/**
 * 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 GtkNotebook 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.
 * 
 * An example of a UI definition fragment with GtkNotebook:
 * |[
 * <object class="GtkNotebook">
 * <child>
 * <object class="GtkLabel" id="notebook-content">
 * <property name="label">Content</property>
 * </object>
 * </child>
 * <child type="tab">
 * <object class="GtkLabel" id="notebook-tab">
 * <property name="label">Tab</property>
 * </object>
 * </child>
