filenameSpecifies a potential filename.
Description
Filename evaluation is handled in an operating system-dependent fashion by a file predicate procedure of type XtFilePredicate. An XtFilePredicate is registered in calls to XtFindFile or XtResolvePathname. This procedure will be called with a string that is potentially a filename. The procedure returns True if this string specifies a file that is appropriate for the intended use; otherwise, the procedure returns False.
