Yes, but:
a) does `w' refer to the widget that you wish to refresh?
b) are you actually using the value that is passed to the callback function?

Right. In refreshGraph(), you're still trying to refresh the widget to
which the callback is attached, not the one being passed as a
parameter. Try:
Window win=XtWindow((Widget) clientData);
instead. Also, from main_graphics(), `w' almost certainly isn't the
correct widget to be passing to XtAddCallback(). It looks like you
should be passing `draw', which means that you'll have to move the
XtAddCallback() to a point after where `draw' is defined.
