Description

A container with just one child

Synopsis

Detail

The Bin 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 Bin, including Window, Button, Frame, HandleBox, and ScrolledWindow.
