 * @Short_description: File chooser widget that can be embedded in other widgets
 * @Title: GtkFileChooserWidget
 * @See_also: #GtkFileChooser, #GtkFileChooserDialog
 *
 * #GtkFileChooserWidget is a widget suitable for selecting files.
 * It is the main building block of a #GtkFileChooserDialog.  Most
 * applications will only need to use the latter; you can use
 * #GtkFileChooserWidget as part of a larger window if you have
 * special needs.
 *
 * Note that #GtkFileChooserWidget does not have any methods of its
 * own.  Instead, you should use the functions that work on a
 * #GtkFileChooser.
