    <summary>A text entry field with a dropdown list</summary>
    <remarks>
      <para>
        The <see cref="T:Gtk.Combo" /> widget consists of a single-line text entry field and a
        drop-down list. The drop-down list is displayed when the user clicks
        on a small arrow button to the right of the entry field.
      </para>
      <para>
        The drop-down list is a <see cref="T:Glib.List" /> widget and can be accessed using the
        list member of the <see cref="T:Gtk.Combo" />. List elements can contain arbitrary
        widgets, but if an element is not a plain label, then you must use
        the <see cref="M:Glib.List.SetItemString()" /> function. This sets the string which
        will be placed in the text entry field when the item is selected.
      </para>
      <para>
        By default, the user can step through the items in the list using the
        arrow (cursor) keys, though this behaviour can be turned off with
        <see cref="P:Gtk.Combo.UseArrows" /> = <see langword="false" />.
