Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I am learning Tk. I want that the text widget displays the vertical scrollbar only if this is needed, otherwise it should hide. This is normal practice today. In the Widget POD I could not find any reference to this feature, so I guess it does not exist. Has anybody been able to achieve this? On the Internet I only found a Python code, but I do not speak Python. Any suggestion?
