	I'm having a problem with Wcl thats a bit um, difficult to work
around.  
	There are two instances of the problem; I'll start with the simpler
one first.
	
	Wcl programming is done on a callback basis, right?  The problem is
that an Xaw dialog has no callback.  What I really want to do is have a
callback in the OK button which says "call callback X with the value of the
text field".  It would probably be useful in some cases to specify the
"src" widget for the callback.
	This is more generally applicable too.  I have a list widget in
which I select a field; then a command button is clicked which wants to call
a callback with the value of the list widget.
	This seems to require a change in Wcl, to add a function to get the
value of a widget.  This would be something like WcRegisterValueFunction().

	Or have I missed something obvious?

Another feature is that the seats float, so that the airline can recover
them if the plane crashes into the ocean. -- Dave Barry
