Well, I ran into trouble at first too when trying to do this. In the
end I realized that deiconify(), tkraise() and focus() need to be
called once the Tk object's mainloop is already running. And that they
must be called from the same thread that the mainloop is running in,
so threads must be avoided.
This seems to do the trick:
top = Tk()
text = Text(top)
Of course, using 'after' like this is an ugly hack. If the call to
mainloop is delayed somehow, then the window will not be raised
(that's why I used a 50 millisecond delay). I played around with
cleaner possibilities but ran into some difficulties... It's too late
at night, I'll give it another look tomorrow.
