/* Menus
*
- * GTK+ includes a number of widgets for menus of actions.
- * GtkMenu is a drop-down menu, GtkMenuBar a horizontal menu bar.
- * Each of these widgets can hold various types of menuitem.
- * As well as the base type, GtkMenuItem, there are GtkCheckMenuItem,
- * GtkRadioMenuItem and GtkTearoffMenuItem.
+ * 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.
+ *
+ * GtkUIManager provides a higher-level interface for creating menu bars
+ * and menus; while you can construct menus manually, most people don't
+ * do that. There's a separate demo for GtkUIManager.
