| 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. |

| 777 | Called by the framework to obtain information from the application about minimum and maximum page values that |

| 897 | print job (regardless of how many copies are being printed). |
| 898 | |
| 899 | \membersection{wxPrintout::OnEndPrinting}\label{wxprintoutonendprinting} |
| 900 | |
| 901 | \func{void}{OnEndPrinting}{\void} |
| 902 | |
| 903 | Called by the framework at the end of printing. OnEndPrinting |
| 904 | is called once for every print job (regardless of how many copies are being printed). |
| 905 | |
| 906 | \membersection{wxPrintout::OnPreparePrinting}\label{wxprintoutonprepareprinting} |
| 907 | |
| 908 | \func{void}{OnPreparePrinting}{\void} |
| 909 | |
| 910 | Called once by the framework before any other demands are made of the |
| 911 | wxPrintout object. This gives the object an opportunity to calculate the |
| 912 | number of pages in the document, for example. |
| 913 | |
| 914 | \membersection{wxPrintout::OnPrintPage}\label{wxprintoutonprintpage} |
| 915 | |
| 916 | \func{bool}{OnPrintPage}{\param{int}{ pageNum}} |
| 917 | |
| 918 | Called by the framework when a page should be printed. Returning FALSE cancels |
| 919 | the print job. The application can use wxPrintout::GetDC to obtain a device |
| 920 | context to draw on. |
| 921 | |
| 922 | \section{\class{wxPrintPreview}}\label{wxprintpreview} |
| 923 | |
| 924 | Objects of this class manage the print preview process. The object is passed |
| 925 | a wxPrintout object, and the wxPrintPreview object itself is passed to |
| 926 | a wxPreviewFrame object. Previewing is started by initializing and showing |
| 927 | the preview frame. Unlike wxPrinter::Print, flow of control returns to the application |
| 928 | immediately after the frame is shown. |

| 949 | \func{}{wxPrintPreview}{\param{wxPrintout* }{printout}, \param{wxPrintout* }{printoutForPrinting}, |
| 950 | \param{wxPrintData* }{data=NULL}} |
| 951 | |
| 952 | Constructor. Pass a printout object, an optional printout object to be |
| 953 | used for actual printing, and the address of an optional |
| 954 | block of printer data, which will be copied to the print preview object's |
| 955 | print data. |
| 956 | |
| 957 | If {\it printoutForPrinting} is non-NULL, a {\bf Print...} button will be placed on the |
| 958 | preview frame so that the user can print directly from the preview interface. |
| 959 | |
| 960 | Do not explicitly delete the printout objects once this destructor has been |
| 961 | called, since they will be deleted in the wxPrintPreview constructor. |
| 962 | The same does not apply to the {\it data} argument. |
| 963 | |
| 964 | Test the Ok member to check whether the wxPrintPreview object was created correctly. |
| 965 | Ok could return FALSE if there was a problem initializing the printer device context |
| 966 | (current printer not set, for example). |
| 967 | |
| 968 | \membersection{wxPrintPreview::\destruct{wxPrintPreview}} |

| 973 | in your application. |
| 974 | |

| 1032 | \membersection{wxPrintPreview::Ok}\label{wxprintpreviewok} |
| 1033 | |
| 1034 | \func{bool}{Ok}{\void} |
| 1035 | |
| 1036 | Returns TRUE if the wxPrintPreview is valid, FALSE otherwise. It could return FALSE if there was a |
| 1037 | problem initializing the printer device context (current printer not set, for example). |
| 1038 | |
| 1039 | \membersection{wxPrintPreview::PaintPage}\label{wxprintpreviewpaintpage} |
| 1040 | |
| 1041 | \func{bool}{PaintPage}{\param{wxWindow* }{window}} |
| 1042 | |
| 1043 | This refreshes the preview window with the preview image. |
| 1044 | It must be called from the preview window's OnPaint member. |
| 1045 | |
| 1046 | The implementation simply blits the preview bitmap onto |
| 1047 | the canvas, creating a new preview bitmap if none exists. |
