Struct webkit6::BackForwardList

source ·
pub struct BackForwardList { /* private fields */ }
Expand description

List of visited pages.

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.

§Signals

§changed

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 None when only the current item is updated. Items are only removed when the list is cleared or the maximum items limit is reached.

GLib type: GObject with reference counted clone semantics.
