/**
 * SECTION:gtkimagemenuitem
 * @Short_description: A deprecated widget for a menu item with an icon
 * @Title: GtkImageMenuItem
 *
 * A GtkImageMenuItem is a menu item which has an icon next to the text label.
 *
 * This is functionally equivalent to:
 *
 * |[<!-- language="C" -->
 *   GtkWidget *box = gtk_box_new (GTK_ORIENTATION_HORIZONTAL, 6);
 *   GtkWidget *icon = gtk_image_new_from_icon_name ("folder-music-symbolic", GTK_ICON_SIZE_MENU);
 *   GtkWidget *label = gtk_label_new ("Music");
 *   GtkWidget *menu_item = gtk_menu_item_new ();
 *
 *   gtk_container_add (GTK_CONTAINER (box), icon);
 *   gtk_container_add (GTK_CONTAINER (box), label);
 *
 *   gtk_container_add (GTK_CONTAINER (menu_item), box);
 *
 *   gtk_widget_show_all (menu_item);
 * ]|
 *
 * Note that the user may disable display of menu icons using
 * the #GtkSettings:gtk-menu-images setting, so make sure to still
 * fill in the text label. If you want to ensure that your menu items
 * show an icon you are strongly encouraged to use a #GtkMenuItem
 * with a #GtkImage instead.
 *
 * #GtkImageMenuItem has been deprecated since GTK+ 3.10. If you want to
 * display an icon in a menu item, you should use #GtkMenuItem and pack a
 * #GtkBox with a #GtkImage and a #GtkLabel instead. You should also consider
 * using #GtkBuilder and the XML #GMenu description for creating menus, by
 * following the [GMenu guide][https://developer.gnome.org/GMenu/]. You should
 * consider using icons in menu items only sparingly, and for "objects" (or
 * "nouns") elements only, like bookmarks, files, and links; "actions" (or
 * "verbs") should not have icons.
 *
 * Furthermore, if you would like to display keyboard accelerator, you must
 * pack the accel label into the box using gtk_box_pack_end() and align the
 * label, otherwise the accelerator will not display correctly. The following
 * code snippet adds a keyboard accelerator to the menu item, with a key
 * binding of Ctrl+M:
 *
 * |[<!-- language="C" -->
 *   GtkWidget *box = gtk_box_new (GTK_ORIENTATION_HORIZONTAL, 6);
 *   GtkWidget *icon = gtk_image_new_from_icon_name ("folder-music-symbolic", GTK_ICON_SIZE_MENU);
 *   GtkWidget *label = gtk_accel_label_new ("Music");
 *   GtkWidget *menu_item = gtk_menu_item_new ();
 *   GtkAccelGroup *accel_group = gtk_accel_group_new ();
 *
 *   gtk_container_add (GTK_CONTAINER (box), icon);
 *
 *   gtk_label_set_use_underline (GTK_LABEL (label), TRUE);
 *   gtk_label_set_xalign (GTK_LABEL (label), 0.0);
 *
 *   gtk_widget_add_accelerator (menu_item, "activate", accel_group,
 *                               GDK_KEY_m, GDK_CONTROL_MASK, GTK_ACCEL_VISIBLE);
 *   gtk_accel_label_set_accel_widget (GTK_ACCEL_LABEL (label), menu_item);
 *
 *   gtk_box_pack_end (GTK_BOX (box), label, TRUE, TRUE, 0);
 *
 *   gtk_container_add (GTK_CONTAINER (menu_item), box);
 *
 *   gtk_widget_show_all (menu_item);
 * ]|
