Hi Vikas,

Please find as an example the attached macro number.C. I have created it as simple as possible. It contains one number entry and one frame where the value of this number entry is displayed when it is changed. For input you can use the keyboard and hit Return key in the end or the number entry buttons. I have no idea how do you read your data, what format it has, etc. so this part of the code is up of your needs.

The example is based on the signals/slots communication mechanizm. Please read the corresponding chapter in the ROOT User's Guide at: ftp://root.cern.ch/root/doc/chapter24.pdf (page 346). See also the examples at: http://root.cern.ch/root/HowtoSignalSlot.html

Cheers, Ilka
