Adds rule to a filter that allows files based on a custom callback function. The bitfield Needed which is passed in provides information about what sorts of information that the filter function needs; this allows GTK+ to avoid retrieving expensive information when it isn't needed by the filter. Since: gtk+ 2.4 "needed": bitfield of flags indicating the information that the custom filter function needs. "func": callback function; if the function returns True, then the file will be displayed. "data": data to pass to Func "notify": function to call to free Data when it is no longer needed.
