java - How to override SourceViewerConfiguration in eclipse text editor -


i making eclipse plugin text hover extends eclipse text hover. trying make own "design" text hover using method 

public iinformationcontrolcreator gethovercontrolcreator()

in own texthover class but, information give in function return default when focused on hover. read need set iinformationcontrolcreator in sourceviewerconfiguration class using following function:

getinformationcontrolcreator

but, can't override sourceviewerconfiguration.

this override function:

package texthoverpackage; import org.eclipse.jface.text.itexthover; import org.eclipse.jface.text.source.isourceviewer; import org.eclipse.jface.text.source.sourceviewerconfiguration; public class texthoversourceviewerconfig extends sourceviewerconfiguration {     public itexthover gettexthover(isourceviewer sourceviewer, string contenttype) {         system.out.println("i in other place!!!");         return new javatexthover();     } }

the "i in other place!!!" message not printed tried wrote class in extension point in plugin.xml page error extension point class: 

org.eclipse.jface.text.source.sourceviewerconfiguration

can't create.

so happy know how override sourceviewerconfiguration class.

you can't change main sourceviewerconfiguration existing editor.

the way set different sourceviewerconfiguration create new editor.

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
