The gtk.HSeparator widget is a horizontal separator, used to group the widgets within a window. It displays a horizontal line with a shadow to make it appear sunken into the interface.
> The gtk.HSeparator widget is not used as a separator within menus. > To create a separator in a menu create an empty gtk.SeparatorMenuItem > widget using Separator.menuItemNew and add it to the menu with > Menu.shellAppend.
