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
calculation was of course automatically repeated each time a slider was
moved.
It is proving most difficult in Python. How do I pass the .get() values
to my

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...
