GtkNotebook as GtkBuildable

The GtkNoteboopk implementation of the GtkBuildable 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.

The “create-window” signal

               gint         y,
               gpointer     user_data)

The ::create-window signal is emitted when a detachable tab is dropped on the root window.

A handler for this signal can create a window containing a notebook where the tab will be attached. It is also responsible for moving/resizing the window and adding the necessary properties to the notebook (e.g. the “group” ).

The default handler uses the global window creation hook, if one has been set with gtk_notebook_set_window_creation_hook().
