Ah, yes. I remember this now, Stein Vidar. Good ideas. But
I see it involves objects (as it almost has to). I fooled
around with a color "lurker" object some time ago. It would
lurk in the background paying attention to when color tables
were loaded and if a window it was "managing" was open it
would redisplay the graphics command in that window by
calling the Draw method of a graphics object.

I recall it working great (I accidentally deleted the
code in a disk cleaning frenzy) with the graphics objects
I was working with at the time (plot and contour objects
that used direct graphics calls). But I remember thinking
that it wouldn't be too hard to write an XWindow-like
object wrapper around *any* graphics command, so that
windows could be automatically updated.

I recall that I needed (or *thought* I needed a singleton
object). I've just re-read JD's thoughts on that and have
some ideas on how it could be implemented to serve this
need.

But...it will have to wait. My mother arrives for a visit
tomorrow and if she sees my house in this state it will
go badly for me. :-(

Cheers,

David
