Wow, somebody who actually claims to prefer Motif to Tk... I guess
if you read netnews long enough you'll see everything at least once.
If you have ever tried to program in Motif and figure out the bizarre
Xt "object system" you wouldn't be so emphatic about this. It would
be nice if Tk had a well-defined C or C++ API, but even without it
the toolkit itself is faster, better-written, and cleaner by far than
Motif. The three best reasons to use Tk, in my opinion, are the canvas,
text, and table widgets -- what are their equivalents in Motif? If you
make a comparison you will see that there is no contest at all.
