Implemented Interfaces

GtkBin implements AtkImplementorIface and GtkBuildable.

Includes

#include <gtk/gtk.h>

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.

Functions

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.

Parameters

bin

a GtkBin

Returns

the child of bin , or NULL if it does not have a child.

[transfer none][nullable]

Types and Values

struct GtkBin

struct GtkBin;

struct GtkBinClass

struct GtkBinClass {
  GtkContainerClass parent_class;
};
