That's right. A base widget without COLUMN or ROW set is
a bulletin board base widget. It's children are stacked
on top of one another.

I'm not sure that is any more general than this. You
can put any two draw widgets in any bulletin board
base. You could even write your own compound widget
that did this, if you wanted to. I guess *that* would
be pretty general. :-)

No, I leave this up to Pavel. :-)

My Gosh! I think !Window is a throw-back all the way
to IDL 1.0. That was a LONG time ago! But you are right,
it does seem to work. One of those things they kept meaning
to throw out, I guess.
