/**
 * SECTION:gtkfontsel
 * @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.
