Data Binding

[dunbarx at aol.com]

Hi.


 I do not think there is a native message similar to the "nameChanged" or "selectionChanged", in other words, a "propChanged". This would track any modification to a property and trigger a handler.


But the setProp and getProp control structures can handle this, I think.

Thanks everyone for answering my earlier questions on adapting MVC to rev.
 I have moved on to one more.  Although this one isn't really MVC.

A couple of the frameworks I have used have a concept called "data binding".
 This usually means something along the lines of when one property changes
another property is automatically updated.  The two properties are said to
be "Bound".  I like this concept and it seems like something that could be
useful to Live Code.

It seems that you could broadcast the change of a property of an object. And
other objects could listen for that change, and update themselves
accordingly.

Again, in effort to avoid re-inventing the wheel, I am curious if there any
one has tried this sort of thing and if it proved useful.

Thanks

Todd
