the example I just posted solves this by preferring the HAL value over the widget value. If the HAL value changes, the widget value is set accordingly; only if the HAL pin has not changed, a change in the widget value is considered. That way linking a halio_hscale1 to a non-zero signal, or a setp, will cause the widget to 'jump' to the HAL value. -m > > -- > atp > If you can't fix it, you don't own it. > http://www.ifixit.com/Manifesto > > ------------------------------------------------------------------------------ > Learn Graph Databases - Download FREE O'Reilly Book > "Graph Databases" is the definitive new guide to graph databases and their > applications.
