QUESTION : Do you think that it would be more clear if the above functions and procedures regarding a query-widget would be named in a similar manner as binded variable controls ? That mean, mfqry:open and mfqry:updatecontrols instead of .mf.qry:open and .mf.qry:updatecontrols -?

+?

The only advantage of .mf.qry:open is that is much closer to the Tk method of referring objects within a window and it may give to the programmer the feeling that he is using a object-oriented widget. Since I cannot use further for naming binded variables a similar manner (.mf.qry.salary) -it might be possible to abandon that naming convention .
