Injection into ContentProvider / LabelProvider [message #1723460]

Hi!

I am still using SWT / JFace for my E4 RCP app. The content and label providers often need access to services that I usually provide via context injection. For example, the numbers shown in a table are calculated by a service request, or, the way numbers are formatted depends on user preferences, etc.

Is it a good idea to create the content / label providers via ContextInjectionFactory.make()?

Or should I pass the IEclipseContext reference to the providers?

Since I use EMF the adapter factory needs to be passed anyway. However, since my adapter factory is available via context injection, too, the first solution seems to have some benefits.

Thanks for your help.

Cheers,
Gernot.

By passing in an IEclipseContext, you're tying yourself to a particular implementation. I'd have your ContentProvider and LabelProvider annotate instances with @Inject and inject the instances with CIF.make().
