/// <picture><source srcset="combo-row-dark.png" media="(prefers-color-scheme: dark)"><img src="combo-row.png" alt="combo-row"></picture>
/// 
/// The `AdwComboRow` widget allows the user to choose from a list of valid
/// choices. The row displays the selected choice. When activated, the row
/// displays a popover which allows the user to make a new choice.
/// 
/// Example of an `AdwComboRow` UI definition:
/// ```xml
/// <object class="AdwComboRow"><property name="title" translatable="yes">Combo Row</property><property name="model"><object class="GtkStringList"><items><item translatable="yes">Foo</item><item translatable="yes">Bar</item><item translatable="yes">Baz</item></items></object></property></object>
/// ```
/// 
/// The [property@ComboRow:selected] and [property@ComboRow:selected-item]
/// properties can be used to keep track of the selected item and react to their
/// changes.
/// 
/// `AdwComboRow` mirrors [class@Gtk.DropDown], see that widget for details.
/// 
/// `AdwComboRow` is [property@Gtk.ListBoxRow:activatable] if a model is set.
/// 
/// ## CSS nodes
/// 
/// `AdwComboRow` has a main CSS node with name `row` and the `.combo` style
/// class.
/// 
/// Its popover has the node named `popover` with the `.menu` style class, it
/// contains a [class@Gtk.ScrolledWindow], which in turn contains a
/// [class@Gtk.ListView], both are accessible via their regular nodes.
/// 
/// ## Accessibility
/// 
/// `AdwComboRow` uses the `GTK_ACCESSIBLE_ROLE_COMBO_BOX` role.
