47  * @Short_description: A deprecated widget for a menu item with an icon
48  * @Title: GtkImageMenuItem
49  *
50  * A GtkImageMenuItem is a menu item which has an icon next to the text label.
51  *
52  * This is functionally equivalent to:
53  *
54  * |[<!-- language="C" -->
55  *   GtkWidget *box = gtk_box_new (GTK_ORIENTATION_HORIZONTAL, 6);
56  *   GtkWidget *icon = gtk_image_new_from_icon_name ("folder-music-symbolic", GTK_ICON_SIZE_MENU);
57  *   GtkWidget *label = gtk_label_new ("Music");
58  *   GtkWidget *menu_item = gtk_menu_item_new ();
59  *
60  *   gtk_container_add (GTK_CONTAINER (box), icon);
61  *   gtk_container_add (GTK_CONTAINER (box), label);
62  *
63  *   gtk_container_add (GTK_CONTAINER (menu_item), box);
64  *
65  *   gtk_widget_show_all (menu_item);
66  * ]|
67  *
68  * Note that the user may disable display of menu icons using
69  * the #GtkSettings:gtk-menu-images setting, so make sure to still
70  * fill in the text label. If you want to ensure that your menu items
71  * show an icon you are strongly encouraged to use a #GtkMenuItem
72  * with a #GtkImage instead.
73  *
74  * #GtkImageMenuItem has been deprecated since GTK+ 3.10. If you want to
75  * display an icon in a menu item, you should use #GtkMenuItem and pack a
76  * #GtkBox with a #GtkImage and a #GtkLabel instead. You should also consider
77  * using #GtkBuilder and the XML #GMenu description for creating menus, by
78  * following the [GMenu guide][https://developer.gnome.org/GMenu/]. You should
79  * consider using icons in menu items only sparingly, and for "objects" (or
80  * "nouns") elements only, like bookmarks, files, and links; "actions" (or
81  * "verbs") should not have icons.
82  *
83  * Furthermore, if you would like to display keyboard accelerator, you must
84  * pack the accel label into the box using gtk_box_pack_end() and align the
85  * label, otherwise the accelerator will not display correctly. The following
86  * code snippet adds a keyboard accelerator to the menu item, with a key
87  * binding of Ctrl+M:
88  *
89  * |[<!-- language="C" -->
90  *   GtkWidget *box = gtk_box_new (GTK_ORIENTATION_HORIZONTAL, 6);
91  *   GtkWidget *icon = gtk_image_new_from_icon_name ("folder-music-symbolic", GTK_ICON_SIZE_MENU);
92  *   GtkWidget *label = gtk_accel_label_new ("Music");
93  *   GtkWidget *menu_item = gtk_menu_item_new ();
94  *   GtkAccelGroup *accel_group = gtk_accel_group_new ();
95  *
96  *   gtk_container_add (GTK_CONTAINER (box), icon);
97  *
98  *   gtk_label_set_use_underline (GTK_LABEL (label), TRUE);
99  *   gtk_label_set_xalign (GTK_LABEL (label), 0.0);
100  *
101  *   gtk_widget_add_accelerator (menu_item, "activate", accel_group,
102  *                               GDK_KEY_m, GDK_CONTROL_MASK, GTK_ACCEL_VISIBLE);
103  *   gtk_accel_label_set_accel_widget (GTK_ACCEL_LABEL (label), menu_item);
104  *
105  *   gtk_box_pack_end (GTK_BOX (box), label, TRUE, TRUE, 0);
106  *
107  *   gtk_container_add (GTK_CONTAINER (menu_item), box);
108  *
109  *   gtk_widget_show_all (menu_item);
