Detailed Description

\reentrant

\inmodule QtPrintSupport

The QPrintEngine class defines an interface for how QPrinter interacts with a given printing subsystem.

The common case when creating your own print engine is to derive from both QPaintEngine and QPrintEngine. Various properties of a print engine are given with property() and set with setProperty().

Member Enumeration Documentation

◆ PrintEnginePropertyKey

enum QPrintEngine::PrintEnginePropertyKey

This enum is used to communicate properties between the print engine and QPrinter.

A property may or may not be supported by a given print engine.

\value PPK_CollateCopies A boolean value indicating whether the printout should be collated or not.

\value PPK_ColorMode Refers to QPrinter::ColorMode, either color or monochrome.

\value PPK_Creator A string describing the document's creator.

\value PPK_Duplex A boolean value indicating whether both sides of the printer paper should be used for the printout.

\value PPK_DocumentName A string describing the document name in the spooler.

\value PPK_FontEmbedding A boolean value indicating whether data for the document's fonts should be embedded in the data sent to the printer.

\value PPK_FullPage A boolean describing if the printer should be full page or not.

\value PPK_NumberOfCopies Obsolete. An integer specifying the number of copies. Use PPK_CopyCount instead.

\value PPK_Orientation Specifies a QPageLayout::Orientation value.

\value PPK_OutputFileName The output file name as a string. An empty file name indicates that the printer should not print to a file.

\value PPK_PageOrder Specifies a QPrinter::PageOrder value.

\value PPK_PageRect A QRect specifying the page rectangle

\value PPK_PageSize Obsolete. Use PPK_PaperSize instead.

\value PPK_PaperRect A QRect specifying the paper rectangle.

\value PPK_PaperSource Specifies a QPrinter::PaperSource value.

\value PPK_PaperSources Specifies more than one QPrinter::PaperSource value.

\value PPK_PaperName A string specifying the name of the paper.

\value PPK_PaperSize Specifies a QPrinter::PaperSize value.

\value PPK_PrinterName A string specifying the name of the printer.

\value PPK_PrinterProgram A string specifying the name of the printer program used for printing,

\value PPK_Resolution An integer describing the dots per inch for this printer.

\value PPK_SelectionOption

\value PPK_SupportedResolutions A list of integer QVariants describing the set of supported resolutions that the printer has.

\value PPK_WindowsPageSize An integer specifying a DM_PAPER entry on Windows.

\value PPK_CustomPaperSize A QSizeF specifying a custom paper size in the QPrinter::Point unit.

\value PPK_PageMargins A QList<QVariant> containing the left, top, right and bottom margin values in the QPrinter::Point unit.

\value PPK_CopyCount An integer specifying the number of copies to print.

\value PPK_SupportsMultipleCopies A boolean value indicating whether or not the printer supports printing multiple copies in one job.

\value PPK_QPageSize Set the page size using a QPageSize object.

\value PPK_QPageMargins Set the page margins using a QPair of QMarginsF and QPageLayout::Unit.

\value PPK_QPageLayout Set the page layout using a QPageLayout object.

\value PPK_CustomBase Basis for extension.
