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.
