--  <description>
--  The Gtk.Notebook.Gtk_Notebook widget is a Gtk.Container.Gtk_Container
--  whose children are pages that can be switched between using tab labels
--  along one edge.
--
--  There are many configuration options for GtkNotebook. Among other things,
--  you can choose on which edge the tabs appear (see
--  Gtk.Notebook.Set_Tab_Pos), whether, if there are too many tabs to fit the
--  notebook should be made bigger or scrolling arrows added (see
--  Gtk.Notebook.Set_Scrollable), and whether there will be a popup menu
--  allowing the users to switch pages. (see Gtk.Notebook.Popup_Enable,
--  Gtk.Notebook.Popup_Disable)
--
--  # GtkNotebook as GtkBuildable
--
--  The GtkNotebook implementation of the Gtk.Buildable.Gtk_Buildable
--  interface supports placing children into tabs by specifying "tab" as the
--  "type" attribute of a <child> element. Note that the content of the tab
--  must be created before the tab can be filled. A tab child can be specified
--  without specifying a <child> type attribute.
--
--  To add a child widget in the notebooks action area, specify "action-start"
--  or "action-end" as the "type" attribute of the <child> element.
--
--  An example of a UI definition fragment with GtkNotebook: |[ <object
--  class="GtkNotebook"> <child> <object class="GtkLabel"
--  id="notebook-content"> <property name="label">Content</property> </object>
--  </child> <child type="tab"> <object class="GtkLabel" id="notebook-tab">
--  <property name="label">Tab</property> </object> </child> </object> ]|
