In general, if you want to do something non-portably in XVT, you should
be able to do most anything the underlying toolkit, window system, and
operating system allow. You make a good point however. In fact, I will
be presenting a talk at the upcoming XVT Conference this August which
will include the topic of "How to add an arbitrary motif widget to an
XVT window."  It is my belief that any widget should be accessible,
but the real question I need to explore is, just how hard will this
be.  Now I'm not sure how much this would go to satisfy your point, but
I do intend to answer the general question of creating a widget, putting
it in an XVT window, and handling its related callbacks. I won't know the
results for a while, since I wont be doing that work until next month.
