Thank you very much.I had actually misinterpreted the "textvariable" property for some kind of "storage for each Button". I am actually developing an app where multiple buttons have a single event handler.So i thought the "textvariable" property might be used to store some info about each of the Button so that the handler can differentiate between the callers by examining the property.Now i achieved similar functionality with callbacks because button command handlers dont receive any additional arguments.
