Hi Dimitri
Please can you ask this on StackOverflow? We want to improve the Q&A and our
SEO, and StackOverflow is a great way to do that.
Make sure you use the “qooxdoo” tag on your question - I think I’ll get an
email as soon as you’ve done it (I only signed up myself yesterday) but if you
want to post back here with a link that’s fine too.
Regards
John

Hi,
1. In my application, I'm loading/saving some data from/to qx.io.rest.Resource.
To hide the complexity of REST, I want to expose a simplified, high-level
interface to application components; think of load()/save() methods and some
events to monitor progress of operations.
In this scenario, there is a total of six events: [ load, save ] x [ starting,
success, failure ]. (I'm not interested in monitoring amount of data
transferred, since a typical request will consist of less than 1KB.)
What is the best/preferred way to model this event scheme? Do I use single
event type and pack all the info into event data, or do I use different event
types? Should I extend qx.event.type.Event, or should I adopt an existing class
like qx.event.type.Data?
2. In my application, I've got a key-value store that implements user
configuration (a la Apache Commons Configuration):
var config = new Configuration();
config.set("foo.bar", "baz");
config.get("foo.bar"); // "baz"
Dotted names are used to introduce configuration hierarchy. I also want the
following to work:
config.bind("foo.bar", target, "property.chain");
The idea here is to use traditional qooxdoo binding semantics; the difference
is, "foo.bar" does not denote a real property chain, it's merely a key name.
How should I implement this? Is it OK to completely override
qx.core.Object#bind with my implementation? Or should I model the internals of
Configuration class such a way that standard qx.core.Object#bind (delegating to
qx.data.SingleValueBinding) would work? The second scenario would probably
involve some generated classes (similar to what qx.data.marshal.Json#toClass
does) to reflect key names with real properties. Frankly, it seems a bit
complex to me. What do you think?
Cheers,
Dimitri
