Staffan,
I don't thing there is any "preferred" one. A third approach would be to
the use the propSheet attribute to communicate through the owner dialog.
It seems to me that a "progress" dialog is something that just begs to be
reusable. So, I would probably not use the querySiblings method. As you
design the page that has the progress bars, you could think about which
methods of that dialog could be generically used in a progress dialog.
Then extract those methods into a mixin class that could be inherited to
produce a progress dialog useful in any situation.
