You call a function by sup[plying the parens after its name.
So the function gets called here. The normal way to circumvent
that in Tkinter is to use a lambda expression to defer execution,
like so:
B4=Button(main, text='fill text', command=lambda wgt=ofield : genF(wgt))
B4.pack()
main.mainloop()
I'm not sure you need the second mainloop. I think the
root level mainloop will work for your window too.
