I used what was probably a different version than you did (SunAda 1.0,
Motif 1.1.2), and would not reccomend the product.  It had several
bugs that took us days to program circles around.  For example:

Xm.ListGetSelectedItems did not work.
Xt.AppAddWorkProc did not work.
etc.

One of the major gripes I have was stylistic rather than functional.
AXI uses a different data type for the indices of the resource array
and the number of resources passed to Xt.SetArg.  In C you do:

n=0;
XtSetArg(Resources(n), XmNfoo, BAR); n++;
XtSetArg(Resources(n), XmNbaro, FOO); n++;
...
XtSetValues(myWidget, Resources, n);

But AXI used Cardinal for the indices to Resources, and some other
type of (incompatible) type for the count parameter to XtSetValues, et
al.


I haven't tried either a new version of AXI's bindings, or the SERC
bindings (available from ICS), but I would certainly look around a bit
before deciding on bindings for my next project.
