/**
 * A GtkListBox is a vertical container that contains GtkListBoxRow
 * children. These rows can by dynamically sorted and filtered, and
 * headers can be added dynamically depending on the row content.
 * It also allows keyboard and mouse navigation and selection like
 * a typical list.
 * 
 * Using GtkListBox is often an alternative to #GtkTreeView, especially
 * when the list contents has a more complicated layout than what is allowed
 * by a #GtkCellRenderer, or when the contents is interactive (i.e. has a
 * button in it).
 * 
 * Although a #GtkListBox must have only #GtkListBoxRow children you can
 * add any kind of widget to it via gtk_container_add(), and a #GtkListBoxRow
 * widget will automatically be inserted between the list and the widget.
 * 
 * #GtkListBoxRows can be marked as activatable or selectable. If a row
 * is activatable, #GtkListBox::row-activated will be emitted for it when
 * the user tries to activate it. If it is selectable, the row will be marked
 * as selected when the user tries to select it.
 * 
 * The GtkListBox widget was added in GTK+ 3.10.
 * 
 * # CSS nodes
 * 
 * |[<!-- language="plain" -->
 * list
 * ╰── row[.activatable]
 * ]|
 * 
 * GtkListBox uses a single CSS node named list. Each GtkListBoxRow uses
 * a single CSS node named row. The row nodes get the .activatable
 * style class added when appropriate.
