(ot) tcl/tk programming problem

[almquist paul <almquist cvtc-cis chippewa tec wi us>]

Hi all--

1) Can anyone recommend a tcl/tk programming list?  I have not run
        across any yet.  That would be a better place for my question
        but since I have your attention, here it is:

2) I have 3 different applications I would like to write in tcl/tk and
        all require an array of buttons in the user interface.  Rather
        than writing a separate procedure to be called by each button
        command I would like to have just one procedure.  In that
        procedure it would perform the required action based on the
        button that was clicked by the user.  Basically the same processing
        for all buttons, just different data to be used.

        Herein lies the problem:
        I have yet to find out where the event information is stored
        to know what button was clicked.  None of the books and other
        documentation I have has given up that secret.

        Where is this golden information stored?  Or is it even stored
        somewhere?   Or is there a better way to do this?

        Of course I am doing this on RHL 6.2 with tcl/tk 8.0.5.

Thanks for helping,
paul
