+ * @See_also: #GtkFontChooser, #GtkDialog
+ *
+ * The #GtkFontChooserDialog widget is a dialog box for selecting a font.
+ *
+ * To set the font which is initially selected, use
+ * gtk_font_chooser_dialog_set_font_name().
+ *
+ * To get the selected font use gtk_font_chooser_dialog_get_font_name().
+ *
+ * To change the text which is shown in the preview area, use
+ * gtk_font_chooser_dialog_set_preview_text().
+ *
+ * <refsect2 id="GtkFontChooserDialog-BUILDER-UI">
+ * <title>GtkFontChooserDialog as GtkBuildable</title>
+ * The GtkFontChooserDialog implementation of the GtkBuildable interface
+ * exposes the embedded #GtkFontChooser as internal child with the
+ * name "font_chooser". It also exposes the buttons with the names
+ * "select_button" and "cancel_button.
