Hello,
I created a new grammar with Xtext 2.11 (it works) and I want to personnalize the autocompletion.

For example, I have two objects in my grammar

 
      Environment:
	'ENV_TYPE' name=ID
	'Description' (Description=STRING)
 
 
      Test
	'TEST_TYPE' name=ID
	'Description' (Description=STRING)
        'Environment' Environment=[Environment]



I would like in eclipse during autocompletion (on Environment attribut in TEST object) retrieving Environment'ID and in the yellow part the environment's description (cf attachment)

index.php/fa/29434/0/

How do you do that ?

Thank you

You can have a look at IEObjectDocumentationProvider.
that one is used to calculate the hover tooltip (that is used for proposals as well)

Thansk for your answer but I need help again.
I follow this tutorial https://christiandietrich.wordpress.com/2011/07/16/hover-support-in-xtext-2-0-tutorial/ but it does not work.

Here my code :

import org.eclipse.emf.ecore.EObject;
import org.eclipse.xtext.documentation.IEObjectDocumentationProvider;

import com.google.inject.Inject;


public class SvcIEObjectDocumentationProvider implements IEObjectDocumentationProvider {


	public SvcIEObjectDocumentationProvider() {
		// TODO Auto-generated constructor stub
	}
	
@Override
	public String getDocumentation(EObject o) {
		return "Je mets ce que je veux";
	}

}


 
/*
 * generated by Xtext 2.11.0
 */
import com.google.inject.Inject
import org.eclipse.xtend.lib.annotations.FinalFieldsConstructor

/**
 * Use this class to register components to be used within the Eclipse IDE.
 */
@FinalFieldsConstructor
class SvcUiModule extends AbstractSvcUiModule {
	
	@Inject	
   def public Class<? extends SvcIEObjectDocumentationProvider> bindIEObjectDocumentationProvider() {
        return SvcIEObjectDocumentationProvider;
    }
	
}


When Eclipse loads, I pass by bindIEObjectDocumentationProvider() but my sentence "Je mets ce que je veux" does not appear.

What have I forgotten

Thank

@Inject
def public Class<? extends SvcIEObjectDocumentationProvider> bindIEObjectDocumentationProvider() {
return SvcIEObjectDocumentationProvider;
}

makes no sence. this is a binding not a injection

and the type is wrong
class MyDslUiModule extends AbstractMyDslUiModule {
	
    def public Class<? extends IEObjectDocumentationProvider> bindIEObjectDocumentationProvider() {
        return SvcIEObjectDocumentationProvider;
    }
}
