-- * Detail
--
-- | 'FileChooserWidget' is a widget suitable for selecting files. It is the
-- main building block of a 'FileChooserDialog'. Most applications will only
-- need to use the latter; you can use 'FileChooserWidget' as part of a larger
-- window if you have special needs.
--
-- Note that 'FileChooserWidget' does not have any methods of its own.
-- Instead, you should use the functions that work on a 'FileChooser'.
