module Graphics.UI.Gtk.Buttons.Button (
-- * Detail
--
-- | The 'Button' widget is generally used to attach a function to that is
-- called when the button is pressed. The various signals and how to use them
-- are outlined below.
--
-- The 'Button' widget can hold any valid child widget. That is it can hold
-- most any other standard 'Widget'. The most commonly used child is the
-- 'Label'.
