/// 
/// `AdwEntryRow` has a title that doubles as placeholder text. It shows an icon
/// indicating that it's editable and can receive additional widgets before or
/// after the editable part.
/// 
/// If [property@EntryRow:show-apply-button] is set to `TRUE`, `AdwEntryRow` can
/// show an apply button when editing its contents. This can be useful if
/// changing its contents can result in an expensive operation, such as network
/// activity.

/// [iface@Gtk.Editable] API.

/// ## AdwEntryRow as GtkBuildable
/// 
/// The `AdwEntryRow` 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
/// 
/// `AdwEntryRow` has a single CSS node with name `row` and the `.entry` style
/// class.
