.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
.
