FileFilter.this

Creates a new gtk.file_filter.FileFilter 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.FileFilter.addMimeType, gtk.file_filter.FileFilter.addPattern, gtk.file_filter.FileFilter.addSuffix or gtk.file_filter.FileFilter.addPixbufFormats.

To create a filter that accepts any file, use:

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