Hello,
From the mail archives in March 2010, I see that simpletreemodel was throwing an \
error on exit. Phil responded saying that things were being destroyed in the wrong \
order on exit & that there would be a fix put into that night's snapshot. I don't \
believe the change ever made it into the source tree, as it still exhibits this \
behavior.
How can this example be fixed? I'm seeing the same error in my code (which is \
based largely off simpletreemodel) & would like to know what's wrong.

It's another example of things being destroyed in the wrong order when an
application terminates.
I've changed things (in tonight's snapshot) so that all top level widgets
are explicitly destroyed before the QApplication instance.

Thanks,
