1. printJobSetPageRanges :: (HasCallStack, MonadIO m, IsPrintJob a) => a -> [PageRange] -> m ()

   gi-gtk4	GI.Gtk.Objects.PrintJob

   Sets the page ranges for this job.

2. printJobSetPageSet :: (HasCallStack, MonadIO m, IsPrintJob a) => a -> PageSet -> m ()

   gi-gtk4	GI.Gtk.Objects.PrintJob

   Sets the GtkPageSet setting for this job.

3. printJobSetPages :: (HasCallStack, MonadIO m, IsPrintJob a) => a -> PrintPages -> m ()

   gi-gtk4	GI.Gtk.Objects.PrintJob

   Sets the GtkPrintPages setting for this job.

4. type PrintOperationDrawPageCallback = PrintContext -> Int32 -> IO ()

   gi-gtk4	GI.Gtk.Objects.PrintOperation

   Emitted for every page that is printed. The signal handler must render the pageNr's page onto the cairo context obtained from context using printContextGetCairoContext.

   c code

   static void
   draw_page (GtkPrintOperation *operation,
   GtkPrintContext   *context,
   int                page_nr,
   gpointer           user_data)
   {
   cairo_t *cr;
   PangoLayout *layout;
   double width, text_height;
   int layout_height;
   PangoFontDescription *desc;
   
   cr = gtk_print_context_get_cairo_context (context);
   width = gtk_print_context_get_width (context);
   
   cairo_rectangle (cr, 0, 0, width, HEADER_HEIGHT);
   
   cairo_set_source_rgb (cr, 0.8, 0.8, 0.8);
   cairo_fill (cr);
   
   layout = gtk_print_context_create_pango_layout (context);
   
   desc = pango_font_description_from_string ("sans 14");
   pango_layout_set_font_description (layout, desc);
   pango_font_description_free (desc);
   
   pango_layout_set_text (layout, "some text", -1);
   pango_layout_set_width (layout, width * PANGO_SCALE);
   pango_layout_set_alignment (layout, PANGO_ALIGN_CENTER);
   
   pango_layout_get_size (layout, NULL, &layout_height);
   text_height = (double)layout_height / PANGO_SCALE;
   
   cairo_move_to (cr, width / 2,  (HEADER_HEIGHT - text_height) / 2);
   pango_cairo_show_layout (cr, layout);
   
   g_object_unref (layout);
   }
   

   Use printOperationSetUseFullPage and printOperationSetUnit before starting the print operation to set up the transformation of the cairo context according to your needs.

5. type PrintOperationRequestPageSetupCallback = PrintContext -> Int32 -> PageSetup -> IO ()

   gi-gtk4	GI.Gtk.Objects.PrintOperation

   Emitted once for every page that is printed. This gives the application a chance to modify the page setup. Any changes done to setup will be in force only for printing this page.

6. afterPrintOperationDrawPage :: (IsPrintOperation a, MonadIO m) => a -> ((?self :: a) => PrintOperationDrawPageCallback) -> m SignalHandlerId

   gi-gtk4	GI.Gtk.Objects.PrintOperation

   Connect a signal handler for the drawPage signal, to be run after the default handler. When overloading is enabled, this is equivalent to

   after printOperation #drawPage callback
   

   By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

7. afterPrintOperationRequestPageSetup :: (IsPrintOperation a, MonadIO m) => a -> ((?self :: a) => PrintOperationRequestPageSetupCallback) -> m SignalHandlerId

   gi-gtk4	GI.Gtk.Objects.PrintOperation

   Connect a signal handler for the requestPageSetup signal, to be run after the default handler. When overloading is enabled, this is equivalent to

   after printOperation #requestPageSetup callback
   

   By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

8. clearPrintOperationDefaultPageSetup :: (MonadIO m, IsPrintOperation o) => o -> m ()

   gi-gtk4	GI.Gtk.Objects.PrintOperation

   Set the value of the “default-page-setup” property to Nothing. When overloading is enabled, this is equivalent to

   clear #defaultPageSetup
   

9. constructPrintOperationCurrentPage :: (IsPrintOperation o, MonadIO m) => Int32 -> m (GValueConstruct o)

   gi-gtk4	GI.Gtk.Objects.PrintOperation

   Construct a GValueConstruct with valid value for the “current-page” property. This is rarely needed directly, but it is used by new.

10. constructPrintOperationDefaultPageSetup :: (IsPrintOperation o, MonadIO m, IsPageSetup a) => a -> m (GValueConstruct o)

    gi-gtk4	GI.Gtk.Objects.PrintOperation

    Construct a GValueConstruct with valid value for the “default-page-setup” property. This is rarely needed directly, but it is used by new.
