Rev suport user defined events?

[Randall Reetz]

No answer?  Maybe i should make my question more clear...

I would like to write code that reacts dynamically to any changes made to objects in any stack.  I would like to do this without polling (without running a constant backround loop that checks every property of every object).  In order to do this efficiently, i would have to recieve legitimate events from the interpreter... as the changes are made.  But not every property generates a message when it is changed.  Button and fields respond as a matter of course to user interaction (messages are sent).  But many more properties do not generate events when they are set or changed.  As a result, a scripter has to detect these changes and react to them within each of the scripts they write.  This is cumbersome to say the least.  

If there was a convention for specifying which properties to watch... Which property changes that will initiate messages, then the programmer could write general purpose handlers to catch said event messages, greatly simplifying dynamic environment authoring.

Such a system could be used to customize the official event monitoring loop such that the interpretor would only pay attention to events of interest to a given stack.

One would "track" a prop

Can one tell rev to watch for and send an event associated with any property delta?

on setupevents
  track fillpat
end setupevents

on fillpat, target
  do something to target
end fillpat

Actuall, in supercard the universal property is called "textarrows".  If it is on, edit mode won't nudge objects with arrowkey input.

Thanks Guys. Just glad my memory hadn't gone on the fritz. I still  
can't see why it's not working for me now, but not worth  worrying  
about so long as I know it'll eventually work.
