2
3 This class holds a variety of information related to printers and
4 printer device contexts. This class is used to create a wxPrinterDC
5 and a wxPostScriptDC. It is also used as a data member of wxPrintDialogData
6 and wxPageSetupDialogData, as part of the mechanism for transferring data
7 between the print dialogs and the application.

549
550 This class represents the Windows or PostScript printer, and is the vehicle through
551 which printing may be launched by an application. Printing can also
552 be achieved through using of lower functions and classes, but
553 this and associated classes provide a more convenient and general
554 method of printing.

612 the printing of a document, and whether the print dialog should be invoked first.
613
614 Print could return FALSE if there was a problem initializing the printer device context

672
673 Constructor. With empty strings for the first three arguments, the default printer dialog is
674 displayed. {\it device} indicates the type of printer and {\it output}
675 is an optional file for printing to. The {\it driver} parameter is
676 currently unused. Use the {\it Ok} member to test whether the

682
683 This class encapsulates the functionality of printing out an
684 application document. A new class must be derived and members

718 \func{wxDC *}{GetDC}{\void}
719
720 Returns the device context associated with the printout (given to the printout at start of
721 printing or previewing). This will be a wxPrinterDC if printing under Windows,
722 a wxPostScriptDC if printing on other platforms, and a wxMemoryDC if previewing.

725
726 \func{void}{GetPageInfo}{\param{int *}{minPage}, \param{int *}{maxPage}, \param{int *}{pageFrom}, \param{int *}{pageTo}}
727
728 Called by the framework to obtain information from the application about minimum and maximum page values that
729 the user can select, and the required page range to be printed. By default this
730 returns 1, 32000 for the page minimum and maximum values, and 1, 1 for the required page range.
731
732 If {\it minPage} is zero, the page number controls in the print dialog will be disabled.
733

748

750
751 Returns the size of the printer page in pixels. These may not be the
752 same as the values returned from \helpref{wxDC::GetSize}{wxdcgetsize} if
753 the printout is being used for previewing, since in this case, a
754 memory device context is used, using a bitmap size reflecting the current
755 preview zoom. The application must take this discrepancy into account if
756 previewing is to be supported.

763
764 Returns the number of pixels per logical inch of the printer device context.
765 Dividing the printer PPI by the screen PPI can give a suitable scaling
766 factor for drawing text onto the printer. Remember to multiply
767 this by a scaling factor to take the preview DC size into account.

784 \func{bool}{HasPage}{\param{int}{ pageNum}}
785
786 Should be overriden to return TRUE if the document has this page, or FALSE
787 if not. Returning FALSE signifies the end of the document. By default,
788 HasPage behaves as if the document has only one page.
789
790 \membersection{wxPrintout::IsPreview}\label{wxprintoutispreview}
791
792 \func{bool}{IsPreview}{\void}
793

799
800 Called by the framework at the start of document printing. Return FALSE from
801 this function cancels the print job. OnBeginDocument is called once for every
802 copy printed.
803
804 The base wxPrintout::OnBeginDocument {\it must} be called (and the return value
805 checked) from within the overriden function, since it calls wxDC::StartDoc.
806
807 \pythonnote{If this method is overriden in a Python class then the

839 Called once by the framework before any other demands are made of the
840 wxPrintout object. This gives the object an opportunity to calculate the
841 number of pages in the document, for example.
842
843 \membersection{wxPrintout::OnPrintPage}\label{wxprintoutonprintpage}
844
845 \func{bool}{OnPrintPage}{\param{int}{ pageNum}}
846
847 Called by the framework when a page should be printed. Returning FALSE cancels
848 the print job. The application can use wxPrintout::GetDC to obtain a device
849 context to draw on.

851 \section{\class{wxPrintPreview}}\label{wxprintpreview}
852
853 \overview{Printing framework overview}{printingoverview}
854
855 Objects of this class manage the print preview process. The object is passed
856 a wxPrintout object, and the wxPrintPreview object itself is passed to
857 a wxPreviewFrame object. Previewing is started by initializing and showing
858 the preview frame. Unlike wxPrinter::Print, flow of control returns to the application
859 immediately after the frame is shown.

882
883 Constructor. Pass a printout object, an optional printout object to be
884 used for actual printing, and the address of an optional
885 block of printer data, which will be copied to the print preview object's
886 print data.
887
888 If {\it printoutForPrinting} is non-NULL, a {\bf Print...} button will be placed on the
889 preview frame so that the user can print directly from the preview interface.
890
891 Do not explicitly delete the printout objects once this destructor has been
892 called, since they will be deleted in the wxPrintPreview constructor.
893 The same does not apply to the {\it data} argument.
894
895 Test the Ok member to check whether the wxPrintPreview object was created correctly.
896 Ok could return FALSE if there was a problem initializing the printer device context
