	Since I'm new to using widgets, I have had trouble working
with the fact that a callback can only send one piece of client
data. What are the ways around this. A specific case, although
general answers would be helpful, is saving a file. If i combine
a save button and an editable text widget, how do i have the
save function access the filename created, since the save callback
already will have the stuff to be saved as the client data.
Ideas floating in my head:
1) text widget modifies global variable Filemane	(ugly solution!!)
2) use text w to save filename as an ATOM? I don't
know much about these, but perhaps better than using a global.
3)?????

sorry, if this is a silly question, but i haven't had to share
data between widgets very much. Thanks!
