Hello

###

% wm geometry . 400x400
% . configure -background yellow

% pack [frame .f1 -container 1] -fill both -expand yes
% toplevel .top1 -use [winfo id .f1] -background red
% bind .top1 <Destroy> "puts {DESTROY .top1}"

% pack [frame .top1.f2 -container 1] -fill both -expand yes

% toplevel .top2 -use [winfo id .top1.f2] -background green
% bind .top2 <Destroy> "puts {DESTROY .top2}"

% destroy .top2

## if I destroy .top2 then the output is:
% DESTROY .top2
% DESTROY .top1

Why, I only destroy .top2 I think I only should get:
% DESTROY .top2

## If I run:
% winfo exist .top1
## I get:
% 1

##

It this a normal behavior?

Regards

Manfred

Make both bindings use %W to see which widget exactly gets the event:

bind .top1 <Destroy> "puts {DESTROY top1/%W}"
bind .top2 <Destroy> "puts {DESTROY top2/%W}"

=>
destroy .top2
DESTROY top2/.top2
DESTROY top1/.top1.f2

So, destroying .top2 alse destroys .top1.f2, but not .top1.
I have not checked the details of -container and -use, so I can't
comment on whether that is to be expected...

Thank's

I know that .top1 isn't destroyed, "Puts {DESTROY .top1}" is only for
testing.
It looks like .top1 was destroyed, but it wasn't, but the event was
triggerd.

Now I use
wm protocol .top1 WM_DELETE_WINDOW "puts {DESTROY .top1}"
wm protocol .top1 WM_DELETE_WINDOW "puts {DESTROY .top2}"

This work for me like expected.

regards

Manfred
