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.
Wim.

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....
Regards
Kenneth
