The problem of accessing program data from an action routine is an annoying one,
to which there is no "clean" solution.  I tend to use the X Context manager
to work around the problem by assigining data to the window of a widget, and
then retreiving this data from the action routine, since I have the widget (and
window) ID in the action routine I can associate unique data with each widget in
my application.

The Context manager is described in Scheifler, Gettys and Newman in section
10.12.
