+/* Menus
+ *
+ * There are several widgets involved in displaying menus. The
+ * GtkMenuBar widget is a menu bar, which normally appears horizontally
+ * at the top of an application, but can also be layed out vertically.
+ * The GtkMenu widget is the actual menu that pops up. Both GtkMenuBar
+ * and GtkMenu are subclasses of GtkMenuShell; a GtkMenuShell contains
+ * menu items (GtkMenuItem). Each menu item contains text and/or images
+ * and can be selected by the user.
+ *
+ * There are several kinds of menu item, including plain GtkMenuItem,
+ * GtkCheckMenuItem which can be checked/unchecked, GtkRadioMenuItem
+ * which is a check menu item that's in a mutually exclusive group,
+ * GtkSeparatorMenuItem which is a separator bar, GtkTearoffMenuItem
+ * which allows a GtkMenu to be torn off, and GtkImageMenuItem which
+ * can place a GtkImage or other widget next to the menu text.
+ *
+ * A GtkMenuItem can have a submenu, which is simply a GtkMenu to pop
+ * up when the menu item is selected. Typically, all menu items in a menu bar
+ * have submenus.

-        Instead of calling gtk_drag_dest_set() and connecting to #GtkWidget signals, you create

-        The ::drag-motion signal has been renamed to #GtkDragSource::accept, and instead of
-        ::drag-data-received, you need to use async read methods on the #GdkDrop object, such
-        as gdk_drop_read_value_async() or gdk_drop_read_text_async().
