I should add that drag and drop in the same application can be done
easily, but it's hard to do it between your application and others (too
much window manager dependencies... )

Excellent. Thanks for the head start.

A couple of questions.

1) If I want to have a moving object, and not just a cursor that
represents the moving object, do I need to continually pack and unpack
the widget that holds the object and redraw it to give it the
appearance of moving? I know sometimes the redrawing can cause
applications to flicker too much, destroying the effect. I don't know
if there's an optimum way to do this.

2) Also, in reading I found an old module called Tkdnd (drag and
drop). It was an experimental module that was supposed to be updated
but never was. Now I can't find any more information on it. Does this
module still exist or work?

Thanks,
Marc

There is a nice example here using an as well nice Tree widget:

I think they will be answered when you look at the link (Tree.py) I posted
yesterday ;-)
