To whom this may concern,
Attatched is the source code, which
demonstrates a
problem I am having making a GUI for my python project work. Both
files need to be in the same folder.
My code writes to a text file 'table.txt', and 'table.txt' is displayed in
the GUI. The user can generate new data at the click of a button
which re-writes 'table.txt', but I can only add the new table to the GUI
window rather than 'update' the existing one.
Any assistance would be much appreciated,
Regards,
Christian Wood.

Question: How do I simply update a table from within TKinter?, this
current program just adds the new text box, so is there a way of removing
the old one first?, or do I have to try a completely different approach?
I am completely new to TKinter, and GUI programming, my background is just
solving numerical problems using Numeric and math and pylab.
