Is it possible to pass client data thru a callback?  For example, I have (say)
20 buttons, each with almost identical behavior.  I'd like to write one callback
and pass client data to the callback which identifies which button was pressed.
I know I could subclass a button, but I'd prefer to use the existing kit's buttons.
I could also wrap the button returned by the kit in a monoglyph with a field
that identifies its contents, but that seems kinda like a kludge.
Any suggestions?

	Thanks,
