However MEDM is based on MOTIF and X11, systems/libraries that are getting into age. In reading this thread, I began to wonder what place Qt has in relation to X11. I've heard of Qt for many years but know little about it. After a little research, my impression that Qt always runs on top of a windowing system. As far as I can tell,
the only currently widely accepted and used cross-platform windowing system is the X Window System. And X11 is the latest and long-time incarnation of the X Window System-- they're really synonyms.
The widget toolkit that generally comes with X11 is Xt (in fact Qt's name is modeled after Xt). Motif and Xaw use Xt. Xt, GTK+, and Qt all use Xlib, the X11 library (Qt can use other window systems).
So I believe that Anton's statement above would more precise with "Motif and Xt".
Having used Motif and Xt many years ago, I can see why other widget toolkits could be more attractive-- of late, I've primarily used Tk, Java Swing, EDD, and EDM.
