public interface Buildable : Object
`GtkBuildable` allows objects to extend and customize their deserialization from ui files.
The interface includes methods for setting names and properties of objects, parsing custom tags and constructing child objects.
The `GtkBuildable` interface is implemented by all widgets and many of the non-widget objects that are provided by GTK. The main user of this interface is [class@Gtk.Builder]. There should be very little need for applications to call any of these functions directly.
An object only needs to implement this interface if it needs to extend the `GtkBuilder` XML format or run any extra routines at deserialization time.
