## Description

WebKitBackForwardList maintains a list of visited pages used to navigate to recent pages. Items are inserted in the list in the order they are visited.

WebKitBackForwardList also maintains the notion of the current item (which is always at index 0), the preceding item (which is at index -1), and the following item (which is at index 1). Methods `webkit_web_view_go_back()` and `webkit_web_view_go_forward()` move the current item backward or forward by one. Method `webkit_web_view_go_to_back_forward_list_item()` sets the current item to the specified item. All other methods returning WebKitBackForwardListItems do not change the value of the current item, they just return the requested item or items.

## Signal Details

### The `"changed"` signal

    void                user_function                      (WebKitBackForwardList     *back_forward_list,
                                                            WebKitBackForwardListItem *item_added,
                                                            gpointer                   items_removed,
                                                            gpointer                   user_data)              : Run Last

This signal is emitted when `back_forward_list` changes. This happens when the current item is updated, a new item is added or one or more items are removed. Note that both `item_added` and `items_removed` can `NULL` when only the current item is updated. Items are only removed when the list is cleared or the maximum items limit is reached.

`back_forward_list` : | the WebKitBackForwardList on which the signal was emitted
`item_added` : | the WebKitBackForwardListItem added or `NULL`. [allow-none]
`items_removed` : | a GList of WebKitBackForwardListItems
`user_data` : | user data set when the signal handler was connected.
