Allan -
I thought you might be interested in my POS_WIDGET.PRO routine that
lets you position a widget in various ways, most in relation to
a parent widget. It will at least give you an idea of how to use
screen and widget geometry to position things.
You can use this routine to position widgets before or after they
have been realized.
You can download this at:
ftp://bial8.ucsd.edu/pub/software/idl/share/idl_share.tar.gz
There is a file POS_WIDGET.DOC documentation file.

I certainly wouldn't give up on this until after I had tested
it a little. :-)

In general I concur. Unfortunately this really throws a wrench into a
project I have been working on (and off) for the couple of months. I have
been writing a IDL "Foundations" Class library, similar in functionality to
MFC on windows. While creating a collapsible list box container class, I
came upon the need to move base widgets after they are realized. Bad news
for me.
Thanks anyhoo,
Allan

Sure. If I have a customer that is slow to pay his bill,
I like to write a little timer event that at random times
will move the application to some other location on the
display. Drives 'em crazy. They pay up quickly. :-)

IDL has gotten much better at this than it used to be.
I find that these "dangerous" things are almost always
carried out successfully these days. I even wrote a droplist
widget this week that can destroy itself and come back to life
in a new incarnation. Still, you can't *always* move things
on *all* window managers.
The bottom line is to not get too hung up on where things
are positioned. Users wielding mice often have ideas of
their own that don't always correspond to your completely
understandable aesthetic sense.
Happy Holidays!
