PageSetupRef

public struct PageSetupRef : PageSetupProtocol, GWeakCapturing

A GtkPageSetup object stores the page size, orientation and margins. The idea is that you can get one of these from the page setup dialog and then pass it to the GtkPrintOperation when printing. The benefit of splitting this out of the GtkPrintSettings is that these affect the actual layout of the page, and thus need to be set long before user prints.

Margins ##

The margins specified in this object are the “print margins”, i.e. the parts of the page that the printer cannot print on. These are different from the layout margins that a word processor uses; they are typically used to determine the minimal size for the layout margins.

To obtain a GtkPageSetup use gtk_page_setup_new() to get the defaults, or use gtk_print_run_page_setup_dialog() to show the page setup dialog and receive the resulting page setup.

A page setup dialog

(C Language Example):

static GtkPrintSettings *settings = NULL;
static GtkPageSetup *page_setup = NULL;

static void
do_page_setup (void)
{
  GtkPageSetup *new_page_setup;

  if (settings == NULL)
    settings = gtk_print_settings_new ();

  new_page_setup = gtk_print_run_page_setup_dialog (GTK_WINDOW (main_window),
                                                    page_setup, settings);

  if (page_setup)
    g_object_unref (page_setup);

  page_setup = new_page_setup;
}

Printing support was added in GTK+ 2.10.

The PageSetupRef type acts as a lightweight Swift reference to an underlying GtkPageSetup instance. It exposes methods that can operate on this data type through PageSetupProtocol conformance. Use PageSetupRef only as an unowned reference to an existing GtkPageSetup instance.

  • ptr 
    Untyped pointer to the underlying `GtkPageSetup` instance.

    For type-safe access, use the generated, typed pointer page_setup_ptr property instead.
