GtkFileFilternew

Creates a new GtkFileFilter with no rules added to it.

Such a filter doesn’t accept any files, so is not particularly useful until you add rules with gtk_file_filter_add_mime_type(), gtk_file_filter_add_pattern(), gtk_file_filter_add_suffix() or gtk_file_filter_add_pixbuf_formats().

To create a filter that accepts any file, use:

GtkFileFilter *filter = gtk_file_filter_new ();
gtk_file_filter_add_pattern (filter, "*");
