It would really depend upon what kind of widget you wanted to process
the double-clicks for. To me the most useful applications of this
would be with draw and list widgets. For list widgets, note that the
event returned contains a field called CLICKS (1 or 2) that specifies
whether the event was generated by one or two clicks. For draw
widgets, you can probably modify David Fanning's advice for button
widgets.
