## Description

The GtkNotebook widget is a GtkContainer 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 noteobook 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_enable_popup()`, `gtk_noteobook_disable_popup()`)

## Details

### struct GtkNotebook

    struct GtkNotebook;

### struct GtkNotebookPage

    struct GtkNotebookPage;

The GtkNotebookPage is an opaque implementation detail of GtkNotebook.

### gtk_notebook_new ()

    GtkWidget*  gtk_notebook_new                (void);

Creates a new GtkNotebook widget with no pages.

Returns : | the newly created GtkNotebook

### gtk_notebook_append_page ()

    gint        gtk_notebook_append_page        (GtkNotebook *notebook,
                                                 GtkWidget *child,
                                                 GtkWidget *tab_label);

Appends a page to `notebook`.

`notebook` : | a GtkNotebook
`child` : | the GtkWidget to use as the contents of the page.
`tab_label` : | the GtkWidget to be used as the label for the page, or `NULL` to use the default label, 'page N'.
Returns : | the index (starting from 0) of the appended page in the notebook, or -1 if function fails

### gtk_notebook_append_page_menu ()

    gint        gtk_notebook_append_page_menu   (GtkNotebook *notebook,
                                                 GtkWidget *child,
                                                 GtkWidget *tab_label,
                                                 GtkWidget *menu_label);

Appends a page to `notebook`, specifying the widget to use as the label in the popup menu.

`notebook` : | a GtkNotebook
`child` : | the GtkWidget to use as the contents of the page.
`tab_label` : | the GtkWidget to be used as the label for the page, or `NULL` to use the default label, 'page N'.
`menu_label` : | the widget to use as a label for the page-switch menu, if that is enabled. If `NULL`, and `tab_label` is a GtkLabel or `NULL`, then the menu label will be a newly created label with the same text as `tab_label`; If `tab_label` is not a GtkLabel, `menu_label` must be specified if the page-switch menu is to be used.
Returns : | the index (starting from 0) of the appended page in the notebook, or -1 if function fails

### gtk_notebook_prepend_page ()

    gint        gtk_notebook_prepend_page       (GtkNotebook *notebook,
                                                 GtkWidget *child,
                                                 GtkWidget *tab_label);

Prepends a page to `notebook`.

`notebook` : | a GtkNotebook
`child` : | the GtkWidget to use as the contents of the page.
`tab_label` : | the GtkWidget to be used as the label for the page, or `NULL` to use the default label, 'page N'.
Returns : | the index (starting from 0) of the prepended page in the notebook, or -1 if function fails

### gtk_notebook_prepend_page_menu ()

    gint        gtk_notebook_prepend_page_menu  (GtkNotebook *notebook,
                                                 GtkWidget *child,

                                                 GtkWidget *menu_label);

Prepends a page to `notebook`, specifying the widget to use as the label in the popup menu.

`notebook` : | a GtkNotebook
`child` : | the GtkWidget to use as the contents of the page.
`tab_label` : | the GtkWidget to be used as the label for the page, or `NULL` to use the default label, 'page N'.
`menu_label` : | the widget to use as a label for the page-switch menu, if that is enabled. If `NULL`, and `tab_label` is a GtkLabel or `NULL`, then the menu label will be a newly created label with the same text as `tab_label`; If `tab_label` is not a GtkLabel, `menu_label` must be specified if the page-switch menu is to be used.
Returns : | the index (starting from 0) of the prepended page in the notebook, or -1 if function fails

                                                 gint position);

Insert a page into `notebook` at the given position.

`notebook` : | a GtkNotebook
`child` : | the GtkWidget to use as the contents of the page.
