module Graphics.UI.Gtk.Selectors.FileChooserButton (
-- * Detail
--
-- | The 'FileChooserButton' is a widget that lets the user select a file. It
-- implements the 'FileChooser' interface. Visually, it is a file name with a
-- button to bring up a 'FileChooserDialog'. The user can then use that dialog
-- to change the file associated with that button. This widget does not support
-- setting the \"select-multiple\" property to @True@.
--
-- The 'FileChooserButton' supports the 'FileChooserAction's
-- 'FileChooserActionOpen' and 'FileChooserActionSelectFolder'.
