+ * @short_description: A dynamic tabbed container
+ * @title: AdwTabView
+ * @See_also: #AdwTabBar
+ *
+ * #AdwTabView is a container which shows one child at a time. While it provides
+ * keyboard shortcuts for switching between pages, it does not provide a visible
+ * tab bar and relies on external widgets for that, such as #AdwTabBar.
+ *
+ * #AdwTabView maintains a #AdwTabPage object for each page,which holds
+ * additional per-page properties. You can obtain the #AdwTabPage for a page
+ * with adw_tab_view_get_page(), and as return value for adw_tab_view_append()
+ * and other functions for adding children.
+ *
+ * #AdwTabView only aims to be useful for dynamic tabs in multi-window
+ * document-based applications, such as web browsers, file managers, text
+ * editors or terminals. It does not aim to replace #GtkNotebook for use cases
+ * such as tabbed dialogs.
+ *
+ * As such, it does not support disabling page reordering or detaching, or
+ * adding children via #GtkBuilder.
+ *
+ * # CSS nodes
+ *
+ * #AdwTabView has a main CSS node with the name tabview.
+ *
+ * It contains the subnode overlay, which contains subnodes stack and widget.
+ * The stack subnode contains the added pages.
+ *
+ * |[<!-- language="plain" -->
+ * tabview
+ * ├── stack
+ * │ ╰── [ Children ]
+ * ╰── widget
