    How do I tell
    where the pointer is within my widget when this happens, and how do I
    tell what button was pushed?

Look at the Intrinsics documentation on callbacks (e.g. Section 5.1 in the
HP documentation).  The third argument to the callback, call_data, will for
the case of the XtNselect callback be the triggering X event; you can look
inside the event for the button number and the pointer position.  I couldn't
directly find the call_data documented in the HP stuff, I peeked at the source.
