+ * SECTION:gtkmenu
+ * @Short_description: A menu widget
+ * @Title: GtkMenu
+ *
+ * A #GtkMenu is a #GtkMenuShell that implements a drop down menu
+ * consisting of a list of #GtkMenuItem objects which can be navigated
+ * and activated by the user to perform application functions.
+ *
+ * A #GtkMenu is most commonly dropped down by activating a
+ * #GtkMenuItem in a #GtkMenuBar or popped up by activating a
+ * #GtkMenuItem in another #GtkMenu.
+ *
+ * A #GtkMenu can also be popped up by activating a #GtkOptionMenu.
+ * Other composite widgets such as the #GtkNotebook can pop up a
+ * #GtkMenu as well.
+ *
+ * Applications can display a #GtkMenu as a popup menu by calling the 
+ * gtk_menu_popup() function.  The example below shows how an application
+ * can pop up a menu when the 3rd mouse button is pressed.  
+ *
+ * <example>
+ * <title>Connecting the popup signal handler.</title>
+ * <programlisting>
+ *   /<!---->* connect our handler which will popup the menu *<!---->/
+ *   g_signal_connect_swapped (window, "button_press_event",
+ *	G_CALLBACK (my_popup_handler), menu);
+ * </programlisting>
+ * </example>
+ *
+ * <example>
+ * <title>Signal handler which displays a popup menu.</title>
+ * <programlisting>
+ * static gint
+ * my_popup_handler (GtkWidget *widget, GdkEvent *event)
+ * {
+ *   GtkMenu *menu;
+ *   GdkEventButton *event_button;
+ *
+ *   g_return_val_if_fail (widget != NULL, FALSE);
+ *   g_return_val_if_fail (GTK_IS_MENU (widget), FALSE);
+ *   g_return_val_if_fail (event != NULL, FALSE);
+ *
+ *   /<!---->* The "widget" is the menu that was supplied when 
+ *    * g_signal_connect_swapped() was called.
+ *    *<!---->/
+ *   menu = GTK_MENU (widget);
+ *
+ *   if (event->type == GDK_BUTTON_PRESS)
+ *     {
+ *       event_button = (GdkEventButton *) event;
+ *       if (event_button->button == 3)
+ *         {
+ *           gtk_menu_popup (menu, NULL, NULL, NULL, NULL, 
+ *                           event_button->button, event_button->time);
+ *           return TRUE;
+ *         }
+ *     }
+ * 
+ *   return FALSE;
+ * }
