#include <gtk/gtk.h> struct GtkBin; GtkWidget* gtk_bin_get_child (GtkBin *bin); |
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.
