Hi.
Maybe you can give some help here.
I'm starting to work with objects. And already have a problem. and I don't
where is my mistake.
This is a simple program where I do a matrix with a circle on the centre.
And I want to view it as an object using IDLgrImage, so I build the
hierarchy for that and the widgets needed. The event is only for managing
the resize of the window.
Here is the problem: If I run it in Unix with IDLde opened everything is
okay. It is okay also if I try to run on VM in windows. But if I try to run
it on Unix with VM is gives me an error:
% Restored file: IDLVMMAIN.
% X windows protocol error: BadMatch (invalid parameter attributes).
Xlib: sequence lost (0x10221 > 0x22e) in reply type 0x13!
Someone has the idea of what's wrong? It is something specifically for VM on
Unix? How can I fix it?
The complete code of the program I'm trying to run is on the end.
Cheers,
Nuno.

At just beginning I was hoping some advantages on programming with objects
graphics. Besides, volume visualization, interesting but not that much to
me, I like the fact that I could get any magnification by attributing a
matrix to IDLgrImage It is only necessary to resize the window and not the
matrix, as it is in direct graphics and only magnifies by natural numbers
(1,2,3, ..)
Cheers,
Nuno.
P.S. I suppose that Lockheed Martin doesn't like Ralph Nader. :)
I was curious and I looked for the Lockheed site. There's a picture of
hearth, a target city and inbound missile. selling NMD on the main page. And
of course, the stock price is also on the main page.

The balance, unless you are doing something that really does need
to be done in 3D space, has *never* been any good. At least if you
count the amount of effort it takes to write object graphics programs.
That's why the innovations in IDL 6.0 make about as much sense
to me as putting a permanent manned space station on the moon.
Who, exactly, needs it!?
Cheers,
David
P.S. If I really thought there was a chance in hell that
we would be going back to the moon in 10 years, I would
sure be buying Lockheed stock today. I wonder how much
they are contributing to Mr. Bush's re-election campaign. :-)

I suppose that for using 'idlde -vm=file' you need the full installation but
you don't need the license. But it's not the solution, I agree, but would
RSI do something about it?
All my work now has been in direct graphics, I was only trying to work with
object graphics looking for advantages but, at this time the balance isn't
very good.

Nuno,
You could write to RSI. The things I posted to c.l.idl-pvwave were
from RSI. Their support staff emailed me that info, so I posted it to
the list for others to see. I am not currently trying to work in the
VM with object graphics, and I have not tried most the solutions they
proposed.
To my mind, the usefulness of the VM is that it enables someone to
view and use my IDL procedure even if he does not have a license for
IDL. To use idlde, one needs a license, so
idlde -vm='file.sav'
is not really a solution to the VM problem on unix platforms, in my
opinion.
Remember, though: direct graphics work fine in the virtual machine.

Thanks. I saw your post and already tried that trick you suggest. Indeed it
works calling idlde -vm=file instead of idl -vm=file
Initially I didn't try that solution because you say in there that it worked
only once.
I don't if you can say one more thing or if you suggest me to also write to
RSI. It is supposed RSI to fix the problem and get a solution for those who
have IDL 6.0 or we are talking of fixing it to version 7.0?
Thanks again,
Nuno.

Nuno, the RSI have not fixed this problem yet. If you look at the postings
from Dec. 18 and 25 you will see that they have a few tricks to get object
graphics to work in the virtual machine, but nothing robust.
