Hi,

I have a problem with my content assist,
I try to apply a label provider on my content assist but there is no effect

i use :

@Override
public void configureContentProposalLabelProvider(Binder binder) {
binder.bind(ILabelProvider.class).
annotatedWith(ContentProposalLabelProvider.class).
to(MyLabelProvider.class);
}

with

MyLabelProvider contains method getText() and getImage() for grammar element's...

hum sorry... Sad

so an example :

MylabelProvider.java :

...

String text(EnumDecl enumD) {
return enumD.getEnumName().getName();
}

String image(EnumDecl enumD) {
return "enum.gif";
}

...

MyDsl.xtext :

...

EnumDecl: enumName=EnumName leftC=LeftCurlyBracket propertyEnum+=EnumPropertyName (comma+=Comma propertyEnum+=EnumPropertyName)* rightC=RightCurlyBracket;

...

result in outline vieuw :

I would have the same icon in my content assist

I do not see any cross refs in the grammar you posted so there might
be a missanderstanding in what the label provider is used for.

Hi try to find out if the label provider that is injected to the
content assist is ever called for the place you are talking about. I
guess the answer is not. Never the less you can customize the
Complete methods in the proposal provider and call
createCompletionproposal with an image

by default the labelprovider applies to every element?
and well it just is not for my content assist !
this is why I thought that the method "configureContentProposalLabelProvider" should be used

No! what i say: it is only used for cross references and you do not have any cross refs
so it is not used at all in your case.

If you have something like ref=[Type] in your grammar. You don't have
=> you have to find a different solution. So have a look at the
complete methods in your proposal provider

Hi,

you did not post your complete grammar. thus its hard to tell how this could look like.
so let us asume your grammar would look like

EnumDecl: enumName=ID "{" propertyEnum+=ID ("," propertyEnum+=ID)* "}";

then you could do

public class MyDslProposalProvider extends AbstractMyDslProposalProvider {
	
	@Inject
	private IImageHelper imageHelper;
	
	@Override
	public void completeEnumDecl_EnumName(EObject model, Assignment assignment,
			ContentAssistContext context, ICompletionProposalAcceptor acceptor) {
		//icons/"Entity.gif
		acceptor.accept(createCompletionProposal("EnumName", "New EnumName", imageHelper.getImage("Entity.gif"), context));
	}

}

Ok ok

one last problem,
MyDSLProposalProvider is correctly call
but the method no... i think to need constructor or a method configure ?

Hi I do not understand your question: the method that's called
depends from the place you press crtl space
