[ltk-user] Does LTK supports Cells or something similar?

Hi My first question: Is there a way to search in all the archives of LTK mailing list? If yes, how one does do that? My second question LTK-related: Does LTK support Cells, or similar kind of auto-update mechanism? What i practically want to do is to have a global variable, whose change triggers the update of various widgets. Thank you Matus
