/**
* GtkBuildableIface :
* @ g_iface : the parent class
* @ set_id : Stores the id attribute given in the ` GtkBuilder ` UI definition .
* ` GtkWidget ` stores the name as object data . Implement this method if your
* object has some notion of “ ID ” and it makes sense to map the XML id
* attribute to it .
* @ get_id : The getter corresponding to @ set_id . Implement this
* if you implement @ set_id .
* @ add_child : Adds a child . The @ type parameter can be used to
* differentiate the kind of child . ` GtkWidget ` implements this
* to add event controllers to the widget , ` GtkNotebook ` uses
* the @ type to distinguish between page labels ( of type " page - label " )
* and normal children .
* @ set_buildable_property : Sets a property of a buildable object .
* It is normally not necessary to implement this , g_object_set_property ( )
* is used by default . ` GtkWindow ` implements this to delay showing itself
* ( i . e . setting the [ property @ Gtk . Widget : visible ] property ) until the whole
* interface is created .
* @ construct_child : Constructs a child of a buildable that has been
* specified as “ constructor ” in the UI definition . This can be used to
* reference a widget created in a ` < ui > ` tag which is outside
* of the normal GtkBuilder UI definition hierarchy . A reference to the
* constructed object is returned and becomes owned by the caller .
* @ custom_tag_start : Implement this if the buildable needs to parse
* content below ` < child > ` . To handle an element , the implementation
* must fill in the @ parser and @ user_data and return % TRUE .
* ` GtkWidget ` implements this to parse accessible attributes specified
* in ` < accessibility > ` elements .
* Note that @ user_data must be freed in @ custom_tag_end or @ custom_finished .
* @ custom_tag_end : Called for the end tag of each custom element that is
* handled by the buildable ( see @ custom_tag_start ) .
* @ custom_finished : Called for each custom tag handled by the buildable
* when the builder finishes parsing ( see @ custom_tag_start )
* @ parser_finished : Called when a builder finishes the parsing
* of a UI definition . It is normally not necessary to implement this ,
* unless you need to perform special cleanup actions . ` GtkWindow ` sets
* the ` GtkWidget : visible ` property here .
* @ get_internal_child : Returns an internal child of a buildable .
* ` GtkDialog ` implements this to give access to its @ vbox , making
* it possible to add children to the vbox in a UI definition .
* Implement this if the buildable has internal children that may
* need to be accessed from a UI definition .
*
* Contains methods to let ` GtkBuilder ` construct an object from
* a ` GtkBuilder ` UI definition .
