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 notebook 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_popup_enable(), gtk_notebook_popup_disable()) GtkNotebook as GtkBuildable The GtkNoteboopk implementation of the GtkBuildable interface supports placing children into tabs by specifying "tab" as the "type" attribute of a <child> element. Note that the content of the tab must be created before the tab can be filled. A tab child can be specified without specifying a <child> type attribute. To add a child widget in the notebooks action area, specify "action-start" or "action-end" as the "type" attribute of the <child> element.
