DropdownList のボタンが欲しい

DropdownList の右にある、下向き三角のボタンが欲しい。

オープンコントロールから探しました。

Code:

{def owner:StandardDropdownListUI = {StandardDropdownListUI}}
{def sdh:StandardDropdownHelper = {StandardDropdownHelper owner}}
{value sdh.dropdown-button-graphic}

見栄えだけなら↓

Code:

{CommandButton
            takes-focus? = false,
            show-focus? = false,
            active-traversal-container = null,
            control-appearance-changeable? = true,
            label =
                {TriangleControlPart.from-dimension
                    TriangleDirection.down,
                    5, 7, offset = 2
                },
            height = {add-stretch before? = true, after? = true},
            {on Action do
                {self.textfield.populate-from-strings
                    self.provider.list-item-string}
            }
        }

SkinnableDropdownListUIを使っているなら、以下の様に取れます。

{ui.get-tagged-content "drop-button"}
