public void add_custom (FileFilterFlags needed, owned FileFilterFunc func)
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.
