- * @Short_description: A container with just one child
- * @Title: GtkBin
- *
- * The #GtkBin widget is a container with just one child.
- * It is not very useful itself, but it is useful for deriving subclasses,
- * since it provides common code needed for handling a single child widget.
- *
- * Many GTK+ widgets are subclasses of #GtkBin, including #GtkWindow,
- * #GtkButton, #GtkFrame or #GtkScrolledWindow.
