Humm. Well, I guess I knew that. But I still prefer the
old tried and true way of a CLEANUP routine. :-)

Cheers,

Oh, it can't possibly be that easy, can it? :-(

Cheers,

P.S. Let's just say the afternoon session may be a bit
longer than I originally intended as I cover this new
material.

Set the /TLB_KILL_REQUEST_EVENTS to WIDGET_BASE and define an event
handler.

Good luck,

I'm guessing you want to do this because your "cleanup"
code is in your EXIT button event handler. This is the
wrong place to put it. Rather, your "cleanup" code should
be in a CLEANUP (if you assign it to the TLB with XMANAGER)
or KILL_NOTIFY (if to assing it with the KILL_NOTIFY keywword)
callback procedure that is called when the widget associated
with the callback is killed.

Cheers,

David

Of course you are right; I actually refered to the case where you want
to inhibit the window being closed (e.g., if you want to have the
closing confirmed), but forgot to mention that explicitly ...
