  1. newtype NotebookPageAccessible

    gi-gtk3 GI.Gtk.Objects.NotebookPageAccessible

    Memory-managed wrapper type.

  2. NotebookPageAccessible :: ManagedPtr NotebookPageAccessible -> NotebookPageAccessible

    gi-gtk3 GI.Gtk.Objects.NotebookPageAccessible

    No documentation available.

  3. notebookPageAccessibleInvalidate :: (HasCallStack, MonadIO m, IsNotebookPageAccessible a) => a -> m ()

    gi-gtk3 GI.Gtk.Objects.NotebookPageAccessible

    No description available in the introspection data.

  4. notebookPageAccessibleNew :: (HasCallStack, MonadIO m, IsNotebookAccessible a, IsWidget b) => a -> b -> m NotebookPageAccessible

    gi-gtk3 GI.Gtk.Objects.NotebookPageAccessible

    No description available in the introspection data.

  5. toNotebookPageAccessible :: (MonadIO m, IsNotebookPageAccessible o) => o -> m NotebookPageAccessible

    gi-gtk3 GI.Gtk.Objects.NotebookPageAccessible

    Cast to NotebookPageAccessible, for types for which this is known to be safe. For general casts, use castTo.

  6. class (GObject o, IsDescendantOf PageSetup o) => IsPageSetup o

    gi-gtk3 GI.Gtk.Objects.PageSetup

    Type class for types which can be safely cast to PageSetup, for instance with toPageSetup.

  7. toPageSetup :: (MonadIO m, IsPageSetup o) => o -> m PageSetup

    gi-gtk3 GI.Gtk.Objects.PageSetup

    Cast to PageSetup, for types for which this is known to be safe. For general casts, use castTo.

  8. printContextGetPageSetup :: (HasCallStack, MonadIO m, IsPrintContext a) => a -> m PageSetup

    gi-gtk3 GI.Gtk.Objects.PrintContext

    Obtains the PageSetup that determines the page dimensions of the PrintContext. Since: 2.10

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

    gi-gtk3 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,
gint               page_nr,
gpointer           user_data)
{
cairo_t *cr;
PangoLayout *layout;
gdouble width, text_height;
gint 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 = (gdouble)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. Since: 2.10

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

    gi-gtk3 GI.Gtk.Objects.PrintOperation

    Emitted once for every page that is printed, to give the application a chance to modify the page setup. Any changes done to setup will be in force only for printing this page. Since: 2.10
