drag and drop

[Reza Naima <reza reza net>]

Well, i'm working on a jutebox-type program to work with a 3rd party piece of
hardware (slink-e from www.nirvis.com) to control multiple sony 200 disc
changers.  Now, I read a small blurb in the docs that meantioned that the
tree widget supported drag and drop -- however, I could find no other mention
of drag and drop support anywere in the docs, nor in any of the examples.
First off, I would like to do grag and drop from a tree wiget to a clist
wiget; is that supported?  and is it documented anywere or are there any good
examples?  

As a completly unrelated question to anyone that is using glade -- when it
creates a scrolled window wiget and puts something in it, it does so with a
container_add() rather than that ...._viewport_add() function -- which causes it
to be added but the scrollbars don't work, so i have to go in and change it
by hand.  Any idea why this kinda works? 

Thanks,
Reza
