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.

810
811 Constructor. Pass a \helpref{wxPrintData}{wxprintdata} object with information
812 necessary for setting up a suitable printer device context. This
813 is the recommended way to construct a wxPrinterDC. Make sure you
814 specify a reference to a \helpref{wxPrintData}{wxprintdata} object,
815 not a pointer - you may not even get a warning if you pass a pointer
816 instead.

820
821 Constructor. With empty strings for the first three arguments, the default printer dialog is
822 displayed. {\it device} indicates the type of printer and {\it output}
823 is an optional file for printing to. The {\it driver} parameter is
824 currently unused. Use the {\it Ok} member to test whether the
825 constructor was successful in creating a usable device context.

831 \func{wxRect}{wxPrinterDC::GetPaperRect}{}
832
833 Return the rectangle in device coordinates that corresponds to the full paper
834 area, including the nonprinting regions of the paper. The point (0,0) in device
835 coordinates is the top left corner of the page rectangle, which is the printable
836 area on MSW and Mac. The coordinates of the top left corner of the paper
837 rectangle will therefore have small negative values, while the bottom right
838 coordinates will be somewhat larger than the values returned by
839 \helpref{wxDC::GetSize}{wxdcgetsize}.
840
841
842 \section{\class{wxPrintout}}\label{wxprintout}
843
844 This class encapsulates the functionality of printing out an application
845 document. A new class must be derived and members overridden to respond to calls
846 such as OnPrintPage and HasPage and to render the print image onto an associated
847 \helpref{wxDC}{wxdc}. Instances of this class are passed to wxPrinter::Print or
848 to a wxPrintPreview object to initiate printing or previewing.
849
850 Your derived wxPrintout is responsible for drawing both the preview image and
851 the printed page. If your windows' drawing routines accept an arbitrary DC as an
852 argument, you can re-use those routines within your wxPrintout subclass to draw
853 the printout image. You may also add additional drawing elements within your
854 wxPrintout subclass, like headers, footers, and/or page numbers. However, the
855 image on the printed page will often differ from the image drawn on the screen,
856 as will the print preview image -- not just in the presence of headers and
857 footers, but typically in scale. A high-resolution printer presents a much
858 larger drawing surface (i.e., a higher-resolution DC); a zoomed-out preview
859 image presents a much smaller drawing surface (lower-resolution DC). By using
860 the routines FitThisSizeToXXX() and/or MapScreenSizeToXXX() within your
861 wxPrintout subclass to set the user scale and origin of the associated DC, you
862 can easily use a single drawing routine to draw on your application's windows,
863 to create the print preview image, and to create the printed paper image, and
864 achieve a common appearance to the preview image and the printed page.

906 Returns the device context associated with the printout (given to the printout at start of
907 printing or previewing). This will be a wxPrinterDC if printing under Windows or Mac,
908 a wxPostScriptDC if printing on other platforms, and a wxMemoryDC if previewing.

914
915 Called by the framework to obtain information from the application about minimum
916 and maximum page values that the user can select, and the required page range to
917 be printed. By default this returns 1, 32000 for the page minimum and maximum
918 values, and 1, 1 for the required page range.
919
920 If {\it minPage} is zero, the page number controls in the print dialog will be disabled.

947
948 Returns the size of the printer page in pixels, called the \em{page rectangle}.
949 The page rectangle has a top left corner at (0,0) and a bottom right corner at
950 (w,h). These values may not be the same as the values returned from
951 \helpref{wxDC::GetSize}{wxdcgetsize}; if the printout is being used for
952 previewing, a memory device context is used, which uses a bitmap size reflecting
953 the current preview zoom. The application must take this discrepancy into
954 account if previewing is to be supported.

963

965
966 Returns the rectangle that corresponds to the entire paper in pixels, called the
967 \em{paper rectangle}. This distinction between paper rectangle and page
968 rectangle reflects the fact that most printers cannot print all the way to the
969 edge of the paper. The page rectangle is a rectangle whose top left corner is at
970 (0,0) and whose width and height are given by
971 \helpref{wxDC::GetPageSizePixels}{wxprintoutgetpagesizepixels}. On MSW and Mac,
972 the page rectangle gives the printable area of the paper, while the paper
973 rectangle represents the entire paper, including non-printable borders. Thus,
974 the rectangle returned by GetPaperRectPixels will have a top left corner whose
975 coordinates are small negative numbers and the bottom right corner will have
976 values somewhat larger than the width and height given by
977 \helpref{wxDC::GetPageSizePixels}{wxprintoutgetpagesizepixels}. On other
978 platforms and for PostScript printing, the paper is treated as if its entire
979 area were printable, so this function will return the same rectangle as the page
980 rectangle.

986
987 Returns the number of pixels per logical inch of the printer device context.
988 Dividing the printer PPI by the screen PPI can give a suitable scaling factor
989 for drawing text onto the printer. Remember to multiply this by a scaling factor
990 to take the preview DC size into account. Or you can just use the
991 FitThisSizeToXXX() and MapScreenSizeToXXX routines below, which do most of the

1042 Set the user scale and device origin of the wxDC associated with this wxPrintout
1043 so that the given image size fits entirely within the paper and the origin is at
1044 the top left corner of the paper. Note that with most printers, the region
1045 around the edges of the paper are not printable so that the edges of the image

1054 so that the given image size fits entirely within the page rectangle and the
1055 origin is at the top left corner of the page rectangle. On MSW and Mac, the page
1056 rectangle is the printable area of the page. On other platforms and PostScript
1057 printing, the page rectangle is the entire paper. Use this if you want your

1066 Set the user scale and device origin of the wxDC associated with this wxPrintout
1067 so that the given image size fits entirely within the page margins set in the
1068 given wxPageSetupDialogData object. This function provides the greatest
1069 consistency across all platforms because it does not depend on having access to
1070 the printable area of the paper. Note that on Mac, the native wxPageSetupDialog
1071 does not let you set the page margins; you'll have to provide your own mechanism,
1072 or you can use the Mac-only class wxMacPageMarginsDialog.

1080 so that the printed page matches the screen size as closely as possible
1081 and the logical origin is in the top left corner of the paper rectangle.
1082 That is,
1083 a 100-pixel object on screen should appear at the same size on the printed page. (It
1084 will, of course, be larger or smaller in the preview image, depending on the zoom
1085 factor.) Use this if you want WYSIWYG behavior, e.g., in a text editor.

1101 This sets the user scale of the wxDC assocated with this wxPrintout to the same
1102 scale as
1103 \helpref{MapScreenSizeToPageMargins}{wxprintoutmapscreensizetopagemargins} but

1110 \func{void}{MapScreenSizeToDevice}{}
1111
1112 Set the user scale and device origin of the wxDC associated with this wxPrintout
1113 so that one screen pixel maps to one device pixel on the DC. That is, the user
1114 scale is set to (1,1) and the device origin is set to (0,0). Use this if you
1115 want to do your own scaling prior to calling wxDC drawing calls, for example, if
1116 your underlying model is floating-point and you want to achieve maximum drawing
1117 precision on high-resolution printers. (Note that while the underlying drawing
1118 model of Mac OS X is floating-point, wxWidgets's drawing model scales from integer
1119 coordinates.) You can use the GetLogicalXXXRect() routines below to obtain the
1120 paper rectangle, page rectangle, or page margins rectangle to perform your own scaling.

1226 \section{\class{wxPrintPreview}}\label{wxprintpreview}
1227
1228 Objects of this class manage the print preview process. The object is passed
1229 a wxPrintout object, and the wxPrintPreview object itself is passed to
1230 a wxPreviewFrame object. Previewing is started by initializing and showing
1231 the preview frame. Unlike wxPrinter::Print, flow of control returns to the application
1232 immediately after the frame is shown.

1260
1261 Constructor. Pass a printout object, an optional printout object to be
1262 used for actual printing, and the address of an optional
1263 block of printer data, which will be copied to the print preview object's
1264 print data.
1265
1266 If {\it printoutForPrinting} is non-NULL, a {\bf Print...} button will be placed on the
1267 preview frame so that the user can print directly from the preview interface.
1268
1269 Do not explicitly delete the printout objects once this destructor has been
1270 called, since they will be deleted in the wxPrintPreview constructor.
1271 The same does not apply to the {\it data} argument.
1272
1273 Test the Ok member to check whether the wxPrintPreview object was created correctly.
1274 Ok could return false if there was a problem initializing the printer device context
1275 (current printer not set, for example).
