is an abstract base class defining a widget that is a container with just
one child. It is useful for deriving subclasses, since it provides the
common code needed for handling a single child widget. Many PyGTK widgets
are subclasses of <a href="class-gtkbin.html" title="gtk.Bin"><tt class="classname">gtk.Bin</tt></a>, including
