Gtk.Buildable – gtk4 – Vala Binding Reference

Description:

[ CCode ( type_id = "gtk_buildable_get_type ()" ) ]
public interface Buildable : Object

Allows objects to extend and customize deserialization from ui files.

The `GtkBuildable` interface includes methods for setting names and properties of objects, parsing custom tags and constructing child objects.

It 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.
