#include <QPrintEngine>
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().
See also QPaintEngine.
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.
| Constant | Value | Description |
|---|---|---|
| QPrintEngine::PPK_CollateCopies | 0 | A bool value describing wether the printout should be collated or not. |
| QPrintEngine::PPK_ColorMode | 1 | Refers to QPrinter::ColorMode, either color or monochrome. |
| QPrintEngine::PPK_Creator | 2 | |
| QPrintEngine::PPK_DocumentName | 3 | A string describing the document name in the spooler. |
| QPrintEngine::PPK_FullPage | 4 | A boolean describing if the printer should be full page or not. |
| QPrintEngine::PPK_NumberOfCopies | 5 | An integer specifying the number of copies |
| QPrintEngine::PPK_Orientation | 6 | Specifies a QPrinter::Orientation value. |
| QPrintEngine::PPK_OutputFileName | 7 | The output file name as a string. An empty file name indicates that the printer should not print to a file. |
| QPrintEngine::PPK_PageOrder | 8 | Specifies a QPrinter::PageOrder value. |
| QPrintEngine::PPK_PageRect | 9 | A QRect specifying the page rectangle |
| QPrintEngine::PPK_PageSize | 10 | Specifies a QPrinter::PageSize value. |
| QPrintEngine::PPK_PaperRect | 11 | A QRect specifying the paper rectangle. |
| QPrintEngine::PPK_PaperSource | 12 | Specifies a QPrinter::PaperSource value. |
| QPrintEngine::PPK_PrinterName | 13 | A string specifying the name of the printer. |
| QPrintEngine::PPK_PrinterProgram | 14 | A string specifying the name of the printer program used for printing, |
| QPrintEngine::PPK_Resolution | 15 | An integer describing the dots per inch for this printer. |
| QPrintEngine::PPK_SelectionOption | 16 | |
| QPrintEngine::PPK_SupportedResolutions | 17 | A list of integer QVariants describing the set of supported resolutions that the printer has. |
| QPrintEngine::PPK_WindowsPageSize | 18 | An integer specifying a DM_PAPER entry on Windows. |
| QPrintEngine::PPK_SuppressSystemPrintStatus | 20 | Suppress the built-in dialog for showing printing progress. As of 4.1 this only has effect on Mac OS X where, by default, a status dialog is shown. |
| QPrintEngine::PPK_CustomBase | 0xff00 | Basis for extension. |
Destroys the print engine.
Instructs the print engine to abort the printing process. Returns true if successful; otherwise returns false.
Returns the metric for the given id.
Instructs the print engine to start a new page. Returns true if the printer was able to create the new page; otherwise returns false.
Returns the current state of the printer being used by the print engine.
Returns the print engine's property specified by key.
See also setProperty().
Sets the print engine's property specified by key to the given value.
See also property().
