Well, what I've done is related... but I haven't done that particular usecase yet. How I envisioned things is that each of my widgets can be bound to a textual expression, where each part (separated by dots for example) generate an event listener, and thus create a chain of event listeners. I already have such a mechanism in my code with the difference that it is only evaluated once at the start. Extending it with the chain of event listeners shouldn't be too hard I think and this has been one of my long term goals since day 1 but I haven't got to it yet. > In qcl, I have a very > simplistic and not well scalable solution, but maybe some inspiration can be > taken from it: > > http://www.qxtransformer.org/a/qxtransformer.org/qxtransformer/Tutorial/Databinding > > What I like about this approach is its absolute simplicity - Each widget > gets a "updateClient" (get data from server) and "updateServer" (send data > to server) method, and everything else is done by the underlying mixin.
