Question

When I execute the following code

#!/bin/sh
# \
exec wish "$0" ${1+"$@"}

set w .main
toplevel $w
wm title $w "FOO"

I got two windows instead one.
I tried to hide wish “.” window by :

wm state . withdrawn

but anyway when I close my toplevel window the main process still not finished.
My question is how to destroy wish window when I close toplevel window and completely finish the process?

Answer 1

If you only want 1 window, why not do your manipulations on the . window?

wm title . "FOO"

Then, when the user closes that window, your app will finish.
