- * @Short_description: Deprecated widget for selecting fonts
- * @Title: GtkFontSelection
- * @See_also: #GtkFontSelectionDialog, #GtkFontChooser
- *
- * The #GtkFontSelection widget lists the available fonts, styles and sizes,
- * allowing the user to select a font.
- * It is used in the #GtkFontSelectionDialog widget to provide a dialog box for
- * selecting fonts.
- *
- * To set the font which is initially selected, use
- * gtk_font_selection_set_font_name().
- *
- * To get the selected font use gtk_font_selection_get_font_name().
- *
- * To change the text which is shown in the preview area, use
- * gtk_font_selection_set_preview_text().
- *
- * In GTK+ 3.2, #GtkFontSelection has been deprecated in favor of
- * #GtkFontChooser.
