/**
 * AdwActionRow:
 *
 * A [class@Gtk.ListBoxRow] used to present actions.
 *
 * <picture>
 *   <source srcset="action-row-dark.png" media="(prefers-color-scheme: dark)">
 *   <img src="action-row.png" alt="action-row">
 * </picture>
 *
 * The `AdwActionRow` widget can have a title, a subtitle and an icon. The row
 * can receive additional widgets at its end, or prefix widgets at its start.
 *
 * It is convenient to present a preference and its related actions.
 *
 * `AdwActionRow` is unactivatable by default, giving it an activatable widget
 * will automatically make it activatable, but unsetting it won't change the
 * row's activatability.
 *
 * ## AdwActionRow as GtkBuildable
 *
 * The `AdwActionRow` implementation of the [iface@Gtk.Buildable] interface
 * supports adding a child at its end by specifying “suffix” or omitting the
 * “type” attribute of a <child> element.
 *
 * It also supports adding a child as a prefix widget by specifying “prefix” as
 * the “type” attribute of a <child> element.
 *
 * ## CSS nodes
 *
 * `AdwActionRow` has a main CSS node with name `row`.
 *
 * It contains the subnode `box.header` for its main horizontal box, and
 * `box.title` for the vertical box containing the title and subtitle labels.
 *
 * It contains subnodes `label.title` and `label.subtitle` representing
 * respectively the title label and subtitle label.
