GtkPopoverMenu is a subclass of #GtkPopover that treats its children like menus and allows switching between them. It is meant to be used primarily together with #GtkModelButton, but any widget can be used, such as #GtkSpinButton or #GtkScale. In this respect, GtkPopoverMenu is more flexible than popovers that are created from a #GMenuModel with gtk_popover_new_from_model().
