> Basically, what we want to do is ...

I have been prototyping software for the new control center being
designed for NASA-Marshall. It will of course have similar,
real-time X display requirements.

We are building a display contruction and operation prototype which
lets the user build/operate a display consisting of plots, virtual
instruments, digital text, graphics, and other objects. The primary
thing you would probably be interested in is the widgets we are using.
At this time, we are using the DynaGraphX data widgets, which are
basically the DataViews graphic objects with an Xt interface. I sel-
ected DynaGraphX because it has a wide range of widgets and IHMO,
is well suited to real-time. It also supports the features you
described. I also considered and may use in the future, widgets from:

     XRT/Graph   (KL Group) - nice appearance and lots of flex.
     Xtra        (GSS)      - ditto
     INT widgets (INT)      - nice widgets initially for oil apps.

A good source of info on widgets is the Integrated Computing
Solutions (ICS) widget databook. It is a listing of COTS and free
widgets from which you can pick and choose. There is also a Free
Widget Foundation (FWF) from which you can obtain various free
widgets. The ICS databook references some of the FWF widgets. I
have not checked up on the FWF in a while and it may offer many
more widgets.

We also developed a custom widget which supports all the digital
text, static graphic, and dynamic graphic display. All the code
I have described is owned by NASA, so you can get ahold of it if
you really want to.

> Right now we're using X11R4/5 ...

I use R5 and Motif (and obviously Xt) with no problems.
