## 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.

## Details

### struct GtkBin

    struct GtkBin;

The GtkBin struct contains the following fields. (These fields should be considered read-only. They should never be set by an application.)
