Re: NSView drawing in tool

If I log into the machine with ssh or start the tool via cron as root
then I get (as expected)

xhost +
xhost:  unable to open display ""

This sort of backend would be very nice to have for the problem
described in earlier mails of this thread. I must admit that I need gui
for the first time in a tool. But for mapservers and the like that's
what is needed. It were really neat if GNUstep would support that. I
unfortunately don't have the expertise to write such a backend. :-(
Moreover this new backend should live well together with the normal art
backend on the same machine. When a user logs in on the console (or any
of the Thin Clients connected to the machine) and starts an app he
should get art backend, but when a tool is started within a ssh session
or by cron (with gui linked in) this tool should make use of the other
backend. This sounds more like additions of the kind

        if self is a tool than do that
        otherwise connect to back (art) and do something else

to gui than another backend to me!?
