A filter for selecting a file subset. 
A Gtk::FileFilter can be used to restrict the files being shown in a Gtk::FileChooser. Files can be filtered based on their name (with add_pattern()), on their mime type (with add_mime_type()), or by a custom filter function (with add_custom()).
Filtering by mime types handles aliasing and subclassing of mime types; e.g. a filter for text/plain also matches a file with mime type application/rtf, since application/rtf is a subclass of text/plain. Note that Gtk::FileFilter allows wildcards for the subtype of a mime type, so you can e.g. filter for image/*.
Normally, filters are used by adding them to a Gtk::FileChooser. See Gtk::FileChooser::add_filter(). But it is also possible to manually use a filter on a file with filter().
