That would do it. I think after that you would be set.

Kenneth,
we use the protocolbean in our
screenscraper.
So it is sort of headless it is working. We do trap the paint requests.
So it certainly should be possible.
Only adjustment that has to be made
is allowing the GUITerminal receive a protocol instead of creating one
itself.

Theoretically that should be possible. The reason I say theoretically
is that
the only thing the gui would do is attach listeners for the object
events
it
wants to see. So you should be able to send keys and as long as there
are no
listeners attached the events will not be sent.
After all the keys are sent and the screen you want is there you then
send
this
through to the GUITerminal which will obtain the information from the
object(s)
and then create the event consumers. Once the consumers are there
is when the
gui will start receiving the painting instructions.
Now I have not looked at those in a while but I am not sure why it
could
not be
done with what is there. Well I am saying what is there in CVS now
for
headless. Not sure how much code you used from the new headless code
or what
was changed but I can not see a problem with doing this at all.
Like I said it would kind of be what is being done with the Web5250
stuff.
If there is a problem with doing it this way I would not think it would
be to
much of a problem to change it to work that way.
Damn the flow in my head says it works this way but without an acutal
test....

Kenneth
