The problem is rather that much of the interesting information about UNO objects is only available dynamically, at runtime. The static type information that is available is indeed often just only XInterface (or some other basic interface type) or ANY. So you generally face the same problems wrt code completion as you face with any of today's dynamic programming languages. UNO has the concepts to do better, but most parts of the API do not make use of them. -Stephan _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
