   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.

 751
 752 Called by the framework to obtain information from the application about minimum and maximum page values that
 753 the user can select, and the required page range to be printed. By default this
 754 returns 1, 32000 for the page minimum and maximum values, and 1, 1 for the required page range.
 755
 756 If {\it minPage} is zero, the page number controls in the print dialog will be disabled.

 774
 775 Returns the size of the printer page in pixels. These may not be the
 776 same as the values returned from \helpref{wxDC::GetSize}{wxdcgetsize} if
 777 the printout is being used for previewing, since in this case, a
 778 memory device context is used, using a bitmap size reflecting the current
 779 preview zoom. The application must take this discrepancy into account if
 780 previewing is to be supported.

 785
 786 \func{void}{GetPPIPrinter}{\param{int *}{w}, \param{int *}{h}}
 787
 788 Returns the number of pixels per logical inch of the printer device context.
 789 Dividing the printer PPI by the screen PPI can give a suitable scaling
 790 factor for drawing text onto the printer. Remember to multiply
 791 this by a scaling factor to take the preview DC size into account.

 808 \func{bool}{HasPage}{\param{int}{ pageNum}}
 809
 810 Should be overridden to return TRUE if the document has this page, or FALSE
 811 if not. Returning FALSE signifies the end of the document. By default,
 812 HasPage behaves as if the document has only one page.
 813
 814 \membersection{wxPrintout::IsPreview}\label{wxprintoutispreview}
 815
 816 \func{bool}{IsPreview}{\void}
 817

 823
 824 Called by the framework at the start of document printing. Return FALSE from
 825 this function cancels the print job. OnBeginDocument is called once for every
 826 copy printed.
 827
 828 The base wxPrintout::OnBeginDocument {\it must} be called (and the return value
 829 checked) from within the overridden function, since it calls wxDC::StartDoc.
 830
 831 \pythonnote{If this method is overridden in a Python class then the

 864 wxPrintout object. This gives the object an opportunity to calculate the
 865 number of pages in the document, for example.
 866
 867 \membersection{wxPrintout::OnPrintPage}\label{wxprintoutonprintpage}
 868
 869 \func{bool}{OnPrintPage}{\param{int}{ pageNum}}
 870
 871 Called by the framework when a page should be printed. Returning FALSE cancels
 872 the print job. The application can use wxPrintout::GetDC to obtain a device
 873 context to draw on.
 874
 875 \section{\class{wxPrintPreview}}\label{wxprintpreview}
 876
 877 Objects of this class manage the print preview process. The object is passed
 878 a wxPrintout object, and the wxPrintPreview object itself is passed to
 879 a wxPreviewFrame object. Previewing is started by initializing and showing
 880 the preview frame. Unlike wxPrinter::Print, flow of control returns to the application
 881 immediately after the frame is shown.

 904
 905 Constructor. Pass a printout object, an optional printout object to be
 906 used for actual printing, and the address of an optional
 907 block of printer data, which will be copied to the print preview object's
 908 print data.
 909
 910 If {\it printoutForPrinting} is non-NULL, a {\bf Print...} button will be placed on the
 911 preview frame so that the user can print directly from the preview interface.

 913 Do not explicitly delete the printout objects once this destructor has been
 914 called, since they will be deleted in the wxPrintPreview constructor.
 915 The same does not apply to the {\it data} argument.
