Recipe for using XText providers elsewhere [message #641315]

Hi,

I'd like to be able to use the xtext Label Provider in another context, specifically for my EMF ItemProvider. Is there an easy obtain this adapter so that I can delegate to it from my EMF ItemProviderAdapter or is there an even better way to do this? Ideally, I'd just have everything delegated.

thanks,

Miles

Obtaining the adapter through the Guice Injector should do the trick (see §4.2.2 and §5.2 of the User Guide).

Hi Miente,

Thanks very much for the reference. I'll admit that I was hoping that you didn't use the word "injector" in your response and that I could get it programmatically. Like just grabbing an AdapterFactory.

I just now tried some stuff like:


		Injector inj = Guice.createInjector(new MyDSLRuntimeModule());
		ILabelProvider labelProvider = inj.getInstance(ILabelProvider.class);
		return labelProvider.getText(object);

But didn't work -- I'm probably still not grokking something. At some point I am really just going to have to sit down and figure all of that stuff out since E4 is using it as well. Very Happy

So I'll get back to this when I have a more intelligent question to ask.

cheers,

Miles

You could also instantiate the concrete classes using their constructors.

[QUOTE]

Oh I see, looks like I could just pass null for AdapterFactoryLabelProvider. I thought the delegate was being used in the dispatch chain but it looks like it isn't. At the very least I could just call the text methods assuming that I have such methods explicitly defined for each member.

BTW, one reason I wanted to do this is that I find the Xtext LabelProvider pattern to be much more easy to maintain then the EMF.Edit pattern, though the EMF.Edit pattern has important advantages as well of course.

cheers,

Miles
