GtkBin implements
AtkImplementorIface and GtkBuildable.Detailed Description
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, GtkHandleBox, and GtkScrolledWindow.References
