QSEclipse Blog

I created a blog for QSEclipse so that I don't end up creating off topic posts here... after this one. I'm not working on the project often but when something frustrates me enough I just can't help myself. When I make releases I'll post to the blog and also try to blog about anything I think is relevant in its development since the Quicksilver APIs are largely undocumented and is not open source.

EMF Observable Support

One of the recurring requests is for JFace Data Binding IObservable implementations for EMF. A lot of folks out there use EMF for their model and would like to hook that up with all the binding goodness of JFace Data Binding. If you have that itch you might want to follow bug 75625.

3.3M6 JFace Data Binding API Changes

3.3M6 was the API freeze and JFace Data Binding had a few changes in regards to API that were necessary for 1.0. All API changes can be found with this query. The most dramatic changes can be found in bugs 175840 and 177463.

175840 - [DataBinding] Remove BindingListener/BindingEvent from the API

The title doesn't quite do this justice. The change that will effect most consumers is that we removed BindSpec and the configuration of bindings has changes because of this. We have introduced 2 new classes to replace BindSpec: UpdateValueStrategy and UpdateListStrategy.

177463 - [DataBinding] SWT Observable API additions

The essence of this change is that all SWTObservables.observe*(...) methods are now untyped meaning they all accept a type of Control. This was done in anticipation of supporting multiple SWT versions. If we were to put the latest and greatest widgets in the method signatures it would prohibit us from using this class with Eclipse 3.2.

Monitoring JFace Data Binding Wiki Changes

Since Eclipsepedia is publishing recent changes I threw together a quick Yahoo Pipe to monitor changes to the JFace Data Binding articles. Our wiki documentation is going to be changing quite a bit and hopefully soon. If interested this is one way to keep track of those changes.

Update: This isn't working at the moment. When I can find some time I'll update the pipe.

My thanks go out to whoever got this working. When this popped up in NetNewsWire it made my day.

Quicksilver + Eclipse = QSEclipse

This is an off topic post as it has nothing to do with Data Binding so I'll keep it short...

In my spare spare time I've been hacking on a Quicksilver plugin to make it aware of Eclipse workspaces. If you're into Quicksilver and would like to learn more about the plugin head on over to the qseclipse project on Google Code. I consider it alpha but it works. Direct any feedback to the qseclipse Google group.

BeansObservables and registering for PropertyChangeEvents

In the past we've been a bit inconsistent about how BeansObservables registered for PropertyChangeEvents. In some cases we'd look for the addPropertyChangeListener(...) method that accepted the name of the property and in others cases we didn't. In order to ensure that your bean worked in all scenarios you had to implement both. As of this weekend we now abide by the bean spec (see section 7.4.1 and 7.4.5) in all cases. We look for the optional, with name, version first but fall back to the unnamed version if it is not found. Also if neither is found a warning is logged with the intention of making issues easier to debug.
