-- <description>
-- Gtk.Builder - Build an interface from an XML UI definition as produced by
-- the Glade-3 GUI builder.
--
-- Note that GtkAda provides a higher-level API for using the GUI builder,
-- in Gtkada.Builder.
--
-- A Gtk_Builder is an auxiliary object that reads textual descriptions of a
-- user interface and instantiates the described objects. To pass a
-- description to a Gtk_Builder, call Add_From_File or Add_From_String.
-- These subprograms can be called multiple times; the builder merges the
-- content of all descriptions.
--
-- A Gtk_Builder holds a reference to all objects that it has constructed and
-- drops these references when it is finalized. This finalization can cause
-- the destruction of non-widget objects or widgets which are not contained
-- in a toplevel window. For toplevel windows constructed by a builder, it is
-- the responsibility of the user to call Gtk.Widget.Destroy to get rid of
-- them and all the widgets they contain.
--
-- The subprograms Get_Object and Get_Widget can be used to access the widgets
-- in the interface by the names assigned to them inside the UI description.
-- Toplevel windows returned by this subprogram will stay around until the
-- user explicitly destroys them with Gtk.Widget.Destroy.
-- Other widgets will either be part of a larger hierarchy constructed by
-- the builder (in which case you should not have to worry about their
-- lifecycle), or without a parent, in which case they have to be added
-- to some container to make use of them. Non-widget objects need to be
-- reffed with Glib.Object.Ref to keep them beyond the lifespan of the
-- builder.
--
-- The subprogram Connect_Signals_Full can be used to connect handlers to the
-- named signals in the description.

-- Signal_Name: The name of the signal
