Implemented Interfaces

GtkBin implements AtkImplementorIface.

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

GtkBin

typedef struct _GtkBin GtkBin;

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

GtkWidget *child;the child widget.


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
