Notebook
GtkNotebook is a container whose children are pages switched between using tabs.
There are many configuration options for GtkNotebook. Among other things, you can choose on which edge the tabs appear (see method@Gtk.Notebook.set_tab_pos), whether, if there are too many tabs to fit the notebook should be made bigger or scrolling arrows added (see method@Gtk.Notebook.set_scrollable), and whether there will be a popup menu allowing the users to switch pages. (see method@Gtk.Notebook.popup_enable).
GtkNotebook as GtkBuildable
The GtkNotebook implementation of the GtkBuildable interface supports placing children into tabs by specifying “tab” as the “type” attribute of a

╰── <child>GtkNotebook has a main CSS node with name notebook, a subnode with name header and below that a subnode with name tabs which contains one subnode per tab with name tab.
If action widgets are present, their CSS nodes are placed next to the tabs node. If the notebook is scrollable, CSS nodes with name arrow are placed as first and last child of the tabs node.
The main node gets the .frame style class when the notebook has a border (see method@Gtk.Notebook.set_show_border).
The header node gets one of the style class .top, .bottom, .left or .right, depending on where the tabs are placed. For reorderable pages, the tab node gets the .reorderable-page class.
A tab node gets the .dnd style class while it is moved with drag-and-drop.
The nodes are always arranged from left-to-right, regardless of text direction.

%GTK_ACCESSIBLE_ROLE_GROUP for the notebook widget
