* 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:

* 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);
