gtk:file-filter-new ()

The new gtk:file-filter object.

Creates a new file filter with no rules added to it. Such a file filter does not accept any files, so is not particularly useful until you add rules with the gtk:file-filter-add-mime-type, the gtk:file-filter-add-pattern, or gtk:file-filter-add-pixbuf-formats functions. To create a file filter that accepts any file, use:

(let ((filter (gtk:file-filter-new)))
  (gtk:file-filter-add-pattern filter "*")
  ... )
