  /**
   * GtkBuildableIface:
   * @g_iface: the parent class
   * @set_name: Stores the name attribute given in the GtkBuilder UI definition.
   *  #GtkWidget stores the name as object data. Implement this method if your
   *  object has some notion of "name" and it makes sense to map the XML name
   *  attribute to it.
   * @get_name: The getter corresponding to @set_name. Implement this
   *  if you implement @set_name.
   * @add_child: Adds a child. The @type parameter can be used to
   *  differentiate the kind of child. #GtkContainer implements this
   *  to add add a child widget to the container, #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 #GtkWidget: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. #GtkUIManager implements
   *  this to reference to a widget created in a &lt;ui&gt; 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 &lt;child&gt;. To handle an element, the implementation
   *  must fill in the @parser structure and @user_data and return %TRUE.
   *  #GtkWidget implements this to parse keyboard accelerators specified
   *  in &lt;accelerator&gt; elements. #GtkContainer implements it to map
   *  properties defined via &lt;packing&gt; elements to child properties.
   *  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.
   *
   * The GtkBuildableIface interface contains method that are
   * necessary to allow #GtkBuilder to construct an object from
   * a GtkBuilder UI definition.
