   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.

 538 be achieved through using of lower functions and classes, but
 539 this and associated classes provide a more convenient and general
 540 method of printing.

 598 the printing of a document, and whether the print dialog should be invoked first.
 599
 600 Print could return FALSE if there was a problem initializing the printer device context

 654 is the recommended way to construct a wxPrinterDC.

 658
 659 Constructor. With empty strings for the first three arguments, the default printer dialog is
 660 displayed. {\it device} indicates the type of printer and {\it output}
 661 is an optional file for printing to. The {\it driver} parameter is
 662 currently unused.  Use the {\it Ok} member to test whether the

 668
 669 This class encapsulates the functionality of printing out an
 670 application document. A new class must be derived and members
 671 overridden to respond to calls such as OnPrintPage and HasPage.
 672 Instances of this class are passed to wxPrinter::Print or a

 702 \membersection{wxPrintout::GetDC}\label{wxprintoutgetdc}
 703
 704 \func{wxDC *}{GetDC}{\void}
 705
 706 Returns the device context associated with the printout (given to the printout at start of
 707 printing or previewing). This will be a wxPrinterDC if printing under Windows,
 708 a wxPostScriptDC if printing on other platforms, and a wxMemoryDC if previewing.

 711
 712 \func{void}{GetPageInfo}{\param{int *}{minPage}, \param{int *}{maxPage}, \param{int *}{pageFrom}, \param{int *}{pageTo}}
 713
 714 Called by the framework to obtain information from the application about minimum and maximum page values that
 715 the user can select, and the required page range to be printed. By default this
 716 returns 1, 32000 for the page minimum and maximum values, and 1, 1 for the required page range.
 717
 718 If {\it minPage} is zero, the page number controls in the print dialog will be disabled.
 719
 720 \membersection{wxPrintout::GetPageSizeMM}\label{wxprintoutgetpagesizemm}
 721
 722 \func{void}{GetPageSizeMM}{\param{int *}{w}, \param{int *}{h}}
 723

 726 \membersection{wxPrintout::GetPageSizePixels}\label{wxprintoutgetpagesizepixels}
 727
 728 \func{void}{GetPageSizePixels}{\param{int *}{w}, \param{int *}{h}}
 729
 730 Returns the size of the printer page in pixels. These may not be the
 731 same as the values returned from \helpref{wxDC::GetSize}{wxdcgetsize} if
 732 the printout is being used for previewing, since in this case, a
 733 memory device context is used, using a bitmap size reflecting the current
 734 preview zoom. The application must take this discrepancy into account if
 735 previewing is to be supported.
 736
 737 \membersection{wxPrintout::GetPPIPrinter}\label{wxprintoutgetppiprinter}
 738
 739 \func{void}{GetPPIPrinter}{\param{int *}{w}, \param{int *}{h}}
 740
 741 Returns the number of pixels per logical inch of the printer device context.
 742 Dividing the printer PPI by the screen PPI can give a suitable scaling
 743 factor for drawing text onto the printer. Remember to multiply
 744 this by a scaling factor to take the preview DC size into account.
 745
 746 \membersection{wxPrintout::GetPPIScreen}\label{wxprintoutgetppiscreen}
 747
 748 \func{void}{GetPPIScreen}{\param{int *}{w}, \param{int *}{h}}
 749
 750 Returns the number of pixels per logical inch of the screen device context.
 751 Dividing the printer PPI by the screen PPI can give a suitable scaling
 752 factor for drawing text onto the printer. Remember to multiply
 753 this by a scaling factor to take the preview DC size into account.
 754
 755 \membersection{wxPrintout::HasPage}\label{wxprintouthaspage}
 756
 757 \func{bool}{HasPage}{\param{int}{ pageNum}}
 758
 759 Should be overriden to return TRUE if the document has this page, or FALSE
 760 if not. Returning FALSE signifies the end of the document. By default,
 761 HasPage behaves as if the document has only one page.
 762
 763 \membersection{wxPrintout::IsPreview}\label{wxprintoutispreview}
 764
 765 \func{bool}{IsPreview}{\void}
 766
 767 Returns TRUE if the printout is currently being used for previewing.
 768
 769 \membersection{wxPrintout::OnBeginDocument}\label{wxprintoutonbegindocument}
 770
 771 \func{bool}{OnBeginDocument}{\param{int}{ startPage}, \param{int}{ endPage}}
 772
 773 Called by the framework at the start of document printing. Return FALSE from
 774 this function cancels the print job. OnBeginDocument is called once for every
 775 copy printed.
 776
 777 The base wxPrintout::OnBeginDocument {\it must} be called (and the return value
 778 checked) from within the overriden function, since it calls wxDC::StartDoc.
 779
 780 \membersection{wxPrintout::OnEndDocument}\label{wxprintoutonenddocument}
 781
 782 \func{void}{OnEndDocument}{\void}
 783
 784 Called by the framework at the end of document printing. OnEndDocument
 785 is called once for every copy printed.
 786
 787 The base wxPrintout::OnEndDocument {\it must} be called
 788 from within the overriden function, since it calls wxDC::EndDoc.
 789
 790 \membersection{wxPrintout::OnBeginPrinting}\label{wxprintoutonbeginprinting}
 791
 792 \func{void}{OnBeginPrinting}{\void}

 795 print job (regardless of how many copies are being printed).
 796
 797 \membersection{wxPrintout::OnEndPrinting}\label{wxprintoutonendprinting}
 798
 799 \func{void}{OnEndPrinting}{\void}

 802 is called once for every print job (regardless of how many copies are being printed).
 803
 804 \membersection{wxPrintout::OnPreparePrinting}\label{wxprintoutonprepareprinting}
 805
 806 \func{void}{OnPreparePrinting}{\void}
 807
 808 Called once by the framework before any other demands are made of the
 809 wxPrintout object. This gives the object an opportunity to calculate the
 810 number of pages in the document, for example.
 811
 812 \membersection{wxPrintout::OnPrintPage}\label{wxprintoutonprintpage}
 813
 814 \func{bool}{OnPrintPage}{\param{int}{ pageNum}}
 815
 816 Called by the framework when a page should be printed. Returning FALSE cancels
 817 the print job. The application can use wxPrintout::GetDC to obtain a device
 818 context to draw on.
 819
 820 \section{\class{wxPrintPreview}}\label{wxprintpreview}
 821
 822 \overview{Printing framework overview}{printingoverview}
 823
 824 Objects of this class manage the print preview process. The object is passed
 825 a wxPrintout object, and the wxPrintPreview object itself is passed to
 826 a wxPreviewFrame object. Previewing is started by initializing and showing
 827 the preview frame. Unlike wxPrinter::Print, flow of control returns to the application
 828 immediately after the frame is shown.

 851
 852 Constructor. Pass a printout object, an optional printout object to be
 853 used for actual printing, and the address of an optional
 854 block of printer data, which will be copied to the print preview object's
 855 print data.
 856
 857 If {\it printoutForPrinting} is non-NULL, a {\bf Print...} button will be placed on the
 858 preview frame so that the user can print directly from the preview interface.
 859
 860 Do not explicitly delete the printout objects once this destructor has been
 861 called, since they will be deleted in the wxPrintPreview constructor.
 862 The same does not apply to the {\it data} argument.
 863
 864 Test the Ok member to check whether the wxPrintPreview object was created correctly.
 865 Ok could return FALSE if there was a problem initializing the printer device context
 866 (current printer not set, for example).
 867
 868 \membersection{wxPrintPreview::\destruct{wxPrintPreview}}

 870 \func{}{\destruct{wxPrinter}}{\void}

 873 in your application.
