GtkFileSelection::complete
void complete(string pattern);
complete() will try
to match the pattern given by the programmer to a valid file name
in the current directory, or to a valid directory name on the
current drive. This is useful when, for example, wishing to
hard-code a search for a specific extension into an application.
Where a full match is made, the matched file name will appear in
both the file list and the text entry field of the file selection
dialog. If only partial matches can be found, the file list will
contain the resulting file names and the text entry field will
contain the closest matched string (not the full file name).
Note that only a single wildcard field is effective here.
$fs->complete("*.php");
