Hi

I'm using Eclipse 3.3.
I've a button that I only want to have enabled when something is changed.
What is the best way to accomplish this? Is it possible to bind the
enable-property of a button to a boolean in my domain with
DataBindingContext?

Thanks

You can create an observable on any Control's enabled property like this:
SWTObservables.observeEnabled(aControl)

Then you'll need an observable on the boolean in your domain, and bind
the two together with the SWT observable being the target.

Hope this helps,
Eric
