module Graphics.UI.Gtk.Selectors.FontSelection (
-- * Detail
--
-- | The 'FontSelection' widget lists the available fonts, styles and sizes,
-- allowing the user to select a font. It is used in the 'FontSelectionDialog'
-- widget to provide a dialog box for selecting fonts.
--
-- To set the font which is initially selected, use
-- 'fontSelectionSetFontName'.
--
-- To get the selected font use 'fontSelectionGetFontName'.
--
-- To change the text which is shown in the preview area, use
-- 'fontSelectionSetPreviewText'.
