+ * SECTION: gimpfileentry
+ * @title: GimpFileEntry
+ * @short_description: Widget for entering a filename.
+ * @see_also: #GimpPathEditor
+ *
+ * This widget is used to enter filenames or directories.
+ *
+ * There is a #GtkEntry for entering the filename manually and a "..."
+ * button which will pop up a #GtkFileChooserDialog.
+ *
+ * You can restrict the #GimpFileEntry to directories. In this
+ * case the filename listbox of the #GtkFileChooser dialog will be
+ * set to directory mode.
+ *
+ * If you specify @check_valid as #TRUE in gimp_file_entry_new() the
+ * entered filename will be checked for validity and a pixmap will be
+ * shown which indicates if the file exists or not.
+ *
+ * Whenever the user changes the filename, the "filename_changed"
+ * signal will be emitted.
