## Implemented Interfaces

GtkBin implements AtkImplementorIface and GtkBuildable.

## 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 or GtkScrolledWindow.

## Details

### struct GtkBin

    struct GtkBin;

### gtk_bin_get_child ()

    GtkWidget *         gtk_bin_get_child                   (GtkBin *bin);

Gets the child of the GtkBin, or `NULL` if the bin contains no child widget. The returned widget does not have a reference added, so you do not need to unref it.

`bin` : | a GtkBin
Returns : | pointer to child of the GtkBin. [transfer none]
