/**
* SECTION:gtkfontchooser
- * @Short_description: A widget for selecting fonts
+ * @Short_description: Interface implemented by widgets displaying fonts
* @Title: GtkFontChooser
- * @See_also: #GtkFontChooserDialog
- *
- * The #GtkFontChooser widget lists the available fonts, styles and sizes,
- * allowing the user to select a font.
- * It is used in the #GtkFontChooserDialog widget to provide a dialog box for
- * selecting fonts.
+ * @See_also: #GtkFontChooserDialog, #GtkFontChooserWidget, #GtkFontButton
*
- * To set the font which is initially selected, use
- * gtk_font_chooser_set_font_name().
- *
- * To get the selected font use gtk_font_chooser_get_font_name().
- *
- * To change the text which is shown in the preview area, use
- * gtk_font_chooser_set_preview_text().
+ * #GtkFontChooser is an interface that can be implemented by widgets
+ * displaying the list of fonts. In GTK+, the main objects
+ * that implement this interface are #GtkFontChooserWidget,
+ * #GtkFontChooserDialog and #GtkFontButton.
*
* Since: 3.2
