GtkBin

GtkBin — A container with just one child

Synopsis


#include <gtk/gtk.h>


                    GtkBin;
GtkWidget*          gtk_bin_get_child                   (GtkBin *bin);

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 {
  GtkContainer container;

  GtkWidget *child;
} GtkBin;

The GtkBin 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
