-- * Detail
--
-- | 'ToolButton's are 'ToolItems' containing buttons.
--
-- Use 'toolButtonNew' to create a new 'ToolButton'. Use
-- 'toolButtonNewWithStock' to create a 'ToolButton' containing a stock item.
--
-- The label of a 'ToolButton' is determined by the properties
-- \"label_widget\", \"label\", and \"stock_id\". If \"label_widget\" is
-- not @Nothing@,
-- then that widget is used as the label. Otherwise, if \"label\" is
-- not @Nothing@,
-- that string is used as the label. Otherwise, if \"stock_id\" is not
-- @Nothing@, the label is
-- determined by the stock item. Otherwise, the button does not have a label.
--
-- The icon of a 'ToolButton' is determined by the properties
-- \"icon_widget\" and \"stock_id\". If \"icon_widget\" is not @Nothing@, then
-- that widget is used as the icon. Otherwise, if \"stock_id\" is not @Nothing@,
-- the icon is determined by the stock item. Otherwise, the button does not have
-- a label.
