      Object onCreateCustomWidget()
      Emitted when displaying the print dialog.

      If you return a widget in a handler for this signal it will be
      added to a custom tab in the print dialog. You typically return a
      container widget with multiple widgets in it.

      The print dialog owns the returned widget, and its lifetime is not
      controlled by the application. However, the widget is guaranteed
      to stay around until the [signal@Gtk.PrintOperation::custom-widget-apply]
      signal is emitted on the operation. Then you can read out any
      information you need from the widgets.
      Returns:
      A custom widget that gets embedded in the print dialog
