Problem solved. use 'command = Calc' to call my Calc function but ignore
the argument passed to it. Create a list with the following elements -
a.get(), b.get() and c.get(). Every time a scale slider is moved, Calc
will retrieve the current scale values and I can do with them whatever I
want...

It should work if you w
Some time ago I wrote a little program in Tcl/Tk that took the values
from 3 sliders and performed a calculation using these values. The
