to the Windows DMPAPER_FOLIO size, use the Postscript standard size QPageSize::FanFoldGermanLegal if needed.
The PdfVersion enum describes the version of the PDF file that is produced by QPrinter or QPdfWriter .
| 常量 | 值 | 描述 |
|---|---|---|
QPagedPaintDevice::PdfVersion_1_4
|
0
|
産生 PDF 1.4 兼容文檔。 |
QPagedPaintDevice::PdfVersion_A1b

QPagedPaintDevice::PdfVersion_1_6
|
2
|
産生 PDF 1.6 兼容文檔。該值在 Qt 5.12 添加。 |

[pure virtual]
bool
QPagedPaintDevice::
newPage
()
開始新頁麵。返迴
true
當成功時。
返迴當前頁麵的布局。使用此方法以訪問當前 QPageSize , QPageLayout::Orientation , QMarginsF ,fullRect() 和 paintRect()。
注意:不可以在返迴對象上使用 setter,必須單獨調用 QPagedPaintDevice setter 或使用 setPageLayout ().
該函數在 Qt 5.3 引入。
另請參閱 setPageLayout (), setPageSize (), setPageOrientation (),和 setPageMargins ().
Returns the currently used page size.
另請參閱 setPageSize ().
返迴頁麵尺寸 (以毫米為單位)。
另請參閱 setPageSizeMM ().

The margins are purely a hint to the drawing method. They don't affect the coordinate system or clipping.
另請參閱 margins ().
將頁麵布局設為 newPageLayout .
應先調用這當調用 QPainter::begin (),或立即調用在調用 newPage () 以將新頁麵布局應用到新頁麵之前。不應調用任何描繪方法,在調用 setPageLayout() 和 newPage () 之間因為可能使用瞭錯誤的描繪規格。
返迴 true 若頁麵布局被成功設為 newPageLayout .
該函數在 Qt 5.3 引入。
另請參閱 pageLayout ().
Set the page margins 在當前頁麵布局單位。
應先調用這當調用 QPainter::begin (),或立即調用在調用 newPage () 以將新邊距應用到新頁麵之前。不應調用任何描繪方法,在調用 setPageMargins() 和 newPage () 之間因為可能使用瞭錯誤的描繪規格。
要獲取當前頁麵邊距,使用 pageLayout ().pageMargins().
返迴 true 若頁麵邊距被成功設為 margins .
該函數在 Qt 5.3 引入。
另請參閱 pageLayout ().
Set the page margins 定義以給定 units .
應先調用這當調用 QPainter::begin (),或立即調用在調用 newPage () 以將新邊距應用到新頁麵之前。不應調用任何描繪方法,在調用 setPageMargins () 和 newPage () 之間因為可能使用瞭錯誤的描繪規格。
要獲取當前頁麵邊距,使用 pageLayout ().pageMargins().

該函數在 Qt 5.3 引入。
另請參閱 pageLayout ().
設置頁麵 orientation .
頁麵取嚮用於定義頁麵大小的取嚮,當獲取頁麵矩形時。
應先調用這當調用 QPainter::begin (),或立即調用在調用 newPage () 以將新取嚮應用到新頁麵之前。不應調用任何描繪方法,在調用 setPageOrientation() 和 newPage () 之間因為可能使用瞭錯誤的描繪規格。
要獲取當前 QPageLayout::Orientation 使用 pageLayout ().pageOrientation().
返迴 true 若頁麵取嚮被成功設為 orientation .
該函數在 Qt 5.3 引入。
另請參閱 pageLayout ().
將頁麵大小設為 pageSize .
要獲取當前 QPageSize 使用 pageLayout (). pageSize ().
應先調用這當調用 QPainter::begin (),或立即調用在調用 newPage () 以將新頁麵尺寸應用到新頁麵之前。不應調用任何描繪方法,在調用 setPageSize() 和 newPage () 之間因為可能使用瞭錯誤的描繪規格。
