/**
* SECTION:gtkbuildable
* @Short_description: Interface for objects that can be built by GtkBuilder
* @Title: GtkBuildable
*
* In order to allow construction from a <link linkend="BUILDER-UI">GtkBuilder
* UI description</link>, an object class must implement the
* GtkBuildable interface. The interface includes methods for setting
* names and properties of objects, parsing custom tags, 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 #GtkBuilder, there should be
* very little need for applications to call any
* <function>gtk_buildable_...</function> functions.
